PE88061 · Seat Tether Failure

Opened Jun 21, 1988 · Closed Sep 12, 1988

Status: closed (inferred from source dates) · Seats

SUMMARY: TRUCK DRIVER REPORTS SEAT TEATHERS ARE NOT PROPERLY ADJUSTED AT FACTORY, ALLOWING SEAT TO HINGE FORWARD IN A COLLISION. TEATHERS ACT AS RESTRAINERS, AND IF IMPROPERLY ADJUSTED SEAT BELT IS USELESS AS IT IS ATTACHED TO THE SEAT. DURING SUDDEN DECELERATION OR COLLISION THE WHOLE ASSEMBLY HINGES FORWARD ALLOWING POSSIBLE FACIAL CONTACT WITH THE WINDSHIELD.===
