摘要： Load imparted to a seat back frame is stably absorbed and efficiently absorbed. In a vehicle seat 10, a weak portion 48 is formed by a fixing plate (50). The weak portion (48) continuously extends from an edge portion of a fixing hole (44) in the relative movement direction with respect to a hinge base bracket (40) of a fastening bolt. Thus the weak portion (48) presses against the fastening bolt when the hinge base bracket (40) rotationally moves about the axial line of a support hole (42). Moreover, when the weak portion (48) plastically deforms, deformation so as to press the weak portion (48) wider is suppressed, such that the weak portion (48) is deformed so as to be squashed. Consequently, load imparted to a seatback frame (64) can be stably absorbed by the weak portion (48). Moreover, due to the weak portion (48) continuously plastically deforming when the weak portion (48) is plastically deformed by the fastening bolt, the load imparted by the weak portion (48) to the seatback frame (64) can be efficiently absorbed.

摘要： In a vehicle seat (10), a deformable portion (32) extends continuously from an edge portion of a placement hole (28) towards an outside of the placement hole (28). When the deformable portion (32) is plastically deformed by a fastening bolt (40), the deformable portion (32) does not readily deform so as to be pushed outwards, but deforms so as to be squashed. When a low press-contact force acts on a side face (32D), the deformable portion (32) does not readily perform plastic deformation, and an impact load imparted to a seatback frame (44) can be stably absorbed by the deformable portion (32). Impact load imparted to the seatback frame (44) can be continuously absorbed by the deformable portion (32) since the deformable portion (32) deforms continuously. Accordingly, impact load imparted to the seatback frame (44) can be efficiently absorbed by the deformable portion (32).

摘要翻译： 在车辆座椅（10）中，可变形部分（32）从放置孔（28）的边缘部分朝着放置孔（28）的外部连续地延伸。 当可变形部分（32）由紧固螺栓（40）塑性变形时，可变形部分（32）不容易变形，从而被向外推动，而变形以便被挤压。 当低压力作用在侧面（32D）上时，可变形部分（32）不容易发生塑性变形，并且能够通过可变形部分（54）稳定地吸收向座椅靠背框架（44）施加的冲击载荷 32）。 由于可变形部分（32）连续变形，赋予座椅靠背框架（44）的冲击载荷可被可变形部分（32）持续吸收。 因此，能够通过可变形部（32）有效地吸收赋予座椅靠背框架（44）的冲击负荷。

摘要： A seat back has a seat back frame, a plane spring structure, and a headrest provided at the upper end of a seat back frame. The plane spring structure has left and right side wires, and horizontal wires extending in the horizontal direction. Connection wires are provided between the seat back frame and plane spring structure. First end portions and second end portions of the connection wires function as detachable portions. At least one of these detachable portions is detached from the seat back frame or plane spring structure by the load applied to the seat back, when a vehicle is bumped from behind.

摘要： The purpose of this invention is to simplify the structure for softening the shock of a rear-end collision. The lower portion of each of its right-side and left-side members 3, which are made of sheet steel, include a plurality of holes 7 and 8 in which fastening bolts 11 and 12 are inserted so as to connect the side members 3 with an external member. The fastening bolt 11 is capable of contacting the hole brim of a hole, and by installing such a fastening bolt 11 in all of the holes, or in all of the holes but one, the shock of a rear-end collision is softened.
