Abstract: A stowable seat is provided. The stowable seat may comprise a housing and a first track coupled to the housing. A backrest may be slidably coupled to the first track. A seat pan may be rotatable relative to the backrest. A second track may be in operable communication with the seat pan. An angle between the seat pan and the second track may increase as the seat pan translates away from the housing.

Abstract: The energy absorbing assembly may include a seat frame having a base, a seat pan coupled to the seat frame, and a deformable member disposed substantially between the seat pan and the base of the seat frame. In various embodiments, the seat pan is configured to support a passenger in a seated position and the deformable member is configured to undergo plastic deformation in response to a first compressive load on the deformable member.

Abstract: An aircrew member must be properly positioned during flight to have a view inside and outside of the cockpit and to reach all aircraft controls. However, if an ejection event occurs, the aircrew member should be properly aligned with a thrust direction of the ejection seat to prevent injury. A retracting backrest for an ejection seat is deployed pre-flight to a desired flight position. A release mechanism engages a positioning member to secure the retracting backrest in the flight position. In response to an eject signal, the release mechanism disengages from the positioning member, and both the aircrew member and the retracting backrest are hauled back to properly align the aircrew member for ejection.

Abstract: A securement mechanism for a storage compartment in a seat headrest may comprise a housing tray and a first latch disposed in the housing tray. A release button may be disposed in the housing tray and may contact the first latch. The release button may be configured to be substantially coplanar with the housing tray when the securement mechanism is in a secured position.
