Claims

[Claims for Utility Model Registration] 1. A webbing take-up reel rotatably supported on a base, a take-up spring that biases the take-up reel in the webbing take-up direction, and integrally formed on the take-up reel. a ratchet member, and a latch that takes a first position in which it engages with the ratchet member to prevent rotation of the take-up reel and a second position in which it does not engage with the ratchet member and allows rotation of the take-up reel. member, and the latch member is moved to the first position according to the drawer winding of the webbing.
7; In the tension lock mechanism comprising a bell 2 control means, the second control means: a solenoid that is energized by sensing a predetermined operation of the
A plunger which has a close position and a remote position with respect to the solenoid and receives an attractive force from the remote position toward the close position by energizing the solenoid, and an urging force that applies an urging force to move the plunger to the remote position against the attractive force. and an auxiliary means that senses that the webbing has been pulled out by a predetermined amount after the belt is attached and applies an auxiliary force to the plunger in the direction of the close position to bring the plunger to the close position, and when the solenoid is demagnetized, the biasing means moves the plunger close. 1. A tension lock mechanism for a tractor, characterized in that the tension lock mechanism is configured to be pushed back from a position to a separated position, whereby a plunger engages a latch member and brings the latch member to a second position. 2 Utility Model Registration In the tension lock mechanism according to claim 1, the ratchet member is a ratchet wheel having a plurality of teeth on the outer periphery and is fixed to the take-up reel, and the latch member is It consists of an arm having a pawl that engages with the teeth of the ratchet wheel, and a leg that engages with the plunger, and the arm is always biased in the direction of engagement with the ratchet. 5, it consists of a control plate having a cam surface on its outer periphery that the pawl of the latch member comes into contact with, and a clutch plate that can rotate within a predetermined range with respect to the control plate, and the control plate is guided by the pawl of the latch member to a predetermined position. 1. A tension lock mechanism for a sliding doctor, characterized in that the pawl is configured to mesh with teeth of a ratchet member at a certain position. 3. In the tension lock mechanism according to claim 2, the auxiliary means includes a cam means that is integrally formed on the control plate and has a cam surface on the outer periphery, and a cam means that follows the cam surface and is attached to the base. A first arm that is swingably supported, a second arm that is engageable with the plunger, and is provided between the first arm and the second arm so that the second arm presses the plunger in the direction of the operating position. A retractor tension lock mechanism consisting of a spring that biases the retractor. 4. In the tension lock mechanism according to claim 2 of the utility model registration claim, the auxiliary means includes a cam means that is integrally formed on the control plate and has a cam surface on the outer periphery, and a cam means that follows the cam surface and is attached to the base. an arm that is swingably supported and engageable with the plunger;
a retractor tension lock mechanism comprising a spring biasing the arm to push the plunger toward the actuated position;
