Description

The present invention relates to a vehicle seat, and more particularly to a vehicle seat in which the seat body, which has a seat back and a seat cushion, can be switched from its normal state.

2. Description of the Related Art Vehicle seats are known in the art that are switchable between a "normal state" and a "moving state" in which the seat body is slid from the normal state to a predetermined position in the front-rear direction of the seat.
Among these are vehicle seats that are equipped with a locking member that locks the movement of the seat body when in the "normal state," and an operating lever that is rotated to release the locked state of the locking member, with the operating lever being mounted in a position that is easy for the occupant to operate (see, for example, Patent Document 1).

The vehicle seat described in Patent Document 1 is a seat in which the seat body can be switched between a normal state and a sliding movement state, and is equipped with a locking mechanism that locks the movement of the seat body, and a slide lever (operating lever) that releases the locked state of the locking mechanism.
The slide lever is rotatably attached to a support frame provided on the front surface of the seat cushion via a shaft.
With the above configuration, when it is desired to switch the seat body from the normal state to the sliding state, the seated occupant can easily operate the slide lever.

JP 2009-101821 A

In a vehicle seat such as that disclosed in Patent Document 1, there has been a demand for further improvement in the operability of the operating lever by the occupant.
More specifically, when an occupant operates the control lever in the vehicle seat of Patent Document 1, the occupant needs to pull up the control lever with their finger hooked on the tip of the control lever. Therefore, while the control lever can be operated relatively smoothly when operated by an occupant sitting in the vehicle seat, there is a risk that the control lever cannot be operated properly when an occupant other than the occupant extends their hand to operate the control lever.

Furthermore, for vehicle seats such as those described in Patent Document 1, there was a demand for a vehicle seat that ensures the operability of the operating lever operated to switch the state of the seat body, while making the structure of the slide rail device including the operating lever as compact as possible.

The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a vehicle seat that improves the operability of an operating lever that is operated to switch the state of the seat body.
Another object of the present invention is to provide a vehicle seat in which the structure of a switching device including the operating lever is made compact while ensuring the operability of the operating lever.

The above problem is solved by the vehicle seat of the present invention, which comprises a seat body having a seat cushion, and which is switchable between a normal state and a sliding movement state in which the seat body is slid from the normal state in the fore-and-aft direction of the seat , and which comprises: a locking member attached to a predetermined position of the vehicle seat and which locks the movement of the seat body in the normal state; and an operating lever attached to a front portion of the seat cushion via a lever rotation shaft and which is rotated to release the locked state of the locking member, wherein the lever rotation shaft is attached to a base end portion of the operating lever in the extension direction or a portion close to the base end portion, and the operating lever is disposed on the front surface of the seat cushion, and a hook portion for an occupant to hook a finger thereon is formed on the outer surface of the operating lever between the lever rotation shaft and a tip portion opposite the base end portion .

In this case, the operating lever is storably attached to a lever storage member provided on the front surface of the seat cushion via the lever pivot shaft, and the lever storage member has a shape in which the bottom surface of the lever storage member is open, and the catch portion and the open portion of the lever storage member are connected to each other.
In addition, a display unit is formed on the outer surface of the operating lever to indicate that the operating lever is a member that is operated to switch the seat body from the normal state to the sliding movement state, and the display unit is arranged on the outer surface of the operating lever between the base end portion to which the lever rotation shaft is attached and the catch portion, and the display unit preferably has a diagram depicting the shape of the vehicle seat and a diagram depicting an arrow indicating the movement direction of the vehicle seat.
Preferably, the length of the display portion in the extending direction of the operating lever is longer than the length of the catch portion in the extending direction of the operating lever.
In addition, the seat body has a seat back, an armrest is attached to the seat back, and a part of the hook portion is preferably positioned at the same position as a part of the armrest in the left-right direction when viewed from the front of the seat .
The catch portion may be disposed at the lower end of the operating lever.

