Patent FR-2349024-A1 (FR)
IPC: E06B9/84
Filed: 1977-04-21
Abstract: The means for preventing rotation comprises a retaining element (18) which is connected to the winding drum (2, 10) and rotates with said winding drum (2, 10) when the latter is rotated intentionally and is locked when the winding drum (2, 10) is rotated unintentionally. In order to permit an uncomplicated and less heavy construction, the retaining element (18) is connected to the winding drum (2, 10) by means of an axial thread (22). For this purpose, there is further arranged an axially compliant deformation element (20) between at least one end surface (24) of the retaining element (18) and an opposite counter surface (26). When preventing rotation, the energy to be dissipated is thus converted at least partially into shape-changing energy.
