DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a foot-operated parking brake pedal 10 according to the present embodiment will be described with reference to FIGS.
Will be described. In these drawings, an arrow FR appropriately shown indicates a front side of the vehicle, an arrow UP indicates an upper side of the vehicle, and an arrow IN indicates an interior side of the vehicle.

FIG. 1 is a plan view showing the whole structure of a support structure of a parking brake pedal 10 as a "vehicle pedal", and FIG. 2 is a side view showing the whole structure of the support structure of the parking brake pedal 10. Visually shown.

As shown in these figures, a dash panel 16 is disposed substantially vertically at a position separating the engine room 12 and the vehicle interior space 14. The upper end of the dash panel 16 is welded to a cowl inner panel (not shown) arranged with the longitudinal direction substantially in the vehicle width direction, and the lower end of the dash panel 16 is welded to a floor panel (not shown).

A pedal bracket 18 for swingably supporting the parking brake pedal 10 is disposed behind the dash panel 16 described above. The pedal bracket 18 includes a plate-shaped bracket body 18A. A plate-shaped pedal base 10A constituting the upper end side of the parking brake pedal 10 is pivotally supported on the bracket body 18A so as to swing around the mounting bolt 20. Have been.

A pedal arm 10B extends from the pedal base 10A substantially toward the lower side of the vehicle, and the lower end of the pedal arm 10B serves as a "tread surface" to which the occupant's treading force is applied. Is attached.

On the front end side of the intermediate portion in the height direction of the bracket body 18A of the pedal bracket 18, an arm 18B extending substantially outward in the vehicle width direction along the dash panel 16 is integrally formed. Is formed. A cylindrical collar 22 is provided on the front surface of the tip of the arm 18B.
Is fixed. The fixing bolt 24 is inserted into the shaft core of the collar 22 from the dash panel 16 side, and a nut (not shown) is screwed into the dash panel 16.
It is fixed to.

The arm 1 of the pedal bracket 18
8B corresponds to the “first fixed point” in the present invention, and the first fixed point is substantially equal to the center line CL of the pedal pad 10C of the parking brake pedal 10 by a distance W. It is offset to the outside in the vehicle width direction (see FIG. 1).

On the upper and lower portions on the rear end side of the bracket body 18A of the pedal bracket 18, a cowl side extending substantially upward to the cowl side bracket 26 as a "vehicle side component" is provided. Mounting part 18C and center floor tunnel 28 as "body-side component"
And a floor-side mounting portion 18D extending substantially toward the lower side of the vehicle toward the side surface of the vehicle. The cowl-side bracket 26 is a mounting member welded to the rear end side of the cowl inner panel constituting a part of the cowl described above, and a weld nut 30 is provided at a predetermined position of the cowl-side bracket 26 in advance. Welded.

A cylindrical collar 32 is fixed to the front surface of the cowl-side mounting portion 18C of the pedal bracket 18 described above. The fixing bolt 34 is inserted into the shaft core of the collar 32 from the pedal bracket 18 side and screwed into the weld nut 30, so that the upper portion on the rear end side of the pedal bracket 18 is on the cowl side (that is, the cowl bracket 2).
6).

A long hole 36 for adjusting a mounting position is formed in the floor side mounting portion 18D of the pedal bracket 18 with the longitudinal direction substantially in the vehicle vertical direction. This long hole 36
The weld bolt 38 welded to the center floor tunnel 28 side is relatively inserted into a predetermined position in the
Is screwed into the lower portion on the rear end side of the pedal bracket 18 on the floor side (that is, the center floor tunnel 28).
Side).

In this embodiment, the fixing point of the cowl-side mounting portion 18C of the pedal bracket 18 to the cowl-side bracket 26 and the fixing point of the floor-side mounting portion 18D to the center floor tunnel 28 (these fixing points). A point (corresponding to a "second fixed point" in the present invention) is an axis (one point) which is a substantial rotation center of the pedal bracket 18 when an external force equal to or more than a predetermined value acts on the front part of the vehicle. A chain line P indicates its axis). In the present embodiment, this axis P (when viewed three-dimensionally,
With respect to the axis P and a plane including both the vehicle longitudinal direction passing through the axis P), the above-described first fixing point and the pedal pad 10C are located on the same side in the vehicle width direction.

