Abstract
A self-locking belt reel-in mechanism for safety belts, especially of motor vehicles, including a housing and a belt reeling-in shaft mounted therein so that it cannot be displaced axially, but can be displaced radially under the effect of locking forces. The shaft can be arrested at both ends in toothings secured to the housing. The mechanism is accommodated in relatively narrow structural parts of the vehicle, such as the B-columns; thus, overall size is no problem. Furthermore, the load is to act uniformly upon the shaft in the event of high-load (a crash). In contrast, for normal operation it is only necessary to arrest one end of the shaft. One of the arresting arrangements is in the form of a locking member disposed in a recessed portion in the associated end of the belt reeling-in shaft. The depth of the recessed portion is such that the locking member is flush relative to the plane of the associated opening of the housing. The locking member is pivotably mounted eccentrically relative to the axis of the belt reeling-in shaft and is provided with tooth-like latching projections. The other arresting arrangement has a peripheral toothing flush with the plane of the associated opening of the housing. The recessed portion can have a resilient abutment for the locking member. Furthermore, the mounting of the belt reeling-in shaft can be effected via resilient bearing cups.
