  • Patent number: 10994695
    Abstract: A seat belt retractor comprises (a) a rotatable spool on which seat belt webbing is wound and (b) a load-limiting system to limit a load applied to a vehicle occupant by the webbing. The load-limiting system includes a flow control orifice through which fluid is forced when a load in excess of a predetermined load is applied to the rotatable spool by the webbing. The cross-sectional flow area of the flow control orifice is adjustable in response to unwinding of webbing from the rotatable spool prior to a vehicle crash event and ceases to be adjustable after the crash event is in progress. The load-limiting system also includes a piston in a cylinder. The piston and cylinder are operatively coupled to the spool such that rotation of the spool causes the piston to move relative to the cylinder, which movement causes fluid to be forced through the flow control orifice.

  • Patent number: 10997956
    Abstract: A strap length adjusting apparatus includes first and second stationary plates and a middle plate disposed between them. The middle plate can rotate relative to the first and second stationary plates. A biasing device is linked to first and second coupling members between the middle plate and the first plate. The biasing device can either couple the middle plate to the first plate or decouple the middle plate from the first plate. When the first and middle plates are decoupled from each other, the middle plate can rotate with respect to the first plate, and a strap partially wound about a rod that extends from the middle plate, can wind about the rod either clockwise or counterclockwise so as to continuously change a length of the strap that extends away from the rod.
