A clutch (10) for a seat-belt tensioner in a vehicle has a driving gear (16) adapted for being rotated in a driving direction (D) and in a releasing direction (R) and a first pawl (26) arranged at a face side (24) of a seat belt spool (14), the first pawl (26) being able to engage a clutch-side toothing (22) on the driving gear (16) by pivoting around a pivot axis (28). A second pawl (40) arranged at a face side (42) of the driving gear (16) is provided that is adapted to interact with a control disk (32) mounted on the seat belt spool (14), the control disk (32) being rotatable about a predetermined rotation angle (α) with respect to the seat belt spool (14). The control disk (32) interacts with the first pawl (26) by way of guiding geometries (34, 36) on the control disk (32) and the first pawl (26). A relative angular position of the teeth of a control disk toothing (46) and of the teeth of the clutch-side toothing (22) on the driving gear (16) during the engagement of the first pawl (26) are determined so that the tooth (30) of the first pawl (26) is pivoted into the clutch-side toothing (22) between two adjacent teeth of the clutch-side toothing (22).
