Abstract: The problem of a front seat occupant moving the front seatback so far so as to interfere with the proper positioning of a rear-facing child safety seat or to touch a child's legs while sitting in a front-facing child safety seat is solved by transforming the lower anchor into a segment of an electrical circuit with a normally open switch that is forced to the closed position when a child safety seat attachment system has attached to the lower anchor and the vehicle prevents the front seat from moving beyond a present distance toward the rear seat. The closing of the electrical circuit can be used to supply an input signal to a controller in the vehicle programmed to notify the operator that a child safety seat has been attached to prevent the front seat from moving beyond a fixed distance from the rear seat.
