Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle seat having mood lighting and metal molding,

The present invention relates to a vehicle seat provided with mood lighting and metal molding. More specifically, the present invention relates to a vehicle seat which can be combined with a mood lighting member and a metal molding to be introduced into a seat to realize a pleasing appearance.

BACKGROUND ART [0002] There is known a technique of introducing mood lighting to enhance the interior and interior of a vehicle such as a passenger car and to introduce a display function. Such a mood lighting member is used as a lighting strip in a dashboard, a roof liner between the grip handles, and the like, and is used to create a pleasant aesthetic feeling. In particular, interior lighting is becoming increasingly important in advanced class vehicles.

In addition, such an interior lighting technology plays an important role in easily identifying buttons and the like, and in creating a more pleasant environment and a high sensitivity effect inside the vehicle.

In recent years, there has been known a technique for implementing a more refined interior by applying mood lighting in a vehicle using modern lighting technology, for example, an LED or an optical fiber, and further, a technique of adding mood lighting to a vehicle seat is also known.

In this regard, U.S. Patent No. 6,854,869 relates to an optical assembly for interior or mood lighting for imparting aesthetics to a vehicle seat, the lighting assembly comprising: (i) light emitted from an LED, which is a light source, (Ii) is configured to reflect light backwards by a reflector attached to the distal end of the optical fiber bundle. That is, the light emitted from a single LED source is illuminated through the bundle of optical fibers attached to the covering of the seat.

Meanwhile, vehicle consumers are known to prefer an indirect interior lighting scheme for a more distinctive decorative effect.

As a technique for applying such indirect interior lighting technology to a sheet, US Re-registered Patent No. 42340 discloses a technique for forming light emitted from a luminescent panel in fabric covering so as to pass through a fabric cover layer.

Japanese Patent Application Laid-Open No. 2001-186965 proposes a sheet in which LEDs are linearly arranged on the lower side of the cover to provide a continuous luminous effect.

In addition, U.S. Patent No. 8,162,519 discloses a method of using a semi-transparent fabric cover material that is a material that can completely hide the lighting arrangement from the field of view but under light illumination, (i) the LED is not exposed on the interior surface , (ii) the light emitted from the LED is passed through the semi-transparent fabric cover material layer to the interior of the vehicle, and (iii) the light emitted from the light transmitting member passes through the semi-transparent fabric cover material layer Which is an indirect lighting method.

However, most of the above-mentioned prior arts focus on applying only the mood lighting technique to the interior member of the vehicle, for example, the seat, and thus there is a limit to create a combined aesthetic feeling.

Accordingly, it would be more advantageous if new feelings and aesthetics could be realized by combining the additional aesthetic improvement elements as well as the mood lighting function applied to the conventional vehicle seat.

In the present invention, it is desired to provide a vehicle seat with high sensitivity that can provide a smooth and pleasant interior environment by combining a lighting string member and a metallic luster molding strap so as to overcome the limitations of the related art.

According to one embodiment of the present invention,

A sheet cover layer sequentially arranged from the front side of the sheet; A molding portion of metallic luster formed along at least one region of the rim of the sheet and having a strap shape; And a seat back panel;

According to another embodiment, the molding portion of the metallic luster can be disposed between the cover layer and the sheet back panel along the side edge of the sheet.

In an exemplary embodiment, the light source may be an LED element.

According to the embodiment of the present invention, the lighting string member is disposed by utilizing the space formed by the combination of the metallic luster molding part and the seat back panel disposed along at least one of the rims of the vehicle seat, It is possible to provide an improved aesthetic feeling as compared with the conventional art that simply provides a decoration effect by the lighting string member alone.

Particularly, the light emitting source is not directly exposed to the naked eye, but is emitted through the gap between the molding part of the metallic luster and the seat back panel, thereby realizing a highly sensitive visual effect. Moreover, the ability to combine light sources of varying colors with luxurious metal luster has the advantage of providing a softer, higher level of aesthetics.

Therefore, wide commercialization is expected in the future.
