Description

The present invention relates to a vehicle seat and a method for manufacturing the vehicle seat, and in particular to a vehicle seat having two connected seat members and a method for manufacturing the vehicle seat.

When attaching a seat cushion having a cover to a cushion frame, the rear end of the seat cushion is passed through the gap between the seat back and the rear pipe of the cushion frame (see Patent Document 1).

JP 2017-214067 A

However, because the size of the gap between the seat back and the rear pipe of the cushion frame is usually narrower than the height of the rear end of the seat cushion, when inserting the rear end into the gap, there is a risk that the rear end will hit the rear pipe and not pass through the gap. As a result, when manufacturing vehicle seats, workers must insert the seat while holding down the rear end to prevent it from hitting the rear pipe, which reduces workability.

Therefore, the present invention was made in consideration of the above problems, and its purpose is to provide a vehicle seat and a method for manufacturing a vehicle seat in which a protrusion protruding from the end of the pad can be easily inserted between the skeleton frame and the seat member.

The above problem is solved by the vehicle seat of the present invention, which provides a vehicle seat having two connected seat members, each of the two seat members comprising a pad, a skin covering the pad, and a frame constituting the skeleton of the seat members, the pad of one of the seat members having a protrusion at a portion connected to the other seat member and disposed between the frame of the one seat member and the other seat member, the skin of the one of the seat members having a cylindrical body on the side connected to the other seat member formed by an extension extending a predetermined distance from an end portion and covering the surface of the protrusion, and a member joined to both side portions of the extension and covering part of the back surface of the protrusion, and the member covering part of the back surface of the protrusion abuts against the frame of the one of the seat members .

According to the vehicle seat of the present invention configured as described above, the protruding portion protruding from the end of the pad is covered by the extension and the grip. Therefore, when passing the protruding portion through the gap, the protruding portion is prevented from hitting the frame, and the protruding portion can be easily inserted between the frame and the pad of another seat member. This improves the workability when assembling the vehicle seat.

In the above configuration, the member covering a portion of the rear surface of the protrusion may be a gripping portion that grips the protrusion.
In the above configuration, both side portions of the extension portion and both side portions of the grip portion may be joined together, and the extension portion and the grip portion may form the cylindrical body.
In the above configuration, the protrusion may be disposed so as to pass through the inside of the cylindrical body .
Furthermore , in the above configuration, the one seat member is a seat cushion on which an occupant sits, and the other seat member is a seat back that is connected to a rear end of the seat cushion and supports the occupant's back, and the extension portion and the grip portion extend from a rear end of a cover of the seat cushion to cover the protruding portion of the seat cushion.
With the above configuration, when the protrusion at the rear end of the seat cushion is passed between the frame of the seat cushion and the seat back, the protrusion is prevented from hitting the frame, for example a pipe member, and the protrusion can be easily passed between the frame and the seat cushion.

In the above configuration, the extension portion may have a thickness smaller than a thickness of the skin.
By making the thickness of the extension portion extending from the skin thinner than the thickness of the skin, the manufacturing cost can be reduced even if the extension portion is made of the same material as the skin.

In the above configuration, the frame may have a pressure receiving portion that supports the pad, and an attachment portion that is fixed to the pressure receiving portion may be provided at an end of the skin.
By providing an attachment portion at the end of the cover to be fixed to the pressure receiving portion, the pad can be easily fixed.

In the above configuration, a claw portion is formed on the frame or the pressure receiving portion,
The attachment portion of the skin may be hooked onto the claw portion and fixed.
The mounting part can be easily fixed to the frame or the pressure receiving part by hooking the mounting part onto the claw part and fixing it.

In the above configuration, the attachment portion may include a wire member that is hooked onto a plurality of the claw portions formed on the frame or the pressure-receiving portion.
By hooking the wire member of the mounting portion onto the claw portion, the mounting portion can be fixed more easily and at a lower cost than, for example, a conventional mounting portion formed in a hook shape.
In the above configuration, it is preferable to include a headrest, a reclining mechanism, and a slide rail.

