Abstract

The invention refers to a load-bearing structural part ( 2 ) of a seat structure of a vehicle seat, which has a cavity ( 21 ), in which a belt retractor ( 40 ) is arranged.

First claim

The invention claimed is:

1. A load-bearing structural part of a seat structure of a vehicle seat, comprising, the structural part has a cavity in which a seatbelt retractor is arranged, the seatbelt retractor including a belt reel having a seatbelt wound thereon and at least one additional subcomponent, the at least one additional subcomponent comprising at least one of, a load limiting device, an irreversible belt tensioner, and a reversible belt tensioner, each of the at least one additional subcomponent and the belt reel aligned in a coaxial manner relative to an axis of rotation of the belt reel and enclosed with the belt reel within the cavity.

2. The load-bearing structural part according to claim 1 , further comprising, the cavity has an opening through which the seatbelt wound on the belt reel is led out.

3. The load-bearing structural part according to claim 1 further comprising, the structural part is formed from one metal sheet piece.

4. The load-bearing structural part according to claim 1 further comprising, the structural part is formed from a fiber-reinforced plastic part.

5. The load-bearing structural part according to claim 1 further comprising, the structural part has one or more stiffening webs at least in the region of the cavity.

6. The load-bearing structural part according to claim 2 further comprising, the opening is closed by an insert part to enclose the seatbelt retractor within the cavity.

7. The load-bearing structural part according to claim 1 further comprising, the load-bearing structural part forms a top of a seat backrest.

8. The load-bearing structural part according to claim 5 further comprising, the one or more stiffening webs are placed between the belt reel and the at least one additional subcomponent.

9. The load-bearing structural part according to claim 1 further comprising, the seatbelt retractor belt reel is rotatably mounted about a rotation axis of the belt reel, and the seatbelt retractor is arranged such that the axis of the belt reel is aligned parallel to the longitudinal direction of a profile rail.

10. A load-bearing structural part of a seat structure of a vehicle seat, comprising,
the structural part has a cavity in which a seatbelt retractor is arranged,
the load-bearing structural part comprises a cross-sectionally U-shaped, one-sided open profile rail with first and second opposite legs, extending from a base surface, and
the cavity is formed by a space between the opposite legs.

11. The load-bearing structural part according to claim 10 , further comprising, the first and the second legs of the profile rail have different heights from the base surface.

12. The load-bearing structural part according to claim 11 , further comprising, one of the first and the second legs with a relatively smaller height in the intended installation position of the structural part is facing a seat surface of the vehicle seat.

13. The load-bearing structural part according to 10 further comprising, the seatbelt retractor is mounted in a first web which is supported between the first and the second legs of the profile rail.

14. The load-bearing structural part according to claim 13 , further comprising, at least a second web is supported between the first and the second legs of the profile rail, which is spaced from the first web.

15. The load-bearing structural part according claim 10 further comprising, the seatbelt retractor has a belt reel rotatably mounted about the rotation axis of the belt reel, and the seatbelt retractor is arranged such that the rotation axis of the belt reel is aligned parallel to the longitudinal direction of the profile rail.
