Defective Seat Belts: Buckle Unlatching

Because of a latch design defect in some seat belts, the latches can unlock with little force, rendering the harness useless in a wreck. In this segment, HLM’s Steve Lowry explains the failure, called unintended unlatching. It is prone to occur in a side impact collision when an occupant’s hand, arm or hip hits the latch.  To prevent the spontaneous release, car manufacturers should have the latches pass two key safety tests before installation to prove they are crash-worthy.
