The seat backrest adjusting mechanism is characterized in that the seat rotating frame is provided with a backrest pull rope, an air spring and a sliding device; the sliding device is provided with a hinge; and the hinge and the end part of the air spring are connected with the seat backrest frame. When in operation, control buttons arranged on the armrest are pressed, the front end of the air spring is pulled by the pull rope, the air spring is unlocked, and the backrest can be inclined downward with a certain angle; and simultaneously, due to the effect of a hinge assembly connected on the sliding device, the hinge assembly is inclined similarly, so that the rear end of the cushion is inclined downward by a corresponding angle. Therefore, the seat backrest adjusting mechanism leads passengers to be more comfortable when sitting on the seat, and leads the seat to become more harmonious and humanized.
Description
Technical field:
The utility model relates to the technical field of train seat, specifically a kind of backrest adjustment mechanism that is used for train seat.
Background technology:
China stepped into since 21 century, and science and technology and economy all enter the high speed development stage, and railway transport of passengers in the past seems and more and more can not adapt to needs of economic development.The Ministry of Railways formulated 2015 for this reason, with newly-built 30,000 kilometers speed rails, and will exercise the novel high speed train motor train unit of 1000～1200 row in China, with " the medium-term and long-term railway network development program " of the problem of thorough solution railway transport of passengers ability wretched insufficiency.Simultaneously, along with the continuous improvement of people's economic condition, living standard improves constantly, and people are also more and more higher to the requirement of the comfort level of taking train.Common domestic train seat backrest and seat cushion combination is based on fixed type, that is: backrest and cushion are unadjustable.This is not enough hommization to the passenger who takes train, because the sitting posture difference of everyone custom just there are differences the backrest of seat and the locational requirement of cushion, if backrest and cushion are unadjustable, will make a part of passenger, the passenger who particularly takes long distance train feels under the weather.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved Seat back modulating mechanism, and it is unadjustable that it can overcome in the prior art backrest and cushion, brings uncomfortable some shortcomings for passenger's journey.
To achieve these goals, the technical solution of the utility model is: a kind of Seat back modulating mechanism, it mainly comprises seat base, is located at the seat rotating stand on the seat base, and be located at seat back-rest framework and armrest on the seat rotating stand, it is characterized in that: seat rotating stand is provided with a backrest drag-line, a gas spring and a carriage, carriage is provided with a hinge, and the end of hinge and gas spring links to each other with seat back-rest framework.
During operation, press the control button that is installed on the handrail, the gas spring front end is drawn by drag-line, the gas spring release, and backrest gets final product downward-sloping certain angle; Simultaneously owing to be connected hinge assembly effect on the carriage, the hinge assembly tilts equally, makes the downward-sloping respective angles in cushion rear end, and is more comfortable when the passenger is seated like this, makes more harmonious that seat becomes, more rich's property.

The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises seat base 7, is located at the seat rotating stand 5 on the seat base, and be located at seat back-rest framework and armrest on the seat rotating stand, it is characterized in that: seat rotating stand is provided with a backrest drag-line 3, a gas spring and a carriage, carriage is provided with a hinge, and the end of hinge and gas spring links to each other with seat back-rest framework.Armrest is provided with a drag-line button, and an end of backrest drag-line links to each other with gas spring by zip termination 13, and the other end of backrest drag-line links to each other with the drag-line button by bulb termination 12.The seat underframe is provided with a foot-operated Bringing-back mechanism 6, and foot-operated Bringing-back mechanism is made up of pedal 14, pedal support 15, drag-line support 16, drag-line 17, release guide plate 18 and retracing spring 19.Pedal and pedal support are rotationally connected by bearing pin 20, and the pin-and-hole two ends on the pedal are with bearing, and locate with ring washer with axle at the bearing pin two ends.The roller 21 of pedal upper end is positioned at the linear portion place of release guide plate 18 when locking state, and during released state, pedal is stepped on, and the roller 21 of pedal upper end is positioned at the camber line segment place of release guide plate, promptly keeps released state.Because zip connects backrest and cushion gas spring simultaneously, thereby when no matter being in which kind of adjustment state, when the release pedal is stepped on, all can make backrest and cushion adjustment state be returned to initial condition fast.
In force, at first the front end with gas spring 2 is fixed on gas spring seat rotating stand fixed pivot, and gas spring is terminal to be connected with the backrest skeleton is terminal.Then head sheave before the hinge 8 is placed on the slide rail of carriage, hinge 8 is provided with pulley 22, and described pulley is embedded in respectively to form in the chute 24 to move and pays, and the hinge upper end is provided with elongated slot 23, is connected with backrest by elongated slot.The component part of carriage also has movable stand 25 except hinge, and the bearing 26 usefulness pins on the movable stand connect, and the transverse tube 27 of bearing and movable stand is integrally welded, and transverse tube and pipe support are integrally welded.End with drag-line 4 connects gas spring assembling front end, and the other end connects drag-line control button 1.To control again on the corresponding installation position that button is installed in handrail.During operation, press the control button that is installed on the handrail, the gas spring front end is drawn by drag-line, the gas spring release, and backrest gets final product downward-sloping certain angle; Simultaneously owing to be connected hinge assembly effect on the carriage, the hinge assembly tilts equally, makes the downward-sloping respective angles in cushion rear end, and is more comfortable when the passenger is seated like this, makes more harmonious that seat becomes, more rich's property.
