  • Publication number: 20120068429
    Abstract: In a method of making a stabilizer, a rubber molding is vulcanized onto an inner side of an outer shell to produce a rubber bearing. After coating a stabilizer bar, the rubber bearing is vulcanized onto the stabilizer bar in a joining zone while maintaining the rubber bearing under a defined tension using a biasing tool. After vulcanization and removal of the biasing tool, a bearing bracket is connected in surrounding relationship to the rubber bearing while maintaining the rubber bearing under a defined tension.

  • Patent number: 6474708
    Abstract: A bumper arrangement for a front end or a rear end of an automobile having a bumper cover enclosing the bumper arrangement has a transverse support having a first and a second end. First and second spacer consoles are connected to the first and second ends of the transverse support, respectively. First and second stop plates are connected to the first and second spacer consoles opposite the transverse support. The first and second stop plates secure the bumper arrangement to longitudinal support beams of the car body extending in the longitudinal direction of the automobile. A transverse beam is positioned below the transverse support in a mounted position of the bumper arrangement. Spacer stays connect the transverse beam to the stop plates and are positioned below the spacer consoles. The transverse support and/or the spacer consoles, at least over portions thereof, have two or more deformation areas arranged next to one another in the longitudinal direction of the automobile.
