A belt retractor for a vehicle safety belt comprises a frame and a belt spool (1) which is rotatably mounted in the frame, and at least one locking toothing (2, 3) which is connected with the belt spool. A first locking catch (5) and a second locking catch (6) are provided, which are supported on the frame and can engage into the at least one locking toothing (2, 3). The first locking catch (5) is able to swing about a point of rotation which is arranged such that with the first locking catch (5) guided into the locking toothing (2, 3) a virtual line, which passes through a point of contact between the first locking catch (5) and the locking toothing (2, 3) and stands perpendicularly on a tooth face in the point of contact, runs between the point of rotation and a rotation axis of the belt spool (1). The second locking catch (6) is able to swing about a point of rotation which is arranged such that with the second locking catch (6) guided into the locking toothing (2, 3), a virtual line which passes through a point of contact between the second locking catch (6) and the locking toothing (2, 3) and stands perpendicularly on a tooth face in the point of contact, runs on the side of the point of rotation facing away from the rotation axis of the belt spool (1).
A belt retractor for a vehicle safety belt, said belt retractor comprising a frame and a belt spool (1) which is rotatably mounted in said frame, and at least one locking toothing (2, 3) which is connected with said belt spool, a first locking catch (5) and a second locking catch (6) being provided, which are supported on said frame and can engage into said at least one locking toothing (2, 3), said first locking catch (5) being able to swing about a point of rotation which is arranged such that with said first locking catch (5) guided into said locking toothing (2, 3) a virtual line, which passes through a point of contact between said first locking catch (5) and said locking toothing (2, 3) and stands perpendicularly on a tooth face in said point of contact, runs between said point of rotation and a rotation axis of said belt spool (1), and said second locking catch (6) being able to swing about a point of rotation which is arranged such that with said second locking catch (6) guided into said locking toothing (2, 3), a virtual line which passes through a point of contact between said second locking catch (6) and said locking toothing (2, 3) and stands perpendicularly on a tooth face in said point of contact, runs on the side of said point of rotation facing away from said rotation axis of said belt spool (1).
