Benefits of technology
[0008] The present invention is achieved in view of such circumstances, and has an object to provide a seating mechanism and a chair that can prevent and correct various distortions or disorders in the body more effectively, generally, and conveniently than conventional ones.
[0028] A chair according to the present invention includes the seating mechanism according to the present invention and effectively functions, and includes the seating mechanism according to the present invention and a leg on which the seating mechanism is placed.
Problems solved by technology
If the user sits at a desk in such a posture, the user stoops with his / her back bent and the abdomen compressed, and supports the forward-tilted head with muscles of the neck and shoulders, which often causes stiff shoulders.
Long hours of deskwork in the stooping posture causes fatigue to build, and the body requires parasympathetic nerve activity, while the deskwork requires sympathetic nerve activity, which needs to forcedly strain sympathetic nerve.
This unbalances the sympathetic nerve activity and the parasympathetic nerve activity, causing an increase in stress (excessive strain of sympathetic nerve).

A seating mechanism according to the present invention includes: a support provided on a holder; a seat plate provided pivotably in a substantially vertical direction around the support; and two control portions that are provided with the support therebetween, and apply, when a vertical force is applied to the seat plate, a resisting force against the vertical force to the seat plate. A chair according to the present invention includes the seating mechanism placed on a leg.
Description
TECHNICAL FIELD [0001] The present invention relates to a seating mechanism and a chair. BACKGROUND ART [0002] A general chair has a structure intended for easy seating. For a chair having a backrest, for example, a user tends to sit thereon with his / her back in contact with the backrest. In this case, the user tends to sit with the center of gravity shifted backward. If the user sits at a desk in such a posture, the user stoops with his / her back bent and the abdomen compressed, and supports the forward-tilted head with muscles of the neck and shoulders, which often causes stiff shoulders. [0003] It is known that good autonomic nerve activity is maintained by balanced activities of sympathetic nerve and parasympathetic nerve. Long hours of deskwork in the stooping posture causes fatigue to build, and the body requires parasympathetic nerve activity, while the deskwork requires sympathetic nerve activity, which needs to forcedly strain sympathetic nerve. This unbalances the sympathet...
