Abstract: A vehicle seat includes a back frame connected to a base member so as to be able to rotate around a first rotation shaft; a rotation locking mechanism; a cushion frame connected to the back frame so as to be able to rotate around a second rotation shaft, and in which a long hole is formed; a link member connected to the base member so as to be able to rotate around a third rotation shaft; a fourth rotation shaft fixed to the link member and inserted in the long hole so as to be able to move relatively and so as to be able to rotate; and movement restricting portion provided between the fourth rotation shaft and an inner surface of the long hole, and that restricts movement of the fourth rotation shaft from one end portion of the long hole toward another end portion side.

Abstract: A vehicle seat includes a seat component member that has a frame member, a cushion material, and a support member arranged on the frame member. The support member includes a frame-shaped member having a polygonal shape that can be attached to the frame member, and a bag-shaped planar member that is attached to the frame-shaped member in a tensioned state to support the cushion material. The frame-shaped member can be accommodated in the bag-shaped planner member while at least one side of the frame-shaped member is at a contracted state. The frame-shaped member is maintained at an expanded state as the at least one side of the frame-shaped member is at a non-contracted state, such that the planner member is expanded from an inner side thereof and is maintained at the tensioned state.

Abstract translation: 车辆座椅包括具有框架构件，缓冲材料和布置在框架构件上的支撑构件的座椅构件构件。 支撑构件包括具有可附接到框架构件的多边形形状的框状构件和以张紧状态附接到框架构件以支撑缓冲材料的袋状平面构件。 框状构件可以容纳在袋形计划构件中，而框架构件的至少一侧处于收缩状态。 当框架构件的至少一侧处于非收缩状态时，框架构件保持在膨胀状态，使得规划器构件从其内侧膨胀并保持在张紧状态 。
