When the upper slide rail 4 moves to a desired position, the unlocking handle 3 is released, at this time, the unlocking handle 3 rotates counterclockwise under the release of the tangential force of the torsion spring 12, the abutting part 33 is separated from the pressing head 101, and the restoring forces of the first spring 8 and the second spring 9 in the compressed state act on the first boss 221 and the second boss 621, so that the first connecting rod 22 and the second connecting rod 62 move upward to link the outer toothed plate 2 and the inner toothed plate 6 to move upward to be clamped into the first tooth groove 11 and the second tooth groove 511, that is, the locked state is restored.
The invention also provides an automobile seat, which comprises the sliding rail locking mechanism. The sliding rail of the automobile seat is locked through the sliding rail locking mechanism, and the automobile seat is moved back and forth through unlocking the sliding rail locking mechanism.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the principles and spirit of the invention, but such changes and modifications fall within the scope of the invention.
