The invention specified in protection claim 1 is based on the problem of creating an early warning system that every driver who wears these anti-sleep goggles warns him and him of falling asleep at the wheel signals to take a break from driving.

This problem is solved according to the invention with an anti-sleep goggles best for drivers Combined from a spectacle frame with an integrated optoelectronic eyelid detection unit with an electronic evaluation unit.

With the invention it is achieved that with the anti-sleep goggles the lid closure duration of the eyelids over is monitored or evaluated, d. H. if the eyelids are stored in the electronic evaluation unit exceed the normal value of an eyelid closure duration, which signals that the driver is falling asleep and that Controlling a motor vehicle at risk, an alarm signal is triggered optically and acoustically and at Connection to a satellite navigation system automatically replaces the onward journey.

Further advantageous embodiments of the invention are the subject of claims 2 to 8.

These advantageous developments enable the anti-sleep goggles to function, in terms of structure, shape and Configuration to be configured so that an exact determination of a too long closing of the eyes guaranteed an alarm. The anti-sleep goggles can be used with or without glass frames rection of a possible ametropia and has a central nose bridge, which is in height in is individually adjustable, as well as extended arch jaws, one of which is adjustable via a slide has the recording of the optoelectronic eyelid detection unit, so that through the heights vertical adjustment of the nose bridge combined with the horizontal adjustment of the slide an individual setting of the light beam on the cornea / dermis as well as that of an IR / miniature video camera is guaranteed. The anti-sleep goggles can be used directly with a cable or by radio with the elek tronic evaluation unit or a satellite navigation system that triggers an alarm or the onward journey also takes over automatically, be connected. The electronic evaluation unit can also in the eyeglass frame, temple and middle part, can be accommodated in miniature, in this case the Stromver battery integrated in the socket and the electronic evaluation unit perform the function of a Charging station takes over.

In Figs. 1/2/3 and 4, embodiments of the invention are shown. Show it:

Fig. 1 the anti-sleep goggles ( 1 ) in the front view with a central, vertically adjustable nose bridge ( 3 ) which is locked with the screw ( 1 b) in the guide ( 2 ). The side parts ( 1 d) of the glasses are designed so that they go down as far as possible to achieve an individual height adjustment with the nose bridge ( 3 ), via a short vertical path so that the optoelectronic unit ( 4 ) is at eye level. With ( 5 ) glass edges are shown that serve to accommodate correction glasses in the case of an ametropia. ( 1 c) may be indicator lights for alarm and function.

Fig. 2 shows the right side of the temple from the inside with ( 1 a) the extended arch jaw, the slide ( 4 c) for receiving the optoelectronic unit ( 4 ) with its light source ( 4 a), the photo element ( 4 b), which is also a Miniature IR or video camera can be connected with the cable ( 8 ) to the electronic evaluation unit ( 9 ). The eyeglass temple ( 6 ) has in its anatomically adjustable temple integrated batteries ( 6 a) at the end of which the cable connection ( 8 ) is omitted when they are used and the external electronic evaluation unit ( 9 ) is then replaced by a charging station. ( 6 b) is a hinge that connects the middle part with the bracket. ( 7 ) is an alarm device (loudspeaker) integrated in the temple.

Fig. 3 shows the electronic evaluation unit ( 9 ) with alarm transmitter ( 10 ) and indicator light ( 11 ) and ( 12 ) the electronic connector with poles suitable for the cigarette lighter in a car.

Fig. 4 shows the arrangement of the optoelectronic unit ( 4 ), in its place also a miniature IR or video camera is used, with the light beam emitted by its light source ( 4 a) and reflected on the eye to the photo element ( 4 b) ( 4 d), on the adjustable carriage ( 4 c).

In Fig. 1 an anti-sleep goggle ( 1 ) is shown which has the shape of a simple beam glasses. The nose bridge ( 3 ) is individually varied vertically in height by the guide ( 2 ) with the screw ( 1 b) so that the optoelectronic component / miniature IR or video camera ( 4 ) is adjusted to the eye level of the spectacle wearer. The optoelectronic component ( 4 ) is predominantly in the extended right arch jaw on a horizontally adjustable slide ( 4 c) attached Fig. 2 + 4 which is adjusted so that the emitted from the light source ( 4 a) of the optoelectronic unit ( 4 ) Light beam ( 4 d) is reflected on the eye and is precisely received by the photo element ( 4 b) or, when using a miniature IR / video camera ( 4 ) to detect an eyelid, enables individual adjustment. In order to function as anti-sleep goggles, a small, slightly irritating light beam (colored or infrared) ( 4 d) is emitted from the light source ( 4 a) onto the cornea / dermis of the eye and to the photo element ( 4 b) (photo cell / photo resistor / Phototransistor / Photodetector / Photodiode), which forwards this information via the cable connection ( 8 ) or by radio to the electronic evaluation unit ( 9 ) Fig. 3. If a lid closure now interrupts the light beam reflection on the eye for so long that a standard value defined in the electronic evaluation unit ( 9 ) is exceeded, with an eyelid closure time that does not yet pose a risk for driving a car, or is detected as such by the miniature IR / video camera so the optical as well as acoustic trigger an alarm transmitter (7/10/11), the desired alarm is adapted from the so he does not frighten the driver. The glass frames ( 5 ) serve to accommodate correction glasses or sun protection glasses. Fig. 3 shows in this embodiment the electronic evaluation unit ( 9 ) as an external device which has the electronic plug ( 12 ) with its contacts for the power supply suitable for the usual cigarette lighter socket of a car and via the cable connection ( 8 ) with the anti Sleeping glasses ( 1 ) is connected.
