Abstract

A light emitting display device, which is applied to a vehicle provided with an airbag device having an airbag accommodated in a folded state and an airbag cover with a shape of covering a vehicle interior of the airbag, the light emitting display device includes: a light emitting display part provided to the airbag cover, the light emitting display part configured to emit light using supplied power; a power feeding device including a power reception coil and a power transmission coil, the power feeding device configured to supply power to the light emitting display part in a non-contact manner, wherein: the power reception coil is provided to the airbag cover in a state of being integrated with the light emitting display part; and the power transmission coil is arranged at a position out of a range, in which the airbag is deployed, when the airbag device is operated.

First claim

What is claimed is:

1. A light emitting display device, which is applied to a vehicle provided with an airbag device having an airbag accommodated in a folded state and an airbag cover with a shape of covering a vehicle interior of the airbag, the light emitting display device comprising:
a light emitting display part provided to the airbag cover, the light emitting display part configured to emit light using supplied power; and
a power feeding device including a power reception coil and a power transmission coil, the power feeding device configured to supply power to the light emitting display part in a non-contact manner, wherein:
the power reception coil is provided to the airbag cover in a state of being integrated with the light emitting display part;
the power transmission coil is arranged at a position out of a range, in which the airbag is deployed, when the airbag device is operated; and
the power transmission coil is provided to the airbag cover.

2. The light emitting display device according to claim 1 , wherein:
the airbag cover has a cylindrical peripheral wall, which is provided to protrude at a surface of a side of the airbag to surround a periphery of the airbag;
the power transmission coil is provided to extend outside the peripheral wall; and
the power reception coil and the light emitting display part are provided inside the peripheral wall.

3. The light emitting display device according to claim 1 , wherein
the power transmission coil is arranged to extend along an outer edge of the airbag cover.

4. A light emitting display device, which is applied to a vehicle provided with an airbag device having an airbag accommodated in a folded state and an airbag cover with a shape of covering a vehicle interior of the airbag, the light emitting display device comprising:
a light emitting display part provided to the airbag cover, the light emitting display part configured to emit light using supplied power; and
a power feeding device including a power reception coil and a power transmission coil, the power feeding device configured to supply power to the light emitting display part in a non-contact manner, wherein:
the power reception coil is provided to the airbag cover in a state of being integrated with the light emitting display part;
the power transmission coil is arranged at a position out of a range, in which the airbag is deployed, when the airbag device is operated; and
the light emitting display device further comprises:
a power change unit configured to change a supply mode of power to the power transmission coil; and
a light emitting change unit configured to change a light emitting mode of the light emitting display part according to power received by the power reception coil.

5. A light emitting display device, which is applied to a vehicle provided with an airbag device having an airbag accommodated in a folded state and an airbag cover with a shape of covering a vehicle interior of the airbag, the light emitting display device comprising:
a light emitting display part provided to the airbag cover, the light emitting display part configured to emit light using supplied power; and
a power feeding device including a power reception coil and a power transmission coil, the power feeding device configured to supply power to the light emitting display part in a non-contact manner, wherein:
the power reception coil is provided to the airbag cover in a state of being integrated with the light emitting display part;
the power transmission coil is arranged at a position out of a range, in which the airbag is deployed, when the airbag device is operated; and
the light emitting display part includes an emblem and a light emitting diode for allowing the emblem to emit light.
