[ The safety mat 70 includes a perimeter entry detection sensor 72, an intermittent detection sensor 74, a scale 76, and a signal transfer portion 78.

The control unit 2 typically controls the overall operation of the massage device 1. [ For example, the control unit 2 drives the air supply / discharge unit 4a, the motor 4b, and the pneumatic cylinder 4c of the massage unit driving unit 4 to operate the back massage unit, foot and leg massage unit, Units, etc., to perform massaging programs such as a vitality massage course, a stretching massage course, and a sleeping massage course. Further, the control unit 2 wirelessly transmits the wireless power to the safety mat 70 through the mat interface unit 12 in a magnetic induction manner, and wirelessly receives the detection signal.

The operation unit 3 is a wired remote control device, a wireless remote control device, a touch pad, a key, and the like, for converting an operation command of the massage device 1 into an electrical command signal and transmitting the same to the control unit 2, Buttons, and the like.

The massage unit driving unit 4 includes an air supply unit driving unit 4a, a motor driving unit 4b and a pneumatic cylinder driving unit 4c for driving a plurality of air bags and a mechanical sampler. The massage unit driving section 4 actuates the pneumatic cylinder driving section 4c to extend the piston 39 of the pneumatic cylinder 38 to move the footrest section 30 from the vertical position to the horizontal position . Then, the air bags of the leg supporting portion 32 are inflated through the air supply and exhaust device driving portion 4a to fix the ankle or the calf portion to the leg supporting portion 32. The leg support unit 32 is then moved in the forward and backward directions by driving the reciprocating feed motor 37 of the footrest unit 30 through the motor driving unit 4b of the footrest unit 30 to perform the leg stretching massage operation .

The interface unit (5) serves as a channel with all the external devices connected to the massage device (1). The interface unit 5 receives data from an external device or allows data in the massage device 1 to be transmitted to an external device. For example, it may include wired data I / O ports such as USB, short-range wireless communications such as Bluetooth, Wi-Fi, wireless LAN, and wireless cellular communications such as G3 or LTE.

The storage unit 6 stores massage program data. The storage unit 6 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory) (Random Access Memory), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM) A magnetic disk, and / or an optical disk. The control unit 2 may operate in association with a web storage that performs a storage function of the storage unit 6 on the Internet connected through the external interface unit 5. [

The seat occupancy detection unit 7 is for detecting whether or not a seat occupant is seated in the seat unit 20, and may be constituted by a pressure sensor or a proximity sensor. The control unit 2 can control the standby mode or the operation mode of the safety mat 70 in response to the detection signal of the seating detection unit 7. [

The warning unit 8 is constituted by a buzzer or a speaker and generates a warning sound under the control of the control unit 2 upon detecting an object in the surveillance area of the safety mat 70. [

The safety mat 70 includes a perimeter entry detection sensor 72 and a pinch detection sensor 74. The safety mat 70 can be controlled on / off in conjunction with the seat seating operation of the subject person. That is, before the subject is seated on the seat portion, the operation power is supplied after the seat portion of the person to be seated is kept in the operation-off state, and the approaching or sensing state of the object in the surveillance region is sensed.

7 is a flowchart for explaining an accident prevention control program according to the present invention.

Referring to FIG. 1, the control unit 2 performs a system standby mode at power-on (S100). In the system standby mode, the control unit 2 periodically transmits wireless power through the mat interface unit 12 to supply power to the safety mat 70. [ The safety mat 70 charges the battery with the supplied power and keeps the scale 76 active. The control unit 2 detects whether the subject enters the safety mat 70 through the weight scale 76 of the safety mat 70 and whether or not the weight is measured (S102). If no body weight is measured in step S102, step S100 is maintained.

When the body weight measurement of the subject is detected, the control unit 2 reads the body weight measurement data of the measured subject (S104). The control unit 2 detects whether the seat 20 of the person to be occupied is seated through the seating detection unit 7 (S106). If the seating of the subject is not detected in step S106, the control unit 2 operates only with the scale on the safety mat 70 and returns to the system standby mode in step S100.

