The CPU 110 is also a means for controlling the massage range so as to change the massage range according to the change of the posture of the user, that is, the position of the seat 10 and / or the back 20 of the massage chair. .

The first sensor 120 is a means for detecting a change in the posture of the user seated on the massage chair, that is, a change in the position of the seat 10 and / or the back 20 of the massage chair.

The first sensor 120 is installed at a predetermined portion of the massage chair, and is, for example, a means for detecting a distance away from the sensor depending on the degree of lying down when the backrest 20 is laid down.

The first sensor 120 may be, for example, a sensor for measuring a distance, and distance data provided based on a case in which the backrest unit 20 is in a normal position to move away from or close to the sensor of the backrest unit 20. The distance between the backrest 20 and the nearness of the back 20 is determined, and the position of the massage roll 40 and the massage position for the user can be changed according to the determination result.

In the above description, the distance from or near to the first sensor 120 of the backrest 20 may be determined as, for example, a section divided for each predetermined value. That is, for example, it may be applied to a change in the position of the massage roll 40, a change in the massage position, and a range by processing data such as moving away from or close to a 5 centimeter section.

Meanwhile, the first sensor 120 may be a means for detecting an angle formed between the seating unit 10 and the backrest 20. In this case, the first sensor 120 also compares the distance from or near the sensor of the backrest 20 to the angle data provided based on the case where the backrest 20 is in a normal position. Determination of the distance or nearness, the position of the massage roll 40 and the massage position and range for the user can be changed according to the determination result.

The second sensor 130 is a means for detecting the body shape of the user seated on the massage chair. Here, the body shape of the user, as mentioned above, can be seen in the length and width of the user's shoulders to the thighs, etc., the seat 10, the back 20 and the footrest 30 of the massage chair The overall length of the user may be managed as reference length data, and the body shape of the user may be analyzed by quantifying how close the length of the user is to the reference length data.

The user's body shape analyzed as above is used to determine the massage position and range.

The motor driver 140 may change the position of the massage roll 40 and massage position and / or massage according to the posture and / or body shape of the user sensed by the first sensor 120 and / or the second sensor 130. It is a means for driving the motor 141 by receiving the control signal of the CPU 110 to change the range.

The motor 141, the shaft of which may be connected to the massage roll 40, is rotated in a predetermined speed and a predetermined direction by the control signal of the motor driving unit 140 and the position change of the massage roll 40 determined above and Massage means to massage the user by location and / or massage range. For example, the predetermined direction may be in the forward direction when the massage is performed from the user's shoulder toward the thigh and in the reverse direction when the massage is performed while moving up from the user's thigh to the shoulder.

On the other hand, the motor 141 is rotated for the vertical movement of the massage chair body so that the entire motor frame 45, the massage roll 40 is installed, the position of the massage roll 40 and the massage position and range for the user is changed. It may be driven, or may be rotationally driven so that the massage to the user is made by interlocking the massage roll 40 in place in the position change and massage position and range of the massage roll 40 is determined.

When the massage chair is driven to move up and down, the gear 47 installed in the motor frame 45 by the rotational drive of the motor 141 is implemented by operating with respect to the rail 50, and the massage in a fixed position. When driven for, it may be implemented that the massage roll 40 is operated to interlock in the same direction irrespective of the gear 47 and the rail 50.

The gear 47 installed in the motor frame 45 may be connected to the shaft of the motor 141 to be interlocked according to the rotational drive of the motor 141.

Massage roll 40 is connected to the axis of the motor 141 is a means for massage the user. Massage roll 40 is also rotated in conjunction with the forward and reverse rotation of the motor 141 to massage the user. However, it is not limited thereto. For example, the massage roll 40 may be configured not to be connected to the shaft of the motor 141, in which case the automatic rotation of the massage roll 40 is impossible, for example, the motor frame 45 is a rail By moving up and down along 50, rotation can be driven irregularly by the force.

On the other hand, the frame 45 is configured to include the motor 141, the gear 47 is configured, the gear 47 is a rail (50) formed from the shoulder portion of the massage chair to the thigh portion When the ride moves, massage roll 40 is also linked to this can be made to massage the user.

In another embodiment, the motor 141 may be driven to rotate in the forward or reverse direction so that the backrest 20 is automatically laid down or raised. That is, the automatic lay-up or rise of the backrest part 20 by the motor 141 is such that the gear 47 provided in the motor frame 45 is rotated in the forward and reverse directions of the motor 141 to the rail 50. It can be done by riding up and down.

