Abstract
A spindle has belt webbing wound on it. The spindle is supported for rotation in belt retraction and belt withdrawal directions. The spindle is biased to rotate in the belt retraction direction. A drive member has a longitudinal central axis and is movable in a direction along the axis from a first position to a second position. The drive member is disposed in a coaxial telescoping relationship with a rotatable driven member. A drive portion of the drive member engages a surface on the driven member to rotate the driven member in response to movement of the drive member to the second position. Rotation of the driven member causes the spindle to rotate in the belt withdrawal direction and pay out belt webbing to establish slack in the belt webbing. A notch on the driven member receives the drive portion of the drive member to block rotation of the driven member, thereby blocking rotation of the spindle in the belt retraction direction to maintain slack in the belt webbing.