According to the present invention, it is possible to realize a vehicle seat with improved operability of an operating lever that is operated to switch the state of the seat body.
Furthermore, according to the present invention, it is possible to realize a vehicle seat in which the structure of the switching device including the operating lever is made compact while ensuring the operability of the operating lever .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle seat according to an embodiment of the present invention will be described below with reference to FIGS.
This embodiment relates to an invention of a vehicle seat having a seat body with a seat cushion, which can be switched between a normal state and a moving state in which the seat body is moved from the normal state, and which is equipped with a locking member attached to a predetermined position of the vehicle seat and which locks the movement of the seat body when in the normal state, and an operating lever attached to the front part of the seat cushion via a lever rotation shaft and which is rotated to release the locked state of the locking member, the lever rotation shaft being attached to the base end part of the operating lever in the extension direction, and a hook portion for an occupant to hook their finger on is formed on the outer surface of the operating lever between the lever rotation shaft and the tip part opposite the base end part.
The side of the seat back of a vehicle seat on which an occupant sits is the front side of the seat.

The vehicle seat S of this embodiment is, for example, a rear seat corresponding to the rear seat of a vehicle. Note that the vehicle seat S can also be used as a middle seat in the second row in a vehicle having three rows of seats in the longitudinal direction of the vehicle.
As shown in Figures 4A and 5A, the vehicle seat S is a seat that can be switched between a "normal state" in which the seat is positioned at a reference position in the fore-and-aft direction, and a "sliding state" in which the seat body is slid to a predetermined position in the fore-and-aft direction.
Furthermore, as shown in Figures 6A and 6B, the vehicle seat S is a seat that can be arranged in two different forms: an "used state" in which an occupant can be seated, and a "stored state" in which the seat body is stored in the vehicle floor.
Specifically, when the occupant pulls the recliner operating lever 44 at the top end of the seat body, the vehicle seat S switches from the "used state" shown in Fig. 6A to the "stored state" shown in Fig. 6B in which the seat body is tilted forward and folded and stored on the vehicle floor. Then, the occupant manually raises the seat body from the stored state to return to the "used state."

As shown in Figures 1 and 2, the vehicle seat S comprises a seat body having a seat back 1, a seat cushion 2, and a headrest 3, a support base 30 that supports the seat body from below, and a reclining device 40 that rotatably connects the seat back 1 to the support base 30 and locks the rotational movement of the seat back 1.
The vehicle seat S further includes a rail device 50 that is attached between the vehicle floor and the support base 30, supports the seat body so that it can move in the front-rear direction, and locks the movement of the seat body.

As shown in FIG. 1, the seat back 1 is a backrest portion that supports the back of an occupant from behind, and is configured by placing a pad member 1a on a back frame 10 shown in FIG. 2, which serves as a skeleton, and covering it with a skin 1b.
The seat cushion 2 is a seating portion that supports the occupant from below, and is configured by placing a pad member 2a on a cushion frame 20 shown in FIG. 2 that serves as a skeleton, and covering the pad member 2a with a skin 2b.
A mounting recess 2c for mounting an operating lever 60 is formed on the right side of the front surface of the seat cushion 2 in the seat width direction.
The headrest 3 supports the head of the occupant from behind, and is configured by placing a pad member 3a on a pillar (not shown) that serves as a core material, and covering it with a surface 3b.

As shown in Figure 2, the back frame 10 is a rectangular frame-like body that forms the skeleton of the seat back 1, and left and right connecting brackets 11 are attached to the lower part of the outer surface of the back frame 10 in the seat width direction for connecting it to the support base 30.
The connecting bracket 11 is made of a bow-shaped sheet metal member extending in the vertical direction, and the upper end of the connecting bracket 11 is attached to the back frame 10 and the lower end is attached to the support base 30.
A reclining device 40 (reclining body 41) that rotatably connects the back frame 10 to the support base 30 is attached to the lower end of the right-side connecting bracket 11, and a back rotation shaft 42 that is journaled on the support base 30 in the seat width direction is attached to the lower end of the left-side connecting bracket 11.

As shown in Figure 2, the cushion frame 20 is a rectangular frame-like body that forms the skeleton of the seat cushion 2. It is mainly composed of left and right side frames 21 arranged on either side in the seat width direction, a plate-shaped pan frame 22 that connects the front portions of each side frame 21, a pipe-shaped rear connecting frame 23 that connects the rear portions of each side frame 21, and multiple elastic springs 24 that are hooked onto the pan frame 22 and rear connecting frame 23 and extend in a snake-like shape.

