Abstract

The invention relates to an airbag and an airbag assembly. The airbag comprises an airbag body, wherein the airbag body comprises first portions and second portions, and the outer sides of the first portions and the second portions are connected; when the airbag body is unfolded, the first portions are subjected to air inflation and expanded, and the second portions are not subjected to air inflation and extend in an unfolded region of the airbag body with the expansion of the first portions, wherein the unfolded region is used for providing protection for a passenger between the passenger anda vehicle; and when the airbag body is in a stored state, the first portions and the second portions are contained in a reserved space in the vehicle. According to the airbag, the great protection can be provided for the passenger, and meanwhile, the light weight is achieved.

Description

technical field [0001] The invention relates to an automobile safety device, in particular to a safety airbag and a safety airbag component. Background technique [0002] In vehicles, an airbag device is commonly used to protect occupants of the vehicle from damage in emergency situations. The airbag device includes an airbag and a gas generator. Airbags are generally stowed and deployed only when the vehicle is collided or impacted. When the vehicle collides or is impacted, the gas generated by the explosion of the gas generator will rapidly inflate the airbag in the stowed state, and the inflated airbag will inflate to provide protection for the occupants of the vehicle. Typically, the actual protective volume of an airbag that protects an occupant between the occupant and the vehicle is equal to the inflation volume of the airbag. Therefore, if the airbag is required to have a larger actual protection volume, the airbag needs a larger inflation volume, and accordingly,...
