  • Lap belt right portion 16a is engaged in belt extension 24 which in turn is anchored in right floor anchor 14 in vehicle floor 13 and the left belt portion 16b is secured to the vehicle floor 13 by right floor anchor 15.
  • lap belt may have two sections and a buckle.
  • bag 18 with exterior inflatable cloth body 19 has a cloth passageway 21 between slot portals 21a, 21b through which lap belt 16 is passed.
  • Cloth body 19 together with cloth passageway 21 comprise the pressure-retaining envelope 18e of bag 18 into which envelope 18e the gases of inflation are introduced or formed.
  • Lap belt 16 is readily slidable back and forth through passageway 21 when bag 18 is deflated. Such movement provides for adjustment of bag 18 with respect to the occupant.
  • Bag 18 's gas inlet neck 22 (Fig. 7) can be connected to gas conduit 23 extending from a remote location such as the floor 13.
  • Gas conduit 23 is supplied gas from a storage gas container or a pyrotechnic gas inflator or a combination thereof, and alternately the inflation source may be contained within the bag 18.
  • FIG. 2 an alternative embodiment is shown in which folded bag 18 is covered by an elongated rupturable pouch 20. Bag 18 is shown folded for positioning in pouch 20 in a ready-to-deploy position with belt 16 loosely positioned for the comfort of the occupant.
  • This alternative system has a gas-generating inflator positioned in bag 18 or pouch 20.
  • Fig. 4 shows bag 18 with the alternate inflation entrance of gases from conduit 23 through neck 22.
  • Bag 18, as inflated is generally round in shape as viewed from above (Fig. 3) and generally triangular in shape as viewed from the side (Fig. 4) .
  • Bag 18 has a bottom seat surface and leg engaging surface 18a; a torso engaging surface 18b and front non-engaging surface 18c. Surfaces 18a and 18b intersect along occupant's waistline (WL) . Since belt 16 passes through bag passageway 21 which is distance (d) from the occupant's waistline (WL) , the inflation of bag portion 18r to the rear of belt 16 pushes occupant (0) back and down in his or her seat as bag 18 is first inflated (see Figs. 4 and 5) .
  • This action also removes any slack that may have existed in belt 16 due to looseness of wearing. Further, the inflation of the bag 18 and the creation of inflated bag space 18 also displaces bag over spaces 18h and 18i toward the occupant's chest and upper leg, respectively. Front bag portion 18f, the remaining portion of bag 18, is forward of the belt 16. Front bag portion 18f functions to support and resist rotation of occupant's (0) torso (T) as forces of vehicle deceleration act on torso (T) . Bag 18 may also include a set up reinforcing cloth panel 25 to strengthen bag 18 is the belt-engaging area which must withstand forces of inflation and occupant restraint as the vehicle decelerates.
  • bag 18 is accomplished sufficiently rapidly, using inflators of stored gas or pyrotechnic type or combinations thereof, so that the occupant's lap belt 16 is tightened by inflation of the rear bag portion 18r prior to forces of deceleration acting on the occupant's (0) torso (T) which force tends to move the torso (T) forward in rotational movement about belt 16. Only a few degrees of torso (T) rotation is permitted by the compression of bag 18. Any additional torso rotation will depend on the occupant's seated position and whether bag 18 rests on the occupant's legs, seat 12s or combination of both. Bag 18 is shown in Fig. 5 engaging seat 12s over area 12a as torso (T) is decelerated. Torso rotation is preferably less than 10° from the vertical. However, depending on the occupant's size and the size and shape of the bag, rotation of the torso may be up to 30°.
  • horizontal force (F) represents the force exerted by occupant's torso at a distance X from lap belt 16 creating a torque (T 1 ) .
  • torque (T,) bag 18 To resist torque (T,) bag 18 generates an equal and opposite torque (T 2 ) .
  • Torque (T 2 ) is force (F 2 ) times distance (Y) .
  • Fig. 10 is also a schematic showing the embodiment in which the belt passes through the bag with bag portion 18r inflating between the belt and the occupant.
  • Initial bag inflation causes the bag to push the occupant back of vertical line (V) 15° (note the 90° angle of Fig. 9 and the 105° angle of Fig. 10) .
  • Bag portion 18i pushes the occupant down in the seat and bag portion 18h pushes occupant back in his seat.
