  • Publication number: 20110095585
    Abstract: The invention provides a vehicle seat device including fewer restrictions with respect to seat function and which can be switched from a seating position to a storage position by motive power. In a vehicle seat (10), a vehicle width direction outer side end portion of a seat cushion (12) is supported so as to be capable of rotating around a drive shaft (30) 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 (12) stands erect along a vehicle cabin inner side surface S, due to rotating around the drive shaft (30).

  • Patent number: 7753428
    Abstract: Disclosed is a vehicle seat device operating as follows. A retracting instruction is given by a seat switch to start operation of a seat back actuator. Lock of the seat back and a seat cushion is released to rotate the seat back to the position where it is overlapped with the seat cushion. A floor actuator is driven to release engagement between the floor panel and the floor lock. A lift up motor is operated to lift up the vehicle seat device toward the vehicle body. After this, a dragger lock motor is operated to lock a striker on the seat back rear surface and the dragger unit, thereby completing the retraction operation.
