Abstract

A spring assembly with two or more springs, one inside another. The spring assembly can have two springs wherein one spring is located inside another spring, and the outer spring can be a helical ribbon spring and the inner spring can be a canted coil spring to provide support to the outer helical ribbon spring. Support is provided where the helical ribbon spring may have some limitations that the inner spring is able to overcome. Limitations of the helical ribbon spring may be a limited force versus deflection curve which the additional spring support of the secondary spring may overcome.
