Abstract
Abstract A cable is mounted on a winding drum coupled with the output shaft of a reversible motor which is caused to rotate by control means when an operating parameter of the vehicle exceeds or goes below a predetermined value. The cable is kept taut and its free end is connected by resilient means to a mobile member which is connected to the accelerator control linkage.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
In a vehicle having an accelerator pedal, an accelerator control linkage, and an accelerator pedal return apparatus comprising a reversible motor, control means for causing the motor to rotate when an operating parameter of the vehicle exceeds or goes below a predetermined value, a first mobile member connected to the accelerator control linkage, a second mobile member controlled by the reversible motor, and resilient means connecting the first mobile member to the second mobile member: the improvement comprising a winding drum coupled with an output shaft of the reversible motor, the second mobile member being a cable which is mounted on the winding drum and whose free end is connected to the first mobile member by the resilient means, and means for applying tension to the cable, said first mobile member being a lever pivotally connected at one end to the accelerator control linkage and supported for pivotal movement about a fixed axis located between said end and the point of connection of said resilient means.
Claim 2
Dependent Claim
166 words
In a vehicle having an accelerator pedal, an accelerator control linkage, and an accelerator pedal return apparatus comprising a reversible motor, control means for causing the motor to rotate when an operating parameter of the vehicle exceeds or goes below a predetermined value, a first mobile member connected to the accelerator control linkage, a second mobile member controlled by the reversible motor, and resilient means connecting the first mobile member to the second mobile member: the improvement comprising a winding drum coupled with an output shaft of the reversible motor, the second mobile member being a cable which is mounted on the winding drum and whose free end is connected to the first mobile member by the resilient means, and means for applying tension to the cable, said first mobile member being a lever pivotally connected at one end to the accelerator control linkage and supported for pivotal movement about a fixed axis located between said end and the point of connection of said resilient means.
Claim 3
Dependent Claim
17 words
The improvement according to claim 1, wherein said resilient means comprises a calibrated spring with contiguous turns.
Claim 4
Dependent Claim
121 words
The improvement according to claim 1, further comprising a computer having two output terminals, the computer emitting a control signal at a respective one of its output terminals when said operating parameter of the vehicle respectively exceeds or goes below a predetermined value, two relay switches each having an excitation coil and a contactor positioned selectively between earth or a current source and a respective input terminal of the motor, two limit switches each positioned between a respective output terminal of the computer and the excitation coil of a respective relay switch, and a rotatable member which at each of two rotational positions opens a respective one of the limit switches, the rotatable member being rotationally coupled to the winding drum.
