Embodiment Construction

[0038] A lot of research work has been done in this paper on the phenomenon of sliding teeth of the seat recliner in the prior art, please refer to figure 2 and combine image 3 , 4 understand that, image 3 A schematic diagram of the force on the slider showing the angle of view of the ratchet to the direction of the chute plate when the chair back is loaded forward, Figure 4 for image 3 The enlarged view of the contact part between the middle slider and the locking cam. The solid arrows in the figure indicate the direction of force of each component.

[0039] Since the seat back 10 and the ratchet 32 ​​are fixed, when the seat back 10 is subjected to an external force loaded forward, the external force will be loaded on the ratchet 32, and the ratchet 32 ​​transmits the external force to the slider 34 through tooth transmission, so that the slider 34 has a continuous rotation tendency . Objectively, there is a gap between the side wall of the slide block 34 and the g...

Abstract

The invention discloses a seat angle regulator and a seat with the same. The seat angle regulator comprises a ratchet wheel, a sliding block and a locking cam, wherein the ratchet wheel is fixedly connected with a backrest. In a locking state, the locking surface of the locking cam abuts against the locking surface of the sliding block so as to make outer ratchet teeth of the sliding block meshed with inner ratchet teeth of the ratchet wheel. The locking surface of the locking cam and the locking surface of the sliding block are provided with grooves and protrusions matched with the grooves, and the grooves and the protrusions are configured in the manner that the protrusions can be clamped in the grooves when the locking cam rotates in the unlocking direction from the locking state position. By means of the structural design of the seat angle regulator, the tooth slippage phenomenon can be avoided, and the reliability of the seat angle regulator can be improved.

Description

technical field [0001] The invention relates to the technical field of seat angle adjustment, in particular to a seat recliner and a seat with the seat recliner. Background technique [0002] Please refer to figure 1 , figure 1 It is a schematic diagram of the structure of a typical seat. [0003] As shown in the figure, a common seat includes a seat back 10 and a seat seat 20; during use of the seat, in order to meet different needs, the angles of the seat back 10 and the seat seat 20 can be adjusted appropriately, especially for automobiles. Seat, usually realizes this function by seat recliner 30. [0004] Please also refer to figure 2 , figure 2 It is an exploded diagram of a common seat recliner. [0005] The seat recliner 30 includes a ratchet 32 ​​, an unlocking cam 33 , a slide block 34 , a locking cam 35 , a central shaft 36 , a return spring 37 and a chute plate 38 . [0006] Usually, the ratchet 32 ​​of the seat recliner 30 is fixed integrally with the se...
