Embodiment 1

[0118] Image 6 and Figure 7 It is a front view and a side view of an airbag cushion and a restricting device applied to a vehicle airbag device according to a first embodiment of the present invention.

[0119] In an embodiment of the present invention, the restricting device 60 may be provided with a first tether 61 having two ends connected to the seat 11 and the airbag cushion 20 .

[0120] For example, if Image 6 and Figure 7 As shown, the first tether 61 may be provided with a pair of first tethers installed between the side surfaces of the seat 11 and the front portions of the first pad 30 and the second pad 40 .

[0121] Such a first tether 61 may be prepared by using the same or similar fabric material as that of the airbag cushion 20 .

[0122] One end of the first tether 61 is fixed to the first pad 30 and the second pad 40 by sewing, and one end of the first tether 61 may be fixed to a frame (not shown) in the seat 11 .

[0123] In the event of a vehicle co...

Embodiment 2

[0132] Figure 8 and Figure 9 It is a front view and a side view of an airbag cushion and a restricting device applied to a vehicle airbag device according to a second embodiment of the present invention.

[0133] In a second embodiment of the invention, the restriction device 60 may include a pair of second tethers 62 mounted between the non-inflatable regions 37 and 47, the non-inflatable regions being inactive. So as not to be inflated by the first pad 30 and the second pad 40 and the first chamber wall 35 and the second chamber wall 45 in the seat 11 .

[0134] For example, the upper end of each second tether 62 is stitched to the inner or outer surface of the non-inflated regions 37 and 47 , and the lower end of the second tether 62 may be fixed to the frame in the seat 11 .

[0135] That is, according to the present invention, when the upper end of the second tether 62 is connected to the non-inflation regions 37 and 47 through the first chamber wall 35 and the second...

Embodiment 3

[0138] Figure 10 and Figure 11 It is a front view and a side view of an airbag cushion and a restricting device applied to a vehicle airbag device according to a third embodiment of the present invention.

[0139] In the third embodiment of the present invention, such as Figure 10 and Figure 11 As shown, the restraint device 60 may include a pair of third tethers 63 mounted on the exterior of the first pad 30 and the second pad 40 and then secured by the first pad 30 and the second pad 40 to seat 11.

[0140] That is, the upper end of the third tether 63 is connected to the front portion (that is to say, the front walls 302 and 402 of the first pad 30 and the second pad 40) and is disposed on the first pad 30 and the second pad. 40, the third tether 63 restricts the expanded shape of the airbag cushion 20 so as to prevent the first cushion 30 and the second cushion 40 from being divided to the outside.

[0141] In addition, the lower end of the third tether 63 is conn...

Abstract

The present invention relates to a vehicular airbag device provided with a configuration comprising an airbag cushion which is formed in a shawl shape so as to surround and restrict the entire upper body around both shoulders of an occupant as well as the abdominal and pelvic regions in the event of a vehicle collision, and deploys toward the both side surfaces of the occupant; and a limiting means which is installed in the first and second cushions of the airbag cushion that deploy at the both sides of the occupant, and provides a supporting force and limits the deployment shape of the first and second cushions upon deployment of same. Since both side surfaces and the front surface of the occupant are effectively restricted by improving the lateral strength of the airbag cushion, the occupant can be safely protected in the event of a vehicle collision.

Description

[technical field] [0001] The present invention relates to a vehicle airbag device, and more particularly, to a vehicle airbag device capable of safely protecting an occupant in the event of a vehicle collision by restraining an upper body around both shoulders of the occupant. [Background technique] [0002] In general, a vehicle airbag device is a safety device for protecting occupants in the event of a vehicle collision by injecting gas into the airbag according to a signal of an impact sensor to rapidly inflate the airbag. [0003] The airbag device is installed on a steering wheel or instrument panel, a seat, a side wall, etc. provided in a vehicle, and is inflated toward a front or side surface of an occupant in case of a vehicle collision to protect the occupant. [0004] That is, the vehicle may be provided with a front airbag deployed in front of a driver's seat and a passenger's seat, a curtain airbag and a side airbag deployed from the side of the occupant to prote...
