Embodiment Construction

[0014] Figure 1 shows a view of an energy absorber 4 which, when combined with a reinforced bumper beam 6 and a vehicle panel 2, constitutes an energy absorbing bumper system for a vehicle. The bumper system is designed to protect pedestrians in collisions with a car's front bumper, or for low-speed, low-energy car collisions with solid structures. The energy absorber 4 is provided with a plurality of deformable protrusions 10, each protrusion 10 having a geometry that provides the desired function, which is adapted to enhance the deformability. The deformable protrusion 10 or the protrusion 10 mainly provides protection for the pedestrian's lower and / or upper legs during a collision. The deformable protrusion 10 deforms and absorbs energy during a collision. The energy absorption effect of the deformable protrusion 10 is suitable for reducing the force transmitted to the pedestrian's leg during a collision and the force transmitted to the vehicle components during a low-spee...

Abstract

The present invention relates to an energy absorber (4), which combines the protection on passers-by and automobiles into a front bumper system. The energy absorber includes an integral moulded glass cushion made of thermoplastic material, which is provided with a plurality of crushable convexes (10) protruding outwardly. The energy absorber is combined with an automobile sheet (2) and a reinforced beam (6) to form the automobile bumper system.

Description

technical field [0001] The present invention relates to an energy absorber that integrates pedestrian protection into the front bumper system of a motor vehicle. Background technique [0002] This application claims priority to US Application Serial No. 60 / 405,793, filed August 23, 2002, which is hereby incorporated by reference in its entirety. [0003] Future regulations in Japan and European countries may require an energy-absorbing design for vehicle bumper systems to help protect pedestrians' legs from collisions. [0004] Current bumper crash systems employ several separate components assembled. Typically, these components consist of a soft energy absorber supported by a rigid stiffener to meet the Federal Motor Vehicle Safety Standard FMVSS in the United States and the ECE42 crash regulations in Europe. The energy absorber components may be thermoplastic resin or polypropylene foam pieces adjacent to steel or aluminum rigid support reinforcement beams. Bumper assem...
