Abstract
A seatbelt pretensioner is provided including an inner tube with a gas generator housed therein, an intermediate sleeve extending over the inner tube, and a spool portion housing the sleeve and the tube. The spool portion includes spiraling flutes thereon that correspond to a protruding member in the form of flutes or pegs extending from the intermediate sleeve. In response to the gas generator firing, the sleeve will be driven longitudinally, causing the protruding member to act on the spiraling flutes of the spool, thereby causing the spool to rotate. The intermediate sleeve can include a spiraling slot that receives a peg from the inner tube, so that the intermediate sleeve will rotate to compound the spool rotation.
