Apparatus for controlling smart airbag system using dual chamber structure

摘要

An apparatus for controlling a smart airbag system using a dual chamber structure may include a gas generator to eject hot gas at the time of a car crash, a gas chamber which receives the hot gas ejected from the gas generator and transfers the hot gas into an airbag, and a fluid chamber which cools the hot gas by spraying stored fluid, before it is introduced into the airbag.

1. An apparatus for controlling a smart airbag system using a dual chamber structure, the apparatus comprising:
a gas generator which ejects hot gas when a crash occurs; a gas chamber which is supplied with the hot gas ejected from the gas generator and transfers the supplied gas into an airbag; a fluid chamber which cools the hot gas by spraying stored fluid before the hot gas is introduced into the airbag; a piston which is installed in the chamber and compresses the fluid using the hot gas; a safety bursting disk which is burst by being pressed by the piston so that the fluid is sprayed and the hot gas is cooled; a gas hole size adjusting unit which changes a size of a gas hole which is a factor to determine an amount of the cooled gas injected into the airbag; and a controller which controls operation of the gas generator or the gas hole size adjusting unit according to an inflation force for the airbag, which is calculated using occupant information generated by a sensor.
