Patent number: 9731825Abstract: A method and apparatus for assisting movement of a bin into a closed position. An assistance system associated with the bin may be activated in response to a manipulation of a switch associated with the bin. The assistance system may comprise a biasing system and a switch. The biasing system may be configured to generate a force in a direction towards a closed position for the bin. A switch may be connected to the biasing system and configured to activate the biasing system when a selected amount of weight is present in the bin. The force in the direction towards the closed position for the bin may be generated in response to activating the assistance system.Type: GrantFiled: June 7, 2014Date of Patent: August 15, 2017Assignee: THE BOEING COMPANYInventors: Mark LeQuesne Cloud, Christopher Lyle Schwitters, Kwun-Wing Cheung, Paul Andrew Kinzer

Patent number: 5456529Abstract: An overhead stowage system for holding luggage above a passenger seat of an airplane has a holding bin movably coupled to a support structure of a modular design which may be preassembled prior assembly with the airplane. A motor drives a cable chain which is attached to the holding bin for moving the holding bin with respect to the structure. The motor is operatively coupled to a horizontal shaft which has a length corresponding to the length of the overhead stowage bin and which has an drive sprocket driving the cable chain as it is driven by the motor. A pulley disposed on the support structure redirects the force of the cable chain, as driven by the motor, for lifting the holding bin relative the support structure. The motor provides all or a partial force for lifting the holding bin. Switches and sensors located on the support structure and holding bin operate in accordance with the position of the holding bin relative the support structure for determining when and how the motor is to operate.Type: GrantFiled: December 30, 1993Date of Patent: October 10, 1995Assignee: The Boeing CompanyInventor: Kwun-Wing Cheung
