Embodiment Construction

[0032] figure 1 A side view of a vehicle 10 according to one embodiment of the invention is shown. The vehicle 10 includes a hood 12 , ie an element that covers the engine or box at the front of the vehicle and allows access to the engine compartment / box for maintenance and repair. The hood 12 may be made of steel, aluminum fiberglass, carbon fiber, or any other suitable material and may be hinged or otherwise attached to the vehicle at its rear or sides. The vehicle also includes a concealed hood latch in the area 14 indicated by the dashed circle, which is made of a high tensile strength material such as steel. However, the hidden hood latch need not be located in the area 14 at the front of the vehicle 10 and at the lateral center of the vehicle 10 .

[0033] The vehicle 10 extends along a transverse direction Y, a longitudinal direction X and a vertical direction Z.

[0034] figure 2 A schematic top view of a vehicle chassis 16 is shown, which includes two longitudinal ...

Abstract

Cross member (20) for a vehicle (10), which cross member (20) is arranged to extend substantially in the transverse (Y) direction of said vehicle (10) when mounted on a vehicle chassis (16) of said vehicle (10), and on which cross member (20) a first (26) of two mating mechanical parts, which are arranged to engage to fasten and / or lock a bonnet (12) of said vehicle (10), is arranged to be mounted in a designated position (P). An area in the vicinity of said designated position (P) comprises at least one mechanically weakened deformable portion (30) that is arranged to be more readily deformable than the majority of the remainder of said cross member (20) in the event of a collision with a pedestrian, said cross member (20) when said cross member (20) is mounted on said vehicle chassis (16) and subjected to an impact or compression force in the event of a collision with a pedestrian, whereby the deformation of said cross member (20) in the vicinity of said designated position (P) is facilitated and whereby said first mechanical part (26) is consequently arranged to be controllably displaced from its designated position (P) in the event of said collision.

Description

technical field [0001] The invention relates to a cross member for a vehicle and a vehicle comprising such a cross member. Background technique [0002] In a collision between a vehicle and a pedestrian, the pedestrian first hits the front of the vehicle and then hits the hood (hood) of the vehicle. While a vehicle hood can be designed to be relatively deformable, the engine covered by the hood is generally non-deformable, meaning that the deformability depends on the size of the gap between the hood and the engine. [0003] Regulations have come into effect in some countries in recent years which limit the severity of head injuries to pedestrians hit by vehicles. This will lead to more advanced hood designs, such as ones set up to use mechanical (spring force) or pyrotechnic devices to push their surface away from hard engine elements by a few centimeters during a collision with a pedestrian. [0004] For example, US Pat. No. 5,385,212 discloses a vehicle hood for a motor...
