摘要： An electromechanical seat belt retractor has a seat belt retractor assembly having a spool rotationally moveable about an axis of rotation for winding and unwinding a seat belt; a motor for selectively rotating the spool; a clutch including an over-clutch driven by the motor through one or more gears; the clutch being coaxially aligned with the axis of rotation of the spool and linearly spaced from the spool; and wherein upon a forward actuation of the motor a clutch plate of the clutch linearly moves to engage the spool coupling to the spool and thereafter rotating the spool about the axis to initiate a winding of the seat belt. After the clutch plate engages the spool a reversal of the motor linearly moves the clutch plate away from the spool disengaging the spool. Preferably the clutch means is a Bendix type clutch assembly. In a preferred embodiment, the clutch plate first engages an over-clutch is fixed in a locking engagement to the spool.
