There are plenty of examples of earlier "child seats" but these are not to be confused with actual safety seats. These non-safety seats usually hung over the back of the front seat facing forward, with no restraints whatsoever. Franks Classic Car Blog has actually obtained a grainy, black and white photograph of the Ford safety seat, which I believe was a press handout back in the day.
