A vehicle seat device in which a seat can be simply and reliably held at a storage position. In a vehicle seat, a vehicle width direction outer side end portion of a seat cushion is supported so as to be capable of rotating around a drive shaft having an axis along a vehicle front-rear direction, and the seat cushion can be switched between a seating configuration at which an occupant can be seated and a storage configuration at which the seat cushion stands erect along a vehicle cabin inner side surface, due to being rotated around the drive shaft by a driving motor. Further, the vehicle seat which is in the storage configuration is held at the storage configuration by a striker.

Vehicle seat device

A striker is supported by and coupled to a seat body and is held in a rotated position where the striker is lowered to a position along the shape of the seat body. When the seat body is moved and stowed, the striker is raised to and held at a rotated and raised position where the striker can be engaged and locked to a locking device. Elasticity of an opening spring and a rubber body, which are arranged between the striker and a coupling section, allows a forced rotational displacement of the striker in both forward and reverse directions from a state in which the striker is held at the rotated and raised position.

Lock structures for stowable vehicle seats

A cable wiring structure of a vehicle seat is provided including a headrest attached to a seat-back, a skin member covering the seat-back, a cable extending in the seat-back, a wire member extending between sides of a frame, and a strip member attached to the wire member. When the cable is pulled and the headrest is moved to a seat front side, the cable is moved to extend through a guiding recess portion formed in a portion of the wire member and a portion of the skin member is pulled into the seat-back as the portion of the skin member is extended by the strip member over the guiding recess portion.

An engine output shaft drives an engine driven pump. The engine driven pump pressurizes oil. An accumulator accumulates the pressurized oil. An electric motor drives a motor driven pump. When the engine rotates low speed, both the engine driven pump and the motor driven pump supply oil to an oil chamber of a belt type continuously variable transmission. If it is required to enlarge a capacity of the oil chamber quickly, the pressurized oil in the accumulator is supplied to the motor driven pump. The motor driven pump further pressurizes the pressurized oil in the accumulator and supplies it into the oil chamber. It is possible to supply a sufficient amount of oil to the continuously variable transmission. Additionally, since the system may be constructed by using a small type engine driven pump, it is possible to improve fuel efficiency.
