Abstract

A vehicular illumination mechanism is mountable on a vehicle having a loading and unloading mechanism for moving a wheelchair between the vehicle and a road surface. The loading and unloading mechanism has an upper face portion and is movable between a stored position and an extended position. The vehicular illumination mechanism includes a position detection portion that is configured to detect a position of the loading and unloading mechanism, an illuminating lamp that is configured to illuminate the upper face portion of the loading and unloading mechanism extended to the extended position, and an illumination control portion that is configured to light the illuminating lamp when the position detection portion detects that the loading and unloading mechanism is in the extended position.

First claim

What is claimed is:

1. A vehicular illumination mechanism that is mountable on a vehicle having a loading and unloading mechanism for moving a wheelchair between the vehicle and a road surface, wherein:
the loading and unloading mechanism has an upper face portion where the wheelchair can pass or be placed, and is movable between a stored position where the loading and unloading mechanism is stored in a vicinity of a doorway of a vehicle body of the vehicle and an extended position where a level difference between the upper face portion and the road surface is minimum, and
the vehicular illumination mechanism comprises:
a position detection portion that is configured to detect a position of the loading and unloading mechanism;
an illuminating lamp that is configured to illuminate the upper face portion of the loading and unloading mechanism extended to the extended position;
an illumination control portion that is configured to light the illuminating lamp when the position detection portion detects that the loading and unloading mechanism is in the extended position; and
a door lamp mounted on a peripheral portion of a sliding door at a vehicle rear side thereof, the sliding door provided so as to be openable and closable at the doorway,
wherein the illumination control portion is configured to light or blink the door lamp when the loading and unloading mechanism is extended to the extended position, and
the door lamp is mounted with a light emitting surface on the sliding door facing rearward of the vehicle, the sliding door being configured to open and close the doorway by moving in a front-rear direction of the vehicle along an outer face of the vehicle body of the vehicle, and
wherein the illuminating lamp is configured to illuminate the upper face portion of the loading and unloading mechanism so as to display a movement line corresponding to an appropriate movement path where the wheelchair is to move at a time of loading and unloading by a linear illumination.

2. The vehicular illumination mechanism according to claim 1 , further comprising:
a vehicle interior illuminating lamp configured to illuminate a vehicle interior in the vicinity of the doorway, wherein:
the illumination control portion is configured to light the vehicle interior illuminating lamp when the loading and unloading mechanism is extended to the extended position.

3. The vehicular illumination mechanism according to claim 1 , wherein:
the illumination control portion is configured to turn off the door lamp when it is detected that the sliding door is closed.

4. The vehicular illumination mechanism according to claim 1 , wherein the illuminating lamp includes a plurality of lamps spaced apart to each other on the upper face portion of the loading and unloading mechanism of the vehicle.
