Abstract
Chairs employed in economy-class aircraft seating often incline by rotation of the back about a fixed point, usually the rear edge of the fixed seat. While increasing the comfort of one passenger, this form of seat inclination reduces the space available for the passenger seated in the aft seat. A chair with improved cradle motion, particularly for use in aircraft, is described in which inclination may occur with little or no reduction in the space available to surrounding passengers. Inclination is achieved by the contemporaneous forward sliding of the back portion and the seat portion of the chair relative to the fixed seat frame.
