Abstract
A vehicle mechanism with a housing may have a spindle/nut assembly and a rotation lock, where in order to displace a spindle rod of the spindle/nut assembly in the longitudinal direction of the spindle rod, a rotational movement of a spindle nut of the spindle/nut assembly is blocked by the rotation lock. In order to support the spindle nut such that it cannot rotate, and/or to facilitate an assembly of the vehicle mechanism, and/or the rotation lock, the rotation lock may have at least one elastomer element for retaining the rotation lock on the housing.
Claims20
A vehicle mechanism, comprising:
- a housing;
- a spindle nut assembly, the spindle nut assembly having a spindle rod and a spindle nut, wherein rotation of the spindle nut relative to the spindle rod causes relative movement between the spindle nut and the spindle rod in a longitudinal direction of the spindle rod;
- and
- a rotation lock,
- wherein the rotation lock is configured to engage the spindle nut to prevent rotation of the spindle nut relative to the rotation lock, and
- wherein the rotation lock has at least one elastomer element for securing the rotation lock to the housing.

A method, comprising:
- assembling a vehicle mechanism, the vehicle mechanism, comprising:
- a housing;
- a spindle nut assembly, the spindle nut assembly having a spindle rod and a spindle nut, wherein rotation of the spindle nut relative to the spindle rod causes relative movement between the spindle nut and the spindle rod in a longitudinal direction of the spindle rod;
- and
- a rotation lock,
- wherein the rotation lock is configured to engage the spindle nut to prevent rotation of the spindle nut relative to the rotation lock,
- wherein the rotation lock has at least one elastomer element for securing the rotation lock to the housing, and
- wherein the rotation lock is inserted into an interior chamber of the housing of the housing until the at least one elastomer element snaps in place in a receiver in the housing.
