Diamond shaped armrests for airline passenger seats

摘要

The functional and aesthetic aspect of the original redesign of inboard wall surfaces on airline passenger seat armrests. The new armrest cross-section contours are introduced instead of the prior art rectangular section shape with vertical side walls near the front end of the armrest. The new sections resemble a semi-diamond shape for the outboard armrests and full diamond shape for the center armrests. The new section contour changes the flat, vertical wall (10) located near upper end of armrest and between the front end (22) and midsection (24) of armrest. The new surface is comprised of a sloping wall (14) starting near the upper edge (12) and diverging from the original vertical wall (10), then the direction changes at the edge (16) to run on another slope (18) toward the original wall (10) and passes thru to form a substantial round cutout (20) behind the surface of the original vertical wall (10) of the prior art armrest. The new contour provides more legroom, measured in the lateral direction, and provides substantially wider armrests at the top surfaces without increasing overall width of the airline seats. Additionally, the Passenger Control Units (30) (PCU) are also better exposed, more accessible and are easier to operate when located on this sloping wall surface (14).
