Embodiment

[0035] The airbag device in this embodiment includes: a fixing bolt 23 , a fixing piece 24 , an elastic band, an air duct 12 , a gas generator 11 , a fixing belt 21 , an airbag box 1 and a deadbolt 22 . The fixing bolt 12 is used to fasten the fixing piece 24 on the frame of the seat 4. The fixing piece 24 contains a hole, and the hole is sewn with an elastic band. .

[0036] The safety belt 2 runs through the through hole in the center of the airbag box 1, and it acts on the seat belt 2 to restrain the occupant 3, and fix the airbag box 1 on the thigh and lower abdomen of the occupant 3. One end of the fixing belt 21 is sewed with the edge of the airbag box 1, and the exposed part of the fixing belt 21 is sewed with a male Velcro, and can be bonded with the female Velcro that is sewed on the corresponding position on the safety belt 2 for fixing the airbag box 1. The lock tongue 22 can be fixed with the buckle on the seat 4 , so that the seat belt is restrained on the seat 4...

Abstract

The invention relates to a safety air bag device which comprises a seat safety belt and a safety air bag box fixedly arranged on the safety belt, and a safety air bag connected with an air generator is arranged in the safety air bag box. When the safety air bag is expanded, a safety air bag is formed, and the safety air bag comprises a first cavity for restraining frontward movement of the hip of a passenger; and a second cavity which is used for protecting the head and the chest of the passenger; the second cavity is located above the first cavity, the first cavity abuts against the thighs and the lower abdomen of a passenger, and the second cavity is located in front of the passenger. Compared with the prior art, the device has the advantages that the space of the steering wheel is released, and a driver can still be protected in an automatic driving state.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an airbag device. Background technique [0002] When a car collides, the front airbag on the driver's side is inflated to form a cushioned air cushion between the driver and the steering wheel. Can provide effective buffer protection for the driver. The traditional driver's airbag is arranged in the steering wheel, but such an arrangement takes up a lot of space in the steering wheel, which adversely affects the freedom of shape of the steering wheel. With the development of intelligent, networked, electrified, and shared cars, the steering wheel will integrate functional electronic functions, and the steering wheel needs more space for other functional components. In addition, with the development of intelligent driving, in the automatic driving scene, the driver's seat may be adjusted to a half-lying or fully lying position, or the seat may be rotated to other angles. In suc...