Note that the "same side in the vehicle width direction with respect to the axis P (the plane)" herein means "the axis P (the plane)" in the case of a right-hand drive vehicle as in the present embodiment.
For the driver's seat front side door side,
In the case of a left-hand drive vehicle, it means "the center floor tunnel 28 side with respect to the axis P (the plane)." In the case of a left-hand drive vehicle, the lower second fixed point is set to a body panel (for example, a dash panel reinforcement) near the intersection of the front pillar and the rocker.

Next, the operation and effect of this embodiment will be described.

To briefly touch the ordinary parking brake operation, when the occupant depresses the pedal pad 10C of the parking brake pedal 10, the parking brake pedal 10 swings around the mounting bolt 20. In addition,
A drum is provided on the pedal base 10A side of the parking brake pedal 10, and a coil spring is wound around the drum. Therefore, when the parking brake pedal 10 is depressed, the coil spring is rotated in a direction in which the coil spring is loosened. You. Therefore, the parking brake pedal 10 is smoothly swung. As described above, when the parking brake pedal 10 is swung, the parking brake cable is pulled in accordance with the swing. As a result, the braking force acts evenly on the left and right rear wheels via the equalizer.

Further, a force in the release direction acts on the drum due to the reaction force of the parking brake cable. Since this force is the same as the winding direction of the coil spring,
The coil spring adheres strongly to the drum and gives a large frictional resistance. For this reason, the parking brake pedal 1
0 is held in the pivoted position. Further, when releasing, the free end of the coil spring is pushed and expanded by the release operation, and the degree of adhesion between the drum and the coil spring is weakened. For this reason, the parking brake pedal 10
Easily returns to its original state.

In addition, in addition to the above configuration, the pedal base 10
Ratchet and bracket body 18A provided on side A
By engaging with the pole lever provided on the side,
A configuration may be adopted in which the parking brake pedal 10 is held at the rocked position.

On the other hand, when an external force equal to or greater than a predetermined value acts on the front portion of the vehicle, the load at that time may be input to the dash panel 16 via a master cylinder or a brake booster provided in the engine room 12. In this case, the dash panel 16 is displaced substantially toward the rear of the vehicle. For this reason,
A load substantially toward the rear of the vehicle acts on the pedal bracket 18 having the first fixed point on the dash panel 16 via the arm portion 18B. In contrast, the pedal bracket 18
The cowl (the cowl-side bracket 26) and the center floor tunnel 28, which are the attachment partners of the second fixed point, have higher rigidity in the vehicle front-rear direction than the dash panel 16, so that these members are almost in the vehicle rear side. No displacement.
Therefore, a relative displacement occurs between the two. Here, in the present embodiment, the cowl-side bracket 26 and the center floor tunnel 28 that are disposed substantially rearward of the dash panel 16 have a second fixing point of the pedal bracket 18, and the second fixing point is Since the first fixed point and the pedal pad 10C of the parking brake pedal 10 are located on the same side in the substantially vehicle width direction, a load substantially toward the rear of the vehicle acts on the pedal bracket 18 as described above. Then, the load is intensively input to the cowl-side mounting portion 18C and the floor-side mounting portion 18D that are the second fixing points of the pedal bracket 18. Therefore, the cowl-side mounting portion 18C and the floor-side mounting portion 18D are plastically deformed, and the pedal bracket 18 is separated from the occupant's leg around the axis P connecting the second fixing points (arrow Q in FIG. 1).
Direction).

As a result, the pedal pad 10C of the parking brake pedal 10 swingably supported by the pedal bracket 18 is also rotationally displaced in the same direction, thereby securing a foot space for the occupant. In other words, according to the present embodiment, when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, control is performed such that the pedal pad 10C of the parking brake pedal 10 is largely displaced away from the occupant's leg. It becomes possible.

