The top end of the catch point 18 is restrained by the stop pawl 12 when it is rotated to contact the front end of the stop pawl 12 and moves to the first locked state of the car seat back lock as shown in fig. 3. At this time, the counterclockwise rotation of the stopper point 18 is restricted, and the body wire 20 is restrained by the right arm 172 of the lock tongue 17 and the stopper point 18 in the arc-shaped passage, that is, the movement of the body wire 20 of the backrest in the arc-shaped passage is terminated to achieve the locking in the first gear position. Meanwhile, the comfort piece 9 and the safety piece 10 are pushed by the lock tongue 17 to rotate around the first rivet 8 anticlockwise to a position matched with the left arm 171 in the first locking state so as to prevent the lock tongue 17 from rotating around the second rivet 16 clockwise to unlock, namely, the left arm 171 of the lock tongue 17 is limited and locked by the comfort piece 9 and the safety piece 10.
The external force pulls the unlocking handle 3 in the counterclockwise direction, the unlocking handle 3 drives the comfort piece 9 and the safety piece 10 to rotate clockwise by taking the first rivet 8 as a pivot, so that the front ends of the comfort piece 9 and the safety piece 10 are tilted, a channel is opened, then the stopping pawl 12 is continuously driven to rotate clockwise by taking the first rivet 8 as a pivot to overcome the pre-loading force of the stopping pawl spring 11, the stopping pawl 12 rotates clockwise by taking the first rivet 8 as a pivot, and the front end of the stopping pawl 12 tilts upwards. The front end of the stopping pawl 12 moves away from the front of the stop point 18 to free the stop point 18. The body wire 20 continues to enter the arcuate channel under the force applied to the backrest, causing the latch 17 and catch point 18 to continue to rotate counterclockwise about the second rivet 16. Until abutting against the bottom wall of the arc-shaped channel and being restrained by the channel wall, after the unlocking handle 3 is released, the front ends of the comfort piece 9 and the safety piece 10 fall into the arc-shaped channel to provide restraint for the right arm 172 of the locking tongue 17, namely, the right arm 172 of the locking tongue 17 is limited and locked by the comfort piece 9 and the safety piece 10, and the automobile seat backrest lock is operated to the second locking state, as shown in fig. 4. At this time, the body wire 20 is restrained in the arc-shaped channel by the bottom wall of the arc-shaped channel and the right arm 172 of the latch tongue 17, that is, the movement of the body wire 20 of the backrest in the arc-shaped channel is terminated to achieve the locking in the second gear position.
It will be appreciated that in either the first locked position or the second locked position, the comfort tab 9, the safety tab 10 and the stop pawl 12 are urged to rotate clockwise into the unlocked state by counterclockwise rotation of the unlocking handle 3.
