摘要： A seat belt latchplate is disclosed for use in association with a three-point seat belt harness wherein the latchplate is mounted at an intermediate point on the belt formed with a tongue portion adapted to be releasably anchored to an associated releasable buckle positioned inboard of the vehicle passenger seat. The latchplate has a trough-shaped depression providing a cross bar defined by a pair of symmetrically disposed belt slots located in each sloped side of the depression. A J-shaped lock bar is supported on the cross bar enabling the belt to be weaved through one slot and over the lock bar for passage through the other slot. With the latchplate in its free running stowed mode the belt is straight allowing the lock bar to float for free sliding travel of the belt through the latchplate slots. In its latched mode the belt is pulled around a hook-shaped portion of the lock bar causing the bar to rock and pinch the belt in its cinching mode releasably locking the passenger in the vehicle seat.
