Abstract
Abstract A garter-type axially resilient coil spring (30) includes a plurality of coils (32) canted along a centerline (34) thereof with each coil (32) having a trailing portion (40) and leading portion (42). The disposition of the trailing portion (40) is defined by a back angle (48) between the trailing portion (40) and a line (50) normal to the center-line (34) and the disposition of the leading portion (42) is defined by a front angle (54) between the leading portion (42) and the normal line (50). Specific resilient performance, or load-deflection characteristics, of the spring is obtained by controlling the back angle (48). At selected back angles (48), the leading portion (42) may be disposed at front angles (54) beyond the range heretofore thought possible.
