Description
Technical field
The utility model relates to a kind of high-speed train chair cushion backrest linkage, and specifically a kind of seat basin (promptly supporting the skeleton of cushion) of realizing both can move forward and backward distance, can make the device that respective angles changes according to the angle change of backrest again.
Background technology
The train of high-speed cruising, the seat that need adapt with it is to satisfy passenger safety and comfortable sitting posture requirement.Existing train passenger seat major part is fixed cushion and backrest structure, takes this kind seat on the train of speed per hour more than 200 kilometers, and it can not satisfy the traveling comfort requirement is conspicuous.And Chain cushion is when itself having the function that moves forward and backward, can also change according to the backrest inclination angle make self-angular adjustment, and be to satisfy an importance of traveling comfort according to the theory of human engineering.According to the human engineering theory, cushion move forward and backward adjustment, can adapt to the demand of different passengers' different human body size to the Chain cushion position; And change with backrest angle by cushion, angular adjustment can suitably reduce passenger's degree of fatigue in the traveling comfort that improves the passenger automatically.The guide tracked structure of the many employings of Chain cushion is in the past used mechanical lock and releasing device, and the design of part complexity is just made parallel motion when cushion moves, also can't make corresponding action according to the rotational angle of backrest.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high-speed train chair cushion backrest linkage simple in structure, easy to use, it both can realize that cushion and backrest independently moved separately and rotate, can realize the function of interlock mutually again, to satisfy the needs that the different sitting postures with backrest of train seat cushion are regulated, overcome the above-mentioned defective that prior art exists.
The technical scheme of the utility model technical solution problem is as follows:
A kind of high-speed train chair cushion backrest linkage comprises cushion skeleton, backrest skeleton and support frame, it is characterized in that: also comprise cushion adjusting cylinder, connecting arm, back support, backrest adjustment cylinder; The described cushion skeleton left and right sides is provided with chute;
Cushion adjusting cylinder one end and cushion skeleton are hinged, and the other end and support frame are hinged;
Support frame is provided with orienting lug, and described cushion skeleton is being arranged on the support frame of leading and can move forward and backward with the orienting lug;
Two side lower ends are respectively equipped with the angle modulation plate about described backrest skeleton, and described angle modulation plate and back support are hinged, and described back rest supports is fixedly installed on the support frame; Backrest adjustment cylinder one end and angle modulation plate lower end are hinged, and the other end and support frame are hinged;
Described connecting arm one end is provided with elongated slot and the angle modulation plate is hinged, the other end is provided with two first pulleys arranged side by side and second pulley, first pulley embeds to form in the chute to move and pays, and second pulley is resisted against and forms stressed support on the cushion skeleton framework, and is hinged with support frame in the middle of the described connecting arm.
The utility model is to use like this: when cushion skeleton need move forward, open the valve that cushion skeleton is regulated cylinder by handling flexible axle, cushion skeleton overcame cushion skeleton and regulated the cylinder returning place force and move forward under the application force of human body sitting posture this moment.When backrest need rotate, open the backrest adjustment cylinder valve by handling flexible axle, overcome the returning place force of backrest adjustment cylinder this moment under the application force of human body sitting posture, realize that backrest rotates backward, and changes human body sitting posture.When cushion skeleton is adjusted to the reach position, when regulating the backrest rotation again,, realize the interlock function of backrest and cushion skeleton, and the cushion rear end is downward-sloping by the effect of connecting arm, maximum angle and horizon are 6 degree.
By above disclosed technical scheme as can be known, the utility model can be realized the cushion locomotive function easily by adopting cooperating of cushion and connecting arm pulley.Symmetrically arranged slip is paid and mobile guide, and the part of having avoided factors such as unbalance stress to cause is impaired, problems such as reduction in service life; By adopting being rotationally connected of backrest and back support, can realize the rotation of backrest easily; By adopting being connected of connecting arm and backrest and cushion, the interlock function of realization backrest and cushion satisfies the demand of train seat traveling comfort.
