Seat and its angle regulator

Abstract

The invention discloses a seat angle regulator. The seat angle regulator comprises return springs arranged between a camshaft and a fixed part to generate elastic deformation during the rotation of the camshaft relative to the fixed part in order to control the locking or unlocking of the seat angle regulator; the middle of the fixed part has an inside concave counter bore, the return springs are arranged in the inside concave counter hole, and there is at least one group of the return springs; and each group has two return springs symmetrically arranged relative to the revolving axis of the camshaft in an axial projection plane. The completely-symmetric fixing mode of the two return springs of each group provides same-direction torques, and simultaneously side forces generated by the two return springs are equal in size and are opposite in direction, so the side forces offset, thereby a case that the return springs only provide the torques for the angle regulator without generating additional frictional force is guaranteed. The invention also provides a seat having the seat regular on the basis of the above scheme.

Description

technical field [0001] The invention relates to the technical field of seat configuration, in particular to a seat and its recliner. Background technique [0002] Seats belong to the necessary articles for life, which provide people to ride and replace the legs to support the weight of the human body, so that people's legs can be relaxed. According to different places of use and functions, the seat has many different structures. As far as the seat installed in the vehicle is concerned, its main structure is to connect a seat back at the rear end of the seat. When the occupant sits on the seat When sitting on the seat, its back can lean against the back of the chair, and there is a recliner between the back of the chair and the seat to provide the adjustment of the inclination angle of the back of the chair relative to the seat to meet the habits or needs of different passengers. Provide better comfort. [0003] The locking spring used on the traditional seat recliner mostl...

Problems solved by technology

However, the above-mentioned prior art is often limited by the design structure of the recliner, and can only be used in the design of a recliner with a relatively small number of sliders. For recliners with more than three sliders, especially high-strength recliners It is difficult to adopt this method, or the design structure of the recliner is relatively complicated, and the cost cannot be effectively controlled
