Portable motor vehicle safety airbag
First Claim
1. An airbag device for use in a vehicle having passenger seat belts therein, said device comprising a housing having a first guide member secured to said housing and a second guide member mounted so as to be movable with respect to said first guide member, said guide members being mounted to the housing in a cantilever configuration and said housing further comprising a recess sorted in the rear portion thereof and slots formed in the walls of said housing for receiving the side edge of a seatbelt passing from one of said slots, through an S-shaped path around said guide members to the other of said slots, said guide members being so mounted and positioned that the seat belt passing around both of said guide members is capable of exerting a force tending to relatively move said guide members in the event of a collision, said housing including a source of compressed gas and sensor means connected to said second guide member for detecting the relative movement of said guide members, an inflatable airbag adapted to receive gas from said source of compressed gas, whereby upon occurrence of a collision, said sensor means detects the collision and causes release of said compressed gas and inflation of said airbag.

Abstract
A portable airbag device for use in an automotive vehicle having passenger seat belts therein, the device comprising a housing having a projecting male buckle element and a female buckle receiving element for insertion between the two buckle elements of the seat belt system, or the housing being adapted to be attached to the seatbelt so that the seatbelt forms an S-shaped path for exerting tensile force against the elements forming the bends in the path, the housing also including a source of compressed gas and a sensor for detecting the occurrence of a collision, an inflatable airbag connected to the source of compressed gas, and a releasable fastener for securing the airbag to the passenger seat belt and positioning the airbag in front of a user, whereby upon occurrence of a collision, the sensor detects the collision and inflates the airbag.
