摘要： A seat belt buckle assembly includes a buckle housing; a plate extending from the buckle housing and defining a slot; and a bracket including a rivet engaged in the slot. The plate and rivet are configured such that, in response to an impact force that exceeds a threshold acting to pull the buckle housing away from the bracket, the slot plastically deforms, permitting the buckle housing and plate to translate relative to the bracket.

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： An object of the invention is to reduce the weight of a pretensioner by reducing the length of a piston and a wire of the pretensioner. A pretensioner (1) is used in a seat belt device and pulls a seat belt. Due to gas supplied into a cylinder (10) from a gas generator (4), a piston (20) is moved in the cylinder (10). A wire (60) is connected to the piston (20) and the seat belt and pulls the seat belt when the piston (20) moves. The wire (60) has both ends that are connected to the seat belt and has a folded portion (63) that is connected to the piston (20) via connecting means (51). The connecting means (51) has a connecting hole (24) that is formed in the piston (20) and through which the folded portion (63) passes and has a detachment preventing member (52) that is positioned between the folded portion (63) and the piston (20) to prevent the folded portion (63) from being detached from the connecting hole (24).
