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.
Claims2
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.
