| 20110198873 | ENERGY ABSORBER FOR A BUMPER ASSEMBLY OF A VEHICLE AND METHOD FOR THE MANUFACTURE THEREOF - An energy absorber for a bumper assembly of a vehicle and a method for the manufacture thereof are described. The absorber includes a tubular body ( | 08-18-2011 |
| 20110089707 | ENERGY ABSORBER FOR A VEHICLE BUMPER ASSEMBLY - The invention relates to an energy absorber for a vehicle bumper assembly, comprising a thrust transmitting section ( | 04-21-2011 |
| 20090174197 | METHOD FOR PRODUCING A SHOCK ABSORBER AND SHOCK ABSORBER THUS OBTAINED - The method includes providing a planar sheet part; forming the planar sheet part by drawing or conical spinning to the shape of a partially formed part made up of a plate and a provisional hollow portion extending from the plate with a revolution shape with respect to an axis perpendicular to the plate, and an end wall closing an end of the provisional hollow portion opposite to the plate; and elongating a section of the provisional hollow portion by cylindrical or conical spinning. The shock absorber is integral with a plate and an elongated hollow portion extending from the plate with a revolution shape. A section of the elongated hollow portion has a thickness that is thinner than the thickness of the plate. | 07-09-2009 |
| 20090058111 | REINFORCING BUMPER CROSS-MEMBER AND PRODUCTION METHOD THEREOF - The invention relates to a bumper cross-member including an elongated body having a three-dimensional configuration formed from several metal sheet elements joined together by welding and shaped. The three-dimensional configuration has a non-uniform open transversal section along the body. The method includes joining several metal sheet elements together by welding in order to produce a flat tailored blank and shaping the tailored blank to produce the body. Shaping is carried out by hot or cold stamping. The several metal sheet elements can be joined either mutually adjacent or overlaid by different welding techniques, they can be of different of identical thicknesses and of the same type or different types of steel. | 03-05-2009 |
