Abstract

The present disclosure provides a bumper stop for a vehicle structural member. The bumper stop includes a main body having a supporting surface, an assembling surface opposite to the supporting surface and a side surface between the supporting surface and the assembling surface; and a hollow conical portion partially surrounding the side surface of the main body and connected to the main body along a perimeter of the main body. The hollow conical portion is made from elastic material and configured to be flipped from a first position to a second position.

First claim

The invention claimed is:

1. A bumper stop for a vehicle structural member, comprising:
a main body having a supporting surface, an assembling surface opposite to the supporting surface and a side surface between the supporting surface and the assembling surface; and
a hollow conical portion connected to the main body and surrounding the side surface of the main body, wherein the hollow conical portion is capable of being flipped from a first position to a second position.

2. The bumper stop of claim 1 , wherein the hollow conical portion includes a first surface and a second surface opposite to the first surface, the first surface is closer to the side surface than the second surface at the first position, and the second surface is closer to the side surface than the first surface at the second position.

3. The bumper stop of claim 1 , wherein the first surface forms an inner surface of the hollow conical portion and define a first receiving space at the first position, and the second surface forms an inner surface of the hollow conical portion and defines a second receiving space at the second position.

4. The bumper stop of claim 3 , wherein a portion of the main body adjacent to the assembling surface is received in the second receiving space at the second position.

5. The bumper stop of claim 1 , further comprising a fixing portion extending from the assembling surface of the main body to be mounted to the vehicle structural member.

6. The bumper stop of claim 5 , wherein a thread area is formed on a side surface of the fixing portion.

7. The bumper stop of claim 1 , wherein the main body and the hollow conical portion are made from rubber material and are integrally formed.

8. The bumper stop of claim 1 , wherein a thickness of the hollow conical portion decreases gradually in a direction away from the main body.

9. A bumper stop of a vehicle structural member, comprising:
a main body having a supporting surface, an assembling surface opposite to the supporting surface and a side surface between the supporting surface and the assembling surface; and
a hollow conical portion, wherein the hollow conical portion partially surrounds the side surface of the main body and is connected to the main body around a perimeter of the side surface of the main body and is capable of being flipped from a first position to a second position, wherein the hollow conical portion opens toward the supporting surface at the first position and opens toward the assembling surface at the second position, and the hollow conical portion is made from elastic materials.

10. The bumper stop of claim 9 , wherein the hollow conical portion covers a portion of the main body adjacent to the assembling surface at the second position.

11. The bumper stop of the claim 9 , wherein the hollow conical portion is deformable under an external force and is restored when the external force is removed.

12. A restraint assembly of a vehicle, comprising:
a vehicle structural member having a surface;
a bumper stop assembled to the vehicle structural member, including:
a main body having a supporting surface, an assembling surface opposite to the supporting surface and assembled to the surface of the vehicle structural member, and a side surface between the supporting surface and the assembling surface, and
a hollow conical portion connected to the side surface of the main body along a perimeter of the main body and configured to be flipped from a pre-assembly position to an assembled position; and
a trim member assembled to the surface of the vehicle structural member and including a through-hole through which the bumper stop passes;

wherein a projection area of the hollow conical portion on the trim member is larger than an area of the through hole.

13. The restraint assembly of claim 12 , wherein a free end of the hollow conical portion substantially contacts the trim member at an assembled position.

14. The restraint assembly of claim 12 , wherein the hollow conical portion is made of elastic material.

15. The restraint assembly of claim 14 , wherein the hollow conical portion opens toward a direction away from the assembling surface at the pre-assembled position and opens toward the assembling surface at the assembled position.

16. The restraint assembly of claim 15 , wherein a cross-sectional area of an open end of the conical portion is larger than an area of the through-hole of the trim member, and a place with which the hollow conical portion connecting the side surface is closer to the supporting surface.

17. The restraint assembly of claim 15 , wherein a cross-sectional area of an open end of the conical portion is smaller than an area of the through-hole of the trim member, and a place with which the conical portion connecting the side surface is closer to the assembling surface.

18. The restraint assembly of claim 12 , wherein the main body of the bumper stop is of cylindrical shape, and the hollow conical portion is a hollow frustum of cone.

19. The restraint assembly of claim 12 , wherein the vehicle structural member further includes an assembling hole to receive the bumper stop, wherein the bumper stop further includes a fixing portion extending from the assembling surface of the main body to be received in the assembling hole.

20. The restraint assembly of claim 12 , wherein the vehicle structural member is a trunk lid.
