Patent number: 8152210Abstract: A bumper for a motor vehicle includes a lightweight cross member attachable transversely to the longitudinal rails of the motor vehicle frame. The cross member includes two longitudinal profiles which are displaceable relative to each other and support each other during the displacement. The bumper provides improved functionality and increased energy absorption capability.Type: GrantFiled: November 30, 2009Date of Patent: April 10, 2012Assignee: Benteler Automobiltechnik GmbHInventors: Ulrich Lütke-Bexten, Michael Roll, Elmar Mollemeier

Publication number: 20110006559Abstract: In a method of making a body for a motor vehicle, shaped components are produced from blanks using at least one forming process. The shaped components are provided with rivet holes, and a coating is applied onto the shaped components for corrosion protection. After applying the corrosion protection, the shaped components are joined with the body via rivets.Type: ApplicationFiled: July 2, 2010Publication date: January 13, 2011Applicant: Benteler Automobiltechnik GmbHInventors: JOHANNES SCHÄFERS, Ulrich Lütke-Bexten, Markus Kettler

Publication number: 20100203272Abstract: A method for producing a motor vehicle component and a motor vehicle component produced by this method are disclosed. A tubular body made of metal, in particular high-strength steel, is filled with a granular material and subsequently heated. During the heat treatment, the granular material melts and then hardens during cool-down to form an interior reinforcement.Type: ApplicationFiled: February 3, 2010Publication date: August 12, 2010Applicant: Benteler Automobiltechnik GmbHInventors: JOHANNES SCHÄFERS, ULRICH LÜTKE-BEXTEN, MARKUS KETTLER

Publication number: 20100133859Abstract: A bumper for a motor vehicle includes a cross member extending transversely to side rails of a vehicle frame. The cross member has a U-shaped cross section which is defined by a web connected on opposite ends to two legs, respectively, and configured to point in a direction of the motor vehicle. The web has a reinforcement embossment in a central length section of the cross member.Type: ApplicationFiled: November 30, 2009Publication date: June 3, 2010Applicant: Benteler Automobiltechnik GmbHInventors: Ulrich Lütke-Bexten, Michael Roll, Elmar Mollemeier

Patent number: 7399013Abstract: A bumper for a motor vehicle includes a cross member which is disposed transversely to side rails of a motor vehicle frame and connected to the side rails via crash boxes. The cross member has a C-shaped cross section and includes an outer shell member and an inner shell member. The inner shell member is constructed as tension link which is made of a material having a tensile strength that is greater than the tensile strength of a material of the outer shell member.Type: GrantFiled: August 9, 2006Date of Patent: July 15, 2008Assignee: Benteler Automobiltechnik GmbHInventors: Ulrich Lütke-Bexten, Michael Roll, Elmar Mollemeier

Patent number: 7360811Abstract: A bumper for a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame, and a crash box which is connected between the side rails and the cross member. The crash box is configured in fold construction from a metal sheet and has a sidewall which exhibits a roof-shaped structure. The sidewall includes at least one wall section which is inclined in relation to the horizontal midsection transverse plane of the crash box.Type: GrantFiled: June 22, 2006Date of Patent: April 22, 2008Assignee: Benteler Automobiltechnik GmbHInventors: Michael Roll, Ulrich Lütke-Bexten

Patent number: 7357432Abstract: A bumper for a motor vehicle includes a cross member disposed transversely to side rails of a motor vehicle frame and having a U-shaped cross section with a wall and two legs extending from opposite ends of the wall. The cross member is supported via integral crash boxes against the side rails. Each crash box has a cross member proximal end which abuts against the wall of the cross member, and includes vertical legs and horizontal legs to define a casing-like configuration. The wall of the cross member is formed in an area of the cross member proximal end of the crash box with a depression which extends in a direction of the crash box, with the vertical legs of the crash box joined at the cross member proximal end to the wall of the cross member, and with the horizontal legs of the crash box spaced from the wall of the cross member by a distance.Type: GrantFiled: June 22, 2006Date of Patent: April 15, 2008Assignee: Benteler Automobiltechnik GmbHInventors: Michael Roll, Ulrich Lütke-Bexten, Wilhelm Arns, Elmar Mollemeier
