BRAND NEW SAFETY 1ST COMPLETE AIR CAR SEAT REMOVED FROM BOX. CAR SEAT TECH AND MOTHER INSTALLED THE SEAT. MINOR PRESSURE WAS APPLIED TO THE TOP OF THE CAR SEAT SEAT SHELL WITH THE MAJORITY OF PRESSURE BEING APPLIED AT THE REAR-FACING BELT PATH TO CREATE A SECURE INSTALLATION. THE VERY TOP OF THE CAR SEAT SHELL IS ATTACHED TO THE REST OF THE CAR SEAT WITH A SCREW ON EACH SIDE.). THE PLASTIC SHELL APPEARS TO HAVE CRACKED AT THE SCREW AREA AND THEN A 6" LONG PIECE OF THE TOP OF THE SHELL ACTUALLY CRACKED AND FELL OFF THE TOP OF THE SEAT LEAVING A RAZOR SHARP EDGE ON THE SEAT AND ON THE BROKEN PIECE. WHILE EXAMINING WHERE THE DAMAGE OCCURRED, MOTHER ACTUALLY ACCIDENTALLY CUT HERSELF ON THE EXPOSED EDGE OF THE PLASTIC. THE SEAT WAS NO LONGER SAFE TO USE AND WAS RETURNED TO TARGET BY THE MOTHER. DUE TO THE INEFFECTIVENESS OF THE REAR-FACING RECLINE FOOT OF THIS SEAT, IT IS VERY REASONABLE TO THINK THAT UNTRAINED INDIVIDUALS WILL PLACE DOWNWARD PRESSURE ON THIS UPPER PORTION OF THE SEAT TO CREATE A 35-45 DEGREE RECLINE ANGLE....AND THIS INSTALLATION WAS DONE BY A PROFESSIONAL CPST WITH OVER 6 YEARS OF INSTALLATION EXPERIENCE. ** I CAN'T SEEM TO FIND THE CORRECT MODEL NUMBER LISTED ON THIS FORM, SO I AM ENTERING "UNKNOWN." THE MODEL NUMBER IS 22430ANV AND THE BRAND IS SAFETY 1ST. *TR
