摘要:
An apparatus (10) helps protect an occupant (20) of a vehicle (12). The apparatus (10) includes an inflatable vehicle occupant protection device (14). The protection device (14) includes a first chamber (166) inflatable between a thorax (122) of the occupant (20) and a side structure (16) of the vehicle (12). The protection device (14) also includes a second chamber (162) inflatable between a head (100) of the occupant (20) and the side structure (16) of the vehicle (12). The apparatus (10) further includes an inflation fluid source (22) for inflating the first chamber (166) to a first pressure and for inflating the second chamber (162) to a second pressure that is greater than the first pressure.
