BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of an air bag grid.

[0002]

2. Description of the Related Art Some automobiles include, for example, Japanese Unexamined Patent Publication No.
As disclosed in Japanese Patent Publication No. 98547, an airbag unit is known in which an airbag unit is incorporated at a position corresponding to the front of a front passenger seat on an instrument panel in order to protect passengers in the front of a front passenger.

This will be described in detail with reference to FIGS. 3 and 4. Reference numeral 1 denotes an instrument panel, which is located at a position corresponding to the front of the front passenger seat and is turned around from the upper surface of the instrument panel 1 into the lower cover portion 2 and has an opening. A portion 3 is formed, and an airbag device 4 is disposed substantially in the upper half of the opening 3.

[0005] Reference numeral 5 denotes an air bag grid which is mounted on the upper half of the opening 3 so as to cover the air bag device 4, and a pad material 7 is integrally molded on a surface of a substrate 6 made of a flexible plate material such as an aluminum thin plate. The upper edge flange 6a of the substrate 6 is fixed to the upper edge of the opening 3 with bolts and nuts 8, and when the airbag device 4 is operated, the airbag lid 4 is deployed by the deployment force of the airbag body 4a. Reference numeral 5 allows the upper edge flange 6a to open upward, that is, open upward, using the bolt / nut 8 fixing point as a hinge point. Further, a socket portion 9 is provided on the back surface of the lower end portion on both sides of the airbag grid 5, and this socket portion 9 is attached to the airbag device 4.
Alternatively, the lower end of the airbag lid 5 is held so as not to move by fitting to the clip 10 provided on the side edge of the opening 3.

[0005] A glove box lid 13 is provided at a lower half of the opening 3 with a hinge point 12 at a lower portion so as to open and move downward, that is, open downward. The upper end 13a of the glove box lid 13 is arranged in alignment so as to obtain a continuous surface. In FIG. 4, reference numeral 14 denotes a box body of the glove box 14A.

[0006]

When the glove box lid 13 is opened, the lower end 5a of the airbag lid 5 is exposed in the opening 3, so that a finger is caught on the lower end 5a of the airbag lid 5 and the airbag lid 5 is closed. May be opened upward. Once the airbag lid 5 is opened, the upper edge flange 6a of the substrate 6 serving as a hinge point is deformed, and even if the airbag lid 5 is reclosed again, the integrity of the glove box lid 13 deteriorates and the appearance is impaired. I will.

Therefore, the present invention can reliably prevent the air bag grid from opening up in a normal state, and when the air bag device is activated, the air bag main body uses the unfolding force of the air bag body.
An object of the present invention is to provide an airbag lid mounting portion structure that can easily open the airbag lid.

[0008]

Means for Solving the Problems An upper part of an opening formed in an instrument panel is covered with an airbag device disposed in the upper part of the opening, and a hinge point is provided at an upper part. Attach the air bag lid that opens up,
In a structure in which a glove box lid which opens downward with a hinge point at a lower portion thereof is attached to a substantially lower half portion of the opening, and a lower end of the airbag lid and an upper end of the glove box lid are arranged in alignment. A lock portion that locks to the lower end of the air bag grid to fix the lower end of the air bag grid near the lower end of the air bag grid in the opening, and that receives the deployment force of the air bag main body when the air bag device is activated. A lid lock device having a pressure receiving portion for unlocking the lock portion is provided.

[0009]

When the airbag device is operated and the airbag body is deployed, the pressure receiving portion of the lid lock device partially receives the airbag body and senses the deployment force, thereby immediately unlocking the lock portion. As a result, the airbag lid is quickly opened centering on the upper hinge point by the deployment force of the airbag body, allowing the airbag body to be deployed into the vehicle interior.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, in which the same reference numerals are assigned to the same parts as in the above-mentioned conventional construction.

In FIGS. 1 to 3, an airbag device 4 is disposed in a substantially upper half of an opening 3 formed by wrapping around the lower cover 2 from the upper surface of the instrument panel 1. Is covered with the airbag device 4 and fixed by bolts and nuts 8 on the upper edge flange 6a of the substrate 6 made of a flexible plate material such as an aluminum thin plate. At the point where the airbag lid 5 is mounted so that the airbag lid 5 is opened upward with the bolt / nut 8 fixing portion of the upper edge flange 6a as a hinge point due to the deployment force of the airbag main body 4a, at the substantially lower half of the opening 3 Is equipped with a glove box lid 13 that opens downward with a hinge point 12 at the bottom, and aligns the lower end 5a of the airbag lid 5 with the upper end 13a of the glove box lid 13. That is arranged Te, the basic structure and the like are the same as the conventional.

An engaging hook 6b formed on the substrate 6 is provided near the lower end 5a of the airbag lid 5 in the opening 3 and below the lower end 5a of the airbag lid 5.
And a pressure receiving portion 18 that unlocks the lock portion 17 by receiving the deployment force of the airbag body 4a when the airbag device 4 is activated. The provided lid lock device 15 is provided.

The locking hook 6b is formed at the lower end of the substrate 6 of the airbag lid 5 so as to be bent in a substantially U-shaped side surface and to extend outward. Reference numeral 16 denotes a lock lever, which is disposed on a side edge of the opening 3 and functions as a lid lock device 15 that engages with the locking hook 6b. More specifically, the lock lever 16 is formed in a substantially J-shaped side surface, and a substantially central portion of a lower curved portion is rotatably mounted on a side edge of the opening 3 by a pin 19, and is provided at one end. Is formed with a hook portion 17a serving as a lock portion 17 which is engaged with the locking hook 6b from below, and has an airbag body 4 at the other end.
A pressure-receiving portion 18 is formed to receive the lower portion when a is deployed.

According to the structure of the above-described embodiment, with the glove box lid 13 opened, a finger is placed on the lower end of the air bag grid 5 and the air bag grid is lifted obliquely upward as shown by an arrow a in FIG. Even if the user tries to open the lock lever 5, the locking hook 6 b is
a, and the lock lever 16 keeps the airbag lid 5 fixed against the opening power, that is,
Maintain the locked state.

Next, at the time of a vehicle collision or the like, the airbag device 4
When the airbag body 4a is deployed by operating the airbag body 9, the airbag body 9 comes into contact with the pressure receiving portion 18 of the lock lever 16 to push the pressure receiving portion 18. As a result, the lock lever 16
Is rotated clockwise in FIG. 1 around the pin 19, and the hook portion 17a is disengaged from the locking hook 6b.
Unlock the bottom edge. Therefore, the air bag grid 5
Is quickly opened upward by the deployment force of the airbag body 4a, allowing the deployment of the airbag body 4a into the vehicle interior.

In the above embodiment, the lid lock device 1
Although the lever type is disclosed as a cost-effective lever 5, an electromagnetic actuator that unlocks by operating a pressure-sensitive switch can also be used. In this case, the pressure-sensitive switch is connected to the airbag body. What is necessary is just to arrange in a deployment area and to be a pressure receiving part.

[0017]

As described above, according to the present invention, the lid lock device normally locks the lower end portion of the air bag grid in a normal state, and can prevent the air bag grid from opening due to mischief. On the other hand, when the airbag device is activated, the airbag body receives the deployment force of the airbag body and senses this, and the lock portion can be immediately unlocked, so that the airbag grid is quickly opened up by the deployment force of the airbag body. Therefore, the quality and reliability can be further improved.
