A safety arrangement for passengers of a moving vehicle includes an inflatable air cushion for maintaining passengers in their seat positions and a plurality of gas generators for inflating the cushion. The cushion is inflatable at different rates depending on vehicle deceleration by the employment of an electrical release circuit. The circuit includes a piezoelectric sensor for providing a signal representative of deceleration, a first threshold value switch, an integrator, a plurality of threshold value switches having different thresholds and a plurality of firing elements for the gas generators. |
