Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when the buckle is passed through the buckle storage portion, if the rubber band and the buckle are arranged in a positional relationship different from the defined positional relationship, it is conceivable that the fall of the buckle from the buckle storage recess cannot be suppressed. That is, in the configuration described in the above Patent Document 1, there is room for improvement from the viewpoint of suppressing mis-assembly when passing the buckle through the buckle storage portion.

[0005] In consideration of the above facts, an object of the present invention is to obtain a vehicle seat capable of suppressing mis-assembly when passing a buckle through a buckle storage portion.

Means for Solving the Problems

[0006] The first embodiment of a vehicle seat comprises a seat cushion that supports the buttocks of a seated occupant from below the seat, a buckle storage section formed in the seat cushion and which houses a buckle, and a band fixed to the seat cushion within the buckle storage section, stretched between two locations on the inner surface of the buckle storage section, and supporting the buckle between itself and the inner surface of the buckle storage section to restrict the buckle from falling downwards towards the seat, wherein the buckle is configured to prevent it from falling downwards towards the seat, whether it is positioned on one side of the band within the buckle storage section or on the other side of the band.

[0007] In the first embodiment of the vehicle seat, whether the buckle is positioned on one side relative to the band within the buckle storage compartment or on the other side relative to the band, the buckle can be supported between the inner surface of the buckle storage compartment and the band, thereby preventing the buckle from falling downwards on the seat. In this configuration, the buckle may be passed through either one side or the other side relative to the band within the buckle storage compartment. This helps to prevent incorrect assembly when passing the buckle through the buckle storage compartment.

[0008] In the second embodiment of the vehicle seat, the band is stretched diagonally across the buckle storage portion when viewed from above the seat, as in the vehicle seat of the first embodiment.

[0009] In the second embodiment of the vehicle seat, the band is stretched diagonally across the rectangular buckle storage compartment. In this configuration, the space within the rectangular buckle storage compartment can be more uniformly divided into two by the band. [Effects of the Invention]

[0010] The vehicle seat according to the present invention has the excellent effect of suppressing incorrect assembly when passing the buckle through the buckle storage section. [Brief explanation of the drawing]

[0011] [Figure 1] This is a plan view of the seat cushion, seen from above. [Figure 2] This is a magnified view of the portion of the seat cushion where the buckle storage area is formed. [Figure 3] Figure 1 is a side cross-sectional view showing a cross-section of the seat cushion cut along line AA, with the buckle threaded through the band on the left side. [Figure 4] This is a side cross-sectional view corresponding to Figure 3, showing the buckle being threaded through the band on the right side. [Modes for carrying out the invention]

[0012] A vehicle seat according to an embodiment of the present invention will be described with reference to Figures 1 to 4. In the figures, arrow FR indicates the front side of the vehicle seat, arrow UP indicates the upper side of the seat, arrow RH indicates the right side in the seat width direction, and arrow LH indicates the left side in the seat width direction. Furthermore, in the following description, unless otherwise specified, when the front / rear, up / down, and left / right directions are indicated, they refer to the front / rear direction of the seat, the up / down direction of the seat, and the left / right direction in the seat width direction.

[0013] Figures 1, 2, and 3 show a seat cushion 12 that constitutes part of the vehicle seat 10 of this embodiment. The seat cushion 12 comprises a cushion frame 14 that constitutes the framework of the seat cushion 12, and a seat cushion body 16 attached to the cushion frame 14.

[0014] The seat cushion body 16 is composed of a cushion pad 18 made of urethane foam or the like, a surface material 20 that covers the cushion pad 18, and a band 22 fixed to the surface material 20.

[0015] The cushion pad 18 comprises a main portion 24 that forms the middle part of the cushion pad 18 in the left-right direction and is positioned opposite the seated occupant's buttocks in the vertical direction, and a pair of left and right side portions 26 that form the left and right sides of the cushion pad 18. A buckle storage hole 28 is formed at the rear of the left side portion 26, adjacent to the main portion 24, and penetrates the cushion pad 18 in the vertical direction. When viewed from above, the shape of this buckle storage hole 28 is rectangular (longitudinal) with the front-to-back direction as its longitudinal direction. The buckle storage hole 28 may also be configured not to penetrate the cushion pad 18 in the vertical direction.

[0016] The outer material 20 is formed by sewing together multiple pieces of fabric or synthetic leather cut into a predetermined shape. The outer material 20 includes a main section covering portion 30 that covers the surface of the main section 24, a side section covering portion 32 that covers the surface of the side section 26, and a storage hole covering portion 34 that covers the inner surface of the buckle storage hole 28. The front portion 34A, the rear portion 34B, the right portion 34C, and the left portion 34D of the storage hole covering portion 34 cover the front, rear, right, and left sides of the inner surface of the buckle storage hole 28 of the cushion pad 18, respectively. The buckle storage portion 38, in which the buckle 36 that constitutes part of the seat belt device is stored, is formed by the buckle storage hole 28 of the cushion pad 18 and the storage hole covering portion 34 of the outer material 20.

[0017] The band 22 is, as an example, a rubber band formed in a ribbon shape and can be stretched in its longitudinal direction. This band 22 is provided on the lower side within the buckle storage portion 38. Also, one end of the band 22 is fixed by sewing or the like at the boundary portion between the right end of the front portion 34A of the storage hole covering portion 34 and the front end of the right portion 34C. Further, the other end of the band 22 is fixed by sewing or the like at the boundary portion between the left end of the rear portion 34B of the storage hole covering portion 34 and the rear end of the left portion 34D. Thereby, the band 22 is stretched diagonally within the rectangular buckle storage portion 38.

[0018] (Operations and Effects of the Present Embodiment) Next, the operations and effects of the present embodiment will be described.

[0019] As shown in FIGS. 1, 2, and 3, in the vehicle seat 10 of the present embodiment described above, when the buckle 36 is passed (inserted) through the left space with respect to the band 22 within the buckle storage portion 38, the buckle 36 is supported between the inner surface of the buckle storage portion 38 and the band 22. Thereby, the fall of the buckle 36 downward can be restricted.

[0020] On the other hand, as shown in FIGS. 1, 2, and 4, when the buckle 36 is passed (inserted) through the right space with respect to the band 22 within the buckle storage portion 38, the buckle 36 is supported between the inner surface of the buckle storage portion 38 and the band 22. Thereby, the fall of the buckle 36 downward can be restricted.

[0021] As described above, in the vehicle seat 10 of the present embodiment, in either the case where the buckle 36 is disposed on the left side with respect to the band 22 in the buckle storage portion 38 and the case where it is disposed on the right side with respect to the band 22, the buckle 36 can be supported between the inner surface of the buckle storage portion 38 and the band 22 to limit the fall of the buckle 36 downward. In this configuration, the buckle 36 may be passed through either the left side or the right side with respect to the band 22 in the buckle storage portion 38. Thereby, it is possible to suppress mis-assembly when passing the buckle 36 through the buckle storage portion 38.

[0022] Also, in the vehicle seat 10 of the present embodiment, the band 22 is stretched diagonally in the rectangular buckle storage portion 38. In this configuration, the space in the rectangular buckle storage portion 38 can be more uniformly divided into two by the band 22.

[0023] Note that, in the present embodiment, an example in which the band 22 is stretched diagonally in the rectangular buckle storage portion 38 has been described, but the present invention is not limited thereto. The routing of the band 22 in the buckle storage portion 38 may be appropriately set in consideration of the shape of the buckle storage portion 38 and the like.

[0024] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above, and it is needless to say that various modifications other than the above can be implemented without departing from the gist thereof.
