Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in an airbag device for protecting an occupant from an impact by inflating an airbag at the time of a collision of an automobile or the like.

[Conventional technology]

In recent years, as a cushioning system that supports a seat belt device for safely holding the occupants of the vehicle in the seat, in the event of a collision, the occupant's body, especially the head and chest, is received by a balloon-shaped airbag, and then the interior 2. Description of the Related Art An airbag device has been put to practical use in which a shock-absorbing stroke is gained by gradually releasing gas to suppress an impact force applied to a human body.

In such an airbag device, for example, a module composed of a center pad, a folded airbag, an inflator (gas generator) and the like is housed in a steering wheel, and an electric signal from a sensor for detecting a collision of the vehicle is provided. Ignites the inflator and instantaneously inflates the airbag with the rapidly burned gas. Therefore, when the airbag device is operated, the upper wall of the center pad is broken by the inflation pressure of the airbag, and the airbag is expanded from the broken opening so that the airbag can largely inflate above the center pad. Further, when the module of the airbag device is provided in the instrument panel, when the airbag device is operated, the airbag cover is broken or expanded by the inflation pressure of the airbag, and is expanded.

[Problems to be solved by the invention]

However, a method of processing the airbag device (particularly, a module) after such an operation is not generally known, and it is necessary to refer to a guide such as an owner's manual or a service manual. For example, appropriate processing is required for procedures of disposal and replacement of the airbag module after operation, handling of the control unit after operation, and the like. That is, the harmful inflator burnt waste must not be dumped as it is, or the control unit must not be independently repaired.

Therefore, a repair worker must look at the service manual of each vehicle type, but it is almost impossible for an old car. In addition, it is necessary to consider whether to actually see the service manual or the owner's manual, and appropriate information is promptly needed.

Further, when the occupant has no prior knowledge at all, and the guide is not at hand, there is a problem that the airbag device cannot be processed immediately after the operation. Further, even if the guide is at hand, the occupant who has encountered the accident cannot afford to look at the guide calmly, and it is difficult to quickly process the airbag device after activation.

Further, as shown in FIGS. 9 and 10, the airbags 1, 7, which have been inflated once as indicated by the two-dot chain line in FIG. Or it hangs down from the instrument panel 8,
Very bulky. For this reason, in this state, the airbag 1 or 7 occupies the vehicle interior space while hanging down from the steering wheel 10 or the instrument panel 8, so that when the vehicle travels after the airbag device is activated, it hinders the driving operation. The airbags 1 and 7 hinder the work during repair and maintenance work of the vehicle body.

That is, an object of the present invention is to solve the above-described problems, and to prevent a withdrawn airbag after activating an airbag device from occupying a cabin space and hindering a driving operation, a repair, and a maintenance operation. Another object of the present invention is to provide an easy-to-use airbag apparatus capable of promptly performing appropriate post-processing of a part requiring repair or replacement.

[Means for solving the problem]

An object of the present invention is to provide an airbag device having an airbag that inflates during a vehicle collision to protect an occupant from an impact, and a cover that covers the airbag and that can be deployed when the airbag is inflated. The present invention is attained by an airbag device characterized in that a processing method of the airbag device after activation is displayed in a appearing portion.

[Action]

According to this invention, the processing method of the airbag device after the operation is displayed in a portion that appears after the operation of the airbag device, so that the occupant or the repair worker can use the guidebook describing the processing method of the airbag device after the operation. Even without taking out, the processing method can be quickly known.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The airbag device shown in FIG. 1 and FIG. 2 instantaneously inflates a center pad, which is a cover disposed over the boss of the steering wheel 10 so as to cover the airbag 1, and the folded airbag 1. (Not shown) which is a gas generating device.

The center pad is formed of a soft synthetic resin such as urethane or the like, which is formed by injection molding with a net insert embedded therein.When the airbag is inflated, the upper wall 2a, 2b is broken into substantially uniform divided pieces and developed. The part is formed in a substantially H shape.

