Abstract
Abstract A plastic body for use in vehicle seats, having at least one element joined therewith to form a single structural unit, which element is made from a material having different physical characteristics than those of the plastic. The element is formed as a dampening element made from a plastically deformable metal securely connected with the plastic body and/or as an insert in the plastic body. Between the dampening element and/or insert and the plastic body an intermediate layer is provided, the intermediate layer being made from a material that permits relative movements between the plastic body and the dampening element and/or insert.