The side frames 21 are made of sheet metal members extending in the front-to-rear direction of the seat, and a connecting link 25 for connecting to the rail device 50 is attached to the front portion of the inner surface of the side frame 21. In addition, a cushion rotation shaft 26 for connecting to the back frame 10 is attached to the rear portion of the inner surface of the side frame 21.
The connecting links 25 are members that rotate to store the seat body (seat cushion 2) on the vehicle floor side, and are attached as a pair between the cushion frame 20 and the rail device 50.
A mounting hole 22a for mounting the operating lever 60 and lever storage member 70 shown in FIG. 1 is formed on the right side of the front surface of the pan frame 22 in the seat width direction.

As shown in FIG. 2, the support base 30 is a base member that supports the seat body, and connects the back frame 10 (connection bracket 11) and the rail device 50 (upper rail 52) in the vertical direction.
In detail, the support base 30 is arranged on the side in the seat width direction and comprises an approximately L-shaped side base portion 31 attached to the upper surface of the upper rail 52, and a pipe-shaped base connecting portion 32 connecting the left and right side base portions 31.

As shown in FIG. 2, the reclining device 40 is disposed between the right connecting bracket 11 and the right support base 30 (base connecting portion 32) in the seat width direction.
The reclining device 40 is mainly composed of a reclining body 41 that is driven when rotating the back frame 10, a back rotation shaft 42, a spiral spring 43 that urges the back frame 10 to rotate forward around the back rotation shaft 42, a reclining operation lever 44 shown in FIG. 1 that is operated to release the locked state of the back frame 10, and a reclining cable (not shown) that connects the reclining operation lever 44 and the reclining body 41.

The reclining body 41 has a known locking mechanism, and the state of the back frame 10 can be switched between a locked state in which it is fixed to the support base 30 and an unlocked state in which it can rotate relative to the support base 30.
The back rotation shaft 42 is supported on the back frame 10 side and the support base 30 side in the seat width direction, and one end of the spiral spring 43 is engaged with the back frame 10 side and the other end is engaged with the support base 30 side.
The recliner cable (not shown) is pulled by the operation of the recliner operating lever 44 to switch the seat back 1 from a locked state to an unlocked state.

In the above configuration, the reclining device 40 locks the back frame 10 in the upright position shown in Figure 6A. When the reclining operation lever 44 is operated, the locked state is released, and the biasing force of the spiral spring 43 causes the back frame 10 to rotate forward, allowing it to be folded toward the vehicle floor together with the cushion frame 20 (see Figure 6B).

As shown in FIGS. 1 to 5C, the rail device 50 is a device that supports the seat body so that it can slide in the front-rear direction of the seat, and is disposed between the seat body and the vehicle floor.
The rail device 50 is fixed to the vehicle floor and is mainly composed of left and right lower rails 51 extending in the fore-and-aft direction of the seat, left and right upper rails 52 supported slidably along the lower rails 51, a locking member 53 that locks the upper rails 52 so that they cannot slide relative to the lower rails 51, an operating lever 60 that is operated to release the locked state of the locking member 53, a lever pivot shaft 54 that serves as the pivot shaft of the operating lever 60, and a rail cable 55 that connects the locking member 53 and the operating lever 60.

As shown in Figures 4C and 5C, the locking member 53 is disposed between the left and right upper rails 52, and is a member that rotates between a locked position in which the upper rails 52 are locked so that they cannot slide relative to the lower rails 51, and an unlocked position.
In more detail, the locking member 53 is mainly composed of a locking body 53a and a pivoting lever 53c that connects the locking body 53a and the rail cable 55 and pivots around a pivoting shaft 53b as the rail cable 55 is pulled.
The lock body 53a and the rotating lever 53c are biased to the lock position by a spring (not shown).

The lock body 53a is attached to the inner surface of the left upper rail 52, and operates (rotates) to disengage an engagement groove (not shown) provided in the upper rail 52 from an engagement claw (not shown) provided in the lower rail 51 in conjunction with the rotational movement of the pivot lever 53c, thereby releasing the locked state of the upper rail 52.
The rotating lever 53c is a rotating member that is long in the vertical direction and is attached via a rotating shaft 53b to the inner surface of the upper rail 52. The rotating lever 53c functions as a transmission member that transmits the pulling action of the rail cable 55 to the lock body 53a.

