Abstract

A roof rack assembly for a vehicle having a roof is presented here. The roof rack assembly includes a first stanchion for structural attachment to the roof, a second stanchion for structural attachment to the roof, and a bar coupled between, and held above the roof by, the first stanchion and the second stanchion. The bar has a securing feature integrally formed therein, which holds an electric powered light-emitting component. Accordingly, the roof rack assembly employs a roof rack bar having a light-emitting element integrated therein.

Claims

1. A roof rack assembly for a vehicle having a roof and an electric power supply, the roof rack assembly comprising:

a front stanchion and a rear stanchion for structural attachment to the roof;

a bar having a front end coupled to the front stanchion such that the front stanchion maintains the front end above the roof and a rear end coupled to the rear stanchion such that the rear stanchion maintains the rear end above the roof, wherein the bar defines an axis extending from the rear end to the front end in a normal direction of vehicle travel, wherein the bar rotates about the axis for adjustment of an illumination direction perpendicular to the normal direction of travel;

an illumination element integrated with the bar and extending without interruption between the stanchions to illuminate in the illumination direction from the front stanchion to the rear stanchion; and

an illumination electronics module to drive the illumination element, the illumination electronics module being powered by the electric power supply of the vehicle.

2. The roof rack assembly of claim 1, wherein the bar forms a C-shaped channel extending in the normal direction of vehicle travel without interruption between the front stanchion and the rear stanchion, and wherein the illumination element is positioned in the C-shaped channel.

3. The roof rack assembly of claim 2, wherein the illumination element has a front end received in the front stanchion and a rear end received in the rear stanchion, and wherein the front stanchion and the rear stanchion block illumination in the normal direction of travel and the direction opposite the normal direction of travel.

4. The roof rack assembly of claim 3, wherein the illumination element comprises:

an illumination tube integrated with the bar; and

a light-emitting element to illuminate the illumination tube.

5. The roof rack assembly of claim 4, wherein the light-emitting element is housed within the front stanchion.

6. The roof rack assembly of claim 1, wherein the illumination electronics module drives the illumination element in response to turn signal indicator commands of the vehicle.

7. The roof rack assembly of claim 1, wherein the illumination electronics module drives the illumination element in response to remote key fob commands received at the vehicle.

8. The roof rack assembly of claim 1, wherein the illumination electronics module drives the illumination element in response to user manipulation of an onboard user interface element of the vehicle.

9. A roof rack assembly for a vehicle having a roof, the roof rack assembly comprising:

a front stanchion for structural attachment to the roof;

a rear stanchion for structural attachment to the roof;

a bar coupled between, and held above the roof by, the front stanchion and the rear stanchion, the bar having a channel integrally formed therein and extending in the normal direction of vehicle travel without interruption between the front stanchion and the rear stanchion;

an electric powered light-emitting component attached to the bar and held within the channel, wherein the light-emitting component has a front end received in the front stanchion and a rear end received in the rear stanchion, and wherein the front stanchion and the rear stanchion block illumination in the normal direction of travel and the direction opposite the normal direction of travel;

a front rotation mechanism for the front stanchion; and

a rear rotation mechanism for the rear stanchion, wherein the front rotation mechanism and the rear rotation mechanism rotatable couple the bar to the front stanchion and the rear stanchion to accommodate rotatable adjustment about an axis extending in the normal direction of vehicle travel of an illumination direction of the electric powered light-emitting component.

10. The roof rack assembly of claim 9, wherein the electric powered light-emitting component comprises:

a flexible illumination tube; and

a light-emitting element to illuminate the flexible illumination tube.

11. The roof rack assembly of claim 10, wherein the light-emitting element is housed within the front stanchion or the rear stanchion.

12. The roof rack assembly of claim 9, further comprising an illumination electronics module to drive the electric powered light-emitting component, the illumination electronics module being powered by an onboard power supply of the vehicle.

13. The roof rack assembly of claim 12, wherein the illumination electronics module controls operation of the electric powered light-emitting component in response to remote key fob commands received at the vehicle.

14. The roof rack assembly of claim 12, wherein the illumination electronics module controls operation of the electric powered light-emitting component in response to user manipulation of an onboard user interface element of the vehicle.

15. A vehicle comprising:

a roof;

a first front stanchion attached to and supported by the roof;

a first rear stanchion attached to and supported by the roof;

a first light-emitting roof rack bar rotatably coupled between, and held above the roof by, the first front stanchion and the first rear stanchion, wherein the first light-emitting roof rack bar defines a first axis extending in a normal direction of vehicle travel, and wherein the first light-emitting roof rack bar rotates about the first axis for adjustment of a first illumination direction perpendicular to the normal direction of travel;

a first illumination electronics module to drive the first light-emitting roof rack bar; and

an onboard power supply to provide operating power to the first illumination electronics module.

16. The vehicle of claim 15, wherein the first light-emitting roof rack bar forms a first C-shaped channel extending in the normal direction of vehicle travel, the vehicle further comprising a first illumination element secured within the first C-shaped channel of the first light-emitting roof rack bar to illuminate in the first illumination direction.

17. The vehicle of claim 16, wherein the first C-shaped channel and the first illumination element extend without interruption between the first front stanchion and the first rear stanchion to illuminate in the first illumination direction from the first front stanchion to the first rear stanchion.

18. The vehicle of claim 17, wherein the first illumination element has a front end received in the first front stanchion and a rear end received in the first rear stanchion, and wherein the first front stanchion and the first rear stanchion block illumination in the normal direction of travel and the direction opposite the normal direction of travel.

19. The vehicle of claim 18 further comprising:

a second front stanchion attached to and supported by the roof;

a second rear stanchion attached to and supported by the roof;

a second light-emitting roof rack bar rotatably coupled between, and held above the roof by, the second front stanchion and the second rear stanchion, wherein the second light-emitting roof rack bar defines a second axis extending in a normal direction of vehicle travel, wherein the second light-emitting roof rack bar rotates about the second axis for adjustment of a second illumination direction perpendicular to the normal direction of travel, wherein the second light-emitting roof rack bar forms a second C-shaped channel extending in the normal direction of vehicle travel without interruption between the second front stanchion and the second rear stanchion;

a second illumination element secured within the second C-shaped channel of the second light-emitting roof rack bar and extending without interruption between the second front stanchion and the second rear stanchion to illuminate in the second illumination direction from the second front stanchion to the second rear stanchion, wherein the second illumination element has a front end received in the second front stanchion and a rear end received in the second rear stanchion, and wherein the second front stanchion and the second rear stanchion block illumination in the normal direction of travel and the direction opposite the normal direction of travel; and

a second illumination electronics module to drive the second light-emitting roof rack bar, wherein the onboard power supply provides operating power to the second illumination electronics module.
