| 20080296919 | B-SHAPED BEAM WITH RADIUSED FACE BUT RECESSED CENTER - A B-shaped tubular reinforcement beam for vehicle bumper systems has a constant B section and longitudinal sweep. The tubular beam has a vertical cross section defining at least first and second tubes connected by a center web, and a front wall that extends across the tubes and the center web to define a channel. The channel has a depth dimension (D | 12-04-2008 |
| 20090195002 | Injection-Molded Plastic Nestable Shell for Concrete Parking Bumpers - A parking bumper shell that can be easily filled with a heavy form-filling material (such as concrete) to form a parking bumper is provided. The parking bumper shell may be injection molded from durable, brightly-colored, UV- and weather-resistant plastic. Undercuts, such as in the form of a plurality of undercut wings or z-puller pins, may be disposed on the interior of the parking bumper shell's top and side walls to aid in holding the parking bumper shell and the heavy filling material together. The parking bumper shell may also include internally projecting hollow extensions that are adapted to receive anchoring posts. While the parking bumper shell is being filled, it may be placed in a rigid frame which helps the shell to keep its shape during filling. The parking bumper shells are light-weight, nestable, and do not require internal steel rebar reinforcement, thereby greatly reducing transportation costs. | 08-06-2009 |
| 20140070554 | MOTOR VEHICLE BUMPER WITH AN INTEGRATED PEDESTRIAN PROTECTION SYSTEM - A motor vehicle bumper with a crossmember ( | 03-13-2014 |
| 20140346789 | VEHICLE IMPACT-ABSORBING MEMBER - A vehicle impact-absorbing member has a columnar wood member and a hollow cylindrical metal frame body covering side-surfaces of the wood member and is configured to axially receive a compression load caused by impact in the event of a collision in an axial direction of wood member. The frame body may have a square cylindrical shape. A ratio of an outer side in a hollow square cross-sectional surface of the frame body to a thickness of the frame body is set to a range of 9-12. | 11-27-2014 |
| 20150015007 | TUBULAR BEAM WITH CENTER LEG AND METHOD FOR FORMING THE SAME - A reinforcement beam is roll formed from a metal sheet for use in a vehicle bumper system. The reinforcement beam includes adjacent tubes having a common center wall and lateral portions extending from opposing sides of the common center wall that are roll formed simultaneously in the same rotational direction to enclose interior volumes of the adjacent tubes and to define top and bottom walls and front and rear wall of the reinforcement beam. The front walls of the adjacent tubes each include a channel rib depressed into the interior volume of the respective adjacent tube longitudinally along the reinforcement beam for stiffening the respective front wall. A weld is formed separately in each of the seams between the front walls and between the rear walls, thereby defining a crevice rib between the channel ribs to improve the bending strength and torsional strength of the reinforcement beam. | 01-15-2015 |
| 20150069773 | IMPACT ABSORBER - An impact absorber includes a an energy absorbing member that is formed of a composite material and absorbs impact energy by being crushed in a predetermined crush direction, an outer tube member disposed so as to surround the periphery of the energy absorbing member over the energy absorbing member along the crush direction, and a pressing member disposed so as to be in contact with the front end of the energy absorbing member and the front end of the outer tube member and presses the energy absorbing member and the outer tube member simultaneously in the crush direction to thereby crush them. The outer tube member is formed in a shape in which tubular portions are coupled in the crush direction, and is crushed in the crush direction while the tubular portions are regularly folded when the outer tube member is pressed by the pressing member in the crush direction. | 03-12-2015 |
| 20150291114 | Vehicle Bumper Beam, Associated Bumper Beam Assembly and Vehicle - A vehicle bumper beam having a crosspiece and at least one shock absorber. The shock absorber supports the crosspiece when fastened on the absorber and it includes a plate designed to fasten the shock absorber on a structure of a vehicle. The shock absorber is made from a plastic material optionally reinforced with fibers. The bumper beam has at least one connecting member connecting the plate of the shock absorber to the crosspiece. The connecting member is able to hold the crosspiece at the plate after deformation of the absorber in case of impact. | 10-15-2015 |
| 20150307045 | MULTI-STRIP BEAM-FORMING APPARATUS, METHOD AND BEAM - A multi-sheet beam includes sheets pre-shaped and/or pre-formed to have integral features and to cause a final beam shape with non-radiused corners and optimal impact properties when assembled, including beams with constant or varied cross sectional shapes. The non-radiused corners offer excellent impact strength over radiused corners. The sheets are selected to have desired (different) thicknesses and material properties for optimal impact results and low beam weight. To assemble, the sheets are fixtured together and welded to form box beam, such as a two-tube monoleg beam, preferably using welding processes having low heat-affected-zones around the weld. The multiple sheets can include grades of aluminum with high tensile strength well above extrudable grades of aluminum. Alternatively, the multiple sheets can be any grade of steel, such as high strength and ultra high strength steels. The fixturing and assembly technique minimizes capital expense on extruding machines and/or roll forming machines. | 10-29-2015 |
| 20150321631 | Energy Absorption Structure for a Motor Vehicle - An energy absorption structure for a vehicle has an energy absorption element, in particular an engine longitudinal carrier, and at least one impact transmission element, which impact transmission element is pressed against a side wall of the engine longitudinal carrier and, in the event of an impact, is guidable along the side wall, wherein the engine longitudinal carrier is a fiber composite component and the impact transmission element has a microstructure which can be countersunk into the engine longitudinal carrier. | 11-12-2015 |
