Abstract
A seatbelt retractor is constructed of a ratchet wheel secured on a take-up spindle; an inertia member normally turnable with the spindle, said inertia member being, however, capable of turning relative to the spindle; a latch member provided for rotation in a webbing-releasing direction together with the spindle, whereby a pawl member can be brought into engagement with the ratchet wheel to prevent the spindle from rotating in the webbing-releasing direction; a lock device for interconnecting the latch member to the spindle when the inertia member develops a lag in rotation relative to the spindle; and a control device for shifting, depending on a wound amount of the webbing, an engaging member between a first position where the engaging member is engageable with the inertia member to prevent any further rotation of the inertia member or a second position where the engaging member is kept out of engagement with the inertia member. The control device has an engaging member supported rockably on the latch member, a control disk rotatable responsive to rotation of the ratchet wheel and a lever member movable following a guide portion of the control disk to bring the engaging member to the first position or the second position.
