    • 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.
    • 机电安全带卷收器具有安全带卷收器组件,其具有围绕用于卷绕和展开安全带的旋转轴线旋转移动的卷轴; 用于选择性地旋转卷轴的马达; 离合器,其包括通过一个或多个齿轮由所述电动机驱动的过离合器; 所述离合器与所述线轴的旋转轴线同轴地对准,并与所述线轴间隔开; 并且其中在马达的向前致动时,所述离合器的离合器片线性地移动以将所述线轴联接件接合到所述线轴,并且此后绕所述轴线旋转所述线轴以启动所述安全带的卷绕。 在离合器片接合卷轴之后,电动机的反转将使离合器板离开卷轴脱离卷轴。 优选地,离合器装置是Bendix型离合器组件。 在优选实施例中,离合器片首先接合过离合器以与锁栓相配合的方式固定。
