Abstract

The purpose of this utility model is to provide a new type of seat for daily necessities for rest, office and car riding. Protruding to meet the needs of the buttocks at a certain distance in front of the backrest when people use the seat to rest. At the same time, the protrusion below the waist can make the backrest support the sacrum, bear part of the force, and reduce the burden on the lower back; at the same time, the protruding neck rest can be used to reduce the burden on the lower back, avoid neck muscle fatigue, and reduce shoulder and back pain; at the same time, the protruding headrest can be used to reduce the burden on the neck, making people more comfortable and conducive to rest, especially when driving, riding When people are forced to use the seat for a long time such as airplanes and ships, it can be more in line with people's physiological habits.

Description

A seat conforming to the physiological curvature of the spine

technical field

The utility model relates to a chair, in particular to a chair and a sofa characterized by structures such as foldable, with or without armrests, with or without legs, rotatable or fixed legs, and vertical adjustment.

Background technique

At present, the existing seats are mainly composed of a seat surface and a single-shaped backrest that is straight or concave. Although the improvement of the material improves the comfort of the seat, it does not conform to the characteristics of the physiological curvature of the human spine, resulting in Muscle tension and fatigue when people use the seat can even cause muscle and/or spinal injuries.

The utility model whose published application number is CN86206957 "Health Care Chair with Adjustable Backrest Height" is about a health care chair with adjustable backrest height, which is composed of backrest, seat board and chair frame. There are protrusions on the back of the chair. It can effectively support and protect the physiological depression in the scapular area of the human body, so as to prevent the thoracic spine from being compressed and displaced and the muscles of the back and paravertebral muscles strained by long-term sitting people, especially young people. The backrest and seat board of the chair are made of non-breaking plastic injection As a result, the chair frame is made of metal tube material. A similar effect can also be achieved by replacing the backrest of an ordinary chair with a utility model. This utility model has paid attention to the effective support and protection of the physiological depression in the scapular region of the human body, but has no effect on the protection of the physiological curvature of the human spine.

Therefore, people transform the seat, such as: the utility model whose open application number is 00235215. The wave-shaped backrest of the back makes three of the four physiological curvatures of the human body - lumbar curvature, chest curvature, cervical curvature or two physiological curvatures - the lumbar curvature and chest curvature can be maintained and maintained, and the corresponding parts The muscles get maximum relaxation and rest. However, when people use the seat to rest, the buttocks are usually at a certain distance in front of the backrest, and the sacral vertebrae and part of the lumbar vertebrae are in a suspended state, so the body cannot be effectively supported, causing muscle tension and fatigue.

Contents of the invention

The purpose of this utility model is to provide a seat for daily necessities for rest, office and travel, etc., which can maintain and protect the normal physiological curvature of the human spine, make people more comfortable, reduce the fatigue of the spine, and overcome Problems with currently used seats.

The seat of the utility model is made up of the single shape of the existing seat back in a straight line or concave back, and changes it to protrude forward below the waist, so as to adapt to the fact that the buttocks are often a certain distance in front of the backrest when people use the seat to rest. At the same time, the protrusion below the waist can make the backrest support the sacrum, bear part of the force, and reduce the burden on the lower back; at the same time, the protruding neck can be used to reduce the burden on the lower back, avoid neck muscle fatigue, and reduce shoulder and back pain. At the same time, the protruding headrest can be used to reduce the burden on the neck and be beneficial to rest, especially when the seat is forced to be used for a long time by car, plane, ship, etc., it can be more in line with people's physiological habits.

Therefore, seat of the present utility model is following several types:

1. There is a forward protruding part below the waist of the seat back. As shown in Figure 1.

2. The seat back can be composed of a forward protruding part below the waist and a protruding neck rest. as shown in picture 2.

3. The seat back can be composed of a forward protruding part below the waist, a protruding neck rest and a backward protruding headrest. As shown in Figure 3.

Compared with the prior art, the utility model is to change the conventional existing seat back into a straight line or concave shape, and change it to protrude forward below the waist, protruding neck rest and backward protruding headrest composed of seats. The contact area between the seat back and the back of the human body is increased, and the contact of individual joints and muscles is reduced, thereby sharing or reducing the burden on joints and muscles, avoiding damage to individual joints and muscles, and making it more comfortable to use. The present invention is illustrated below in conjunction with embodiment.