As shown in Figures 4A to 4C, the rail cable 55 has one end 55a attached to the operating lever 60, a folded portion (not shown) that extends from the one end 55a to the rear of the seat and is folded back, and the other end 55b that extends from the folded portion to the front of the seat and is attached to the locking member 53 (rotating lever 53c).
The rail cable 55 is pulled by the rotational movement of the operating lever 60 and acts to switch the locking member 53 from the locked position to the unlocked position.

As shown in Figures 1, 3A, 3B, and 4B, the operating lever 60 is a lever that is rotated to release the locked state of the rail device 50, and is attached to the front portion of the seat cushion 2 in the vehicle seat S.
More specifically, the operating lever 60 is stored in a lever storage member 70 provided on the front surface of the seat cushion 2 and is attached to the lever storage member 70 via a lever rotation shaft 54 so as to be rotatable relative to the lever storage member 70 .
The operating lever 60 is a lever that is long in the vertical direction, and its upper end portion corresponds to the "base end portion" and its lower end portion corresponds to the "tip portion."

The operating lever 60 is mainly composed of a lever front portion 60a that forms the outer surface of the operating lever 60 and extends vertically; a lever upper portion 60b that extends from the upper end of the lever front portion 60a toward the rear of the seat; left and right lever side portions 60c that extend rearward from both ends of the lever front portion 60a in the seat width direction and are connected to the lever front portion 60a and lever upper portion 60b; and a lever central portion 60d that has an inverted U-shaped cross section and protrudes toward the rear of the seat from the center of the lever front portion 60a in the seat width direction.

An indicator 61 is formed on the outer surface of the lever front portion 60a to indicate that the operating lever 60 is a member that is operated to switch the seat body from the "normal state" to the "sliding state."
Furthermore, a hook 62 for the occupant to hook his/her finger is formed on the outer surface of the lever front portion 60a at a position below the display portion 61 so as to penetrate the lever front portion 60a.
The display portion 61 and the catch portion 62 are arranged vertically side by side on the outer surface of the operating lever 60 .

A lever rotation shaft 54 that is long in the seat width direction is supported at the upper end portions (base end portions) of the left and right lever side portions 60c. The lever rotation shaft 54 is supported by the operating lever 60 (lever side portions 60c) and the lever storage member 70 in the seat width direction.
A cable attachment portion 63 for attaching the rail cable 55 (one end portion 55a) is formed on the outer surface of the lever central portion 60d between the lever rotation shaft 54 and the catch portion 62 in the vertical direction.

As shown in Figure 3A, the display unit 61 illustrates that the operating lever 60 is an operating member for sliding the seat body, and the illustration is formed in an uneven shape on the front surface of the operating lever 60.
The vertical length of the display portion 61 is longer than the vertical length of the hook portion 62 .
The catch portion 62 is a generally rectangular catch hole, and is formed at a position closer to the lower end portion (tip portion) of the operating lever 60 than to the upper end portion (base end portion).
The vertical length of the catch portion 62 is longer than the vertical length of the lower end portion of the operating lever 60. In addition, the width of the catch portion 62 is longer than the width of the display portion 61.

In the above configuration, as shown in FIG. 3A, the operating lever 60 is provided with the catch portion 62, so that the occupant can easily rotate the operating lever 60 by using the catch portion 62.
More specifically, the occupant can easily grip the operating lever 60 by hooking his/her fingers on the catch portion 62 (the edge portion of the catch portion 62) and the lower end portion of the operating lever 60.

As shown in FIG. 7A, a hook recess 64 may be formed separately at the lower end portion of the operating lever 60 (the edge portion of the hook portion 62) to make it easier for the occupant's finger to be hooked thereon.
The latch recesses 64 are formed on the upper surface of the lower end portion of the operating lever 60, and are preferably formed in two locations at a predetermined interval in the seat width direction. Also, the latch recesses 64 preferably have a smoothly curved surface.
Alternatively, as shown in FIG. 7B, a hooking uneven portion 65 may be separately formed at the lower end portion of the operating lever 60 to make it easier for the occupant's finger to be hooked thereon.
The latching uneven portion 65 is a fine uneven portion formed by embossing the entire upper surface of the lower end portion of the operating lever 60 .

