Abstract
The utility model discloses a seat structure which can finish cooperative adjustment of backrest and seat cushion according to different sitting postures of users without the help of any operating appliance or operating process. When the users are sitting with any posture, the seat can make head, back, waist and hip acquire better support and meet the demand of human hygienic in a maximum way.
Description
The utility model relates to a kind of seat, the seat of seat that particularly relates to and flexibly connect and backrest combination.
Adjustable seat on the existing market, the adjustment of its backrest and seat cushion mostly are the guiding mechanism independent regulation by separately, and the shortcoming of this adjustment mode has: the one, and the guiding mechanism complexity; The 2nd, difficulty satisfies the hygienic requirement of human body.
The purpose of this utility model provides a kind ofly only need not finish backrest and the coordinately regulated seat of seat cushion by means of any operation utensil or operating procedure according to user's sitting posture, this seat can satisfy the user to greatest extent when any sitting posture, its head, back, waist and buttocks all obtain best support, rest, meet the hygienic requirement of human body fully.
For achieving the above object, the utility model connects with the backrest middle part by hinge at armrest rear end, the backrest bottom connects with the seat cushion tail end by hinge, and an arc-shaped guide rail respectively is set below the handrail of both sides, and seat cushion can slide on arc-shaped guide rail by slide block fixed thereon.
Of the present utility model have a following advantage: one, simple and reliable for structure; Two, backrest and seat cushion are to be stress point and changed by force direction and coordinately regulated that this makes that each position of human body is stressed appropriate along with people's sitting posture changes, and comfortableness increases greatly, meets the human body hygienic requirement.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model schematic diagram.
As shown in Figure 1, when the user swings back, headrest and backrest 1 are subjected to a thrust, seat cushion 3 downward pressure reduce, and also obtain a thrust forward, thereby make backrest 1 rotate around the hinge axis that connects with handrail 2 tail ends, the part circular motion is made around handrail 2 rear ends in seat cushion 3 rear ends simultaneously, move along guide rail 4 by slide block 5 in its front portion, in other words, and the also upwards lifting forward of seat cushion 3 this moment; Active force strengthens, and can reach the flat state that crouches substantially.When raising upper body, promptly alleviate the headrest and the pressure of backrest 1, human body gravity great majority are added on the seat cushion 3, thus backrest 1 first half lifting, seat cushion 3 backward with move down.As an embodiment, its handrail 2 is fixed on the chair leg 6.
For improving the collaborative stability of adjusting of backrest and seat cushion, can on the slide block on seat both sides, respectively add a governor motion, adjust the frictional force between slide block and the guide rail, to guarantee when arbitrary sitting posture, this chair all maintains a relatively stable state, and for example, this guiding mechanism can be a locking handwheel.
