Abstract
This return tightener comprises a force accumulating device (1) which may be actuated in response to the detection of a sudden deceleration of the vehicle and is connected to a device (2) for driving a device (3) for rotationally actuating a shaft (4) of the winder, the driving device comprising a flexible driving element (9). This tightener is characterized in that the actuating device comprises a split elastically yieldable ring (5) disposed around a portion of the shaft and around which is wound a reserve portion of the flexible driving element (9), and an abutment element (6) is provided interposed between the two edges of the ring (5) to permit a free rotation of this portion of the shaft in this ring in normal operation of the winder. This abutment element (6) is connected to the flexible driving element (9) and is capable of being pulled away by the latter upon the actuation of the accumulating device (1) for releasing the edges of the ring (5) and permitting a coupling between the driving device (2) and the shaft (4) of the winder and cause the winding of the strap.
