Embodiment 1

[0052] An adaptive adjustment mechanism for a backrest angle of a high-speed rail seat, the adjustment mechanism includes a backrest angle limiting mechanism and a reset mechanism.

[0053] combine Figure 2-3 , the backrest angle limiting mechanism includes an angle opening module and an angle locking module.

[0054] The angle expansion module includes a fixed block 7 , a connecting shaft 10 , a slide block 9 and an angle adjustment slideway 8 .

[0055] The angle adjustment slideway 8 is provided with the upper part of the back of the base 6, and the slide block 9 is slidably arranged in the slideway of the angle adjustment slideway 8; the fixed block 7 is fixed on the lower part of the backrest connecting plate 5 back; The two ends are respectively hinged on the outside of the fixed block 7 and the slide block 9 through connecting ears.

[0056] In the process of seat back adjustment, with the backrest connecting plate 5 leaning back, the fixed block 7 pushes the slider ...

Embodiment 2

[0061] On the basis of the first embodiment, the specific structure of the reset mechanism is further limited.

[0062] The reset mechanism includes a reset spring 13 , a push plate 20 , a push rod 22 , a reset button 21 , a pull rod 14 , a fixed sleeve 15 , a reset slider 17 , an adapter ring 19 , a pull wire 23 and a pull ring 16 .

[0063] One end of the return spring 13 is fixed on the inner edge of one side of the base 6 , and the return spring 13 and the locking slideway 11 are respectively located on both sides of the angle adjustment slideway 8 . The other end of the back-moving spring 13 is connected to one side of the push plate 20, and the other end of the push plate 20 is connected to one end of the pull rod 14, and the other end of the pull rod 14 slides through the bottom of the angle adjustment slideway 8, and is placed on the pull rod. An adapter ring 19 is formed at the end of 14, and a pull wire 23 is connected to the adapter ring 19, and the pull wire 23 pas...

Embodiment 3

[0073] On the basis of Embodiments 1 and 2, in the seat distribution of the high-speed rail seat second-class car 2+3, three seats are connected to illustrate the setting method of the reset device in the state of row seats.

[0074] In this embodiment, the structures of the seat body, the backrest angle adjustment module and the backrest angle limiting mechanism among the three seats are all the same as those in the above-mentioned embodiments, and will not be repeated here.

[0075] see Figure 7 , the inner side of the inner side of the base of the innermost seat is connected to one end of the return spring 13, the other end of the return spring 13 is connected to one side of the push plate 20, and the other end of the push plate 20 is connected to one end of the pull rod 14, The other end of the pull rod 14 slides through the bottom of the angle adjustment slideways 8 of the three seats respectively, extends into the outermost seat base 6, and passes through the backrest a...

Abstract

The invention discloses a backrest angle adaptive adjustment mechanism for a seat of a high-speed railway, the adjustment mechanism comprises a backrest angle limiting mechanism and a reset mechanism,wherein the backrest angle limiting mechanism comprises an angle opening module and an angle locking module; the reset mechanism comprises a reset spring, a pushing plate, a pushing rod, a reset button, a pull rod, a fixing sleeve, a reset sliding block, an adapter ring, a stay wire and a pull ring. The seat in the application enables a passenger in the back row to control the maximal opening angle of the seat in the front row, the comfort of both passengers in the front row and in the back row is taken into consideration; the time of a crew member spent on arranging a train is saved, the efficiency is improved; the crew member can conveniently reset the limiting mechanism from the left side and the right side; the mechanisms in the seat are mechanical structures, the energy is saved, thestructure is reliable, and the maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of high-speed railways. Specifically, it relates to an adaptive adjustment mechanism for a backrest angle of a high-speed rail seat. Background technique [0002] With the continuous development of our country's social economy, the speed of railway operation in our country has also been significantly improved, and in railway transportation, seats are an important connection between people and trains, and people's living standards in modern society have improved significantly compared with the past. Therefore, the use status of train seats is directly related to the ride comfort performance of trains, and affects people's choice of travel vehicles. [0003] In order to improve the comfort of high-speed rail seats, the backrest angle of high-speed rail seats can generally be adjusted and locked freely. It is inconvenient for passengers in the first row, especially when the passengers in the rear seats use th...
