Abstract

A cap for mounting on a damper tube of a vibration damper, having an outer shell region that is cylindrical at least in sections and at least one elastic spring tongue. At least one positively locking element is arranged on the spring tongue in order to produce a positively locking connection between the cap and a protective element of the vibration damper. The at least one spring tongue has a region which, in the non-mounted state of the cap, is set back inwardly in the radial direction with respect to the outer shell region. The set-back region has a spreading element, by way of which the spring tongue is spread outwardly in the radial direction during the mounting of the cap.

First claim

The invention claimed is:

1. A cap for assembly onto a damper tube of a vibration damper, the cap comprising:
an outer peripheral region that is cylindrical at least in sections;
at least one resilient spring tongue, wherein disposed on the at least one spring tongue is at least one positive-locking element configured to produce a positive-locking connection between the cap and a protective element of the vibration damper; and
a circular ring shaped stop surface of the outer peripheral region, which is configured to position the protective element, by means of which the protective element is positionable relative to the positive-locking element in a position suitable for forming the positive-locking connection,
wherein the at least one spring tongue comprises a region that is set back radially inwards with respect to the outer peripheral region in a non-assembled state of the cap,
wherein the set-back region comprises a spreading element configured so that the at least one spring tongue is radially spread outwards when the cap is being assembled, and
wherein the protective element has a bellows-shaped interior profile having a plurality of recesses and the at least one spring tongue is configured to engage into one of the plurality of recesses in an assembled state such that the cap is retained against an upward and downward movement in an axial direction of the cap.

2. The cap as claimed in claim 1 , wherein the at least one spring tongue comprises several spring tongues disposed so that they are distributed over a periphery of the cap.

3. The cap as claimed in claim 1 , wherein the spreading element is an inclined surface or rounded section configured to cooperate with the damper tube when the cap is being assembled.

4. The cap as claimed in claim 1 , wherein the at least one positive-locking element is an integral component of the at least one spring tongue.

5. A cap for assembly onto a damper tube of a vibration damper, the cap comprising:
an outer peripheral region that is cylindrical at least in sections;
at least one resilient spring tongue, wherein disposed on the at least one spring tongue is at least one positive-locking element configured to produce a positive-locking connection between the cap and a protective element of the vibration damper; and
a circular ring shaped stop surface of the outer peripheral region, which is configured to position the protective element, by means of which the protective element is positionable relative to the positive-locking element in a position suitable for forming the positive-locking connection,
wherein the at least one spring tongue comprises a region that is set back radially inwards with respect to the outer peripheral region in a non-assembled state of the cap,
wherein the set-back region comprises a spreading element configured so that the at least one spring tongue is radially spread outwards when the cap is being assembled, and
wherein, in a direction of insertion of the cap into the protective element, an entirety of the at least one spring tongue, including the at least one positive-locking element, is arranged closer to a top of the cap than the stop surface.

6. The cap as claimed in claim 5 , wherein the at least one spring tongue comprises several spring tongues disposed so that they are distributed over a periphery of the cap.

7. The cap as claimed in claim 5 , wherein the spreading element is an inclined surface or rounded section configured to cooperate with the damper tube when the cap is being assembled.

8. The cap as claimed in claim 5 , wherein the at least one positive-locking element is an integral component of the at least one spring tongue.
