1. A garter-type axially resilient coiled spring comprising:
- a plurality of coils canted along a centerline thereof;
back angle means for both defining the disposition of a trailing portion of each coil with respect to a line normal to the centerline and for determining the working resilient range of the garter-type axially resilient coiled spring;
front angle means for defining the disposition of a leading portion of each coil with respect to the normal line, said front angle means being greater than said back angle means;
said coils being interconnected in a manner forming a garter-type axially resilient coiled spring with the trailing portion along an inside diameter of the garter-type axially resilient coiled spring and the leading portion along an outside 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 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.

7. A garter-type axially resilient coiled spring comprising:
a plurality of interconnected coils canted in a counterclockwise direction, each coil comprising a leading portion and a trailing portion, said trailing portion being disposed along an inside diameter of the garter-type axially resilient coiled spring, said leading portion being disposed along an outside diameter of the garter-type axially resilient spring, said leading portion being disposed at a front angle of less than 35 degrees to a line normal to a centerline of the garter-type axially resilient coiled spring, said trailing portion being disposed at a back angle to the normal line, said front angle being greater than said back angle. - View Dependent Claims (8, 9, 10)
