Japanese Utility Model Publication No. 61-045895

However, as shown in FIG. 7A, the suspension method using the C-ring 100 has a problem that a predetermined cushion pad thickness is required at the bottom of the suspension groove.
This makes it difficult to reduce the thickness of the vehicle seat.
Further, as shown in FIG. 7B and FIG. 5 of Patent Document 1, according to the method of hanging with the pulling cloth 300, the hanging depth becomes unstable due to the rigidity of the cushion pad and the hanging rigidity. There was a problem with.
In other words, if the cushion pad has a low rigidity (hardness), the cushion pad will be deformed when suspended, and the suspended depth will become unstable, or the latch at the suspension destination will be easier to move. There was a problem.
Furthermore, according to the technique described in Patent Document 1, the insert member can be easily suspended by engaging the receiving member disposed on the surface of the cushion pad. Since the film is positioned on the surface and is positioned by the film, it has been desired to realize stronger mounting rigidity.
In other words, in the prior art, there are a problem of suspension rigidity, a problem that it is difficult to apply to thinning of a vehicle seat, a problem that a suspension operation is complicated, and the like.
There is also a problem that the fixed position is not stable.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vehicle seat in which the fixing position of the suspension portion is stable and the suspension rigidity is high.
Another object of the present invention is to provide a vehicle seat that can cope with a reduction in thickness and has good operability.

According to the vehicle seat of claim 1, the subject is a vehicle seat comprising at least a cushion pad disposed on a skeleton of the vehicle seat and a seat cover that covers the cushion pad, A locked member is fixed to a surface of the cushion pad that is far from the surface on which the seat cover is disposed, and behind the groove formed between the adjacent cushion pads. The locking member is fixed to the cushion pad so as to bridge two opposing side surfaces of the adjacent cushion pad, and a part of the seat cover is suspended from the groove portion and fixed to the locked member. and is said to be the locking member has a through hole and has at least one slit is formed in the slit, the distance in the direction orthogonal to the longitudinal direction of the groove There slit width, the in the through hole, wherein is solved by being configured to be larger than the through-hole width is the distance in the direction orthogonal to the longitudinal direction of the groove.

Thus, according to this invention, the to-be-latched member is being fixed to the cushion pad in the surface side far from the surface side in which a seat cover is arrange | positioned in a cushion pad.
For this reason, the fixing position of the suspension part is stabilized and the locked member is fixed to the cushion pad, so that the suspension rigidity is increased and the force applied in the direction of coming out of the suspension groove is applied. Generation | occurrence | production of the movement (position shift | offset | difference) etc. of a locking member can be suppressed effectively.
In addition, since a predetermined cushion pad thickness is not required at the bottom of the hanging groove as in the prior art, it is possible to reduce the thickness and to suspend a part of the seat cover on the locked member. Since it can be fixed with, the workability of hanging is improved.
Further, the locked member is formed with a through hole and at least one slit, and in the slit, a slit width which is a distance in a direction intersecting with a longitudinal direction of the groove is in the through hole. If it is configured to be larger than the width of the through hole that is the distance in the direction intersecting the longitudinal direction of the groove portion, the locked member can be more stably attached.

At this time, as described in claim 2, if the locked member is configured to be integrally formed with the cushion pad, a force in the direction of coming out of the hanging groove is further applied. This is preferable because the movement (positional deviation) of the locked member at the time is suppressed.

Moreover, at this time, as described in claim 5 , when the slit is formed in two, and the through hole is formed between the two slits, the locked member and the cushion pad Since the suspension can be performed at a location sandwiched between the parts having a high mounting rigidity, the suspension rigidity of the seat cover is improved.

More specifically, as in claim 6 , the locking member includes a seat mounting portion that is attached to an end portion of the seat cover, and a locking piece that is locked to the locked member. The locking piece is formed at the connecting portion extending from the seat mounting portion toward the locked member, and at the locked member side end of the connecting portion. An insertion locking portion having an arrow-shaped cross section, and the insertion locking portion extends outward from the connecting portion and then moves inward as it approaches the locking member direction. And a corner formed by the connecting portion and a portion extending outward from the connecting portion is at least one of the outer peripheral edges of the through hole. The seat cover is suspended by being locked to the portion.

With this configuration, the locking member can be easily passed through the through-hole, and can be reliably locked at the corner.
The triangle having the cross-sectional shape of an arrowhead is, for example, two symmetrical with respect to a median line (a median line passing through the apex constituting the apex angle) with the apex angle directed downward and extending in the depth direction of the hanging groove. It may be an equilateral triangle or an arrowhead-shaped triangle formed by one right triangle divided into two with respect to the midline.
In other words, it is only necessary that the width is reduced (that is, sharpened) as it goes down in the direction of the locked member. With such a configuration, the operation of inserting the insertion locking portion into the through hole is easy. become.

