JP 2016-71618 A

When the pedal pad described in Patent Document 1 is a brake pedal pad, when the accelerator pedal is switched to the brake pedal, the driver's right foot (for example, the shin-side metatarsal portion of the right foot) is placed in the groove portion with respect to the brake pedal pad. Since the trajectory is drawn so as to intersect with the grooves in the area, it is difficult to perform the step change operation smoothly. Further, in the pedal pad described in Patent Document 1, the length of the projection region in the direction intersecting with the longitudinal direction of the sole of the driver's shoe (foot sole) is short, so that the sole of the driver's foot easily slips.

SUMMARY OF THE INVENTION Accordingly, one of the objects of the present invention is to provide a brake pedal pad that allows smooth pedal operation.

A brake pedal pad according to one aspect of the present invention is a brake pedal pad having a tread surface, wherein a straight imaginary line is drawn along the vehicle front-rear direction so as to pass through the center of the brake pedal pad in the vehicle width direction. In this case, the tread has an arcuate first groove provided centering on a point set on the vehicle width direction right side of the imaginary line and on the vehicle rear side of the brake pedal pad.

As an example of the brake pedal pad, there is a form provided with a second groove that intersects with the first groove.

The brake pedal pad has an arcuate first groove. The first groove portion is provided in an arc shape substantially along the trajectory of the driver's right foot when stepping on the brake pedal from the accelerator pedal. Therefore, according to the above-mentioned brake pedal pad, it is possible to impart an appropriate amount of slippage to the sole of the driver's foot in the width direction of the sole when the foot is changed from the accelerator pedal to the brake pedal. Due to this moderate slippage, it is possible to smoothly switch from the accelerator pedal to the brake pedal. The arc of the first groove extends in a direction that intersects the longitudinal direction of the sole of the driver's foot when the brake pedal is depressed. Therefore, according to the brake pedal pad, when depressing the brake pedal, it is possible to apply an appropriate amount of friction to the sole of the driver's foot in the longitudinal direction. This moderate friction can prevent the soles of the driver from slipping when depressing the brake pedal. As described above, the brake pedal pad allows smooth pedal operation.

Since the brake pedal pad has the second groove portion in addition to the first groove portion, the pedal operation can be performed more smoothly. The second groove is provided so as to cross the first groove. Therefore, according to the brake pedal pad provided with the second groove portion, it is possible to apply appropriate friction to the sole of the driver in the width direction of the sole when stepping on the brake pedal from the accelerator pedal. This moderate friction makes it easier for the sole of the driver's foot to stop at a suitable position on the tread surface of the brake pedal pad. By intersecting the first groove, the second groove substantially follows the longitudinal direction of the sole of the driver's foot when stepping on the brake pedal. Therefore, according to the brake pedal pad having the second groove, the first groove provides appropriate friction to the sole of the driver's foot when stepping on the brake pedal, while the second groove provides appropriate friction to the sole of the driver's foot. By giving a good slipperiness, the brake pedal can be stepped on smoothly.

Furthermore, in FIG. 1, the driver's right foot 300 when operating the accelerator pedal 200 is indicated by a two-dot chain line. In this example, the right leg of a Japanese male of average height among adult Japanese males (hereinafter referred to as a 50% physique model Japanese male) will be described as an example.

The brake pedal pad 1 of the embodiment has a first groove portion 11 on a tread surface 10 . The brake pedal pad 1 in this example further includes a second groove portion 12 on the tread surface 10 . The tread surface 10 is a curved surface with a convex surface.

[First groove]
The first groove portion 11 is an arcuate groove. When a linear imaginary line 2 is drawn along the vehicle front-rear direction so as to pass through the center of the brake pedal pad 1 in the vehicle width direction, this arc is on the right side of the imaginary line 2 in the vehicle width direction and the brake pedal pad 1. A point set on the rear side of the vehicle is provided as the center O. The right side of the virtual line 2 in the vehicle width direction is the accelerator pedal 200 side. When viewed in the vehicle width direction, the center O is further set to the vehicle width direction right side of the right edge of the brake pedal pad 1 (brake pedal 100). Further, if a straight imaginary line is drawn along the vehicle front-rear direction so that the center O passes through the center of the accelerator pedal 200 in the vehicle width direction, the imaginary line 2 of the brake pedal pad 1 (brake pedal 100) and the accelerator For example, it may be set on the vehicle width direction right side of the midpoint of the line segment connecting the virtual line of the pedal 200 . On the other hand, the center O is set on the left side of the left edge of the accelerator pedal 200 in the vehicle width direction. Further, the center O may be set on the left side in the vehicle width direction of the midpoint of the line connecting the right edge of the brake pedal pad 1 (brake pedal 100) and the left edge of the accelerator pedal 200. mentioned. When a straight imaginary line is drawn along the vehicle width direction so that the center O passes through the center of the brake pedal pad 1 (brake pedal 100) in the vehicle front-rear direction when viewed in the vehicle front-rear direction, For example, the length is set within a range of about ±10% of the predetermined length. The predetermined length is the length of the metatarsal from the heel of the driver's right foot 300 to the shin-side metatarsal point.

