Abstract: Spring modules for an adjustable sleeping system. At least some of the example embodiments are spring modules comprising: a spring rail, and a plurality of adjustable spring assemblies spaced along the length of the spring rail. Each adjustable spring assembly may comprise: a motor with a stator coupled to the spring rail, a lead screw coupled to the rotor of the motor, and the lead screw extending above an upper surface of the spring rail, a spring plate coupled to the lead screw, and a main spring coupled to the spring plate. Thus, the weight or force carried by each adjustable spring assembly along the spring rail is separately adjustable by a bed controller.

Abstract: A tweezer assembly includes a housing, an optically-transmissive shaft, and a flexible arm. A lamp is disposed within the housing and adjacent the opening in the housing. A battery provides electrical power to the lamp. The shaft has external threads that match the internal threads of the opening in the housing. The flexible arm includes an arched section and a clamp disposed at its proximal end. The clamp has opposing jaws that flex outward to snap in place around opposing sides of a recessed section in the shaft. The clamp thereby secures the flexible arm to the shaft such that the distal end of the arched section is disposed proximate to but not contacting the distal end of shaft. When a pressing force is applied to the arched section, the distal end of the flexible arm is operable to move into contact with the distal end of the shaft.

Abstract: A tray table assembly adapted to move to and from a stowed position in a stowage module positioned to one side of a passenger seat. The assembly includes an arcuate rail movably mounted in the stowage module, a tray table mounted on the rail for arcuate movement along the rail between the stowed position and the deployed position relative to the rail, and also mounted on the rail for fore and aft translating movement in the deployed position. The tray table rides on an arcuate rail that permits both deployment and fore and aft movement of the tray table, and automatically centers the tray table during movement toward the stowed position.
