Claims

[Claims for Utility Model Registration] 1. A winding shaft means biased in the webbing winding direction; A ratchet wheel attached to the winding shaft means; A winding shaft engageable with the ratchet wheel; a pawl member capable of assuming a first position capable of preventing further rotation of the means in the webbing pull-out direction and a second position not engaging the ratchet wheel, and which normally assumes the second position; When the webbing is pulled out by the first predetermined amount and then wound again onto the take-up shaft means, the claw member is brought to the first position, and when the webbing is taken up by the take-up shaft means by a second predetermined amount, the claw member is moved to the second position. A retractor comprising an emergency lock mechanism and an auto-lock mechanism, comprising: a control means for bringing the retractor into position; and an emergency lock mechanism for detecting an emergency and preventing further rotation of the take-up shaft means in the direction of pulling out the webbing. 2. the control means: a lock arm capable of taking a first state in which the pawl member is held in the first position; a second state in which the pawl member is not engaged; and an intermediate state in which the pawl member is not brought to the first position; a biasing means for biasing the lock arm in the intermediate state toward the first state; detecting that the webbing is pulled out by a first predetermined amount from the take-up shaft means, the lock arm is brought to the intermediate state, and the webbing is taken up; a detection means for bringing the lock arm into a second state by detecting that the webbing is taken up by a second predetermined amount on the shaft means; and a detection means for taking the operating position by rotation of the webbing in the webbing pull-out direction of the take-up shaft means; It assumes a non-operating position by rotation in the winding direction, and engages with the lock arm which takes an intermediate state in the operating position to maintain it in the intermediate state against the biasing force of the biasing means, and disengages from the lock arm in the non-operating position. A retractor according to claim 1, which has an operating means that is a combination of the following: 3. The retractor according to claim 1, wherein the emergency lock mechanism includes a sensor that detects an emergency and brings the pawl member to the first position. 4. The retractor according to claim 1, wherein the first predetermined amount is approximately the entire amount of webbing.
