Abstract: An aircraft armrest may incorporate a rail roller linkage. The roller linkage may include an armrest plate, a rail attached to an aircraft seat assembly, a top roller link, and a bottom roller link. The top roller link may have a threaded upper adjustment cylinder, a pivot joint, and a pair of grooved rollers diagonally disposed on either side of the pivot. The bottom roller link may have an unthreaded lower adjustment cylinder, a pivot joint, and a pair of grooved rollers diagonally disposed on either side of the pivot. The grooved rollers may mesh with the rail. The roller linkage may include a roller adjustment screw, having a threaded portion, and extending through both of the adjustment cylinders. A compression spring may bias the roller link around the rail and may be disposed between the top roller link and the bottom roller link and surrounding the roller adjustment screw.

Abstract: A one-piece upholstery cover that covers all the visible surfaces of a typical seat such as seatback cushion, seat pan cushion, seat pan extension cushion, leg rest cushion, and leg rest extension cushion. A seat covering system is also disclosed. The seat covering system includes a single elongated piece of upholstery having a first end and a second end and a loop portion intermediate the first and second ends. A first attachment portion is adjacent to the first end of the upholstery, and at least one spring mechanism attached to the second end. A first and second pivot member are attached to opposite sides of a seat back of a reclining chair. These first and second pivot members are also fixed to a seat pedestal while a connecting member having a first end attached to the first pivot member and a second end attached to the second pivot member extends through the loop portion of the elongated piece of upholstery.
