Description

Seats that adapt to the human body

technical field

The model relates to a seat adapted to the human body, which belongs to the technical field of household articles.

Background technique

Seats are essential daily necessities for people to use. The backrests of many seats are curved to fit the curve of the human body. However, each person's body shape is different, and the difference is quite large. Seats on the market cannot adapt to every user.

In addition, even if the human body bionics seat is applied to adapt to the curve of the human body, due to sitting for a long time, the human body will be tired and bend over unconsciously, which cannot achieve the expected effect.

Contents of the invention

The technical problem to be solved by the utility model is to provide a seat adapted to the human body, which can adapt to the physiological curves of different body types and prevent users from bending over.

The technical solution adopted in the utility model is: a seat adapted to the human body, including a backrest, left and right brackets, left and right frame arms, support rods, and slide rails, wherein: the slide rail is arranged inside the backrest, and the left fixing part passes through the slide rail. The left bracket is fixed, and the left bracket moves horizontally and vertically on the slide rail; the right bracket is fixed on the slide rail through the right fixing piece, and the right bracket moves horizontally and vertically on the slide rail; the left bracket is connected to the arm of the left frame, The right bracket is connected with the right frame arm bar; the backrest is provided with multiple sets of extended and retracted support rods to dynamically adapt to the physiological curve of the human body; the control bar is fixed on the armrest of the seat and connected with the positioning bar through a lever.

The left and right frame arms are divided into two parts, and the hinged front ends in the middle are foldable and fixed.

The left and right frame arms are respectively connected to the left and right brackets in a hinged manner, and the left and right frame arms can be folded upward by 90 degrees.

Each of the multiple sets of support rods is connected to its corresponding connecting rod 4 , and the connecting rod 4 is connected to the vertical wall 7 through a spring 6 .

The side of the connecting rod is provided with continuous concave holes, all the connecting rods of the multiple sets of support rods are on a vertical plane, and the positioning rod moves to the concave holes to fix all the connecting rods at the same time.

Described left and right frame arm rods, support rod outer package decorative soft material.

The beneficial technical effect obtained by the utility model is that the spacing between the left and right brackets is adjusted horizontally and vertically on the slide rail by using the fixing parts, and the human bodies of different sizes are supported from the underarms to maintain an upright sitting posture; The retracted support rod adapts to the physiological curves of the human spine of different sizes, and fits perfectly to form effective support.

In the figure: 1_1 left frame arm rod, 1_2 right frame arm rod, 2_1 left bracket, 2_2 right bracket, 3 support rod, 4 connecting rod, 5 recessed hole, 6 spring, 7 vertical wall, 8 positioning rod, 9_1 left fixing piece , 9_2 right fixture, 10 control rods, 11 slide rails.

Detailed ways

Further description below in conjunction with accompanying drawings.

The innovations of the utility model are as follows: firstly, by horizontally adjusting and vertically adjusting the distance between the left and right brackets, the human body of different body types is supported from the armpit to maintain an upright sitting posture. The second is: the backrest is equipped with multiple sets of dynamically extending and retracting support rods to adapt to the physiological curves of the human spine of different body types. The length of the support rods is adjusted by springs to perfectly fit different body shapes to form effective support.

Embodiment 1: the seat that adapts to human body, comprises backrest, left and right supports, left and right frame arm bar, support bar, slide rail, described backrest interior arranges slide rail 11, fixes left support 2_1 left support by left fixture 9_1 on slide rail Move horizontally and vertically on the slide rail; fix the right bracket 2_2 on the slide rail through the right fixture 9_2. The right bracket moves horizontally and vertically on the slide rail; Connect the right arm bar 1_2 at the top; adjust the horizontal and vertical positions of the left and right brackets according to the body shape of different users to ensure that the left arm bar and the right arm bar support the user from the user's armpit, preventing the user from bending unconsciously when sitting for a long time waist. The left and right arms are divided into two parts, and the front end is hinged in the middle. The front end can be folded and fixed. The front ends of the left and right arms can be folded up 90 degrees and fixed, so that the human body can be fixed on the shoulders to prevent forward leaning.

The backrest is provided with multiple sets of protruding and retracting support rods 3 to dynamically adapt to the physiological curve of the human body; The side of described connecting rod 4 is provided with continuous recessed hole 5, and all connecting rods of multiple groups of support rods are on a vertical plane, and control rod 10 is fixed on the seat armrest and links to each other by lever and positioning rod 8. When using, the user first moves the control lever to make the positioning lever leave the concave hole, and the spring resets. After the user sits upright, adjust the left and right arm levers first. The physiological curve of the body makes the spring contract to different degrees, and the user moves the control lever through the lever to make The positioning rod 8 moves to the concave hole 5 and fixes all the connecting rods to play a fixed supporting role. At this time, the multiple sets of support rods adapt to the physiological curves of users of different body types and fit perfectly, and the positioning rods offset the elastic support effect of the springs.

The rear ends of the left and right frame arms are respectively connected to the left and right brackets in a hinged manner, and the left and right frame arms can be folded upward by 90 degrees. It can be folded and stored when not in use, saving space. The left and right frame arm bars and support rods are covered with decorative soft materials such as outer cloth and inner layer sponge to play an aesthetic and comfortable role.
