AI Technical Summary
The inclination of vehicle seats to the left due to road drainage design causes driver discomfort and health issues such as low back pain, neck pain, and shoulder stiffness.
A seat tilting plate is designed with the left side higher than the right side to maintain the driver's seat horizontal, correcting the body axis alignment.
Corrects the driver's body axis alignment, alleviating discomfort and preventing accidents by improving posture, thereby enhancing driving comfort and safety.

Abstract
Description
Technical Field
[0001] This invention relates to a seat plate for automobiles that is inclined several times to the right to correct the situation where the road is inclined several times to the left.
Background Art
[0002] On paved roads where vehicles run, for rainwater drainage, there is an inclination of several degrees (generally about 3 degrees) towards the left. Naturally, the seat of the vehicle is inclined to the left, and for this reason, the driver's body axis was always inclined to the left.

Summary of the Invention
Problems to be Solved by the Invention
[0003] Due to the driver's body axis always being inclined to the left, the body axis is instinctively bent to the right. As a result, without realizing it, the waist, neck, and back muscles are burdened, causing problems such as low back pain, back muscle pain, neck pain, and shoulder stiffness. This invention attempts to solve the problem by correcting the left inclination of the seat, which is the root cause.
Means for Solving the Problems
[0004] This invention keeps the driver's seat horizontal by laying a seat inclination plate with the left side several degrees higher than the right side on the seat, and solves the problems of low back pain, back muscle pain, neck pain, and shoulder stiffness of the driver caused by the left inclination of the driving seat.
Effects of the Invention
[0005] As described above, by using the automobile seat inclination plate inclined several degrees to the right of this invention, it corrects the inclination of the driver's body axis to the left, improves problems such as low back pain, back muscle pain, neck pain, and shoulder stiffness, promotes comfortable driving, and ultimately leads to accident prevention.
Brief Description of the Drawings
[0006] [Figure 1] This is a cross-section of a typical paved road that slopes towards the drainage ditch (to the left). [Figure 2] This is a cross-sectional view of the vehicle chassis and driver's seat on a paved road. [Figure 3] This is an external view of a distorted torso where the person's lower back is perpendicular to the sloping road and seat surface, and the upper body is aligned with the Earth's vertical axis. [Figure 4] This is a cross-sectional view of the vehicle chassis and driver's seat on a paved road, with a seat tilt plate installed on the driver's seat surface, raising the left side by a few degrees, to correct the seat surface to a horizontal position. [Figure 5] This is a front view of a seat tilt plate that corrects the leftward tilt of the driver's seat cushion. [Modes for carrying out the invention]
[0007] The seat tilting plate is higher on the left side and gradually becomes thinner towards the right. By installing this seat tilting plate on the driver's seat, the driver's body, which was tilted to the left due to the downward slope of the road surface to the left, is lifted to the right, correcting the torso perpendicular to the axis of gravity, and improving lower back pain, back muscle pain, neck pain, and stiff shoulders. [Examples]
[0008] An embodiment will be described below with reference to the attached drawings. Figure 1 is a cross-section of a typical paved road. The road slopes downward to the left towards the gutter to facilitate rainwater drainage from the centerline. Figure 2 is a cross-section of the interior of a car traveling on the left side of the road, showing the chassis and the area around the driver's seat. Both the chassis and the driver's seat surface are sloped downward to the left from the horizontal line, following the slope of the road. Figure 3 is a diagram showing the torso of a driver on the driver's seat surface. Due to the leftward slope of the driver's seat surface, the lower back of the torso is tilted to the left, while the upper part is vertical. Figure 4 is a diagram showing the driver's seat surface leveled by installing a seat tilt plate that is thicker on the left side and thinner on the right side. Figure 5 is a front view of a seat inclined plate, which is thicker on the left and thinner on the right. Explanation of symbols
[0009] 1. The horizontal line of a road. 2. A paved road surface on which vehicles pass. 3. Vertical axis relative to the paved road surface 4. Vertical axis relative to the horizontal line of the road 5. Driver's seat tilted to the left. 6. An inclined board installed on the driver's seat surface, with the left side higher and the right side lower. 7. The left-side downward-sloping driver's seat cushion that is originally installed in the car. 8. The horizontal line of the driver's seat surface corrected horizontally with a seat tilting plate.
Claims
[Claim 1] An inclined seat plate for automobiles, characterized by its ability to tilt the driver's seat a few degrees to the right, thereby absorbing the leftward slope of the road, correcting the driver's posture, and improving conditions such as lower back pain, back muscle pain, neck pain, and stiff shoulders.
