According to the forward movement type backrest adjustable chair disclosed by the utility model, the sitting frame can be used for driving the backrest frame to move forwards; and simultaneously, the backward inclination regulation of the backrest frame is linked, the purpose of preventing occupying back space is achieved, the structure is ingenious, the regulation is flexible, and the forward movement type backrest adjustable chair is very suitable for being used as the sitting frame of a massage chair.
Description
Technical field:
The utility model relates to a kind of shift-forward type backrest barbed chair, and especially when backrest fold-down, seat can be lived front mobile seat.
Background technology:
As everyone knows, the adjustable dual purposes of sitting and lying chair of backrest is when it is regulated at backrest angle, when also soon backrest was suitably set level, backrest can retreat, and needs the rear portion that enough spaces are arranged, otherwise namely can meet on other object or body of wall, especially large-scale massage armchair, all the more so, each use all needs the position of adjusting seat, obviously extremely bother, if the position of adjusting seat chair not reserves the large quantity space at rear portion again, need more spacious field of employment, mostly can't satisfy this service condition at home.How to improve the structure of existing backrest barbed chair, when making the backrest hypsokinesis, can toward the mechanism of reach, namely become the object of the utility model research.
Summary of the invention:
The purpose of this utility model is that a kind of backrest axle of design is positioned on mobile seat, and seat is pedestal forward lead relatively, and regulates the shift-forward type backrest barbed chair of backrest hypsokinesis.
Technical solutions of the utility model are achieved in that a kind of shift-forward type backrest barbed chair, include seat and back rest, it is characterized in that also comprising a base, seat slides by track and is positioned on base, also be provided with driving mechanism between the two, drive seat reach or backward movement by this driving mechanism, an arc chute is respectively established in described base both sides, and two arc chutes in opposite directions and become symmetrical structure; Described back rest middle and lower part is positioned on seat by bearing pin, and both sides, back rest bottom are separately installed with roller, and two rollers drop on respectively in two arc chutes, and the formation activity is spacing.When driving mechanism drove the seat reach, two arc chutes moved relatively afterwards, and two rollers that force the back rest bottom move toward the high position of arc chute, when impelling backrest to move forward along with seat, and tilt adjustment backward, hypsokinesis and do not account for back space.
Described back rest both sides are stiffener respectively, and described roller is arranged on stiffener, and back rest is located by bearing pin mutually by this stiffener and seat.Utilize this stiffener to regulate the position of bearing pin, stressed support is more reasonable.
Described base both sides are provided with the landing part of abduction, and the seat land are on the landing part, and by the track location of sliding; Described track refers to be fixed on the guide groove on the base landing part, is fixed on the guide rail of seat one side, and guide rail forms the location of sliding among being located in guide groove, avoids seat to break away from base.
Two guide rails of described seat front portion are other is separately installed with the castor that lands, and when being beneficial to the seat reach, supports by two castors that land, and reduces the length of base and track.
Described driving mechanism is electric pushrod, cylinder, and perhaps the combination of screw mandrel screw selects a structure.
When the utility model drove the back rest reach by seat, the hypsokinesis of interlock back rest was regulated, and reaches the purpose that does not account for back space, and structure is ingenious, and flexible adjustment is suitable as the seat of massage armchair very much.

The specific embodiment:
With reference to Fig. 1, Fig. 2 and Fig. 3, shift-forward type backrest barbed chair includes base 1, seat 2 and back rest 3, and seat 2 slides by track and is positioned on base 1, also is provided with driving mechanism 4 between the two, drives seat reach or backward movement by this driving mechanism 4; Base 1 both sides are provided with the landing part 11 of abduction, and seat 2 land are on landing part 11, and by the track location of sliding; Described track refers to be fixed on the guide groove 12 on base landing part 11, is fixed on the guide rail 21 of seat 2 one sides, and guide rail 21 forms the location of sliding among being located in guide groove 12, avoids seat 2 to deviate from; Described base 1 both sides are respectively established 13, two arc chutes 13 of an arc chute in opposite directions and are become symmetrical structure; Back rest 3 middle and lower parts are positioned on seat 2 by bearing pin 5, and back rest 3 both sides, bottom are separately installed with roller 31, two rollers 31 and drop on respectively in two arc chutes 13, and the formation activity is spacing.Further say, at back rest 3 both sides difference stiffeners 32, described roller 31 is arranged on stiffener 32, and back rest 3 is located by bearing pin 5 mutually by this stiffener 32 and seat 2.The design of stiffener 32 not only can be strengthened back rest 3 intensity, and can adjust bearing pin 5 and roller 31 rational Support Position, so that lighter driving can reach back rest 3 hypsokinesis campaigns.
In addition, the two other castors 22 that land that are separately installed with of guide rails 21 in seat 2 front portions, like this when seat 2 front shifting movement, the front portion can rely on two castors 22 that land to support, thereby reduces the length of base 1 and track.
Above-mentioned driving mechanism 4 preferred versions are electric pushrod, certainly also can use cylinder, perhaps screw mandrel screw combination.
With reference to Fig. 4, shift-forward type backrest barbed chair erectility figure is also normal condition, and the roller 31 of back rest 3 bottoms is in the rearward end of arc chute 13 at this moment; When driving mechanism 4 drives seat 2 reach processes, seat 2 drives back rest 3 and together moves forward, the roller 31 of back rest 3 bottoms is subjected to arc chute 13 constraints, can only slide toward arc chute 13 front ends, due to the up perk of arc chute 13 front portions, make the past the place ahead perk gradually in back rest 3 lower ends, whole back rest 3 is namely around the positioning supporting point of bearing pin 5, go out toward hypsokinesis, and hypsokinesis needed space is offset by the front in-migration of seat 2; When back rest 3 hypsokinesis put in place, as Fig. 5.