Furthermore, according to a manufacturing method for a vehicle seat of the present invention, the above problem is solved by a manufacturing method for a vehicle seat having two connected seat members, each of the two seat members comprising a pad, a skin covering the pad, and a frame constituting the skeleton of the seat members, the pad of one of the seat members having a protrusion at a portion connected to the other seat member, the skin of the one of the seat members having a cylindrical body on the side connected to the other sheet member, the cylindrical body being formed by an extension extending a predetermined distance from an end portion and covering a surface of the protrusion, and a member joined to both side portions of the extension and covering a portion of the back surface of the protrusion, the method including a step of passing the protrusion into the inside of the cylindrical body, and, with the protrusion covered by the cylindrical body, passing the protrusion between the frame of the one of the seat members and the other of the seat members, and the member covering the portion of the back surface of the protrusion abuts against the frame of the one of the seat members .

The manufacturing method for a vehicle seat according to the present invention covers the protruding portion protruding from the pad with the extension and grip, preventing the pad from hitting the frame and allowing the protruding portion to be easily inserted between the frame and another seat member, improving workability when assembling the vehicle seat.

Furthermore, in the above-mentioned method for manufacturing a vehicle seat, the frame may have a pressure-receiving portion that supports the pad, and the method may include a step of fixing the pad to the frame by hooking an attachment portion provided at an end of the skin onto a claw portion formed on the frame or the pressure-receiving portion.
The pad can be easily fixed to the frame by hooking the attachment portion provided at the end of the cover onto the claw portion formed on the frame or the pressure receiving portion.

According to the vehicle seat of the present invention, the protruding portion protruding from the end of the pad is covered by the extension portion and the grip portion. This prevents the protruding portion from hitting the frame and allows the protruding portion to be easily inserted between the frame and the pad of another seat member. This improves the workability when assembling the vehicle seat.
With the above configuration, when the protrusion at the rear end of the seat cushion is passed between the frame of the seat cushion and the seat back, the protrusion is prevented from hitting the frame, for example a pipe member, and the protrusion can be easily passed between the frame and the seat cushion.
Furthermore, by making the thickness of the extension portion extending from the skin thinner than the thickness of the skin, the cost can be reduced even if the extension portion is made of the same material as the skin.
In addition, since the protrusion passes through the inside of the cylindrical body formed by the extension portion and the gripping portion, the protrusion is prevented from shifting in the width direction of the vehicle seat when placed between the frame and the other seat component, making it easier to pass through.
Furthermore, by providing an attachment portion at the end of the cover to be fixed to the pressure-receiving portion, the pad can be easily fixed.
Furthermore, by hooking the mounting portion onto the claw portion and fixing it, the mounting portion can be easily fixed to the frame or the pressure receiving portion.
Furthermore, by hooking the wire member of the mounting portion onto the claw portion, the mounting portion can be fixed more easily and at a lower cost than, for example, a conventional mounting portion formed in a hook shape.
In addition, with the manufacturing method for a vehicle seat according to the present invention, the protruding portion protruding from the pad is covered by the extension portion and the gripping portion, thereby preventing the pad from hitting the frame and allowing the protruding portion to be easily inserted between the frame and another seat component, improving workability when assembling the vehicle seat.
Furthermore, the pad can be easily fixed to the frame by hooking the attachment portion provided at the end of the skin onto the claw portion formed on the frame or the pressure receiving portion.

<<Basic configuration of the vehicle seat according to the present embodiment>>
A basic configuration of a vehicle seat according to this embodiment (hereinafter, vehicle seat S) will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a perspective view of the vehicle seat S. In Fig. 1, for convenience of illustration, a part of the vehicle seat S is illustrated with trim covers (cushion trim cover 17, back trim cover 27) removed.

The vehicle seat S is a seat that is placed on the vehicle body floor and in which a vehicle occupant sits. In this embodiment, the vehicle seat S is used as a front seat that corresponds to the front seat of the vehicle. However, this is not limited to this, and the vehicle seat S may be a rear seat of the vehicle, and may also be used as a second-row middle seat or a third-row rear seat in a vehicle that has three rows of seats in the front-to-rear direction.

As shown in FIG. 1, the main components of the vehicle seat S are a seat cushion S1 that serves as a seating portion that supports the buttocks of the seated person, a seat back S2 that serves as a backrest that supports the back of the seated person, and a headrest S3 that is disposed on the upper part of the seat back S2 and supports the head of the seated person. The seat cushion S1 corresponds to one seat member of the present invention, and the seat back S2 corresponds to the other seat member of the present invention. The seat cushion S1 and the seat back S2 are connected with a reclining mechanism 60 in between. Although not shown, a slide rail is provided on the lower part of the seat cushion S1, and the slide rail allows the vehicle seat S to be placed on the vehicle floor in a state in which it can slide back and forth.

