Car seat recliner assembly

Abstract

The invention relates to an automobile seat angle adjuster assembly. The automobile seat angle adjuster assembly comprises a driven-side angle adjuster, a linkage rod and a driving-side angle adjuster. The left end of the linkage rod is connected to a rotating shaft of the driven-side angle adjuster in an inserted mode, and the right end of the linkage rod is connected to a rotating shaft of the driving-side angle adjuster in an inserted mode. The right end portion of the linkage rod is fixedly sleeved with a driving disc. Driving groove holes are formed in the edge of the driving disc in the circumferential direction. The rotating shaft of the driving-side angle adjuster is fixedly sleeved with a rotating disc. Shifting blocks are arranged on the outer periphery of the rotating disc and inserted into the groove holes in the driving disc. The installation structure can lower the requirement for precision of a seat frame and avoids the problems that seat backrest operating force is large and adjustment can not be carried out smoothly.

Description

technical field [0001] The invention relates to automobile parts, in particular to an automobile seat recliner assembly. Background technique [0002] As a key component in the car seat, the car seat recliner assembly directly affects the performance of the car seat. The existing bilateral synchronous recliner consists of a driving side recliner, a driven side recliner and a linkage rod, and the driving side recliner and the driven side recliner are connected through a linkage rod. The rotating shaft of the active side recliner is cylindrical, the rotating shaft of the driven side recliner is square cylindrical, the linkage rod is a hollow cylindrical tube, the left end of which is a circular hole, and the right end is a square hole, and the left end of the linkage rod passes through the The circular hole is inserted into the cylindrical rotating shaft of the driving side recliner and then welded and fixed; the right end of the linkage rod is inserted into the square cylind...

AI Technical Summary

Problems solved by technology

[0003] (1) Since the recliner on the driving side and the recliner on the driven side are fixed on the connecting plates on both sides of the backrest frame and the cushion frame with bolts, this structure makes the recliner on the driving side and the recliner on the driven side There are deviations in parallelism and concentricity; in addition, there are welding deformations and deviations in the backrest frame during the manufacturing process; when the linkage rod is welded to the rotating shaft of the active side recliner, it is difficult to adjust the angle between the linkage rod and the driving side and the driven side The rotating shaft of the device remains concentric, and the linkage rod is in a stressed state, resulting in excessive operating force and stagnation when adjusting the seat back;

[0004] (2) Due to the long length of the linkage rod, there is torsional deformation during the rotation process, which causes the unlocking of the driven side recliner to lag slightly behind that of the active side recliner, and the unlocking is not synchronized, resulting in abnormal noise of the seat
