Abstract

(57) [Abstract] [Purpose] An airbag, which is mounted on a vehicle to support the body of an occupant, is deployed to a predetermined position regardless of an external force such as an oblique collision. [Structure] Instrument panel 2 attached to vehicle body 1
1 is provided with a deployment port 6 for the airbag 5, and the side wall surface 9 of the meter hood 3 is erected along the side portion of the deployment port 6 for the airbag 5. When the airbag 5 is deployed from the deployment port 6, the meter hood 3 along the side of the deployment port 6
The side wall surface 9 of the airbag 5 extends forward while being in contact with the edge portion of the airbag 5 and can be deployed at a predetermined position to support the body of an occupant. It can be deployed at a predetermined position by being restricted by the side wall surface 9 or the door inner wall 10 in the vehicle.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for mounting an airbag installed on a front seat of an automobile.

[0002]

[Prior Art]

 Conventionally, an airbag is mounted in front of a seat in order to prevent a passenger from falling forward when an automobile collides with an obstacle ahead. An automobile equipped with this airbag will be described with reference to FIG. In the figure, a meter hood 3 for covering the meters necessary for driving is formed on an instrument panel 2 in the front part of a vehicle body 1, and a steering 4 is arranged in front of the meters. A dashboard (not shown) and a deployment port 6 for the airbag 5 are provided on the passenger side. The meter hood 3 may use the inner wall of the meter hood to allow air to flow on the meter surface (see Japanese Utility Model Laid-Open No. 58-147830). Further, the airbag 5 is appropriately provided with a tether (hanging cloth) inside the airbag 5 so that the airbag 5 having the large shape can be maintained in a predetermined direction when deployed. Then, when the vehicle collides, it is deployed in a predetermined direction from the opening 6 to prevent the occupant from falling.

[0003]

[Problems to be solved by the device]

 However, since the shape of the airbag 5 when deployed is large, when the airbag 5 is deployed, it may not be possible to properly regulate the balance of spreading to the left and right. That is, as shown by the one-dot chain line (center line) and the two-dot chain line in FIG. 4, the vehicle deploys straight to the occupant, but when the vehicle collides diagonally, external force in the left-right direction is applied to the airbag 5. Also, in some cases, the body moves diagonally due to the reaction of the collision, and the air bag 5 and the body are displaced and come into contact with each other, so that the buffer function cannot be sufficiently exerted. As a countermeasure for this, there are cases where multiple tethers are combined to improve the direction, but the effect was not expected because the cost increased.

An object of the present invention is to provide an airbag mounting structure that supports the direction of deployment of an airbag mounted on a vehicle.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an airbag deployment port on one side of an instrument panel in which meters are arranged, and a side wall surface of a meter hood covering the meters is installed as a deployment port of the airbag. It is characterized by being placed along the side.

[0006]

[Action]

 Since the present invention is configured as described above, when the airbag is deployed from the deployment port, the side edge of the meter hood along the side of the deployment port contacts the front edge of the airbag while the edge of the airbag is in contact. And is deployed in place. Also, due to the impact in the diagonal direction, even if the lateral force acts on the airbag, the deploying direction is restricted by the side wall surface or the inner wall of the door in the vehicle.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the instrument panel 2 attached to the vehicle body 1 has a deployment port 6 of the air bag 5 formed rearward on one side and a meter hood 3 adjacent to the deployment port 6. Has been formed. A meter 7 and a warning lamp 8 are attached inside the meter hood 3. Further, both side wall surfaces 9, 9 of the meter hood 3 are formed so as to stand upright at the edge portion of the deployment port 6 and the end portion side of the instrument panel 2. The airbag 5 is usually housed inside the instrument panel 2. Also, 4 is steering and 10 is the inner wall of the door in the car.

Next, the operation will be described. When a vehicle collides with an obstacle ahead while the vehicle is running, the body of the occupant leans forward. At this time, the airbag 5 is deployed from the deployment port 6 to support the body of the occupant. When the airbag 5 is deployed, the edge of the airbag 5 inside the vehicle body 1 comes into contact with the side wall surface 9 of the meter hood 3 and extends along the side wall surface 9. On the other hand, the other edge portion of the airbag 5 extends along the inner wall 10 of the door. As a result, the airbag 5 is stable and can support the body even when the vehicle that has collided is oriented diagonally and the body is diagonally moved.

Further, since the deployed position of the airbag 5 is stable and the meter hood 3 is enlarged as compared with the conventional one, the visibility is improved, and the degree of freedom in layout of the meter 7 and the warning lamp 8 is increased. Will increase. Further, since the meter hood 3 can be integrally molded with the instrument panel 2, the cost can be maintained without the need for additional parts or additional processing even if the shape is changed.

[0010]

[Effect of the device]

 Since the present invention is configured as described above, when the airbag is deployed from the deployment opening, the edge of the airbag comes into contact with the side wall surface of the meter hood along the edge of the deployment opening. While extending forward, it can be deployed at a predetermined position to support the occupant's body, and the airbag can be deployed at a predetermined position by being regulated by the side wall surface or the inner wall of the door inside the vehicle even when an external force in the left-right direction acts. You can
