Abstract
The belt retractor comprises an integrated belt pretensioner and an energy converter for limiting the belt force occurring after the tensioning of the belt. Once the belt has tensioned a torsion bar (14) arranged coaxially in the belt reel (12) is in the force flow path. The locking mechanism of the belt retractor comprises two locking pawls (22, 24) rotatably mounted on one face of the belt reel (12), said pawls being insertable into a locking toothing (30, 32) surrounding them on the frame (10). The first end of the torsion bar (14) is connected to the belt reel (12) in a non-rotational arrangement while its second end (14b) comprises a control disc (42) mounted for limited rotation, with the control disc acting on the locking pawls (22, 24) at least during the phase of energy conversion, thus preventing them from engaging into the locking toothing (30, 32). This second end (14b) of the torsion bar (14) is couplable to the frame (10) in a non-rotational load-bearing arrangement.
