Detailed Description

The following description is presented to enable one of ordinary skill in the art to practice the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the utility model defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

Referring to fig. 1-2, the present utility model provides a technical solution: a roll support seat, comprising:

a seat 100, wherein the seat 100 is provided with an adjacent operation side 101 and a backrest side 102 of a human body;

the elastic support 200, the bottom of the elastic support 200 is connected with the operation side 101, the top surface of the elastic support 200 is provided with an arm bypass 203, and the elastic support 200 is inclined toward the outside of the opposite seat 100.

The roll support chair is characterized in that a user sits on the upper side of the chair seat 100, the user can lean on the inclined elastic support 200 in a roll state, the inclined elastic support 200 can provide a larger movement range for the elbows of the user in the roll state, and the body of the user can move within the elastic range of the elastic support 200, so that the load of the waist muscles of the user can be reduced.

In particular, the reason why the load of the lumbar muscle of the conventional seat user is large is that the conventional seat user can only support the elbows above the fixed armrest with limited movement, resulting in the user's lumbar region being maintained in a fixed position for a long period of time.

According to the novel seat, when a user is matched with the elastic support piece 200 to support the user sideways, the elastic support piece 200 can be matched with the inclined arm of the user, the arm and the elbow of the user can move on the contact surface of the elastic support piece 200, the elastic support piece 200 is elastically deformed under the influence of leaning action of the user, and the waist can keep a relatively comfortable movement range when the user leans sideways, so that the load of the waist muscle of the user is reduced.

It should be noted that, the recumbent support seat can be applied to the examination work of the sonographer, the ultrasound examination is the examination commonly used in clinic and with high usage, the workload of the sonographer is high, the sonographer often needs to keep a recumbent posture to the right front because of the operation instrument and examination content when working, the chair used in daily work cannot provide the corresponding lumbar support for the sonographer, the lumbar of the sonographer is damaged by muscle and bone due to long-term keeping of a posture, and the application of the recumbent support seat can avoid the above problems, and the inspector can operate the ultrasound probe to the patient by bypassing the top surface of the elastic support 200.

In order to facilitate the elastic support 200 to support the arm of the inspector operating the ultrasonic probe, the elastic support 200 is prevented from being uncomfortable due to partial pressing of the arm of the inspector, and further, the center of the arm bypass portion 203 is recessed downwards to form an arc shape.

The conventional armrest 600 is only suitable for elbow support, and its set height is low, and cannot meet the support requirement of the user for sideways work.

Further, the height of the top surface of the elastic support 200 corresponds to the height of the chest of the human body. The height of the top surface of the elastic support piece 200 is limited, so that the elastic support piece corresponds to the chest of a human body, the effect of supporting the upper half of the user is achieved, the support requirement of the user on the work of the user in a sideways manner is met, the elastic support piece is suitable for the movement of the upper limbs of the user in a certain range, and the conventional work of an inspector is not influenced.

Preferably, the top of the elastic support 200 is flush with the chest of the human body.

To enhance the elastic effect of the elastic support 200, the elastic support 200 can stably support the upper body of the user, and relieve the waist pressure when the user leans on the body, and in one embodiment of the present utility model, the elastic support 200 is curved in an arc shape toward one side of the human body. When the elastic supporting piece 200 which is bent to be arc-shaped is influenced by external force, the pressure of each arc-shaped part is dispersed, so that the external force can be buffered, and local fracture is avoided.

To ensure the sideways supporting effect of the elastic support 200, further, the curvature of the elastic support 200 is gradually increased from bottom to top.

By limiting the curvature of the elastic support 200 in the vertical direction, the curvature of the upper portion of the elastic support 200 is large, and the curvature is approximately overlapped with the horizontal plane, so that the human body in the lateral body state can be stably supported.

In one embodiment of the present utility model, the elastic support 200 includes:

the elastic support frame 201, the elastic support frame 201 comprises a support part 2011 and a connection part 2012, the seat 100, the connection part 2012 and the support part 2011 are sequentially connected from bottom to top, wherein the support part 2011 is bent to be arc-shaped towards one side of a human body, and the connection part 2012 is perpendicular to the seat 100;

the elastic mesh cloth 202, the elastic mesh cloth 202 covers the surface of the elastic support frame 201.

The elastic mesh 202 combines with the elastic support frame 201 to obtain a better elastic support effect, and the air permeability of the elastic mesh 202 can further improve the comfort of the body support, so that the vertical connecting portion 2012 and the seat 100 have higher connecting strength when being acted by external force in the vertical direction.

The elastic support 200 is curved to avoid affecting the upper body range of motion of the user above the seat 100.

Further, the resilient support 200 is projected vertically on a horizontal plane to avoid the vertical projection of the seat 100 on the horizontal plane. By limiting the vertical projection of the elastic support 200 and the vertical projection of the seat, the elastic support 200 is prevented from affecting the human movement in the area directly above the seat 100, thereby improving the use experience of the seat.

In order to facilitate adjustment of the elastic support 200 to a proper angle according to the habit of the user, and also to enable the elastic support 200 to act as a support point for the elbow joint of the user, the seat 100 is rotatably connected to the elastic support 200 to adjust the angle between the seat 100 and the elastic support 200, and the following embodiments are provided.
