Abstract
Abstract A safety belt for racing cars and rally sports cars which includes two shoulder belts and a lap belt which can be coupled to the shoulder belt by means of a buckle. The belts are at least indirectly fastened to the car frame. In the two shoulder belts of the safety belt, the kinetic energy resulting from an impact is converted to a different extent and the conversion of the kinetic energy takes place in the shoulder belts within time periods which are shifted relative to each other. As a result, the two shoulder belts are elongated asymmetrically and permit a rotation of the torso of the driver and a subsequent forward displacement of one shoulder relative to the other shoulder.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
In a safety belt to be worn by a driver of a car, the safety belt including two shoulder belts and a lap belt, and a buckle for coupling the lap belt to the shoulder belt, wherein the belts are at least indirectly fastened to the car frame, the improvement comprising the shoulder belts including means for converting the kinetic energy resulting from an impact of the car to a different extent and for converting the kinetic energy in the two shoulder belts in time periods which are shifted relative to each other, so that the two shoulder belts are elongated asymmetrically and permit a rotation of the torso of the driver and a subsequent forward displacement of one shoulder of the driver relative to the other shoulder.
Claim 2
Dependent Claim
128 words
In a safety belt to be worn by a driver of a car, the safety belt including two shoulder belts and a lap belt, and a buckle for coupling the lap belt to the shoulder belt, wherein the belts are at least indirectly fastened to the car frame, the improvement comprising the shoulder belts including means for converting the kinetic energy resulting from an impact of the car to a different extent and for converting the kinetic energy in the two shoulder belts in time periods which are shifted relative to each other, so that the two shoulder belts are elongated asymmetrically and permit a rotation of the torso of the driver and a subsequent forward displacement of one shoulder of the driver relative to the other shoulder.
Claim 3
Dependent Claim
41 words
The safety belt according to claim 1, wherein at least one of the shoulder belts includes an energy converting means, the energy converting means being a loop in the shape of a double-S held together by means of a transverse seam.
Claim 4
Dependent Claim
46 words
The safety belt according to claim 1, wherein at least one of the shoulder belts includes an energy converting means, the energy converting means being one or more loops, each loop being held together by means of a transverse seam, the loops forming a bellow-type configuration.
Claim 5
Dependent Claim
99 words
The safety belt according to claim 1, wherein at least one of the shoulder belts includes an energy converting means, the energy converting means including an anchoring claw at least indirectly connected to the car frame, the anchoring claw defining an oblong hole, the shoulder belt with the energy converting means having an end portion, the end portion extending past the anchoring claw and being folded onto itself, the folded portion extending through the oblong hole, wherein the folded portions of the belt portion are held together by means of seams provided on both sides of the oblong hole.
Claim 6
Dependent Claim
94 words
The safety belt according to claim 1, wherein at least one of the shoulder belts includes an energy converting means, the energy converting means including an anchoring claw at least indirectly connected to the car frame, the anchoring claw defining two slots, the shoulder belt with the energy converting means having an end portion, the end portion being folded around a bolt extending transversely of the belt, wherein the end portion of the belt extends through the two slots, so that the belt is movable relative to the anchoring claw against a clamping resistance.
Claim 7
Dependent Claim
19 words
The safety belt according to claim 1, wherein one of the shoulder belts is a woven warp yarn band.
