1994 Land Rover Discovery

THE SUPPORT WEBBING OF THE DRIVERS SEAT IN THIS VEHICLE FAILED IN TENSION. THE POINT OF FAILURE WAS NEAR THE MIDPOINT OF THE WEBBING SPAN. IT IS MY BELIEF THAT THE METAL SPRING SUPPORT PLACES A NORMAL FORCE ON THE TOP SURFACE OF THE WEBBING WHEN THE DRIVER'S SEAT IS IN USE. THE RELATIVELY HARD, METAL SPRING RUBS THE SURFACE OF THE WEBBING AS THE DRIVER'S WEIGHT IS SHIFTED ON THE SEAT. EVENTUALLY THIS CAUSES A WEAK AREA IN THE WEBBING AND THE TENSION PLACED ON THE WEBBING BY ITS CONNECTION WITH THE FRAME OF THE SEAT IS TOO GREAT FOR THIS WEEK AREA. THUS THE WEBBING SNAPS APART AT THIS LOCATION. WHEN THE WEBBING SNAPS, THE DRIVER IS SUBJECT TO A SUDDEN DROP IN SITTING HEIGHT. THIS WAS APPROXIMATELY 3 INCHES FOR ME. HAD THIS SUDDEN CHANGE IN SITTING HEIGHT OCCURRED WHILE OPERATING THE VEHICLE, UNDESIRED OPERATION OF THE VEHICLE COULD HAVE OCCURRED. *JB

THE DRIVERS SEAT COLLAPSED IN THE SEAT SECTION. I WAS DRIVING THE CAR WHEN THE SEAT SUDDENLY FAILED AND DROPPED ABOUT 3-INCHES. THE SUPPORT SECTION OF THE SEAT FAILED. HOWEVER, THE LEATHER SEAT COVER HELD MY WEIGHT, BUT THE SUPPORTING STRUCTURE FAILED COMPLETELY. UNDER MANY CIRCUMSTANCES THIS COULD HAVE BEEN DIFFICULT AND COULD HAVE CONTRIBUTED TO THE LOSS OF CONTROL OF THE VEHICLE. I CONSIDERED THE FAILURE TO BE OF A SAFETY NATURE AND WELL OUTSIDE OF THE DEFINITION OF NORMAL WEAR. I REPORTED THIS FAILURE TO MY LOCAL LAND ROVER DEALER AND REQUESTED LAND ROVER NORTH AMERICA BE ADVISED OF THIS UNUSUAL FAILURE. I PURCHASED TWO 1994 LAND ROVER DISCOVERY VEHICLES, NEW IN 1994. BOTH OF THESE VEHICLES HAVE NOW HAD THIS SAME FAILURE. THAT LEADS ME TO BELIEVE THIS IS A DESIGN OR MANUFACTURING DEFECT. I AM A REGISTERED PROFESSIONAL ENGINEER IN THE FIELD OF SAFETY. MY PRIMARY FIELD IS AIRCRAFT ACCIDENT INVESTIGATIONS, BUT I HAVE DONE IN EXCESS OF FIFTY AUTOMOBILE ACCIDENT INVESTIGATIONS AND RECONSTRUCTIONS.*AK
