Description

The seat that the chair back and seat cushion can tilt simultaneously

The utility model relates to a kind of seat, refers in particular to the seat that a kind of chair back and seat cushion can tilt simultaneously, and when the chair back was lain down backward, chair cushion can down tilt simultaneously, but not up perk is more felt comfortable and do not had the anxiety of falling when the people is sat.

The seat of generally commonly using as shown in Figure 1, its structure mainly is: seat support 1 bottom surface is a plank 2, and this plank 2 is a two-part, wherein front side plank 3 is toward top rake, and 4 past rear-inclineds of rear side plank, face with 2 ends of plank engages with swing seat 5, joining base 6 and spring base 7 again, and this structure finds to have following shortcoming through using the back:

One, the set two-part plank 2 in its seat support 1 bottom surface can make seat support 1 produce folding line under permanent the use, even causes seat surface to break, and the seat cushion of this segmentation plank 2 and uncomfortable.

Two, the plank of this two-part can weaken the intensity of seat itself, and processing is difficult, increases cost relatively, does not meet economic benefit.

Three, this structure can't tilt synchronously, but the gradient that has a down dip by the smooth and easy front end of human body weight fully is passive type so it has a down dip, and causing seat not have comfort can say.

The purpose of this utility model is to overcome above-mentioned shortcoming, and the seat that provides a kind of chair back and seat to tilt simultaneously makes it more economical durable and comfortable safety.

The utility model is achieved in that the seat that a kind of chair back and seat cushion can tilt simultaneously, mainly by joining base, stacker and interlock body are formed, wherein the bottom inner face of joining base is provided with one and adjusts body, adjust body and be arranged with a Jiong type dome body, the three fixes with screw rod, wherein adjusting body and joining base wears round bar in the side simultaneously and combines, stacker is the Qian type, the one side places air pressure rod, opposite side wears a spring, this spring one end places in the aforesaid Jiong type dome body, the other end is positioned at the set Qian type dome body in stacker below, the interlock body is the Jiong type, the appropriate position of its front part sides face respectively is provided with the  type strip hole of a suitable gradient, and the back side top of this interlock body is set in the open-work 31 of both sides with a round bar, thereafter the side-lower two sides then respectively are provided with a circular through-hole, side at the interlock body, appropriate position, circular through-hole front lower place is then established an open-work in addition, the two sides of interlock body place in the two sides of the stacker below it, one round bar is set in the set open-work in side of joining base and stacker, and put on the collar of fixation, interlock body and stacker also are connected and fixed with the round bar and the collar, place a round bar in the  type strip hole of interlock body, the interlock body back side and the chair back are fixed.That is to say: between joining base and stacker, establish an interlock body, this interlock body front part sides face respectively is provided with the strip hole that is the  type, and place with a round bar, another round bar of mat places the set open-work of set open-work of interlock body lower rear and stacker both sides and fixes again, and the interlock body is provided with the open-work of two appropriate locations in its suitable side; When placing this side than the open-work in the place ahead with a round bar, this interlock body is fixing, and this moment, the chair back can't move, but seat cushion still can be done the action of inclination in the vertical space of the strip hole of this  type; Break away from this open-work and work as this round bar, when placing another open-work at this open-work rear with another round bar, this moment, the chair back and seat cushion all can be done the inclination of a suitable distance; Again when this round bar breaks away from this open-work, the then chair back action that can lie low, and seat cushion also can tilt.

This shows, the utlity model has following advantage:

One, the utility model can fix the chair back, makes it an angle or lie low to change as required at any time.

Two, the utility model also can be controlled and preset according to the required hypsokinesis angle is matched with oblique strip hole control or by serrated face.

Three, the utility model production and processing is fast, assembles fast and conveniently, and maintenance easily, reduces cost relatively, more meets economic benefit.

Four, the utility model is that the whole plane of chair cushion tilts, so even permanent the use also can not cause seat surface to break.

Five, the utility model is that the chair back and chair cushion tilt synchronously, thus do not have the anxiety of falling, and more comfortable safety.

Six, the utility model is to use the whole plane of going up of joining base to combine with chair cushion, so seat intensity height and handling ease.

In sum, obviously product are more easily assembled than commonly using, cost is low for the utility model, and are comfortable safe and can do synchronous inclination.
