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), a first pawl (26) arranged at a face side (24) of a seat belt spool (14), the first pawl (26) having a tooth (30) adapted to engage with a clutch-side toothing (22) on the driving gear (16) by pivoting the first pawl (26) around a pivot axis (28) on the seat belt spool (14). A second pawl (40) is arranged at a face side (42) of the driving gear (16), the second pawl (40) being adapted to interact with a control disk (32) mounted on the seat belt spool (14), the control disk (32) being rotatable 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 first pawl (26) and the control disk (32), the guiding geometries (34, 36) including an axially extending guiding pin (82) that is arranged in a groove (76), the groove (76) having a parking section (80) extending in circumferential direction (U), the guiding pin (82) lying in the parking section (80) when the first pawl (26) is in the disengaged position so that the first pawl (26) is hindered from pivoting away from its disengaged position.
