Abstract
An improved air bag system requires low manufacturing cost and facilitates an installation thereof. A flexible hose is installed between an air bag and an inflator for preliminarily charging air into the air bag, an air pipe is provided for connecting the flexible hose to an inlet manifold of a motor vehicle, a pressure sensor is installed within the flexible hose, and a cut off valve is within the air pipe. A compressor and an air reservoir are provided between flexible hose and the inlet manifold for supplying the air to the air bag through flexible hose and the air pipe. The inflator has a single filter in place of a cooling passage. A collision sensor, an electronic control unit and the inflator constitute a single module except the air bag to easily mount the air bag system to the motor vehicle. Thus, the quantities of a pyrotechnic material and a gas generating material required for inflating the air bag are reduced and the air bag of various sizes is employed while affording a cooling effect to an inflation gas of high temperature and high pressure.
