<P>PROBLEM TO BE SOLVED: To improve protection performance for an occupant by rapidly and surely deploying an airbag body in a protection area behind a head rest. <P>SOLUTION: The airbag body 30 deploying between the head rest 40 and a back window glass 20 is stored in the upper part of the back surface side of a seat back 26, and the head rest 40 is attached to a seat back upper frame 34 swingably supported. The seat back upper frame 34 is provided with a pressure receiving plate 96 pressed and forwardly inclining the seat back upper frame 34 when the airbag body 30 is inflated. When the airbag body 30 is supplied with gas and inflated, the seat back upper frame 34 is forwardly inclined and the head rest 40 is moved forward. Thereby, a space T between the upper part of the head rest 40 and the back window glass 20 is widened, and the airbag body 30 can rapidly and surely be deployed in the protection area 64 behind the head rest. <P>COPYRIGHT: (C)2010,JPO&INPIT |
