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.
