Abstract: A seatbelt pretensioning retractor assembly for use in a vehicle is provided. The seatbelt pretensioning retractor assembly includes a housing adapted for being mounted to a frame and having an interior cavity, a pretensioner tube having an arcuate and curved shape, a pretensioner wheel rotatably mounted to the housing and fixedly coupled to a spindle, a pretensioner rod disposed within the tube and a guide plate having a guide portion and a rod guide. The pretensioner rod engages with the pretensioner wheel during pretensioning. In addition, the pretensioner wheel includes a body portion, a pair of flanges radially extending from the body portion and a plurality of vanes with the cavities formed between adjacent two of the plurality of vanes.

Abstract: 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 plastically deformable polymer rod with a recessed portion. A stopper is coupled to an end portion of the plastically deformable polymer rod. A seal member is disposed between the gas generator and the stopper. The tube includes a projection extending within the tube adjacent to the exit to define a constriction portion. The constriction portion is sized to permit the recessed portion of the plastically deformable polymer rod to pass therethrough while preventing the stopper from passing therethrough.

Abstract: A seatbelt pretensioning retractor assembly for use in a vehicle is provided. The seatbelt pretensioning retractor assembly includes a housing adapted for being mounted to a frame and having an interior cavity, a pretensioner tube having an arcuate and curved shape, a sprocket rotatably mounted to the housing and fixedly coupled to a spindle, a rod disposed within the tube and a guide plate having a guide portion and a rod guide. The rod exits the tube along a perimeter of the sprocket, and toward an arcuate landing surface of the guide portion. In addition, the guide plate further includes a couple of tabs and ribs for avoiding rattling of the pretensioner tube in normal use of the retractor assembly.

Abstract: A pretensioner for a motor vehicle belt restraint system mounted to a structure of the vehicle. The pretensioner is connected to a belt restraint component that is also connected to the belt restraint system. The pretensioner includes a conduit made of tubing and having first and second ends. At least a portion of the conduit defines an elongated piston bore with a piston slideably positioned therein. A cable is attached to the piston and extends through the conduit for connection to the belt restraint component. A micro-gas generator is also located within the conduit and positioned generally opposite of the piston. Upon activation of the micro-gas generator, a gas is generated in the piston bore and drives the piston such that the piston exerts tension on the cable and thereby on the belt restrain component.

Abstract translation: 一种安装在车辆结构上的机动车辆安全带约束系统的预紧器。 预紧器连接到皮带约束部件，皮带约束部件也连接到皮带约束系统。 预紧器包括由管道制成并具有第一和第二端的导管。 导管的至少一部分限定了细长的活塞孔，活塞可滑动地定位在其中。 电缆连接到活塞并延伸穿过导管以连接到皮带约束部件。 微气体发生器也位于管道内并且大体上与活塞相对地定位。 在微气体发生器激活时，在活塞孔中产生气体并驱动活塞，使得活塞在电缆上施加张力，从而在皮带约束部件上施加张力。
