Abstract

An actuating device for a safety arrangement in a vehicle has a pneumatic muscle as a drive and a pyrotechnical gas generator for feeding the pneumatic muscle.

Claims

1. An assembly comprising a safety apparatus and an actuating device, said actuating device comprising a drive and a pyrotechnic gas generator for, when actuated, actuating said drive, said safety apparatus including a raisable engine hood which can be transferred from an initial position into a raised position by said actuating device, said drive comprising a radially expandable, tubular body, said tubular body longitudinally contracting upon radial expansion of said tubular body to raise said engine hood.
