Of course, the entire vehicle body 1a may be covered with the sound insulating cover 25.

  The sound insulation cover 25 is for preventing as much as possible the situation where the explosion sound of the airbag device 2 generated in the vehicle 4 is dissipated outside the vehicle 1, and therefore does not necessarily need to cover the entire vehicle body 1a. It may be below the minimum reference value.

  However, in consideration of noise inconveniences such as in the vicinity, preferably, one end portion 25a of the sound insulation cover 25 is grounded in close contact with the floor surface of the left door of the vehicle 1 while the vehicle 1 is covered while the floor surface of the right door is covered. The other end 25b is grounded in close contact. It is not a limiting requirement of the invention that the left and right end portions 25a and 25b of the sound insulating cover 25 are brought into close contact with the floor surface 24 completely.

  Further, in this embodiment, as shown in FIG. 4, the sound insulation cover 25 has skirt portions 26, 26 connected to the left and right end portions 25 a, 25 b, and these skirt portions 26, 26 are located on the left and right sides of the vehicle 1. It is in close contact with the floor. In addition, since the suction box 15 of the exhaust means 13 is disposed outside the sound insulating cover 25, one of the skirt portions 26 is on the middle portion of the suction hose 14. The skirt portions 26 and 26 may be provided only at one end.

An example of the deformable sound insulation cover 25 will be described with reference to FIG. Sound insulation cover 25 includes a cover main body 27 to easily deform the covered Ru side (the vehicle 1 side), and the elasticity of the sound absorbing material 28 which is furnished in the cover body 27, left and right end portions 25a of the cover body 27, 25b And skirt portions 26, 26 which are provided continuously.

Then, at least the peripheral end portions of the outer sound insulation cover 27a and the mesh-shaped inner gap cover 27b are appropriately attached.

  Therefore, the cover main body 27 is easily deformed inward as compared with the case of bending outward. By the way, the outer sound insulation cover 27a is intended to prevent a situation where sound leaks to the outside as much as possible. Therefore, the outer sound insulation cover 27a is a non-gap cover body and is made of a suitable synthetic fiber that can exhibit a sound absorbing effect other than cloth. Or ceramic fiber is employ | adopted arbitrarily.

  In addition, the sound absorbing material 28 is made of one or more materials having a property of absorbing sound, for example, foaming properties, ceramic fiber properties, sponge properties, and rubber properties. In this embodiment, a foaming elastically displaceable sound absorbing plate is employed.

D is a step in which the airbag apparatus 2 is deployed by energizing the electrical apparatus 3 with the airbag apparatus 2 mounted on the vehicle. In the airbag device deployment step D, the airbag device 2 that has undergone the electrical connection step A is deployed as it is without removing the airbag device 2 from the vehicle 1.

  Therefore, when the electrical connection process A is performed for an object in the steering wheel on the driver's seat side or an object in the instrument panel on the passenger seat side, a plurality of switches of the electrical processing device 3 are used. Each of 9a is pressed or automatically energized sequentially. In such a case, a plurality of airbag devices 2 can be deployed in order. The electrical connection process A is as already described.

(5) In-vehicle gas discharge process E
E is an in-vehicle gas discharge process for discharging the gas 31 generated when the airbag device 2 is deployed to the outside of the vehicle 1 through the discharge means 13 having the flexible suction hose 14. When the airbag device 2 is deployed, gas (white smoke: non-hazardous particulates) is generated in the vehicle interior 4 during deployment. In this in-vehicle gas discharge process E, the drive source 18 of the exhaust means 13 is activated at least immediately before, simultaneously with, and immediately after the airbag device 2 is deployed. When the drive source 18 is activated, the gas (gas) 31 in the vehicle interior 4 is sucked into the suction box 15 via the suction hose 14 and discharged to the outside (for example, a gas processing device) via the discharge fan 17. To do. At this time, the suction box 15 is equipped with a neo-genetic filter, so that a clean gas is discharged.

In this embodiment, a part of the vehicle body 1a (the left and right doors and the upper part corresponding to the ceiling) is covered. However, as described above, the vehicle body 1a may be entirely covered. Further, the skirt portions 26, 26 connected to both ends of the sound insulating cover 25 are not a specific requirement of the present invention. Therefore, both end portions or one end portion of the sound insulating cover 25 may be slightly separated from the floor surface 24.

  Next, D is a step in which the airbag device 2 is deployed by energizing through the electrical processing tool 3 while the airbag device 2 is mounted on the vehicle.

At this time, in the automatic mode, the timer 9b is started, and the airbag device 2 is sequentially deployed.

  Thus, “explosive sound generation” occurs during deployment, but the explosion sound generation is primarily shielded by the vehicle body 1a, and the sound leaked from the vehicle body 1a is secondarily absorbed by the sound insulation cover 25. Sound insulation. The sound insulation cover 25 according to the present embodiment includes a cover main body 27 and a sound absorbing material 28 built in the cover main body 27. The cover main body 27 is integrally attached to the outer sound insulation cover 27a and has a large number of sound. Since the inner gap cover 27b having the passage hole is provided, the sound absorbing property and sound insulating property are very excellent.

  By the way, although not particularly illustrated, as an additional requirement of the present embodiment, an odor treatment device may be provided directly or indirectly on the discharge side of the discharge means 13. In this odor treatment apparatus, for example, an odor eliminating filter for cleaning and removing odorous fine particles in an atmosphere generated during deployment on a movable box is disposed on the gas guide channel.

  Next, E is an in-vehicle gas discharge process for discharging the gas 31 generated when the airbag device 2 is deployed to the outside of the vehicle 1 through the discharge means 13 having the flexible hose 14. In the present embodiment, the drive source 18 of the discharge means 13 is a discharge fan with a filter, so that gas fine particles generated in the vehicle interior 4 during deployment are received through the filter.

  First, in the example shown in the embodiment of the invention, an opening for the flexible suction hose 14 is formed in a portion near one end of the sound insulation cover 25, and the suction hose 14 is connected through the opening. It may be inserted into the opening window of the vehicle 1.
