Abstract

An alignment system for aligning components includes a first component, a second component, upstanding, elongated tabs connected to at least one of the components, each elongated tab having a tab wall, and deformable elongated tab apertures formed in at least one of the components, each deformable tab aperture comprising opposing deformable aperture walls. The apertures are geometrically distributed in coordinated relationship to a geometrical distribution of the elongated tabs such that each elongated tab is receivable into a respective aperture and each tab has a width larger than a cross-sectional width of its respective aperture measured in a same direction. Each aperture is configured to elastically deform upon disposition of each elongated tab into its respective tab aperture at an interface between the tab wall and the aperture wall.

First claim

What is claimed is:

1. An alignment system for aligning components to each other, comprising:
a first component;
a second component;
a plurality of upstanding, elongated tabs connected to at least one of the first and second components, each elongated tab having a tab wall;
a plurality of deformable elongated tab apertures formed in at least one of the first and second components, each deformable tab aperture comprising opposing deformable aperture walls;
wherein the plurality of apertures are geometrically distributed in coordinated relationship to a geometrical distribution of the plurality of elongated tabs such that each elongated tab is receivable into a respective aperture and each tab has a width larger than a cross-sectional width of its respective aperture measured in a same direction;
wherein each aperture is configured to elastically deform upon disposition of each tab into each respective aperture at an interface between the tab wall of each tab and the aperture wall of each respective aperture;
an assembly of the first component and the second component, wherein each elongated tab is disposed in the corresponding elongated tab aperture and deforming the deformable aperture walls thereof, wherein each elongated tab has a top end that projects above a top edge of the respective aperture; and
a third component that is attached to the assembly having a surface disposed proximate the top ends of the elongated tabs, the surface having a plurality of recessed pockets disposed therein that are configured to receive the top ends of the elongated tabs.

2. The alignment system of claim 1 , wherein each of the deformable aperture walls comprises a deformable fixed beam.

3. The alignment system of claim 2 , wherein the deformable fixed beam is defined by an elongated beam aperture formed proximate the deformable aperture wall.

4. The alignment system of claim 3 , wherein the elongated beam aperture has a length that is greater than a length of the tab aperture.

5. The alignment system of claim 4 , wherein the elongated beam aperture extends beyond a first end and a second end of the tab aperture.

6. The alignment system of claim 2 , wherein the deformable fixed beam has a predetermined beam width.

7. The alignment system of claim 6 , wherein the predetermined beam width is selected to obtain a predetermined compliance characteristic of the deformable fixed beam.

8. The alignment system of claim 2 , wherein the deformable fixed beam is defined by a free surface of the respective component on which it is formed.

9. The alignment system of claim 8 , wherein the deformable fixed beam has a predetermined beam width.

10. The alignment system of claim 9 , wherein the predetermined beam width is selected to obtain a predetermined compliance characteristic of the deformable fixed beam.

11. The alignment system of claim 1 , wherein the plurality of elongated tabs each have a tab wall axis and a first portion of the plurality of elongated tabs have tab wall axes that are not-parallel to the tab wall axes of a second portion of the plurality of elongated tabs.

12. The alignment system of claim 11 , wherein the first portion of the elongated tabs have tab wall axes that are substantially orthogonal to the tab wall axes of the second portion of elongated tabs.

13. The alignment system of claim 1 , wherein the plurality of elongated tabs each have a beveled tab edge proximate a top end of the tab.

14. The alignment system of claim 1 , wherein the plurality of elongated tab apertures have a beveled aperture edge proximate an entrance opening of the tab aperture.

15. The alignment system of claim 1 wherein the assembly comprises a motor vehicle assembly.

16. The alignment system of claim 15 , wherein the motor vehicle assembly comprises a door assembly.
