A clutch (10) for a seat-belt tensioner in a vehicle has a driving element (14) adapted for being rotated in a driving direction (D) and in a releasing direction (R) and a driven element (18) connectable with a seat-belt spool, the driving element (14) and the driven element (18) having a common rotation axis (A). Further, a pawl (22) is provided that is being pivotally held at a pivot pin arranged on the driving element and forming a pivot axis (24), the pawl (22) being adapted to assume a disengaged position in which the pawl (22) is not in engagement with the driven element and from which it can be pivoted radially inwards by turning the driving element (14) in driving direction (D), an engaged position in which the pawl (22) engages the driven element (18) and couples the driving element (14) with the driven element (18), and a decoupled position in which the pawl (22) is not in engagement with the driven element (18) and cannot be engaged with the driven element (18) by turning the driving element (14) in driving direction (D). The clutch (10) further has a clutch disk ring (32) having an outer essentially circular circumference and a first clutch disk arm (36) extending inwards into an opening (34) enclosed by the clutch disk ring (32), the first clutch disk arm (36) interacting with the pawl (22) to guide the pawl (22) into and out of the engaged position, and the clutch disk ring (32) having a second clutch disk arm (46) extending inwards into the opening (34) enclosed by the clutch disk ring (32), the second clutch disk arm (46) being flexible in radial direction (r) and being spaced from the first clutch disk arm (36) so that the pawl (22) comes into contact with both clutch disk arms (36, 46) when moving into the decoupled position.
