Embodiment Construction

[0033] figure 1 A plan view of the bumper unit 1 of the vehicle during a collision with a fixed obstacle 20 is shown. A typical SORB crash situation is shown here, in which the fixed obstacle 20 is only hit by a relatively small side area of ​​the vehicle. The bumper unit 1 comprises a bumper 2 which extends substantially along the Y-axis of the vehicle and which is welded to two crush elements, which in the present case are designed as crush units 3 . The crush unit 3 extends substantially along the X-axis. Each crush unit 3 is correspondingly welded to a web 4 which is used to attach the entire bumper unit 1 to a longitudinal element of the vehicle (not shown). The illustrated crash situation should be considered purely illustrative, as a situation in which the advantages of the invention come into effect. In the illustrated case, the crush unit 3 arranged at the end of the bumper unit 1 remote from the obstacle 20 is subjected to a special type of load. Here, in particu...

Abstract

The invention relates to a bumper unit (1) for a motor vehicle with a crush unit (3) for attachment to a bumper (2) and with a connection plate (4) for connection to a vehicle structure , the connection plate is connected to the crush unit (3) by at least one main weld (5.1, 5.2, 5.3). In order to make it possible for the bumper unit to have an improved crash behavior, it is conceivable according to the invention that at least one reinforcing element (7, 8) is adjacent to the main weld seam (5.1, 5.2, 5.3) and away from the main weld seam ( 5.1, 5.2, 5.3) are connected to the crush unit (3) in the extended connecting region (3.5).

Description

technical field [0001] The invention relates to a bumper unit for a motor vehicle. Background technique [0002] In modern motor vehicles, an important aspect in the planning process is the design of crumple zones, ie those areas where the vehicle absorbs energy through deformation in an accident and thus protects other vehicle areas and especially prevents occupants from damage or injury or part. Essential components here are bumpers, which are arranged at the front and rear in the direction of travel and extend substantially transversely to the direction of travel. In typical design concepts, the actual bumper is connected to the vehicle chassis via energy absorbing elements such as crash boxes, crash tubes or crush units. In this case, the bumper itself has a more robust design due to its shaping and / or the materials used, while the energy absorbing element extending approximately in the direction of travel is less robust. These may for example consist of aluminum or a...
