Abstract

The invention relates to a system and device for alerting drivers who fall asleep while driving. The system and device would automatically be activated when they sense that the driver is in a state of falling asleep or slumbering. The sensing means (3) would be mounted on the steering wheel (1) and would be sensitive to the driver's grip of the steering wheel (1).

Description

MEANS FOR PREVENTING A DRIVER FROM FALLING ASLEEP
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates to means which would prevent a driver from falling
asleep while driving.
Many factors, such as fatigue, stress, long continuous driving, exposure to long
monotonous engine, heat and the like cause that drivers fall asleep or slumber
during driving. Furthermore the "reaction-time" of drivers in such a situation is
prolonged, thus raising the chances of their being involved in accidents,
collisions and the like.
OBJECTS OF THE INVENTION
It is thus the object of the present invention to provide a system which will sense
the driver's awareness, emit a sound which would alarm and wake the driver. It is
important that the device be automatically activated.
It is thus a further object of the present invention to present an automatic system. SUMMARY OF INVENTION
According to the invention there is provided a system and a device which would
automatically be activated when it senses that the driver is in a state of falling
asleep or is slumbering. The device would alert the driver by activating an
acoustic signal or activating the car's radio very loudly or any other similar
means.
The system comprises a sensing means mounted on the steering wheel and being sensitive to the grip of the driver's hand on the wheel when the hand grip
would be even slightly loosened the alarm would be activated. The power supply
activating the alarm could be an independent battery or it could be connected to the car's electrical system.
SHORT DESCRIPTION OF THE DRAWINGS
The invention will now be described with reference to the annexed drawings in
which:
Figure 1 is a schematic top view of a steering wheel, being part of the system.
Figure 2 is a cross section of the wheel of Figure 1.
Figure 3 shows schematically the sensing means, while
Figures 4a and 4b depict examples of the activating switch. DESCRIPTION OF PREFERRED EMBODIMENT
Turning to Figures 1 and 2 a steering wheel 1 is provided with a circumference
elastic tube 3 being branched off by section 5 at the free end of which there is
provided an adjustable low pressure air switch 7 (see Figure 3).
Air switch 7 is connected to air tube 5 in its "open" position (Figure 4b). As long
as the steering wheel is held firmly by the driver the said air switch would remain
in its "open" position. Once the hand grip of the driver is loosened, the air switch
would close and establish contact between terminals 10 and 11 which close on
electric circuit of any alarm system or any other audible means of generally
known type.
By means of adjusting screw 12 the sensitivity of the air switch could be
changed.
It is quite obvious that the alarm could also be adjusted.

Claims

1. A system for activating an alarm to prevent drivers from falling asleep or
slumber which comprises sensing means being mounted on the steering
wheel of a car and being sensitive to the grip of the driver's hand on the wheel
said sensing means being connected to a switch which would activate an
alarm.
2. A system as claimed in claim 1 , wherein said sensing means is an elastic tube mounted on the driving wheel.
3. A system as claimed in claim 1 for activating an alarm to prevent drivers from
falling asleep or slumber, where said switch is an air switch connected to said
elastic tube.
4. A system as claimed in claim 1 , wherein said alarm is an independent audio
means.
5. A system as claimed in claim 1 , wherein the system is connected to the car's
audible devices.
6. A system as claimed in claim 1 , wherein said air switch is adjustable.
