Problems solved by technology

However, when the armrest is put down, the height of the armrest is fixed and cannot be adjusted. Drivers and passengers of different physiques will feel uncomfortable when using the armrest in a horizontal or approximately horizontal state, but they cannot adjust the height according to their own feelings, and the user experience is poor. Low willingness to use
[0003] Although some height-adjustable armrests are also provided in the prior art, there are defects such as large volume, few gears, high resistance during the adjustment process, and the need for both hands to cooperate to adjust, etc., which cannot meet market demand.

Embodiment 1

[0041] like figure 1 , figure 2 , image 3 , Figure 4 Shown is Embodiment 1 of the present invention, which discloses a seat armrest height adjustment mechanism, including an outer ratchet 5, a pawl seat 6, a ratchet 7 and a fixed shaft 3, the outer ratchet 5 and the seat armrest 1 Fixed connection, the ratchet base 6 is fixedly connected with the fixed shaft 3, the fixed shaft 3 is fixedly connected with the seat back, the ratchet seat 6 is arranged in the outer ratchet 5 and can rotate relative to the outer ratchet 5, and the ratchet 7 is arranged on the ratchet seat 6 and can rotate relatively with the ratchet seat 6, the corresponding ratchet 7 on the outer ratchet 5 is provided with a plurality of ratchets 5-2, when the outer ratchet 5 rotates toward the first direction relative to the ratchet seat 6, the ratchet 5-2 can Over the ratchet 7, when the outer ratchet 5 rotates in the second direction relative to the ratchet seat 6, the ratchet 5-2 meshes with the ratchet...

Embodiment 2

[0063] This embodiment discloses a car seat, which includes a backrest and an armrest, and also includes the seat armrest height adjustment mechanism described in Embodiment 1. The seat armrest height adjustment mechanism is arranged at the rear end of the armrest, and the armrest passes through the seat armrest height. The adjustment mechanism is connected with the backrest.

[0064] According to the design requirements, the armrest is at the lowest position (horizontal or approximately horizontal), and can be lifted around the fixed axis in 3 directions approaching the backrest. Each time a gear is lifted, it can only be lifted in one direction during the gear adjustment stage. up, not reverse down. In this way, it is convenient for drivers and passengers to place their arms at a more comfortable position. After reaching the highest gear, if you need the position height of other gears, you need to lift the armrest to the highest position (vertical or nearly vertical), then ...

Abstract

The invention relates to a seat armrest height adjusting mechanism and an automobile seat; the seat armrest height adjusting mechanism comprises an outer ratchet wheel, a pawl seat, a pawl and a fixing shaft; the outer ratchet wheel is fixedly connected with a seat armrest, the pawl seat is fixedly connected with the fixing shaft, and the fixing shaft is fixedly connected with a seat backrest; the pawl seat is arranged in the outer ratchet wheel and can rotate relative to the outer ratchet wheel, the pawl is arranged on the pawl seat and can rotate relative to the pawl seat, a plurality of ratchets corresponding to the pawl are arranged on the outer ratchet wheel, and the ratchets can cross the pawl when the outer ratchet wheel rotates towards the first direction relative to the pawl seat; and when the outer ratchet wheel rotates towards the second direction relative to the pawl seat, the ratchet is meshed with the pawl to limit the height of a seat armrest. The seat armrest height adjusting mechanism provided by the invention has the advantages of being compact in structure, small in size, multiple in adjusting gear, smooth in adjusting process, easy to operate, wide in application range and the like.

Description

technical field [0001] The invention belongs to the technical field of car seats, in particular to a seat armrest height adjustment mechanism, and also to a car seat. Background technique [0002] The seat on the car, in order to ride comfortably and safely, is usually provided with armrests on both sides or one side of the backrest. The position of the armrests can be adjusted. On the armrest, when not in use, put the armrest away (vertical or nearly vertical), so that it is convenient for drivers and passengers to get on and off the car. However, when the armrest is put down, the height of the armrest is fixed and cannot be adjusted. Drivers and passengers of different physiques will feel uncomfortable when using the armrest in a horizontal or approximately horizontal state, but they cannot adjust the height according to their own feelings, and the user experience is poor. The willingness to use is low. [0003] Although some height-adjustable handrails are also provided...
