Description

The chair made of multi-ply (glued wood), beech wood screws and beech wood pegs is designed so that the backrest 16 or main foot 1 is provided with pins 22 and a movable support 2 with holes 22 at 19 stored from a 90 ° sitting position to 45 ° can be put behind.

This setting allows the pressure to be lifted using the gravity of the Body weight on the vertebrae are increased or reduced.

The seat 4 , provided with a spoon-like extension 20 and rows of holes 3 , pin 21 as the main position, can also be adjusted in height by the pin 9 .

The seat cushion can be positioned towards the body by removing the pins 8 and unscrewing the wood screw 6 or by removing the pins 7 and unscrewing the wood screw 5 away from the body. With which the angle of the legs to the back can be determined.

The seat cushion has a recess for the coccyx in the top view, so that it remains depressurized.

The front adjustable by wood screws and mounted by a pin 11 wooden axis 16 is used for rough back adjustment (only required for strong rounded backs).

The forward adjustable, running in a mortise and held by clamping screws 10 slider 23 are divided so that slider 23 _a for the lumbar spine, slider 23 _b for the thoracic spine and slider 23 _{c are} responsible for the cervical spine.

You can closely follow the physiological vibration of your back be approached.

The pivot axes (wooden plates 18 ) mounted on the slides 23 by means of pins 15 can also be turned forward by wooden screws 17 (knotted with a wooden nut 24 ) and thus adapted to the physiological vibration.

On the wooden boards 18 are either specific to the user by plaster cast molded and nachgefräßte in wooden pegs supports 12/13/14, which are only as wide as the spine, or pads, which are provided with an adaptive filling that the located Adjust swirls.

State of the art US 4,359,245 Folding chair document 1

With this chair, the user can adjust the Make any shape of his back.

This will move from the user's back through the large sub support surface taken a little pressure load and this guarantees often a more comfortable sitting position than with conventional chairs.

disadvantage

The support area can not be the physiological Adjust the conditions of the back, since this is not compatible is adjustable and only conditionally due to the larger support surface Represents relief.

WO 98,58,566 A1 Adjustable back padding document 2

This back cushion serves to support the lower back and also offers relief in the wide contact area Lower back area.

disadvantage

This cushion is not specially designed and gives to the spine Even with strong spinal twists after d. H. also at Poor posture.

task

This chair is variable on the whole due to its individual components Adjust the surface, and thus the support surface of the chair Can be adjusted exactly to the physiological vibration of the spine.

Since the spine is divided into different sections: LWS 12 / BWS 13 and HWS 14 and the individual vertebral bodies converge, the individual adjustable elements (support width only as wide as the spine) of the chair can be approached to the respective vertebral segments of the user, that the respective segments rest physiologically and are thus relieved of gravity through the pressure distribution of the posterior spinous processes, transverse processes of the capsular ligament apparatus of the individual vertebral bodies.

Nozireceptors are due to the physiological vibration of the Spine and the pressure load on the posterior spinous processes above afferent and efferent switching S. down in the respective segments set. The individual muscle groups (autochromic Muscles) that are innervated in their pathways via the efferent pathways Tension tone reduced.

And there is relief.

In addition, the intervertebral discs of the individual segments can load and refill with liquid through diffusion because the vertebrae column is in its physiological vibration. extension of Foramula intervertebralia and therefore more space for the spinal nerves.

embodiment

The user takes a position on the spine relief chair, in the basic position Fig. 1.

Then the seat 4 is pivoted up or down by pivoting the extension 20 , FIG. 3, so that the cervical center of the user comes to rest on the center of the slide 23 _c . FIG. 1.

By removing the pins 7 or 8 and turning up the screws 5 or 6 , the seat cushion 4 in the inclination Fig. 7 and 8 to the backrest can be adjusted so that the thighs or legs are approximately at a 90 ° angle to the back.

If the physiological adaptation of the vertebrae stays 12/13/14 through start-up and clamping of the slider 23 by the screws 10 to the points cervical spine / thoracic spine / and lumbar spine and by pre-rotating the pivot axes 18 by pre-turning of the screw 17 and lock with the nuts 24 Fig. 5th

The backrest 1 and 16 can be moved up to 45 ° to the rear by pivoting the support 2 and securing it with the pin 9. FIG. 4.
