HINGE MECHANISM FOR AIRCRAFT DOOR

摘要

A passenger door (34) is connected to an aircraft fuselage (12) by a hinge mechanism (10) having an elongated goose-neck hinge member (22). One end of the hinge-member is pivotally connected to an idler crank arm (18) that is pivotally connected to the fuselage. The other end of the goose-neck member is pivotally connected to the door (34). A guide arm (36) connected to the door and carried by the idler crank arm (18) controls door movement. An end of the guide arm (36) has a pin (48) that follows a groove in an "S"-shaped guide track (44). The shape of the track (44) causes the guide arm to initially pivot and translate the door partially inwardly into the fuselage during opening movement, and then swing the door outwardly until it is parallel with the fuselage's outer surface.
