Problems solved by technology

The disadvantage of the traditional symmetrical design is that the airbag exerts a large squeezing force on the driver's chest at the six o'clock direction of the steering wheel, which may cause a large amount of compression damage to the driver's chest

Abstract

The invention provides an asymmetric air bag restraint system, an air bag restraint system assembly and a vehicle, and relates to the technical field of vehicles. The asymmetric air bag restraint system comprises an air bag and an air generator. The air bag comprises a front piece with a round periphery and a back piece with a round periphery, the front piece and the back piece are overlapped and sewn at the boundary to form a sealed bag body, the front piece faces a driver, and the back piece backs onto the driver. The air generator is used for supplying air to the air bag so that the air bag can be expanded to the unfolded state from the folded state. The back piece is provided with an air generator installation hole used for installing the air generator, and the center of the air generator installation hole does not coincide with the center of the air bag. The air bag restraint system assembly comprises the asymmetric air bag restraint system and an air bag box, and the asymmetric air bag restraint system is arranged in the air bag box in a folded mode. The vehicle comprises the air bag restraint system assembly. The air generator is installed in the air bag in an eccentric mode, so that pressing force to the chest of the driver is reduced after the air bag is unfolded while the protective function for the head of the driver by the air bag is not lowered.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an asymmetric safety airbag, a safety airbag assembly and a vehicle. Background technique [0002] Vehicle safety is directly related to human life and health, and is one of the most important performance indicators of vehicle products. The driver's head and chest are fatal parts, so they are the focus of vehicle collision safety protection. In national regulations related to vehicle safety and various new car evaluation procedures (such as China's C-NCAP), the driver's chest compression injury value has always been the focus and difficulty of vehicle passive safety performance optimization. [0003] When the vehicle has a relatively violent frontal collision, the driver's airbag device assembled in the steering wheel is inflated by the gas generator to expand the airbag, which has a good buffering and protection effect on the front driver of the vehicle. However, the gas gene...
