The invention concerns a retractor restraint system (1, 1'), inparticular for securing wheelchairs and/or people in vehicles, including: ahousing (3), a retractor reel (5) mounted to the housing (3) rotatably in apositive and a negative direction of rotation for receiving a belt (7) whichcan be coupled to a wheelchair, wherein the belt (7) can be wound on by arotation of the reel (5) in the positive direction of rotation and can beunwound by a rotation of the reel (5) in the negative direction of rotation,an arresting unit (9) for arresting the reel (5) to prevent rotation in thenegative direction of rotation in an operating state of the retractorrestraintsystem (1, 1'), a clamping unit (11) arranged at the housing (3) forreleasably clamping fast the belt (7) unwound from the reel (5), and atriggering mechanism (13) for actuation of the clamping unit (11). Theinvention attains the stated object in that the triggering mechanism (13)can be coupled to the arresting unit (9) and the reel (5) in such a way thatthe clamping unit (11) is actuated when a torque acts on the reel (5) in thenegative direction of rotation and the reel (5) is arrested by the arrestingunit (9). The invention further solves the stated object by a method ofsecuring wheelchairs in vehicles by means of such a retractor restraintsystem and by the use of same.