Further, specifically, as in claim 7 , the insertion locking portion has an isosceles triangle shape in which the apex angle is disposed at a position close to the locked member, and the apex angle is It is preferable that a slit-like space cut in the depth direction of the groove is formed.
With this configuration, when the insertion locking portion is inserted into the through hole, the slit-shaped space is narrowed to facilitate passage, and after passage, the space is restored to its original by a restoring force. The locking rigidity is improved by returning to the width.
Therefore, the suspending workability is improved and the suspending rigidity can be increased.

Further, as in claim 8 , when a part of each side surface facing the locked member enters into one slit in the adjacent cushion pad, the mounting of the mounted member is more stable. Is preferable.
That is, since it is comprised so that both the adjacent cushion pads can be fixed in a single slit (between the hanging grooves), more stable attachment can be achieved.

According to the present invention, the fixed position of the suspended portion is stabilized, the suspended rigidity is increased, and the movement (positional deviation) of the locked member when a force is applied in the direction of coming out of the suspended groove, etc. Generation can be effectively suppressed.
In addition, it is possible to cope with a reduction in thickness, and the suspending workability is improved.
According to the present invention, movement (positional deviation) of the locked member when a force in the direction of coming out of the hanging groove is applied is suppressed.
According to the present invention, the seat cover is easily suspended in the suspension groove that is difficult to visually confirm.

  As shown in FIG. 1, the vehicle seat S according to the present embodiment includes a seat back S1, a seat cushion S2, and a headrest (headrest fixing portion S3) (not shown).

The overall structure of the vehicle seat S will be briefly described with reference to FIG.
Although illustration is omitted, a seat frame serving as a skeleton is provided in the vehicle seat S. The seat frame includes a seat back frame that is a frame of the seat back S1 and a seat cushion frame that is a frame of the seat cushion S2. The seat cushion frame and the seat back frame are connected via a reclining mechanism. A cushion pad K1 and a seat cover K2 are disposed outside the seat back frame and the seat cushion frame, and the seat back S1 and the seat cushion S2 are configured by these.

  The headrest (not shown) is a known headrest, and is fixed to a headrest fixing portion S3 formed on the upper portion of the seat back frame, and supports the head of the occupant above the seat back S1.

The structure of the suspension unit 1 according to the present embodiment will be described with reference to FIG.
A trim cord K21 is disposed at the end of the seat cover K2 so as to cover the end side.
The suspension unit 1 according to the present embodiment includes a clip 11 and a plate 12.
The clip 11 includes a sheet gripping portion 11A and a plate locked portion 11B.

The sheet gripping portion 11A is formed in a substantially U-shaped cross section having an opening at the top.
That is, it has a substantially rectangular flat plate-like bottom portion 11a and gripping claws 11b and 11b formed in a substantially L-shaped cross section standing upward from two opposite sides of the bottom portion 11a.
The gripping claw 11b is formed in a substantially L-shaped cross section by a rising portion 111 rising from the bottom portion 11a and a gripping end portion 112 that is bent and extended approximately 90 ° inward from the upper end portion of the rising portion 111.

The rising portions 111 and 111 are arranged in parallel to face each other in the horizontal direction, and extend so that the free ends of the grip end portions 112 and 112 are disposed inward.
That is, it extends so that the free ends of the grip ends 112 and 112 approach each other.

The distance t1 between the rising portions 111 and 111 is configured to match the width of the trim cord K21, and the distance t2 between the grip end portions 112 and 112 is smaller than the width of the trim cord K21. (Preferably so as to match the thickness of the seat cover K2).
With this configuration, the seat cover K2 above the trim cord K21 can be sandwiched between the grip end portions 112 and 112 in a state where the trim cord K21 is disposed between the rising portions 111 and 111.

Further, the plate locked portion 11B is configured to include locking pieces 11c and 11c.
The locking piece 11c is a portion that rises downward from the bottom portion 11a (on the side opposite to the side where the rising portion 111 rises), and includes a connecting portion 113 and an insertion locking portion 114.
The connecting portion 113 is a rectangular flat wall portion that rises downward from the bottom portion 11a (the side opposite to the side where the rising portion 111 rises), and the insertion locking portion 114 is formed on the lower end side of the connecting portion 113. It is an arrow tip-shaped portion having a substantially triangular cross section.

In other words, the insertion locking portion 114 extends from the lower portion of the connecting portion 113 in the outward direction, and then extends from the outermost portion of the extended portion toward the lowermost portion disposed on the inner side of the portion. It is formed in the shape of an arrowhead.
A corner portion formed by the connecting portion 113 and a portion extending outward from the connecting portion 113 is referred to as “corner corner portion D”.

In the present embodiment, the locking pieces 11c and 11c are arranged in parallel with a predetermined interval t3, and the insertion locking portions 114 and 114 are symmetrical with respect to the vertical midline. It is arranged to become.
That is, the insertion locking portions 114 and 114 are configured such that the width is narrowed downward and the cross-section is an arrow tip shape.

