Abstract

In one aspect, an elastically averaged alignment system is provided. The system includes a first component having a first alignment member and a second alignment member extending outwardly away from each other, and a second component having an inner wall defining an alignment aperture, the inner wall having a first wall and an opposite second wall. The first and second alignment members are an elastically deformable material such that when the first and second alignment members are inserted into the alignment aperture, the first and second alignment members elastically deform to an elastically averaged final configuration to facilitate aligning the first component with the second component in a desired orientation.

First claim

What is claimed is:

1. An elastically averaged alignment system comprising:
a first component comprising a plurality of alignment member groupings, each of the plurality of alignment member groupings including two first alignment members and a second alignment member extending outwardly away from each other; and
a second component comprising a plurality of alignment apertures, each of the plurality of apertures including an inner wall having a first wall and an opposite second wall,
wherein the first and second alignment members are an elastically deformable material such that when the first and second alignment members are inserted into one of the plurality of alignment apertures, the first and second alignment members elastically deform to be received by one of the plurality of alignment apertures and thereafter expand outwardly to retain the first component relative to the second component thereby establishing an elastically averaged final configuration to facilitate aligning the first component with the second component in a desired orientation.

2. The system of claim 1 , wherein the first component further comprises a central axis, and wherein the first alignment member is oriented at a first angle with respect to the central axis, the first alignment member elastically deforming against the first wall and the second alignment member elastically deforming against the second wall.

3. The system of claim 1 , wherein the inner wall further includes a third wall and an opposite fourth wall, wherein the first alignment member elastically deforms against the third wall and the second alignment member elastically deforms against the fourth wall.

4. The system of claim 2 , wherein the second alignment member is oriented at a second angle with respect to the central axis.

5. The system of claim 1 , wherein at least one of the first and second alignment members comprises an angled lead-in surface configured to facilitate insertion of that alignment member into the alignment aperture.

6. The system of claim 1 , wherein at least one of the first and second alignment members comprises a retention member extending therefrom.

7. The system of claim 6 , wherein the retention member includes an angularly extending insertion surface and a retention surface configured to engage a portion of the second component to facilitate insertion and subsequently prevent removal of its associated alignment member from the alignment aperture.

8. The system of claim 1 , wherein the second alignment member is positioned between the two first alignment members.

9. The system of claim 1 , wherein the plurality of alignment member groupings are geometrically distributed with respect to the plurality of alignment apertures, such that portions of the elastically deformable first and second alignment members of each of the plurality of alignment member groupings, when engaged with respective ones of the plurality of alignment apertures, elastically deform to an elastically averaged final configuration that further aligns the first component with the second component in four planar orthogonal directions.

10. A vehicle comprising:
a body; and
an elastically averaged alignment system integrally arranged within the body, the elastically averaged alignment system comprising:
a first component comprising a plurality of alignment member groupings, each of the plurality of alignment member groupings including two first alignment members and a second alignment member extending outwardly away from each other; and
a second component comprising a plurality of alignment apertures, each of the plurality of apertures including an inner wall having a first wall and an opposite second wall,
wherein the first and second alignment members are an elastically deformable material such that when the first and second alignment members are inserted into one of the plurality of alignment members, the first and second alignment members elastically deform to be received by one of the plurality of alignment apertures and thereafter expand outwardly to retain the first component relative to the second component thereby establishing an elastically averaged final configuration to facilitate aligning the first component with the second component in a desired orientation.

11. The vehicle of claim 10 , wherein the first component further comprises a central axis, and wherein the first alignment member is oriented at a first angle with respect to the central axis, the first alignment member elastically deforming against the first wall and the second alignment member elastically deforming against the second wall.

12. The vehicle of claim 11 , wherein the second alignment member is oriented at a second angle with respect to the central axis.

13. The vehicle of claim 10 , wherein at least one of the first and second alignment members comprises an angled lead-in surface configured to facilitate insertion of that alignment member into the alignment aperture.

14. The vehicle of claim 10 , wherein at least one of the first and second alignment members comprises a retention member extending therefrom, and wherein the retention member includes an angularly extending insertion surface and a retention surface configured to engage a portion of the second component to facilitate insertion and subsequently prevent removal of its associated alignment member from the alignment aperture.

15. The vehicle of claim 10 , wherein the second alignment member is positioned between the two first alignment members.

16. The vehicle of claim 10 , wherein the plurality of alignment member groupings are geometrically distributed with respect to the plurality of alignment apertures, such that portions of the elastically deformable first and second alignment members of each of the plurality of alignment member groupings, when engaged with respective ones of the plurality of alignment apertures, elastically deform to an elastically averaged final configuration that further aligns the first component with the second component in four planar orthogonal directions.

17. The vehicle of claim 10 , wherein the first component is a strip of trim and the second component is a vehicle door.

18. A method of manufacturing an elastically averaged alignment system, the method comprising:
forming a first component having a plurality of alignment member groupings each including a first alignment member and a second alignment member extending outwardly away from each other;
forming a second component having a plurality of alignment member apertures each including an inner wall having a first wall and an opposite second wall; and
forming the first and second alignment members from an elastically deformable material such that when the first and second alignment members are inserted into one of the plurality of alignment apertures, the first and second alignment members elastically deform to be received by one of the plurality of alignment apertures and thereafter expand outwardly to retain the first component relative to the second component thereby establishing an elastically averaged final configuration to facilitate aligning the first component and the second component in a desired orientation.
