Self-stowing jumpseat for aircraft

摘要

A self-stowing jumpseat consists of a seat frame that is deployed by pulling the seat frame out of a pocket formed in the edge of a bulkhead. Once the seat frame has been deployed and locked in position, the seat pan is folded down to enable a user to be seated. The seat pan is spring-loaded to fold up, so that when the user vacates the seat, the seat pan automatically folds up into the closed configuration. As it does so, an interlock lever attached to the seat pan trips the seat frame locks from their locked to their unlocked positions. The seat frame has a retraction mechanism that urges the seat into the pocket. Accordingly, as soon as the seat pan interlock lever releases the seat frame locks, the retraction mechanism causes the folded seat frame to move into the stowed position within the bulkhead.

主权项

1. A jumpseat for use in an aircraft having a bulkhead, the bulkhead having a wall surface and an edge surface, the edge surface oriented substantially normal to the wall surface, the bulkhead further comprising a hollow pocket concealed behind the wall surface, the hollow pocket having an opening formed in the edge surface, the opening having a width dimension, the jumpseat comprising:
a seat frame comprising a seat back having a back surface and a front surface, the seat back defining a seat back plane, the seat frame further comprising a seat pan having a top surface and a bottom surface, the seat pan being joined to the seat back by a hinged connection having an axis of rotation, the hinged connection enabling the seat pan to be folded upward from an unfolded configuration in which the seat pan is folded down enabling a user to sit on the seat pan to a folded configuration in which the top surface of the seat pan is adjacent the front surface of the seat back said seat frame being movable in the folded configuration in a translational direction substantially parallel to the front surface of the seat back from a concealed position in which the seat frame is contained within the hollow pocket, to an exposed position in which the seat frame is outside of the pocket and adjacent to the edge surface.
