Abstract
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.
