摘要： A vehicle seat that may assure stiffness of a seatback and that may realize a reduction in weight. In the present rear seat for a vehicle, a substantially X-shaped X-rib (24) is joined to a panel frame (22) of a rear seatback. A first reinforcement portion (24A) of the X-rib (24) spans in a linear shape between an anchor wire (68), which is a point of action of a load, and a first supported portion (22A) of the panel frame (22), which is supported at a vehicle body via a turning hinge (48). A second reinforcement portion (24B), which has a length direction middle portion in common with the first reinforcement portion (24A), spans in a linear shape between a second supported portion (22B) of the panel frame (22), which is supported at the vehicle body via a turning hinge (56), and a third supported portion (22C) of the panel frame (22), which is supported at the vehicle body via a lock mechanism (64).

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： 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： The time until a headrest contacts the head of an occupant in the event of a rear collision is shortened with a simple configuration. In a seat device, a stay (46) (including grommets (22)) is set with bending rigidity towards the vehicle front lower than the bending rigidity towards the vehicle rear. Accordingly, when the headrest oscillates in the event of a vehicle rear collision, the headrest is initially displaced towards the vehicle rear, however the headrest changes direction in a short time and begins to be displaced towards the vehicle front. Moreover, there is a large displacement of the headrest towards the vehicle front since the stay (46) (including the grommets (22)) has a lower bending rigidity towards the vehicle front than the bending rigidity towards the vehicle rear. The time until the headrest contacts the head (H) of the occupant can accordingly be shortened. The headrest can be promptly displaced towards the side of the head (H) of the occupant due to setting the bending rigidity of the stay (46) including the grommets (22), thereby enabling the time until the headrest contacts the head of the occupant to be shortened with a simple configuration.
摘要翻译： 在后部碰撞的情况下头枕接触乘员头部的时间以简单的配置缩短。 在座椅装置中，将停留物（46）（包括索环（22））设置成朝向车辆前方的弯曲刚度低于朝向车辆后部的弯曲刚度。 因此，当在车辆后方碰撞的情况下头枕振荡时，头枕首先朝向车辆后方移动，然而头枕在短时间内改变方向，并开始向车辆前方移动。 此外，由于停留（46）（包括索环（22）），朝向车辆后方的弯曲刚性具有朝向车辆前方的较低的弯曲刚性，所以头枕朝向车辆前方具有大的位移。 因此可以缩短头枕接触乘员头部（H）的时间。 由于设置包括索环（22）的支柱（46）的弯曲刚度，头枕可以迅速地朝向乘员的头部（H）的位置移位，从而能够直到头枕接触乘员头部 以简单的配置缩短。

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.
摘要翻译： 赋予座椅靠背框架的载荷被稳定地吸收并被有效地吸收。 在车辆座椅10中，弱部48由固定板（50）形成。 弱部（48）相对于紧固螺栓的铰链基座支架（40）在相对移动方向上从固定孔（44）的边缘部分连续延伸。 因此，当铰链基座托架（40）围绕支撑孔（42）的轴线旋转移动时，弱部分（48）压靠紧固螺栓。 此外，当弱部（48）塑性变形时，抑制使弱部（48）更宽的变形，使得弱部（48）发生变形而被挤压。 因此，能够通过弱部（48）稳定地吸收施加到座椅靠背框架（64）的负荷。 此外，由于当弱部（48）被紧固螺栓塑性变形时，弱部（48）连续塑性变形，所以可以有效地吸收由弱部（48）施加到座椅靠背框架（64）的负载。

摘要： A supporting member in a conventional seat device is supported only by torsion bar arm portions positioned at right and left sides of the device. Accordingly, when a large biased load acts on the device, a sufficient roll rigidity is not obtained and both arm portions at the right and left sides rotate simultaneously. Interference with the supporting panel, cushion frame or the like may also occur. Accordingly, a seat pad supporting member supported by a cushion frame provided on a floor is elastically supported on at least one of the front and rear portions thereof to a torsion frame by a torsion bar. The torsion bar is latched, at the torsion bar torque bar portion side, to the cushion frame side. The torsion arm portion side, moreover, is latched to the right and left sides. Finally, the torsion bar arm portion, on both sides, is connected to a connecting member.
摘要翻译： 常规座椅装置中的支撑构件仅由位于装置的左侧和右侧的扭杆臂支撑。 因此，当大的偏置负载作用在装置上时，不能获得足够的辊刚度，并且左右两侧的臂部同时旋转。 也可能发生与支撑面板，缓冲框架等的干扰。 因此，由设置在地板上的缓冲框架支撑的座垫支撑构件通过扭杆在其前后部分中的至少一个上弹性支撑到扭力框架。 扭杆在扭杆扭矩杆部分侧锁定到缓冲框架侧。 此外，扭转臂部侧被锁定在左右两侧。 最后，两侧的扭杆臂部连接于连接部件。
