    摘要： A self-locking belt retractor for safety belts comprises a belt shaft and at least one belt-strap-sensitive control mechanism which has a control disk (10), coupled to the belt shaft, for controlling a locking element, and the locking element is coupled to the control disk (10) by means of pin (14) engaging in an oblong hole (13) in the control disk (10), said pin being guided in the oblong hole during the rotation of the control disk (10) relative to the belt shaft, the control disk (10) carrying an inertia element (15) the one blocking arm (17) of which, when triggered, pivots radially until it engages with a stationary toothed section owing to the rotational acceleration acting upon the control disk (10). A torsion spring (25) comprising two spring legs (27, 28) that are spaced apart from each other in the peripheral direction is mounted in a mounting point for the belt shaft and/or the control disk (10) such as to be rotatable between a position of rest against the inertia element (15) and a position of rest against a follower (21) that projects upwards from the plane of the control disk (10). The invention is characterized in that the two spring legs (27; 28, 50) of the torsion spring (25) arranged in a plane above the inertia element (15) and spaced apart from the plane of the control disk (10) enclose the follower (21) between them and stops (29, 53) of the torsion spring which extend into the plane of the control disk (10) extend over the follower, the follower (21) forming stop faces (22, 23) for the spring legs (27; 28, 50) for carrying the torsion spring (25) along when the control disk (10) is rotated in the belt retraction direction (arrow 40) or in belt withdrawal direction (arrow (41) such that the torsion spring (25) releases the inertia element (15) when the control disk (10) is rotated in the belt retraction direction (arrow 41) and prevents the inertia element (15) from pivoting when the control disk (10) is rotated in the belt retraction direction (arrow 40). The invention is further characterized in that the stop (29, 53) of the spring leg (28, 50) serving to carry the torsion spring (25) along in the belt retraction direction (arrow 40) extends into the trajectory of the pin (14) in the oblong whole (13) during the rotation of the control disk (10), thereby immobilizing the locking element on the belt shaft.