In the above configuration, as shown in FIG. 4B, the lower end of the operating lever 60 is bent and extends toward the inside of the seat cushion 2 in the thickness direction of the operating lever 60.
More specifically, the lower end of the operating lever 60 is disposed inside the seat cushion 2 with respect to the lever rotation shaft 54 in the thickness direction of the operating lever 60 .
Therefore, the occupant can easily hook his/her finger on the lower end portion of the operating lever 60. This improves the operability of the operating lever 60.

In addition, in the above configuration, as shown in Figure 4B, the outer surface of the lower end portion of the operating lever 60 is formed continuously with the outer surface of the operating lever 60 and extends while curving toward the inside of the seat cushion 2 in the thickness direction of the operating lever 60.
In addition, the lower end of the operating lever 60 is disposed inside the seat cushion 2 with respect to the catch portion 62 .
Therefore, the occupant can easily hook his/her fingers on the hook portion 62 and the lower end portion of the operating lever 60. This improves the occupant's grip on the operating lever 60, thereby improving the operability of the operating lever 60.

As shown in FIGS. 1, 3A, 3B, and 4B, the lever storage member 70 is a storage plate that rotatably supports the operating lever 60, and is fitted into the mounting recess 2c of the seat cushion 2.
The lever storage member 70 has a box shape with an open bottom.
In more detail, the lever storage member 70 is mainly composed of left and right side portions 70a arranged at a predetermined interval in the seat width direction, an upper portion 70b connecting the upper ends of the left and right side portions 70a, a rear portion 70c connecting the rear ends of the left and right side portions 70a, left and right side flange portions 70d bending from the front ends of the left and right side portions 70a and protruding outward in the seat width direction, and an upper flange portion 70e bending from the front end of the upper portion 70b and protruding upward.

A lever rotation shaft 54 that is long in the seat width direction is supported at the upper end portions of the left and right side portions 70a.
The rear portion 70c is formed with a cable attachment portion 71 for attaching the rail cable 55 (one end portion 55a) and a frame attachment portion 72 for attachment to the cushion frame 20 (pan frame 22).
The cable attachment portion 71 is disposed at a position higher than the frame attachment portion 72 .

In the above configuration, as shown in FIG. 4A, the catch portion 62 of the operating lever 60 and the open portion 73 located at the lower end of the lever storage member 70 are in communication with each other.
This makes it possible to prevent foreign matter from accumulating on the edge of the catch portion 62 or inside the lever storage member 70. In other words, even if foreign matter enters through the catch portion 62, the foreign matter can be moved to the outside from the bottom surface of the lever storage member 70.

In addition, in the above configuration, as shown in Figures 1 and 4A, when the operating lever 60 is in the locked position, the front surface of the seat cushion 2, the front surface of the operating lever 60, and the front surface of the lever storage member 70 are approximately flush with each other.
Therefore, the operating lever 60 can be compactly arranged in the front part of the seat cushion 2 without impairing the design of the vehicle seat S.

Next, the vehicle seat unit U will be described with reference to FIG.
The vehicle seat unit U is configured by arranging a plurality of vehicle seats S in the seat width direction.
In the vehicle seat unit U, the operating levers 60 (60A, 60B) provided on the adjacent vehicle seats S are positioned at a central position in the seat width direction of the vehicle seat unit U.
Therefore, for example, an occupant can operate each operating lever 60 from a position forward of the vehicle seat S, and can switch the states of the adjacent seat bodies together.

<Second embodiment of vehicle seat>
Next, a second embodiment of the vehicle seat will be described with reference to FIGS.
It should be noted that the description of the same content as that of the vehicle seat S described above will be omitted.
The vehicle seat S2 of the second embodiment differs from the vehicle seat S mainly in that it is provided with an ottoman device 180, and the configuration of the operating lever 160 is also different.

