Abstract
A seat belt device including a buckle receiving an apertured tongue. A cover is pivotally mounted to the buckle frame and is engageable with a pawl to pivot the pawl to and from an apertured tongue releaseably secured within the buckle. An emergency release bar attached to the pawl extends rearwardly beneath the cover and is pivotable to force the pawl away from the frame releasing the apertured tongue. A roller bar on the buckle frame and/or the apertured tongue is slidable within a pair of slots at one end of which is located a seat belt stop. A second pair of side slots opens into the main slots releaseably holding the roller bar in a position to secure the seat belt against the stop preventing relative motion therebetween.
