DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instrument panel structure provided with a partition panel for separating a storage portion of a glove box from a storage portion of an airbag.

[0002]

2. Description of the Related Art As shown in FIG. 11, a glove box 101 is usually provided on a passenger seat side of an instrument panel 100 disposed in a front part of a vehicle interior of a four-wheeled vehicle. An airbag 102 for a passenger seat is mounted on an upper portion of 101. Further, the instrument panel 100 is provided with a partition panel 103 for partitioning between the storage section of the glove box 101 and the storage section of the airbag 102. After the wiring harness 104 is connected, it is assembled to the instrument panel 100.

Conventionally, the wiring between the harness on the vehicle body side and the harness of the airbag is performed by the following two methods. A separate partition panel is provided between the glove box storage section and the airbag storage section of the instrument panel, and after connecting the vehicle body side harness and the airbag harness, the partition panel is assembled. A partition panel having a maintenance hole provided in the instrument panel is assembled in advance, and in a vehicle manufacturing line, the harness on the vehicle body side and the harness of the airbag are connected, and then the maintenance hole is separately covered.

[0004]

The above conventional methods have the following problems. Since the instrument panel and the partition wall panel must be assembled in the process of the vehicle manufacturing line, the number of assembly steps in the line is increased. Since a separate lid is required for the maintenance hole, the number of parts increases, and the assembly of the lid requires man-hours on the vehicle production line.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an instrument capable of performing a wiring work of a harness in a state where a partition wall panel for separating a storage portion of a glove box and a storage portion of an airbag is attached. It is intended to provide a panel structure.

[0006]

According to the present invention, there is provided an instrument panel structure having an openable and closable glove box on an instrument panel main body and an airbag above the glove box. The instrument panel main body is provided with a partition panel for separating the storage section of the glove box and the storage section of the airbag, and the maintenance panel is closed in the partition panel so that the maintenance hole can be opened and closed. A lid is provided, and one end of the lid is connected to the partition panel. In the present invention, a hole for passing a harness is provided in a partition panel provided between a glove box storage part and an airbag storage part (upper part of a glove box) of an instrument panel. The structure has a lid integrated with the partition wall panel.
