Abstract

A support element for positioning a first element, in particular a cover, on a second element, in particular a housing, includes an annular disk-shaped base body that can be positioned on a support rod fastened on the second element, the base body having on a first end face a support surface for making supporting contact with the first element, where the support element has, on the first end face, a plastically deformable projection forming the support surface.

First claim

What is claimed is:

1. A support for supporting a first element on a second element, the support comprising:
an annular disk-shaped base body (a) that is structured for positioning on a support rod that can be fastened on the second element, and (b) a first end face of which includes a plastically deformable projection forming a support surface for making supporting contact with the first element, wherein the first element is a cover, and wherein the projection is plastically deformable only by a force that is greater than a supporting force generated by supporting the cover.

2. The support element of claim 1 , wherein the projection is annular and coaxial relative to the base body as a whole.

3. The support element of claim 1 , wherein the projection is trapezoidal in cross section.

4. The support element of claim 1 , wherein a second end face of the base body that faces away from the first end face includes a stop configured to form an axial abutment on a radial projection of the support rod.

5. The support element of claim 1 , wherein the second element is a housing.

6. A support assembly for an electrically operated brake booster, the support assembly comprising:
a housing;
a cover situated on the housing;
a support rod that is fastened onto the housing and that extends from the housing to a region at a bottom of the cover; and
a support supporting the cover and including an annular disk-shaped base body (a) that is positioned on the support rod, and (b) a first end face of which includes a plastically deformable projection forming a support surface making supporting contact with the bottom of the cover, wherein the projection is plastically deformable only by a force that is greater than a supporting force generated by supporting the cover.

7. The support assembly of claim 6 , wherein the support element is slid onto the support rod up to a radial projection of the support rod.

8. The support assembly of claim 7 , wherein the radial projection is annular and coaxial relative to the support rod.

9. The support element of claim 6 , wherein a second end face of the base body that faces away from the first end face includes a stop that abuts a radial projection of the support rod ( 8 ).

10. A method for providing a support for supporting a cover on a housing, the method comprising:
deforming a plastically deformable projection of a first end face of a base body of the support as a function of a dimension of a gap required between the cover and the housing when the cover is pressed towards the first end face, wherein the projection is plastically deformable only by a force that is greater than a supporting force generated by supporting the cover.
