Abstract: A vehicle seat includes a seat cushion S1 and a seat back S2. The seat back S2 includes a seat back frame F2 constituting a framework thereof, a pressure-receiving member 30 located in the seat back frame F2 and designed to support an upper body of an occupant, elastically supporting members 26, 27 elastically supporting the pressure-receiving member 30 in the seat back frame F2, and a cover material covering the seat back frame F2 and the pressure-receiving member 30. The seat back is configured such that when a backward movement load is applied from the upper body of the occupant seated on the seat cushion S1 to the seat back S2, the pressure-receiving member 30 moves backward to allow the upper body of the occupant to sink into the seat back S2. A vibrating unit 50 is attached to the pressure-receiving member 30.

Abstract: Provided is a belt assist device having a compact configuration and being configured to move a seatbelt to an easily reachable position. A vehicle seat includes a belt assist device attached to a lateral portion of a seat back and configured to move a portion of a seatbelt placed on the lateral portion to the easily reachable position. The belt assist device includes a rotary member attached to a recessed housing portion of the lateral portion via a rotary shaft and configured to rotate up and down between a housing position at which the rotary member is housed in the seat back and a protruding position at which the rotary member rotates to protrude forward of the seat back to push out a portion of the seatbelt. The rotary member is disposed forward of a belt guide provided at the periphery of an upper end of the seat back.

Abstract: A vehicle seat device includes a rotating member rotatably supported by a base member via a rotary support part; a pressure receiving member supported by a seat cushion frame on the rotating member and receives the load of a seat cushion; and a rotary drive actuator that brings power for rotating the rotating member, wherein another actuator distinct from the rotary drive actuator is disposed to avoid a position overlapping with the rotary drive actuator in plan view. Thereby, the vehicle seat device can avoid increase in height even when another actuator is provided in addition to the rotary drive actuator.

Abstract: In a seat-rotating device that enables a seat to be rotated on a base member, a rattle-suppressing member operating in association with a lock member, which switches between the locked state in which rotation of an annular rotating member supporting a seat frame is prevented and release of the locked state, is in close contact with both a support member and the annular rotating member when the lock member is at the locked position, and a gap is created between the support member and the annular rotating member when the lock member attains the lock release position. Accordingly, it is possible to prevent the seat from rattling when it is in a stationary state and to facilitate rotation by releasing the rattle-preventing state when the seat is rotating.

Abstract: A rotating device for a vehicle interior item is provided with latching means that is provided on a side of a base member having a rotation support part, and engagement means that is provided on a side of a rotating member supporting a vehicle interior item and being rotatably supported by the rotation support part, and can be switched between a state in which the engagement means engages with the latching means so as to suppress detachment of the rotating member from the base member and a state in which the engagement with the latching means is released when the rotating member attains the rotatable state, wherein the latching means and the engagement means are disposed further outside than the rotating member in plan view at least when the rotating member is in the non-rotating state. Accordingly, it is possible to suppress an increase in the height while suppressing detachment when the vehicle interior item is not rotating.
