Definitions
- the present invention relates to an airbag device for protecting a passenger in a passenger seat of a vehicle.
- An airbag device for protecting passengers on the passenger seat side is installed inside an instrument panel (hereinafter referred to as “instrument panel”) on the passenger seat side of the vehicle.
- instrument panel an instrument panel
- the opening of the housing that stores the airbag is curved under the pressure generated by the inflation and deployment of the airbag.
- the curved opening cannot properly serve as a hinge when the lid is torn apart. This has caused a problem that the opening of the lid is hindered.
- Patent Document 1 a reinforcing member is used in order to prevent the opening from being bent.
- the present invention has been made in view of such a problem, and an object of the present invention is to provide an airbag device that minimizes deformation of a housing that houses an airbag and does not hinder the opening of the lid.
- a representative configuration of an airbag device includes a housing disposed inside an instrument panel of a vehicle, an airbag accommodated in the housing, and accommodated in the housing.
- An inflator that supplies gas to the airbag to inflate and deploy, and the housing has a front wall and a rear wall that are hooked on the lid at the upper end, a left wall, a right wall, and a bottom surface.
- the front wall and the rear wall are spaced apart from the left wall and the right wall at least from the upper end to a predetermined height, respectively, and are connected to the left wall and the right wall respectively by connecting portions in the vicinity of the upper end.
- the airbag when the airbag is inflated and deployed and pressure is applied to the four walls from the inside, the lower ends of the front wall and the rear wall are inclined outward, but almost the whole including the upper end is substantially flat. To be kept. Therefore, the upper end portions of the front wall and the rear wall that are hooked on the lid portion are hooked on the lid portion while being kept in a substantially straight shape without being curved. Therefore, when the lid portion is opened in a double-spread manner, the upper end portions of the front wall and the rear wall play a role as a hinge of the lid portion without problems, and hinder the opening operation of the lid portion when the airbag is inflated and deployed. It is possible to prevent.
- the front and rear walls are inherently highly rigid and difficult to deform even when pressure is applied from the inside. And since it is spaced apart from the left wall and the right wall as in the present invention, it is kept substantially flat. Furthermore, in this invention, there exists a connection part which connects between the walls which are spaced apart.
- the connecting portion is a weak and fragile portion that connects the walls only in a part near the upper end of the housing.
- the front wall and the rear wall which are highly rigid and maintained in a substantially flat plate shape, pull the left wall and the right wall by the fragile connecting portion in the vicinity of the upper end thereof. .
- the lower end portion of the front wall and the rear wall that is separated from the left wall and the right wall is inclined outward as described above, but almost the whole including the upper end portion is lowered by the deformation of the lower end portion.
- a behavior peculiar to the present invention that it is kept flat is generated.
- the opening of the housing will not bend even if the whole descends, and the role of the lid as a hinge will not be impaired. Further, unlike the technique using an additional reinforcing member, the weight of the housing itself that stores the airbag is not increased.
- ⁇ Separation means that the left wall and the right wall are not continuous among the parts constituting the front wall and the rear wall.
- the front wall and the rear wall may be terminated before the bottom corner, and the connecting portion may connect the front wall and the rear wall to the left wall and the right wall over the corner.
- the front wall and the rear wall having high rigidity are not extended to the corner, but are terminated at the front, so that the weakness of the connecting portion is maintained and the behavior specific to the present invention is obtained.
- connecting the front wall and the rear wall to the left wall and the right wall, respectively, over the corners is limited to a weak connection.
- the “corner” refers to a virtual line portion or a virtual point portion where front, rear, left and right wall portions intersect.
- the above connecting portion may have a shape in which a part of the front wall or the rear wall is extended and bent.
- the connecting portion is a thin member obtained by extending a part of the front wall or the rear wall having high rigidity, so that the fragility is maintained. Further, the connecting portion can be integrally formed with the front wall or the rear wall, and the number of man-hours can be reduced. Furthermore, an excessive weight increase of the airbag device can be avoided as compared with a case where the connecting portion is an independent member and is attached to the housing by welding or the like.
- the front wall and the rear wall may have a hooking member that is hooked on the lid, and the connecting part may have a shape in which a part of the hooking member is extended and bent.
- the retaining member plays a role as a batten (sparing tree) that maintains the rigidity of the front wall and the rear wall. If a connecting portion is formed by extending the hooking member as it is, the rigidity of the connecting portion is increased. Therefore, a part of the latch member is extended to form a thin connecting portion, and the weakness is maintained. Even with the above-described configuration, it is possible to avoid a reduction in man-hours and an excessive increase in weight of the airbag device.
- the above-mentioned front wall or rear wall may have one or more cutouts at the lower end.
- the weakness of the lower end portion of the front wall or the rear wall is increased.
- the rigidity of the upper end portion is relatively increased, and deformation that inclines to the outside of the lower end portion of the front wall or the rear wall is promoted.
- the above-mentioned bottom surface may have an extended cutout portion cut out at a position corresponding to the cutout portion.
- an airbag apparatus includes a housing disposed inside an instrument panel of a vehicle, an airbag accommodated in the housing, an airbag accommodated in the housing, and an airbag.
- An inflator that supplies gas to the bag to inflate and deploy, and the housing has a front wall and a rear wall that are hooked on the lid at the upper end, and a bottom surface, and the front wall and the rear wall are It has the connection part which connects each other by the upper end, and the front wall and the rear wall are terminated before the corner of the bottom face.
- the lower part of the wall is inclined outward as described above, but almost the whole including the upper part of the wall is lowered by the deformation of the lower part of the wall, but is kept flat. Inventive behavior occurs.
- the front and rear walls are inherently highly rigid and difficult to deform even when pressure is applied from the inside.
- the connecting portion that connects the front wall and the rear wall is a fragile portion with low rigidity because the connection is performed at a limited portion called the upper end.
- the front and rear walls having high rigidity are not extended to the corner, but are terminated at the front, so that the weakness of the connecting portion is maintained and the behavior specific to the present invention is obtained. In other words, connecting the front wall and the rear wall over the corner and front and rear is limited to the weak connecting portion.
- the above-mentioned front wall or rear wall should have a thickness at the top of the wall that is greater than the thickness at the bottom.
- the weakness of the lower part of the front wall or the rear wall is increased, and as a result, the rigidity of the upper part of the wall is relatively increased, and the deformation of the lower part of the wall that is inclined outward is promoted.