The plate 12 according to the present embodiment is a substantially rectangular flat plate, and a clip locking hole 12a drilled in a substantially rectangular shape is formed at the center thereof.
The plate 12 is formed with two molding holes 12b and 12b which are formed in a substantially rectangular shape so as to sandwich the clip locking hole 12a.
The forming hole 12b is formed such that the long side extends in a direction substantially perpendicular to the longitudinal direction of the clip locking hole 12a.

Next, a method of using the suspension unit 1 will be described with reference to FIGS.
The plate 12 is integrally insert-molded when foam-molding the cushion pad K1 at each hanging position (see FIG. 4).
In the present embodiment, as shown in FIG. 5, insert molding is performed at a position along the inner surface of the cushion pad K1 (that is, the surface side opposite to the surface on which the seat cover K2 is disposed).
At this time, the cushion material constituting the cushion pad K1 is molded in a state of entering the molding holes 12b and 12b formed in the plate 12, and thus the fixing rigidity between the cushion pad K1 and the plate 12 is improved. To do.

In this example, the clip locking hole 12a is formed at a position sandwiched between the molding holes 12b and 12b.
For this reason, since the suspension can be performed at a position where the attachment rigidity to the cushion pad K1 is high, the suspension rigidity is improved.

Further, as shown in FIG. 4, the cushion pad K1 is configured by combining a plurality of cushion pad pieces K11, and the suspended position where the plate 12 is disposed is the distance between the adjacent cushion pad pieces K11 and K11. It is a boundary part.
That is, a space called “hanging groove G” is formed between the adjacent cushion pad pieces K11 and K11, and the seat cover K2 is hung in the hanging groove G.
Therefore, in this example, the plate 12 is disposed so as to straddle the hanging groove G.

In other words, it is disposed so as to bridge two side walls (the gap between the two side walls becomes the hanging groove G) where the phases of the adjacent cushion pad pieces K11 and K11 are opposed to each other.
At this time, the clip locking holes 12a formed in the plate 12 are arranged so that the hanging groove G runs along the direction (that is, the longitudinal direction runs along the running direction of the hanging groove G).
Thereby, the enlargement of the hanging groove part G can be suppressed effectively.

First, as shown in FIG. 3, the clip 11 is attached to the trim cord K21 by locking the trim cord K21 to the rising portions 111, 111.
Next, the seat cover K2 is suspended to the position where the plate 12 is fixed by press-fitting and engaging the insertion locking portions 114, 114 constituting the clip 11 into the clip locking holes 12a formed in the plate 12. Can be included.

That is, as described above, the space of the interval t3 is interposed between the locking pieces 11c and 11c.
Therefore, when the insertion locking portions 114 and 114 are press-fitted into the clip locking holes 12a of the plate 12, the insertion locking portions 114 and 114 apply a pressing force inward from the longitudinal inner wall portion of the clip locking holes 12a. Accordingly, the interval t3 is narrowed, and the clip locking hole 12a can pass from the upper side to the lower side.

When the insertion locking portions 114 and 114 pass through the clip locking hole 12a, the pressing force that the insertion locking portions 114 and 114 received from the inner wall portion in the longitudinal direction of the clip locking hole 12a is released. The distance between the insertion locking portions 114 and 114 is restored to the interval t3 by force.
For this reason, as shown in FIG. 5, the insertion locking portions 114 and 114 are locked to the back side of the clip locking hole 12 a by the entering corner portion D.

Thus, according to the present embodiment, by using the clip 11, the seat cover K2 can be easily suspended to the fixing position of the plate 12.
Further, since the clip locking hole 12a is a through hole, the hanging work can be easily performed even in the hanging groove G that is difficult to visually confirm.
At this time (see FIG. 5), the tip end portion of the clip 11 (that is, the insertion locking portions 114 and 114) penetrates the cushion pad K1 inside the plate 12.
That is, since the clip locking hole 12a is used as a through hole and the insertion locking portions 114, 114 of the clip 11 are penetrated, visual confirmation can be made during the work, and the mounting workability is improved.

Further, because of such a configuration, the removal work of the clip 11 can be assisted by pushing back the insertion locking portions 114 and 114 toward the plate 12 side.
Therefore, workability such as replacement of the clip 11 is improved.
During normal use, the cushion pad inside is a closed space, so unnecessary force is not applied to the location, and the configuration does not affect the suspended state.

Next, a modified example will be described with reference to FIG.
In the modified example, the shape of the clip 11 is different.
FIG. 6A shows an example in which the locking piece 11c has only one shape as compared with the previous example.
In the case of this configuration, the insertion locking portion 114 may be made of a material having elasticity to some extent (to the extent that it can pass through the clip locking hole 12a).
Moreover, it is good also as a structure made into the notch formed in the edge part, without using the clip latching hole 12a of the plate 12 as a hole.

FIG. 6B shows an example in which the gap between the locking pieces 11c and 11c is eliminated.
Also in this configuration, it is preferable that the insertion locking portion 114 be made of a material having elasticity to some extent (to the extent that the clip locking hole 12a can be passed).
Moreover, it is good also as a structure made into the notch formed in the edge part, without using the clip latching hole 12a of the plate 12 as a hole.
