Problems solved by technology

[0003] Generally, the seat back of a vehicle seat is constructed by placing a cushioning material on a metal seat back frame and covering it with a skin material. The amount of deformation in this movement is not sufficient to effectively reduce the load on the passenger's body
Also, there is a concern that a huge load is applied to the seat back, thereby causing poor condition of the seat back

Embodiment ）

[0496] In each of the above-mentioned embodiments, in the form in which the restricting portion that restricts the amount of deformation of the deforming portion and other deforming portions is provided (specifically, the second to twelfth embodiments), the restricting portion is provided in several deforming portions, and only one of them is clamped. The position of the deformation part. For example, in the second embodiment, the restricting portion 40 sandwiching only a part of the inner fragile portion 17e has been described. However, it is not limited to this, it can also be Figure 69 and 70 As shown, a restricting portion 3140 is provided to clamp the hole portion 17k as the deformation portion, the inner fragile portion 17e and the side fragile portion 17m as other deformation portions. Figure 69 and Figure 70 It is a figure showing the modification example of the regulation part, Figure 69 is a brief stereogram, Figure 70 It is a brief floor plan.

Abstract

Provided is a vehicle seat which, when subjected to a complex input load during a rear collision, can stably deform at a specific portion thereof to efficiently absorb impact energy in the rear collision. A vehicle seat (S) is provided with: frame's side sections (15a, 17a) located at the left and right sides of a seat back frame (1) and extending in the vertical direction; and frame's extension sections (17b, 18) extending from the frame's side sections (15a, 17a) toward the inner side in the left-right direction. Deformable sections (17k) which deform when an impact load is applied are formed at connection sections (17x) connecting the frame's side sections (15a, 17a) and the frame's extension sections (17b, 18). The deformable sections (17k) are formed adjacent to other deformable sections (17m, 17e) having different degrees of susceptibility to deformation.

Description

technical field [0001] The present invention relates to a vehicle seat, in particular to a vehicle seat capable of stably absorbing impact energy in a rear collision. Background technique [0002] Generally, when a vehicle such as an automobile is rear-end hit or receives a large collision while driving in reverse, that is, in a rear collision, the occupant may move backward rapidly due to inertia, and the upper body of the occupant may lean backward. [0003] Generally, the seat back of a vehicle seat is constructed by placing a cushioning material on a metal seat back frame and covering it with a skin material. The amount of deformation in this operation is not sufficient to effectively reduce the load on the passenger's body. Also, there is a concern that a huge load is applied to the seat back, thus causing poor condition of the seat back. [0004] In order to solve such a problem, in Patent Document 1, it is proposed that when a rearward load is applied to the upper p...
