Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a floor spacer for a vehicle that allows even a short person to obtain a suitable driving position, and particularly to a vehicle floor spacer that can adjust the driving position in response to pedal operation. This invention relates to a vehicle floor spacer.

<Conventional technology> In addition to the retention performance of a driver's seat in an automobile, the relative positional relationship between the seated driver and driving devices such as the steering wheel and accelerator pedal, so-called proper Setting the driving position that can be controlled is also an important item.
It's becoming one. The setting of this driving position is largely influenced by factors such as the height of the driver, but the largest 5% of target drivers are
The goal was to be acceptable to 90% of users, excluding the smallest 5%, and the sliding adjustment of the seat,
Steering wheel angle adjustment mechanisms are used.

<Problems to be Solved by the Invention> By the way, FIG. 5 shows the appropriate angle A ₁ of the human body when the driver 1 operates the accelerator pedal 2.
This is an example of finding A ₂ and A ₃ . a is the heel point, b is the knee point, c is the hip point, A ₁ is the hip angle centered on the hip point, A ₂ is the knee angle centered on the knee point b,
_A3 is the ankle angle when the accelerator pedal 2 is depressed with the heel point a as the fulcrum. Here, the suitable driving angles are 95° < A ₁ < 120°, 95° < A ₂ <
The range is 135, 90° < A ₃ < 110°. Furthermore, Fig. 6 compares knee and ankle angles A ₂ and A ₃ between an average short person and a tall person. As is clear from the same comparison, in the case of a short person shown by the solid line, the knee angle A ₂ is larger and the ankle angle A ₃ is smaller than that of a tall person shown by the broken line.
This is because when a short person uses a slide device to adjust the position of the human body forward in relation to the steering wheel and pedal operation, the height from the floor 4 to the accelerator pedal 2 remains the same. This is due to the fact that the heel point a is moved by a length l toward the accelerator pedal 2 side. In this way, the heel point a moves forward and the ankle angle _A3
If this becomes small, not only will the operability of the accelerator pedal 2 become worse, but also the thigh 3 held at the tip of the seat cushion will be compressed when the pedal is depressed, making it easy for the rider to get tired. Furthermore, in the case of extremely short persons, the heel point a was sometimes separated from the floor 4.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a floor spacer for a vehicle that can adjust the driving position relative to the pedals to an appropriate position, especially when operating the pedals by short people. .

<Means for solving the problems> That is, the vehicle floor spacer of the present invention has the following features:
Floor spacer body 9 made of resin molded product such as chip urethane having a wide surface for resting the feet of the driver 1
and brackets 7 and 70 inserted into the floor spacer body 9 so as to protrude from opposite sides of the floor spacer body 9, and the brackets 7 and 70 are connected to the tunnel portion 41 or side sill 4.
The floor spacer 9 is characterized in that it has such a thickness that its wide footrest surface is at a predetermined height above the vehicle floor 4 when attached to a vehicle body fixing part such as a second vehicle body.

<Function> The driver's heel point a becomes higher by the predetermined thickness of the floor spacer main body 9. By operating the pedals using the raised heel point as a fulcrum, the ankle angle of a short person when pressing the pedal can be corrected to a value similar to that of a tall person, and an appropriate driving position can be obtained. .

<Example> FIG. 1 shows a driving position when a floor spacer according to the present invention is applied.
In the figure, a floor spacer 6 made of a holding member is provided on a vehicle body floor 4 at a position in front of a seat 5, and a driver 1 places his/her feet on the floor spacer 6 to operate pedals such as an accelerator pedal 2. It is becoming. Further, the seat 5 is attached to the attachment portions 4a and 4b of the floor 4 via a slide device 51, and can be slid as appropriate depending on the physique of the driver 1.

FIGS. 2 and 3 show the specific structure of the floor spacer. The floor spacer 6 has a wide surface for resting the feet of the driver 1, and includes a floor spacer body 9 made of a resin molded product such as chip urethane.
A carpet 8 is provided to integrally cover the wide surface of the floor spacer body 9 for resting the driver's feet to improve its appearance, and a carpet 8 is inserted into the floor spacer body 9 so as to protrude from opposite sides of the floor spacer body 9. It consists of a bracket 7. Both end portions 7a and 7b of the bracket 7 are attached to the tunnel portion 41 and the side sill portion 42, which are fixing portions of the vehicle body, with clips, bolts, etc., so that the wide footrest surface of the floor spacer body 9 is at a predetermined height above the floor portion 4. The floor spacer main body 9 has a predetermined thickness so that the floor spacer main body 9 is located at the same position.

Note that the one end 7a of the mounting bracket 7 may be fixed to a console box provided in the tunnel part 41 instead of the tunnel part 41 via a fitting or the like.

In this way, by fixing the floor spacer 6 at a fixed position on the floor 4, the heel point a of the driver 1 becomes higher by the thickness of the floor spacer 6 as shown in FIG. And the position of knee point b also rises. Therefore, in the driving position of the driver 1, the ankle angle A ₃ when depressing the accelerator pedal 2 or the like using the heel point a as a fulcrum becomes larger than in the case where the floor spacer 6 is not used.
Since the knee angle _A2 around knee point b is conversely reduced, the driving position when operating the pedals can be adjusted to the optimum state, especially for short drivers. In other words, in the case of a short person, by using the floor spacer 6, the driving position when operating the pedals can be adjusted to an appropriate state, and the thigh 3 will not be pressurized when pressing the pedals. . Of course, it is preferable that the shorter the height of the driver 1 is, the thicker the floor spacer 6 is used to raise the heel point a.

FIG. 4 shows another embodiment of the floor spacer. This floor spacer 60 is made of a synthetic resin molded body or the like, and has a structure in which an arm 70 serving as a bracket is integrally provided at the center of the mouth end. A substantially L-shaped bent portion 70a is provided at the protruding end of the arm 70, and this bent portion 70a is connected to the mounting portion 4a of the floor 4 via another bracket or the like.
(See FIG. 1) to fix the floor spacer 60.

As described above, the floor spacer 60 may have a shape and hardness that can hold the feet of the driver 1, and the specific structure for attaching it to the floor 4 can be modified in various ways.

<Effects of the Invention> As explained above, according to the vehicle floor spacers 6 and 60 of the present invention, the floor spacer main body 9
is a resin molded product such as chip urethane, which has a wide surface for resting the feet of the driver 1, and has a thickness such that this wide surface for resting the feet is at a predetermined height above the vehicle body floor 4. It is.

Therefore, since the floor spacer body 9 has a wide surface for resting feet, the height of the feet of the driver who operates the various pedals is constant, and the thickness of the floor spacer body 9 can be selected from among various types. By selecting the correct height, the driving position for pedal operation can be maintained in an optimal state even if the driver is shorter than the standard height.
