Abstract
A torso attitude sensor for attachment to a human A torso at the waist. It senses when a human torso bends past a predetermined lumbosacral angle and sounds an alarm. The sensor may be worn on the left or right side of the waist because it includes two attitude responsive switches which are inclined in directions opposite to each other. The device further includes a counter for determining the number of times the electrical circuit is connected thereby providing the person, or his or her manager, with an indication of the number of times improper bending occurs. A timer is included with which actuation of an attitude responsive switch must persist for a minimum time interval before an alarm signal or excessive bending signal is generated.
