ABSTRACT:
Improved spring elements have a unique energy absorbing element that responds to applied loads to produce counter-acting forces that act to absorb the energy of the applied loading. The greater the magnitude of the applied loads, the more the counter-acting forces equilibrate, which enables the spring elements of the invention to accommodate a range of loading force magnitudes. The improved spring elements of the invention may be integrally formed of plastic, and are suitable for use in a variety of different articles of manufacture. Exemplary single- and double-configuration mattress spring, box spring and edge stiffener embodiments are disclosed.
