Problems solved by technology

However, the resistance of the crossbeam increases when the lower beam part is also subjected to deformation or when the rear section of the upper beam part is also deformed, said rear section being oriented almost parallel to the direction of impact and thus with a greater resistance against deformation
This makes it difficult to comply with the limit values ​​to which the HIC (Head Injury Critierium) applies when hitting a known beam

Embodiment Construction

[0024] figure 1 A perspective view of a part of a motor vehicle body to which the invention is applicable is shown. The rear area of ​​the bonnet 1 and the window adjoining it, which accommodates the windshield in the completed motor vehicle and flanked by A-pillars 2 , can be seen. exist figure 1 The instrument panel lining has been removed in , so that the instrument panel interior part 3 lying thereunder and the cross member 4 formed from a single-layer blank can be shown, which are hidden under the instrument panel lining in the finished car. The rear edge 5 of the cross member 4 rests on the upper edge of the partition, which extends between the passenger compartment and the engine compartment. The front edge 6 of the cross member 4 supports the front lower edge of the front windshield.

Abstract

The present invention relates to a motor vehicle body. The motor vehicle body includes, but is not limited to a front hood (1), a windshield (22) rising from a rear edge of the front hood and a cross member (4) substantially extending over the width of the windshield (22), of which a front edge (6) supports a front lower edge (5) of the windshield (22) and a rear edge (5) is supported on a structural element (23) of the body. A top side of the cross member (4) faces the passenger cell and a bottom side faces the engine compartment. Between the front edge (6) and the rear edge (5) of the cross member (4) comprises at least one first region (11, 17, 21), in which the top side is concavely curved in a section plane running in vehicle longitudinal direction and which yields to a load by intensifying the curvature along an apex line (15) yielding towards the engine compartment and pivoting of two zones (13, 14) extending on both sides of the apex line (15) towards each other.

Description

technical field [0001] The invention relates to a front cover, a front windshield rising gradually from the rear edge of the front cover, and a beam supporting the front lower edge of the front windshield. Background technique [0002] A motor vehicle is known from DE 10 2007 012 830 A1 in which the cross member supporting the windshield consists of two cross members connected to each other at their front and rear edges. The upper beam part is curved upwards in cross-sectional view, has a front section that supports the front edge of the front windshield and rises counter to the direction of travel, an essentially horizontal middle section and a steep slope counter to the direction of travel Downwardly extending rear section. When the motor vehicle hits a pedestrian in an accident, the pedestrian usually falls obliquely from above on the bonnet, the pedestrian rolling about an axis approximately at the front edge of the bonnet. In this case, for an adult pedestrian of norm...
