The present invention relates to a waist support plate adjustment device of the car seat, in particular, to install the back support board inside the back seat of the car seat, by adjusting the angle of the board using the tension of the wire, according to the body shape of the driver It relates to a waist support plate adjustment device of the car seat that allows the waist to be born.

In general, the front seat of the vehicle is provided with a waist support to increase the seating feeling of the driver.

However, the waist support is defined in a certain form according to the model form of each vehicle at the time of shipment of the vehicle, and the prescribed waist support is fixed or only a minute change is made.

Therefore, when a long time passes after the vehicle leaves the vehicle, the lumbar support is loosened in its original tension by the force of the driver pushing toward the back. Therefore, the lumbar support loses its pretext, and there is a risk that fatigue may accumulate during long time driving and act as one of driving obstacles.

The present invention has been made in view of the above problems, and its purpose is to adjust the backrest plate freely, so that even if a long time has passed after the vehicle is released, the backrest plate adjustment of the car seat can be operated in a comfortable choker state. To provide a device.

In order to achieve the above object, according to the waist support plate adjustment device of the automobile seat of the present invention, the head rest, the cushion chain seat back pad and the waist support is built in, the exterior is made of leather or textile seat back cover body In the seat structure of the seat, the seat back frame is installed in the seat around the driver's waist, the seat back frame is installed to be movable on the rotation axis and fixed to both sides of the seat, and each of the seat back frame at least 1 The rollers, one end is fixed to any one of the seat back frame, the other end is a wire wound around the winding body, characterized in that the winding body is connected to a predetermined winding device.

Therefore, when the waist supporter or the support plate is relaxed, the driver winds the winding body using the winding device so as to adjust it to his / her body shape, and the wire is wound around the winding body. Since the wire is fixed to the seat back frame, the tension is increased to pull the support plate toward the driver. As a result, the loose state of the support plate is eliminated, and even if a long time has passed since the vehicle leaving the vehicle, there is an effect that it can always be operated in a comfortable feeling of chuckling.

EXAMPLE

1 is a partially cut perspective view showing an embodiment of the present invention, and FIG. 2 is a side view thereof. In the figure, reference numeral 10 denotes the front seat of the vehicle. The seat 10 has a seat back pad which is a cushioning body not shown in the interior thereof, and its exterior is covered with a seat back cover body 12 made of leather or textile material. Reference numeral 14 is a head rest. See FIG. 3.

The seat 10 is provided with a waist support 20 (hereinafter referred to as a 'support') near the driver's waist. The pedestal 20 forms a flat plate shape and is slightly bent to correspond to the waist shape of the human body. The pedestal 20 is provided with a frame for fixing the entire sheet 10 and an immediate tumble frame 24 at both sides of the sheet 10. The lower part of the seat back frame 24 is installed to be movable on the rotating shaft 26 so that the entire backrest can be folded back or folded forward by the driver's operation.

In addition, at least one roller 28, 28 is rotatably provided in each of the seat back frames 24, 24, and the wires W span the rollers 28, 28, respectively. . One end of the wire W is fixed to one of the seat back frames 24, and the other end is wound around the winding body 30. As shown in FIG.

The winding body 30 is connected to a predetermined winding device. As shown in FIG. 3, this winding device can use the worm 32 and the worm gear 34, or can use an automatic winding device by electric drive.

In addition, the handle 36 may be additionally provided at the end of the worm 32 or may be configured in a lever type so as to conveniently operate the worm 32 and the worm gear 34. Reference numeral 40 is a variable bracket for supporting the seat back frame 24 and the rotating shaft 26 and adjusting the angle of the seat.

Next, the effect of the present invention will be described.

The seat 10 of the shipped car is leaned back by the driver pushing toward the back as a long time elapses, and the back support inside the seat 10 is also pushed backward, thereby supporting the waist. Will not exert.

However, in the present invention, a flat pedestal 20 is installed inside the seat 10, and the pedestal 20 is moved to the front side, that is, the driver's side by using a wire W or the like. As a supporting support, it was able to perform a sufficient function. Figure 4 (a), (b) is a schematic cross-sectional view for explaining the operating state of the present invention. Referring to this figure again, when the pedestal 20 of the present invention is loosened after being pushed out to the rear of the driver, the user easily feels fatigue when driving.

At this time, in order to adjust the pedestal 20, as shown in FIG. 3, when the handle 36 attached to the winding device is turned to one side, that is, the wire W is wound on the winding body 30. When turned in the direction, since the one end of the wire W is fixed to the seat back frame 24, the tension of the wire W is increased while being guided to the rollers 28 and 28.

Then, as shown in FIG. 4 (a), in the state where the pedestal 20 is pushed back from the seatback frame 24, as shown in FIG. 4 (b), to the front side of the seatback frame 24. Will go out. If it is continuously adjusted to the driver's body shape, the adjustment state is maintained according to the characteristics of the conventional worm and worm gear, and no stopper mechanism is necessary.

As described above, according to the waist support plate adjusting device of the automobile seat of the present invention, by installing a board (support plate) supporting the waist inside the backrest of the car seat, by adjusting the angle of the board using the tension of the wire It is a useful design to support the waist according to the driver's body type.
