THE SEAT THAT HOUSES THE INFANT SAFETY SEAT CAN BE LIFTED TO ALLOW PASSENGERS IN THE FAR BACK OF THE MINIVAN. I HAD LET MY DAUGHTER IN THE BACK SEAT AND THOUGHT I HAD LOCKED THE SEAT BACK IN PLACE. I THEN BUCKLED MY 15 MONTH OLD DAUGHTER INTO THE 5 POINT RESTRAINT, BUILT-IN CAR SEAT. WHILE DRIVING, WE CAME TO A QUICK STOP AND THE ENTIRE SEAT FLEW FORWARD, HITTING MY DAUGHTER'S HEAD ON THE SEAT IN FRONT OF HER. SHE SUSTAINED AN ABRASION TO HER FOREHEAD AND VOMITTED IMMEDIATELY AFTER THE IMPACT. SHE HAS HAD NO FURTHER PROBLEMS. I AM CONCERNED THERE IS NO WARNING ON THE SEAT THAT HOUSES THE CHILD SAFETY SEAT TO LET YOU KNOW WHETHER IT HAS BEEN LOCKED IN PLACE. THE SEAT IS HEAVY AND EVEN WITH PULLING FORWARD, IT MAY SEEM LOCKED. THERE SHOULD BE SOME WAY TO CONFIRM THIS SEAT IS LOCKED IN PLACE. *AKY
