Abstract
A flexible back support for use in seats such as automobile seats or office chairs, includes a central body portion with outwardly extending support fingers such that an arch having a variable apex is formed when the back support is subtended longitudinally. The longitudinal location of an apex and the shape of the arch formed on the back support changes responsively to a load imposed by a person's back. Noise, galling, wear and rough movement between moving parts of the flexible back support are reduced by the coefficient of friction reduction method of the present invention.
