Vehicle headlamp assembly

1. A vehicle body comprising:

a fender; and

a headlamp assembly defining a generally horizontal, upwardly exposed and unobstructed surface, and being movably mounted with respect to the fender such that the headlamp assembly moves from a first position to a second position in response to a load having a downward component acting on the surface;

wherein the headlamp assembly includes a member sufficiently positioned to receive a reaction force from the fender in response to the load having a downward component; and

wherein the member is characterized by a strength discontinuity at which the member breaks when the reaction force exceeds a predetermined amount.

2. The vehicle body of claim 1 , wherein a portion of the headlamp assembly extends over a portion of the fender.

3. The vehicle body of claim 1 , wherein the headlamp assembly is configured to rotate with respect to the fender in response to the load.

4. The vehicle body of claim 1 , wherein the headlamp assembly includes a lens, and wherein the lens defines the surface.

5. The vehicle body of claim 1 , wherein the member includes a clip portion; wherein the clip portion is connected to the lens; and wherein the clip is configured to shear when the reaction force exceeds a predetermined value.

6. The vehicle of claim 1 , wherein the member is a portion of the lens; and wherein the lens includes a locally weakened segment configured to deform when the reaction force exceeds a predetermined value.

7. The vehicle of claim 1 , wherein the member is mounted with respect to the lens by a heat stake, and wherein the heat stake is configured to break when the reaction force exceeds a predetermined value.

8. The vehicle of claim 1 , wherein the member comprises a material having a lower strength or modulus than the lens.

9. The vehicle of claim 1 , wherein the lens and the fender define a gap therebetween; and wherein the member at least partially conceals the gap.

10. The vehicle of claim 1 , wherein the member is configured such that the member absorbs energy from the load having a downward component.

11. A headlamp assembly for a vehicle body having a fender, the headlamp assembly comprising:

a lens defining a surface, the headlamp assembly being mountable to the body such that the surface is upwardly exposed and unobstructed and such that the lens moves with respect to the fender in response to a load having a vertical component being applied to the surface; and

a member being mounted to the lens such that the member receives a reaction force from the fender when the lens moves in response to the load;

wherein the member is configured to deform when the reaction force exceeds a predetermined value; and

wherein the member is a portion of the lens; and wherein the lens includes a locally weakened segment configured to deform when the reaction force exceeds a predetermined value.

12. The headlamp assembly of claim 11 , wherein the member comprises a material having a lower strength or modulus than the lens.

13. A headlamp assembly for a vehicle body having a fender, the headlamp assembly comprising:

a lens defining a surface, the headlamp assembly being mountable to the body such that the surface is upwardly exposed and unobstructed and such that the lens moves with respect to the fender in response to a load having a vertical component being applied to the surface; and

a member being mounted to the lens such that the member receives a reaction force from the fender when the lens moves in response to the load;

wherein the member is configured to deform when the reaction force exceeds a predetermined value; and

wherein the member is mounted with respect to the lens by a heat stake, and wherein the heat stake is configured to break when the reaction force exceeds a predetermined value.
