ABSTRACT:
A blocking mechanism for a seat belt retractor has a belt reel (10) rotatably mounted in a frame (12), a ratchet toothing (16) arranged on the frame, a ratchet pawl (24) arranged on the belt reel (10) for cooperation with the ratchet toothing (16) and an inertial disc (20) used as a belt webbing-sensitive sensor element. The inertial disc (20) is rotatable relative to the belt reel (10). The ratchet pawl (24) is pivotally mounted on the inertial disc (20). The belt reel (10) has an actuating element (26a) engaging the ratchet pawl (24). In operation, the actuating element (26a) causes the ratchet pawl (24) to engage with the ratchet toothing (16) when the belt reel (10) is rotated relative to the inertial disc (20).
