An infant simulator with a neck linkage connecting the head to the torso which
includes at least (a) a longitudinally extending central shaft fixedly attached
to the torso proximate the lower end of the central shaft, (b) a socket fixedly
attached to the head, (c) a ball fixedly attached to the central shaft and pivotally
captured within the socket for permitting pivoting of the socket relative to the
central shaft as between a longitudinally aligned central rest position and a longitudinally
angled position, and (d) preferably a spring coaxially positioned around the central
shaft and captured between the socket and the upper end of the central shaft, whereby
the spring biases the socket into the longitudinally aligned central rest position.
