Title: Occupant crash protection device
Inventor: SANO KOJI
IPC: B60R22/28
Filed: 2000-11-06
Abstract: PROBLEM TO BE SOLVED: To provide an occupant crash protection device capable of achieving a deceleration pattern effective in reduction of occupant deceleration with a simple structure. SOLUTION: At an initial stage of a vehicle body collision, a transmission member 10 transmits an impact force from a front side to a rear side independently from the vehicle body so that a part 3a near a seat belt 3 supporting part moves backward earlier than the deceleration generated in the seat part with a larger deceleration than the deceleration. A converting means converts the transmitted impact force to a force pulling the seat belt in order to pull the seat belt 3. Then, a shock absorbing means (a shock absorbing member 13) restrains the force for pulling the seat belt 3 so that the deceleration applied to the occupant almost corresponds with the deceleration generated on the seat part 2. Thus, the deceleration pattern effective in reduction of the occupant deceleration can be achieved.  Further, the actuation reliability is improved because this device is constituted only by a mechanical transmission structure without using an actuator wherein an electrical sensor or a propellant is used.
