`INFLATABLE RESTRAINT APPARATUS
`
`BACKGROUND OF THE INVENTION
`
`This invention relates to inflatable restraint appara-
`tus, and more particularly to inflatable restraint devices
`for use in automotive vehicles for restraining move-
`ment of an occupant or occupants in the vehicle during
`an accident.
`Inflatable restraint devices for restraining the move-
`ment of a vehicle occupant in the event of an accident
`are well known. These devices are adapted to be de-
`ployed and inflated when the vehicle is involved in an
`accident, the deployed and inflated devices providing
`a cushioning andrestraint for the occupants of the ve-
`hicle. Most of these deployable inflatable restraints are
`stored in the area of the instrument panel in front of the
`occupant. Some are deployed from below the instru-
`ment panel to engage the occupant’s knees and others
`are deployed from the headliner area of the vehicle
`down in front of the torso of the occupant for restrain-
`ing the same against forward movement. Oneofthe big
`concerns regarding the foregoing types of restraint sys-
`tems is their ability to restrain the occupantssatisfacto-
`rily under various impact conditions, such as frontal
`collisions,
`lateral collisions and roll-over conditions.
`The present invention relates to inflatable devices of
`the type which are deployed from the roof of the vehi-
`cle and are directed to restraining the occupants under
`various accidentsituations.
`
`BRIEF SUMMARY OF THE INVENTION
`
`Briefly, this invention comprises inflatable restraint
`apparatus having a torso restraining bag section con-
`nected to the roof and to a source of gas by one or more
`tubes or other inflatable elements, and also having a
`side curtain portion inhibiting an occupant’s egress
`from the vehicle through a door or side window.
`One of the primary objects of this invention is to pro-
`vide an inflatable restraint device which provides occu-
`pant restraint under frontal and lateral collisions, as
`well as under roll-over conditions, thus providing pro-
`tection under all impact modes.
`Another object of this invention is to provide a re-
`straint system which keeps an occupant’s head from
`going through a side windowor side window opening,
`and from engaging a side roof rail of the vehicle.
`A further object of this invention is to provide a re-
`straint system of the type described which tendsto hold
`the occupants down against the seat portion of the seat
`as well as against the back portion of the seat.
`Still another object of this invention is to provide a
`restraint apparatus such as described which provides
`protection agaist occupant head to A-pillar impacts.
`A further object of this invention is to provide a re-
`straint device of the class described which is adapted to
`provide cushioning and containment of the occupants
`during side impacts.
`A further object of this invention is to provide a re-
`straint device of the type described adapted to relieve
`the pressure inside the restraint when it tends to rise
`above a predetermined value,
`thereby reducing re-
`bound velocity.
`Another object of this invention is to provide a re-
`straint device of the class described which is aestheti-
`cally pleasing and is adapted to be deployed from the
`roof of the vehicle.

`Anotherobject of this invention is to provide an in-
`flatable restraint device of the type described which
`does not necessarily restrict the vision of the occupant
`even thoughthe device is deployed from the roofof the
`vehicle.
`A further object of this invention is to provide an in-
`flatable restraint device of the type described which is
`adaptedto collapse a certain amount if the occupant's
`head engages therewith during an accident, while at the
`same time providing restraint for the head as well as for
`the torso.
`Anotherobject ofthis invention is to provide an in-
`flatable restraint device of the class described which is
`adapted to positionitself between the instrument panel
`and a passengersitting in a conventional upright posi-
`tion and provide cushioning for forward impacts.
`A further object of this invention is to provide an in-
`flatable restraint device such as described which is op-
`erable to restrain an out-of-position occupant, i.e.,
`if
`the occupant is in a forward position, for example, the
`restraint is adapted to be deployed in such a manner
`that the passenger is held against the instrument panel
`during the accident.
`A further object of this invention is to provide an in-
`flatable restraint device of the type described wherein
`the side curtain and torso portions of the inflatable re-
`straint device may be coupled together to facilitate de-
`ployment.
`A further object of this invention is to provide locater
`means whichplace the torso bag in the appropriate po-
`sition and also provide an accommodation for locating
`the bag even though the seat of the vehicle may be in
`various forwardly and rearwardly positions.
`Another object of this invention is to provide an in-
`flatable restraint device of the class described which is
`simple and economical in construction, yet effective in
`Operation.
`Other objects and advantages ofthis invention will be
`made apparent as the description progresses.

