Abstract
A canted coil spring includes a plurality of canted coils generally canted relative to a centerline extending through the coils. At least one coil when viewed in the direction of the centerline appears to have a non-elliptical shape and a non-circular shape when the at least one coil is in the unbiased state. The plurality of coils is generally canted at a first coil angle relative to the center line. The at least one coil includes at least one section canted at a second coil angle relative to the centerline. The second coil angle is different from the first coil angle when the at least one coil is in an unbiased state.
