Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a device for adjusting the lateral position of a pedal in a vehicle.

2. Description of the Related Art Vehicles are equipped with various pedals such as a brake pedal, an accelerator pedal, and a clutch pedal, and the occupant controls various mechanisms by depressing these pedals. Such a pedal is supported so as to be rotatable through a predetermined angle so as to achieve its original purpose, but its mounting position is fixed and cannot be moved. However, since each occupant's body structure is different, if the pedal position is fixed, not all occupants will be able to operate the pedal in the position that is most convenient for them, and in some cases it may be a little impossible to operate the pedal. Sometimes you are forced to take a different stance. Additionally, in addition to normal driving operations, some occupants may also perform a special driving operation called heel-and-toe, but the pedals are pre-installed in a predetermined position suitable for normal driving operations. If you are sitting in a comfortable position, you may not be able to perform special driving operations with a satisfactory posture.

Therefore, a pedal lateral position adjustment device has been proposed in which the pedal is supported movably in the substantially lateral direction of the vehicle and its position can be adjusted. Tighten the nut that fixes the screw, and then tighten the nut again after adjustment, which is a cumbersome operation.

Object The object of the invention is to provide a device for adjusting the lateral position of a pedal in a vehicle, which eliminates the above-mentioned conventional drawbacks.

Configuration In order to achieve the above object, the present invention includes a shaft extending substantially transversely to the direction of travel of the vehicle and rotatably but immovably supported relative to the vehicle body, and a shaft formed on the shaft. a nut that is threaded onto each screw and moves in the axial direction of the shaft as the shaft rotates; a sliding bracket fixed to the nut; and a drive device that rotationally drives the shaft; A device for adjusting the lateral position of a pedal in a vehicle is proposed, characterized in that the arm of the pedal is supported to be rotatable relative to the sliding bracket but not relatively movable in the lateral direction.

Operation The drive unit is actuated to rotate the shaft, thereby moving the nut together with the sliding bracket in the axial direction of the shaft, that is, generally in the lateral direction of the vehicle, thereby adjusting the lateral position of the pedal.

Embodiment Hereinafter, an embodiment in which the present invention is applied to a brake pedal will be described with reference to the drawings.

FIG. 1 is a side view showing an example of a brake pedal and how it is attached, and FIGS. 2 and 3 are cross-sectional views thereof. Reference numeral 1 indicates a pedal bracket fixed to a vehicle body (not shown). A shaft 2 extending in a direction Y (FIG. 2) substantially transverse to the traveling direction X (FIG. 1) of the vehicle is rotatably supported by the bracket 1 via bearings 3 and 4. In this way, although the shaft 2 is rotatable relative to the vehicle body, it is supported in an immovable position. A sliding bracket 7 is supported in the central region of the shaft 2 via a nut 5 and a sliding bearing 6. A nut 5 and a sliding bearing 6 are fixed to a sliding bracket 7.

Reference numeral 8 designates a brake pedal according to the present invention, and this pedal 8 consists of a footplate 13 (see FIG. 4) on which an occupant applies a pedal force with his or her foot, and a pedal arm 9 integrally connected to the footplate 13 (see FIG. 4). A pivot pin 10 extending in the lateral direction Y is fixed to the upper end of the pedal arm 9.
End members 11 and 12 are screwed onto each end of the pin 10, and these end members are connected to a sliding bracket 7.
is rotatably supported. In this way, the arm 9 of the pedal 8 is rotatable with respect to the bracket 7, but is supported so as not to be relatively movable in the lateral direction Y.

When the occupant depresses the footplate 13 of the brake pedal 8 and applies some operating force, the pedal 8 moves to the first position.
It rotates in the direction indicated by arrow A in the figure.

Further, as shown in FIGS. 4 and 5, a pin 14 is fitted into the pedal arm portion between the pivot pin 10 and the footboard 13 so as to be rotatable relative to the pedal arm 9. Both supporting parts 1 of the connecting member 15 are formed in a substantially U-shape at each end.
It is fixed at 5a. Pedal arm 9 is pin 1
4 in its longitudinal direction (lateral direction Y). An operating rod 16 is fixedly connected to the connecting member 15, and the other end of the operating rod 16 is connected to a master cylinder 17 that constitutes a brake system. Therefore, when an operating force is applied to the brake pedal 8 and it is rotated in the direction of arrow A, this operating force is applied to the pin 14, the connecting member 15, and the actuating rod 16.
This force is transmitted to the master cylinder 17 via the hydraulic pressure, and this force is converted into hydraulic pressure to operate the brake. When the operating force applied to the brake pedal 8 is released, the pedal 8 returns to its original position by the action of a return spring 18 whose ends are locked to the connecting member 15 and the vehicle body.

The brake pedal 8 can be operated as described above, but since the conventionally known pedal 8 has a fixed mounting position as described above, the position of the pedal is optimal for all occupants. It doesn't necessarily have to be something. Therefore, in the pedal lateral position adjustment device according to the present invention shown in the drawings, the pedal 8 is supported so as to be adjustable in a direction Y transverse to the running direction, and is configured to be able to adjust and move the pedal to a desired position. has been done. Its specific configuration is as follows.

A gear 19 is fixed to one end of the shaft 2 as shown in FIGS. 1 and 2, and another gear 20 meshes with this gear 19, and this gear 20 is supported by the pedal bracket 1 Output shaft 2 of motor 21
It is fixed at 1a. Further, a thread 2a is cut in a part of the shaft 2, and a female thread 5a of a nut 5 is screwed into this male thread. For this reason, the motor 21
When the shaft 2 is rotated by operating the gears 19 and 20, the nut 5 screwed onto the shaft 2 moves in the axial direction of the shaft 2, that is, in the lateral direction Y, and Accordingly, the sliding bearing 6 is connected to the shaft 2.
The sliding bracket 7 and the brake pedal 8 move in the lateral direction Y. Thus, when the occupant desires, by operating the motor switch (not shown), the brake pedal 8 is actuated in the lateral direction Y by the desired amount, and the brake pedal 8 is actuated in the lateral direction Y by the desired amount to provide the optimum movement for the occupant's physique or for special driving maneuvers. The brake pedal 8 can be brought into a suitable lateral position. The pedal bracket 1 also has a guide rod 22 extending parallel to the shaft 2, as shown in FIG.
is fixed, and a sliding bracket 7 is attached to this rod 22.
are slidably fitted. Therefore, the sliding bracket 7 and the brake pedal 8 can move while being reliably guided by the guide rod 22 without any loose movement.

When the brake pedal 8 is actuated in the lateral direction Y as described above, its pedal arm 9 slides against the aforementioned pin 14 shown in FIG. , the movement of the brake pedal 8 is not hindered by the master cylinder 17. The distance B between each support portion 15a of the connecting member 15 and the pedal arm 9 in the neutral position in the lateral direction is set to be greater than or equal to the maximum movement amount of the brake pedal 8 to prevent interference between the pedal arm 9 and the connecting member 15. It goes without saying that this should be prevented.

Although a motor is used to operate the pedal in the above embodiment, a driving device such as a solenoid or a hydraulic cylinder may be used instead. Furthermore, it goes without saying that the present invention can be applied not only to brake pedals but also to accelerator pedals, clutch pedals, etc.

Effects According to the present invention, the pedal can be adjusted in a direction substantially transverse to the direction in which the vehicle is traveling, and therefore the position of the pedal can be set according to the physique of the occupant or the purpose of driving. Moreover, the position of the pedal can be adjusted simply by operating the drive device, making the operation very easy.
