A monitoring unit is mounted atop headgear fitted with a proportional level sensor which detects head inclination in the saggital plane. A battery powered microcontroller, interfaced with the level sensor, monitors the head tilt and provides a sonic indication whenever the tilt exceeds preset limits to the front or rear. The use of a proportional level sensor of the capacitive/fluid type enables the microcontroller to be configured to allow the user to preset different tilt limits, and to select different modes, for example beginning or advanced training, sitting, standing or exercising body positions, and to set up a designated training session duration, timed by sonic indication, during which the number and direction of head tilt deviations detected may be counted. Such statistical data may be displayed to the user on an LCD display. With the level sensor mounted directly to one side of the headgear, the monitor unit in a housing atop the headgear may specially non-rigidly attached to provide a degree of wobble or totter perceptible to the user as kinesthetic/proprioceptive feedback, in addition to the audible biological feedback received from the sonic tilt limit indication. The microcontroller system may be specially configured to recognize and ignore gross movements such as reaching or bending, while still feeding back to the user the finer postural deviations. |

DETAILED DESCRIPTION In the perspective top view of FIG.
1, headgear 10 for carrying a posture-monitoring device of the present invention has a sun visor brim 12 attached to a headband 14 which has a central strap 16, formed to follow the outline of the head along the wearer's saggital plane.
Strap 16 is attached to headband 14 at front and rear, and a cross strap 18 is adjustably attached to headband 14 at two opposite side locations immediately above the ear.
Strap 16 is made adjustable in length at the rear of the headband 14.
At the intersections of straps 16 and 18, a fastener 20 is provided for attaching a monitor unit (not shown).
Adjustments for head size and shape are provided by conventional adjustable fastening means such as dome or slide type fastenings: the headband 14 and straps 16 are made adjustable at the rear, and cross strap 18 is made adjustable in length and lockable on both sides.
Preferably visor peak 12 is made removable from headband 14, e.
g.
by means of snap fasteners.
FIG.
2 is a perspective view of the headgear unit 10 of FIG.
1, showing visor peak 12, headband 14, straps 16 and 18, and monitor fastener 20.
A level sensor element 22 is shown attached on one side of strap 18.
FIG.
3 is a perspective view of an embodiment of the posture monitor of the present invention wherein the headgear is styled to have a visor peak portion 12A made integral with a headband 14A.
A monitor unit 24, shown attached at the intersection of straps 16A and 18A, includes a sonic indicator, battery, controls and circuitry to work in cooperation with level sensor 22, which may be mounted within one side of strap 18A as shown, in either an exposed or concealed manner.
A lightweight underhat lining 26, seen between straps 16A and 18A, is made from breathable terrycloth-like material; as well as being absorbent of perspiration, lining 26 serves to in effect grip the user's hair and to distribute the weight of the monitor unit 24 so as to avoid any distracting pressure points and to allow the weight of the monitor unit to be fully perceived by the user
