Process for inflating a gas cushion and safety system of the air bag type
First Claim
1. Method for rapid inflation of at least one gas cushion in an air bag safety system, comprising the steps ofstoring in reservoirs at least two pressurized gases shielded from each other and from the outside with a rupture seal common to at least two reservoirs;
- releasing, upon need, the filling gases from their reservoirs;
combining the filling gases essentially outside their reservoirs;
inflating the gas cushion with the filling gas.

Abstract
The invention related to a process for quickly inflating a gas cushion in a safety system of the air bag type in which at least two pressurized filling gases are stored being shielded from each other. Instead of the filling gases, initially only the starting material(s) of one or both filling gases can be stored. In case of need, for instance upon a crash-characteristic signal, the filling gases are released from their reservoirs; if necessary, the starting material(s) of one or more filling gases is/are first ignited due to the crash-characteristic signal and then produce(s) the filling gas. The released filling gases are then concentrated and finally inflate the gas cushion or air bag.

10. A safety system with a gas cushion of the air bag type which can be inflated rapidly comprising:
-
a. at least two pressure reservoirs storing each pressurized filling gas; b. gas outlets which can be burst for releasing and combining the filling gases in a chamber located outside the pressure reservoirs inflating the gas cushion, wherein the c. gas outlets of at least two pressure reservoirs are sealed by a common rupture seal. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
