Housing for receiving a winding spring, coil spring arrangement, a method for the manufacture of such a housing, a method for the production of such a coil spring arrangement and the motor vehicle with such a coil spring arrangement

摘要

The present invention relates to housing for receiving a winding spring (20), wherein the housing is a multicomponent - plastic housing, the at least a first housing part (10) with at least one functional surface (60), and wherein the first housing part (10) a more (40) and a the more (40) at least partially surrounding layer (50), which forms the functional surface (60), the more (40) by means of thermoplastic foam injection molding, in particular in the mucell^®-The method, is made from a first plastic component and the the more (40) at least partially surrounding layer (50), which forms the functional surface (60), from a second plastic component is produced, which will be explained later in an injection molding process to the more (40) has been applied.