The number of first grooves 11 may be one, or two or more. The arc shape of the first groove portion 11 is set by either of the following two methods.

(1) When the accelerator pedal 200 is operated, the radius is the length of the line segment 3 connecting the heel of the driver's right foot 300 and the shin-side metatarsal point, and the position of the heel at that time is the center O. do. The driver's right foot 300 is rotated with the center O as a base point. The trajectory 4 of the right leg 300 on the shin side of the driver at this time is used as a reference. This form assumes that the driver switches from the accelerator pedal 200 to the brake pedal 100 while the heel of the driver's right foot 300 is fixed.

(2) A fixed point on the accelerator side corresponding to the shin-side middle foot point of the driver's right foot 300 when operating the accelerator pedal 200, and a shin-side center of the driver's right foot 300 when operating the brake pedal 100 The fixed point on the brake side corresponding to the foot portion is statistically determined to some extent. Therefore, a statistically predicted fixed point on the accelerator side and a fixed point on the brake side are determined in advance. The radius is the length of the line segment 3 connecting the heel and the shin-side metatarsal point of the driver's right foot 300 when the accelerator pedal 200 is operated. Draw an arc to pass through the fixed point on the accelerator side and the fixed point on the brake side. This arc (trajectory 4 by the shin-side metatarsal point of the driver's right foot 300) is used as a reference. This form assumes that the driver switches from the accelerator pedal 200 to the brake pedal 100 while the heel of the driver's right foot 300 is lifted. In this example, the first groove portion 11 is set using this configuration.

The first groove portion 11 is an arcuate groove that is concentric with the locus 4 set by (1) or (2) above. When a plurality of first groove portions 11 are provided, a plurality of arc-shaped grooves concentric with the trajectory 4 may be provided.

The first groove portion 11 is formed by projecting the trajectory of the driver's right foot 300 (range from the heel to the toe) on the brake pedal pad 1 when stepping on the brake pedal 100 from the accelerator pedal 200 (hereinafter referred to as the projection area). ). The first groove portion 11 may be provided at least in the projection area, and may be provided in areas other than the projection area. In this example, a plurality of first grooves 11 are provided over the entire tread surface 10 of the brake pedal pad 1 .

The radius of the first groove portion 11 is 90 mm or more and 330 mm or less. The radius of the first groove portion 11 is based on, for example, the length of the metatarsal bone from the heel of the driver's right foot 300 to the shin-side metatarsal point. Specifically, when using the right foot of a Japanese man with a physique model of 50%, the standard is 188 mm. When a plurality of first groove portions 11 are provided, it is preferable that any of the first groove portions 11 satisfy the above range. When the radius of the first groove portion 11 satisfies the above range, it is easy to improve the smoothness of the pedal operation. Further, the radius of the first groove portion 11 is 130 mm or more and 250 mm or less, particularly 160 mm or more and 210 mm or less.

Since the width of the first groove portion 11 is 0.5 mm or more, the inside of the first groove portion 11 is less likely to be clogged with stones or water, and even if it is clogged, it can be easily discharged. On the other hand, since the width of the first groove portion 11 is 10 mm or less, it is easy to secure a contact area between the brake pedal pad 1 and the sole of the driver's foot. Further, the width of the first groove portion 11 is 1 mm or more and 5 mm or less, particularly 1.5 mm or more and 3 mm or less.

When a plurality of first grooves 11 are provided, the first grooves 11 may be provided at regular intervals, or regions with different intervals may be provided. The interval between adjacent first groove portions 11 is 0.5 mm or more and 150 mm or less. The interval between the first grooves 11 here is the interval between the edges of the adjacent first grooves 11 . When the distance is 0.5 mm or more, it is easy to secure a contact area between the brake pedal pad 1 and the sole of the driver's foot. On the other hand, when the interval is 150 mm or less, it is easy to secure the width of the first groove portion 11, the inside of the first groove portion 11 is less likely to be clogged with stones or water, and even if it is clogged, it is easy to discharge. Further, the distance is 4 mm or more and 20 mm or less, particularly 6 mm or more and 10 mm or less.

