Description

A kind of adaptive adjustment ergonomics Lumbar
Technical field
It the utility model is related to office seating technical field, and in particular to a kind of adaptive adjustment human body work of office seating Learn Lumbar.
Background technology
Office chair is closely related as industrial products human lives, provides effectively support for people's work, meets daily Bend over one's desk working.The data provided according to TED research institutions, we daily will spent on chair 9.3 it is small when, for a long time Sitting brings the reduction of work efficiency, also causes a series of healthy hidden danger.According to German 1996 years according to statistics, 85% Pain in the back patient is due to caused by prolonged sit quietly.Therefore, suitable office chair size is one extremely important to long seated user Factor.
Ergonomics is gradually taken seriously in office chair design in recent years, such as patent 203897785U attempts to solve to pass Unite office chair size it is lack of standardization influence user's health the problem of.Patent 203897785U discloses a kind of office chair, is It is made of backrest, seat surface and chair leg;Seat surface lower end is connected with chair leg, and backrest bottom is hinged with seat surface by shaft;Lean on Back of the body lower end is equipped with Lumbar, and backrest middle and upper part is equipped with shoulder rest, and vibration headrest is additionally provided with backrest;Vibrating pillow is internally provided with sound Sound collector, vibrator and processor, seat surface both sides are equipped with handrail, and handrail is equipped with controller;Backrest also with scalable foot Pedal is connected.The utility model considerably increases the comfort level of office chair, prevents sitting band by setting Lumbar, shoulder rest etc. The fatigue come, by control of the controller to the angle of inclination of backrest, makes user so to be put with recumbency when lunch break Also the work efficiency in afternoon is improved while feelings of getting relaxed.
But the Lumbar of this integration does not ensure that adaptability, stability and comfort of the seat to different crowd, For the body shape or back curve of different crowd there are sizable difference, the factor such as height, weight, fat or thin can be right The body contour and back curve of people causes very big influence, forms entirely different body contour and back curve shape.It is existing These designs having can not fully meet these difference demands in fact.
Meanwhile existing Lumbar is generally deficient of adaptivity, cannot be provided all the time for different lumbar shapes suitable steady Fixed supporting point, it is even more impossible to provide the function of correcting sitting posture.
Utility model content
Based on this, it is necessary in view of the above-mentioned problems, a kind of adaptive adjustment ergonomics Lumbar is provided, including fixed setting The adaptive adjustment mechanism is fixed on to upset and movably forward and backward in the adaptive adjustment mechanism and Ke Ge on Seat support On Lumbar, the adaptive adjustment mechanism includes the support fixed seat being fixedly connected with Seat support and is fixed on the support Elastic component in fixed seat, the Lumbar include the Lumbar body with shaped form surface and are arranged on Lumbar body back Lumbar fixed seat, the elastic component are fixedly connected away from another end of support fixed seat with Lumbar fixed seat.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that the curve of the Lumbar body Lordosis, the curved arch curved surface swung back up and down in the middle part of vertical direction is in type surface and middle part indent, left and right are protracted in the horizontal direction The smooth surface that collectively forms of concave shaped curved surface.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that the Lumbar body includes waist Pad is leaned on by body fixed seat and the Lumbar being embedded in the Lumbar body fixed seat, the Lumbar fixed seat is arranged on Lumbar Body fixed seat leans on the back of pad relative to Lumbar.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that the Lumbar leans on pad and passes through Buckle structure is embedded in the Lumbar body fixed seat.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that the elastic component is spring, One end of the spring is fixed in support fixed seat, and the other end of spring is fixed in Lumbar fixed seat.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that the spring is arranged to two groups, One end of two groups of springs is separately fixed at the both ends of the support fixed seat, and the other end of two groups of springs is separately fixed at the waist By the both ends of fixed seat.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that the support fixed seat includes First fixinig plate and the two first annular clip pieces set on the first fixinig plate, the spring are fixed at support fixed seat Spring wire sequentially pass through described two first annular clip pieces, first fixinig plate is fixedly connected with Seat support.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that the support fixed seat includes Second fixinig plate and two the second annular snap hoop pieces set on the second fixinig plate, the spring are fixed at Lumbar fixed seat Spring wire sequentially pass through described two second annular snap hoop pieces, second fixinig plate is fixedly connected with Lumbar fixed seat.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that second fixinig plate is point Body structure, is separately positioned on the upper and lower ends of Lumbar fixed seat.
In adaptive adjustment ergonomics Lumbar according to the present utility model, it is preferable that the adaptive adjustment mechanism Setting two groups altogether with Lumbar, two groups of adaptive adjustment mechanisms are separately positioned on the left and right sides at Seat support waist location, and two Group Lumbar is arranged on corresponding adaptive adjustment mechanism by the elastic component of adaptive adjustment mechanism respectively.
Adaptive adjustment ergonomics Lumbar according to the present utility model, is provided by the curve and curved design of Lumbar Adaptability, stability and the comfort being bonded with user's human body waist, can provide for the lumbar shape of different users More docile support, will not produce uncomfortable sensation.By supporting the elastic mechanism of Lumbar, Lumbar is further enhanced Adaptivity,, can due to the deformation of elastic mechanism in the case where the different lumbar curve of user causes Lumbar stress difference With voluntarily adjustment Lumbar adapts it to lumbar curve well.By setting two Lumbars in left and right, for different lumbar shapes Properly stable supporting point can be provided.
Simultaneously as reaction force caused by elastic mechanism deformation can also act on Lumbar, in incorrect sitting-pose such as body Under crooked seat state, the reaction force that elastic construction feeds back to Lumbar can have that left and right is uneven, thus except front carries Outside the lumbar support force of confession, the reaction stress that user waist is applied with different directions is returned, promotes user to adjust sitting posture, Protect health.In the case where using two Lumbars in left and right, the difference meeting of the reaction stress provided respectively by left and right Lumbar It is more obvious and effective, enhance the performance of correcting sitting posture.
