Description

  The present invention relates to a design lighting structure in a vehicle compartment. More specifically, the present invention relates to a lighting structure for a design in a vehicle interior that is incorporated in an interior configuration of the vehicle interior.

  As this kind of illumination structure, an illumination structure incorporated in a vehicle seat is described in Patent Document 1 below. The sheet described in the following Patent Document 1 is such that a bead formed by covering an electroluminescent fiber with a transparent resin cover is sewn on a stitched portion of the sheet cover, and causes the bead to emit light. Therefore, a decorative effect is expected.

JP 2001-186965 A

  However, in the above conventional sheet, the electroluminescent fiber is incorporated as a part of the outer surface of the sheet skin constituting the design surface of the sheet as a bead, and is exposed on the design surface of the sheet. For this reason, a decorative effect is expected when the ball edge is made to emit light, but when the ball edge is not made to emit light, the appearance of the sheet tends to be impaired.

  Therefore, the problem to be solved by the present invention is to provide an illumination structure for a design in a vehicle compartment that does not impair the appearance even when light is not emitted.

  The present invention is an illumination structure for a design in a vehicle interior that is incorporated in an interior configuration of a vehicle interior, and includes a long light guide bar that emits light to an internal position from a design surface of the interior configuration of the vehicle interior. The light guide bar is provided with a light source at an end thereof, and is configured to emit light by scattering light emitted from the light source in a circumferential direction while transmitting through the inside of the long bar. In the design surface, a light transmission part capable of transmitting the light emitted from the light guide rod is formed.

  The interior configuration of the vehicle interior in the present invention is a member constituting the interior of the vehicle interior and the vehicle interior surface, and examples thereof include a seat and a trim. According to the present invention, the light guide bar is disposed at an internal position from the design surface of the interior configuration in the vehicle compartment. The design surface of the interior configuration in the vehicle interior is an outer surface visually recognized in the normal installation structure of the interior configuration in the vehicle interior. That is, since the light guide bar is disposed at an internal position from the design surface and is not exposed, the appearance of the interior configuration in the vehicle compartment when the light guide bar is not emitting light is not impaired. However, since the light emitted from the light guide bar passes through the light transmitting part formed on the design surface of the interior structure of the vehicle interior and leaks into the vehicle interior, the light emitted from the light guide bar is emitted by the light. Design expression is possible. Therefore, according to the illumination structure for design in the vehicle interior of the present invention, it is possible to emit light from the design surface of the interior configuration in the vehicle interior, but the appearance is not impaired even when the light is not emitted.

  In the illumination structure for a design of a vehicle according to the present invention, it is desirable that the light guide rod is buried in a pad material inside the skin of the interior configuration of the vehicle interior. In this case, since the light guide bar does not protrude from the design surface of the interior configuration in the vehicle compartment, it is difficult to break. Even if the interior structure of the vehicle interior is a vehicle seat and the occupant is seated in the illumination structure for design for a vehicle, the light guide rod does not protrude, so there is no risk of lowering the ride comfort.

  In the illumination structure for a design in a vehicle compartment according to the present invention, a skin cover is disposed on a design surface of the interior configuration in the vehicle compartment, and the light transmission portion may be a seam of a skin piece constituting the skin cover. desirable. For example, the interior configuration of the vehicle interior is a vehicle seat installed in the vehicle interior, and a skin cover is disposed as a design surface on the vehicle seat, and the light transmission portion configures the skin cover. It can be a seam of skin pieces. Here, it is preferable that the seam of the skin piece that is the light transmitting portion is a seam of the skin piece connected by stitching (seam of the skin). Since the seam of such a skin piece is generally formed along the contour of the vehicle seat, for example, the contour of the seating surface can be illuminated by emitting light from the seam. Moreover, the joint of the skin piece which is a light transmissive part is good also as a slide fastener which connects a skin piece.

  In the design lighting structure in the vehicle compartment according to the present invention, it is also preferable that a gap between a plurality of members constituting the design surface of the interior configuration in the vehicle compartment is the light transmission portion. For example, the interior configuration of the vehicle interior is a vehicle seat installed in the vehicle interior, the vehicle seat has a shield member disposed on the outer periphery of a seat cushion serving as a seat surface, and the light transmission portion is It can be set as a gap between the seat cushion and the shield member. The interior structure of the vehicle interior is a vehicle seat installed in the vehicle interior, and the light transmission portion is a gap between a seat cushion serving as a seat surface of the vehicle seat and a seat back serving as a backrest. You can also.

  The illumination structure for a design in a vehicle compartment according to the present invention is a skin composed of a light-transmitting skin material capable of transmitting at least part of the light emitted from the light guide rod on the design surface of the interior configuration in the vehicle compartment. A cover may be provided, and the light transmission part may be formed of a light-transmitting skin material of the skin cover.

  According to the design illumination structure in the vehicle interior of the present invention, it is possible to emit light from the design surface of the interior configuration in the vehicle interior, but the appearance is not impaired even when the light is not emitted.
