ABSTRACT:
A seat belt buckling system has a switch mechanism in the seat belt anchor plate which prevents starting of the engine until the seat belt has been buckled. The switch mechanism includes a switch controlling actuation of the starter which is only closed by insertion of the anchor plate on the belt into the buckle locking system. Means are provided to lock the plate into the buckle locking mechanism when it has been inserted sufficiently to permit starting of the engine. A rockable latch member within the locking system is actuated by a manually manipulable key plate which plate, when pressed downwardly, will permit the anchor plate to be released without interrupting the ignition after the engine has been started.
