Abstract
Abstract To prevent rebound of a driver from an inflated air bag in a motor vehicle at the time of a collision, a valve or escape device is coupled to the air bag to permit expulsion of air from the bag as the driver is thrust against the bag. The valve may be connected to an air chamber through which the bag is inflated by a gas generating apparatus, and the valve is subjected to operation by an actuation which acts to open the valve when the air bag presses against the actuator upon impact of the driver with the air bag. The valve may also be formed by a thin portion of the air bag which is pressed against a cutter when the driver impacts against the air bag whereby the bag is cut and the air can escape.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
For a shock absorbing air bag apparatus in a motorcar in which an air bag is arranged to rapidly inflate in front of a driver upon collision of the motorcar: a controlled escape mechanism coupled to the air bag and normally closed, and means to open the escape mechanism when the driver is forced into contact with the air bag and the air bag has undergone a predetermined deformation as a result thereof, said escape mechanism comprising a displaceable valve member which when opened releases air from the bag, said means to open the escape mechanism comprising an actuator for said valve member, said actuator being located in spaced relation behind the air bag so as to be activated by contact with the bag when the bag is inflated and has been deformed by contact of the driver.
Claim 2
Dependent Claim
138 words
For a shock absorbing air bag apparatus in a motorcar in which an air bag is arranged to rapidly inflate in front of a driver upon collision of the motorcar: a controlled escape mechanism coupled to the air bag and normally closed, and means to open the escape mechanism when the driver is forced into contact with the air bag and the air bag has undergone a predetermined deformation as a result thereof, said escape mechanism comprising a displaceable valve member which when opened releases air from the bag, said means to open the escape mechanism comprising an actuator for said valve member, said actuator being located in spaced relation behind the air bag so as to be activated by contact with the bag when the bag is inflated and has been deformed by contact of the driver.
Claim 3
Dependent Claim
23 words
The combination as claimed in claim 1 comprising an elastic means acting on said valve to urge the valve member to closed position.
Claim 4
Dependent Claim
51 words
The combination as claimed in claim 3 wherein the motorcar has a body defining an air chamber which is connected to a gas generating apparatus, the air bag being connected to the chamber, said valve member being separate from said air bag and mounted on said body at said air chamber.
Claim 5
Dependent Claim
15 words
The combination as claimed in claim 3 wherein said valve member and actuator are integral.
Claim 6
Dependent Claim
54 words
The combination as claimed in claim 1 wherein said valve member is constituted by a portion of the bag of reduced thickness, said actuator comprising a fixed cutter positioned adjacent said portion of the bag of reduced thickness to cut the same when the bag is inflated and deformed by contact of the driver.
Claim 7
Dependent Claim
25 words
The combination as claimed in claim 5 wherein said portion of reduced thickness of the bag is constituted by a restricted region facing said cutter.
