A vehicle seat comprising a horizontal seat cushion, a support shaft projecting upward from the seat cushion, and a rotatable backrest secured on the support shaft. The vehicle seat further comprises a mechanism for regulating the rotational movement of the backrest, which can be controlled in response to a detected driving state of the vehicle. The backrest may be immovably retained at a normal position relative to the seat cushion during the usual forward driving, and allowed to rotate to a suitable position during a stop, reverse, or cornering of the vehicle.

Vehicle seat with rotatable backrest

A device for moving up and down and tilting a headrest of a vehicle seat having a driven shaft for moving the headrest up and down and a support member for tilting the headrest. The drive shaft is operatively connected to leg members fixed to the headrest, and provided in a backrest of the vehicle seat. The support member is provided below the driven shaft. A drive mechanism drives the driven shaft to move the headrest up and down relative to the backrest, and a tilting mechanism rotates the leg members about the support member to tilt the headrest to a back of the seat backrest.