A seat frame F shown in FIG. 2 is provided inside the vehicle seat S, and the seat frame F is mainly composed of a cushion frame 1 and a back frame 2. The cushion frame 1 forms the framework of the seat cushion S1 in the seat frame F, and the back frame 2 forms the framework of the seat back S2 in the seat frame F.

The rear end of the seat cushion S1 is connected to the lower end of the seat back S2. The seat cushion S1 is constructed by placing a cushion pad 16 on a cushion frame 1, and covering the cushion pad 16 with a cushion trim cover 17. The seat back S2 is constructed by placing a back pad 26 on a back frame 2, and covering the back pad 26 with a back trim cover 27.

The cushion pad 16 and the back pad 26 are made of a urethane base material formed by foam molding using, for example, a urethane foaming agent. The cushion pad 16 and the back pad 26 correspond to the pads of the present invention. The cushion trim cover 17 and the back trim cover 27 correspond to the skin of the present invention and are made of cloth, film, cloth, leather, sheet, etc., and are attached to cover the cushion pad 16 and the back pad 26 while being stretched with a predetermined tension.
In this embodiment, when the cushion trim cover 17 is attached to the cushion pad 16, the ends of the cushion trim cover 17 are attached to predetermined locations, and the method of attachment will be described later.

In this embodiment, the cushion frame 1 has an outer shape of a substantially rectangular frame, as shown in FIG. 2. The main components of the cushion frame 1 are a pair of cushion side frames 12 that respectively form the left and right ends in the seat width direction, a pan frame 11 that forms the front end of the cushion frame 1, and a spring 14 (pressure receiving portion).

The two cushion side frames 12 are spaced apart in the left-right direction and are arranged to extend in the front-rear direction of the vehicle in order to define the width of the cushion frame 1. A front pipe 13a that connects the two cushion side frames 12 is attached to the front end, and a rear pipe 13b is attached to the rear end.

The pan frame 11 is fixedly joined to the front sides of the pair of cushion side frames 12, and the left and right cushion side frames 12 are connected at the front side by the pan frame 11. More specifically, the left and right ends of the pan frame 11 are each fixed to a flange provided on the cushion side frame 12 by a fixing means such as welding.

The pan frame 11 is primarily intended to support the thighs of a seated occupant, and is a frame made of a metal plate with a nearly flat upper surface and a generally rectangular shape.

A number of springs 14 (S-springs) are arranged in the seat width direction between the left and right cushion side frames 12 as pressure receivers. These springs 14 extend long in the seat front-rear direction. The front end of the spring 14 is fixed to the front pipe 13a by an engagement hook 14c, and the rear end of the spring 14 is fastened to the rear pipe 13b by an engagement hook 14d. The spring 14 is also provided with a pressure receiver plate 14a.

The back frame 2 is mainly made of pipes processed into a rectangular frame shape, and as shown in FIG. 2, the back frame 2 includes an inverted U-shaped upper frame 21, a pair of back side frames 22 forming the left and right ends in the seat width direction, and a lower frame 23 connecting the lower ends of the pair of back side frames 22. The back frame 2 is also provided with a pressure receiving plate 24 suspended from the back frame 2, and a suspension frame 25 for suspending the pressure receiving plate 24 is provided so as to span the left and right back side frames 22. A cylindrical headrest guide 21a is attached to the center of the upper end of the back frame 2. The headrest pillar 61 extending from the lower end of the headrest S3 is inserted into this headrest guide 21a, thereby attaching the headrest S3 to the seat back S2.

The materials that make up the cushion frame 1 are made of materials that have sufficient rigidity so as not to deform significantly when subjected to a load, such as metal materials such as steel and aluminum alloys. The members that make up the cushion frame 1 are joined together by welding, but bolts and adhesives may also be used in combination as a joining means.

<<Cushion pad and cushion trim cover>>
Next, the configuration of the cushion pad 16 and the cushion trim cover 17 will be described with reference to Fig. 3 to Fig. 5. In the following description, the "cushion front-rear direction" refers to the direction from the front end to the rear end of the seat cushion S1, and coincides with the front-rear direction of the vehicle seat S. In the cushion front-rear direction, the "front" refers to the side where the free end of the seat cushion S1 is located, and is not connected to the seat back S2.

