Abstract

Passenger seats having improved comfort emergency egress solutions for mini suites or other types of passenger seats that have a privacy screen, wall, or sliding door that divides the passenger seat from the aisle area or other common area. Specific embodiments find particular use on-board passenger transportation vehicles, such as aircraft, where comfort and privacy must be balanced with safety and federal regulations.

First claim

What is claimed is:

1. A passenger seat egress system, for a mini suite passenger seat privacy shell that divides a passenger seat from an aisle or other common area, the passenger seat egress system comprising:
a privacy feature that offers a primary egress from the passenger seat privacy shell and a secondary egress from the passenger seat privacy shell, the privacy feature comprising a door, a primary egress feature, and a secondary egress feature, wherein the door comprises a first portion and a second portion,
wherein if the primary egress feature fails in a deployed or closed position, the secondary egress still allows a passenger to exit the passenger seat privacy shell,
wherein the primary egress comprises a sliding means such that the door is slidable into and out of a wall pocket contained in a side wall of the privacy shell in order to open and close a passageway space,
wherein the secondary egress feature comprises;
one or more breakaway hinges on the sliding door and connecting the first portion of the door with the second portion of the door; and
an emergency release mechanism between the first portion of the door and the second portion of the door, wherein the one or more breakaway hinges are activated via activation of the emergency release mechanism that allows the door to hinge and swing inward or outward, such that if sliding movement into and out of the wall pocket is blocked, the emergency release mechanism can be activated to cause the door to be hingeable,

wherein the sliding door further comprises a spring loaded feature that is biased to force the sliding door back into alignment with a plane of the side wall once opening pressure is released from the sliding door in order to clear the aisle or other common area,
wherein the emergency release mechanism is placed over the one or more breakaway hinges.

2. The system of claim 1 , wherein the one or more hinges comprise one or more vertical hinges that hinge the door away from the passageway space.

3. The system of claim 1 , wherein the sliding door comprises a plurality of vertical panels, and wherein the one or more hinges comprise vertical hinges that allow the panels to accordion fold.

4. The system of claim 1 , wherein the sliding door comprises more than one horizontal panel, and wherein the one or more hinges comprise one or more horizontal hinges that allow an upper panel to fold over a lower panel.

5. The system of claim 1 , wherein the one or more breakaway hinges are positioned along a far edge where the sliding door meets the side wall.

6. The system of claim 1 , wherein the emergency release mechanism comprises a lever, trigger, or latch that holds or otherwise maintains the door in a straight plane, wherein release or activation of the lever, trigger, or latch releases the door to swing either inward or outward from the privacy shell.
