[0055] In the drawings, reference numerals may be repeated to identify similar and / or identical elements. DETAILED DESCRIPTION

[0056] refer to Figure 1 and Figure 2, an adjustable brake pedal assembly 10 will be described. The adjustable brake pedal assembly 10 includes a double lever 12 having an upper pivot mounting portion 14 and a right pedal mounting portion 16 and a laterally spaced left pedal mounting portion 18. The upper pivot mounting portion 14 is configured to be pivotally mounted to a vehicle structure and connected to a vehicle braking system, as is known in the art. A pedal arm 20 is adapted to be alternately mounted to either the right pedal mounting portion 16 or the left pedal mounting portion 18. A footrest 22 is disposed at the end of the pedal arm 20.

[0057] The double lever 12 and the pedal arm 20 are made of metal. The pedal arm 20 is mounted to either of the pair of laterally spaced lower pedal mounting portions 16, 18 by one or more threaded fasteners. Figure 1 In the embodiment shown in FIG. 1 , the footrest 22 is mounted for "normal" use by a right footed driver. In the second left position (in FIG. 1 ) on the left pedal mounting portion 18, the footrest 22 is mounted for "normal" use by a right footed driver. Figure 2 ), the footrest 22 is mounted for use by a left footed driver. The right side pedal mounting portion 16 and the left side pedal mounting portion 18 are equally spaced from the rotation axis of the upper pivot mounting portion 14 so that in either position, the footrest 22 is an equal distance from the rotation axis.

[0058] The position is divided into two levels in order to provide a more comfortable position for disabled people who drive with their left foot. Due to the nature of the brake pedal, it is pressed hard in an emergency, so a rigid pedal design is required and the two-stage brake pedal has the possibility to move more to the left while maintaining a solid structural design. In order to meet the footrest regulations, a spacing of 50 mm must be maintained from the footrest. The two-stage brake pedal is available for left-foot drivers with freedom in the existing position and in a position further to the left.

[0059] refer to Figure 3 and Figure 4, the adjustable accelerator pedal assembly 30 will be described. The adjustable accelerator pedal assembly 30 includes an upper lever arm 32 having an upper pivot mounting portion 34. An intermediate link 36 includes an upper end pivotally mounted to the upper lever arm 32 by a first pivot joint 38. A pedal arm 40 includes an upper end mounted to a lower end of the intermediate link 36 by a second pivot joint 42 and includes a foot pedal 44 at a distal end. A first gear segment 46 is mounted to the upper lever arm 32. The intermediate link 36 includes an upper gear segment 48 in meshing engagement with the first gear segment 46. A lower gear segment 50 on the intermediate link 36 is in meshing engagement with a second gear segment 52 mounted to the pedal arm 40. The upper gear segment 48 is rotatable about the first pivot joint 38. The second gear segment 52 is rotatable about the second pivot joint 42. The first pivot joint 38 and the second pivot joint 42 are parallel to each other.

[0060] The lateral position of the footrest 44 can be adjusted relative to the upper lever arm 32 by pivoting the first pivot joint 38 and the second pivot joint 42. Figure 5 , the adjustable pedal system can be applied to the brake pedal 10 and the accelerator pedal 30. For the brake pedal assembly 10, two positions are possible, including a "normal" or traditional use position, and a position moved to the left for drivers with a left foot. According to regulations, the brake pedal assembly 10 is required to be 50 mm from the pedal board. For the accelerator pedal 30, gear joints 38 and 42 are used to adjust the position of the foot pedal 44. Bolts can be used to tighten the joints 38 and 42 in place. The first joint 38 in the double joint structure allows the pedal 44 to move in the desired direction, and the second joint 42 allows the pedal to move the position of the foot so that it can be operated.

[0061] In order to allow disabled people who need to use their left foot to drive, a special device must be installed on the left side. If so, there is a risk of sudden accidental acceleration in the case where the changed pedal position is unfamiliar. In addition, it is possible to adjust the position of a driver who drives with his right foot and has difficulty driving in the existing pedal position due to his body structure, so that they can drive comfortably. Since each person's body structure is different, the original pedal position may be inconvenient. The device of the present disclosure can provide convenience by adjusting the pedal to a convenient position not only for disabled drivers who use their left foot but also for people who are uncomfortable driving in the existing pedal position.

The broad teachings of the present disclosure can be implemented in various forms. Therefore, although the present disclosure includes specific examples, the true scope of the present disclosure should not be so limited, because other modifications will become apparent when studying the drawings, the specification and the following claims.
