ABSTRACT:
An orientation-sensitive pressure release for the airbag (15) of a vehicular pneumatic seat (11) that includes a rollover valve (21) mounted in the air inlet line of the pneumatic seat is disclosed. The valve (21) releases air from the pneumatic seat (11) when the valve is tilted or overturned, which occurs when the vehicle is tilted or overturned. The valve includes a spring-loaded poppet (43) that encloses an exhaust port (41). Attached to the poppet is a downwardly extending whisker (65) that extends into an inverted conical cup (64). A conically shaped element (78) is affixed to the lower end of the whisker (65). Housed in the inverted conical cup is a relatively heavy ball (67). When the valve (21) is tilted or overturned, the ball (67) hits the side of the conically shaped element (78) causing the whisker (65) to tilt and the spring-loaded poppet (43) to open the exhaust port. Opening the exhaust port (41) releases air from the air bag (15).
