Abstract
Abstract A four pivot linkage to simulate head/neck kinematics. The linkage has a ch-roll link which rotates about a first pivot fixed in an upper body and which secures the lower end of a neck link in a second pivot. The upper end of the neck link is secured in a third pivot fixed in a yaw-pitch link which in turn articulates about a fourth pivot fixed in a head.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
97 words
An apparatus for simulating head/neck kinematics comprising: a roll-pitch link having means for pivotable attachment to the torso of an anthropomorphic dummy; a yaw-pitch link having means for pivotable attachment to the head of said anthropomorphic dummy; and; a neck link having an arcuate form, the upper end of said neck link being pivotally connected to said yaw-pitch link and the lower end of said neck link being pivotally connected to said roll-pitch link such than when said apparatus is attached to said anthropomorphic dummy a four pivot linkage is formed between the torso and the head.
Claim 2
Independent Claim
97 words
An apparatus for simulating head/neck kinematics comprising: a roll-pitch link having means for pivotable attachment to the torso of an anthropomorphic dummy; a yaw-pitch link having means for pivotable attachment to the head of said anthropomorphic dummy; and; a neck link having an arcuate form, the upper end of said neck link being pivotally connected to said yaw-pitch link and the lower end of said neck link being pivotally connected to said roll-pitch link such than when said apparatus is attached to said anthropomorphic dummy a four pivot linkage is formed between the torso and the head.
Claim 3
Dependent Claim
23 words
An apparatus as recited in claim 1 wherein the pivot axes of the upper and lower ends of said neck link are orthogonal.
