Abstract
A self-locking belt roller has a housing and a belt winding shaft rotatably mounted in housing. A torsion rod has a first end connected in the belt winding shaft. A profile head is connected to a second end of the torsion rod. A blocking member, that is vehicle-sensitive and/or belt-sensitive, is mounted on the profile head and moveable into a locking position at the housing in which rotation of the belt winding shaft is blocked. An energy-dissipating structure is positioned within a force transmission path, including the profile head, the torsion rod, and the belt winding shaft, for increasing a restraining force before the torsion rod becomes effective or simultaneously to the torsion rod becoming effective and for obtaining a degressive force characteristic curve.
