SITTING-MAT FOR PERFORMING A SITTING POSTURE CORRECTION AND CHAIR INCLUDING THE SAME

摘要

The posture correcting cushion is symmetrically disposed on the cushion mat and the cushion mat. The posture correcting cushion has a shape extending in the left-right direction of the cushion mat. The pressure sensing units respectively output pressure sensing signals when the user is seated, And a processing unit for generating seating position information of the user based on the pressure sensing signal received from the units. At this time, each of the pressure sensing units includes a pressure sensor and a circuit board. The pressure sensor includes a body portion formed of a non-conductive material including grooves formed in a row, first protrusions located in the odd-numbered grooves and first protrusions formed of a conductive material so as to have the first height, And second protrusions formed of a conductive material to have a second height different from the first protrusion. The circuit board includes switch parts formed in a line against each of the first and second protrusions and a voltage providing line for providing a reference voltage, a first wiring for transmitting a first sensing signal, and a second wiring for transmitting a second sensing signal, And wiring portions connected to the switch portions with wirings.
