专利摘要:
A seat belt tensioning device consists of a device which moves the belt lock in the direction of belt tensioning, locks at the end of the tensioning movement and is activated by a so-called vehicle-sensitive system when predetermined critical acceleration values are exceeded. In order to provide a simple and functionally reliable construction, the carrier piece (2) connecting the belt lock (4) to a part fixed to the vehicle is guided in a longitudinally displaceable manner in a housing (1) connected permanently to the vehicle and the housing (1) is provided with a device which permits a pull-in movement of the carrier piece (2) and locks its movement in the opposite direction. The belt lock (4) or the carrier piece (2) is connected to one end of a flexible pulling element (10) whose other end is connected to a pretensioned spring (6) which when released conveys a pull-in movement to the belt lock (4) by means of the pulling element (10). The vehicle-sensitive system controls a locking device, which holds the spring (6) in its pretensioned position, in such a way that when predetermined acceleration values are exceeded the said device is released. …<IMAGE>…
