1. A method for making garter-type axially resilient coiled spring comprising the steps of:
- fabricating by winding a metallic wire to produce coils canted with respect to a centerline of the garter-type axially resilient coiled spring, each coil having a leading portion and a trailing portion, said leading portion being disposed at a front angle, in a range from greater than 0 to 35 degrees, to a line normal to a centerline of the garter-type axially resilient coiled spring and said trailing portion being disposed at a back angle to the normal line;
during fabricating of the wire adjusting the magnitude of the back angle in order to achieve preselected load-deflection characteristics of the garter-type axially resilient coiled spring; and
attaching two ends of the wound wire in a manner forming a garter-type axially resilient coiled spring with the trailing portion along the outside diameter of the garter-type axially resilient coiled spring and the leading portion along the inside diameter of the garter-type axially resilient coiled spring.

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 a leading portion. Specific resilient performance, or load-deflection characteristics, of the spring is obtained by interconnecting the coils in a manner such that the trailing portion is disposed along an outside diameter of the garter-type axially resilient coil spring and the leading portion is disposed along an inside diameter of the garter-type axially resilient coil spring.
