Abstract

Abstract An improved vehicle safety device is disclosed which is adapted to protect a vehicle occupant or a pedestrian from injury in the event of a collision of a motor vehicle. The safety device includes an inflatable confinement or a protector bag which is arranged to be rapidly expanded to a protective position immediately when the motor vehicle encounters the collision. The inflatable confinement is expanded with a pressurized gas which is supplied from a pressurized gas generator which is normally closed by a rupturable sealing member. The sealing member is ruptured to open the gas generator by means of a mechanism including an explosive means and a rupturing means which is moved by activation of the explosive means to a position in which the sealing member is ruptured.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 308 words
A vehicle safety device for protecting a vehicle occupant or a pedestrian from injury during a collision of a motor vehIcle, comprising an inflatable confinement having a collapsed stowed position and an expanded protective position, pressurized gas generating means storing a medium for producing a pressurized gas and having a pressurized gas discharge spout; a rupturable sealing member attached to a leading end of said discharge spout for closing the pressurized gas generator, a housing secured to said pressurized gas generating means for enclosing said discharge spout and said sealing member, said housing having a bore substantially aligned with said discharge spout and divided into inner and outer compartments by an apertured partition wall and having an opening communicating with said inflatable confinement, said housing having formed therein an aperture formed in the upper wall of said outer compartment, opposite said portion, said outer compartment being vented to the open air through said aperture, said inner compartment communicating with said opening; rupturing means movably accommodated in said bore, said rupturing means including a plunger portion connected at its inner end to said sealing member and extending outwardly into said outer compartment through said partition wall and an enlarged outer end portion merging from said plunger portion and movably positioned in said outer compartment; explosive means located between said partition wall and said enlarged outer end portion of said rupturable means, and impact responsive triggering means connected to said explosive means and actuated in response to an impact resulting from said collision to blast said explosive means for causing said rupturing means to be forcefully projected away from said sealing member to rupture the sealing member whereby said pressurized gas is admitted into said inflatable confinement from said pressurized gas generating means through said bore and said opening in said housing for inflating the confinement to said protective position.