As described above, the cushion pad 16 is a member that is placed on the cushion frame 1 and receives the buttocks of an occupant. In the seat cushion S1, the cushion pad 16 is provided so as to surround the cushion frame 1, which serves as a framework. In order to fix the cushion pad 16 to the cushion frame 1, the cushion pad 16 is covered with a cushion trim cover 17 and then inserted into the gap V between the seat back S2 and the rear pipe 13b of the cushion frame 1 (see FIG. 5). Therefore, the cushion pad 16 has a protrusion 16a at the rear end of the cushion pad 16 that is inserted into the gap V. In other words, the cushion pad 16 has a protrusion 16a that is disposed between the cushion frame 1 (more specifically, the rear pipe 13b) of the seat cushion S1 and the seat back S2 at the portion where the seat cushion S1 and the seat back S2 are connected.

The cushion trim cover 17 is a member that covers the cushion pad 16 of the seat cushion S1, and has a cover body 17a and an extension 18. The cover body 17a covers the top surface, front surface, and both side surfaces of the cushion pad 16. As shown in FIG. 3, the extension 18 is provided at the rear end of the cushion trim cover 17, more specifically, at the rear end of the cover body 17a, so as to extend a predetermined distance L toward the rear. The extension 18 covers the surface of the protruding portion 16a of the cushion pad 16.

When attaching the cushion pad 16 to the cushion frame 1, the extension 18 is inserted into the gap V together with the protrusion 16a, and the portion that extends beyond the rear pipe 13b is folded back and attached to the bottom side of the cushion pad 16 (see FIG. 5). More specifically, the tip of the extension 18 is provided with an attachment portion 18c, which is attached to the claw portion 15c formed on the pressure plate 14a of the spring 14.

As shown in Figures 4 and 5, the cushion trim cover 17 has a gripping portion 19 on the back side of the extension portion 18, which grips the protruding portion 16a and covers the back surface of the protruding portion 16a. The extension portion 18 extends from the cover body 17a and covers the surface of the protruding portion 16a. Also, as shown in Figures 4 to 6, both sides of the extension portion 18 and both sides of the gripping portion 19 are joined by sewing, and the extension portion 18 and the gripping portion 19 form a cylindrical body C. The protruding portion 16a of the cushion pad 16 is positioned through the inside of the cylindrical body C.

Conventional cushion trim covers are not provided with a gripping portion 19 for gripping the protrusion 16a. Therefore, when attempting to pass the extension 18 and protrusion 16a through the gap V, the protrusion 16a may hit the rear pipe 13b, and even if the extension 18 is pulled, the protrusion 16a may not pass through the gap V. Therefore, when attaching the cushion pad 16, the worker holds down the protrusion 16a to reduce the thickness of the protrusion 16a before inserting the extension 18 and protrusion 16a into the gap V. Inserting the extension 18 and protrusion 16a while holding down the protrusion 16a reduces workability.

In the cushion trim cover 17 (one of the seat members) used in the vehicle seat S of this embodiment, the gripping portion 19 grips the protruding portion 16a and covers the back surface, thereby suppressing the thickness of the protruding portion 16a. Therefore, when inserting the cushion pad 16 into the gap V, the worker can easily insert the protruding portion 16a of the cushion pad 16 into the gap V beyond the rear pipe 13b by simply pulling the extension portion 18 without holding the protruding portion 16a.
In addition, after inserting the protruding portion 16a into the gap V, the worker folds back the extension portion 18 on the rear pipe 13b and hooks the attachment portion 18c (wire member 18d) of the end portion 18b onto the claw portion 15c provided on the back surface of the pressure receiving plate 14a of the spring 14. This allows the cushion trim cover 17 and the cushion pad 16 to be attached to the cushion frame 1.

In this embodiment, as shown in FIG. 5, the thickness T1 of the extension 18 is formed to be thinner than the thickness T0 of the cover body 17a. By making the thickness T1 of the extension 18 thinner than the thickness T0 of the cover body 17a, the manufacturing cost can be reduced even if the extension 18 is made of the same material. In addition, when passing the extension 18 through the gap V, the thinner it is, the easier it is to pass through.

In addition, as described above, the extension portion 18 and the gripping portion 19 form the cylindrical body C, and the protruding portion 16a is passed through the inside of the cylindrical body C, which prevents the protruding portion 16a from moving in the sheet width direction, and allows the protruding portion 16a to easily pass through the gap V without shifting.

