Arm, the lock leaf has outer locked groove and interlocking slot, and lock leaf and lock sheet are pivotally connected in main pivot, and the lock sheet is left
Side forms cam mechanism to apply pretightning force to U-shaped locking bolt during the swing, and lock leaf is configured with lock leaf torsional spring, lock sheet configuration
There is a lock sheet torsional spring, the lock leaf torsional spring and lock sheet torsional spring apply anticlockwise return torque, right on the shell
The interlocking slot of Ying Suoye and outer locked groove position offer locking bolt card slot, and the lock leaf brake(-holder) block is pivotally connected and matches with shell
It is equipped with lock leaf brake(-holder) block torsional spring, lock leaf brake(-holder) block torsional spring applies anticlockwise return torque, the lock to lock leaf brake(-holder) block
With pin is opened on leaf, opens pin and enter in the strip arc groove offered on lock sheet, the unlatching rocker arm is V-shaped
Distribution, the middle part and shell for opening rocker arm are pivotally connected, and the upper end for opening rocker arm is connect with release lever, opens the lower end of rocker arm
Cooperate with lock sheet lower part, opens its lower end during rocker arm pushes up downwards and open lock sheet clockwise, the lock
The strip arc groove of tight on piece, which pulls, to be opened pin and drives lock leaf clockwise oscillation and then unlock.
After adopting the above technical scheme, the automotive seat two gear lock is by lock sheet and locks leaf brake(-holder) block from both direction pair
U-shaped locking bolt is pre-tightened, and fixed U-shaped pin position is conducive to, it is avoided to issue abnormal sound, lock leaf brake(-holder) block outer layer tool because of shaking
There is covered plastics layer, avoid U-shaped locking bolt from latching and directly impinge lock sheet, plays and eliminate the work that operational sound is trembled with reduction seat
With.
Detailed description of the invention
Fig. 1 is that the utility model opens the structural schematic diagram behind upper part of the housing；
Fig. 2 is that U-shaped locking bolt is in the structural schematic diagram that first gear is latched after the utility model opens upper part of the housing；
Fig. 3 is that U-shaped locking bolt is in the structural schematic diagram that second gear is latched after the utility model opens upper part of the housing.
Specific embodiment
Referring to shown in above-mentioned attached drawing, the gear of automotive seat two lock provided by the utility model includes shell 1 and is set in shell 1
Lock leaf 2, lock sheet 3, lock leaf brake(-holder) block 4 and open Rocker arm 5, lock leaf 2 have outer locked groove 6 and interlocking slot 7, and lock leaf 2 and lock
Tight piece 3 is pivotally connected in main pivot 8, and cam mechanism is formed on the left of lock sheet 3 to apply during the swing to U-shaped locking bolt 9
Add pretightning force, lock leaf 2 is configured with lock sheet torsional spring 11 configured with lock leaf torsional spring 10, lock sheet 3, locks leaf torsional spring 10 and lock sheet is turned round
Spring 11 applies anticlockwise return torque, and the interlocking slot 7 of corresponding lock leaf 2 and 6 position of outer locked groove open up on shell 1
There is locking bolt card slot 12, lock leaf brake(-holder) block 4 and shell 1 are pivotally connected and configured with lock leaf brake(-holder) block torsional springs 13, and lock leaf brake(-holder) block is turned round
13 pairs of lock leaf brake(-holder) blocks 4 of spring apply anticlockwise return torque, lock on leaf 2 with pin 14 is opened, open pin 14 into
Enter in the strip arc groove 15 offered on lock sheet 3, open the V-shaped distribution of Rocker arm 5, opens middle part and the shell 1 of Rocker arm 5
