Title: Inflatable device
Inventor: SELWA MICHAEL STANLEY
IPC: B60R21/264
Filed: 1970-05-18
Abstract: 1,255,457. Inflatable bags. CHRYSLER CORP. 18 May, 1970, No. 23896/70. Heading B7B. [Also in Division F1] An inflatable device for use in vehicles comprises an inflatable bag 5 connected to a gas generator 7 having gas generating material confined in pockets which are adapted to release gas into the bag when the pockets are sequentially ignited to inflate the bag in a plurality of stages. In the particular embodiment the pockets contain gas generating material in the form of a propellant 35 composed of a mixture of potassium nitrate, charcoal, and sulphur and are covered by a diaphragm 40 which may comprise aluminium foil. The pockets comprise groups 11, 13 containing a primary ignition pocket 15 connected by grooves 17 to secondary ignition pockets 9 and each group of pockets is connected to other groups by grooves 19. Electrical ignition devices 25, 27 have a filament 33 across electrodes 29, 31 and extend into the primary ignition pockets 15. The filaments 33 and/or the electrodes 29, 31 are coated with an ignition material of potassium chlorate and zirconium for ignition of the propellant after current is passed through the filament. The plate 41 holds the diaphragm against the upper surface of the generator body 7 and has apertures aligned with the pockets. The bag 5 is preferably formed of a combined woven and rubber sheet material. The powder is ignited in the primary ignition pocket 15 to produce a pressure sufficient to rupture the diaphragm 40 over the area of that pocket and unburnt powder is propelled into the bag and continues to burn. The bag is thus thrown into a partially expanded position. Subsequent ignition of the secondary pockets 9 and rupture of respective parts of the diaphragm causes the bag to be fully inflated and the powder thrown into the bag continues to burn to prevent deflation.
