The safety sensor 70 includes left and right safety sensors 72 and 74. The safety sensor 70 can be on / off controlled in conjunction with the seat seating operation of the subject. 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.

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

Referring to the drawing, the control unit 2 detects whether the seat 20 of the person to be occupied is seated through the seating detection unit 7 (S100). If the seating of the subject is not detected in step S100, the control unit 2 keeps the safety sensor 70 in the standby mode (S102) and returns to step S100.

The control unit 2 supplies power to the safety sensor 70 to drive the safety sensor in the operation mode so that the left and right outer side portions of the footrest unit 30 can approach the left and right sides of the footrest unit 30, And starts monitoring whether or not the object is stuck (S104). The control unit 2 checks whether the safety sensor 70 detects an object while performing the programmed massage course (S106). In step S106, when an object approach is detected by the safety sensor 70 or a state of an object is detected, the controller 2 pauses the massage operation in progress and generates a warning sound through the warning unit 8 S108). 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. [

The control unit 2 keeps the pause state until the object in the surveillance region 72a or 74a is not detected and continuously generates the alarm sound intermittently. When the object approaching state is released by the subject or the third person, the detection signal of the safety sensor 70 disappears, so that the control unit 2 determines whether the object is normally returned or not (S110). In step S110, if the object detection signal is not detected through the safety sensor 70 for a predetermined period of time, the control unit 2 determines that the object has returned to normal. If it is determined in step S110 that the normal return is made, the controller 2 fetches the massage data of the stop moment from the temporary storage session, and proceeds the massaging operation from the moment of the pause (S112).

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 (S114). If the departure of the seat 20 of the subject is detected in step S114, the control unit 2 stops power supply to the safety sensor 70 and enters the standby mode (S116).
