ABSTRACT:
An electronic posture position sensor device for alerting the user whenever an incorrect posture is assumed. The posture position sensor includes an electrical circuit that includes, a power means, a switch assembly, an electronic timer capable of being set at predetermined cycles, and an alerting means. The switch assembly comprises a first conducting pendulum and two sensor terminals attached, respectively, to second and third selectively positionable conducting pendulums. The second and third pendulums have a clamping means which allow the user to manually position the second and third pendulums for different sitting positions. When an incorrect posture is assumed, the switch assembly is opened which allows current to flow from the power means through the circuit to the timer. When the predetermined timer cycle elapses, the current causes the alert means to alert the user when sitting in an incorrect sitting position.
