[0058] It will be appreciated that terms such as front, back, top, bottom, side, short, long, up, down, aft, forward, inboard, outboard and below used herein are merely for ease of description and refer to the orientation of the components as shown in the figures. It should be understood that any orientation of the components described herein is within the scope of the present invention.

[0059] Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same, FIGS. 1-13 show a VTOL aircraft 10 and components therefor that include a number of inventive features.

[0060] FIGS. 1-5 include forward and aft doors 12 and 14 that open simultaneously and are positioned in a side opening 11 of the aircraft body 13. In a preferred embodiment, the forward and aft doors 12 and 14 are operatively connected such that opening the forward door 12 or moving the forward door 12 from the closed to the open position causes the aft door 14 to also move from the closed to the open position. Furthermore, opening the aft door 14 or moving the aft door 14 from the closed to the open position causes the forward door 12 to also move from the closed to the open position. The simultaneous opening and closing can be accomplished by mechanical mechanisms, electric mechanisms or a combination of both.

[0061] The dashed lines in FIGS. 2 and 3 show the closing path of the doors. As shown, the forward door 12 provides access to the front row of seats 16 and the aft door 14 provides access to the back row of seats 18 and the cargo hold 20. The cargo hold 20 is separated from the passenger cabin 22 by a divider member 24, which prevents passengers seated in the back row 18 from reaching back into the cargo hold 20. In another embodiment, the divider member can be omitted and access to the cargo hold 20 can be possible from the passenger area.

[0062] As shown in FIGS. 4 and 5, in a preferred embodiment, the cargo hold 20 includes a pivotable shelf 26 that is movable between a stowed position (see FIG. 4) and a deployed position (see FIG. 5). Preferably, the shelf 26 is pivotably connected to the back wall 28 of the cargo hold 20 and pivots downwardly such that it rests on a ledge 30 on the divider member 24. The shelf 26 divides the cargo hold 20 into upper and lower storage sections. In another embodiment, more than one shelf can be included. Any seating arrangement is within the scope of the present invention. As shown in FIGS. 2-3, the aircraft 10 can include forward facing seats that are separate within each row, or, as shown in FIG. 4-13, the aircraft 10 can include bench seats that are angled outwardly.

[0063] FIGS. 6-8 show another embodiment where the forward and aft doors 12 and 14 open separately or independently to provide access to the various zones. As shown in FIG. 6, the aircraft 10 includes a pilot zone 29 (cockpit or flight deck), passenger zone 31 and cargo zone 33. Opening the forward door 12 provides access to the front row 16, but with the aft door closed 14, the back row 18 and the cargo hold 20 cannot be accessed. As shown in FIG. 7, opening the aft door 14 provides access to the back row 18 and the cargo hold 20, but with the forward door closed 12, the front row 16 cannot be directly accessed. The forward door 12 can also be large enough (together with opening 11) to provide access to the pilot zone 29. In another embodiment, the pilot zone can be accessed by a separate door. In another embodiment, the forward door only provides access to the pilot zone and the aft door provides access to the entire passenger zone (the front and back rows) and the cargo hold.

[0064] As shown in FIG. 8, in a preferred embodiment, when the forward and aft doors 12 and 14 are in the open position, a protected area or space 35 for passengers to enter and exit is provided. Providing this space 35 and allowing the passengers to access the cargo zone and passenger zone from the same space can help reduce turnaround time when compared to other aircraft where the passenger zone access is in a separate location from where the cargo hold.

[0065] FIGS. 9-11 show plan views of a seating arrangement that includes the front and back rows 16 and 18 with angled seats 32. The angle preferably prevents the two adjacent passengers from being in each other's line of sight. The angled seating also aligns the passengers toward the outboard of the aircraft 10. FIG. 9 shows an angle between the seat 32 (or a vertical plane P1 that bifurcates the seat) and the longitudinal axis A1 of the aircraft 10 (or a vertical plane that bifurcates the bench seat assembly and/or the center portion). Preferably, the angle is symmetrical for the seats 32 on both sides of the aircraft 10. Also, preferably, the seats in both rows include approximately the same outward angle. The angle can be any angle between 1 and 89, but is preferably less than 45. The embodiment shown in the drawings includes an angle of 10 off the center line for both seats. FIG. 10 shows passengers seated in some of the seats and gives an example of their sight lines. Approximately the same means that the angles are within at least a few degrees of one another.

[0066] FIG. 11 shows a cockpit 34 that includes a seat for a pilot. In a preferred embodiment, the cabin 22 includes foot space 36 on opposite sides of the pilot where the front row passengers can place their feet. FIGS. 9-10 also show the foot space 36 on opposite sides of a forward area of the aircraft. As used herein, the term cockpit does not necessarily mean that room or seating is provided for a pilot. Accordingly, the space in FIGS. 9-10 (a pilotless embodiment) is still referred to as cockpit 34. Foot space for the passengers in the back row can be provided on either side of the front row seats.

[0067] FIGS. 12-16 show various configurations of bench seat assemblies 40 that include at least two seats 32 with a seat portion 42 and a back 44. The seats 32 are angled outwardly. In a preferred embodiment, the bench seat assembly 40 includes a center portion 46 that can include different components therein. FIGS. 12-14 show the center portion 46 with storage capabilities. FIG. 13 shows the center portion 46 with a drawer 48 that opens forwardly. FIG. 14 shows the center portion 46 with a cover 50 that opens upwardly to provide access to storage therein. As is shown in FIGS. 13-14, the center portion 46, drawer 48 and cover 50 are shaped such that they fit into the center portion 46. Therefore, they each have a front edge or surface 52 that has a wider or longer dimension that a rear edge or surface 54.

