Sparklykid - // That just cannot be correct. It implies the seat occupant has no control over the seat going backwards and forwards on it's own. //
The point I was making is - if the driver or passenger press a button to move the seat, it is moved by engine power, until the driver or passenger stops it.
The problem is, if the seat meets an obstruction, there may be no safety cut-off to prevent the seat from continuing its movement, until it is turned off, regardless of anything - and in this case, the body of a child - proving to be an obstruction.
Therefore, if the father is too stupid to realise that he is actually crushing his child, the mechanism does not stop as a safety cut-out, which would have prevented this tragedy.
