Abstract

To provide a tilting seat for an automobile that improves the situation where the driver's lower back leans to the left and the upper part of the trunk becomes vertical, resulting in a "L-shaped" posture due to the road surface being tilted to the left, and unconsciously causing physical discomfort such as lower back pain, back pain, stiff shoulders, etc. [Solution] The inclined car seat of this invention uses an attachment 6 to lift the seat surface 7 of the driver's seat 5, which is tilted to the left along the paved road, and by correcting the seat surface to a horizontal position, the trunk is kept vertical, which helps to alleviate physical discomfort such as lower back pain, back pain, and stiff shoulders.

Description

[Technical Field]

[0001] The invention relates to a car seat that tilts a few degrees to the right to compensate for the road tilting a few degrees to the left. [Background technology]

[0002] The paved roads on which cars travel are tilted to the left by several degrees (generally about 3 degrees) to allow for rainwater drainage. Naturally, the car seat is tilted to the left, which means that the driver's body axis is always tilted to the left. [Prior art documents] (I couldn't find it on J-PlatPat or through internet searches) Summary of the Invention [Problem to be solved by the invention]

[0003] Because the driver's body axis is always tilted to the left, it unknowingly puts strain on the lower back and spine, causing lower back pain, back pain, stiff shoulders, etc. The aim is to solve this problem by correcting the root cause, which is the seat tilting to the left. [Means for solving the problem]

[0004] This device keeps the driver's seat horizontal by lifting the left edge of the driver's seat cushion with a bolt or attachment, thereby solving the problems of lower back pain, back pain, and stiff shoulders for the driver. In addition, the problem can be easily solved in existing cars by using a seat tilt plate that is a few degrees higher on the left side. [Effects of the Invention]

[0005] As mentioned above, by using the inclined car seat and car seat tilt plate of this invention, which are tilted a few degrees to the right, the axis of the driver's body can be corrected to tilt to the left, improving lower back pain, back pain, stiff shoulders, etc., promoting comfortable driving and ultimately helping to prevent accidents. On the passenger side, the body leans to the left when the road is inclined, but this is not a problem as the door naturally supports the body. [Brief explanation of the drawings]

[0006] [Figure 1] This is a cross-section of a typical paved road that slopes toward the gutter (to the left). [Figure 2] A cross-sectional view of the chassis and driver's seat on a paved road. [Figure 3] This is an external view of a person sitting on the driver's seat, with their lower back perpendicular to the inclined road and seat, and their trunk distorted as their back and above are aligned with the Earth's vertical axis. [Figure 4] This is a cross-sectional view of the chassis and driver's seat on a paved road when the left side of the driver's seat is lifted with bolts or attachments and the seat is adjusted to be horizontal. [Figure 5] This is a front view of a seat tilt plate that easily corrects the tilt of the driver's seat cushion to the left. DETAILED DESCRIPTION OF THE INVENTION

[0007] The left side of the seat support bracket should be a few degrees higher than the right side and level. A bolt or the like is provided on the left side of the seat surface, which is parallel to the chassis, and by turning this, the seat surface can be made horizontal or raised to a desired angle. Alternatively, a simpler seat tilt plate that achieves the same effect can be made higher on the left side and gradually become thinner towards the right. By installing this seat tilt plate on the driver's seat, the driver's body, which has been leaning to the left due to the road surface sloping downward to the left, can be lifted to the right, correcting the driver's trunk perpendicular to gravity and improving lower back pain, back pain, stiff shoulders, etc. [Example]

[0008] An embodiment will now be described with reference to the accompanying drawings. 1 is a cross-section of a typical paved road. To make it easier for rainwater to flow away from the center line of the road, it slopes downward on both sides toward the gutter. 2 is a cross-section of the chassis and driver's seat area showing the interior of a vehicle traveling on the left side of the road. Both the chassis and driver's seat slope downward to the left from the horizontal line in line with the slope of the road. 3 is a diagram showing the driver's trunk on the driver's seat. As the driver's seat is tilted to the left, the lower back of the trunk is tilted to the left and the upper part is vertical. 4 is a diagram in which the left edge of the driver's seat has been lifted to make it horizontal. Possible methods for lifting the left edge include bolts, notches, attachments, welding, etc. (hereinafter referred to as attachments). 5 is a front view of a seat slope plate that is thicker on the left side for existing vehicles, so that the same effect as 4 can be easily achieved.

Claims

1. This inclined seat for an automobile is characterized in that the driver's seat of the automobile is tilted to the right by several degrees to absorb the left-side inclination of the road, correct the driver's posture, and improve lower back pain, back pain, stiff shoulders, etc.

2. This car seat tilt board is installed to tilt the driver's seat of a car to the right by a few degrees, absorbing the left-side slope of the road and correcting the driver's posture, thereby alleviating lower back pain, back pain, stiff shoulders, etc.
