Abstract

(57) [Summary] [Purpose] When moving a foot from the accelerator pedal to the top of the brake pedal due to brake operation while traveling in a car, especially an automatic car, the foot is often caught on the right side edge of the brake pedal, and further the lower right corner of the pedal is depressed. You may get stuck in it, but prevent such obstacles and further serious accidents. [Structure] By having a right side surface just below the right edge of the brake pedal, when you move your foot from the accelerator pedal to the top of the brake pedal, the foot slides on this right side without getting caught, making it a smooth brake pedal. Allow your feet to rest.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the shape of an automobile brake pedal.

[0002]

[Prior Art]

 First, an automatic vehicle (hereinafter, automatic vehicle) will be described. A typical automatic vehicle has two pedals under the driver's seat, a right accelerator pedal 2 and a left brake pedal 3, as shown in Figs. 4 and 5 (excluding a footrest). These pedals consist of pedal plates (faces) 8 and 5 and rods 9 and 6, respectively. The stop position of the brake pedal is shallower than that of the accelerator pedal, and is several cm before the driver. In addition, the shape of the brake pedal is long in the horizontal direction, so you can step on it with either your left or right foot (Fig. 4). However, in normal driving, it is premised that the right foot alternates between the two pedals.

In the case of a manual mission vehicle (hereinafter referred to as a manual vehicle), there are differences such as the presence of the clutch pedal (FIG. 8), but details will be described later.

[0004]

[Problems to be solved by the device]

 As mentioned above, the pedal of a normal automatic vehicle has the structure and arrangement shown in Figs. However, with this normal arrangement, the foot movement from the accelerator pedal to the brake pedal is not smooth. This causes the driver to feel a little bit more difficult and painful with the movement of the foot from the accelerator to the brake pedal during normal driving, but the most problematic is the movement of the foot during sudden braking. ..

When sudden braking is required, the driver tries to shift the right foot 1 from the accelerator pedal 2 to the brake pedal 3, as shown in FIG. 5, first moving the foot to the left, and then the foot part. Bends his back and tries to put it on the brake pedal surface (j), but at this time, his foot gets caught at the right end of the brake pedal, and his back cannot be bent, and his foot remains stuck at the lower right of the pedal surface. Or, it may get stuck (k).

This is a very urgent situation in which a sudden sudden braking operation is required, so even if a slight delay in the operation in this situation, for example, a delay of 0.1 seconds, the driver feels fear. Is extremely increased, the calmness is lost, and calm thoughts and operations are completely impossible. The driver, in a situation where his foot is caught under the brake pedal surface, falls into a panic state with an extremely great fear, and loses his normal thinking ability, and his foot is Although I felt a little being caught underneath, I was confused with a strong desire to have my foot on the brake pedal, and I made an operation such as suddenly stepping on the brake, or an escape reflection from fear. Unexpectedly step on. In other words, even though in reality there is a foot under the brake pedal, it leads to the situation of stepping on the foot. However, in this position of the foot, there is a sufficient amount of the part of the foot that remains on the accelerator pedal, and in that state, a very dangerous situation where the accelerator pedal is strongly depressed appears.

[0007] This is a depiction of the actual experience of the present inventor, but it was explained by a general driver as an event that is likely to occur at the time of sudden braking.

In the brake operation accidents of automatic vehicles that have caused many fatal accidents in the past, there are many cases in which the driver explains that the car accelerates despite the brakes being applied. .. It is presumed that, in many cases, as described above, the phenomenon of stepping on the foot while the foot was caught under the brake pedal had occurred. This is because the reason why the brake did not work against sudden acceleration in such an accident is unknown, and no other explanation can be given.

If an accident occurs in the above situation, it means that the accident is caused by a panic situation that is caused by the structure of the vehicle and is easy for the driver to fall into. It can be called unavoidable or force majeure. Also, it can be said that the main cause of such an accident is the catch itself when the foot is moved from the accelerator to the brake pedal in an automatic vehicle. If so, the pedal that causes the foot to be caught is a structural defect of the current automatic vehicle, and if it is recognized as a true structural defect, the automobile is a major player in human life. As mentioned above, the social responsibility of the manufacturer of such a car is heavy.

[0010] In this automatic vehicle, the catching when the foot is moved from the accelerator pedal to the brake pedal is the main problem to be solved by the present invention.

Further, in an automatic vehicle, the movement of the legs will be analyzed in more detail. As shown in FIGS. 6A, 6B, and 6C, if the driver's foot movement from accelerator operation to brake operation is listed in order, p = right foot moves from above the accelerator pedal to the left. q = The foot hits or touches the right end of the brake pedal. r = bend your leg. s = Place your foot on the brake pedal. t = press the brake pedal. That is, (A) or p to r to bend the foot enough to move it to the left. There is also a process (B) in place of the action.

[0012] The method (B) is a well-controlled foot movement both reasonably and reflexively. However, in terms of foot motility, compared with the dorsiflexion of the foot, the plantar flexion of the foot is extremely large, and even when the plantar flexion of the foot at rest is weak, this Doing the dorsiflexion of the foot, on the other hand, makes it a little difficult. Also, during instinctive or reflexive movements, the plantar flexion force acts as an absolutely dominant force, and the dorsiflexion movement may be momentarily impossible. Therefore, as shown in (B), the exercise of moving the accelerator pedal from the accelerator pedal to a brake pedal located a few centimeters in front of the foot while allowing sufficient dorsiflexion of the foot is a strong spine close to the maximum dorsiflexion position. It may be difficult for your legs to feel tired and tired, and it is not a smooth exercise.