[0068] FIG. 15 shows a bench seat assembly 40 with a baby seat 56 in the center portion 46. The baby seat can be stowable within the center portion 46 and can deploy into the position shown in FIG. 15. In another embodiment, the center portion 46 can include the requisite attachments so that a commercially available baby seat can be connected to the center portion 46. FIG. 16 includes another seat 32 or cushion in the center portion 46. This can provide seating for a third person in the row or can provide overlap for a larger person seated in either of the seats. It will be appreciated that any of the bench seating assemblies discussed herein can be included in any of the aircraft embodiments discussed herein.

[0069] FIGS. 17-22 show further embodiments of the present invention that include separate seats in the first and second rows 16 and 18 as opposed to the bench seating shown in some of the other embodiments herein. It will be appreciated that any of the features discussed herein with respect to the other embodiments can also be included in the embodiments shown in FIGS. 17-22. FIG. 17 shows a plan view of an aircraft with symmetrical, outward angled seating, similar to the embodiments shown in FIGS. 9-11. FIG. 17 includes a contoured or curved divider member 24 that provides further space in the cargo hold 20. The curvature allows the divider to be positioned closer to the seat backs of the back row of seats, as opposed to a straight divider. This embodiment includes a central pilot seat 25, symmetrical angled passenger seats and symmetrical dividers between the various zones (divider member 24 between the cargo zone and the passenger zone, a front divider member 23 between the passenger zone and the pilot zone, and pilot doors 27 that provide access to the cockpit or pilot zone 29. Any of the doors taught herein can be openable in a manner differently than pivotable. For example, the doors can translate or slide (upwardly or sideways) between the open and closed positions.

[0070] FIG. 18 shows another embodiment that includes at least one row with asymmetrical or staggered seating. In the embodiment shown in FIG. 18, the front row includes the staggered seating and the back row seats are not staggered. In another embodiment, the back row can include staggered seating. The pilot seat 25 is also positioned to one side (e.g., the port side) of the aircraft. This provides the ability to move the seat(s) 55 on the opposite side (e.g., the starboard side) forward, thus providing more leg room for the two seats 55 on the starboard side. This can be offered as premium seating by the carrier. The seats 57 on the port side have less leg room or pitch. The front divider member 23 also has an asymmetrical shape, as shown in FIG. 18, and includes a first section 81, a second section 82 and a connector section 83. The first section 81 is positioned rearwardly or aft of the second section 82 and the connector section 83 extends therebetween. In this embodiment, the forwardmost door 27 provides access to the pilot zone 29 and the forward starboard side seat 55. In another embodiment, all of the seats can face directly forwardly and not be angled outwardly or inwardly.

[0071] FIG. 19 shows an embodiment similar to FIG. 18, but where the forward section 81 of the front divider member 23 is positioned forward of the forward door, thus allowing access to a person of reduced mobility (PRM). In this embodiment, the forwardmost door is referred to as the PRM door. The space in front of the forward seat 55 can be large enough to allow a wheelchair to fit therein so that a PRM can transfer from the wheelchair to the seat. In another embodiment, the space may be too small for a wheelchair.

[0072] FIG. 20 shows an embodiment where both the front and back rows 16 and 18 include asymmetrical or staggered seating. The cargo hold divider member 24 also is asymmetrical, thus allowing additional space in the cargo hold. As a result of the starboard side rear seat being further forward than the port side rear seat, there is more cargo space on the starboard side than on the port side. In this embodiment, the cargo hold divider member 24 includes a first section 84, a second section 85 and a connector section 86. The first section 84 is positioned rearwardly or aft of the second section 85 and the connector section 86 extends therebetween. In other words, the distance between the starboard side of the divider member 24 and the back wall of the cargo hold is greater than the distance between the port side of the divider member 24 and the back wall of the cargo hold. In the embodiment shown in FIG. 20, the stagger between the seats in the front row is different (greater) than the stagger between the seats in the back row. In another embodiment, the stagger can be the same.

[0073] FIGS. 21-22 show embodiments that include forward and aft facing seats. FIG. 21 includes symmetrical seating and FIG. 22 includes asymmetrical seating. Some cabin structure may not allow multiple doors for passenger access, in which case, a face to face seating arrangement may be the best option to allow passengers seated in the front and back rows 16 and 18 to enter through the same door (first door 12 in FIG. 21) and providing separate doors for the pilot (pilot door 27) and for the cargo zone (second door 14).

[0074] As shown in FIG. 21, the front row 16 includes aft facing sets that are angled inwardly instead of outwardly. The lines of sight for the passengers seated in the front and back rows are such that a passengers looking straight ahead is not looking directly at the other passenger seated on the same side of the cabin. Furthermore, the angle prevents facing passengers knees from interfering with one another.

[0075] FIG. 22 shows asymmetrical angled face to face seating (reducing knee interference and enabling extra foot space (e.g., that can be used for premium seating, oversized or limited mobility passengers). In FIG. 22, the seats 55 on the starboard side of the aircraft are not angled inwardly or outwardly. In another embodiment, these seats can be angled.
