Abstract
An actuating device (10) for operating a safety unit (12) mounts on a vehicle (14) and moves between a retracted position adjacent the vehicle and an extended position extending outwardly from the vehicle. A housing (16) is fixedly mounted on the vehicle and a bracket (18) is pivotably mounted on the housing for movement about a predetermined pivot axis between the retracted and the extended positions. The actuating device (10) also includes a drive mechanism (20) for pivoting the bracket (18) about the pivot axis between the retracted position and the extended position. A torsional spring (22) is mounted about the pivot axis and torsionally interconnects the bracket (18) and the drive mechanism (20) for allowing relative movement therebetween when a predetermined force is applied to the bracket.