Further, in the course of (A), after p to r, instead of s and t, s' = the foot is caught on the lower right side of the brake pedal. t '= bends or bends the foot. The transition (C) is another possible course.

The problem of this branching of s and s', that is, whether it is caught or not, is to eliminate this catch reliably.

A case of a manual mission vehicle (manual vehicle) will be described. As shown in FIGS. 7A and 7B, the pedals of the manual vehicle are arranged in the order of the accelerator pedal 2, the brake pedal 3, and the clutch pedal 4 from the right side. Therefore, the arrangement of the accelerator pedal and the brake pedal is the same as in an automatic vehicle, and it is more thorough than an automatic vehicle in that these two pedals are stepped on with the right foot. However, in the case of manual vehicles, the obstacles such as getting stuck in the foot when moving from the accelerator pedal to the brake pedal, as in automatic vehicles, and the fact that an accident occurs due to a critical situation are rarely seen in society. Seems not to.

One of the reasons is that the difference in the depth of both pedals is generally small in a manual vehicle (Fig. 7-b). Therefore, the dorsiflexion of the foot can be done easily and it is difficult for the foot to be caught between the accelerator pedal and the brake pedal. The other is that in braking, the left foot presses the clutch and the right foot presses the brake pedal, but the left foot presses the clutch pedal, that is, the left foot flexes, causing a somewhat primitive cross reflex of human beings. Since the dorsiflexion of the right foot is promoted, it is possible to make the dorsiflexion of the right foot easier than in an automatic vehicle that does not move the left foot.

Therefore, in the case of a manual vehicle, it is considered that there are originally few obstacles such as getting caught on the legs, but in the future, such obstacles will not necessarily occur for the same reason as automatic vehicles in vehicles to be produced, Having countermeasures against it is meaningful and is the subject of the present invention.

[0018]

[Means for Solving the Problems]

 In order to solve this problem, in the present invention, as shown in FIG. 1, the foot 1 is provided with a right side surface 7 just below the right side edge of the pedal surface 5 of the brake pedal 3 of the automobile. It was designed so that it could slide on its top and bend its legs without getting caught.

According to a first aspect of the present invention, there is provided a brake pedal of an automatic vehicle having a right side surface immediately below a right side edge of the pedal surface. By having the right side under this pedal surface, when transferring the foot from the accelerator pedal to the brake pedal, the foot gets caught on the right side edge of the brake pedal or gets stuck in the lower right side of the pedal like a conventional automatic car. This allows the foot to slide on this right side without slipping in and to rest it smoothly on the brake pedal.

A second aspect of the present invention is a mounting device for a brake pedal, which is mounted on a brake pedal of an ordinary automatic vehicle by welding or bolt fixing so as to have a right side surface below a right side edge of the pedal surface. Similar to item 1, it is possible to move the foot smoothly from the accelerator to the brake pedal.

According to a third aspect of the present invention, in a manual vehicle, the brake pedal has a right side surface below the right side edge of the pedal surface, and has an effect of smoothing the movement of the foot from the accelerator to the brake pedal.

According to a fourth aspect of the present invention, there is provided a brake pedal mounting device which has a right side surface below a pedal surface by being mounted on a brake pedal of an ordinary manual vehicle. Smooth movement of the foot to.

Then, in a strict sense, the brake pedal of an ordinary automobile also has a linear side surface on the edge of the pedal plate, which edge corresponds to something hit by a foot or the like. It has large friction and does not work as a spacer that fills the lower right side of the brake pedal like the right side mentioned in the present invention.Therefore, from a macro perspective, the edge of a normal automobile brake pedal is linear. , The right side mentioned in the present invention does not have meaning.

【Example】

 The present invention will be described below with reference to the embodiments shown in FIGS. These drawings and description are common to claims 1 to 4, and the brake pedal mounting device of claims 2 and 4 is mounted on the brake pedal 3. Further, although the drawing is simplified and the structure such as a pillar for the right side surface 7 under the brake pedal surface 5 is omitted, it is assumed that it actually exists.

In FIG. 2, consider how deep the right side surface 7 below the pedal surface 5 of the brake pedal should be. X is the difference in depth between the brake pedal 3 and the accelerator pedal 2, Y is the amount by which the accelerator pedal is depressed, and W is the distance between the two pedals on the projection plane (a plane parallel to the pedal plane). The depth Z of the right side surface is sufficient if it is approximately X + Y, and is not necessary after that. In addition, Z is actually a value smaller than X + Y due to a trade-off with X, W, etc.

In addition, in addition, the size of the difference X in depth between the brake pedal and the accelerator pedal is also a factor in catching the foot, and it is important to make this an appropriate size for the brake of the present invention. In addition to having the right side under the pedal surface, it is considered to be a condition that should be adopted in future automatic vehicles.

FIG. 3 shows the form of the right side surface 7 below the brake pedal surface 5. The right side of a is perpendicular to the pedal surface, but the right edge of the pedal surface is rounded. In b, the right side surface is inclined from the plane orthogonal to the pedal surface. C has a curved right side.

[0028]

[Effect of the device]

 The present invention makes it possible to move the foot smoothly from the accelerator pedal to the brake pedal without getting caught in the automatic vehicle by providing the right side surface of the lower right side of the pedal surface of the brake pedal with a proper shape. To do. As a result, it is possible to prevent the accidental operation of the brake from developing into a serious accident and surely improve the safety.

Similarly, in a manual vehicle as well, by providing an appropriately shaped right side surface on the lower right side of the brake pedal surface, the movement of the foot from the accelerator to the brake pedal is smoothed to ensure safe driving. It should be
