Description

The present invention relates to a vehicle seat that is suitable for preventing the driver from accidentally depressing the accelerator pedal.

Conventionally, there is known a technology for equipping a vehicle with an erroneous depression response device to prevent the vehicle from suddenly starting due to an erroneous operation in which the driver erroneously depresses the accelerator pedal. For example, the erroneous depression response device described in Patent Document 1 has an erroneous depression detection means for detecting an erroneous depression, and a driving force limiting means for implementing a driving force limiting control, which is a control for limiting the driving force, when an erroneous depression is detected.

JP 2019-206206 A

The present invention aims to provide a vehicle seat that makes it easier to depress the brake pedal and prevents accidental depression of the accelerator pedal without equipping the vehicle with an erroneous depression prevention device.

The invention of claim 1 is a vehicle seat in which an accelerator pedal is located on the right side of a driver's seat cushion and a brake pedal is located to the left of the accelerator pedal, and a bank portion is placed on the right side and front side of the seat cushion, which is set next to the driver's thighs and against which the thighs come into contact , and the bank portion is made of an add-on cover pad .
The invention according to claim 2 is the vehicle seat according to claim 1, wherein a bank portion is also provided on the left side of the seat cushion.
The invention of claim 3 is a vehicle seat as described in claim 1 or 2, wherein the vehicle-outside shape of the front end of the bank portion provided on the right side of the seat cushion is cut so as to form a downward slope from the top of the bank portion toward the outside of the vehicle.

Elderly drivers, in particular, tend to have their thighs spread outward. This means that the right leg that presses the accelerator pedal is likely to turn to the right side of the seat cushion, making it difficult to naturally press the left brake pedal. Or, when suddenly applying the brakes, the accelerator pedal may be pressed.

In the present invention, a bank is provided on the right front side of the seat cushion, which applies a reaction force to the right foot of the driver toward the left side, making it easier to step on the left brake pedal with the right foot and preventing erroneous stepping on the accelerator pedal.

In addition, in the present invention, the bank portion is provided on the right and front side of the seat cushion, and is not provided over the entire area along the front-to-rear direction of the right side of the seat cushion facing the outside of the vehicle, so it does not interfere with the driver getting in and out of the vehicle.

In addition, in normal seats, excluding competition bucket seats, the left and right edges of the seat cushion are relatively flat, and the right edge applies a reaction force to the driver's right foot toward the left, so it is not possible to expect the driver's right foot to move to the left.

In addition, competition bucket seats have hard mounds on the entire front-to-rear area of the right and left sides of the seat cushion to support the driver, making it difficult to get in and out of the seat and making it difficult to use in normal situations.

FIG. 1 is a perspective view showing a seat cushion of a vehicle seat according to an embodiment of the present invention. FIG. 2 is a side view showing the seat cushion of FIG. 3A and 3B are schematic cross-sectional views of the seat cushion of FIG. 1 and FIG. 2, where FIG. 3A is a cross-sectional view taken along line A-A of FIG. 2, and FIG. 3B is a cross-sectional view taken along line B-B of FIG. FIG. 4 is a side view showing a seat cushion according to a modified example of the vehicle seat. 5A and 5B are schematic cross-sectional views of the seat cushion of FIG. 4, where (A) is a cross-sectional view taken along line A-A of FIG. 4, and (B) is a cross-sectional view taken along line B-B of FIG.

The vehicle to which the vehicle seat 10 of the present invention is applied has an accelerator pedal located to the right of the driver's seat cushion 11, and a brake pedal located to the left of the accelerator pedal.

In this specification, the right side will be referred to as the "right side", the left side as the "left side", and the front side as the "front side" when facing the front of the vehicle.

As shown in Figures 1 to 3, the vehicle seat 10 has a bank portion 12 on the right and front side of the seat cushion 11 that is raised higher than other parts of the seat cushion 11.

In other words, the vehicle seat 10 supports braking operations by the right foot 1R when the driver sits on the seat cushion 11, with the thigh of the right foot 1R coming into contact with the bank portion 12, which applies a reaction force to the thigh of the right foot 1R to the left, and pulls the entire right foot 1R to the left.

At this time, in order to allow the driver to get in and out of the vehicle seat 10 with ease, the bank portion 12 is not set next to the driver's waist, but is set partially next to the thighs (groin to knees).

In FIG. 3, C indicates the center of the seat, 1R indicates the right leg, and 1L indicates the left leg. F indicates the reaction force that the bank portion 12 exerts on the thigh of the right leg 1R, which is indicated by a solid line.

As a specific embodiment of providing the bank portion 12 on the seat cushion 11 of the vehicle seat 10, a member with appropriate hardness and cushioning properties, such as a urethane pad, is placed on the right side and front side of the seat cushion 11, and a shape is set in which only the right side and front side is raised higher than the other parts of the seat cushion 11.

The shape of the seat cushion 11 with the bank portion 12 may be formed by the cushion pad itself, or the bank portion 12 made of a cover pad may be placed on the cushion pad. A cover pad with a bank portion 12 may be attached to an existing normal seat.

As shown in Figures 4 and 5, the vehicle seat 10 can be cut (cut line K) at the front end of the bank portion 12 provided on the seat cushion 11 in the front-rear direction of the vehicle while maintaining the vehicle inside shape of the front end shown in Figure 5 (B). This makes it less likely that the driver's right foot 1R will hit the bank portion 12 when getting in and out, improving the ease of getting in and out.

For the vehicle seat 10, in consideration of the design or to prevent the left foot 1L from leaning toward the center console of the vehicle, a raised shape may be added not only to the right side (outside of the vehicle) of the seat cushion 11 but also to the left side (inside of the vehicle) (symmetry is not an issue).

According to this embodiment, the following advantageous effects are obtained.
In the present invention, a bank portion 12 that is raised higher than other portions of the seat cushion 11 is provided on the right side and front side of the seat cushion 11. As a result, the bank portion 12 applies a reaction force to the left side to the driver's right foot 1R, making it easier to step on the left brake pedal with the right foot, and preventing erroneous stepping on the accelerator pedal.

In addition, in the present invention, the bank portion 12 is provided on the right and front side of the seat cushion 11, and is not provided over the entire area along the front-rear direction of the right side of the seat cushion 11 facing the outside of the vehicle, so it does not interfere with the driver getting in and out of the vehicle.

Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration of the present invention is not limited to this embodiment, and the present invention also includes design changes that do not deviate from the gist of the present invention.

The present invention provides a vehicle seat that makes it easier to depress the brake pedal and prevents accidental depression of the accelerator pedal without equipping the vehicle with an erroneous depression prevention device.
