Abstract

A manual adjustment pressure reducing work chair mainly comprises a front chair leg (3), a movable shaft (2), a seat frame (1) and a chair back (4), wherein the movable shaft (2) is arranged on the upper portion of the front chair leg (3), the seat frame (1) is connected to one end of the movable shaft (2), and the chair back (4) is provided with a plurality of nesting ports (5). The manual adjustment pressure reducing work chair is characterized in that A the movable shaft (2) is arranged between the front chair leg (3) and the seat frame (1), B the seat frame (1) is in a concave surface structure with a certain radian, and C one end of the seat frame (1) can be nested into the nesting ports (5) arranged on the chair back (4). As the seat frame (1) has the certain radian, the seat frame (1) can bear component force of the gravity of an upper half body in a horizontal direction while the bottom of a lumbar vertebra only bears component force of the gravity of the upper half body in a vertical direction, and the component force born by the bottom of the lumbar vertebra is smaller than all the gravity of the upper half body when a user sits on a horizontally arranged seat frame. The manual adjustment pressure reducing work chair relieves burden of the lumbar vertebra in work at a desk, and the nesting ports (5) on the chair back (4) meets different needs of people on the work chair.

Description

Manual adjustments decompression work chair

Technical field

The utility model relates to manual adjustments decompression work chair.

Background technology

At present, the seat mount structure of work chair does not have certain radian on the market.The horizontal sitting posture of people when bending over one's desk working makes the lumbar vertebrae bottom be subjected to above the waist all compressings of gravity, through long cumulative effect, the lumbar vertebrae bottom will be subjected to damage in various degree, be a stern challenge to health, also directly affect the normal rule of life of people.

The utility model content

The utility model is intended to address the above problem, and proposes manual adjustments decompression work chair.

In order to realize the object of the invention, intend adopting following technology:

The utility model is arranged on the movable axis on front chair leg top structurally by front chair leg, is connected the seat frame of movable axis one end and is provided with a plurality of nested mouthful chair back to constitute,

It is characterized in that:

A. between front chair leg and seat frame, be provided with movable axis.

B. the seat frame is the concave structure with certain radian.

C. seat frame one end can be nested in a plurality of nested mouthful that is provided with on the chair back.

The utility model characteristics compared with the prior art:

Because the seat frame of work chair of the present utility model structurally has certain radian, make the seat frame bear gravity component in the horizontal direction above the waist, and the component of gravity in the vertical direction is above the waist only born in the lumbar vertebrae bottom, reduced the size of the required whole gravity of the upper part of the body that bear on horizontally disposed seat frame, a plurality of nested mouth on the chair back provides the different demands of people to work chair.Compared with prior art, the utility model more reasonable contemplation directly alleviates the lumbar vertebrae burden of people when bending over one's desk working to the physiological structure of human body, simultaneously, provides the multiple choices of people to work chair.

Description of drawings

Fig. 2 has illustrated structure of the present utility model with the form of profile.

1: the seat frame; 2: movable axis; 3: front chair leg; 4: the chair back; 5: nested mouthful.

The specific embodiment

The utility model is structurally by front chair leg 3, be arranged on the movable axis 2 on front chair leg 3 tops, be connected the seat frame 1 of movable axis 2 one ends and be provided with a plurality of nested mouthful 5 chair back 4 and constitute, such architecture basics is very similar to prior art, seat frame 1 structurally has certain radian, reduce to oppress the strength in the lumbar vertebrae bottom, a plurality of nested mouthful 5 that is provided with on movable axis 2 and the chair back 4 can reach different height by adjustment seat frame 1.

The utility model in use, such structure can make the lumbar vertebrae bottom only bear the component of gravity in the vertical direction above the waist, reduced the size of the required whole gravity of the upper part of the body that bear on horizontally disposed seat frame, a plurality of nested mouths provide selection for the height of regulating present frame.Obviously, the use of manual adjustments decompression chair has reduced lumbar vertebrae because of long-term pressurized causes the hidden danger damaged, helps healthy.Satisfy people's demand to work chair under different situations, realize the maximum using of resource, economical and practical.

Size of the present utility model can be done corresponding adjustment according to the use crowd.

Claims (1)

1. manual adjustments decompression work chair mainly by front chair leg (3), is arranged on the movable axis (2) on front chair leg (3) top, the chair back (4) formation that is connected the seat frame (1) of movable axis (2) one ends and is provided with a plurality of nested mouthful (5),

It is characterized in that:

A. between front chair leg (3) and seat frame (1), be provided with movable axis (2);

B. seat frame (1) is the concave structure with certain radian;
