Abstract
Abstract An emergency seat belt cutter for mounting in the passenger compartment of a vehicle. The cutter has a handle, a long and narrow blade mounted longitudinally in a blade support portion integral with the handle and lugs on the handle for engagement with a sheath. The sheath has a cylindrical interior with a mounting for the inside of the vehicle, a coil spring in the bottom of the cylindrical interior and bayonet connectors for engagement with the lugs. The cutter is inserted into the sheath with pressure and a counterclockwise rotation. The cutter is removed by again applying transverse pressure and turning in a clockwise direction wherein the coil spring expels the knife into a person's palm.
