Abstract

A combined rear exterior lamp and cleaning system including: a lens for the rear exterior lamp of the vehicle, the lens has an inner surface and an outer surface, a cleaning arrangement for providing a cleaning fluid to an exterior surface of the rear window, an inlet connectable to a cleaning fluid hose for providing cleaning fluid to the cleaning arrangement. The cleaning arrangement includes a channel generally parallel with at least one of the lens inner surface or the lens outer surface, and an array of outlets in fluid communication with the channel. The channel is attached to the lens and is adapted to transport the cleaning fluid from the inlet to the array of outlets located on the outer side of the lens for providing the cleaning fluid to the rear window.

First claim

The invention claimed is:

1. A combined rear exterior lamp and cleaning system for cleaning a rear window of a vehicle, the combined rear exterior lamp and cleaning system comprising:
a lens for the rear exterior lamp of the vehicle, the lens extending in a side-to-side direction of the vehicle and having an inner surface and an outer surface, the inner surface adapted to face a light source for the rear lamp,
a cleaning arrangement for providing a cleaning fluid to an exterior surface of the rear window,
an inlet connectable to a cleaning fluid hose for providing cleaning fluid to the cleaning arrangement, the inlet arranged on the same side of the lens as the inner surface,
wherein the cleaning arrangement comprises a channel member defining a channel that is disposed in a through-opening through the lens that runs parallel to both the inner surface and the outer surface of the lens and extends in a side-to-side direction of the lens that corresponds to the side-to-side direction of the vehicle and an array of outlets in fluid communication with the channel of the channel member and extending at an angle from the channel to the outer surface of the lens, wherein the channel runs between adjacent outlets of the array of outlets from a first side of the lens to a second side of the lens, and wherein the channel is embedded in and the array of outlets are formed through a material of the channel member and are adapted to transport the cleaning fluid from the inlet, along the outer surface of the lens in the side-to-side direction of the lens, to each of the array of outlets from the first side of the lens to the second side of the lens, and to the rear window of the vehicle through the outer surface of the lens, and the channel member and the lens formed with a same material.

2. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the lens comprises the through-opening from the inner surface to the outer surface, wherein the cleaning arrangement is releasably attached in the through-opening to seal the through-opening.

3. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the array of outlets is distributed from a first end portion to a second end portion of the channel.

4. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the outlets of the array of outlets are evenly spread along the channel.

5. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the spacing between outlets in a first subset of outlets is different from the spacing between outlets in a second subset of outlets.

6. The combined rear exterior lamp and cleaning system according to claim 1 , wherein a longitudinal axis of the outlets from the channel intercepts with the rear window of the vehicle.

7. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the length of the channel is at least half the side-to-side distance of the outer surface of the lens.

8. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the channel comprises at least two segments in fluid communication with each other, each segment having respective outlets, wherein an axis along one of the channel segments intercepts an axis along another one of the channel segments.

9. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the rear exterior lamp comprises a housing for accommodating a light source holder for the light source, wherein the lens is adapted to seal an opening in the housing.

10. The combined rear exterior lamp and cleaning system according to claim 1 , comprising a hose and a cleaning fluid container, wherein the hose is connectable to the inlet for providing a cleaning fluid to the inlet from the cleaning fluid container arranged for holding a reservoir of cleaning fluid.

11. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the rear exterior lamp is arranged above the rear window.

12. The combined rear exterior lamp and cleaning system according to claim 1 , wherein the rear exterior lamp is a center high mount stop lamp.

13. A vehicle, comprising:
a rear window; and
a combined rear exterior lamp and cleaning system for cleaning the rear window of the vehicle, the combined rear exterior lamp and cleaning system comprising:
a lens for the rear exterior lamp of the vehicle, the lens extending in a side-to-side direction of the vehicle and having an inner surface and an outer surface, the inner surface adapted to face a light source for the rear lamp,
a cleaning arrangement for providing a cleaning fluid to an exterior surface of the rear window,
an inlet connectable to a cleaning fluid hose for providing cleaning fluid to the cleaning arrangement, the inlet arranged on the same side of the lens as the inner surface,
wherein the cleaning arrangement comprises a channel member defining a channel that is disposed in a through-opening through the lens that runs parallel to both the inner surface and the outer surface of the lens and extends in a side-to-side direction of the lens that corresponds to the side-to-side direction of the vehicle and an array of outlets in fluid communication with the channel of the channel member and extending at an angle from the channel to the outer surface of the lens, wherein the channel runs between adjacent outlets of the array of outlets from a first side of the lens to a second side of the lens, and wherein the channel is embedded in and the array of outlets are formed through a material of the channel member and are adapted to transport the cleaning fluid from the inlet, along the outer surface of the lens in the side-to-side direction of the lens, to each of the array of outlets from the first side of the lens to the second side of the lens, and to the rear window of the vehicle through the outer surface of the lens, and the channel member and the lens formed with a same material.
