Abstract
The seat belt retractor has a belt reel (12) rotatably mounted in a frame (10). A vehicle-sensitive latching mechanism includes a control disk (64) connected to the belt reel (12), rotation of which is lockable by means of the vehicle-sensitive inertial sensor (71, 71a, 73a, 75a). A belt tensioning drive engages the first axial end of a torsion bar (30), the second end of which is drivingly coupled to the belt reel (12). After belt tensioning the first end of said torsion bar (30) is blocked on the frame (10). Under the load subsequently introduced via the belt webbing (14) the torsion bar (30) is twisted about its axis for conversion of energy. The control disk (64) is connected to the belt reel (12) via a torque-limiting coupling (60, 62, 68, 74, 78; 92 to 106).
