Abstract

An automotive vehicle includes a body having fore and aft portions. The vehicle includes a bumper beam coupled to the vehicle body proximate the fore portion and a heat exchanger disposed aft of the bumper beam. A fascia assembly is coupled to the vehicle body and extends about the bumper beam. The fascia assembly includes a fascia inlet configured to direct an airflow from the exterior of the fascia assembly to the interior of the fascia assembly. An energy absorption member is disposed between the fascia and the bumper beam. An air passage extends through at least one of the bumper beam and the energy absorption member. The air passage extends from an air passage inlet to an air passage outlet. The air passage inlet is positioned downstream of the fascia inlet with respect to the airflow, and the air passage outlet being positioned upstream of the heat exchanger.

First claim

What is claimed is:

1. An automotive vehicle comprising:
a vehicle body having a fore portion and an aft portion;
a bumper beam coupled to the vehicle body proximate the fore portion;
a heat exchanger disposed aft of the bumper beam;
a fascia assembly coupled to the vehicle body and extending about the bumper beam, the fascia assembly including a fascia inlet configured to direct an airflow from the exterior of the fascia assembly to the interior of the fascia assembly;
an energy absorption member disposed between the fascia and the bumper beam; and
an air passage extending through at least one of the bumper beam and the energy absorption member, the air passage extending from an air passage inlet to an air passage outlet, the air passage inlet being positioned downstream of the fascia inlet with respect to the airflow, the air passage outlet being positioned upstream of the heat exchanger.

2. The automotive vehicle of claim 1 , wherein the energy absorption member includes a first surface, a second surface, and a body extending from the first surface to the second surface, the air passage inlet being disposed at the first surface, the air passage outlet being disposed at the second surface.

3. The automotive vehicle of claim 2 , wherein the first surface is a lower surface, and wherein the second surface is an upper surface.

4. The automotive vehicle of claim 1 , wherein the bumper beam includes a first surface, a second surface, and a body extending from the first surface to the second surface, the air passage inlet being disposed at the first surface, the air passage outlet being disposed at the second surface.

5. The automotive vehicle of claim 4 , wherein the first surface is a fore surface, and wherein the second surface is an upper surface.

6. The automotive vehicle of claim 4 , wherein the bumper beam extends laterally from a first side of the vehicle to a second side of the vehicle, the bumper beam comprising a plurality of lateral rib members, wherein at a first lateral portion of the bumper beam a web extends between the plurality of lateral rib members, and wherein at a second portion of the bumper beam no web extends between the plurality of rib members, the air passage inlet and the air passage outlet being defined at the second portion.

7. The automotive vehicle of claim 1 , wherein the energy absorption member includes a first surface, the bumper beam includes a second surface, the air passage inlet is disposed at the first surface, and the air passage outlet is disposed at the second surface.

8. The automotive vehicle of claim 1 , wherein the air passage is sized to receive 30% of airflow through the fascia inlet.

9. A bumper assembly comprising:
a bumper beam;
a fascia assembly extending about the bumper beam, the fascia assembly including a fascia inlet configured to direct an airflow from the exterior of the fascia assembly to the interior of the fascia assembly;
an energy absorption member disposed between the fascia and the bumper beam; and
an air passage extending through at least one of the bumper beam and the energy absorption member, the air passage extending from an air passage inlet to an air passage outlet, the air passage inlet being positioned downstream of the fascia inlet with respect to the airflow and being sized to receive between 20% and 40% of the airflow.

10. The bumper assembly of claim 9 , wherein the energy absorption member includes a first surface, a second surface, and a body extending from the first surface to the second surface, the air passage inlet being disposed at the first surface, the air passage outlet being disposed at the second surface.

11. The bumper assembly of claim 10 , wherein the first surface is a lower surface, and wherein the second surface is an upper surface.

12. The bumper assembly of claim 9 , wherein the bumper beam includes a first surface, a second surface, and a body extending from the first surface to the second surface, the air passage inlet being disposed at the first surface, the air passage outlet being disposed at the second surface.

13. The bumper assembly of claim 12 , wherein the first surface is a fore surface, and wherein the second surface is an upper surface.

14. The bumper assembly of claim 12 , wherein the bumper beam extends laterally from a first side of a vehicle to a second side of a vehicle, the bumper beam comprising a plurality of lateral rib members, wherein at a first lateral portion of the bumper beam a web extends between the plurality of lateral rib members, and wherein at a second portion of the bumper beam no web extends between the plurality of rib members, the air passage inlet and the air passage outlet being defined at the second portion.

15. The bumper assembly of claim 9 , wherein the energy absorption member includes a first surface, the bumper beam includes a second surface, the air passage inlet is disposed at the first surface, and the air passage outlet is disposed at the second surface.

16. The bumper assembly of claim 9 , wherein the air passage is sized to receive 30% of airflow through the fascia inlet.
