DISPOSITIVO PARA SUJETAR LOS CINTURONES DE SEGURIDAD EN UN VEHICULO DOTADO DE CINTURONES DE SEGURIDAD

摘要

An apparatus for locking the seat belts of a vehicle against further extensive movement during an emergency. The belt passes through a belt clamp and a roller assembly movable with respect to the clamp. The roller assembly is set to detect inertial forces and/or accelerations of the belt of a predetermined magnitude and to lock against further rotation upon their detection, whereupon further movement of the belt in the extensive direction urges the assembly against the belt clamp, causing it to lock.
