ABSTRACT:
A drowsiness warning device includes a band which is securable about a wearer's neck, and an alarm positioned by the band below the wearer's chin for producing a tactile and an aural warning as the chin contacts the alarm device. The band includes a central section formed with a vertically stiff plastic material which is capable of holding a lower elongated body of the alarm therein. An upper rounded dome section of the alarm extends above the central section. The band also includes a pair of straps having hook and loop tape fasteners, and intermediate sections between the straps and the central section lined with a fibrous material for wearer comfort. In one embodiment, the alarm includes a hollow elastomeric ball having a mechanical noisemaker disposed within an air inlet/outlet aperture for the ball. In another embodiment, the alarm includes an electrically actuated speaker connectable to a battery on depression of the upper rounded dome.
