Abstract: Systems and methods are disclosed for an expanded metal filter for use with an automotive safety device, such an inflatable airbag system. The expanded metal filter is composed of a plurality of expanded metal layers, wherein when a first expanded metal layer is turned over or inverted the peaks of the first expanded metal layer conform to valleys of a second expanded metal layer, and valleys of the first expanded metal layer conform to peaks of the first expanded layer whereby the first and second expanded layers nest together.

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.
