  • Patent number: 8061009
    Abstract: In the case of the method of the invention, the cables of a cable harness are preassembled on a metallic rivet bushing by the cable harness manufacturer in that the cable shoes of the cables are pushed onto the rivet bushing and are prevented from loosening by a subsequently formed upset ridge. The rivet bushing with the attached cables is then delivered to the vehicle manufacturer, who pushes the rivet bushing onto a stud bolt provided on the body part. The rivet bushing with the cables held by it is then immobilized on the stud bolt by a nut. An apparatus for performing the procedure as well as a rivet bushing therefore are also described.

  • Patent number: 7699555
    Abstract: A mounting assembly for releasably mounting a rear light member to a body member of a vehicle. The mounting assembly comprises a locking member. The locking member includes a sleeve-like mounting portion adapted to be fixed to the support member, and a first locking portion integrally joined to the mounting portion. The first locking portion is adapted to snappingly engage a matingly shaped second locking portion of the structural member for retaining it. The mounting assembly further comprises a release pin axially slidably in the mounting portion of the locking member. The release pin has a shaft portion axially project from the sleeve-shaped mounting portion and is adapted to be axially displaced for releasing the two locking portions from being snappingly engaged.

  • Publication number: 20090097913
    Abstract: A riveted joint between two sheet-metal components spaced at a certain distance by means of a spacing rivet is described. The spacing rivet is immobilized on the one sheet-metal component by a flange and a first upset ridge and on the other sheet-metal component by a shoulder and a second upset ridge. A spacing section of the spacing rivet extends between the first upset ridge and the shoulder in order to keep the two sheet-metal components at a certain distance from each other. A spacing rivet and a method for producing this type of riveted joint are also described.
