Abstract
A passenger restraint system for vehicles. A pouch containing an inflatable restraint bag is mounted to a seatbelt so that the pouch is positioned in front of a passanger when the belt is worn. There is an opening in the forward side of the pouch for permitting the bag to expand out of the pouch upon inflation. A flexible hose provides a conduit for supplying compressed air to the inflatable bag from a compressed air cylinder mounted to the vehicle body. A valve permits the air to flow from the cylinder through the hose to the bag in response to an impact received by the vehicle, so that the bag inflates and restrains the passenger against forward motion. The bag may be made of Kevlar.TM., or may be provided with Kevlar.TM. facings. The valve may be a lid positioned in the neck of the air bottle and held place by a pin and a hinge. The pin may be withdrawn by a solenoid actuated by a deceleration sensor so as to release the lid. Alternatively, an actuating member positioned in a bore may strike an end of the actuating member in response to the impact so as to move the actuating rod forward and out of the receptacle.
