An emergency locking device for seatbelts may be fabricated by causing the engagement of a pawl with a ratchet wherein the ratchet is coupled to a shaft upon which the seatbelt is coiled. When the motion of the ratchet is stopped by the pawl, the seatbelt cannot be extended by any amount of force. The pawl may be loosely rotatably and translationly coupled to the shaft. In addition, the pawl may be supported and guided by an inertial member such that when an impulsive force is applied to the shaft, the inertial member is displaced with respect to the pawl such that the pawl is rotated and translated relative to the guiding portions of the inertial member such that the pawl engages and locks the ratchet. The pawl may be restored to its initial condition by removal of the force and reinitialization of position with respect to the inertial member and shaft by appropriate spring mechanisms. |
