Description

A chair with a tilted seat {A chair on which seats are tilted}

The present invention relates to a chair in which the seat plate is tilted, and in more detail, the seat plate of the chair can be inclined at a certain angle according to the user's seating posture, so that the user can always sit in a posture with the lumbar spine upright. It relates to a chair in which the seat plate is tilted, which was developed in order to correct and to perform lower back movements as needed.

In general, a chair is a tool for a person to sit, and is composed of a seat plate that supports the user's buttocks, a back support that can lean on the user's back, and a frame that connects and supports the seat plate and the back support.

Unlike the past, when there were many external activities, these chairs have been continuously increasing the time used for office, leisure, and learning due to recent industrial development and changes in lifestyle. However, conventional chairs are designed to only support a part of the user's body with the seat plate and the back fixed, so it is difficult for patients or the elderly with abnormalities in the back or knee joints who are uncomfortable sitting on a chair or taking actions. There is a group.

Therefore, in recent years, functional chairs have been proposed that consider not only the shape of the chair, but also the functional aspect so that patients or the elderly with abnormalities in the back or knee joint can use. In particular, a chair for knee joint patients in which the rear of the seat plate is raised and lowered has been proposed to reduce the burden on the knee joint when the user sits or rises.

As an example, in the case of the'chair for preventing concentrated pressure on the knee joint' of Korean Patent Publication No. 10-1279076 (2013 06 20), a support frame for supporting a seat plate for a user's seating, and a support frame at a right angle to the support frame In a chair for knee joint patients comprising a backrest frame for supporting a backrest to be disposed, and armrests and armrest frames formed to the left and right of the seat plate, one end of the armrest frame protrudes inwardly across one side of the support frame It is formed so that the seat plate is always obliquely supported before seating by an elastic force between the seat plate and the support frame, and when standing after seating, the seat plate is easily rotated to its original position, so as to easily assist the standing of chair users such as knee joint patients, It comprises a bracket and an elastic body, the elastic body is fitted to the protruding one end of the armrest frame, one end of the elastic body is coupled to be movable to the bracket, the other end includes a rotation driving means fixedly coupled to the support frame.

However, in the prior art, when the user stands up from a sitting position, the rear end of the seat plate is raised only by holding and pressing the armrest frame, so the patient or the elderly with discomfort cannot use the seat plate, and the rear end of the seat plate is raised by the elastic body. There is a limitation in assisting an overweight user to stand up, and there is a problem in that the ascending speed of the rear end of the seat plate cannot be adjusted according to the user's weight.

Conversely, when the rod of the actuator 22a disposed on the left descends and the rod of the actuator 22b disposed on the right rises, the left side of the seat plate 3 As the end portion descends and the right end portion rises, the seat plate is inclined (d), so that the seat plate can be rotated left and right in which the seat plate is inclined in the left and right direction.

In addition, when the seat plate is inclined forward or backward (a,b), the rod of one actuator is raised or lowered, or the seat plate is inclined to the left or right (c,d), both actuators 22a, 22b When the rod of) rises or falls at the same time, the seat plate 3 can be rotated in a diagonal direction.

Accordingly, according to the present invention, the seat plate 3 is installed so that it can be inclined freely in the front-rear direction and the left-right direction by the rotating part 10, and the driving part 20 supports the seat plate 3 in the front-rear direction and the left-right side. As it can be operated so as to be inclined in the direction, it is possible to perform an exercise that increases flexibility, muscle strength, and stability of the spinal joint by stimulating the back and spine of the user seated in the seat.

In addition, as shown in FIG. 7, it is preferable to provide a plurality of sensor units 50 on the seat plate so that the position of the hips of the user seated on the seat plate can be detected.

That is, a plurality of the sensor units 50 are arranged side by side so that each sensor unit senses the weight of the occupant and transmits it to the control unit 40, and the control unit 40 is based on the position of the rotating unit 10 By comparing the load detected by the sensor unit installed in the front and the load detected by the sensor unit installed at the rear, it is possible to detect whether the user is seated lean to the front or rear. Likewise, the load detected by the sensor unit installed on the left and the load installed on the right side By comparing the load sensed by the sensor unit, it detects whether the seat is skewed left or right.

Therefore, when the user is seated with the rotation unit 10 as the center of the seat, the control unit 40 receives and senses a signal from the sensor unit 50, and the control unit 40 detects the actuator 22a, 22b) is operated, and the seat plate 3 is tilted for a predetermined time and then returned to its original state, and the user's posture can be corrected by repeatedly performing this so that the hips are located in the center of the seat plate.

In addition, as shown in FIG. 8, it is preferable that a remote control unit 60 for remotely operating and operating the actuators 22a and 22b by a user through wired or wireless communication is provided.

In addition, the remote control unit 60 includes a power switch 61 for opening and closing the power of the power supply unit 30, a front-rear rotation in which the seat plate is inclined in a front-rear direction, a left-right rotation inclined in a left-right direction, and the front-rear rotation. It is preferable to include a manual operation switch 62 for controlling the complex rotation and the left and right rotations operate at the same time.

Accordingly, the user seated on the seat plate 3 can manually tilt the seat plate and adjust it according to the body shape by arbitrarily manipulating the actuators 22a and 22b of the driving unit for driving the seat plate.
