    Background and Summary of the Invention
    [001] The present invention claims priority from provisional application US 61/508,726 filed on July 18, 2011. The present invention generally relates to occupant safety systems for aircraft and more particularly to restraint systems for occupant seated in seats that are facing the center of the aircraft.
    [002] The present invention includes a restraint system to protect at least one occupant of the aircraft, the aircraft including a cabin provided with at least one seat facing the center of the aircraft or seats generally facing in a direction generally perpendicular to the line longitudinal center of the aircraft; the restraint system includes a first airbag inflatable from a stored position to an inflated position, the airbag when inflated is located adjacent to the seated occupant and is located on a forward-facing side of the occupant of the aircraft, the airbag reducing the movement of the occupant to the front of the aircraft and cushions the occupant against an impact with the structure of the adjacent aircraft, such as a wall or bulkhead, and with another occupant who is seated adjacently.

    [009] Figures 5, 5A, 5B and 5C show additional embodiments of the invention.
    [010] Figures 6, 6A and 6B show another embodiment of the invention. Detailed Description Of The Drawings
    [011] Figure 1 shows a seating arrangement for a typical aircraft 50 such as a private jet. The seating arrangement includes a plurality of seats 52 arranged in the normal front-rear seating configuration. The aircraft 50 includes a plurality of centre-facing seats identified by numerals 54, 56 and 58, each of which respectively can seat, for example: one, two or three passengers. The centerline or central axis of the aircraft is shown by the number 60. The aircraft includes a number of bulkheads 62 and walls 64. As illustrated, the bulkheads may be on one or both sides of the seats facing the center.
    [012] Reference is briefly made to Figure 2 which shows an aircraft seat facing the existing center 56 occupied by two occupants 102 and 102 a. Each occupant is secured by a two-point seat belt system 120 used on the aircraft for many years which comprises two lengths of woven belt as a seat belt 122 and 122a, one end of which is secured to the aircraft seat or floor. . At the other end of a belt 122 is a tongue 124 which is insertable and lockable with a buckle 126 located at the other end of the belt 122a. Such tongues and buckles are known in the art. The deceleration vector of an aircraft landing or involved in a head-on accident is shown by arrow 130 and the acceleration vector of the aircraft taking off is shown by arrow 132.
    [013] In landing, accident, or take-off scenarios the occupant will initially move opposite the appropriate vector direction, even if the seat belt is buckled. The occupant swivels around on their rear and can slide into the seat in the vector direction. Also, when the vehicle lands and if the aircraft brakes are force applied, the occupant will initially move in the direction of arrow 130. On certain landings or take-offs where the level of acceleration or deceleration is high, seated occupants may hit a bulkhead 62 or other structure such as a wall 64, see Figure 1, appropriately positioned adjacent to the occupant. Occupant 102a seated rearward facing a first occupant 102 may collide with the body or head of the first occupant 102, injuring both. Injury to the bottom of the loss can also occur due to the flailing movement of the legs or the legs making contact with hard surfaces or other occupants. After the initial collision with the bulkhead the occupant may ricochet, see arrow 134, and collide with the adjacent occupant or other part of the aircraft. Considering the possibility of injury, aircraft occupants are discouraged from sitting in divan-style seats during takeoff or landing. Practically speaking, discouraging occupants from sitting in center-facing seats reduces the aircraft passenger's carrying capacity. The above problems are solved by the present invention.
    [014] The potential for injury from sitting in the center-facing seat is reduced with the use of a 3-point seat belt system. A diagonal belt is diagrammatically illustrated by number 128 to illustrate a 3-point seat belt system. The use of a 3-point system reduces lateral movement of the body towards the shoulder over which the belt travels (as illustrated this would be towards the front of the vehicle), but not in the opposite direction towards another seated occupant. The issues related to this movement are also solved by the present invention.
    [015] Reference is made to Figure 3 which illustrates two occupants seated in a center-facing seat 56 as a divan; Figure 3 is basically the same as Figure 2. With reference to the seat back 57 of the seat 56 can be seen a plurality of frangible or operable doors 150, 150a and 150b configured to be positioned close to the shoulder of a seated occupant. typical size. Figure 3A shows the detail of the door 150 which is embedded in the seat back upholstery 57; the port150 has a vertically running tear line 152 that allows each half 151 of port 150 to open on inflation of an airbag. A door with a tear line can be replaced with one that hinges around a hinge or other similar solution. Located in the seat back 57 is a housing 160, located in a cavity in the seat back, in which an airbag inflator 161 and an actuable airbag 162 are placed. Inflators and airbags are also known in the art.
    [016] The airbag 162 can take many different shapes. Although not illustrated in detail, but is common knowledge, the inflator 161 includes an igniter 163 that ignites on receipt of a control signal from the controller (computer, circuit, etc.) 166. At igniter ignition the inflation gas is supplied to airbag 162 and/or supplies it. As seen in Figure 3A the airbag is initially stored in a compact configuration and upon receipt of the inflation gas it pushes against the door 150 opening it to reach a deployed condition as illustrated in Figure 3B. The stored airbag configuration may vary with folded, rolled, or other similar configurations. Referring to Figure 3B, airbag 162 is located between first occupant 102 and a typical bulkhead or wall 62. Another airbag 162a is located between occupant 102 and occupant 102a at the location of door 150a. Depending on the configuration of the aircraft it may be beneficial to include a third actuable airbag 162b (and inflator and port) on the other side of occupant 102a. The airbag 162 reduces the impact between the upper torso and head of the occupant 102 with the bulkhead. The airbag 162a between the occupants minimizes any interaction between the two adjacent occupants. Airbag 162b on the other side of occupant 102a may be useful if occupant 102a moves to the rear of the aircraft. Airbag sizes 160, 160a, and 160b are shown for illustrative purposes, actual sizes may vary by application.
