Embodiment approach

[0044] Below, use Figure 1 to Figure 11 Embodiments of the present invention will be described.

[0045] Such as figure 1 As shown, the airbag device 11 has a safety device that covers the side and front parts of the occupant 2 seated on the vehicle seat 1, such as the head 2a, neck 2b, shoulder 2c, upper arm 2d, chest 2e, and waist 2f. airbag12. The airbag 12 as figure 2 As shown in , it shows a flat state before being rolled up in a roll shape or folded in a bellows type, and is provided with an inflator 13 for blowing gas into the inside.

[0046] The vehicle seat 1 is provided with a seat cushion 1a and a backrest 1b. A headrest 1c is integrally formed on the upper part of the backrest 1b or a headrest 1c is additionally attached thereto. Refer to figure 1 (a). The seat cushion 1a and the backrest portion 1b are supported by a frame 1d.

[0047] The inflator 13 is formed in a cylindrical shape and has a structure for ejecting gas from its outer surface, for example...

Abstract

Provided is an airbag device in which, during a collision, a hood-type airbag is inflated and deployed in a state of being exactly sandwiched between a seated occupant shoulder and a seatbelt in a normally set state, thereby reducing injury to an occupant due to devices other than airbags such as seatbelts. This airbag device (11) is provided with: an airbag (12) that integrally covers the head (2a) and side sections of a seated occupant (2); and an inflator (13). The airbag (12), which is in a flat state before being folded, has a plurality of chambers (12c) divided in the longitudinal direction. The chamber (12c) has a head protection chamber (12ca) housed in the upper part of the backrest part (1b) of the seat (1), and a pair of side protection chambers (12cb) housed in opposite positions spaced apart in the vehicle width direction at both left and right side parts of the backrest part (1b). The airbag (12) is configured such that, when the airbag (12) is inflated and deployed, theside protection chamber (12cb) is inflated and deployed between the seat belt (3) and the occupant (2), thereby forming a space (S) between the airbag (12) and the occupant (2) that can be deployed ata position through which the seat belt (3) passes.

Description

technical field [0001] The present invention relates to an airbag device for protecting, for example, the head of an occupant seated on a vehicle seat, a shoulder, an upper arm, a side portion of a chest, and a part of the front of an occupant during a vehicle collision, And depending on the situation, the occupant's abdomen and the side of the waist are also protected. [0002] Hereinafter, in the present application, "up" and "upper" refer to the direction of the head of the occupant sitting on the seat in a regular state, and "down" and "under" refer to the direction of the foot of the occupant. In addition, "front" and "front" refer to the front direction of the occupant sitting on the seat in a regular state, and "rear" and "rear" refer to the rear direction thereof. In addition, "left" and "left side" refer to the direction of the left hand of the occupant sitting on the seat in a normal state, and "right" and "right side" refer to the direction of the right hand of the...
