Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing a sleepy driving which is used for a driving seat of a vehicle such as an automobile for preventing the sleepy driving.

[0002]

2. Description of the Related Art Various devices have been proposed to prevent the driver of a car or the like from sleeping. These devices usually include sensing means for sensing that the driver is making a nap, and wake-up means for receiving the sneezing detection signal from the sensing means to wake the driver. For example, as the sensing means, if the driver starts to sleep, the driver will tilt the head forward, so the number of times the head is tilted per unit time, the time during which the head is tilted, etc. There is something that senses and sends this to the wake-up means as a wake-up detection signal, and the wake-up means operates when the above-mentioned wake-up detection signal is sent,
Some wake up with a loud noise at the driver's ear. Therefore, according to this device, when the driver makes a sneeze, it senses that the driver is making a sneeze due to the inclination of the head, thereby activating the wake-up means to wake the driver. it can.

[0003]

However, since the above-mentioned device wakes up after the driver has sowed, when the driver is sowed to the extent that it cannot be sensed by the sensing means, Sleepiness can cause loss of concentration and an accident. Therefore, in order to prevent the driver from losing concentration during traveling, if the driver feels fatigue that causes a loss of concentration, the driver can reduce the fatigue. Has been proposed. As shown in FIG. 10, a lumbar support 33 built in a backrest 32 of a vehicle seat 31 is used to massage the driver's waist, thereby reducing waist fatigue. . That is, the inverted U which is a skeleton of the backrest 32
The dial 3 is attached to both vertical members 34a of the
A pivot block 35 with a 5a is rotatably mounted, and the pivot block 35 is divided into three divided pressing blocks 3.
6a, 36b, 36c (these three pressing blocks 36
a, 36b, 36c, the central pressing block 36b
Is also used as a pressing shape changing block).
a DC motor 37 is mounted on the lower end of the DC motor 37a, and a rotating shaft (not shown) of the DC motor 37 is connected to gears 38a and 38b;
The crankshaft 40 is connected to the crankshaft 40 via a toothed belt 39, and the crankshaft 40 is connected to a pivot shaft 35 via a connecting rod (not shown).
It is connected to. If the driver feels fatigue in the lower back while driving, a changeover switch (not shown) is operated to rotate the DC motor 37 and to use the rotation of the gear 38.
a, 38b, toothed belt 39, crankshaft 40
And transmitting to the pivot shaft 35 via the connecting rod, the three pressing blocks 36a, 36b, 3
6c is rocked. Thereby, each pressing block 36
The lower part of a, 36b, 36c is pressed against the waist to rub and loosen, thereby performing massage. When the shape of the backrest surface of the backrest 32 is to be changed according to the driver's body shape, the dial 35a is manually operated to rotate the pivot shaft 35.
By the operation a, only the center pressing block 36b swings,
The backrest surface has a desired shape.

However, as described above, in the case where the three pressing blocks 36a, 36b, and 36c are rocked, and only the waist is pressed at the lower part to perform the massage, it is not possible to reduce the fatigue of the waist by the massage. Although it is possible, since only the lower back is pressed, it is not possible to apply a direct strong stimulus (such as vibration) to the driver's head. Therefore, it cannot be used as a device for preventing sleepless driving.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a sleep driving prevention device capable of effectively preventing the sleep driving.

[0006]

In order to achieve the above-mentioned object, the toying driving prevention device of the present invention has a vibration means attached to a backrest of a vehicle seat, and the backrest is prevented from being drowsy by the vibration means. It is configured to vibrate to a state.

[0007] That is, in the apparatus for preventing toying driving according to the present invention, the vibration means is attached to the backrest of the seat of the vehicle. Therefore, when the driver feels a little drowsy, the vibration means is activated to vibrate the vibration means, whereby vibration can be caused in the backrest to which the vibration means is attached.
Then, this vibration is transmitted to the back of the driver, and the driver becomes drowsy and does not sneeze. In addition, the vibration transmitted to the driver's back is also transmitted to the head, and this head can be given a strong stimulus such as vibration.
It is possible to effectively prevent sleepless driving. Especially,
With the headrest attached to the upper end of the backrest, the vibration of the backrest is also transmitted to the headrest, and a strong stimulus such as vibration can be applied to the head from the headrest. As described above, according to the present invention, a strong stimulus can be applied not only to the driver's back but also to the head, and it is possible to effectively prevent sneaking. In addition, when sleepiness is awake during the vibration generated by the device of the present invention, it is possible to receive the patient's back only by moving the back away from the backrest portion without manually stopping the vibration means during driving. Vibration can be reduced, which is convenient. Furthermore, the driver's back is vibrated by the vibration means (mainly,
The upper body of the driver is swung back and forth), which makes it possible to effectively prevent the sneezing operation with a small vibration, as compared to a device that supports the entire weight of the driver and vibrates it up and down. It is possible to reduce the size and cost of the means. In the present invention, “vibrating to a state that prevents drowsiness” means that the frequency is 5 to 50 times / minute (1 time means a reciprocating back and forth swing in the case of forward and backward vibration)
Preferably at a frequency of 8 to 42 times / min, a vibration width of 2 to 25 mm,
Preferably, it refers to applying a vibration of 3 to 15 mm. Further, in the present invention, the vehicle seat includes a driving seat of various automobiles and a seat of an operation room such as a crane truck.

Further, in the present invention, when the vibration means is incorporated in the backrest portion, the dead space in the backrest portion can be effectively used to prevent the backrest portion from being enlarged. Further, in the present invention, when the vibration means is disposed outside the backrest,
When replacing the components of the vibration means, there is no need to disassemble the backrest, and the work can be performed quickly. In addition, the shape and the like of the vibration means can be set irrespective of the shape and the like of the backrest. Further, noise such as chattering noise generated by the vibration of the vibration means is easily heard by the driver, and can be effectively used as the awakening sound.