  • Bag 18 when inflated is restrained from forward movement by lap belt 16. Bag 18 rotates a few degrees as it is acted on the forces of the occupant's torso deceleration. Bag 18 is shaped and sized to prevent substantial torso rotation of any occupant including a large man. Smaller occupants will experience even less torso rotation. Bag 18 has a bag exterior surface 18a which engages a substantial area of occupant's legs and seat surface between the occupant's waist and knees. Bag 18 also has a surface 18b for engaging a substantial portion of torso from the waist to the head. Bag 18 may also be sized to support occupant's head. Preferably, bag surface 18a engages 1/3 to 2/3 of occupant's upper legs. Upper legs are the portion of the legs between the hips and knees. Bag surface 18a also engages the seat surface over the seat surface area between occupant's legs.
  • bag 18 in a further alternative embodiment shown in Fig. 6, bag 18 includes deployable blister 34. As occupant's (0) torso (T) exerts forces of compression on bag 18 increasing the gas pressure therein to a selected threshold allowing stitches 35 to rupture blister section 34 inflate to provide support for the occupant's (0) and head (H) .
  • uninflated bag 18 has bottom surface 31, passage outlet ends 21a, 21b and gas inlet 22.
  • Fig. 7 shows uninflated bag 18 with outside portions 28, 29 folded to positions adjacent central bag bottom portion 30 which central portion 30 is approximately the width of belt 16.
  • Fig. 11 illustrates a further embodiment of the present invention in which the inflatable member 36 which may be of any shape and configuration is foldably mounted on lap belt system 38 which system has positioned in it the entire inflation arrangement.
  • Tongue unit 39 is connected to a tongue belt section 41 which in turn is attached to tongue belt section anchor 43.
  • the belt system 38 also includes a buckle 45, a buckle belt section 46 and a buckle anchor 48.
  • Occupant (O) seated on seat 49 is restrained by belt system 38.
  • FIG. 12 an inflatable member in the form of bag 55 is shown which bag 55 has a particular shape including leg-engaging bag wings 56, 57 and a central blister section 59 which extends downwardly near to or against seat surface 51. Whether blister section 59 engages seat surface 51 depends on the extent to which occupant's legs are initially spread apart and the extent to which blister 59 of bag 55, as inflated, causes any further leg separation. Bag wings 56, 57 are positioned and shaped with widths d,, d 2 , respectively so that they properly serve both large and small occupants.
  • bag 55' consists of bag body 60 made of two stitched together bag panels 60a and 60b (not shown) which include two upper stitched bag body pockets 64, 65 formed by tucking bag body panel material into the interior of bag 55' and stitching such tucked-in panels to adjacent bag panels employing stitched generally-horizontal rows 67, 68 and 69. Bag body pockets 64, 65 are deployable under selected circumstances described below to increase the bag size and shape.
  • Fig. 14 deployment of bag 55 including its blister section 59 is shown (see also Fig. 12) .
  • the forward movement of occupant (O) is shown in dashed lines.
  • Figs. 15a-c there is shown the stages of deployment of body pockets 64, 65 during inflation of bag 55' when occupant-induced internal bag pressures reach predetermined levels.
  • the reason for pocket deployment is to increase the size and height of bag 55' to serve larger, taller and heavier occupants.
  • forces are exerted on the bag as it controls the occupant's movement including forward torso movement causing bag pressure to increase. If the occupant (0) is sufficiently larger and heavy, pressure will build up in bag 55 to cause stitch rows 67, 68 and 69 to sequentially break and to deploy the body pockets 64, 65 as bag additions. Stitching closer to the central portion of bag 55' will fail first.
  • Fig. 15c shows bag 55' with both pockets 64, 65 fully deployed. As bag size increases by pocket deployment bag pressure is reduced for a given amount of gas in the bag; however, the forces acting on the occupant may remain the same since the area over which the forces act has been increased.
  • Fig. 16a shows use of side pockets 61, 62 created by generally-vertical stitch rows 61a, 62a. Deployment of side pockets 61, 62 due to stitching failure are shown in Fig. 16b.
  • Fig. 16c illustrates bag 55" with a head protecting portion 63.
  • Stitching bag panels using any suitable patterns are contemplated by the present invention to provide additional inflatable member size during inflation and the creation of forces resulting from occupant restraint.
  • deployment of larger inflatable member volumes to accommodate larger occupants may be accomplished by fabricating inflatable members, such as bags, of expansible or stretchable material. Members made of fabrics or other materials which expand or stretch when inflated and when additional forces are applied by the occupant (0) during or after inflation are alternatively useful alone or in combination with non-stretchable materials.
