Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure of an air bag device mounted on a passenger side of an automobile, and more particularly to a mounting structure of an air bag module having a lid fitted into an opening of an instrument panel to a vehicle body.

[0002]

[Prior Art]

 First, the airbag module will be described. This type of air bag device consists of an inflatable air bag, an air bag unit consisting of an inflating gas generator and a gas generating agent ignition means, a collision sensor, and a power supply such as a condenser and an operating circuit. Is the one in which these are integrated. Next, the attachment of the lid will be described. The airbag device for the passenger seat is arranged on the back surface of the instrument panel, and the instrument panel is provided with an opening for inflating the airbag and a lid (airbag door) fitted into the opening. This lid may be attached to the instrument panel or the air bag module, but from the viewpoint of workability of attaching / detaching the lid, work space restriction, and securing the attachment strength when the air bag swells, the air bag is used. Often mounted on a module.

Next, a specific example of a conventional air bag module mounting structure will be described with reference to FIG. FIG. 4 is a sectional view showing a conventional air bag module mounting structure. In FIG. 4, the airbag module 2 has a lid body 3, a clip 18, and a mounting portion 6, is fitted into the opening 14 of the instrument panel 4, and is provided to the vehicle body member 8 via the adjustment bracket 5. It is attached to the member bracket 7. A step 15 is provided in the cross section of the opening 14, and the lid 3 is fitted into the stepped opening surface. The clip 18 has a spring shape and holds the position of the airbag module 2 with respect to the opening 14. When mounting the air bag module 2, first insert the air bag module 2 into the opening 14 of the instrument panel 4, and then use the clip 18 or the like to align the gap 16 between the instrument panel 4 and the lid 3. It is done and adjusted to the desired state. Further, two of the four sides of the flange 3a of the lid 3 have a protrusion 3b formed with high precision, and the protrusion 3b abuts the step 15 so that the surface step 17 is predetermined. It is temporarily fixed while maintaining accuracy. Following this matching work, the following mounting work is performed.

In this mounting work, it is required that the gap 16 and the surface step 17 adjusted in the matching work are not deviated. However, at the time of attachment to the vehicle body member 8, the gap 16 and the surface step 17 are not only accurate in the instrument panel 4 and the lid body 3, but also in the air bag module 2 and the lid body 3. It is affected by the mounting accuracy, the mounting accuracy of the air bag module 2 and the vehicle body member 8, and the accuracy of each of the air bag module 2 and the vehicle body member 8 and the stacking of many accuracy levels. Therefore, it is difficult to suppress the positional relationship between the airbag module 2 and the vehicle body member 8 in terms of design. Therefore, the position of the airbag module 2 can be adjusted by interposing an adjustment bracket 5 between the airbag module 2 and the member bracket 7. That is, the adjustment bracket 5 is a V-shaped plate having a height adjusting portion 5a and a horizontal position adjusting portion 5b. The height adjusting portion 5a is provided with a mounting hole 9 and a bolt 12 is used to attach the air bag module. It is fastened to the mounting part 6. The mounting hole 9 is a long hole, and its position can be adjusted in the height direction. Further, a mounting hole 10 is provided in the horizontal position adjusting portion 5b and is fastened to the member bracket 7 with a bolt 13. The mounting hole 10 is a stupid hole with respect to the diameter of the bolt 13, The position can be adjusted in any direction. The member bracket 7 is a plate-shaped member and is fixed to the vehicle body member 8 by welding 11. With these structures, the adjustment bracket 5 adjusts the height and horizontal position to absorb unmatches due to variations in the mounting hole position, mounting surface angle, etc. of the airbag module 2 and the member bracket 7 in the above-described state. The air bag module 2 and the member bracket 7 are fixed in a state where the instrument panel 4 and the lid 3 are kept in good alignment.

[0005]

[Problems to be solved by the device]

 However, in the mounting structure using the adjustment bracket 5 shown in FIG. 4, there are cases where the good alignment between the instrument panel 4 and the lid 3 cannot be maintained. Such a case will be described with reference to FIG. FIG. 5 shows the case where the angles of the airbag module 2 and the member bracket 7 do not match. The angle also varies due to the accuracy of parts and mounting, and in such a case, the position cannot be adjusted even by adjusting the position in the horizontal direction and the height direction as described above. If this is forcibly fastened, the lid 3 tilts as shown by the chain double-dashed line, and the alignment between the instrument panel 4 and the lid 3 becomes incorrect. That is, there is a problem that the conventional mounting structure shown in FIG. 4 cannot cope with the angle variation.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to attach an instrument panel and a lid so that the air bag module is not misaligned when the air bag module is attached. To provide the structure.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the mounting structure for an airbag module according to the present invention has an opening provided in an instrument panel, and a lid body that fits in the opening and forms a substantially flush surface with the instrument panel. In the mounting structure of the air bag module, the air bag module is arranged on the rear surface of the instrument panel, and the air bag module is attached to the member bracket provided on the vehicle body member through the adjustment bracket. The feature is that the adjustment bracket has a variable angle.

[0008]

[Action]

 The angle variable member bracket or the adjustment bracket absorbs the variation in angle due to the mounting accuracy of the air bag module and the lid, the mounting accuracy of the air bag module and the vehicle body member, or the accuracy of the individual products.

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a mounting structure of an air bag module of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. 3 is a sectional view showing another embodiment. The same components as those described with reference to FIG. 4 are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 1, the member bracket 27 has a plate shape and is fixed to the collar 28 by welding 11. The collar 28 is rotatably fitted to the vehicle body member 8 with a clearance 37 of about 0.5 mm so that the angle between the vehicle body member 8 and the member bracket 27 can be adjusted. The angle can be fixed by tightening the insect screw 30. Here, as shown in FIG. 2, a groove 38 may be provided in a portion with which the insect screw 30 abuts, whereby the axial position of the member bracket 27 can be stabilized. As a result, even if the angle between the air bag module 2 and the member bracket 7 does not match as shown in FIG. 5, adjustment is possible.

FIG. 3 shows that the adjustment bracket 25 is made rotatable instead of the member bracket 27 being rotatable in FIG. That is, in FIG. 3, the adjusting bracket 25 is provided with a hinge joint 31 between the plate-shaped height adjusting portion 25a and the horizontal position adjusting portion 25b so that the angles of both can be adjusted. Then, a screw 26 is provided on the hinge joint 31, and the angle can be fixed by tightening the screw 26. As a result, the same operational effect as that of the above-described FIG. 1 is achieved.
