Description

Backrest with cushion

Technical Field

The utility model relates to a back field especially relates to a take back of cushion.

Background

With the progress of society, more and more occupations of sitting on a chair for working for a long time appear, and the sedentary life style brings many health problems, and diseases such as cervical vertebra, back and waist can be accumulated for a long time. At present, a plurality of functional backrests are available on the market, which can support the thoracic region, the lumbar region and the muscle tissues around the thoracic region, the lumbar region, so as to relieve the pressure of the vertebral joints, the intervertebral discs and the related muscle tissues of the thoracic region and the lumbar region, and limit the mobility of the back and the lumbar region, so as to maintain the normal radian of the thoracic region and the lumbar region. Conventional backrests generally provide only a supportive effect, enhancing comfort for the user during prolonged sitting. However, when the body is gradually used to a habit, the user can discard the habit after the habit is not comfortable, which causes resource waste.

In order to increase the effect of physical therapy, massage chairs, massage instruments and other devices are also available in the market to perform stimulation massage on key acupuncture points of a human body. However, the user does not always need the massage function, and if the massage device is fixed to the seat back, the long-term pressing may easily cause the damage of the massage device, which may reduce the life span of the massage device. At this time, the user can only use the backrest as a common backrest, which seriously affects the efficacy of the product.

SUMMERY OF THE UTILITY MODEL

Based on this, the utility model aims to provide a take back of cushion realizes the conversion of back multiple functions through replacing the second backup pad, improves life under the circumstances that satisfies multiple functions, has simple structure, convenient operation's advantage.

A backrest with a cushion, comprising:

the back plate is characterized in that the radian of the inner side of the central longitudinal section of the back plate in the vertical direction is correspondingly consistent with the radians of thoracic vertebrae and lumbar vertebrae of a human body, the back plate comprises a first supporting plate, a second supporting plate and a connecting assembly, the first supporting plate and the second supporting plate are fixed through the connecting assembly, the first supporting plate is provided with a protruding massage body, and the positions of the massage body, which are arranged on the inner side surface and correspond to the two sides of the thoracic vertebrae and the lumbar vertebrae, are uniformly distributed in the vertical direction;

support members made of metal or a rigid plasticized material and installed on the rear surface of the back plate in a vertical direction, respectively, both ends of each of the support members being fixed to the back plate, respectively;

the radian of the cushion is consistent with that of the buttocks of a human body and is rotationally connected with the second supporting plate.

A take back of cushion, the accessible replaces the conversion that the second backup pad realized the multiple function of back, satisfies the life that improves the back under the circumstances of multiple function. The supporting component can be conveniently moved, and plays a supporting role for the backrest. Simultaneously, the cushion can rotate after the use and fold, is convenient for follow-up accomodating.

Furthermore, a splicing groove is formed in the bottom of the first supporting plate, and the size of the splicing groove is matched with the appearance of the second supporting plate, so that the second supporting plate is spliced with the first supporting plate. Because the region of massage concentrates on the centre, the massage effect that both sides played is very little, consequently setting up of concatenation groove makes first backup pad partly surround the second backup pad, can replace to the massage region on the one hand, and on the other hand realizes the concatenation function, makes the replacement operation more simple and convenient.

Further, coupling assembling includes fixing base and inserted block, the fixing base is fixed on the splice groove, the slot has been seted up on the fixing base, the inserted block is fixed in the second backup pad, its size with the size looks adaptation of slot, and the cooperation of pegging graft between the two. The insertion matching can realize quick replacement, and further makes the replacement operation simpler and more convenient.

Further, the fixing base with first backup pad is the integrated into one piece structure, the inserted block with the second backup pad is the integrated into one piece structure, a plurality of through-holes have been seted up to the inside of inserted block, a plurality of screw holes have been seted up to the outer wall of fixing base, just threaded hole female connection has locking bolt. The threaded connection can enhance the stability of the connection between the first support plate and the second support plate, and prevent the first support plate and the second support plate from being separated due to the pressure of the body of a user.

Furthermore, the fixing seat is arranged on the splicing groove in a surrounding mode, and the depth of the inserting groove on the bottom side of the splicing groove is larger than the size of the two side portions of the splicing groove. Because the backrest can be pressed by the upper half of the user in the using process, the matching degree of the first supporting plate and the second supporting plate in the folding direction is increased, the connection stability is enhanced, and the separation is prevented.

Further, the fixing seat is only arranged on the bottom edge of the splicing groove. Can only carry out the cooperation restriction in this folding direction, reduce the restriction in the concatenation in-process size, make the concatenation process more simple and convenient.

Furthermore, a protruding massage body or an electrotherapy massage component is arranged on the second support plate, the massage body or the electrotherapy massage component corresponds to a common mode and an electrotherapy massage mode, and the switching between the modes is realized by replacing the second support plate; the massage bodies are arranged on the inner side surface and are uniformly distributed along the vertical direction at positions corresponding to the two sides of the thoracic vertebra and the lumbar vertebra; the electrotherapy massage component comprises at least four massage pads and an electrotherapy signal generating device, the massage pads are detachably connected with the second support plate, the massage pads are made of conductive fibers and protrude towards the human body, and the massage pads are respectively and electrically connected with the electrotherapy signal generating device through electric wires. The replacement of the mode can meet different requirements of the user on the function of the backrest at different times, and the physiotherapy effect is improved.

Further, a plurality of anti-skidding rubber mats are adhered to the bottom of the cushion. The antiskid rubber mat can prevent the sliding between the cushion and the office chair, and avoid the injury to users.

Further, the back of the back plate is also provided with a fixing belt which is made of elastic materials or is of a buckle type structure. The fixing band can fix the backrest on the office chair, so as to avoid collision with the cushion after falling.

Furthermore, a plurality of air holes are uniformly distributed on the left wing, the right wing, the middle part and the cushion of the back plate. The bleeder vent strengthens this utility model's gas permeability, prevents the uncomfortable sense because of sitting overheated leading to for a long time.

For a better understanding and an implementation, the present invention is described in detail below with reference to the accompanying drawings.