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`Referring now to the drawings, and in particular
`FIGS. 1, 2 and 3, the numeral 1 generally denotes a ve-
`hicle having a body 3 which includes a roof 5, a front
`window 7 and a floor 9. Longitudinally extending rails
`11 are provided at the edges of the roof 5, with a front
`rail 13 extending between the front ends of the side
`rails above window 7. An instrument panel 15 is also
`provided at the forward end of a passenger compart-
`ment 17 formed by the roof, front window, floor and
`side windows 19.
`
`As shown, the passenger compartment 17 includes an
`occupant seat 21 having an upright back portion 23
`and seating portion 25. Occupants 27, 29 and 31 are
`shown seated in seat 21.
`The apparatus of this invention includes at least one
`gas source 33 for supplying gas to the inflatable re-
`straints. The gas source may be of various types, such
`as the gas generating types, or the gas storage or reser-
`voir type. As shown, a reservoir type 35 is shown lo-
`cated rearwardly of the passenger compartment. The
`reservoir 35 is connected by a collapsible flexible tube
`or conduit 37 extending along the roof to a housing
`area 39 located in the roof over the front seat area.
`Tube 37 is connected to an inflatable side curtain 41
`and to an inflatable torso restraining bag 43. A Y-
`shaped section 45 and tube 47 connect tube 37 to an-
`other portion of torso bag 43. More specifically, tube
`37 extends into an inturned sleeve 49 of the side cur-
`tain 41. The tube '37 includes a plurality of openings $1
`through which the gas may pass. The side curtain 41 is
`normally maintained in a folded condition in the hous-
`ing area 39, but when filled with gas is adapted to ex-
`tend across the side window 19 and inhibit movement
`of the passenger therethrough or against the roofrail.
`The side curtain 41 is maintained in a generallyflat
`condition upon inflation by means of a plurality of re-
`straining webs 53 spaced apart from one another in a
`longitudinal direction of the vehicle. The side curtain,
`in between the webs 53, tends to assume a cylindrical
`configuration, but the over-all generally flat configura-
`tion is maintained. Each web has an elongated notch or
`recess 55 at the upper and lower ends thereoffor per-
`mitting such-upper and lower ends to expand outwardly
`into a larger volumetric space as shown in FIG. 10. This
`enlarged upper section provides additional cushioning
`between the occupant’s head and the roof rail. More-
`over, the strain on the connection between the ends of
`the webs and the curtain walls, whether adhesive or
`sewing or any otlier type, is lessened because of the use
`of the notches.
`The forward end of the tube 37 extends into an in-
`turned sleeve 57 which, as shown, is joined by a con-
`nector 59 to one of two filler tubes 61 and 63 for torso
`bag 43. Filler tube 61 is a flexible fabric or the like tube
`whichis normally folded, along with bag 43, and stored
`in storage area 39. More specifically, the tube 61 in-
`cludes a spring biased blow-off or relief valve shown di-
`agrammatically at 65 for permitting gas to escapeif the
`pressure in the tube exceeds a predetermined amount.
`
`4
`Tube 61 also has a ring portion 67 folded or rolled back
`upon itself as shown at 69 in FIG. 6 which, as made ap-
`parent hereinafter, provides an expansible section to
`permit head penetration. A cover tear-awaystrip 71
`having perforation 73 therearound is adapted to rip to
`permit unfolding of folded ring portion 67. Tube 61 is
`adapted, when inflated, to extend from the roof down
`to the torso bag, and will function as a strut or brace for
`holding the torso bag against the occupants’ laps. Tube
`63 is of the same construction as tube 61 and is con-
`nected to the Y-shaped section 45 by tube 47.
`The side curtain 41 is connected to the torso bag 43
`by two straps 75 and 77 in a manner which effects
`proper deployment andpositioning of the curtain rela-
`tive to the torso bag. It will be understood that the con-
`nection between the side curtain and the torso bag,
`both at the passage means for the gas and at the point
`at which the straps 75 and 77 are located could be dif-
`ferent than shown. For example, the side curtain and
`torso bag could be formedintegrally with one or more
`openings at the forward end of the curtain providing
`the gas passages and the bags could be integrally sewn
`or formed together adjacent the bottom of the curtain.
`The torso bag 43 maybe provided with two inflatable
`positioning stubs or locaters 79 and 81 extending for-
`wardly from the torso bag 43. These stubs cause the
`torso bag 43 to push the bag toward and into engage-
`ment with the torso of the occupant.
