Abstract

A vehicle bumper assembly may include a fascia, a bumper beam arranged inside of the fascia including an upper portion and a lower portion, and a reinforcement block arranged only on the upper portion of the bumper beam and configured to absorb energy and to eliminate contact of the upper portion with the fascia during a collision.

First claim

What is claimed is:

1. A vehicle bumper assembly, comprising:
a fascia;
a bumper beam arranged inside of the fascia including an upper bumper portion and a lower bumper portion; and
an L-shape strip arranged on -the upper bumper portion, the strip including a fillet extending from an inner corner of the strip and increasing thickness at the inner corner to absorb energy to engage a chamfered edge defined by the upper portion of the bumper beam.

2. The vehicle bumper assembly of claim 1 , wherein the L-shape strip is arranged across a portion of the upper bumper.

3. The vehicle bumper assembly of claim 1 , wherein the L-shape strip is arranged on a front face of the bumper beam.

4. The vehicle bumper assembly of claim 3 , wherein the bumper beam defines a chamfered edge extending across the upper portion of the bumper beam.

5. The vehicle bumper assembly of claim 1 , wherein the L-shape strip comprises a foam polymer material.

6. The vehicle bumper assembly of claim 1 , wherein the L-shape strip comprises an aluminum hex block.

7. A reinforcement block for a vehicle bumper assembly, comprising:
an inverted L-shape body assembly configured to be arranged only on an upper portion of a bumper beam to inhibit the upper portion from contacting a fascia panel during a collision, and
a projection extending outwardly from an inner side of the body to increase a thickness of the body assembly towards the upper portion to serve as a spacer from colliding objects and engaging a chamfered edge defined by the upper portion of the bumper beam to serve as a spacer.

8. The reinforcement block of claim 7 , wherein the body is arranged across a portion of the upper portion of the bumper beam.

9. The reinforcement block of claim 7 , wherein the body is arranged on a front face of the bumper beam.

10. The reinforcement block of claim 7 , wherein the body comprises a foam material.

11. The reinforcement block of claim 7 , wherein the body comprises an aluminum hex block.

12. A reinforcement block for a vehicle bumper assembly, comprising:
an inverted L-shape elongated strip configured to be arranged on a top corner of a bumper beam to prevent contact between the top corner and a fascia panel during a collision, the elongated strip including a fillet extending from an inner side at an inner corner of the elongated strip to increase a thickness of the strip towards the top corner of the bumper beam to serve as a spacer from colliding objects and engaging a chamfered edge defined by the bumper beam.

13. The reinforcement block of claim 12 , wherein the elongated strip is arranged across a portion of the bumper beam.

14. The reinforcement block of claim 12 , wherein the elongated strip is arranged on a front face of the bumper beam.

15. The reinforcement block of claim 12 , wherein the elongated strip comprises a foam material.

16. The reinforcement block of claim 12 , wherein the elongated strip comprises an aluminum hex block.