In this embodiment, since the second fixed points are set at two positions on the axis P which is the center of rotation of the pedal bracket 18, if the first fixed point of the pedal bracket 18 is also included, There are three support points for the pedal bracket 18 to the vehicle-side component members. As a result, the support rigidity of the parking brake pedal 10 can be improved.

Further, according to the present embodiment, the way of extending the arm portion 18B of the pedal bracket 18 (how to take the offset amount W with respect to the pedal pad 10C, how to take the distance from the dash panel 16, etc.) is tuned. By doing so, there is an advantage that the displacement mode of the pedal bracket 18 and thus the pedal pad 10C of the parking brake pedal 10 can be arbitrarily tuned.

[0041]

On the other hand , the pedal bracket 50 according to the embodiment shown in FIG. 3 has the same structure as the above-described pedal bracket 18 in that it has a bracket body 50A, an arm 50B, and a cowl-side mounting portion 50C. However, the configuration differs from the above-described pedal bracket 18 in that a pair of floor-side mounting portions 50D and 50E are bifurcated and extended from the bracket body 50A toward the center floor tunnel 28 side. I have.

Accordingly, there are two fixed points to the center floor tunnel 28 and three fixed points including the fixed point to the cowl-side bracket 26. Therefore, in the state in which the pedal bracket 50 is assembled to the vehicle body side structural member, since the second fixing point is increased, the support rigidity more of further improvement of the parking brake pedal 10
It is .

[0044] Further, in this embodiment, a pair of notches 51 are formed in the added predetermined position of the floor-side mounting portion 50E, which is a low rigidity only that part. In addition, the diameter of the bolt insertion hole 52 of the floor-side mounting portion 50E is set to be slightly larger than the diameter of the long hole 36 of the original floor-side mounting portion 18D, so that the floor-side mounting portion 18D can be easily removed from the weld bolt 54. Further, 90 volts are provided at the peripheral edge of the bolt insertion hole 52.
Since cross-shaped slits 56 are formed at intervals of degrees,
The rigidity around the bolt insertion hole 52 is low.

Therefore, when an external force equal to or more than a predetermined value acts on the front portion of the vehicle and the above-described load is input to the pedal bracket 50, the floor-side mounting portion 50E buckles (bends) at the location where the pair of notches 51 are formed. ), The periphery of the bolt insertion hole 52 is plastically deformed, and comes off from the weld bolt 54. For this reason, the floor-side mounting portion 50E can be rotationally displaced toward the center floor tunnel 28 (the vertical direction in FIG. 3) . As a result, the pedal bracket 50 can be rotationally displaced around the axis P, and the same effect as in the above-described embodiment can be obtained.

In this embodiment , a pair of notches 51 are formed in the added floor-side mounting portion 50E,
The bolt insertion hole 52 having a diameter slightly larger than the shaft diameter of the weld bolt 54 is formed, and then a cross-shaped slit 56 is formed. However, the present invention is not limited to this. Fixed to the floor side mounting part 50E when acting on
It is only necessary that a function as a fixed function disappearing means (separating means) or a function as a fragile portion can be added, which can eliminate the function as a point . For example, buckling occurs near the bolt insertion hole 52 of the floor side mounting portion 50E. Notch, notch for breakage, thinning around the bolt insertion hole 52, etc.
Various configurations are possible.

In the present embodiment, the second fixed point is set at two upper and lower points so that the axis P is formed from the beginning of the assembly. However, the present invention is not limited to this. Two fixed points may be set.

[0048]

Further, in the present embodiment, the pedal bracket 18 is rotationally displaced around the axis P while the cowl-side mounting portion 18C and the floor-side mounting portion 18D are plastically deformed. However, the present invention is not limited to this. The pedal bracket 18 may be rotationally displaced around the axis P without causing the pedal bracket 18 to rotate. For example, a configuration in which the cowl-side mounting portion 18C and the floor-side mounting portion 18D are formed in advance so that the bearing surface angles are orthogonal to the axis P is applicable.

In the present embodiment, the present invention is applied to the foot-operated parking brake pedal 10. However, the present invention is not limited to this, and may be applied to a vehicular pedal such as a suspended main brake pedal or a clutch pedal. The present invention is also applicable.

[0051]
