Abstract:
1. A spindle drive comprising: a spindle nut; a threaded spindle driven axially by rotation of the spindle nut and mounted fixedly in terms of rotation with reference to a reference body; a linear guide having a groove, the axis of the threaded spindle being arranged parallel to the longitudinal direction of the linear guide so that the threaded spindle may travel axially through the linear guide, and a guide element connected to the threaded spindle and travelling with the threaded spindle through the linear guide; the guide element having a non-elastic body and an elastic element formed integrally with the non-elastic body, the elastic element comprising a fork-shaped arrangement of extensions that comprise free ends that are flexible to vary an outer width of the free ends transversely to the longitudinal direction of the linear guide, wherein, in an operational state of the guide element, the elastic element of the guide element is spring-loaded and located within and slidably engaged with the groove of the linear guide, such that during a linear sliding of the guide element within the groove of the linear guide, the elastic element remains spring-loaded with the outer width of the free ends transverse to the longitudinal direction of the linear guide remaining within a maximum groove width in the region used for linear guidance of the elastic element of the guide element, and wherein in a non-loaded state of the elastic element in which the guide element is removed from the groove guide, the outer width of the free ends transverse to the longitudinal direction of the linear guide is greater than the maximum groove width in the region used for linear guidance of the elastic element of the guide element.
