Vehicle occupant side crash protection system
First Claim
1. A vehicle occupant protection system, comprising:
- a seat fitted with a seat belt for restraining a vehicle occupant and laterally moveably supported by a floor, said seat belt having two ends attached to the seat;
a crash load input member having a higher rigidity than an adjacent side panel of the vehicle body, the crash load input member being connected to the seat and having one end extending to a part adjacent to a side sill; and
brake means for applying an opposite force to the seat after it has traveled a certain distance toward the central part of the vehicle body, wherein the seat is provided with a restraining member for restraining the vehicle occupant from moving laterally outwardly with respect to the vehicle body and further wherein the restraining member comprises an extension of a seat back extending forward from an outboard side thereof.

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.

5. A vehicle occupant protection system, comprising:
-
a seat fitted with a seat belt for restraining a vehicle occupant and laterally moveably supported by a floor, said seat belt having two ends attached to the seat;
a crash load input member having a higher rigidity than an adjacent side panel of the vehicle body, the crash load input member being connected to the seat and having one end extending to a part adjacent to a side sill; and
brake means for applying an opposite force to the seat after it has traveled a certain distance toward the central part of the vehicle body, wherein the crash load input member has an inboard end attached to the seat and an outboard end located at a side part of the vehicle body where an impact from a side crash is substantially directly transmitted. wherein the crash load input member is slidably supported by the floor, and wherein the crash load input member is slidably supported by the lower surface of the floor.
