Abstract

Side-facing belted aircraft seats include a tactile signaling unit to induce movement of the seat occupant. For such purpose, the signaling unit may be provided with a signaling lid covering a female buckle of a lap belt restraint assembly. The signaling lid is moveable between a closed position wherein engagement of a male tab of the lap belt with the female buckle is precluded and an open position wherein engagement of the male tab with the female buckle is allowed. The signaling lid thereby provides tactile stimulation when in the open position thereof to induce the seated occupant to shift on the cushioned seat so that a midsaggital plane of the occupant is aligned with an offset plane of the seat that is offset by a predetermined distance toward one side of the seat relative to a midplane of the seat.

First claim

What is claimed is:

1. A side-facing belted aircraft seat comprising:
a seat base which includes a cushioned seat for supporting a seated occupant thereon;
a seat belt assembly comprising a length-adjustable seat belt portion which is capable of encircling a lap region of the seated occupant, and
a signaling unit which houses a part of the seat belt assembly, wherein
the signaling unit provides tactile stimulation to the seated occupant to thereby induce the seated occupant to shift on the cushioned seat so that a midsagittal plane of the occupant is aligned with an offset plane of the seat that is offset by a predetermined distance toward one side of the seat relative to a midplane of the seat.

2. The side-facing belted aircraft seat as in claim 1 , wherein the length-adjustable seat belt portion includes a male tab at a terminal end thereof, and wherein the seat belt assembly includes a female buckle for removable engagement with the male tab which is housed within the signaling unit.

3. The side-facing belted aircraft seat as in claim 2 , wherein the signaling unit includes a signaling lid covering the female buckle which is moveable between a closed position wherein engagement of the male tab with the female buckle is precluded and an open position wherein engagement of the male tab with the female buckle is allowed, and wherein the signaling lid provides tactile stimulation when in the open position to induce the seated occupant to shift on the cushioned seat so that the midsagittal plane of the occupant is aligned with the offset plane of the seat.

4. The side-facing belted aircraft seat as in claim 3 , wherein the signaling lid includes a hinge to allow the signaling lid to be pivotally moved between the closed and opened conditions.

5. The side-facing belted aircraft seat as in claim 3 , wherein the signaling lid comprises a finger strap to allow manual manipulation of the lid so as to facilitate movement thereof between the closed and opened conditions.

6. The side-facing belted aircraft seat as in claim 3 , wherein the signaling lid comprises a side cut-out which visibly exposes a portion of the female buckle housed in the signaling unit.

7. The side-facing belted aircraft seat as in claim 6 , wherein the cut-out portion is sized so as to prevent the male tab from being engaged with the female buckle while the signaling lid is in the closed position thereof.

8. The side-facing belted aircraft seat as in claim 1 , which further comprises an elongated buckle cushion adjacent to the signaling unit along a back edge region of the cushioned seat.

9. The side-facing belted aircraft seat as in claim 1 , wherein the seat is a convertible toilet seat, comprised of a toilet seat that is covered by the cushioned seat, wherein the cushioned seat is movable so as to expose the toilet seat therebelow for use.

10. The side-facing belted aircraft seat as in claim 1 , wherein the seat comprises right and left arm rests, and wherein the offset plane is offset by a predetermined distance toward one of the arm rests that is in a travel direction of the aircraft.

11. The side-facing belted aircraft seat as in claim 8 , wherein the buckle cushion is formed of a resilient cushion material and the signaling lid is formed of a rigid material so as to provide the tactile stimulation to the seated passenger to shift on the cushioned seat toward the offset plane.

12. An aircraft which comprises the side-facing belted aircraft seat as in claim 1 .

13. A belted side-facing aircraft toilet seat comprising:
a seat base which includes a cushioned seat for supporting a seated occupant thereon;
a seat back;
a toilet seat covered by the cushioned seat, wherein the cushioned seat is movable so as to allow access to the toilet seat;
a seat belt assembly comprising a length-adjustable seat belt portion which is capable of encircling a lap region of the seated occupant and having a male tab at a terminal end thereof, and a female buckle for removable engagement with the male tab, and
a signaling unit which houses the female buckle, wherein
the signaling unit includes a signaling lid covering the female buckle which is moveable between a closed position wherein engagement of the male tab with the female buckle is precluded and an open position wherein engagement of the male tab with the female buckle is allowed, and wherein
the signaling lid provides tactile stimulation when in the open position to induce the seated occupant to shift on the cushioned seat so that a midsagittal plane of the occupant is aligned with an offset plane of the seat that is offset by a predetermined distance toward one side of the seat relative to a midplane of the seat.

14. An aircraft which comprises the belted side-facing aircraft toilet seat according to claim 13 .

15. An aircraft comprising a fuselage and belted passenger seats within a passenger compartment, wherein at least one of the belted passenger seats is a side-facing belted aircraft seat according to claim 1 .

16. The aircraft as in claim 15 , wherein the side-facing belted aircraft seat is a convertible toilet seat comprised of a toilet seat that is covered by the cushioned seat, wherein the cushioned seat is movable so as to expose the toilet seat therebelow for use.
