Inclination angle adjusting mechanism of seat

Abstract

The invention discloses an inclination angle adjusting mechanism of a seat, which comprises a seat frame and an inner frame, wherein the left side and the right side of the front end of the inner frame are rotationally connected to the inner side of the seat frame, the rear end of the inner frame is rotationally connected with a rotating mechanism, one end of the rotating mechanism is rotationally connected with the rear end of the seat frame, the other end of the rotating mechanism is connected with an adjusting assembly, the adjusting assembly comprises an upper shell and a lower shell which can rotate relatively, the upper shell is fixedly connected with the seat frame, the lower shell is fixedly connected with the rotating mechanism, an inner gear ring is arranged on the inner side of the lower shell in the circumferential direction, a plurality of tooth blocks are further movably arranged in the lower shell, tooth-shaped structures are arranged on the outer sides of the tooth blocks, first clamping hooks are arranged on the inner sides of the tooth blocks, a rotating block located on the inner side of the tooth block is rotationally connected into the lower shell, and a second clamping hook opposite to the first clamping hook is arranged on the rotating block. By means of the mode, the inclination angle adjusting mechanism of the seat is firm in locking, convenient to operate, smaller in actual occupied space, easier to produce and convenient to install, and then the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of truck seats, in particular to an inclination adjustment mechanism of the seat. Background technique [0002] Most of the inclination angles of the seat cushions of truck seats on the market today are gear plates and lock tongues. The gear plates and lock tongues need to be manufactured with high precision, and assembly needs to be assembled. Disadvantages of this type of structure: the locking teeth are not easy, and it is easy to misalign the left and right teeth, resulting in inability to unlock; the unlocking operation is complicated; over time, the lock tongue will wear out in the tooth plate, the gap will become larger and larger, and the amount of seat shaking will become larger. Large, increasing the driver's risk. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a reclining mechanism of a seat, which is reliable in locking, easy to operate, rea...
