Attached the chair to lumbar a rest cashion possessing an union and separation}

The present invention relates to a chair having a lumbar support auxiliary cushion having a detachable structure, and in particular, the auxiliary cushion is always placed in the right position so that there is no inconvenience in sitting. The present invention relates to a chair provided with a cushion for lumbar support having a detachable structure that can be easily and easily attached or detached from the back cushion unit to be selectively used to increase the merchandise and convenience, comfort, practicality, and productivity of the product.

Commonly used chairs are ergonomically designed to fit the body so that they can be seated in a more comfortable and convenient state for the seated person. It is composed of a back support cushion connected to form a right angle and the upper end is fixed to the center of the lower surface of the seat plate cushion portion so as to be stably seated and supported on the ground.

In order to provide the comfort and comfort of the seated person, armrests having a unique shape are placed on both sides of the seat cushion portion, and a head rest is provided to support the head on the upper backrest portion. And a plurality of casters (caster) is formed at a set interval at the bottom of the fixing support so as to move freely near the seat in a seated state is made to easily adjust the height of the chair.

In addition, the back cushion portion of the chair is not only to support any particular part of the body but to support most of the back and waist, and the joint so that it can be tilted at a rearward angle to give the desired support and comfort to the seated person. Formulas that are formulated are now in common use.

When the chair is seated, the lumbar spine (back) of the spine is bent inward while being seated in the lower back, and is not properly supported by the existing backrest cushion. The space is naturally formed. Because of this, when sitting for a long time, the curvature of the part is continued, stress and physical fatigue, the excessive load on the waist is increased. If this phenomenon persists for a long time, low back pain, which is a back pain, is caused, and when it worsens, spinal deformity is induced. In the growth period, there are serious problems that can cause fatal problems and harm health of the user's body.

As described above, with reference to the accompanying drawings, a number of conventional chairs having a lumbar support cushion in the back cushion portion are briefly described as follows.

First, the attached Figure 6a is installed so that the auxiliary backrest for the chair of the Korean Patent Publication No. 99-14638 protrudes to the lower front of the chair back (3) to elastically forward, backward to contact the lumbar spine. It is configured to support the lumbar region.

In addition, Figure 6b is attached to the back support for the chair of the domestic utility model registration application No. 89-521, the air inlet (1) having an air suction valve (1a) and the suction control cock (1b) is an air suction pipe (2) Is connected to the inner space (3a) through one side and is configured to attach to the back of the chair by inserting an air cushion (3) for attaching a pocket (5) attached to a plurality of magnets (4) on one side .

And, Figure 6c attached to the lumbar and lumbar support for the chair of the Korean Utility Model Publication No. 96-13219 is a pedestal (synthetic resin so that you can use against the corner of the vehicle or work chair (part where the seat and the back is connected) 1) injection molding, but the pedestal (1) is formed by separating the support plate (2) and the inclined control plate (3), the support plate (2) is a support bullet piece (5, 4 ') having locking portions (4, 4') on both sides of the rear surface , 5 '), and another support bullet piece 7, 7' having a bottom left and right locking protrusion 6, 6 'which forms the plurality of support bullet pieces 5, 5'. Protrudingly, the inclined control plate 3 forms a bent portion 8 so that one side is bent, and forms upper and lower left and right insertion portions 9 and 9 ', respectively, and has a predetermined thickness on the outer surface of the pedestal described above. The sponge 10 and the cover 11 were covered.

In addition, Figure 6d is attached to the domestic utility model registration application No. 89-15739 lumbar support for the chair is air blown in the air bag of the vinyl material attached to the air inlet (1), respectively The three substantially elliptical air bags 2, 2 'and 2' provided with the sphere 1 are connected to each other so as to be in a mutually coupled shape.

However, the conventional lumbar support for the chair or chair is limited to the user range because it is applied to all the seated persons regardless of the choice is fixedly mutually coupled to the auxiliary backrest to elastically actuated the back front lower back Due to its complex and complicated structure, manufacturing cost increases through a number of manufacturing processes, and Utility Model Registration Application No. 89-521 is detachable, but it is produced through a number of manufacturing processes, increasing costs and hassle. At the same time, there is a drawback of weak durability, the Utility Model No. 96-13219 is injection molded into a complex structure and shape in preparation for the load, the manufacturing cost is increased, as well as a separate fixing means is not provided for the user to sit or work If it is unclear, it may be uncomfortable and cumbersome to fall on the upper surface of the seat cushion by shaking. There is a drawback that the convenience and merchandise falls, and the utility model registration application No. 89-15739 injects air into the air through the air inlet, so it is cumbersome to use and there is no attachment means, so it is not fixed in place by the seated person's movement. There was a drawback that the ease of use, ease of use, and durability fell due to frequent departures.

In addition, the conventional lumbar support for chairs and chairs have a relatively complex structure and shape, the production is cumbersome and inconvenient due to the production is reduced productivity, cost increase, ease of convenience, etc., with durability and productability, reliability, etc. There were problems that could not satisfy the various needs of customers.

Therefore, the present invention has been devised to solve the fundamental problems of the prior art, and its purpose is that the auxiliary cushion is always attached and fixed at the back position of the back cushion so that there is no inconvenience in sitting, as well as the lumbar spine for the convenience of the user. The present invention provides a chair having a cushion for lumbar support having a detachable structure which can be easily and easily attached to or detached from the back cushion portion.