Further, as in the airbag device shown in FIG. 1, for example, a rectangular display slip 4 describing an airbag storing method as shown in FIG. I have. The display form 4 is formed of a flexible member, and is folded together with the airbag 1 when the airbag 1 is stored in the center pad.

Therefore, when the airbag device is activated to protect the occupant in the event of a vehicle collision, the airbag 1 is inflated by the gas generated from the inflator while breaking the upper walls 2a, 2b of the center pad and greatly inflated above the center pad.
The display slip 4 is developed in front of the occupant. Such an inflated state of the airbag 1 is maintained for a certain period of time as one stroke of the operation stroke of the airbag device, so that the occupant can know the presence of the display slip 4 during that time.

Therefore, the occupant can read the description of the airbag storage method on the display slip 4 after the operation of the airbag device, and can immediately store the airbag 1 in accordance with the description. Of course, the repair worker can also see the description of the display slip 4 during the repair work.

In addition, for example, according to the airbag device based on another embodiment shown in FIG. 2, a display tag 3 as shown in FIG. 5 is attached to the back surface of the upper wall 2a of the center pad,
The display tag 4 is also provided on the upper surface near the fixed portion side of the airbag device 1.
Is affixed.

Then, when the airbag device is operated and once inflated, gas is exhausted from the exhaust port and the airbag 1 hangs down from the steering wheel 10, the display card 3 attached to the back surface of the upper wall 2a of the expanded center pad is opened. , And an indicator 4 attached to the upper surface of the airbag 1 is deployed to the front of the occupant.

Therefore, the occupant and the repair worker can read the description of the airbag storage method on the display slips 3 and 4 after the airbag device is activated, and can immediately store the airbag 1 in accordance with the description.

Next, FIG. 3 and FIG. 4 are perspective views of an airbag device for a passenger seat according to another embodiment of the present invention when an airbag device module is disposed inside the instrument panel 8. . The airbag device for a passenger seat is an airbag cover 9 disposed above an instrument panel 8 so as to cover the airbag 7, and an inflator which is a gas generating device for instantly inflating the folded airbag 7. (Not shown).

At a substantially center of the surface of the airbag 7 in the passenger airbag device shown in FIG. 3, a rectangular display slip 5 describing an airbag storing method as shown in FIG. 7 is attached. The display tag 5 is formed of a flexible member, and is folded together with the airbag 7 when the airbag 7 is stored in the airbag cover 9.

Then, a passenger airbag device for protecting the occupant in the event of a vehicle collision is activated, and the gas generated from the inflator causes the airbag 7 to inflate while deploying the airbag cover 9 and greatly inflate above the instrument panel 8. Then, as shown in FIG.
Is deployed in front of the crew. The deflated state of the airbag 7 lasts for a certain period of time as one stroke of the operation of the airbag device for the passenger seat, so that the occupant can know the presence of the display slip 5 during that time.

Accordingly, the occupant can read the description of the airbag storage method on the display slip 5 after the passenger seat airbag device is activated, and can immediately store the airbag 7 in accordance with the description. Also, by attaching a display tag 6 as shown in FIG. 8 to the back surface of the airbag cover 9, the occupant or the repair worker can read the instruction manual (guide book) according to the description of the display tag 6, and It is possible to know a detailed processing method of the airbag device after the operation, such as a procedure for disposing and replacing the airbag mold and a method for handling the control unit after the operation. That is, it is possible to prevent an erroneous airbag device processing method in which harmful inflator burnt waste is directly dumped or a control unit is independently repaired.

In each of the above embodiments, the processing method of the airbag device is displayed by attaching a rectangular display tag to the front surface of the airbag or the back surface of the cover, but the present invention is not limited to this. The contents may be printed directly on the surface of the airbag or transferred to the back of the cover.
Further, it is needless to say that such a display means can be provided on one or both of the front surface and the back surface of the airbag, and the display contents describing the processing method of the airbag device after the operation is also described above. Needless to say, the present invention is not limited to the contents of the embodiment.

Furthermore, it goes without saying that the shape of each airbag cover can also take various shapes.

[Effect of the invention]
