Claim 3

An apparatus as set forth in claim 1 , wherein said translational structure is a screw.

Claim 4

An apparatus as set forth in claim 2 , wherein said pivot pin is elevated from where said screw is pivotally and threadedly connected to said pedal.

Claim 5

An apparatus as set forth in claim 2 , further comprising means to rotate said screw, wherein rotation of said screw will cause the pedal to longitudinally translate between rearward, a plurality of intermediate, and forward positions.

Claim 6

An apparatus as set forth in claim 2 , further comprising a tie rod disposed between said motion linkage and said screw.

Claim 7

An apparatus as set forth in claim 5 , further comprising an attaching unit disposed about said screw and pivotally attached to said tie rod, attaching unit is fixed in place on said screw by a pair of flanges extending from said screw.

Claim 8

An apparatus as set forth in claim 6 , wherein said body structure includes a second slot for receiving said attaching unit, said second slot includes a front and rear abutment that limits the longitudinal movement of said attaching unit thereby limiting the throw of said pedal.

Claim 9

An adjustable pedal apparatus for a motor vehicle, said apparatus comprising: a pedal having a pivot and a camming formation, said pedal having a static position and a plurality of depressed positions; a body structure including a locking element disposed in a longitudinal manner; a lever including a mating locking element adapted to cooperate with said locking element to hold said pivot of said pedal in a defined location; and a biasing element adapted to encourage cooperation between said locking element and said mating locking element; wherein said camming formation of said pedal is adapted to contact said lever while said pedal is in said static position to eliminate said cooperation between said between said locking element and said mating locking element while allowing cooperation between said locking element and said mating locking element while said pedal is in a depressed position; said pedal includes a pivot pin that defines the pivot of said pedal, and said body structure includes a slot for reception of said pivot pin for limiting vertical movement of said pivot pin.

Claim 10

An adjustable pedal apparatus for a motor vehicle, said apparatus comprising: a pedal having a pivot and a camming formation, said pedal having a static position and a plurality of depressed positions; a body structure including a locking element disposed in a longitudinal manner; a lever including a mating locking element adapted to cooperate with said locking element to hold said pivot of said pedal in a defined location; and a biasing element adapted to encourage cooperation between said locking element and said mating locking element; wherein said camming formation of said pedal is adapted to contact said lever while said pedal is in said static position to eliminate said cooperation between said between said locking element and said mating locking element while allowing cooperation between said locking element and said mating locking element while said pedal is in a depressed position; said pedal includes a pivot pin that defines the pivot of said pedal, and said body structure includes a slot for reception of said pivot pin for limiting vertical movement of said pivot pin.

Claim 11

The apparatus as set forth in claim 8 , wherein said cooperation between said locking element and said mating locking element limits longitudinal movement of said pivot pin.

Claim 12

The apparatus as set forth in claim 8 , wherein said biasing element is disposed between said lever and said pedal.

Claim 13

The apparatus as set forth in claim 8 , wherein said biasing element is a spring that moves longitudinally with said pedal.

Claim 14

An adjustable pedal system for a motor vehicle comprising: a pedal having pivot pin disposed near the top end thereof and a foot pad disposed near the bottom thereof; a body structure having a first longitudinally extending slot formed therein, said first longitudinally extending slot adapted for reception of said pivot pin so that pivot pin can freely slide within said first longitudinally extending slot, said body structure also having a second longitudinally extending slot having an end abutment, said body structure also having a locking element arrangement disposed near said first longitudinally extending slot; a screw element pivotally attached to said pedal at a location below said pivot pin; a spring attached to said screw element and said pedal to provide rotational force therebetween; a motion linkage pivotally attached to said housing at one end thereof; a tie rod pivotally engaged to said motion linkage and to said screw element, said tie rod being pivotally engaged to said screw element via a attaching unit, said second longitudinally extending slot adapted to receive said attaching unit and define the throw of said pedal; motor means to rotate said screw element in order to translate said attaching unit along said screw element, wherein said translation causes said pedal to move in the longitudinal direction thereby causing said pivot pin of said pedal to move in the longitudinal direction within said first longitudinally extending slot; a lever including a mating locking element pivotally connected to said pedal; said pedal including a camming portion at said top end thereof to contact said lever while said pedal is in the static position to eliminate contact between said locking element of said body structure and said mating locking element of said lever to allow said pivot pin to slide freely within said first longitudinally extending slot of said body structure; and a biasing element disposed between said lever and said pedal to establish contact between said locking element of said body structure and said mating locking element of said lever while said lever is depressed.

Claim 15

An adjustable pedal system for a motor vehicle comprising: a pedal having pivot pin disposed near the top end thereof and a foot pad disposed near the bottom thereof; a body structure having a first longitudinally extending slot formed therein, said first longitudinally extending slot adapted for reception of said pivot pin so that pivot pin can freely slide within said first longitudinally extending slot, said body structure also having a second longitudinally extending slot having an end abutment, said body structure also having a locking element arrangement disposed near said first longitudinally extending slot; a screw element pivotally attached to said pedal at a location below said pivot pin; a spring attached to said screw element and said pedal to provide rotational force therebetween; a motion linkage pivotally attached to said housing at one end thereof; a tie rod pivotally engaged to said motion linkage and to said screw element, said tie rod being pivotally engaged to said screw element via a attaching unit, said second longitudinally extending slot adapted to receive said attaching unit and define the throw of said pedal; motor means to rotate said screw element in order to translate said attaching unit along said screw element, wherein said translation causes said pedal to move in the longitudinal direction thereby causing said pivot pin of said pedal to move in the longitudinal direction within said first longitudinally extending slot; a lever including a mating locking element pivotally connected to said pedal; said pedal including a camming portion at said top end thereof to contact said lever while said pedal is in the static position to eliminate contact between said locking element of said body structure and said mating locking element of said lever to allow said pivot pin to slide freely within said first longitudinally extending slot of said body structure; and a biasing element disposed between said lever and said pedal to establish contact between said locking element of said body structure and said mating locking element of said lever while said lever is depressed.
