Footrest for motor vehicle

The present invention relates to an adjustable footrest connected to a floor structure of a vehicle.

It is known practice for adjustable pedalboxes to be fitted in motor vehicles equipped with automatic gearboxes. The term “adjustable” means that all or part of the pedalbox can be moved closer to or away from the driver's seat in a longitudinal direction so that it is possible to tailor the position of at least part of the pedalbox to the position of the driver's seat, and therefore, to the driver's size.

In particular, adjustable footrests for receiving the left foot of a driver are known. Such footrests can be translated along the longitudinal axis of the motor vehicle to adapt to the position desired by the driver. Known footrests are connected to the floor of a vehicle, in particular, a motor vehicle, and comprise a framework structure having at least one face which is intended to accommodate the foot of a driver and which is inclined toward the front of the vehicle. A mechanism is fixed to the rear of the framework structure, for moving the face. This face-moving mechanism is itself fixed to the floor of the vehicle.

Such currently-known, adjustable footrests are not entirety satisfactory because they do not allow the driver's free leg, which is not exerting any force on the accelerator pedal, to adopt a suitable position.

The object of the present invention is therefore to provide an adjustable footrest which allows the driver of a motor vehicle to position the driver's leg in a suitable position, irrespective of the driver's size, and to provide a motor vehicle which incorporates such a footrest.

To achieve this, the present invention provides an adjustable footrest which is connected to the floor of a vehicle, in particular, a motor vehicle, and which comprises a framework structure including a panel having at least one face which is intended to accommodate the foot of a driver and which is inclined toward the front of the vehicle. A drive mechanism is fixed to the rear of the panel, for moving the face. The drive mechanism is itself fixed to the floor of the vehicle, and is configured for linear displacement along the axis of the vehicle.

Advantageously, the drive mechanism is comprised of a slide and a reduction gearbox designed to move a female part of the slide. The reduction gearbox is preferably fixed to a male part of the slide, and the male part of the slide is preferably fixed to the floor of the vehicle. As a further preference, the terminal part of the output shaft extending from the reduction gearbox is a worm designed to transmit rotary movement to a nut connected to the female part of the slide.

Other advantages and features of the present invention will become better apparent from the detailed description provided below, with reference to the following illustrations.

FIG. 1 is a perspective view of the footrest of the present invention, installed in a motor vehicle and in an extreme retracted position.

FIG. 2 is a longitudinal cross-sectional view of the footrest of the present invention, installed in the motor vehicle and in an extreme deployed position.

FIG. 1 shows an adjustable footrest 1 produced in accordance with the present invention. The adjustable footrest 1 includes a framework structure 2 fixed to portions of the bulkhead of a vehicle, as is shown in FIG. 2 . The framework structure 2 includes a parallelepipedal part 21 directed toward the cabin of the vehicle and toward the floor of the vehicle, and a part 22 having an inclined panel 23 which rests on the floor of the vehicle, as is shown in FIG. 2 .

The panel 23 , which is inclined toward the front of the vehicle, is intended to accommodate the foot of a driver which is not operating the vehicle's clutch pedal. A drive mechanism 3 is provided behind the panel 23 , for linear movement of the framework structure 2 along the longitudinal axis of the motor vehicle.

The base of the drive mechanism 3 is fixed to the floor of the vehicle by screws 31 , and includes a support piece 32 . The upper part of the support piece 32 is machined to form the male part 33 of a slide on which a mating shape (the female part 34 ) can slide. One end of the female part 34 of the slide is fixed to the panel 23 . Welded to the opposite end of the female part 34 is a nut 35 . A worm 4 constituting the terminal part of an output shaft 5 of an angled reduction gearbox 6 slides within the nut 35 so as to transmit the rotary movement of the output shaft 5 to the nut 35 connected to the female part 34 of the slide. The reduction gearbox 6 is controlled by an electric motor (not shown) through a transmission cable 7 connected to the input take-off 51 .

The way in which the above-described device works is as follows. When the driver of the vehicle wishes to move the footrest 1 forward or backward with respect to the driver's seat, to optimize the driver's position, the electric motor is operated, in a manner which is per se known, for example, using an adjustment button. This causes the reduction gearbox 6 to rotate the shaft 5 , in one direction or the other, and within the nut 35 . This then causes the female part 34 of the slide to move, within the male part 33 , causing the framework structure 2 to translate.

Such translational movement of the framework structure 2 makes it possible to satisfactorily provide a footrest which is adjustable according to the size of the driver, allowing good posture in a driving position which is improved, as appropriate, in conjunction with movements of the seat, angling of the backrest, and movements of the steering wheel.
