Embodiment Construction

[0028] figure 1 Schematically shows a vehicle rear assembly 100 with a vehicle rear trim body 102 , a bumper cross member 10 with a hollow profile body 12 and an air channel 106 formed by a channel body 104 , which runs from the roof side of the vehicle The inlet opening 108 on the upper body extends to the outlet opening 110 on the vehicle rear trim 102 .

[0029] The vehicle rear assembly 100 has a second air duct 114 guided via a duct body 112 so that two air ducts 106 , 114 are provided parallel to each other and arranged symmetrically with respect to the central longitudinal axis of the vehicle, each via the duct body 104 , 112 guides and passes from inlet openings 108, 115 into outlet openings 110, 116.

[0030] figure 2 A longitudinal section of the vehicle rear assembly 100 in the region of the air channel 106 is shown. The air duct 106 formed by the duct body 104 extends from the inlet opening 108 to the outlet opening through an air-cooled cooling device 118 inte...

Abstract

A bumper crossmember (10) for a vehicle, with a hollow profile body (12) which has a vehicle frame-side proximal vertical wall (20) and a distal vertical wall (22) which are connected to one another by way of transverse walls and extend along a vertical direction (16). The transverse walls laterally delimit hollow chambers (26) which are arranged in the hollow profile body. The center longitudinal direction of the hollow chambers (26) are oriented in each case along the vertical direction (16) and the hollow chambers (26) are open on the end side.

Description

technical field [0001] The invention relates to a bumper beam for a vehicle. Furthermore, the invention relates to a vehicle rear assembly with such a bumper cross member. Background technique [0002] DE 10 2016 113 883 A1 discloses a bumper beam for a motor vehicle, the lower transverse wall of which is inclined and is therefore adapted to an air channel guided alongside it. This results in a high installation space requirement for the components. Furthermore, bottlenecks may arise in the air ducts in the region of the bumper beam of the motor vehicle. Contents of the invention [0003] The object of the invention is to provide an improved bumper beam compared to this. [0004] The object of the invention is achieved by a bumper beam according to claim 1 . [0005] Bumper beams are used in vehicles, especially motor vehicles. The bumper cross member has a hollow profile body with frame-side proximal and distal vertical walls, which are connected to one another by tr...
