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.
