Abstract
The damper includes a cylindrical housing with a cylindrical passageway formed therewithin. A piston traverses the cylindrical passageway. A strand element is integrally molded with the piston on a first end and integrally molded with an attachment element on a second end. The portion of the cylindrical passageway through which the piston traverses when the damper is in its retracted position has a reduced diameter.
