Abstract
Abstract A resilient unit for biasing the control pedals (such as the friction clutch pedal and/or the brake pedal) of a motor vehicle in which the pedal biasing unit proper is a substantially complete convolution of steel wire, lying on a plane perpendicular to the axis of the pedal pivotal axis. The configuration of the resilient unit is such as to assist the driver both when depressing the pedal and when releasing the pedal, so that the physical effort required of the driver is in any case reduced.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
156 words
A control pedal for motor vehicles including a pedal arm having opposite ends. A pivot for one end of the pedal arm for attachment to the vehicle frame, a pedal plate carried by the other end of the pedal arm, a support means located laterally with respect to the pedal arm, and a preloaded resilient deformable member operatively connected to the support means and the pedal arm serving to diminish the force to be imparted by a driver for depressing the pedal plate and for causing the pedal plate to return to its starting position, said resilient deformable member comprising a single substantially complete convolution of steel having a circular cross-sectional outline, said convolution lying on a plane perpendicular to the axis of the pivot for the pedal arm and having two end points, means rotatably pivoting one end point to the support means, and means rotatably pivoting the other end point to the pedal arm.
Claim 2
Dependent Claim
156 words
A control pedal for motor vehicles including a pedal arm having opposite ends. A pivot for one end of the pedal arm for attachment to the vehicle frame, a pedal plate carried by the other end of the pedal arm, a support means located laterally with respect to the pedal arm, and a preloaded resilient deformable member operatively connected to the support means and the pedal arm serving to diminish the force to be imparted by a driver for depressing the pedal plate and for causing the pedal plate to return to its starting position, said resilient deformable member comprising a single substantially complete convolution of steel having a circular cross-sectional outline, said convolution lying on a plane perpendicular to the axis of the pivot for the pedal arm and having two end points, means rotatably pivoting one end point to the support means, and means rotatably pivoting the other end point to the pedal arm.
Claim 3
Dependent Claim
68 words
The control pedal for motor vehicles as claimed in claim 1 in which each end point is defined by an arm extending normal to the plane of the convolution, one arm extending toward the support means and the other arm toward the pedal arm, and a bushing in each of said support means and pedal arm in which said one arm and said other arm are received respectively.
Claim 4
Dependent Claim
35 words
The control pedal for motor vehicles as claimed in claim 1 in which said other end point is rotatably pivoted to the pedal arm intermediate the pedal plate and the pivot for the pedal arm.
