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.
