<P>PROBLEM TO BE SOLVED: To provide an occupant crash protection device at a collision of a vehicle capable of efficiently reducing difficulties of a hip joint part, while relaxing stretching of legs of an occupant at the time of a front collision of the vehicle. <P>SOLUTION: This device is provided with a collision detection means 11 for detecting the front collision such as a head-on collision, an oblique collision and offset collision of the vehicle 1 and a hip joint part widening means 13 for widening an angle θ formed between the waist part Dw and the thigh part Dt of the occupant D sitting on a seat 12 by the detection of the front collision. When pressing force is inputted into the hip joint part of the occupant D via the legs at the time of the front collision, the load is inputted into a part having comparatively high rigidity from a thighbone via a thick part of the pelvis, and thereby high supporting rigidity against the pressing force can be obtained. Proof stress of the hip joint part therefore is improved to reduce the difficulties of the hip joint part. <P>COPYRIGHT: (C)2007,JPO&INPIT |
