Abstract:
A self-locking belt roller comprising:a belt winding shaft rotatably mountable in a housing, the belt winding shaft having a front side and a rear side; a profiled head; a torsion rod having a first end connected to the belt winding shaft and a second end connected in non-rotating manner to the profiled head which is moveable into a locking position with the housing in which rotation of the belt winding shaft is blocked and the torsion rod becomes operational to resist further extraction of a belt from the belt roller, whereby a first force limiting operation of the belt roller is effected thereby; a resistance facilitating element is formed on an extension which is disposed in non-rotating manner on the profiled head; and a deformation element in the form of a bending element for increasing the resistance force of the belt roller to further extraction of the belt at the time during which the torsion rod resists further belt extraction, the deformation element having one end disposed on the front face of the belt winding shaft on the side thereof adjacent to the front face of the profiled head and the deformation element being engaged by the resistance facilitating element during further rotation of the belt roller in a manner such that the resistance of the belt roller to further extraction of the belt is increased.
