摘要： A seatbelt buckling device and system includes a buckle and a latch plate. The latch plate includes a pair of fingers that extend from a base portion. The buckle includes buckle housing that defines a slot that is configured to receive the fingers of the latch plate. The buckle also includes a blocking member disposed in the slot that splits the slot into first and second slot portions. The first and second slot portions are sized to receive the fingers. The blocking member restricts debris from entering a cavity of the buckle housing. The buckle further includes a depressible button for releasing the latch plate. The blocking member is arranged as a blockout portion integrated into the button or an ejector protrusion extending from an ejector disposed within the buckle.

摘要： 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.

摘要： A seatbelt pretensioning retractor assembly for use in a passenger vehicle is provided. The pretensioning assembly includes a tube in fluid communication with a gas generator and a driving element disposed therein that travels in a first direction in response to actuation of the gas generator. The driving element includes a polymer rod. A stopper is coupled to a proximal end portion of the polymer rod. A piston-safety valve member is disposed between the gas generator and the stopper and is configured to allow gas from the gas generator to pass therethrough when the gas is at or above a predetermined pressure.
