ABSTRACT:
A device for operating a side airbag is capable of rapidly deploying the side airbag and utilizing a physical collision force without an ECU. The device comprises a U-shaped beam deformed in the event of a crash to generate heat, a plurality of pairs of plate springs fixed along an inner base surface of the U-shaped beam at a predetermined interval, a thin metal plate fixed on the ends of each of the pairs of plate springs, a shape memory alloy member being capable of bending the pair of plate springs against resilient force thereof at a transformation temperature, and connecting the pair of plate springs, a contact electrically connected to the squib and being in contact with the thin metal plate by the deformation of the shape memory alloy member, and a temperature holding portion for constantly keeping the temperature of the U-shaped beam lower than the transformation temperature of the shape memory alloy member.
