Vehicle seat

[Problem] To reduce a driving force for expanding and contracting a seat in a vehicle seat. [Solution] A vehicle seat (1) comprises: a first frame (15); a second frame (16) supported so as to be movable relative to the first frame towards a first side and a second side opposite the first side; and an actuator (30) that moves the second frame relative to the first frame toward the first side and the second side. The actuator (30) includes: a first actuator (31) that pushes the second frame toward the first side; a second actuator (32) that urges the second frame toward the second side; and a control device (33) that controls the driving forces generated by the first actuator and the second actuator, respectively. Each of the first actuator (31) and the second actuator (32) includes a fluid bag (35, 36) to which and from which compressed air is supplied by the control device (33). 【问题】关于车辆座椅中，为了减小用于使座椅膨胀和收缩的驱动力。【方案】车辆座椅(1)包括：第一框架(15)；第二框架(16)，其被支承为相对于第一框架朝向第一侧和与第一侧相对的第二侧是可移动的；以及，致动器(30)，其使第二框架相对于第一框架朝向第一侧和第二侧移动
