Adapter, module with adapter and method for mounting such a module

The adapter (10) comprises a mounting element (12), on which a component-side holding portion is mounted, and another mounting element (14), on which a vehicle-side holding element is mounted. The two mounting elements are movably coupled with each other by a spring element. The two mounting elements are formed substantially in a cylindrical shape, where the latter mounting element surrounds in the circumferential direction. The cylindrical longitudinal axes (L) of the two mounting elements are concentric. Independent claims are included for the following: (1) an assembly for vehicle-side mounting of a component, particularly a trim part; and (2) a method for mounting an assembly.
