Publication number: 20170292169Abstract: A metal piece for a motor vehicle has a generally elongated shape according to a longitudinal direction. The piece includes at least one edge extending according to the longitudinal direction, at the intersection of two walls of the piece, and at least one area having a mechanical strength lower than the rest of the body of the piece, wherein the at least one area is formed through local thermal control of the piece. The lower mechanical strength area of the piece undulates along the edge, extending alternatingly along each of the walls forming the edge. A method for making the metal piece is also disclosed.Type: ApplicationFiled: September 22, 2015Publication date: October 12, 2017Inventors: Christophe CAZES, Grégory GATARD, Daniel BERGLUND, Martin HOLMBERG

Patent number: 8684449Abstract: The invention relates to a B-pillar for a vehicle including a main section (20) with a hat-shaped section (21) comprising a central flange (22), two web portions (23, 24) and two side flanges (25, 26). At least the hat-shaped section (21) is press-hardened and has a breaking strength in excess of 1400 MPa and the side flanges (25, 26) of the hat-shaped section (21) have a breaking strength below 1100 MPa along at least part of the length of the side flanges (25, 26). The B-pillar (13) includes a cover plate (40) welded to the side flanges (25, 26) of the hat-shaped section (21) so as to form a closed profile, the cover plate (40) having a breaking strength below 1100 MPa at least in the region in which it bears against the side flanges (25, 26). The side flanges (25, 26) of the hat-shaped section have a breaking strength below 1100 MPa in the region in which the side flanges bear against the cover plate (40).Type: GrantFiled: December 12, 2010Date of Patent: April 1, 2014Assignee: Gestamp Hardtech ABInventors: Hans Bodin, Jan Krispinsson, Paul Akerstrom, Daniel Berglund, Lars Wikstrom, Martin Holmberg

Patent number: 8465088Abstract: An A-pillar for a vehicle includes a first part (15) extending as far as the windscreen and supporting the door hinges and a second arcuate part (16) extending up along the windscreen and continuing towards the back in order to serve as a roof beam (19) above the door. This second part consists of two open sections (23, 24) with flanges (25, 26; 27, 28) welded together so as to give the pillar a closed profile. At least one of the sections (23) is press-hardened and has a breaking strength in excess of 1400 MPa and the flanges (25, 26; 27, 28) of the sections have a breaking strength below 1100 MPa in a portion (35) situated above the door.Type: GrantFiled: December 11, 2010Date of Patent: June 18, 2013Assignee: Gestamp Hardtech ABInventors: Hans Bodin, Jan Krispinsson, Paul Akerstrom, Daniel Berglund, Lars Wikstrom, Martin Holmberg

Publication number: 20090303730Abstract: An undercabinet light fixture, comprising a housing for supporting a light source. A glare-eliminating optical system is mounted on the housing and through which light illuminated by the light source passes. The glare-eliminating optical system includes a textured surface and a non-textured surface. The textured surface includes an array of longitudinally extending prismatic elements for redirecting light illuminated from the light source. The non-textured surface is located below the light source and permits light illuminated from the light source to pass therethrough without being substantially redirected.Type: ApplicationFiled: September 5, 2008Publication date: December 10, 2009Applicant: LUXO ASAInventor: Stein Martin Holmberg
