<p>An air bag device is made of a reservoir (1) of fluid sealed by a frangible plate (3), and a cushion (2) connected to the reservoir (1). A striking member (29) is mounted so that a conical point is adjacent the plate (3). Lead styphnate (34) and nichrome wire are positioned adjacent the striking member (29). A squib (43) and combustion material (42) are provided to supplement the volume and pressure of the fluid. The squib (43) and the wire are in parallel. If a collision occurs, a signal is sent to the wire to ignite the lead styphnate (34) and drive the conical point of the striking member into the plate (3) to shatter it releasing fluid from the reservoir (1) into the cushion (2). At the same time, the signal ignites the squib (43), which ignites the combustion material (42) which in turn generates products to supplement the volume and pressure of the fluid.</p> |
