Abstract
An apparatus (10) comprises an inflatable protection device (14) inflatable between the side structure (16) of a vehicle (12) and a vehicle occupant. The device (14) includes at least one inflatable front chamber (120), rear chamber (150), and middle chamber (100). The front chamber (120) and the rear chamber (150) each have an inflation fluid inlet (122 and 152) near an upper edge (50) of the device (14) and an inflation fluid outlet (124 and 154). The middle chamber (100) has at least one inflation fluid inlet (102, 104) near the lower edge (52) and is free from inlets near the upper edge (50). Inflation fluid enters the front and rear chambers (120 and 150) through the inlets (122 and 152) and exits through the outlets (124 and 154) into the inflation fluid inlets (102, 104) of the middle chamber (100) to inflate the middle chamber.
