  • High performance tightener
    Patent number: 7429012
    Abstract: A self stopping seat belt retractor is provided with a belt shaft for winding a seat belt thereonto and unwinding a wound seat belt therefrom and a housing rotatably supporting the belt shaft and having a locking device that includes a locking means for the belt shaft that can be controlled in a vehicle sensitive and/or belt sensitive manner into engagement with a toothed gearing system on that side of the housing. A tightening device operating on the belt shaft includes a drive wheel, which is, prior to the release of the tightening device, secured in a force-transmitting manner on the housing, is connectable upon release of the tightening device with the belt shaft, whereby the drive wheel of the tightening device is connectable via the locking device with the belt shaft for the transmission of force to the belt shaft.

  • Safety belt retractor having a small-structure rotation damper
    Publication number: 20050127227
    Abstract: A safety belt retractor is provided that has a force limiting device that operates with a viscous medium. The belt shaft is adapted to be coupled with a central shaft that carries a socket type piston that is movable relative to a fixed counter socket, whereby due to relative movement the viscous medium is forced between the socket type piston and the counter sockets, thereby effecting a force limitation.