The vehicle seat S2 is a seat that can be arranged in three different configurations: an "used state" in which an occupant can sit, a "stored state" in which the seat body is stored in the vehicle floor, and a "tip-up state" in which the seat body is flipped up.
As shown in FIG. 14, a recessed storage floor is provided in front of the vehicle seat S2 and is positioned lower than the vehicle body floor.

As shown in FIGS. 8 and 9, the ottoman device 180 is attached to the front end portion of the seat cushion 102 and is disposed in the center portion of the seat cushion 102 in the seat width direction.
The ottoman device 180 is mainly composed of an ottoman rotation shaft 181 that extends in the seat width direction and is journaled at the front end portion of the seat cushion 102, a leg support member 182 that rotates relative to the seat cushion 102 around the ottoman rotation shaft 181 as the rotation center, and a movable unit (not shown) for moving the leg support member 182.

The leg support member 182 is rotatable between a "storage position" shown in Figure 8 in which it is stored inside the seat cushion 102, a "deployed position" shown in Figure 9 in which it is deployed from the storage position forward of the seat cushion 102, and a "tip-up position" shown in Figure 10 in which it stands up (vertically) above the "deployed position."
The leg support member 182 is mainly composed of a support side end portion 182a supported on the front end portion of the seat cushion 2, and an unfolding side end portion 182b formed to be wider in the seat width direction than the support side end portion 182a.

As shown in FIG. 10, a plurality of hook-shaped locking members 183 are attached to the front end portion of the bottom surface of the leg support member 182 (deployment side end portion 182b) at predetermined intervals in the seat width direction.
The locking members 183 are umbrella-shaped hook members, and are disposed at the center of the leg support member 182 in the seat width direction and at both end portions in the seat width direction.
As shown in FIG. 11, a plurality of hook-shaped locking members 184 are also attached to the upper portion of the rear surface of the seat back 101 at predetermined intervals in the seat width direction.

The above-described configuration allows for seat arrangement, and makes it possible to realize a vehicle seat S2 in which the ottoman device 180 is compactly arranged.
10, when luggage with a handle is placed on the seat cushion 102, the handle of the luggage can be locked with the locking member 183. This makes it possible to prevent the luggage from moving.
Furthermore, with the above configuration, by moving the leg support member 182 to the "tip-up position," when, for example, luggage with a handle is placed on the seat cushion 102, the mesh-like net can be locked with the locking members 183 and 184 so as to cover the luggage from above. This makes it possible to easily secure the luggage.

As shown in FIGS. 8, 12A, and 12B, the operating lever 160 is a lever that is rotated to release the locked state of the rail device 150.
The operating lever 160 has a generally box-like shape with an open bottom.
In more detail, the operating lever 160 is mainly composed of a lever front portion 160a that forms its outer surface and extends longitudinally in the vertical direction, a lever upper portion 160b that extends from the upper part of the lever front portion 160a toward the rear of the seat, left and right lever side portions 160c that extend toward the rear of the seat from both ends of the lever front portion 160a in the seat width direction and are connected to the lever front portion 160a and the lever upper portion 160b, and a lever rear portion 160d that connects the rear ends of the left and right lever side portions 160c.

A display portion 161 and a catch portion 162 are formed on the outer surface of the lever front portion 160a. The vertical length of the catch portion 162 is longer than the vertical length of the display portion 161. This allows the hole of the catch portion 162 to be formed large.
A lever rotation shaft 154 that is long in the seat width direction is supported at the upper end portions of the left and right lever side portions 160c. The lever rotation shaft 154 is supported by the operating lever 160 and the lever storage member 170 in the seat width direction.
A cable attachment portion for attaching a rail cable (not shown) is formed on the inner surface of the lever rear portion 160d.

Even with the above configuration, it is easier for the occupant to hook his/her fingers on the operating lever 160 and grip it, thereby improving the operability of the rail device 150.
In particular, when the vehicle seat S2 is a rear seat (middle seat), an occupant seated in the front seat can reach out and hook their finger on the hook portion 162, allowing them to operate the operation lever 160. Specifically, the occupant can easily move the vehicle seat S2 forward by pulling the vehicle seat S2 forward with their finger hooked on the operation lever 160. Naturally, the vehicle seat S2 can also be moved rearward by pushing it rearward.

Next, the vehicle seat unit U2 will be described with reference to FIG.
