Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat accessories, in particular to a seat recliner with a locking mechanism. Background Technique

[0002] A seat recliner is a device installed on an automobile seat for adjusting the inclination angle of the seat back. The seat recliner allows the driver or passenger to adjust the inclination angle of the seat back according to personal needs and comfort. This angle adjustment function can help passengers find the best sitting posture, thus providing a more comfortable and healthy riding experience.

[0003] During the use of the seat recliner, the operator needs to press the adjustment device with one hand, so that the adjustment device pops up the locking pin, separates the locking pin from the locking teeth inside the seat recliner, and then the operator rotates the adjustment wheel with the other hand to adjust the inclination angle of the seat by the adjustment wheel. After adjusting the position of the seat, the operator releases the adjustment device. At this time, the adjustment device releases the restraint on the locking pin, and the locking pin is reinserted into the locking teeth inside the seat recliner, thereby realizing the locking and fixing of the seat.

[0004] In the existing ones during use, although the seat can be locked and fixed through the cooperation of the locking pin and the locking teeth, in the subsequent use process, due to the relatively small size or thin thickness of the locking pin, the locking pin often deforms due to external force, and finally the locking effect on the seat is reduced. When adjusting the seat, the operator also needs to operate with both hands at the same time, and the whole adjustment process is relatively cumbersome. Therefore, we propose a seat recliner with a locking mechanism. Content of the Utility Model

The right end of the connecting rod is fixedly connected to the left end of the adjusting plate, and the external adjusting component can be driven to rotate through the connecting rod.

[0010] Further, it further includes an installation ring and a spring. The installation ring is rotatably connected to the middle of the left wall of the installation groove through a bearing. The connecting rod is located inside the installation ring. Springs are respectively arranged between the right end of the installation ring and the left end of the first clamping disc. The springs are sleeved on the outside of the right side of the connecting rod. The thrust generated by the extension of the springs drives the rotating cylinder to move to the right and reset through the first clamping disc.

[0011] Further, it further includes a connecting seat. The connecting seat is arranged at the left end of the connecting rod and can dock the connecting rod with the external adjusting component.

[0012] Further, it further includes limiting rods. The limiting rods are arranged on the upper and lower sides of the left wall of the installation groove to prevent the first clamping disc from damaging the springs.
