  • Buckles for vehicle safety belts and harnesses
    Patent number: 4004115
    Abstract: A buckle for a safety belt or harness for a vehicle. The buckle comprises a plate having an aperture defined therein and a casing which separably receives the plate through an entrance slot in the casing. A latch mechanism positioned within the casing releasably latches the plate to the casing. A spring mounted in the casing has one end located closely adjacent the entrance slot and is compressed by the plate when that plate is inserted into the casing. The spring urges the plate outwardly and applies outward force thereto in an essentially continuous manner until the plate is nearly completely ejected from the casing.
