Connecting device for airbag module of passenger}

The present invention relates to a passenger airbag connection device, which allows a more detailed hinge panel and support panel to be integrally formed so that the rigidity and smooth deployment of the hinge panel can be made when the airbag is deployed. It is about.

Vehicle safety devices include active safety devices (brake, ABS, TCS, Navigation) to prevent accidents and passive belts (safty belt, airbag pretentioner) to protect passengers' lives or life in the event of an accident. Are classified.

The airbags of these safety devices are devices that protect the occupants by inflating the bags before the second collision in the event of a collision, and are used to prevent facial injury by being mounted on the driver's seat and the passenger seat.

Airbags include meteorites equipped with airbag modules mounted on steering wheels, collision sensors attached to the vehicle body, and turning lights that combine these with diagnostic circuits. It is equipped with a conscious system and a small bag system with a capacity of about 45L, which is called the Euroback and is equipped with a three-point belt.

In addition, there are several types of passenger seats, depending on where the passenger seat airbags are placed on the instrument panel. It is a downward installation type housed in the lower part of the instrument panel, an upper installation type in which the unit is mounted almost horizontally on the upper part of the instrument panel, and an upper installation type in which the unit is installed on the upper surface of the instrument panel and the bag is deployed upwardly inclined.

These airbags can be covered by the module cover so as not to be exposed to the outside from the inside of the vehicle, and the module cover not only stores the cushion in a certain form but also contributes to the appearance of the vehicle.

In addition, if you look at the basic conditions of the airbag module, not only the bag should not be scattered during inflation, but also should be torn properly and the notch-shaped groove is dug on the back of the cover so that it can always be torn to a certain shape. The characteristics of the airbag module are generally made of plastic material, and the plastic cover and the plastic steering wheel body, which are frame crystals, form the driver module assembly. The driver's seat module is attached to the steering wheel spokes. The module has a metal surface plate which serves as a mounting surface for the gas inflator, which is mounted on the module back plate. Is fitted to the wheel hub.

Subsequently, a technology related to a vehicle equipped with an airbag module has been disclosed by the present applicant in a front panel integrated airbag device of Korean Patent Application No. 1995-61915 (filed December 28, 1995).

The front panel integrated airbag device includes an airbag assembly for mounting an airbag by directly mounting the panel core of the front panel, an airbag door riveted to the airbag assembly, and a hinge determined when an airbag is operated at a lower end of the airbag door. It is to solve the inconvenience of having to change the entire front panel during A / S from the configuration provided to prevent the generation of gaps and gaps between parts due to malfunction of the airbag to improve the appearance quality of the product.

However, the conventional all-in-one panel-type airbag device is integrated with the airbag assembly and the airbag door with the front panel (instrument panel), but the lower part of the instrument panel on which the airbag module is mounted is partially folded toward the front side to surround the airbag door. The other instrument panel which is in contact with the lower end of the bent instrument panel can be supported by the instrument surrounding the airbag door while being bent to a certain length. As a narrow space is formed on the outside, foreign materials are laminated from the outside, which makes it difficult to deploy the airbag due to friction between the instrument panels, and a certain groove is formed in the exterior of the instrument panel where the airbag module is mounted. That has the problem.

The present invention is to solve such a conventional problem, the purpose of the airbag for passengers to make the hinge panel and the support panel integrally formed so that the hinge panel rigidity and smooth deployment can be made when the airbag is deployed It is to provide a connection device.
