Abstract: A cross member for arrangement on a bumper system for a motor vehicle includes a single-piece open profile part made of uniform material and having a U-shaped cross section to define a first opening. The profile part has a curvature directed in a travel direction of the motor vehicle and includes a center zone having a second opening which is configured to point backwards in the travel direction, and end zones which have each an attachment area for a crash box and in which the first opening is configured to point forwards in the travel direction.

Abstract: A door impact beam for a motor vehicle includes a pot-shaped member made from a metal sheet and extending over a major part of a length of the beam to define two legs and a bridge interconnecting the legs. The bridge has a central length portion which is formed with an embossment defined by a depth, with a ratio of the depth of the embossment to a height of the pot-shaped member in midsection ranging between 1:3 and 1:6. The pot-shaped member has side flanges extending transversely from lower longitudinal edges of the legs in the central length portion.

Abstract: An automobile bumper arrangement includes a crossbeam coupled to side rails of an automobile via crash boxes, wherein the crossbeam has extensions disposed at end sections which are laterally supported on a corresponding crash box. A modular bumper system has a crossbeam, an extension and a crash box coupled to a side rail of an automobile, wherein the crossbeam has a standardized length and a vehicle-specific width of a bumper can be attained by varying the length of the extension.

Abstract: A bumper for the front or rear section of a motor vehicle includes a cross member having a shell of U shaped cross section so as to define two legs interconnected by a crosspiece, and a mounting plate joined to the shell. The mounting plate has a U shaped configuration to define a longitudinal wall and two flanged portions which extend from the wall in a direction of the shell so that passageways are formed between the legs of the shell and the flanged portions of the mounting plate. A buffer is disposed anteriorly of the cross member and constructed for a snap fit to the mounting plate, with the buffer having spring legs for acceptance in the passageways.

Abstract: A crash box for a motor vehicle includes an attachment portion which engages a longitudinal member of the motor vehicle and is secured thereto by at least one screw bolt which extends through a spacer sleeve. The spacer sleeve is securely fixed to the attachment portion and has two threaded portions of opposite pitch. Inserted from opposite sides of the spacer sleeve are tolerance compensating bolts, which are each provided with an inner rotary catch for interaction with an outer thread of the screw bolt. When the screw bolt is screwed in, the tolerance compensating bolts are thus moved apart until abutting against opposite inside wall surfaces of the longitudinal member. The screw bolt engages hereby a nut on an outside of the longitudinal member so that the attachment portion is now held without clearance on the longitudinal member by a head portion of the screw bolt and one of the tolerance compensating bolts, and by the other one of the tolerance compensating bolts and the nut.

Abstract: A motor-vehicle bumper assembly has a transverse rigid and U-shaped rail having an inner wall closely juxtaposed in a normal motor-vehicle travel direction with a frame of a motor vehicle, an outer wall spaced farther from the frame than the inner wall, and a horizontal wall extending between the inner and outer walls. Two crush cans spaced transversely apart support the rail on the motor-vehicle frame. Each can has a first U-section element extending in the direction and having an inner end fixed to the frame and an outer end fixed to the inner rail wall and a second U-section element nested with and mostly vertically offset from the respective first element and having an inner end fixed to the frame and an outer end extending past the inner rail wall. An outer mounting plate is fixed to the second-element outer end and to the outer rail wall.
