Abstract: A vehicle seat is mounted on a floor in a laterally inwardly moveable manner, and is accelerated by a crash load input member, which is more rigid than the remaining part of the vehicle body, inwardly upon occurrence of a vehicle side crash. The vehicle occupant is firmly held to the seat. By thus appropriately controlling the time history of the lateral acceleration of the vehicle occupant at the time of a side crash, the maximum acceleration acting on the vehicle occupant can be controlled. The inward movement of the seat relative to the vehicle body provides a wider space between the vehicle occupant and door panel, and this contributes to the prevention of the injury to the vehicle occupant owing to the intrusion of the door panel into the passenger compartment at the time of a side crash.

The device comprises guide means that, during a change in motion of a vehicle, provide for a change in position of the seat in the form of translation and rotational movement of the seat in a generally backward direction opposite the direction of travel of the vehicle.

Abstract: As a moveable part of the vehicle body carrying a vehicle seat moves rearward under the action of an active or passive power source as a result of a vehicle crash, the seat belt which is anchored at the moveable part at one end and a fixed part of the vehicle body at another end is pulled rearward, and performs the function to apply a deceleration to the vehicle occupant in an early phase of the vehicle crash. This is followed by a slight slackening of the seat belt as the moveable part is subjected to a forward force. The active power source typically consists of a high pressure gas generating device, and a passive power source typically consists of a G control member which transmits the deceleration of a vehicle crash to the vehicle occupant from an early phase of the crash, and/or a stopper which applies a forward force to the moveable part as the moveable part moves rearward by a prescribed distance under the action of the power source.