The control unit 2 activates the safety mat 70 in the sensing operation mode and activates the peripheral entrance detection sensor 72 and the intermittent detection sensor 74 to monitor Operation is started (S108). The control unit 2 performs a programmed massage course while monitoring through the perimeter entry detection sensor 72 and the intermittent detection sensor 74. [ In step S108, when the approach of the object is detected by the safety mat 70 or the state of the object is detected (S110), the control unit 2 suspends the massage operation in progress and outputs a warning sound through the warning unit 8 (S112). The controller 2 stores the massage data at the moment of stopping the ongoing massage program in the temporary storage space for returning to the storage unit 6. [ If it is determined in step S110 that no object entry or entry is detected, step S108 is continued.

The control unit 2 keeps the temporary stop state until the object in the peripheral region of the placement area 70c or the surveillance region 74a is not detected and continuously generates the alarm sound intermittently. When the object approaching state is released by the subject or the third party, the detection signal of the safety mat 70 disappears, so that the control unit 2 determines whether or not the normal state is returned (S114). In step S114, if the object detection signal is not detected through the safety mat 70 for a predetermined time, the control unit 2 determines that the object has returned to normal state. If it is determined in step S114 that the normal return is made, the controller 2 fetches the massage data of the stopping moment from the temporary storage space and proceeds the massaging operation from the moment of the pause (S116).

The control unit 2 detects whether or not the seat portion 20 of the person to be examined is separated through the seating detection unit 7 during or after the massage progresses (S118). If the departure of the seat 20 of the subject is detected in step S118, the control unit 2 terminates the system.

FIG. 8 is a perspective view showing the entire configuration of a power supply independent safety mat according to another preferred embodiment of the present invention, and FIG. 9 is a block diagram of the power supply independent safety mat of FIG.

Referring to the drawings, a safety mat 100 of a chair type massage apparatus according to another embodiment includes a power supply unit 110, a control unit 120, an alarm unit 130, a circumferential entrance detection sensor A body weight meter 160, a body weight sensor 170,

The safety mat 100 according to another embodiment has the same configuration except that it further includes an independent power supply unit 110, a control unit 120, an alarm unit 130 and a placement detection sensor 180 in comparison with the above- do. The safety mat of another embodiment can easily add an accident prevention function to a chair type massage device having no existing accident prevention function.

The placement detection sensor 180 includes a pair of pressure detection sensors arranged in a diagonal direction within the placement area 100c of the safety mat 100. [ The controller 120 determines that the chair-type massage apparatus 1 is placed in the placement area 100c of the safety mat 100 when both of the pressure detection sensors are operated.

10 is a flowchart for explaining the operation of the stand-alone type safety mat of the chair-type mother-and-daughter apparatus according to the present invention.

Referring to FIG. 2, the controller 120 maintains the system in a standby mode when the power source 110 is powered on through a power cord (S200). In the system standby mode, the control unit 120 detects whether the chair-type massage apparatus 1 is placed in the placement area 100c of the safety mat 100 through the placement detection sensor 180 (S202). In step S202, when the chair-type massage device 1 is detected, the control unit 120 detects an entry or an entry state of an object through the circumferential entrance detection sensor 140 and the insertion detection sensor 150 (S204). In step S202 and step S204, it is determined whether or not the body weight is measured through the body scale 160 in the absence of detection of an object or detection of an object (S206). In step S206, the control unit 120 displays the body weight measurement data of the subject on the weight display unit 170 through the weight scale 160 (S208). If no weight is detected in step S206, the process returns to step S202 to perform a sensor detection loop.

In step S204, when the object access is detected in the surveillance area of the safety mat 100 or the state of the object is detected through the perimeter entry detection sensor 140 and the intermittent detection sensor 150, A warning sound is generated through the unit 130 (S210). The control unit 120 checks whether or not the object is separated (S212), and maintains the steps S210 and S212 until the object is released. If the object departure is detected in step S212, the control unit 120 ends the alarm generation of the alarm unit 130 (S214). It is checked whether or not the system has been terminated after step S214 and step S208 (step S216). If not, step S204 is performed. If the system is shut down in step S216, the power supply is interrupted and the system is shut down.
