Abstract
A radially resilient canted coiled springs includes a plurality of coils canted along a centerline thereof with each coil having a trailing portion and a leading portion. The disposition of the trailing portion is defined by a back angle between the trailing portion and a line normal to the centerline and the disposition of the leading portion is defined by a front angle between the leading portion and a normal line. Specific resilient performance, or load-deflection characteristics of the radially resilient canted coiled springs is determined by controlling a turn angle of the coil spring.
