Description

  The present invention relates to an airbag device for a passenger seat of an automobile, and more particularly to an occupant protection device in an out-of-position position.

  Conventional airbag system for passenger seats of automobiles, especially in order to protect out-of-position, that is, when the occupant to be protected is outside the proper location for protection, the airbag body is seated in the correct position. A front panel that gives restraining force to the child and a bottom panel that is adjacent to the front panel and partially touches the instrument panel while the front panel is inflated and deployed, so that a large load is not applied to the child's neck The thing (prior art document 1) is known as a prior art.

  However, in the conventional technique, since the bottom panel is added to the front panel, there is a possibility that the airbag body becomes bulky when the airbag body is folded, the weight increases, and the manufacturing cost increases.

  In order to solve the above-described problems, the present invention provides an airbag device for a passenger's seat of an automobile that is not bulky when the airbag body is folded, is lightweight, and has a low manufacturing cost.

  In order to solve the above problems, an airbag device for a passenger seat according to claim 1 of the present invention includes an inflator that detects a sudden braking at or near a collision and ejects gas, and an ejection from the inflator An airbag device for a passenger's seat of an automobile comprising an airbag body that can be inflated and deployed by the gas, wherein the airbag body is folded in a bellows shape, and the first accumulation portion And a second stacking portion that can be raised from the lower hinge portion and restrained from the front at a position corresponding to the face of the occupant.

  According to a second aspect of the present invention, there is provided an airbag device for a passenger seat of an automobile, wherein the gas from the inflator can be initially sealed in the second stacking portion according to the first aspect.

  According to the first aspect of the present invention, an airbag device for a passenger seat of an automobile can be inflated and deployed by an inflator that detects a sudden braking at or near a collision and ejects gas, and the gas ejected from the inflator. An airbag device for a passenger's seat of an automobile comprising an airbag body, wherein the airbag body rides on a lower side of a first stacking portion that is folded in a bellows shape and an upper portion of the first stacking portion. It is possible to get up around the hinge part of the vehicle, and to be composed of a second stacking part that can be restrained from the front to the position corresponding to the occupant's face, so even if the occupant is out of position, Since it can be restrained, it has the effect of ensuring occupant protection.

  In addition, according to the second aspect of the present invention, since the gas from the inflator can be sealed first in the second accumulating portion, there is an effect that a system for protecting an occupant can be quickly established.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a passenger-side airbag device for an automobile in which an airbag main body according to Embodiment 1 of the present invention is inflated and deployed to secure a passenger. The perspective view of the airbag apparatus for passenger seats of the motor vehicle which expanded and expanded the airbag main body of FIG. The expanded sectional view of the airbag main body of FIG.1 and FIG.2.

  Hereinafter, embodiments of the present invention will be described in detail. The purpose of the present invention is to provide an airbag device for a passenger seat of an automobile that is not bulky when the airbag body is folded, is lightweight, and has a low manufacturing cost, and detects sudden braking at or near a collision. An airbag device for a passenger seat of an automobile comprising an inflator that ejects gas and an airbag body that can be inflated and deployed by the gas ejected from the inflator, wherein the airbag body is folded in a bellows shape And a second stacking portion that can ride on the upper portion of the first stacking portion and rise up around the lower hinge portion and can be restrained from the front at a position corresponding to the face of the occupant. That was realized. Embodiments of the present invention will be described below with reference to the drawings.

  A structure according to the first embodiment of the present invention will be described with reference to FIGS. The airbag apparatus 1 for a passenger seat of a vehicle according to the first embodiment includes a sensor (not shown) that detects sudden braking or the like near a collision, an inflator 2 that ejects gas by a signal from the sensor, and the inflator And an airbag main body 3 that can be inflated and deployed by the gas ejected from 2.

  The airbag body 3 can be raised around a first stacking portion 4 that is folded in a bellows-like manner and an upper portion of the first stacking portion 4 and has a lower hinge portion 5 at a position corresponding to the occupant's face. It is comprised from the 2nd stacking part 7 which becomes a flat surface from the front and can be restrained.

  Further, the second accumulator 7 is folded so that the gas from the inflator 2 can be sealed first. Reference numeral 6 denotes a surface of the second stacking unit 7 that is restrained from the front on the face of an occupant (not shown).

  Reference numerals 8a, 8b, and 8c are portions of the airbag main body 3 that are inserted together, and the airbag main body 3 can be inflated by gas sealing described later. Reference numeral 9 is an instrument panel, 10 is a restrained passenger, 11 is a front pillar, 12 is a center pillar, and 13 is a side member.

  Next, the operation of the first embodiment will be described.

  An airbag device 1 for a passenger seat of an automobile includes an inflator 2 that detects a sudden braking near or close to a collision and ejects gas, and an airbag body 3 that can be inflated and deployed by the gas ejected from the inflator 2. An airbag device 1 for a passenger's seat of an automobile, wherein the airbag main body 3 has a first stacking portion 4 folded in a bellows shape, and rides on an upper portion of the first stacking portion 4 and has a lower hinge. Since the second stacking unit 7 is configured to be able to get up around the part 5 and be restrained from the front to the position corresponding to the face of the occupant, even if the occupant is out of position, the position corresponding to the face of the occupant can be viewed from the front. Since it can be restrained, it has the effect of ensuring occupant protection.

  In addition, since the gas from the inflator 2 can be sealed first in the second accumulator 7, there is an effect that a system for protecting the occupant can be quickly established.
