    摘要: A seat belt retractor (20) characterized by low mass and low operating noise, resistant to dust, moisture, and corrosion comprising: an integrally formed, quadrilaterally shaped main body portion (24). In the preferred embodiment, the frame is injection molded using 50% or greater long glass fiber plastic or die cast or injection molded metal. A spring housing wall and wall of a mechanism cover are also integrally formed in the sides of the retractor. Positioned within the spring housing wall is a spring coil guide, as well as an integrally formed anchor, which is used to hold the outer end of a rewind spring. The mechanism side of the frame further includes an integrally formed post or pin to pivotally support a locking pawl.

    摘要: A seat belt retractor assembly has a seat belt retractor for generating a retraction force to rewind a seat belt on a reel. A coupling device selectively couples and decouples the retractor from the reel. A tensioning device generates a tensioning force in the seat belt when in an activated state. The coupling device decouples the retractor from the reel when the tensioning device is activated.
