| 20080224487 | CRASH BOX AND BUMPER FOR A MOTOR VEHICLE - A crash box for placement between a bumper beam and a side rail of a motor vehicle includes a longitudinal profile made of two U-shaped shells having overlapping ends sized to realize a material doubling for increasing side stiffness and to suit the side stiffness to a load level. A flange plate is provided on a side-rail-proximal end of the longitudinal profile and has an opening for passage of the longitudinal profile. The side-rail-proximal end of the longitudinal profile is configured with a collar which is turned outwards. The collar rests against the flange plate and is joined with the flange plate. In the event of a collision, the longitudinal profile of the crash box is moved into the side rail as the longitudinal profile folds into the side rail starting from the flange plate, while the side-rail-proximal end of the longitudinal profile remains secured to the flange plate. | 09-18-2008 |
| 20080228356 | SAFETY DEVICE FOR A MOTOR VEHICLE - A safety device for a motor vehicle includes a deformation element which is arranged between a bumper beam and a side rail and moves into the side rail in the event of an impact. The deformation element is configured in the form of an evertable tubular member having a side-rail-proximal rear end provided with an abutment ring. Operatively connected to the deformation element is an actuator which is provided to release a displacement of the deformation element into the side rail in a predefined speed range by liberating the abutment ring in relation to the side rail in a release position, and to block the displacement of the deformation element into the side rail, when the speed range is exceeded or a vehicle speed is below the speed range, by locking the abutment ring in relation to the side rail in an engagement position. | 09-18-2008 |
| 20090045638 | METHOD OF MAKING A BUMPER STRUCTURE OF A MOTOR VEHICLE, AND BUMPER STRUCTURE - In a method of making a bumper structure of a motor vehicle, a blank of quenched and tempered steel is formed into a U-shaped bumper beam having a middle part and attachment parts which adjoin the middle part on opposite ends and define crash boxes. The middle part of the bumper beam is hardened either during or after the blank is formed into the bumper beam. | 02-19-2009 |
| 20090162688 | METHOD OF MAKING A HYBRID STRUCTURE, AND HYBRID STRUCTURE - In a method of making a hybrid structure, at least one support body is fixed in a tube component which is then placed in an injection molding tool. An injection-molded part is injection-molded to an outer surface of the tube component in an area of the support body. As a result, the tube component is inwardly deformed, when regions adjacent to the support body are exposed to an injection pressure, and forms indentations for engagement of the injection-molded part. | 06-25-2009 |
| 20090236163 | MOTOR VEHICLE WITH COMPRESSED-GAS TANK - A motor vehicle includes a compressed-gas tank which is disposed in a wheel well of a spare wheel. The compressed-gas tank has a circular-cylindrical configuration defined by an axis of rotation and includes tie elements in parallel relationship to the axis of rotation. | 09-24-2009 |
| 20090243312 | CRASH BOX - A crash box for incorporation between a bumper beam and a side rail of a motor vehicle includes an outer tube which is made of a hardened steel material, and an inner tube which is held in the outer tube in a way that the inner and outer tubes are movable in relation to one another. When shifted by the outer tube, the inner tube deforms to thereby convert impact energy in deformation energy, thereby decreasing electric energy. | 10-01-2009 |
| 20090243313 | CRASH BOX - A crash box for installation between a bumper beam and a side rail of a motor vehicle includes an outer tube, and an inner tube which is held inside the outer tube, with the outer and inner tubes being movable in relation to one another. At least one of the inner and outer tubes is provided with a coat of varnish at least in a contact area between the outer pipe and the inner pipe. | 10-01-2009 |
| 20100101296 | METHOD OF REHEATING STEEL PART - A steel part with regions of different ductility is made by first loading the part onto a heatable rack and then heating the rack with the part on it in a furnace to a temperature above the AC | 04-29-2010 |
| 20100194125 | BUMPER FOR A MOTOR VEHICLE - A bumper for a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame. A crash box is incorporated between the cross member and the side rail, with set bolts being provided to join the crash box to the cross member in the absence of prepunching. | 08-05-2010 |
| 20100237639 | Bumper system - A bumper system for motor vehicles has a cross-member and two crush boxes. The cross-member is made from steel and the crush boxes are made from aluminum, or vice versa. The bumper member that is made from steel has a zinc coating on at least the joint area thereof. A braze weld fixedly connects the crush boxes to the cross-member along associated joints. | 09-23-2010 |
| 20100276950 | CRASH BOX AND BUMPER FOR A MOTOR VEHICLE - A crash box for placement between a bumper beam and a side rail of a motor vehicle includes a longitudinal profile made of two U-shaped shells having overlapping ends sized to realize a material doubling for increasing side stiffness and to suit the side stiffness to a load level. A flange plate is provided on a side-rail-proximal end of the longitudinal profile and has an opening for passage of the longitudinal profile. The side-rail-proximal end of the longitudinal profile is configured with a collar which is turned outwards. The collar rests against the flange plate and is joined with the flange plate. In the event of a collision, the longitudinal profile of the crash box is moved into the side rail as the longitudinal profile folds into the side rail starting from the flange plate, while the side-rail-proximal end of the longitudinal profile remains secured to the flange plate. | 11-04-2010 |
| 20110121587 | BUMPER SYSTEM - A bumper system includes a crossbeam having ends constructed to form attachment zones, and two crash boxes which are secured to side rails of a motor vehicle and coupled to the attachment zones, respectively. The crossbeam has a front wall, a rear wall, and an inner wall which extends between the front and rear walls along a major length of the crossbeam. The inner wall is hereby recessed to leave a gap in the area of the attachment zones. | 05-26-2011 |