[Second groove]
The second groove portion 12 is a linear groove that intersects with the first groove portion 11 . The number of second grooves 12 may be one, or two or more. When the brake pedal 100 is operated, the point (fixed point) at which the shin-side metatarsal portion of the driver's right foot 300 is positioned on the brake pedal 100 is statistically determined to some extent. For example, when the driver's right foot 300 operates the brake pedal 100, the shin-side metatarsal point of the driver's right foot 300 is at the fixed point. For example, a straight line connecting the midfoot point portion may be used as a reference. The second groove portion 12 is a groove parallel to the reference straight line. When a plurality of second groove portions 12 are provided, a plurality of linear grooves parallel to the reference straight line may be provided.

The second groove portion 12 is provided so that the angle between the extension line of the second groove portion 12 and the imaginary line 2 (the angle θ shown in FIG. 1) is greater than 0° and less than or equal to 45°. When the angle θ satisfies the above range, it is easy to improve the smoothness of the pedal operation. The angle θ is further 2° or more and 35° or less, particularly 10° or more and 25° or less.

The width of the second groove portion 12 is 0.5 mm or more and 10 mm or less. The width of the second groove portion 12 here is the width of the opening of the second groove portion 12 . Since the width of the second groove portion 12 is 0.5 mm or more, the inside of the second groove portion 12 is less likely to be clogged with stones or water, and even if it is clogged, it can be easily discharged. On the other hand, since the width of the second groove portion 12 is 10 mm or less, it is easy to secure a contact area between the brake pedal pad 1 and the sole of the driver's foot. Further, the width of the second groove portion 12 is 1 mm or more and 5 mm or less, particularly 1.5 mm or more and 3 mm or less.

When a plurality of second grooves 12 are provided, the second grooves 12 may be provided at equal intervals, or regions with different intervals may be provided. The interval between adjacent second groove portions 12 is 0.5 mm or more and 150 mm or less. The interval between the second groove portions 12 here is the interval between the edge portions of the adjacent second groove portions 12 . When the distance is 0.5 mm or more, it is easy to secure a contact area between the brake pedal pad 1 and the sole of the driver's foot. On the other hand, when the interval is 150 mm or less, it is easy to secure the width of the second groove portion 12, and the inside of the second groove portion 12 is less likely to be clogged with stones or water. Further, the distance is 4 mm or more and 20 mm or less, particularly 6 mm or more and 10 mm or less.

[Action/effect]
The brake pedal pad 1 has an arcuate first groove portion 11 substantially along the trajectory 4 of the driver's right foot 300 when stepping on the brake pedal 100 from the accelerator pedal 200 . Therefore, the driver's right foot 300 can easily move along the first groove portion 11, and the pedal can be smoothly changed. On the other hand, when operating the brake pedal 100, the first groove portion 11 should be along the direction that intersects the longitudinal direction of the sole of the driver's foot (the direction from the heel to the toe) when stepping on the brake pedal 100. become. Therefore, when depressing the brake pedal 100, it is possible to apply an appropriate amount of friction to the sole of the driver's right foot 300, thereby suppressing slipping of the sole of the driver.

The brake pedal pad 1 has a second groove portion 12 intersecting with the first groove portion 11 . The second groove portion 12 has a function that is mainly opposite to that of the first groove portion 11 . Specifically, the second groove portion 12 intersects the trajectory 4 of the driver's right foot 300 when stepping on the brake pedal 100 from the accelerator pedal 200 . Therefore, the driver's right foot 300 is moderately easily caught in the second groove portion 12 when stepping on the brake pedal 100 from the accelerator pedal 200 . Further, when the brake pedal 100 is stepped on, the second groove portion 12 extends along the longitudinal direction of the sole of the driver's foot when stepping on the brake pedal 100 . Therefore, when depressing the brake pedal 100, the sole of the driver's foot is moderately slippery.

The brake pedal pad 1 has the following effects by providing the first groove portion 11 and the second groove portion 12 having contradictory functions. First, when stepping on the brake pedal 100 from the accelerator pedal 200, the stepping operation of the pedal can be smoothly performed by the first groove portion 11, and the second groove portion 12 allows the sole of the driver's foot to be placed on the tread surface 10 of the brake pedal pad 1. It can be easily stopped at a suitable position on the top. Next, when depressing the brake pedal 100, the first groove portion 11 prevents the sole of the driver's foot from slipping too much, and the second groove portion 12 allows smooth depressing operation.
