Patent number: 6280132Abstract: An arrangement for fastening of an assembly part on a carrier part includes at least one fastening screw, a sleeve, and a flexible assembly ring whose inner diameter is smaller than an outer diameter of a sleeve head flange and foot flange and which is arranged between the head flange and foot flange on the sleeve. The assembly part includes a through-bore in the assembly part whose inner diameter is at lest as large as the outer diameter of the foot flange, into which the sleeve is inserted. The lower side of the head flange is indirectly or directly supported on the upper edge region of the through-bore. The inner diameter of the through-bore is dimensioned such that the assembly ring is radially pressed together therein and by way of this clamped in and/or the through-bore comprises an undercut with an inner diameter so that the assembly ring under radial compression and subsequent expansion is pushed through the undercut and by which the assembly ring is retained in the through-bore.Type: GrantFiled: February 26, 1999Date of Patent: August 28, 2001Assignee: ITW Automotive Products GmbH & Co.Inventors: Adi Szczukowski, Klaus Spickenheier, Peter Kirchhoff
