Adjustable pedal for vehicles

#1. Field of the Invention

#The invention relates to an adjustable pedal for vehicles and machines which can be adjusted to take into account differences in height of individuals who operate and/or drive the machines and vehicles.

#The invention can be used wherever a pedal in vehicles, in particular in motor vehicles or on machines, is to be adjusted in the direction of the operator or driver of the vehicle.

#In the drawings:

#FIG. 1 shows a pedal according to the invention in side view;

#FIG. 2 shows a pedal according to the invention in side view in two positions with the pedal tread pressed in the operating state;

#FIG. 1 shows the pedal 3 according to the invention in side view, comprising the pedal 3, which is fastened at a pedal mounting location to the pedal bracket 1 (FIG. 2) by means of a mounting bolt 2. A mount 4 (FIG. 2) for the Bowden cables can be arranged at the upper end of the pedal 3. The pedal stop 5, which is arranged opposite said mount, cushions the movements of the pedal 3 with respect to the vehicle body. As shown in FIG. 2, a pedal arm guide 6 is arranged in the lower part of the pedal 3 and the pedal arm 7, which can be displaced in the longitudinal direction and at whose end the pedal treadpiece 13 is situated, is fixed in the said guide. The distance between the pedal treadpiece 13 and the pedal mounting can be changed by pulling said pedal arm 7 out or pushing it into the pedal arm guide 6, which can be seen in FIGS. 2 and 3. In order to be able to change its effective length automatically, the pedal arm 7 is provided in its upper part with drive members in the form of teeth 8 of a rack. Engaging in these teeth 8 of the rack are the teeth of the conveying worm gear 10, which is driven in a self-locking manner by means of a servomotor 11, via a drive shaft 12. The servomotor 11 can be arranged within (FIG. 1) or outside (FIG. 3) the passenger compartment. The conveying worm gear 10 together with its drive teeth is arranged in a drive element 9. A slot 14 in the pedal arm 7, into which a screw protrudes, is used for guiding the pedal arm 7. This slot can be seen in particular in FIGS. 2 and 3 and furthermore serves for limiting the displacement of the pedal arm 7.

#FIG. 4 shows a view of the pedal 3 according to the invention together with the pedal treadpiece 13.

#The solution according to the invention has the advantage that the pedal treadpiece 13 can be adjusted in a simple manner with a high degree of safety for the driver with the cost in terms of material and weight being small.
