摘要 |
The present invention is a biofidelic manikin neck comprising a butyl rubber beam inserted between an aluminum base and an aluminum top, with a stainless steel cable assembly in the middle of the beam connecting the top to the base. In a first preferred embodiment of the present invention, a pivot joint is bolted to a lug in the neck top. The joint is attached to a head mounting plate to provide head nodding action. An outer cylinder, comprised of a thick sheet of butyl rubber attached vertically around the head mounting plate and the neck base, allows the head moment to respond to the angle between the head and the torso. A second preferred embodiment of the present invention uses a torsion release swivel joint instead of a pivot joint, and uses additional strips of butyl rubber to stiffen the neck response. A third preferred embodiment uses a rectangular inner beam, and a roughly oval-shaped outer support structure. A fourth preferred embodiment uses a modified rectangular beam without any additional outer support structures, and a lateral pivot joint in addition to a torsion release swivel joint.
