Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an airbag door structure for facilitating bulging of an airbag incorporated in a vehicle instrument or maintenance and inspection of the airbag.

[0002]

[Prior Art]

 A conventional mounting mode of an air bag device provided to enhance the safety of passengers in a vehicle collision is, for example, as shown in FIG. That is, in order to reduce the injuries to the driver, for example, in the event of a collision of a vehicle, or to prevent a fatal accident, the impact force is detected and immediately inflated in front of the driver's seat or the passenger's seat when the vehicle crashes into the vehicle and the driver is injured. Airbag devices for protecting persons or passengers from impacts are known as motor vehicle safety equipment.

The function of the airbag device is to protect the body by absorbing the inertial force in the direction of the windshield of the driver or the assistant, which is generated when the vehicle collides with the vehicle. Depending on the strength of the force, the support stiffness of the airbag system must be strong in order to receive the driver's inertial force generated during the collision.

Therefore, as shown in FIG. 1, a conventional air bag device includes a steering member 2 made of an iron pipe, which is parallel to the width direction of a vehicle, inside an instrument 1 installed in front of a driver's seat. The steering member 2 is firmly fixed so as to be integrated with the frame, and the airbag 3 is supported by the steering member 2 so that the inertial force of the human body at the time of a vehicle collision is swelled through the airbag 3 and the steering member is supported. It was something to accept.

Further, in order to assist the swelling of the airbag at the time of a vehicle collision, the instrument 1 is provided with an airbag window 4, and the airbag window 4 can be opened and closed. An airbag door 5 that can be installed is provided so as to be openable and closable. That is, the airbag door 5 is composed of a base plate 5a and an instrument pad 5b provided on the surface of the base plate 5a. One end of the airbag door 5 is attached to the second base plate 6 fixed to the front inside of the instrument by a mounting screw 7. It is fixed by. The other end of the airbag door 5 is provided with a protruding portion 8 protruding inside the instrument, and the protruding portion 8 is fixed inside the instrument 1 via a stay 9 and has a U-shaped receiving member 10. Is removably fitted to. When the vehicle collides with the airbag and the airbag inflates, the airbag door 5 is pushed by the inflated airbag, whereby the protrusion 8 and the receiving portion 10 are disengaged, and the airbag is removed. The base plate is bent around the portion A of the door 5 and the airbag door 5 is expanded.

[0006]

[Problems to be solved by the device]

 However, in such a conventional air bag door structure, a mechanism for opening the window 4 only when the air bag is operated is used, for example, when the air bag device is inspected for malfunction or after the air bag is operated. Since it is impossible to open the air bag door 5 during the device replacement work, the entire instrument 1 must be removed during the above-mentioned malfunction inspection and replacement work, which is extremely inferior in workability. there were.

[0007]

[Means for Solving the Problems]

 The present invention has been made in view of such a conventional problem, and has a structure in which the air bag door can be repeatedly opened and closed at appropriate times, so that maintenance and replacement of the air bag can be performed from the air bag window. (EN) Provided is an airbag door capable of performing the above work so as to enhance the workability of the above work.

[0008]

【Example】

 The present invention will be described in detail below based on the embodiment shown in FIGS. 2 and 3. The same parts as the structure of the present embodiment and the structure described in the conventional example are denoted by the same reference numerals used in the conventional example. The description of the same structural parts will be omitted.

Reference numeral 15 is an air bag door of this embodiment, and this door 15 is composed of a base plate 15a and a pad 15b attached on the base plate 15a. A door support 16 is fixed to the inside of the instrument 1. The door 15 is attached to the end of the door support on the side of the window 4 via a hinge 17 so as to be openable and closable. A concave stopper 18 for restricting the opening degree of the door 15 is formed on the hinge mounting portion of the door support 16. Reference numeral 19 denotes a mounting screw for the hinge 17, and 20 denotes a glove box.

As is clear from the above description, since the door 15 attached to the airbag window 4 that does not prevent the bulging of the airbag 3 is attached by the hinge 17 so as to be openable and closable, It is possible to repeatedly open and close the door 15. Therefore, by opening the door 15, the maintenance and inspection of the air bag device installed in the instrument, and the replacement work with a new air bag can be easily performed from the air bag window 4.

Further, in the above-described embodiment, since the stopper 18 for restricting the opening degree of the airbag door 15 is provided, a rapid impact that opens the airbag door 15 when the airbag 3 swells is generated. Even if it acts on the airbag door 15, the airbag door 15 does not collide with the windshield 11, and therefore the windshield 11 is not damaged by the operation of the airbag device.

[0012]

[Effect of the device]

 As described above, the present invention is the airbag door in which the door 15 that can be opened and closed by the hinge means 17 is provided in the airbag inflation window 4 provided on the upper surface of the instrument of the automobile. Since the door 15 can be repeatedly opened and closed at appropriate times, the opening of the door 15 enables maintenance and inspection of the airbag device installed in the instrument, and replacement work with a new airbag. The effect that it can be easily performed from the window 4 is obtained.