The front and left and right ends 17b of the cushion trim cover 17 are provided with mounting parts 17c for mounting the cushion trim cover 17 to the cushion frame 1 as shown in FIG. 4. The mounting parts 17c are realized by holding a wire member 17d at the end 17b of the cushion trim cover 17. The wire member 17d exposed from the cut-out portion at the end 17b is then hooked onto the claws 15a, 15b provided on the pair of cushion side frames 12 and the pan frame 11, thereby fixing the mounting parts 17c to the cushion frame 1.

The wire member 17d is preferably a metal or resin wire having a rod-like, linear, tubular shape, etc. The diameter of the wire member 17d is preferably 1 to 8 mm, and more preferably 1.5 to 5 mm.
The mounting portion 17c is formed by folding back the end portions 17b of the cushion trim cover 17 and sewing them together to form a bag shape, and then passing the wire member 17d through the bag and storing it therein. The wire member 17d is then hooked to the positions of the claw portions 15a, 15b formed on the cushion side frame 12 and the pan frame 11, which will be described later, to fix the cushion trim cover 17 to the cushion pad 16 with a predetermined tension.

As shown in FIG. 7, the cushion frame 1 is formed with multiple claws 15a, 15b for fixing the mounting portion 17c of the cushion trim cover 17. In this embodiment, the bottom surface of the pan frame 11 is formed with four claws 15a with an L-shaped cross section by cutting and raising, so that the mounting portion 17c provided at the front end of the cushion trim cover 17 can be hooked onto them.

Furthermore, two claws 15b having an L-shaped cross section are attached by welding to each of the left and right cushion side frames 12. Mounting portions 17c provided on the left and right ends of the cushion trim cover 17 are adapted to be hooked onto the claws 15b.
A claw portion 15c is formed by cutting and raising on the bottom surface of the pressure receiving plate 14a of the spring 14 provided on the cushion frame 1. A mounting portion 18c (wire member 18d) provided on the end portion 18b of the extension portion 18 folded back by the rear pipe 13b is hooked onto the claw portion 15c.

The cushion pad 16 covered with the cushion trim cover 17 is placed on the cushion frame 1, and the wire members 17d, 18d on the ends 17b, 18b are hooked onto the claws 15a-15c on the cushion frame 1 to fix the cushion pad 16 in place, making it easy to fix the cushion pad 16 to the cushion frame 1.

The manufacturing method of the vehicle seat S of this embodiment will be described with reference to FIG. 8. The seat frame F shown in FIG. 2 is prepared in advance, the back pad 26 is placed on the seat frame F, and the back trim cover 27 that covers the back pad 26 is attached (S101).

A cushion pad 16 having a protruding portion 16a at its rear end and a cushion trim cover 17 having an extension portion 18 and a grip portion 19 are prepared (S102). A cylinder C consisting of the extension portion 18 and grip portion 19 is turned upside down, the protruding portion 16a is passed through the turned-up cylinder C, and then the cylinder C is returned to its original state, and the protruding portion 16a is covered with the extension portion 18 and grip portion 19 (S103).

The cushion pad 16 covered with the cushion trim cover 17 is placed on the cushion frame 1, and the protruding portion 16a of the cushion pad 16, the extension portion 18 covering the protruding portion 16a, and the grip portion 19 are passed through the gap V between the rear pipe 13b and the seat back S2 (S104). After the protruding portion 16a is sandwiched between the rear pipe 13b and the seat back S2, the extension portion 18 of the cushion trim cover 17 is folded back by the rear pipe 13b, and the mounting portion 18c of the extension portion 18 is disposed on the bottom of the pressure receiving plate 14a.
Next, the wire members 17d, 18d of the mounting portions 17c, 18c provided at the ends of the cushion trim cover 17 are hooked onto the claw portions 15a to 15c provided on the cushion frame 1 and the pressure receiving plate 14a of the spring 14. The cushion pad 16 covered with the cushion trim cover 17 is attached to the cushion frame 1, and the vehicle seat S is completed (S105).

The vehicle seat and the manufacturing method thereof according to this embodiment have been described above with reference to the drawings. In the above embodiment, the seat cushion S1 having the protrusion 16a passing between the seat back S2 and the cushion frame 1 has been described. However, this is only one example, and the present invention may be applied to the seat back S2. That is, a protrusion extending downward may be provided at the lower end of the back pad 26 of the seat back S2, and the protrusion may be disposed between the lower frame 23 of the back frame 2 and the seat cushion S1. The protrusion is covered by an extension and a grip extending from the lower end of the back trim cover, so that the protrusion of the seat back S2 is not pressed when it is inserted, improving the workability of assembly.
