Abstract
Abstract An adjustment device for an automobile control pedal which is capable of pivotably adjusting the control pedal relative to a datum point, such as the eyelet of a cylinder pushrod. The adjustment device allows the control pedal to be optimally positioned to suit the needs of a particular driver. The preferred 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 link for maintaining a predetermined distance between the pushrod eyelet and the pivot pin of the control pedal. Consequently, the adjustment device can be readily adapted to fit conventional control pedal assemblies without significant modification. The adjustment device includes a camming device which slidably abuts the pedal arm such that rotation of the camming device causes pivotable movement of the pedal arm relative to the datum point. The camming device axis of rotation is preferably 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 cam driving device for rotating the camming device about its axis of cam rotation to produce a corresponding displacement of the control pedal arm about the axis of arm rotation.

Claim 6
Dependent Claim
154 words
An adjustment device for adjusting a pedal arm adapted to rotate about an axis of arm rotation, said adjustment device comprising: camming means rotatably mounted juxtaposed said pedal arm for rotating said pedal arm about said axis of arm rotation, said camming means having an axis of cam rotation; means for locating said axis of cam rotation a predetermined distance from said axis of arm rotation, said locating means having one end pivotably mounted substantially concentric with said axis of arm rotation such that rotation of said camming means rotates said pedal arm about said axis of arm rotation; and drive means juxtaposed said camming means, said drive means having a projecting portion engaging said camming means for driving said camming means about said axis of can rotation; whereby rotation of said camming means about said axis of cam rotation causes said pedal arm to be rotatively displaced about said axis of arm rotation.
Claim 7
Dependent Claim
21 words
The adjustment device of claim 4 wherein said axis of cam rotation is substantially parallel to said axis of arm rotation.
Claim 8
Dependent Claim
33 words
The adjustment device of claim 4 wherein said camming means is a disc having a camming surface radially spaced from said axis of cam rotation, said camming surface slidably contacting said pedal arm.
Claim 9
Dependent Claim
60 words
The adjustment device of claim 4 wherein said means for locating comprises a link extending between said axis of arm rotation and said axis of cam rotation, said link having one end pivotably connected to said pedal arm at said axis of arm rotation and an opposite end pivotably connected to said camming means at said axis of cam rotation.
Claim 10
Dependent Claim
