摘要： A belt tensioner for a seat belt system includes a belt shaft housing, a belt shaft pivoted about an axis in the belt shaft housing, a rope reel tightly connected to the belt shaft. A tensioner drive includes a tensioner tube, a deformable plastic element guided to be longitudinally movable in the tensioner tube, a drive pinion and a pull rope which is partly wound onto the rope reel. The plastic element is adapted to engage in the drive pinion and to drive the drive pinion in the tensioning direction. During rotation of the drive pinion the pull rope is wound onto a rope drum of the drive pinion, on the one hand, and is unwound from the rope reel, on the other hand, while the belt shaft rotates.

摘要： A gas generator includes a holder made of metal having assembled thereto a cup filled with a gas generating agent and an igniter for burning the gas generating agent. The holder includes a body part, and an igniter fixing engagement part and a cup fixing engagement part projecting from the body part. These engagement parts are bent, so that the igniter and the cup are fixed by crimping to the holder. The engagement parts are both finish shaped by forging processing. A metal flow appearing in superficial layers of the engagement parts extends continuously from the body part through the engagement parts to return to the body part, without being divided in surfaces of the engagement parts.

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.
