Seat Belt Buckle: Description and Operation

The front inboard belt and buckle is secured to the "slide-bar" which allows buckle to move with the seat. The buckle will move fore-and-aft with changes in seat positions. The slide bar is attached to the seat track and the seat, then anchored to the floorpan. Attaching the tongue and buckle secures the occupant with both lower and upper restraints. This tongue and belt attachment can be accomplished by a single continuous movement.
