Abstract

A restraint belt for occupants of vehicles having an air bag module which is provided in the pelvic area. The restraint belt extends as a double belt in the lap of the occupant. The first section of the double belt rests directly on the body of the occupant. The second section rests at least partially on the side of the first section facing away from the body of the occupant. The belt reverses direction as it transitions from the first section into the second section. The airbag module is placed on the second section of the double belt. The configuration of the restraint belt provides for a restraint effect of any airbag at the same time that the tension of the belt is increased, and to attain an additional tensioning effect.

Claims

a lap belt having a first and a second section integrally connected at a belt-deflecting point, wherein the first section is configured to contact the occupant and the second section overlies the first section; and

an airbag module connected to the second section.

2. The restraint belt of claim 1, wherein the belt-deflecting point is located in the area of a belt buckle.

3. The restraint belt of claim 1, further comprising a shoulder section integrally connected to the first section of the lap belt.

4. The restraint belt of claim 1, wherein the airbag module includes a pocket for retaining an airbag.

a first section;

a second section integrally connected to the first section at a belt-deflecting point, wherein the first section is configured to contact the occupant and the second section overlies the first section; and

an airbag module connected to the second section.

11. The lap belt of claim 10, wherein the airbag module includes an airbag positioned so that when the airbag inflates the first section remains in contact with the occupant.

12. A three-point belt for an occupant positioned in a seat of a vehicle comprising:
