Abstract

A bodywork part of a motor vehicle includes a main body of plastic material and at least one structural reinforcement fastened at least partially to a first part main body. The piece also includes at least one connecting member of the first part and of a second part of the main body including an end, a portion of which forms a lock loop around a clamping element so as to secure the connecting member, the structural reinforcement and the first part.

First claim

The invention claimed is:

1. A motor vehicle bodywork part comprising:
a main body of plastic material comprising at least a first part and a second part, the first part having at least one orifice,
at least a structural reinforcement fastened at least partially on the first part, the structural reinforcement having at least one orifice facing the orifice of the first part, so as to form a through-hole,
at least one connecting member of the first part and the second part comprising an end, the end comprising at least one portion penetrating at least once into the through-hole and forming a lock loop around a clamping element so as to secure the at least one connecting member, the structural reinforcement and the first part.

2. The motor vehicle bodywork part according to claim 1 , wherein the first part of at least one of the main body and the structural reinforcement comprise, at the periphery of respective orifices thereof, at least one edge having a relief capable of wedging the portion of the end forming the lock loop.

3. The motor vehicle bodywork part according to claim 1 , wherein a portion of the end inserted into the through-hole is fastened to a non-introduced portion of the end.

4. The motor vehicle bodywork part according to claim 1 , wherein the at least one connecting member is connected to an anchor point of the second part.

5. The motor vehicle bodywork part according to claim 1 , further comprising a second structural reinforcement fastened at least partially onto the first part of the main body, the second structural reinforcement having the at least one orifice facing an orifice of the first part of the main body, so as to form a second through-hole.

6. The motor vehicle bodywork part according to claim 5 , wherein the at least one connecting member comprises a second end, the second end comprising at least one portion penetrating at least once into the second through-hole and forming a second lock loop around a second clamping element so as to secure the connecting member, the second structural reinforcement and the first part.

7. The motor vehicle bodywork part according to claim 5 , further comprising a second connecting member of the first part and the second part comprising an end, the end comprising at least a portion penetrating at least once into the second through-hole and forming a second lock loop around a second clamping element so as to secure the second connecting member, the second structural reinforcement and the first part.

8. The motor vehicle bodywork part according to claim 7 , wherein the second connecting member is connected to an anchor point of the second part, the anchoring point being, for example, a lock block.

9. The motor vehicle bodywork part according to claim 1 , wherein the motor vehicle bodywork part is an opening part.

10. A method of manufacturing a bodywork part of a motor vehicle, the method comprising:
producing of at least one structural reinforcement comprising at least one orifice,
producing of a main body of plastic material, the main body being subdivided into at least a first part and a second part, the first part having at least one orifice intended to be positioned facing the orifice of the structural reinforcement,
fastening of the structural reinforcement at least partially on the first part of the main body so that the facing orifices form a through-hole,
introduction of at least a portion of an end of a connecting member of the first part and the second part into the through-hole forming a lock loop around a clamping element so as to secure the connecting member, the structural reinforcement and the first part.

11. The method according to claim 10 , wherein the steps of producing the main body and fastening of the structural reinforcement at least partially on the first part of the main body are carried out concomitantly by overmolding the structural reinforcement during molding of the main body.

12. The motor vehicle bodywork part according to claim 3 , wherein the portion of the end inserted into the through-hole is fastened by adhesive.

13. The motor vehicle bodywork part according to claim 4 , wherein the anchor point is a lock block.

14. The motor vehicle bodywork part according to claim 9 , wherein the opening part is selected from the group consisting of a hatchback and a side door.
