ABSTRACT:
This specification discloses a polymer spring including an elongated shank having a first end with a longitudinal slit and an enlarged portion, an integral enlarged head at a second end of the shank opposite from the first end, and an integral, cupped flange for providing a biasing force surrounding the shank and opening toward the first end. Deflection of the flange creates a biasing force tending to cause the flange to return to an undeflected state.
