Abstract
ABSTRACT
This product may be both an automobile factory or an after market installation item intended to replace the horizontal lap seat belt. In this invention, a nylon bag is incorporated into the lap belt to provide (when inflated) protection to an individual in the event of a collision.
This device is initiated by the "G" force exerted against the lap belt and activated by a series of mechanical actions to puncture a Co2 cylinder thusly providing a sufficient volume of gas to inflate an air bag or balloon.

This invention relates to mechanically operable device for inflating an air bag to provide protection to a vehicle passenger in the event of a collision.
It is common in automobiles for air bags to be installed in the steering wheel or dash board. They are activated by sensors mounted in various places on the frame of the vehicle. When these sensors are activated, they send an electrical charge to an explosive substance which provides the volume of gas to inflate an air bag. Air bags of this type are, however, dangerous in that an explosive substance is utilized which may cause further injury to the person. The common air bag when activated, is inflated at high speed toward the passenger. This in turn may cause further injury.
I have found that these disadvantages may be overcome by providing an inert gas to inflate the air bag and to reposition the air bag to intercede between the passenger and any object they may be propelled against.

Riley ~ i 0 ~1 a 2 CEOTechnical Coordinator In drawings which illustrate embodiments of the invention, Figure 1 is an overall view of the complete assembly. Figure 2 is an end view of Figure 3. Figure 3 is a top view partly in section of the belt lock, triggering mechanism. Figure 4 is a side view partly in s~ction of Figure 3. Figure 5 is a cross section view of the firing mechanism assembly.
The seatbelt air bag is activated or armed by inserting tang (10) into fPmale portion (1) of seatbelt lock (17). The tang (10) is held in place by spring (18) pressure against seatbelt tang lock (17). When sufficient "G" force or pressure is exerted on the spring loaded triggering device (23) (located in female portion of seatbelt lock (1)), the plate (23) exerts pressure on the helical tension springs (13) which allows the plate (23) to pull a cable (11). The cable (11) is encased in a plastic coated wire wrapped shield (2) or cover directly connected to the female portion of the seat belt lock (1) and the firing device as plate (23) is directly connected to the female portion of the seatbelt lock(1) and the outer casing of the firing mechanism (22). It allows the cable (11) to pivot latch (29), which in turn exerts pressure on the sear (28) of the firing mechanism. The sear pivots on its axis, releasing a sliding block (27). The sliding block (~7) moves forward under pressure exerted on it by spring assembly (26) and (25), engaging the firing pin extension (30). As the block (27) moves forward, the firing pin extension (30) enters a tapered groove in the block (27), camming the firing pin (31) backwards into the primer cap (35) of the Co2 cylinder (34) puncturing the cap (35).
As the block (27) moves forward, the firing pin extension passes under the tapered portion of the block (27) and into the grooved rear portion of the block (27). As there is not further rearward pressure exerted on the firing pin (31), it is forced forward from and out of the primer cap (35) of the Co2 cylinder (34) by the compressed Co2. This movement of the firing pin (31) reasserts itself into its original position. The compressed Co2 is explosively released into a teflon tube (33) which is directly attached to the air bag (6).

Riley CEOTechnical Coordinator 896-~819 896~451 As the Co2 travels through the tube (33), it warms and expands slightly before entering the nylon air bag (6). The air bag (6) is accordion-folded onto the cross lap portion of the sealtbelt (8).
It is held in the folded position by velcro strips attached to the back of the lap belt (8) and secured by stitching to the lap belt (8). As the Co2 enters the air bag (6), the bag (6) begins to inflate, forcing the velcro retainers apart. The air bag (6) is inflated by the Co2 to its full capacity. Once the Co2 is discharged into the air bag (6), the bag (6) slowly deflated, allowing further or partial protection from secondary collisions or flying debris which could cause injury.
