Abstract
Abstract A simulated neck construction and arrangement is provided for coupling a head structure to a torso structure of an anthropomorphic dummy of the type used in vehicular crash testing. The simulated neck construction and arrangement comprises a plurality of interconnected swivel units interposed between the head and torso structure. The swivel units permit fore and aft tilting movement, rotary movement about an axis lying in a vertical plane of the torso structure and substantially lateral tilting movement. A viscous damping means is housed within the swivel unit permitting fore and aft tilting movement to control the rate of deceleration of the head structure during such movements.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
A neck simulation device for coupling a head structure to a torso structure of an anthropomorphic dummy, comprising: a plurality of interconnected swivel units interposed between the torso structure and the head structure; a first one of the swivel units haVing pivot means positioned to provide for forward and backward tilting movements of the head structure about an axis normal to the vertical axis of the torso structure when the latter is in an upright position, and viscous damping means housed within the first one of the swivel units to control the rate of deceleration of the head structure during forward and rearward tilting movements; an intermediate one of the swivel units having pivot means supporting the head structure for pivotal movement about an axis normal to the first swivel unit axis and lying in a vertical plane of the torso structure; and a last one of the swivel units supporting the head structure for tilting movement about an axis substantially normal to the pivotal axis of the second swivel unit.
Claim 2
Dependent Claim

Claim 5
Dependent Claim
64 words
A neck simulation device according to claim 3, in which: the viscous damping means comprises a fluid filled chamber within the first one of the swivel units, a braking member relatively movable within the chamber, and orifice means in the braking member metering flow of fluid from one side of the braking member to the other side as the head structure undergoes tilting movements.
Claim 6
Dependent Claim
59 words
