[0046] Below, use Figure 1 to Figure 5 A first embodiment of a seat component according to the present invention and a vehicle seat using the seat component will be described. Arrow FR appropriately shown in these figures indicates the vehicle front side, arrow UP indicates the vehicle upper side, and arrow IN indicates the vehicle width direction inner side.

[0048] figure 1 is an exploded perspective view of a seat back corresponding to a backrest of a vehicle seat according to the present embodiment. Among them, in figure 1 In , the angles at which each component is observed are slightly changed and drawn. and, in Figure 4 A longitudinal sectional view of a vehicle seat including the seat back is shown in . As shown in these figures, the vehicle seat 10 has a seat cushion 11 on which an occupant sits (refer to Figure 4 ), a seat back 12 supported on the rear end of the seat cushion 11 in a tiltable manner, and a headrest (not shown) supported on the upp...

[0110] Next, use Figure 6 ~ Figure 8 A second embodiment of a seat component according to the present invention and a vehicle seat using the seat component will be described. However, the same reference numerals are assigned to the same components as those in the above-mentioned first embodiment, and description thereof will be omitted.

[0111] As shown in these figures, in this second embodiment, the side airbag device 130 uses an airbag device enlarged in the height direction of the seat back. Thus, in Image 6 as well as Figure 7 In the drawing, the side airbag device 130 is shown to be vertically longer than the side airbag device 100 of the first embodiment.

[0112] In addition, the basic structure of the seat back board 134 is the same as that of the seat back board 16 of 1st Embodiment. Therefore, the seat back board 134 includes the back board portion 36 and the back spring portion 38 constituted by the lower back spring portion 44 and the upper back spring por...

Abstract

Provided is a seat structural member and a vehicle seat using the same in which components of a reclining mechanism can be covered, a good-quality external appearance can be maintained in the vehicle seat, and the number of components can be reduced. An attachment part (102), which is formed in an L-shape when seen in plan view, is integrally formed with a lower coupling fixing part (50) provided at the outer side in the seat width direction of a resin seat backboard (16). A side airbag device (100) is attached to a lateral wall part (122) of the attachment part (102). A seat back pad and a cover are mounted onto the seat backboard (16) configured as described above, and are assembled with a seat back frame (14) and a side frame (26).

Description

technical field [0001] The present invention relates to a seat component and a vehicle seat using the seat component. Background technique [0002] Patent Document 1 below discloses a vehicle seat including a side airbag device that inflates and deploys a side airbag between a door trim of a side door and a side portion of a seated occupant upon a side collision. The side airbag device is usually built in a side portion of a vehicle seat on the outer side in the seat width direction. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-313302 [0004] However, in the case of a vehicle seat provided with a side airbag device as described in the above-mentioned prior art, the assemblability of the seat back may decrease. That is, the assembly of the seat back of a vehicle seat is generally performed by preparing a seat back frame assembly (subassembly) and a seat back cushion assembly in advance, and assembling the latter to the former in many cases. Here, the sea...