The massage position / range analyzer 150 analyzes the massage position and / or the massage range for the user to be changed according to the posture of the user sensed by the first sensor 120 and the second sensor 130. Means.

The user body analyzer 160 is a means for analyzing the body shape of the user sensed by the second sensor 130.

In the massage chair of the present invention configured as described above, a control for changing the massage position according to the change of the posture of the user will be described.

First, when the user maintains the initial posture, that is, when the backrest 20 of the massage chair is not lying down and maintains the initial state, the massage roll 40 maintains the state positioned on the back of the user. .

Therefore, when the massage chair is operated, the CPU 110 transmits a motor rotation driving signal to the motor driver 140 so that the motor 141 rotates in the forward or reverse direction, and at the same time, the massage roll 40 also moves in the forward or reverse direction. Rotate to massage the user's back.

In this state, when the backrest part 20 is inclined at an initial position (delayed), that is, away from the first sensor 120 by a predetermined distance, the first sensor 120 detects this and sends it to the CPU 110. The CPU 110 changes the position of the massage roll 40 by substituting a predetermined distance away from the back of the user.

The position change of the massage roll 40 is that the backrest 20 is moved away from the first sensor 120, the massage roll 40 should also be moved further away from the initial position, that is, the backrest 20 above. Since it means, it is implemented by moving the position of the massage roll 40 to the upper back portion 20 based on this.

In more detail, when the massage chair is in an initial state, the backrest 20 forms an angle of about 90 ° or more than a predetermined angle with respect to the seating part 10, for example, about 100 °. Therefore, for example, since the upper end of the backrest 20 and the first sensor 120 are positioned almost diagonally, the distance between the first sensor 120 and the backrest 20 in this state will be the shortest distance. Therefore, if the backrest 20 is further laid down in this state, the distance between the first sensor 120 and the backrest 20 becomes further, so that the position of the massage roll 40 may be changed to massage the back of the user who is in the initial state. You have to change it farther.

The position change of the massage roll 40 is made possible by the gear 47 comprised in the motor frame 45 moving on the rail 50 as mentioned above.

After performing massage on the back of the user in such a state, if the user wants to return to the original state again, since the backrest part 20 is raised again, the distance between the first sensor 120 and the backrest part 20 becomes short, As a result, the massage roll 40 is also returned to its original position.

Next, a description will be given of the control in which the massage position initially set is changed in accordance with the posture of the user. This operation is such that when the user's posture is changed, the massage position is changed to the hips or thighs of the user even if massage is performed on the back of the first user.

First, when the backrest 20 is inclined by a predetermined angle, that is, when the backrest 20 is laid down by a predetermined angle, it means that the distance between the first sensor 120 and the backrest 20 becomes farther as described above. 120 detects this and inputs it to the CPU 110.

Therefore, the CPU 110 determines that the backrest unit 20 is inclined at a predetermined angle by processing the detection signal of the first sensor 120, and transmits a motor driving signal to the motor driving unit 140 so that the motor 141 is predetermined. Drive in the direction of rotation. Here, the predetermined direction refers to a direction in which the massage roll 40 moves down the user's body such as a hip or thigh.

That is, in accordance with the rotational drive of the motor 141, the motor frame 45 is moved to the hips or thighs of the user by the rail 50, and maintains a stop state. In this state, the massage roll 40 is rotated and driven. Massage your hips or thighs.

After performing massage on the hips or thighs of the user in such a state, if the user wants to return to the original state again, the backrest part 20 is rebuilt, so the distance between the first sensor 120 and the backrest part 20 is short. The massage roll 40 is thus returned to its original position.

Next, the control based on the user's body type analysis will be described.

The body shape of the user is detected by the second sensor 130.

The body shape of the user sensed by the second sensor 130 is input to the CPU 110 and processed, and the processed body shape data is compared with the size of the massage chair, that is, the size data from the back portion to the footrest portion.

According to the comparison result, the CPU 110 determines how much the user's body shape occupies within the range from the backrest portion to the footrest portion of the initially set massage chair, and determines the massage range. That is, the movement range of the massage roll 40 is determined.

When the movement range of the massage roll 40 is determined, the CPU 110 transmits a motor driving signal to the motor driving unit 140 to drive the motor 141 to forward and reverse rotation at predetermined time intervals. That is, the massage roll 40 is moved from the user's back to the foot according to the forward rotation drive, and the massage roll is made while the massage roll 40 moves from the user's foot to the back part according to the reverse rotation drive. It is done.
