Embodiment approach 1

[0044] figure 1 is a perspective view of an airbag apparatus for a vehicle according to a first embodiment of the present invention, and figure 2 for figure 1 a plan view of an airbag device for a vehicle as shown, and image 3 An expanded view of the airbag cushion.

[0045] The airbag apparatus 10 for a vehicle according to a preferred embodiment of the present invention may include an airbag cushion 20 formed in a shawl shape and deployed toward both lateral sides of an occupant to surround the occupant upon a vehicle collision. and the inflator 21 that generates gas in response to a collision detection signal to supply the gas into the airbag cushion when the vehicle collides.

[0046] The airbag cushion 20 is inflated and deployed toward both lateral and front sides of the occupant, and performs a function of protecting the occupant safely by restraining the head portion, chest, abdomen, and pelvis portions around the occupant's shoulders.

[0047] To achieve this,...

Embodiment approach 2

[0092] Hereinafter, the configuration of an airbag apparatus for a vehicle according to a second embodiment of the present invention will be described in detail.

[0093] Figure 6 is a front view of an airbag apparatus for a vehicle according to a second embodiment of the present disclosure.

[0094] Such as Figure 6 As shown, both ends of the seat belt 16 are installed at the upper and lower ends of the center pillar (so-called B-pillar) 16 in the driver's seat 11 of the vehicle to which the ordinary seat belt 15 is applied, and A buckle 17 is installed at the lower right portion of the passenger seat 11 so that the tongue of the seat belt 15 is coupled thereto.

[0095] Therefore, when the airbag cushion 20 described in the above-mentioned first embodiment is applied to a vehicle to which a general seat belt is applied, there is a problem that the seat belt 15 and the second cushion 40 interfere with each other.

[0096] Therefore, the airbag apparatus 10 for vehicles a...

Embodiment approach 3

[0101] Figure 7 and Figure 8 is an illustration of an airbag apparatus for a vehicle according to a third embodiment of the present invention.

[0102] Figure 7 is a rear view showing the airbag cushion inflated and deployed, and Figure 8 It is a perspective view showing a state where an inflated and deployed airbag cushion collides with an occupant in a rear seat.

[0103] Such as Figure 7 and Figure 8 As shown, the airbag cushion 20 may also include a third cushion 60 to protect rear seat occupants in the event of a vehicle collision.

[0104] The third pad 60 is connected to the lower end of the connection part 50 and may be inflated and deployed downward along the rear surface of the backrest 12 .

[0105] At least one fourth chamber wall 61 may be formed in the third gasket 60 to define the third gasket 60 to a plurality of chambers.

[0106] For example, a pair of fourth chamber walls 61 spaced apart from the upper end of the third gasket 60 by a predetermin...

Abstract

The present invention relates to an airbag device for a vehicle. The airbag device comprises: an airbag cushion which is formed in a shawl shape and deployed toward both sides of a passenger so as towrap and restrain the entire upper body around both shoulders of the passenger when a vehicle collides; and an inflator for generating gas and supplying the gas to the airbag cushion in response to animpact detection signal when the vehicle collides. Accordingly, when a vehicle collides, the shawl-shaped airbag cushion installed on the back of a seat is inflated and deployed to restrain the bothsides and front area of the upper body of a passenger around both shoulders of the passenger, thereby safely protecting the passenger.

Description

technical field [0001] The present invention relates to an airbag apparatus for a vehicle, and more particularly, to an airbag apparatus for a vehicle that restrains an upper body of an occupant around both shoulders of the occupant to protect the occupant in safety when the vehicle collides. Background technique [0002] In general, an airbag apparatus of a vehicle is a safety device that protects occupants by rapidly inflating the airbag by injecting gas into the airbag according to a signal of an impact detection sensor when the vehicle collides. [0003] Such an airbag device is installed in a steering wheel, an instrument panel, a seat, a side wall, etc. provided in a vehicle, and inflates toward the front or side of an occupant to protect the occupant when the vehicle collides. [0004] That is, the vehicle may be provided with a front airbag deployed in front of a driver's seat and a passenger seat, a curtain airbag deployed from the side of a passenger to protect the...
