Patent ID: 7963562

Claim:
A safety belt system for a motor vehicle, comprising: a safety belt extending in a direction of extension of the belt, a shoulder portion of the safety belt for bearing against an upper body of a person strapped-in according to requirements by means of the safety belt, a buckle element which subdivides the safety belt into the shoulder portion and a further belt portion, the buckle element deflecting the safety belt in the direction of extension of the belt such that the two portions extend away in different spatial directions from the buckle element, a mobile region of the buckle element, which under the action of forces caused by a crash is mobile from an initial position in which the safety belt may slide along the buckle element into a final position, in which the safety belt is fixed to the buckle element, the mobile region being designed and provided to fix the safety belt before reaching the final position on the buckle element, and the safety belt cooperating with the mobile region, such that the mobile region is movable by a force acting on the shoulder portion which tensions the shoulder portion in the direction of extension of the belt, from its initial position into its final position and in that by the movement of the mobile region into the final position the shoulder portion is relieved such that the resulting force acting on the shoulder portion is limited, wherein the fixing of the safety belt on the buckle element is carried out by the mobile region itself, and wherein the mobile region is connected to a part of the buckle element via at least one deformation element when the mobile region has moved out of its initial position.
