Abstract

The device comprises a drum around which a belt is wound under the action of a return spring. This spring acts through a cable passing around two pulleys of variable diameter which produce a return force which is independent of the extent of the winding of the belt. Moreover, the cable passes around a pulley which permits transmitting to a device responsive to acceleration a value which represents the linear acceleration of the belt which is also independent of the extent of the winding of the belt.
