Abstract
Abstract The invention is an improvement in inflatable air cushion systems for use as devices to protect passengers in vehicles. Pressure is transferred from an elongated gas container through a nozzle to an inflatable bag or envelope for inflating it. Openings are formed for transferring gas from the container through the nozzle by means of an explosive charge. The improvements of the herein invention reside in that the gas container and transfer means or nozzle are fabricated as separate parts. Spaced openings are provided in the nozzle along its length with solid portions or ribs between the openings. These openings are in the nozzle rather than in part of the elongated tank. The elongated tank and the nozzle are formed as extrusions. These parts are joined together by way of tongue and groove joints that form a strong joint preventing failure of the tank resulting from pressure.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
85 words
In a safety device for human protection comprising an envelope inflatable with a gas whereby to form a resilient cushion and having an elongated container under pressure, with means to provide elongated passageway means along the length of the container for transferring gas from the container to the envelope for inflating it, the improvement comprising the said container and the transfer means having parts forming a dovetail type tongue and groove joint securing the container and transfer means together along the length of the container.
Claim 2
Dependent Claim
85 words
In a safety device for human protection comprising an envelope inflatable with a gas whereby to form a resilient cushion and having an elongated container under pressure, with means to provide elongated passageway means along the length of the container for transferring gas from the container to the envelope for inflating it, the improvement comprising the said container and the transfer means having parts forming a dovetail type tongue and groove joint securing the container and transfer means together along the length of the container.
Claim 3
Dependent Claim
29 words
A device as in claim 1, wherein said parts are constructed to make it possible to join the parts by relative longitudinal movement along the length of the joint.
Claim 4
Dependent Claim
17 words
A device as in claim 1, wherein the parts forming the tongue and groove joint are extrusions.
Claim 5
Dependent Claim
18 words
A device as in claim 1, wherein interfitting tongues and grooves are formed on both of the parts.
Claim 6
Dependent Claim
28 words
A device as in claim 1, wherein said transfer means comprises a nozzle having a plurality of openings communicating with the container with solid portions between the openings.
Claim 7
Dependent Claim
35 words
A device as in claim 5, wherein said container has a diaphragm portion adapted to be ruptured by an explosive charge positioned to provide a gas release channel communicating with said openings in the nozzle.
Claim 8
Dependent Claim
50 words
A device as in claim 6, wherein said inflatable envelope has portions secured to the periphery of the nozzle, the nozzle periphery having a groove therein and spring retainer means engageable in the groove whereby to secure edge portions of the envelope between the spring retainer means and the nozzle.
Claim 9
Dependent Claim
37 words
A device as in claim 1, whereby said tongue and groove joint comprises tongues and grooves formed on the container and tongues and grooves formed on the transfer means, the tongues and grooves having mutually interfitting engagement.
Claim 10
Dependent Claim
38 words
A device as in claim 1, wherein the tongue and groove joint comprises interfitting tongues and grooves configurated to provide interfitting relationship whereby to prevent spreading of the parts of the container at the area of the joint.
