Publication number: 20120068429Abstract: 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.Type: ApplicationFiled: June 6, 2011Publication date: March 22, 2012Applicant: Benteler Automobiltechnik GmbHInventors: WULF HÄRTEL, Ullrich Hammelmaier, Peter Koczar

Patent number: 6533025Abstract: An instrument panel support, positioned between A columns of a motor vehicle, has a profiled support member with an integrated air guide system. The profiled support member has at least one air inlet and at least one air outlet connected to the air guide system. The air guide system forms at least a portion of a heat exchanger of an air conditioner of the motor vehicle. Preferably, at least one heat exchanger conduit is integrated into the air guide system.Type: GrantFiled: June 5, 2000Date of Patent: March 18, 2003Assignee: Benteler AGInventors: Jürgen Krogmeier, Andreas Hitz, Rafael Carcia, Wulf Härtel

Patent number: 6516913Abstract: An axle support for motor vehicles has a U-shaped hollow frame with a transverse tube, a first curved transition portion connected to a first end of the transverse tube, and a second curved transition portion connected to a second end of the transverse tube, a first longitudinal tube connected to the first transition portion, and a second longitudinal tube connected to the second transition portion, wherein the first and second longitudinal tubes extend perpendicularly to the transverse tube in the same direction away from the transverse tube. The first and second longitudinal portions each have a curved section with a depression. The curved sections have an interior filled with an inner foamed member of hardenable foam.Type: GrantFiled: November 28, 2000Date of Patent: February 11, 2003Assignee: Benteler AGInventors: Wulf Härtel, Markus Scherp

Patent number: 6474708Abstract: 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.Type: GrantFiled: March 17, 2000Date of Patent: November 5, 2002Assignee: Benteler AGInventors: Ludger Gehringhoff, Wulf Härtel, Knut Schöne, Ralf Schmidt, Dieter Braun
