ABSTRACT:
A garter-type axially resilient coil spring includes a plurality of coils canted along a centerline thereof with each coil having a trailing portion and 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 the normal line. Specific resilient performance, or load-deflection characteristics, of the spring is obtained by controlling the back angle. At selected back angles, the leading portion may be disposed at front angles beyond the range heretofore thought possible.
