Car-seat model
A rigid-body model of a prototypical seat is developed for use in
the present work, Fig. 1. The car-seat model comprises of the
following rigid bodies: head-rest, back-rest, seat-pan, leg-rest and
the foot-rest. Revolute joints were used to enable back-rest and
seat-pan inclination angle adjustment and a prismatic joint was
used for seat longitudinal-track position adjustment.
