Abstract: A device for preventing protrusion of a seatbelt anchorage cable into a seat belt system buckle during operation of a pretensioner coupled with the cable and a buckle assembly, the cable of a type affixed at a first end to the pretensioner, and at a second end to the buckle assembly. The cable further having an end wrap forming a loop around a rivet affixed to a frame of the buckle assembly with the cable loop wrapping around the rivet. The device having a feature positioned adjacent to the cable loop and blocking movement of the loop into the buckle. Embodiments include; providing features of a buckle housing in the form of a tab which blocks motion of the cable loop, retainer ring element attached to the buckle frame having features which embrace the cable loop, and clips which can be attached to the buckle assembly, embracing the cable attachment.

Abstract: A guide that can be included as part of a pretensioner for a motor vehicle belt restraint system. The pretensioner includes a frame having walls that define an interior compartment. Located within the interior compartment is a piston assembly having a gas generator in communication with a piston. The gas generator creates an expanding gas that causes movement of the piston and applies tension to a seatbelt of the belt restraint system. The guide includes an opening through which the seatbelt passes and that causes the seatbelt to form a reduced width configuration upon exiting the guide.

Abstract: The seatbelt pretensioner, which is designed for reducing slack in seatbelt webbing upon deployment in response to a triggering event, comprises an igniter that generates gas in response to the triggering event, an elongate body defining a chamber for receiving and the confining gas generated by the igniter, a piston movable within the elongate body by the gas generated, a slack-reducing assembly that responds to movement of the piston and is connected to at least a portion of seatbelt webbing, movement of the piston causes the slack-reducing assembly to move the seat belt webbing reducing slack in the seatbelt webbing; and a controlled pressure release that enables gas to escape from the elongate body after deployment, relieving gas pressure within the pretensioner. The controlled pressure release may comprise one or more of various pressure relieving features such as a porous intermediate disposed between the vent hole and the gas within the elongate body, a piston having a porous portion and/or a safety valve, and one or more plugs that seal vent holes in the elongate body that become unsealed by loosening the pretensioning assembly.
