Abstract

An adjustment device for an automobile control pedal which is capable of pivotably adjusting the control pedal relative to a reaction member, such as the eyelet of a cylinder pushrod for a brake pedal or a flexible cable in case of an accelerator pedal. The adjustment device allows the control pedal to be positioned to suit the needs of a particular driver. The control pedal can be pivotably attached to a frame in any conventional manner, such as with a pivot pin. The adjustment device is mounted alongside the control pedal and to the pushrod eyelet without the need of additional support hardware other than a device for acting on the control pedal. The adjustment device includes a rotatable member for causing pivotable movement of the pedal arm relative to the reaction member. The adjustment device is maintained a predetermined distance from the pivot of the control pedal arm by a spacing device, such as a link. The adjustment device also includes a rotatable driving device for rotating about its axis of rotation to produce a corresponding displacement of the control pedal arm.

Claims41

Dependent claims

An adjustment device for adjusting a pedal arm with respect to a datum point on a reaction member, said pedal arm being rotatable about an axis of arm rotation, said adjustment device comprising:

a link member having a first pivot axis in one end and a second pivot axis in an oppositely disposed other end, said one end of said link member mounted juxtaposed said pedal arm about said axis of arm rotation;
and
means, rotatably mounted to one of said pedal arm and said link member, for rotating said pedal arm about said axis of arm rotation, said rotating means having an axis of rotation complementary with one of said pedal arm and said link member and spaced a predetermined distance from said axis of arm rotation, said predetermined distance being no greater than the distance between said first pivot axis and said second pivot axis, said rotating means further comprising:
a rotatable member mounted about said axis of rotation, said rotatable member having one portion mounted to one of said pedal arm and said link member and another peripheral portion extending in a direction towards the other of said pedal arm and said link member so as to make contact therewith;
means for mounting said rotatable member to said one of said pedal arm and said link member;
and
drive means interconnected with said rotatable member for rotating said rotatable member about said axis of rotation whereby as said drive means rotates said rotatable member said pedal arm is rotated about said axis of arm rotation;
and
means for mounting said datum point of said reaction member to said link member, said mounting means being located on said link member interposed said first pivot axis and said second pivot axis of said link member.
