Embodiment 1

[0035] like Figure 1-3As shown, a horizontal limit device for an armrest, the limit device is used to be assembled in the armrest, so that the armrest can be adjusted to maintain a horizontal state, the limit device includes a gravity assembly 1 and a ratchet assembly 2, the gravity assembly 1 is used for Control the unlocking and locking of the ratchet assembly 2. The ratchet assembly 2 includes a ratchet lock plate 21, a ratchet swing tooth 22, a ratchet swing tooth unlocking shaft 23 and a main shaft 24. The ratchet swing tooth 22 engages with the ratchet lock plate 21, and the ratchet lock plate 21 is used for Control the rotation and stop of the armrest, the armrest and the main shaft 24 are rotatably connected, the ratchet swing tooth 22 is rotatably connected with the main shaft 24, the gravity assembly 1 includes a gravity lock 11 and a gravity lock plate 12, and the gravity lock 11 is rotatably connected on the ratchet lock plate 21, When the gravity lock 11 is in th...

Embodiment 2

[0061] A seat is characterized in that it includes an armrest and the armrest horizontal limiting device as described in Embodiment 1. Based on the seating position of the passenger, the left armrest of the seat corresponds to the position close to the passenger's left hand, and the right armrest of the seat corresponds to the position of the passenger's left hand. Close to the right hand position of the passenger, the armrest horizontal limit device described in Embodiment 1 is installed on the left armrest of the seat, and the main shaft 24 protruding from the circular hole on the inner shell 6 is used to be installed on the left side of the seat The end face, that is, the central axis of the main shaft is perpendicular to the left end face of the seat, the inner shell 6 is the side close to the seat seating position, and the outer shell 5 is the side away from the seat seating position; When the armrest horizontal limiting device is installed on the right armrest of the seat...

Abstract

The invention relates to an armrest level limiting device, a seat and a car, the limiting device includes a gravity component and a ratchet component, the gravity component is used to control the unlocking and locking of the ratchet component, and the ratchet component includes a ratchet Lock plate, ratchet swing teeth, ratchet swing teeth unlock the rotating shaft and the main shaft, the ratchet swing teeth are engaged with the ratchet lock plate, the ratchet lock plate is used to control the rotation of the armrest, and the ratchet swing teeth are rotatably connected to the main shaft , the gravity assembly includes a gravity lock and a gravity lock plate, the gravity lock is fixedly mounted on the ratchet lock plate, the gravity lock is engaged with the gravity lock plate when it is in the first position, the gravity lock plate and The main shaft is fixedly connected, and the ratchet swing teeth are rotatably connected around the unlocking shaft of the ratchet swing teeth. Through the cooperation of the gravity component and the ratchet component, the one-way locking function of the armrest is realized; the problem in the prior art that the armrest cannot be kept horizontal after the seat back is rotated and affects the comfort of passengers is solved.

Description

technical field [0001] The invention relates to the technical field of automobile armrest parts, in particular to an armrest level limiting device, a seat and an automobile. Background technique [0002] The armrest of a car seat is an area of ​​high concern for passengers in daily use. The comfort of the armrest is directly related to the embodiment of ergonomics, thus affecting the ergonomic performance and market competitiveness of related models. Therefore, assessing the state of use of armrests is an important part of the vehicle development process. At present, the common car seat armrests on the market are mainly fixed armrests. The horizontal state of the armrests is designed according to the normal sitting posture of ordinary people. The relative locking angle between the armrests of the seat back and the backrest is fixed. The design is not humanized enough, and it is difficult to meet the comfort requirements of different users. [0003] The use of horizontal li...
