Abstract

A step assembly of a vehicle is provided herein. A step pad is pivotally coupled to a quarter panel of the vehicle and is movable between a stowed position and deployed position. At least one light source is provided in the step pad and the step pad transmits light emitted by the at least one light source in an outward direction.

Claims

1. A step assembly of a vehicle comprising:

a step pad pivotally coupled to a quarter panel of the vehicle and movable between a stowed position and deployed position; and

at least one light source provided in the step pad, wherein the step pad transmits light emitted by the at least one light source in an outward direction, and wherein the at least one light source is operated based on whether someone is detected to be standing on a step area of the step pad through the use of a strain gauge.

2. The step assembly of claim 1, wherein light emitted by the at least one light source is transmitted through a side portion of the step pad to produce one of a sconce lighting against a side of the vehicle and an outward-vehicle illumination based on the step pad being in one of the stowed and deployed position.

3. The step assembly of claim 1, wherein light emitted by the at least one light source is transmitted through a step area of the step, the step area defining a top portion of the step pad when the step pad is in the deployed position.

4. The step assembly of claim 1, wherein light emitted by the at least one light source is transmitted through a side portion of the step pad to illuminate a wheel well space of the vehicle when the step pad is in the stowed position.

5. The step assembly of claim 1, wherein light emitted by the at least one light source is transmitted through a bottom portion of the step pad to produce one of a vehicle-outward illumination and a downward directional lighting toward a ground surface based on the step pad being in one of the stowed and deployed position.

6. The step assembly of claim 1, further comprising a plurality of contacts that are mated to one another when the step pad is in the stowed position and are configured to inductively charge an energy storage device disposed inside the step pad and operably connected to the at least one light source.

7. A step assembly of a vehicle, comprising:

an arched step pad pivotally coupled to a rear quarter panel of the vehicle and movable between a stowed position covering a wheel well trim member and a deployed position substantially parallel with a ground surface;

at least one light source provided in the step pad, wherein the step pad transmits light emitted by the at least one light source in an outward direction; and

a plurality of contacts that are mated to one another when the step pad is in the stowed position and are configured to inductively charge an energy storage device disposed inside the step pad and operably connected to the at least one light source.

8. The step assembly of claim 7, wherein light emitted by the at least one light source is transmitted through a side portion of the step pad to produce one of a sconce lighting against a side of the vehicle and an outward-vehicle illumination based on the step pad being in one of the stowed and deployed position.

9. The step assembly of claim 7, wherein light emitted by the at least one light source is transmitted through a step area of the step, the step area defining a top portion of the step pad when the step pad is in the deployed position.

10. The step assembly of claim 7, wherein light emitted by the at least one light source is transmitted through a side portion of the step pad to illuminate a wheel well space of the vehicle when the step pad is in the stowed position.

11. The step assembly of claim 7, wherein light emitted by the at least one light source is transmitted through a bottom portion of the step pad to produce one of a vehicle-outward illumination and a downward directional lighting toward a ground surface based on the step pad being in one of the stowed and deployed position.

12. The step assembly of claim 7, wherein the at least one light source is operated based on whether someone is detected to be standing on a step area of the step pad through the use of a strain gauge.

13. A step assembly of a vehicle comprising:

a step pad pivotally coupled to a quarter panel of the vehicle and movable between a stowed and deployed position, the step pad including at least one portion configured to luminesce in response to excitation light by at least one light source, wherein the at least one light source is provided on a printed circuit board disposed inside the step pad.

14. The step assembly of claim 13, wherein the step pad is hinged to a rear quarter panel of the vehicle and covers a wheel well trim member when in the stowed position and is substantially parallel with a ground surface when in the deployed position.

15. The step assembly of claim 13, wherein the step pad includes a photoluminescent structure having long-persistence phosphors configured to store the excitation light and continue to luminesce for a period of time once the excitation light ceases to be provided.

16. The step assembly of claim 13, wherein the step pad includes a top portion, a bottom portion, and side portions, each configured to luminesce singly or in combination based on the step pad being in one of the stowed and deployed positions.

17. The step assembly of claim 13, further comprising a controller in communication with at least one sensor to control an operational state of the at least one light source, wherein the at least one sensor includes one of a magnetic sensor, a proximity sensor, a capacitive sensor, an accelerometer, and a strain gauge.
