A neck assembly for an anthropomorphic test device comprising: a plurality of vertebra discs having an uppermost disc; a joint element disposed between each respective pair of said vertebra discs; and a torsion assembly (50; 70) comprising: a neck interface plate mounted to said uppermost disc with said neck interface plate having a plurality of spaced torsion stops; an upper member coupled to said neck interface plate and configured for supporting a head assembly of the ATD with said upper member rotatable from a neutral position to a turned position relative to said neck interface plate about an axis A extending through said upper member and said neck interface plate, said upper member having a stop portion selectively engaging one of said torsion stops during an impact condition to prevent further rotation in a turned position; a resilient member having a plurality of projections positioned between said upper member and said neck interface plate with said resilient member engaging said upper member for at least partial concurrent movement during said rotation of said upper member relative to said neck interface plate from said neutral position towards said turned position wherein said plurality of projections bend in a direction responsive to a direction of rotation of said upper member relative to said neck interface plate about said axis A during said impact condition, characterized in that said resilient member has a hub portion with said plurality of projections fixed to and disposed radially outward from said hub portion such that portions of said hub portion and said plurality of projections bend in said direction responsive to a direction of rotation of said upper member relative to said neck interface plate about said axis A during said impact condition, and wherein an end portion of each of said plurality of projections are secured to said neck interface plate. a plurality of vertebra discs having an uppermost disc; a joint element disposed between each respective pair of said vertebra discs; and a torsion assembly (50; 70) comprising: a neck interface plate mounted to said uppermost disc with said neck interface plate having a plurality of spaced torsion stops; an upper member coupled to said neck interface plate and configured for supporting a head assembly of the ATD with said upper member rotatable from a neutral position to a turned position relative to said neck interface plate about an axis A extending through said upper member and said neck interface plate, said upper member having a stop portion selectively engaging one of said torsion stops during an impact condition to prevent further rotation in a turned position; a resilient member having a plurality of projections positioned between said upper member and said neck interface plate with said resilient member engaging said upper member for at least partial concurrent movement during said rotation of said upper member relative to said neck interface plate from said neutral position towards said turned position wherein said plurality of projections bend in a direction responsive to a direction of rotation of said upper member relative to said neck interface plate about said axis A during said impact condition, characterized in that said resilient member has a hub portion with said plurality of projections fixed to and disposed radially outward from said hub portion such that portions of said hub portion and said plurality of projections bend in said direction responsive to a direction of rotation of said upper member relative to said neck interface plate about said axis A during said impact condition, and wherein an end portion of each of said plurality of projections are secured to said neck interface plate. a neck interface plate mounted to said uppermost disc with said neck interface plate having a plurality of spaced torsion stops;
