Description

Improved chair back and neckrest structure

This creation is related to daily necessities, more specifically, it refers to a neckrest structure set on the back of the chair to support the neck and head of the user.

In daily life, many people sit in the seat for a long time, and because the head and neck are not supported, they will unconsciously appear shoulders backward and neck forward, and head drooping or lifting (most likely to occur when using a computer) ), the head is tilted to the left or right, causing the cervical spine to bend (most likely to occur when you are asleep in transportation) and other improper postures. The neck and shoulder muscles are stretched, contracted, and overtightened for a long time, resulting in blood vessel pressure in the head and neck Poor blood circulation to the brain can easily cause fatigue, inattention, dizziness, headaches and other problems. In more serious cases, the cervical spine and nerves will be injured, and there will be problems that are difficult to recover and correct.

The purpose of this creation is to provide an improved chair back and neckrest structure, which can be added to the chair back or car seat headrest to support the user’s neck and head and keep the neck and head in a normal posture , Reduce the support burden of the cervical spine, so that the cervical spine and shoulder muscles can relax naturally, and reduce the injury or discomfort caused by poor posture.

Technical features of this creation:

An improved chair back and neckrest structure, the neckrest structure is made of a supporting elastic material It is integrally formed and sewn a breathable cloth cover on the outside. It is characterized in that: the neckrest structure includes a curved rear support body and oppositely curved forwards from both sides of the rear support body. Extended two-sided support; the top and front of the rear support are defined as a pillow support, the middle area of the top gradually slopes downwards from back to front, and the front continues with the lowest point of the top and is rounded. The arc protrudes forward; the left area and the right area of the top protrude upward in an arc; the top surface of the side support body continues the left area and the right area of the rear support body and gradually changes from back to front Decline.

Preferably, the lower part of the rear support body extends downward to form a nape support part, and the front part of the nape support part continues the arc-shaped lower arc part of the pillow support part, and gradually changes from top to bottom to back. Slightly curved downward.

Preferably, the top surface of the front end area of the side support body is convex in an upward arc.

Preferably, the left and right sides of the back side of the rear support body are sewn to connect a buckle with an adjustable length, and the free ends of the two buckles are respectively connected with a male buckle and a female buckle.

Preferably, a storage bag is sewn on the breathable cloth cover on the outer sides of the two side supports, respectively, for storing the two buckle belts, the male buckle and the female buckle separately.

Preferably, the back side of the rear support body is sewn on the breathable cloth cover with a movable lap piece that can be flipped freely, and a hook-and-loop fastener is provided on the inner side of the lap piece.

The effect of this creation:

The user’s neck is located in the space enclosed by the rear support and the side support, the pillow support supports the user’s pillow, the nape support supports the user’s neck, and the rear support The left and right areas of the body are supported on the part of the user's occipital neck close to the ears. The overall curve and uneven changes of the rear support body make it fit the muscles of the pillow and neck of the user. The two-sided support body surrounds the user's neck and cheeks above the user's shoulders.

With the creation of the neckrest structure, the user's head and neck are adjusted in a normal posture, avoiding the problems of muscle shoulders, cervical spine and its nerve plexus caused by improper posture.

When resting in a sitting position, the user can tilt his head back slightly so that the pillow support and nape support can fully support the user’s pillow and neck and relax the neck and shoulder muscles; The arcs of the area and the right area bulge upward, so that the slightly backward head will not deflect to the left or right, and to avoid improper twisting of the neck and shoulder muscles and cervical spine.

When the user rests and relaxes the neck and shoulder muscles, it is more likely that the head and neck are tilted to the left or right. When the user is slightly tilted, the neck and cheeks will be supported by the corresponding side supports to prevent the user's head and Excessively skewed neck and shoulders.

The neckrest structure of this invention can be set on the top of the back of a general office chair by means of the lap piece.

The neckrest structure of the invention can be set on the headrest of the car seat by the buckle and the male buckle and the female buckle.

In order to facilitate the description of the central idea of the creation in the column of the above-mentioned new content, specific examples are used to express it. The various objects in the embodiment are drawn according to the proportion, size, deformation or displacement suitable for illustration, rather than drawn according to the proportion of the actual element, which will be described first. In the following description, the same and symmetrically arranged elements are denoted by the same numbers. In the following description, directional terms such as "front, back, left, right, up, down, inside, and outside" are used, which are expressed in accordance with the view direction and cannot be interpreted as a limitation of this creation.

As shown in Fig. 1 to Fig. 5, the neckrest structure of the present creation is integrally molded from a supportive elastic material, and a breathable cloth cover is sewn on the outside to cover the shape. The neckrest structure includes a curved arc-shaped rear support body 10 and two-sided support bodies 30 extending forwardly in curved arcs from both sides of the rear support body 10.

The top portion 11 and the front portion 12 of the rear support body 10 are defined as a pillow support portion 14. The middle area 111 of the top portion 11 gradually slopes downward from back to front. The front portion 12 continues the lowest point of the top portion 11 and follows the trend. The arc protrudes forward. The left area 112 and the right area 113 of the top portion 11 are convex upwardly. The lower part of the rear support body 10 extends downward into a nape support part 20. The front part 21 of the nape support part 20 is connected to the arc-shaped lower arc part of the pillow support part 14, and gradually changes downward from top to bottom. Oblique slightly curved. The back side 13 of the rear support body 10 is a vertical plane along the back side 22 of the nape support portion 20. A lap piece 15 is sewn on the breathable cloth cover of the back side 13 of the rear support body 10, and the lap piece 15 is connected to the back side 13 of the rear support body 10 by sewing at one end, and is capable of turning over and moving Flakes. The inner side of the lap piece 15 is provided with a hair surface (or hook surface) of the hook and loop fastener 151. The back side 13 of the rear support body 10 is sewn and connected to a buckle 16 with an adjustable length. Connect a male buckle 161 and a female buckle 162.

The top 31 of the two side supports 30 is respectively connected to the left area 112 and the right area 113 of the rear support 10 and gradually slopes downward from back to front. The front end area 32 of the second side support 30 close to its free end is an upward arc. Convex. The bottoms of the two side supports 30 are respectively connected to the left and right edges of the nape support portion 20. A storage bag 33 is sewn on the outer side of the two side supports 30 on the ventilating cloth cover, respectively, for storing the two buckle belts 16 and the male buckle 161 and the female buckle 162 that are separated.
