Abstract: In a vehicle seat, a second parallel link mechanism is actuated in order to adjust an vertical position of a seat body with respect to a vehicle body, such that a first parallel link mechanism is moved up or down together with the seat body with respect to the vehicle body. In order to recline a seatback as an integral unit with a seat cushion, the first parallel link mechanism and the second parallel link mechanism are actuated such that an upper link is maintained in a predetermined orientation. The upper link is restricted from rotating relative to the armrest, and so the armrest is also maintained in a predetermined orientation.

Abstract: A vehicle seat device comprises: a seat disposed at a vehicle width direction inner side of a side door of a vehicle; a rotating mechanism that rotates the seat about a vertical axis relative to a vehicle body; a sideways movement mechanism that moves the seat in a vehicle width direction relative to the vehicle body between a normal region and an inner region; and a control device which, when causing the rotating mechanism to rotate the seat, causes the sideways movement mechanism to move the seat from the normal region to the inner region before the rotation.

Abstract: A power seat device is configured to acquire a target associated position of a tilted position, corresponding to a current position of a seatback for allowing the seatback to reach an end position in a reclining range, and a seat to reach an end position in a tilting range simultaneously. Outputs of a reclining motor and a tilting motor are adjusted so that the tilted position coincides with the acquired target associated position.
