Embodiment Construction

[0038] figure 1 A schematic side view showing the low-speed crash test protocol. The figure schematically shows a structure according to the National Highway Traffic Safety Administration (NHTSA) Code of Federal Regulations 49 CFR Part 581. This standard specifies the performance requirements for passenger cars in low-speed front-to-rear collisions. This specific structure was used to test the bodywork and safety related equipment at a 2.5mph guardrail impact speed of a longitudinal rear pendulum impact. The standard requires that safety-related components and exterior surfaces (eg, sheet metal; lights) not involved in the bumper system be damaged without damage to the face material and its fasteners by means of a pendulum impact test at a speed of 2.5 mph.

[0039] figure 1 A vehicle 10 is shown, wherein a rear end 11 of the vehicle is provided with rear lights 12 . The lower portion of the end portion of the vehicle 10 is provided with a bumper 13 . During the test, the...

Abstract

The invention relates to a vehicle light unit and a vehicle. The invention relates to the light unit on an automotive vehicle, which light unit makes up an assembly adapted for attachment to the vehicle. The light unit comprises a translucent body attached to the assembly, said translucent body having a outer surface defining a light emitting area, an inner surface facing the vehicle, and side surfaces connecting the outer and inner surfaces. At least one mounting section is provided for a light source arranged to transmit light into said translucent body, and attachment means for attaching a support or housing to a side surface or a rear surface of said translucent body. The translucent body forms a wave guide arranged to direct and disperse light from at least one light source through said translucent body so as to provide illumination through the light emitting area; and which body comprises a shock absorbing elastic material.

Description

technical field [0001] The present invention relates to vehicle lights, and more particularly to vehicle light assemblies that are elastically deformable upon impact with an object. The invention further relates to vehicle lights arranged to help streamline the vehicle body thereby reducing aerodynamic drag. Background technique [0002] As vehicles become increasingly aerodynamically designed, it is desirable to provide indicator and rear light assemblies that are integrated into body and vehicle bumpers to provide sleek, smooth, aerodynamic styling. However, when the light assembly is substantially flush with either vehicle bumper, a collision with a foreign object or by another bumper will result in damage to the light assembly. Current lamp assemblies typically employ a functional bulb reflector which in turn is surrounded by what is known as a "light" frame or housing which is a tough heat resistant material such as nylon metallized with aluminum or polycarbonate to f...
