1. A spring assembly comprising:
- a first plurality of coil means, interconnected with one another in a spaced-apart relationship, for causing the spring assembly to exert a generally constant force in a loading direction approximately normal to a tangent to a centerline of said plurality of coil means in response to deflection of the spring assembly along said loading direction;
a second plurality of coil means, interconnected with one another in a spaced-apart relationship and disposed within said first plurality of coil means, and in a cooperating relationship therewith, for causing the spring assembly to exert a generally constant force in a loading direction approximately normal to a tangent to a centerline of said second plurality of coil means in response to deflection of the spring assembly along said loading direction; and
elastic material means, disposed around and between said first and second plurality of coil means, and partially adhering to the coil means for modifying the force exerted by the spring assembly in response to deflection of the spring assembly along said loading direction, said elastic material means comprising an outer portion disposed around the first plurality of coil means and an inner portion disposed around said second plurality of coil means, said outer and inner portions being separate and unattached to one another.

Abstract
A spring assembly includes a plurality of coils interconnected with one another in a spaced-apart relationship for causing the spring assembly to exert as force in a loading direction approximately normal to a tangent to a centerline of the plurality of coils in response to deflection of the spring assembly along the loading direction. An elastic material is provided which is disposed around and between the plurality of coils, but either not bonded to or partially bonded to the coils, modifying the force exerted by the spring assembly in response to the deflection of the spring assembly along the loading direction.
