Wearable type airbag system

Abstract

The invention discloses a wearable type airbag system. A novel connection or installation method is adopted, particularly, under the support of a wireless sensor network WSN technology, an airbag assembly is worn on a body of a passenger, and some disadvantages that in a traditional scheme, an airbag assembly is fixedly installed in the middle of a steering wheel or in a central console are overcome. A airbag (10) is fixed to the front of the chest of the passenger, the unfolding direction is the same as the direction of movement of a human body, the recoil force can slow down the speed of forward rush of the human body, and even if the airbag (10) collides with the human body during the rapid expansion phase, the impact on the human body is further less than that of the case of opposite-direction collision. A chest cushion airbag (13) of the airbag system can reduce the impact on the chest of the human body, and can further be inflated to contract a seat belt. The airbag (10) is internally provided with a tubular inner container (19), and an included angle theta exists between the unfolded airbag and the human body to enable the head to move, the head of the passenger is prevented from being crush-injured in the unfolding process, and long-time suffocation and burning are avoided. The airbag assembly adopts a connection structure with convenient assembly and disassembly and position adjustment.

Description

technical field [0001] The invention provides an automobile safety air bag. Background technique [0002] Airbags are a common passive anti-collision measure for cars, but the front airbags can only be installed fixedly in the middle of the steering wheel or inside the center console. Hours, plus the speed at which the occupant keeps moving forward under the action of inertia, the relative speed between the airbag and the occupant will be higher. If the occupant collides with the airbag during the stage of rapid inflation, it may cause serious injury, and the timing of the collision is not entirely possible. In addition, when the occupant's body deviates from the installation position of the airbag, the protection effect is not good.

[0002] Airbags are a common passive anti-collision measure for cars, but the front airbags can only be installed fixedly in the middle of the steering wheel or inside the center console. Hours, plus the speed at which the occupant keeps moving forward under the action of inertia, the relative speed between the airbag and the occupant will be higher. If the occupant collides with the airbag during the stage of rapid inflation, it may cause serious injury, and the timing of the collision is not entirely possible. In addition, when the occupant's body deviates from the installation position of the airbag, the protection effect is not good. The sundries on the cover, the center console, and the decorations in the car may also be bounced by the airbag to the human body, causing additional damage. In addition, in the steering wheel The installation makes the structure of the connection complex, the manufacturing cost is high, and the installation and replacement are inconvenient
