View Patent ↗Occupant support for enhanced comfort safety and utility.
1. A two-tiered occupant support in an aircraft with an axis along its length, and with a cabin with an aisle along said axis serving both tiers of said two tiered occupant support, wherein said two tiered occupant support comprises:
an upper tier and a lower tier,
Wherein the upper and lower tiers are oriented to face occupants towards the aisle in at least one sitting position;
Wherein each of the occupants have direct egress and ingress access to the aisle; and
a storage space beneath the lower tier utilized for storage for said occupants:
wherein said storage space has a front surface facing and directly adjacent to the aisle;
wherein said storage space comprises a bottom support surface that may be drawn out into the aisle for access to stored contents;
thereby providing an efficient use of cabin space in the vehicle.
2. The two-tiered occupant support in an aircraft with a cabin with an aisle as in claim 1 , wherein the support surface that may be drawn out into the aisle for access has a movable belt that is enabled to move stored items along said belt to a position above the rear of the support surface.
3. The two-tiered occupant support in an aircraft with a cabin with an aisle as in claim 2 , wherein the belt is constructed as an endless loop with one or both of rollers and slides at the front and back of the belt.
4. The two-tiered occupant support in an aircraft with a cabin with an aisle as in claim 2 , wherein the belt is constructed as an endless loop with one or both of rollers and slides below the upper section of said loop, enabled to support a load placed on the belt.
5. The two-tiered occupant support in an aircraft with a cabin with an aisle as in claim 1 :
wherein the occupant spaces of occupants on the upper tier are displaced laterally relative to the occupant facing direction of the occupant spaces on the lower level such that each of said upper tier occupant spaces lie partially above each of a first lower tier occupant space and a second lower tier occupant space;
wherein the occupant space of each of the lower tier of occupants has a ceiling as an upper boundary that has a substantially orthogonal front edge to the direction of the occupant;
wherein at least one of the upper tier of occupants has a plurality of positions comprising a sitting position and a reclining position;
wherein, the sitting position of said upper tier occupant requires a foot space of said occupant space, with a lower boundary of said foot space below the ceiling of at least one of the occupant spaces in the lower level;
an enabling architecture of said structure that staggers the occupant spaces on each of the two levels such that the front edge of the adjoining occupant space is displaced backwards on a first side and displaced forward on a second side relative to the sitting position of occupants for each of the occupant spaces, thereby enabling for the upper tier occupant space, a foot space in front of the lower tier occupant space on the first side of the upper tier occupant support, while utilizing the space above the occupant space on the lower level on the second side of the upper tier occupant support, for a reclining space at or above the ceiling of the lower occupant space beneath.
6. The two-tiered occupant support in an aircraft with a cabin with an aisle as in claim 5 , wherein as a result of the staggered architecture, the upper tier occupant space lies partially above a first lower tier occupant space on the first side of the upper tier occupant space and partially above a second lower tier occupant space on the second side of the upper tier occupant space further comprising steps for egress and ingress to at least one of the upper tier occupant spaces, mounted at the front of the second side of the first lower tier occupant space thereby said steps being located substantially below the foot space of said upper tier occupant space and utilizing an additional space from the forward displace front edge on the second side of the first lower tier occupant space.
7. The two-tiered occupant support in an aircraft with a cabin with an aisle as in claim 6 , wherein the foot space of an upper tier occupant space, has a back boundary and a bottom boundary, and wherein an integrated leg support and foot rest ( FIG. 1-1, 1-9, 1-10, 1-11 ) is enabled to substantially follow these boundaries in a first orientation where it is enabled to support the occupants feet, and wherein said foot rest is displaced laterally towards the first side of said upper tier occupant space, and wherein said foot rest is enabled to rise and reorient to a second orientation to support the occupant's legs and lie above the ceiling of the first lower tier occupant space.
8. A two-tiered occupant support in an aircraft with a cabin with the aisle as in claim 1 , comprising an occupant space with a front boundary adjoining the aisle, and with a seat bottom with a reclining position and a sitting position;
wherein said aisle is substantially orthogonal to the occupant space; and
wherein said aisle is prescribed to have predefined widths at predefined levels;
thereby limiting a position of said front boundary of said occupant space at those levels, and:
wherein each of the positions of the seat bottom has a height and a horizontal displacement relative to a reference point on the edge of the aisle; and
wherein the seat bottom has a first leg rest attached thereto, and an extending second leg rest, slidably attached to and movable relative to the seat bottom to extend the first leg rest utilizing the height and the horizontal location of the seat bottom to increase the occupant space towards the aisle at the prescribed width for a plurality of heights of the seat bottom.
9. A two-tiered occupant support in an aircraft with a cabin with an aisle as in claim 8 , further comprising a fixed element of the occupant support, and wherein the extending second leg rest is slidably attached to the seat bottom, and wherein an actuation of said extending second leg rest is enabled with a pin attached to the extending second leg rest engaged to a slot of a predetermined shape and orientation, attached to the fixed element ( FIG. 4-2 ), whereby motion of the seat bottom relative to the fixed element moves the pin in the slot which enables horizontal movement of the extending second leg rest relative to the seat bottom, thereby extending the occupant space towards the aisle within the prescribed width at said plurality of heights.
10. The two-tiered occupant support in an aircraft with a cabin with an aisle as in claim 1 with occupants facing the aisle, wherein the each occupant support comprises a seat back and seat bottom:
wherein a base of the seat back is supported by a first end of an arm substantially orthogonal to the surface of the seat back; and
wherein a second end of said arm is pivotally attached to the vehicle about a first pivot; and
wherein said seat bottom is pivotally attached to the first end of said arm about a second pivot ( FIG. 1-1, 1-9, 1-10, 1-11 ),
wherein the rotational motion of the arm thereby resulting in variation in the angle of the seat back and the position of the rear end of the seat bottom, said first pivotal support of the second end of the arm on the vehicle further comprising an actuation mechanism to displace said first pivot thereby providing an additional degree of freedom for the orientation and position of the seat back and bottom.
