Safety belt system
First Claim
1. A safety belt system for a vehicle, said system including a three-point safety belt, a self-locking belt winding mechanism which is mounted on a structural part of said vehicle, and a clamping mechanism for said belt, said clamping mechanism being disposed on or in said structural part, and having clamping jaws, at least one of which is movable;
- the improvement therewith wherein said clamping mechanism is movably guided relative to said structural part; and
including a control mechanism for effecting movement of said clamping mechanism, and which includes, as said control mechanism for effecting movement of said clamping mechanism, a piston unit which is acted upon by a pressure medium, said piston unit including a piston rod which has an upper and lower end, and is movable along said structural part of said vehicle, with said clamping mechanism being connected to said upper end of said piston rod;
said unit further including a guide tube, as well as a piston which is connected to said lower end of said piston rod and is accommodated in said guide tube; and
fitting means provided for mounting said guide tube to said structural part of said vehicle.

Abstract
A safety belt system, especially for vehicles. The system has a three-point safety belt, a self-locking belt winding mechanism which is mounted on a structural part of the vehicle, and a clamping mechanism for the belt. The clamping mechanism is disposed on the structural part of the vehicle, and has at least one movable clamping jaw. The problem with a basic safety belt system of this type is that in particular the slack in the belt at the body of the strapped-in person, together with the belt elongation which additionally results due to the stretching of the belt, lead, upon activation of the clamping effect, to a forward shifting of the body, thus endangering the person who is strapped in. This problem is inventively solved by movably guiding the clamping mechanism on the structural part of the vehicle, and by providing a drive or control mechanism for the movement of the clamping mechanism.
