ABSTRACT:
A one-piece elastomeric spring having four spaced end portions all joined to and extending from a common body portion. Two end portions are commonly disposed to each side of an axis of the spring such that each end portion can independently deflect when a force is applied thereto. The one-piece spring is formed from a preform formed from an elastomer which is normally free of spring-like characteristics. The elastomer from which the preform is created has a molecular structure along with a ratio of plastic strain to elastic strain greater than 1.5 to 1. The molecular structure of the preform is oriented in at least one direction so as to allow a predetermined spring rate to be imparted to the preform whereby transmuting the preform into an elastomeric spring.
