Abstract
A gas bag safety apparatus comprises an inflatable torso bag installed within the compartment of a vehicle, a gas-diffuser assembled within the torso bag and having a number of jet holes to supply pressurized gas fluid into the torso bag from an external gas pressure source, and an inflatable knee bag housed within the torso bag and mounted on a portion of the diffuser through a check valve to be inflated by the pressurized gas fluid supplied from the diffuser, the check valve being provided on the opening end of the knee bag to be opened into the knee bag. The valve seat portion of the check valve is at least double-layered to reinforce a portion of the knee bag exposed to the jet holes.