`Driver protection is provided by a driver bag 83
`adapted to be stored in a housing area 85 in roof 5. A
`filler tube 87 generally similar to tubes 61 and 63 con-
`nects the driver bag to the supply of gas. As shown, a
`gas generatoror storage bottle 89 is provided in the for-
`ward portion of the vehicle with a tube 91 extending up
`the A-pillar to the tube 87. A relief or blow-off valve
`65 is also provided in the tube 87 to permit the escape
`of gasif the pressure in the tube and bag exceeds a pre-
`determined amount. A branch tube 93 extends from
`tube 91 to a side curtain 95 generally similar in con-
`struction to said curtain 41. However, curtain 95 is
`shaped differently than curtain 41 as shown. While a
`separate gas source is shown for the driver bag 83 and
`side curtain 95, it will be understood that both bags 43
`and 83 and both of the side curtains could be con-
`nected to the same gas source.
`Assuming that occupantsare in the position shown in
`FIGS.
`1 and 2, operation and deployment of the appa-
`ratus is as follows:
`The gasfor inflating the torso bag 43 and side curtain
`41 is generated or supplied to the area of the housing
`or reservoir 35 and immediately is forced into the filler
`tube 61 and then through openings 51 into side curtain
`41. Gasis also supplied to tube 63 through tube 47. As
`the gasfills the filler tubes the bag 43 is thrown into the
`laps of the center and right side occupants to form a
`generally U-shaped restraint. Also, the curtain 41 is
`pulled down by meansof the connection straps 75 and
`77. As the gas continues to flow throughthefiller tubes
`61 and 63 into the bag section 43 thelatter is filled and
`generally assumes the shape shown in FIGS. 1-3, with
`the stubs 79 and 81 engaging the instrument panel and
`forcing the bag against the torso of the occupants. The
`inflated tubes or struts and torso bag tend to keep the
`occupants engaged therebyin their seated position with
`their legs held against the seat portion. At the same
`time, the side curtain 33 is inflated into and pulled into
`its side position on the outside of the occupants andis

`

`inflated to provide a cushion. If either of the passengers
`moves forward and his head engages thefiller tube 61
`or 63, the perforations 73 in the cover 71 give away and
`permit the tube to unfold and expand in that area,
`thereby permitting the occupant’s head to move for-
`wardly to the position shown in FIG. 7. Accordingly, a
`resilient restraint is provided for the head. The stubs 79
`and 81 will probably collapse as the occupants move
`forward into engagement with the bag section 43. How-
`ever, aS noted previously, the purpose of the stubs is
`primarily to position the bag against the occupant’s
`torso during the initial deployment.
`It will be seen that the bag section 43, by coming
`down in front of the occupants, effectively prevents
`substantial forward movement of the occupants. If the
`accident had occured when an occupant werein a for-
`ward position, such as generally shown in FIG. 5, the
`torso bag, on being deployed, would engage the back
`of the occupant and form a brace between the back 23
`of seat 21 and the back of the occupant. Thus, the oc-
`cupant would be held in the forward position generally
`against the instrument panel. This position may be as
`desirable during an impact as having the bag section 43
`located between the torso and the instrument panel. In
`either event the passenger or occupant is restrained
`from substantial forward movementafter the bag is de-
`ployed.
`The driver bag 83 and side curtain 95 are also de-
`ployed simultaneously with the bag 43 by means ofthe
`tube 91 and gas source 89, The driver bag is adapted
`to be deployed into the space between the steering
`wheel and the driver’s torso as shown in FIGS. 1, 2 and
`4. The side curtain 95 extends downwardly between the
`driver and the door.
`In view of the foregoing it will be seen that theinflat-
`able restraint apparatus of this invention is adapted to
`be conveniently and aesthetically stowed in the vehicu-
`lar roof structure, thus avoiding the necessity of tearing
`up the instrument panel to provide storage space for
`the bag apparatus. Moreover, the torso bag 43 is thrust
`downwardly toward the laps of the occupants, if the lat-
`ter are in an upright position, and then arefilled to pro-
`vide the restraint for the occupants. The pusher stubs
`79 and 81 engage the instrument panel and force the
`inflated section toward the occupants. The stubs also
`provide an accommodation for various seat positions,
`i.e., if the seat is in a forward position the stubs obvi-
`ously do not become fully inflated and extended. How-
`ever, if the seat is in a rearwardly position the stubs will
`fully inflate and move the bag back into engagement
`with the occupants. If the occupants are in an out-of-
`upright position the bag 43still functions effectively to
`hold the occupants in a position against the instrument
`panel.
`It will also be understood that the bags and side cur-
`tain provide protection in frontal, lateral and roll-over
`conditions. Protection is provided to the occupant’s
`heads against engagement thereof with the A-pillar and
`with the side roofrails.
`In view of the foregoing it will be seen that the other
`objects and advantages of this invention are achieved.
`Although only one embodiment of the invention has
`been disclosed and described, it is apparent that other
`embodiments and modifications of the invention are
`possible.
