Existing recliner is in the majority with what design at vehicle-mounted fixed seat, be connected by elastic connecting device between backrest and seat support, rely on human body that backrest is applied a power backward, produce strain between the backrest seat support, to reach the purpose of adjusting the backrest elevation angle and make.This structural requirement elastic connecting device has very high support strength and stability, and the requirement of material and production technology all than higher, is unsuitable for promoting in common office or family expenses chair.The all adjustable chair of a kind of backrest and seat support is disclosed among the Chinese patent CN200720079196.3, its seat bottom is provided with the wedge shape support, all have latch before and after on the support, backrest back, seat support below is hinged with support bar respectively, the angle of regulating seat support and backrest by the screens of regulating support bar and support.Though this structure is simple, a large amount of latches are exposed to the bracing frame outside, and security remains to be considered; Support bar is long and load is bigger, and its strength of materials requires high, and it is big to implement difficulty.For backrest adjustable chair that CN200820148795.0 provided, its governor motion is too simple, and it is convenient inadequately to adjust, and still has very big room for improvement.
Summary of the invention:
The object of the present invention is to provide a kind of seat chair with adjustable backrest, this armchair structure is simple, easy to adjust, and the user can adjust angle between backrest and seat support according to self needs, to obtain comfortable sitting posture.
Based on above-mentioned purpose, the present invention has adopted following technical scheme: a kind of seat chair with adjustable backrest, comprise seat support, handrail and be hinged on the backrest of seat support back upper place, the backrest one or both sides are provided with alignment pin, the angle-adjusting mechanism that matches with alignment pin is installed in the handrail, described angle-adjusting mechanism is made up of draw-in groove plate, push rod and spring: the draw-in groove plate is articulated in handrail, has the draw-in groove of a series of fixing alignment pins on the draw-in groove plate; The push rod rear end is hinged on the draw-in groove plate, and the positive stop that is located on the handrail is passed at the middle part, and front end is provided with projection; Spring housing is contained on the push rod between projection and the positive stop.
Described draw-in groove plate curves " L " type, and an end extends upwardly and forms master arm, the other end stretches to the handrail rear and forms slave arm, is located at the corner of draw-in groove plate with the pin joint of handrail, and draw-in groove is opened on the slave arm; The push rod rear end is hinged on the upper end of master arm, and the push rod front end stretches out outside the handrail.
Have the alignment pin fenestra with draw-in groove plate corresponding position on the wall of handrail, for alignment pin plug-in mounting, slippage.
For ease of the application of force and for the operator provides comfort feel, pressure cap is equipped with in the end that push rod stretches out handrail, and pressure cap is buckled in the push rod end or is connected with the push rod end thread.
In technical scheme provided by the present invention, the draw-in groove plate rotates under the drive of push rod, realizes disengagement or fixing between draw-in groove and the alignment pin thus; The user need not to stand up, and only by just can easily adjusting the backrest elevation angle by the push rod that is pressed on the handrail, to obtain comfortable sitting posture, it is very convenient to operate.Be setting angle guiding mechanism in handrail, can upwards dig inner chamber, also handrail can be made by the multi-disc housing and fasten the pin-connected panel handrail that forms from the below of whole handrail.Angle-adjusting mechanism is inlaid in the handrail, can improve the security and the aesthetics of seat in members such as protection card frid, push rod, spring.The present invention has only carried out bigger change on handrail for traditional Chinese chair, can not produce substantial influence to the production technology of seat, and production cost is easy to control; Compare with other seat chair with adjustable backrest, it is simple in structure, be convenient to processing, suits very much to promote in family expenses or office seating.
