Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for assembling equipment within an instrument panel of a motor vehicle, and particularly to a method for assembling an airbag within an instrument panel.

[Prior art]

Traditionally, an airbag has been installed in the instrument panel on the passenger side of a car to inflate in an emergency to ensure the safety of the passenger. It is common practice to install the airbag by fixing it to the steering support member (
(For example, see Japanese Utility Model Application Publication No. 1-81154).

[Problem to be solved by the invention]

However, in the instrument panel on the passenger side of a normal car, a Tara unit for air conditioning is installed below the front of the steering support member to which the airbag is fixed, and below the back of the steering support member. Because air conditioning ducts are installed that extend across the width of the vehicle, tools cannot be inserted from below during airbag maintenance and inspection, making it difficult to assemble the airbags. There was a problem.

In order to solve this problem, it has been proposed to reduce the diameter of the air conditioning duct, but when the diameter of the air conditioning duct is reduced, the cross-sectional area of the ventilation passage becomes smaller, resulting in a reduction in ventilation capacity.

An object of the present invention is to provide an assembly method in an automobile instrument panel that solves the problem described in item 1 and allows easy servicing of airbags while ensuring a sufficient cross-sectional area of the air conditioning duct. The goal is to provide the following.

[Means to solve the problem]

” - In order to achieve the above object, the method of assembling in an automobile instrument panel of the present invention is such that an air hang unit on the passenger seat side is fastened and fixed from below in the automobile instrument panel I, and In vehicles that are designed to allow maintenance and inspection from below, move the central axis of the air conditioning duct located below the fastening part of the air hug unit I and extending in the width direction of the vehicle to the rear. As a result, the space created in front of the air conditioning duct is used to perform work by inserting tools from below.

[Function] In the method of assembling the vehicle instrument panel of the present invention configured as described above, the air conditioning is A space is formed in front of the duct 1-, and tools are inserted through the created space to perform service work.

〔Example] Embodiments of the present invention will be described based on the drawings.

An embodiment to which the present invention is applied will be described with reference to FIGS. 1 to 3. An airbag unit 3 having a lid 2 that can be opened and closed inside the instrument panel 1 on the passenger seat side.
is installed.

The air hang unit 3 has a flange 31 at the bottom, a gas generator 32 and a balloon 33 are housed inside, and is attached to a bracket 41 across a steering support member 4 extending in the width direction of the vehicle body. The airbag unit 3 is fixed to the steering support member 4 by fastening and fixing the take-off flange 31 of the airbag unit 3 from below with the bolts 7.7 using the tool 6.

At the lower rear of the steering support member 4 and below the air hang unit 3, an air conditioning duct 1-5 extends in the width direction of the vehicle body. For example, one end of the air conditioning duct 5 is communicated with a side vent via a connecting pipe 50. , the other end is connected to the main duct of the air conditioner via a connecting pipe 51.

A cooler unit 8 is installed in the front lower part of the steering support member 4 facing the dash panel 9, and is installed near the cowl box 10 in front of the instrument panel 1 and facing the interior surface of the vehicle at the bottom of the front window 11. A differential duct 52 that opens is installed.

The air conditioning duct 5 has a connecting portion 5a to a connecting pipe 50.51.
The main parts except for the connecting part 5 are formed in a flat cross section A.
Since the center of the air conditioning duct 5 is shifted from the center of the air conditioning duct 5 in the long direction of the flat cross section, when the air conditioning duct 5 is rotated around the central axis of the connecting pipe 50, 51, the air conditioning The duct 5 rotates around the center of the connecting portion 5a, which is a position shifted in the long sleeve direction of the flat cross section A, and as shown in FIG. 2, the long sleeve direction of the flat cross section A is approximately -・When it is at the position of the solid line 5, which corresponds to the solid line 5, the vertical dimension is small, and the dedicated space in the vertical direction is small. In this case, the exclusive space in the front and back direction is small, and a space can be secured in which the tool 6 can be easily inserted from below.

Note that the main part of the air conditioning duct l-5 may be formed to have a circular cross section with a larger diameter than the connecting part 5a, and the central axis of the main part of the air conditioning duct 5 and the central axis of the connecting part 5a may be offset, By rotating the air conditioning duct 5 around the central axis of the connecting portion 5a, the same effect as that of the flat cross section can be achieved.

・Also, to explain another embodiment in FIG. 4, the air conditioning duct 500 has a normal circular cross section, and the connecting portion 501 to the connecting pipe 50 is formed by an expandable bellows tube, and the center of the air conditioning duct 500 is The shaft can be shifted from the central axis of the connecting pipe 50, and a space for inserting and working the tool 6 from below can be secured.

In addition, if the connecting part 501 with one connecting pipe 50 is also made of a bellows tube, the moving distance of the air conditioning duct 500 can be increased, and the work space can be saved. It is possible to secure a large amount of

In the above-described configuration, the method of assembling the vehicle's instrument panel is such that the airbag unit 3 on the passenger seat side is fastened and fixed in the instrument panel 1 from below, and services such as maintenance and inspection are carried out from below. In those installed as possible, the airbag unit 3
By moving the central axis of the air conditioning duct 5, which is located below the fastening part and extends in the width direction of the vehicle body, to the rear, the tool 6 is inserted from below using the space created in front of the air conditioning duct 5. The staff will perform maintenance and inspection work on the airbag unit 1-3.

According to the above method of assembling inside an automobile instrument panel, it is possible to secure a sufficient cross-sectional area of the ventilation path of the air conditioning duct 5, and it is also possible to easily perform service work on the air bag unit 3. .

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

The central axis of the air conditioning duct located below the fastening part of the airbag unit that is fastened from below is moved rearward,
By creating a space in front of the air conditioning duct and inserting tools through the created space to perform service work, it is possible to secure a sufficient cross-sectional area of the ventilation path of the air conditioning duct, and to perform service work on the air hang unit. can be easily carried out.