    [017] Reference is briefly made to Figure 4 which illustrates two occupants 102 and 102a seated in a side-facing seat such as 56 or 58. This embodiment is illustrative of a 3-point restraint system 120a that uses a lap belt like this as a diagonal belt 122 a. As can be seen, additional passengers will sit in longer side-facing seats; similarly only a single occupant would sit in a narrow seat like 54, see Figure 1. The airbag configuration shown here is applicable to each seating configuration 54, 56 and 58. In Figure 4 an airbag fitted to seat 162, its housing , the actuating port and the inflator have been removed. In this embodiment, the airbag housing 160 is fitted into a cavity in the adjacent bulkhead 62 and the actuable port 150 is mounted proximate the surface of the bulkhead 62. The inflator 161 and airbag 162c are initially fitted into housing 160 on the bulkhead. In this configuration, the airbag 162c deploys axially from the bulkhead toward the occupant/passenger 102. Alternatively, the airbag module can be surface mounted on the bulkhead.
    [018] Figure 5 shows an alternative embodiment of the present invention. In this modality, the housing, the inflator and the airbag are positioned on the aircraft's superstructure, generally above the passenger's seated position. In Figure 5, a typical three-point seat belt restraint system is used comprising a buckle 201 and tongue 203 of known variety. In this configuration, the seat belt 205 comprises a diagonal belt part 207 and an abdominal belt part 209. The seat belt 205 passes through an opening in the tongue 203. If required, a known type of seat belt retractor can be associated diagonal belt and/or lap belt. The buckle/tab configuration shown is for the purpose of illustration; various combinations as shown in the technique can be used. In essence, each airbag 162d, 162e, and 162f is deployed from the aircraft's roof 200 and is sized and positioned so that upon inflation it is adjacent to the passenger's head and/or upper torso. Each of the above airbags is diagrammatically shown with a phantom portion 164 to indicate that the airbag length can be provided to protect the passenger's head and/or torso. Reference is briefly made to Figure 5A which illustrates an alternative airbag configuration. As illustrated, the airbags 162d through 162f can extend from the occupant's head to the pelvic region or to the seat cushion. Based on the various airbag configurations illustrated above, the various airbags 162 through 162f can be sized to protect the head, head and shoulder, head-shoulder-torso and head to the occupant's pelvic region or any combination thereof. Figure 5A shows a further variation of the invention in which the seat 54 (56) may include an armrest 210 with an airbag 212 that deploys upward from the armrest 200. Additionally, this airbag 212 can be used independently of any other airbags and can be sized to extend from the pelvic region to the occupant's head region. Occupant protection can be achieved by using a combination of an deployable airbag from or near the armrest in combination with another deployable airbag from a location near the occupant's head.
    [019] Figure 5B shows an additional embodiment of the invention. As previously described, during a head-on accident occupants in the divan seating position (side-facing) will tend to move towards the front of the vehicle, such movement of the occupant's head to the pelvic region is slowed down by the various airbags described above. Additionally, as can be seen from the various Figures, the lower parts of the occupant's legs are not limited, which is typical of this type of seating position. On many aircraft, the bulkhead does not extend to the ground in the occupant's lower leg area. The legs of the occupant seated near the bulkhead may also tend to move towards the front of the vehicle as illustrated by arrow 220, this movement may also tend to rotate the occupant's tibia as illustrated by arrow 221. This movement is impeded and/or significantly reduced with the use of a 230 leg bag that can be located in multiple seat positions. The leg bag 230, like any of the bags described above, would be actuated from a housing, through a protective port, and would be inflated by an inflator. With respect to the leg bag 230, the bag, housing, door and inflator can be located in any convenient position, for example, in the upright position of the seat close to the occupant's leg. Air pocket 222 is located so that when actuated it provides a barrier near the bottom of the bulkhead. Figure 5B also shows an additional mode in which the airbag 224 is deployed from the region close to the seat cushion. Figure 5B shows the location of additional airbags 222 for large divans.
    [020] Figure 5C shows an additional modality of the leg protection mechanism. In this modality, the forward movement of the leg and the rotational movement of the tibia are protected by a piston 240 which is actuated from a stored position to a position of protecting the occupant during a frontal accident. As illustrated in Figure 6, the piston 240 is part of the piston assembly 242 which comprises a housing 244, the piston 240 and the optional port. Actuation door 246 can be used to close an opening in the seat cushion upholstery and the door is moved to the side by the actuation piston. Actuation door 246 is configured to move away from the occupant's legs. Figure 6 does not illustrate a means of moving the piston out. In Figure 6A, a manually adjustable piston is shown. In this configuration, the occupant or attendant/stewardess would open actuation door 246, if used, grasp piston 240, for example, by engaging a finger recess 250 and pull the piston to its actuated, locked condition at which point the piston will be locked in place by a mechanism 251. The piston 240 can be re-stored in the housing 244 by releasing a manual lock 252 which disengages the mechanism 251. The unnumbered arrows which are part of Figure 6A and read Actuator and Retract shows the forward and retracted action of the piston 240. In Figure 6B, the piston 240 can be moved out quickly when actuating various actuators such as an electric solenoid or a gas-producing inflator. The piston can be designed to become locked in its actuated position using a locking mechanism such as 251 or, alternatively, the piston retract movement can be controlled by a return spring. For example, the piston would be held in its actuated position as long as the solenoid is active, as long as there is enough gas pressure to hold the piston in place, consequently the return spring moves the piston into the housing. In the alternative mode, the piston and its housing can be located on the underside of the seat cushion.
    [021] Many changes in the described modalities of the invention can logically be performed without departing from its scope. As such, this scope is intended to be limited only by the scope of the appended claims.
