A centerline of the foot part 5 running from the trailing edge to the leading edge in the drawing is hereinafter referred to as longitudinal axis of the foot called. The seating 2 is shown here for reasons of illustration only schematically in the form of a bracket or frame, on both sides of the Fußteildrehachsen 32 in the form of known pivot joints or the like on the brackets 109 are attached. The main body 103 here consists of two side parts, the side of the pivot joints of Fußteildrehachse 32 attached and with each other by means of cross struts 131 are connected. Furthermore, also pivot joints for the Antriebsanlenkpunkt 31 on both sides of the side parts of the body 103 attached and stand as described above with the Fußteilantriebshebel 30 in articulated connection, in this embodiment of two lateral Fußteilantriebshebeln 30 exists, which are firmly connected to each other (not shown). Also the drive axle 113 is via pivot joints on the footrest drive levers 30 arranged, these pivot joints of the drive axle 113 through the deflection device 115 on both sides via articulated levers 117 are connected.

The deflection device 115 is in this embodiment a rod, which in its center with a connecting lever 116 is provided, over the connection axis 114 with the drive linkage 130 hingedly connected, which consists here for example of a short, flat component, with the rear end of the drive slide 118 is firmly connected, where it is perpendicular to this.

The drive slide 118 is in the direction of the longitudinal axis of the foot part 5 perpendicular to the cross struts 131 on this in its rear section by means of a guide 121 and in its front section by means of an auxiliary guide 122 arranged in a linear manner, one each on a transverse strut 131 attached guide pin 124 and auxiliary guide pins 126 a guide connection between the drive slide 118 and the crossbars 131 and thus the main body of the foot part 5 manufactures.
