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.

L'invention concerne un actionneur (10) pour appareil de sécurité (12) monté sur un véhicule (14) et se déplaçant entre une position rentrée le long du véhicule et une position sortie vers l'extérieur du véhicule. Un logement (16) est monté de manière fixe sur le véhicule et une console (18) pivote sur le logement pour permettre le mouvement autour d'un axe de pivotement prédéterminé entre les positions rentrée et sortie. L'actionneur (10) comprend également un mécanisme d'entraînement (20) servant à faire pivoter la console (18) autour de l'axe de pivotement entre la position rentrée et la position sortie. Un ressort de torsion (22) est monté sur l'axe de pivotement et raccorde par torsion la console (18) et le mécanisme d'entraînement (20) pour permettre leur mouvement relatif lorsqu'une force prédéterminée est appliquée sur la console.
