Abstract

A front end structure is provided for a vehicle that includes a bracket for attaching front crash sensors to the vehicle. The front end structure includes an engine compartment and a hood connected to the engine compartment by a hood latch and a pair of hinges. The bracket is connected to the hood latch and the front crash sensors to maintain palpability with the vehicle through the hood in a collision.

Claims

1. A sensor bracket for a vehicle having an engine compartment defining an airflow opening below a grille opening reinforcement, a hood and a hood latch, the sensor bracket comprising:

a band attached to the hood latch and being housed within the grille opening reinforcement and above the airflow opening; and

first and second front crash sensors attached to right and left ends of the band, respectively.

2. The sensor bracket of claim 1 wherein the vehicle includes a pair of longitudinal frame rails and a pair of fender wall supports, and wherein the right end and left end of the band are spaced from the pair of longitudinal frame rails and the pair of fender wall supports.

3. The sensor bracket of claim 2 wherein the band is attached to the grille opening reinforcement with the right end of the band and the left end of the band not being coextensive with a width of the grille opening reinforcement and the grille opening reinforcement spans a space between the band and the frame rails.

4. The sensor bracket of claim 2 wherein the band is attached to the grille opening reinforcement with the right end of the band and the left end of the band not being coextensive with a width of the grille opening reinforcement and the grille opening reinforcement spans a space between the band and the fender wall supports.

5. The sensor bracket of claim 1 wherein the grille opening reinforcement is formed from a material selected from the group consisting of:

carbon fiber reinforced plastic;

polypropylene;

ceramic; and

magnesium.

6. The sensor bracket of claim 1 wherein the band is formed from a material selected from the group consisting of:

steel;

stainless steel;

spring steel; and

aluminum.

7. The sensor bracket of claim 1 wherein the grille opening reinforcement includes an inner panel and an outer panel, and wherein the band is internally secured between the inner panel and the outer panel.

8. The sensor bracket of claim 1 wherein the first and second front crash sensors are disposed on the band in locations that are symmetrical relative to the hood latch.

9. The sensor bracket of claim 1 wherein the band is attached to the grille opening reinforcement above an airflow opening defined by the grille opening reinforcement and below the hood.

10. The sensor bracket of claim 1 wherein the band is configured to be attached to the hood latch in the center of the band for receiving the hood striker.

11. A front-end structure for a vehicle comprising:

an engine compartment defining an airflow opening;

a hood connected to the engine compartment by a hood latch and a pair of hinges;

a bracket connected to the hood latch above the airflow opening; and

a pair of front crash sensors attached to the bracket at laterally symmetrical locations, the sensors maintaining palpability with the vehicle through the hood in a collision.

12. The front-end structure of claim 11 further comprising;

a restraints control module operatively connected to the front crash sensors to receive data in the collision.

13. The front-end structure of claim 11 further comprising:

a pair of longitudinal frame rails and a pair of fender wall supports, and wherein right left ends of the bracket are spaced from the pair of longitudinal frame rails and the pair of fender wall supports.

14. The front-end structure of claim 11 wherein the bracket is connected to a grille opening reinforcement and the hood latch during normal operation of the vehicle, and wherein the bracket remains connected to the hood latch in a collision that destroys the grille opening reinforcement.

15. The front-end structure of claim 14 wherein the bracket is attached to the grille opening reinforcement with the right and left ends of the bracket not being coextensive with a width of the grille opening reinforcement, and wherein the grille opening reinforcement spans a space between the bracket and the frame rails.

16. The front-end structure of claim 14 wherein the bracket is attached to the grille opening reinforcement with the right and left ends of the bracket not being coextensive with a width of the grille opening reinforcement, and wherein the grille opening reinforcement spans a space between the bracket and the fender wall supports.

17. The front-end structure of claim 14 wherein the grille opening reinforcement includes an inner panel and an outer panel, and wherein the bracket is internally secured between the inner panel and the outer panel.

18. The front-end structure of claim 11 wherein the pair of front crash sensors are disposed on the bracket in locations that are symmetrical relative to the hood latch.

19. The front-end structure of claim 11 wherein the bracket is attached to a grille opening reinforcement above the airflow opening defined by the grille opening reinforcement.

20. The front-end structure of claim 11 wherein the bracket is configured to be attached to the hood latch disposed in the center of the bracket and is adapted to receive the hood striker.
