Abstract

The invention provides an airbag device capable of reliably restraining a seated occupant regardless of the posture of the occupant. The present invention is an airbag device mounted on a vehicle seat having a seat cushion forming a seat surface and a backrest forming a backrest cushion, the airbag device having a pair of inflators housed in left and right side portions of the backrest and generating inflation gas, and an airbag accommodated in the backrest in a curled or folded state and deployed by the inflation gas discharged from the inflator. Furthermore, the airbag is configured so as to have a pair of left and right side chambers which deploy forward from a side portion of the backrest and which restrict movement of at least a waist portion to a shoulder portion of the occupant, and a connection portion which connects the pair of side chambers and is positioned above a head portion of the occupant when the airbag is deployed.

Description

technical field [0001] The invention relates to a vehicle seat and a safety airbag device installed on the seat. In particular, it relates to an airbag device capable of reliably restraining an occupant regardless of the posture of the occupant. Background technique [0002] It is well known that one or more airbags are installed on a vehicle in order to protect occupants in the event of a vehicle accident. For example, the airbag is inflated and deployed from the center of the steering wheel to protect the driver; it is deployed downward on the inside of the window to protect the occupant when the vehicle is hit laterally or rolls over. Curtain airbags; and side airbags that are deployed between the occupant and the side panels to protect the occupants when the vehicle is subjected to a lateral impact. [0003] In recent years, with the advancement of autonomous vehicle technology, occupants are expected to sit in various relaxed postures, such as reclining the seat great...
