Back extension incl. head rest

For our firm curved back plates we have developed a special patented back extension with a head rest which allows the quick switch between active and resting phases.  Should the little user not be restricted by the head rest during active driving, then this can be submersed into the firm curved back plate together with the extension. However, should they switch into a relaxing phase then the seat is tilted or the angle tilted and the head can find rest in the easily activated head rest.
