Description

Transport vehicle seat comprising a foot rest Technical Field The present invention relates to a vehicle seat. The invention also relates to a vehicle, in particular a motor vehicle, comprising at least one such vehicle seat. Background Increased comfort in vehicles, particularly in motor vehicles, has led to a desire for a lounge chair with a foot rest. Especially in future autopilot vehicles, the vehicle occupants will be able to take advantage of travel time in the vehicle to rest and relax and expect the presence of such comfortable seats. Maximum comfort is achieved if the foot can be supported when the leg is supported. In contrast, if the support is made only in the lower leg region, fatigue phenomenon occurs rapidly. Often, the adjustment travel of the support directly provided on the lower seat part is not sufficient to reach the position required for supporting the foot or the operating kinematic mechanism must be constructed very firmly, which would result in significant additional costs and additional weight. A vehicle seat is known from DE 10 2010 012 767 A1, which comprises a foot rest having a support plate arranged in front of the vehicle seat and movable relative to the vehicle bottom for the feet of an occupant sitting on the vehicle seat. The support plate may be inclined upwardly about a transverse axis on the other seat side end to face away from the seat end. The slide is guided displaceably on the longitudinal side of the support plate and is connected to the vehicle seat by a flexible support element for the lower leg of the passenger. A foot support for a vehicle is known from DE 10 2005 013 170 A1, which has a support plate for the lower leg of an occupant sitting on a vehicle seat, is arranged in front of the vehicle seat and can be pivoted out of a vertical storage position below the front edge of the vehicle seat into a horizontal support position in which the support plate can be moved out telescopically. DE 10 2004 050 730 A1 shows and describes a vehicle seat assembly in an aircraft with vehicle seats arranged one behind the other, wherein a flexible and roll-like, rear-extractable support part arranged below the front-row seats can be mounted on the seat bottom of the seat lying behind it and forms a support for the feet and lower legs of an occupant sitting on the rear-row seat in the mounted state. FR 2 906 A1 shows and describes a vehicle seat comprising a foot rest which can be moved out of a stowed position under the vehicle seat telescopically forward by means of a rail assembly arranged under the seat and can be tilted about a transverse axis. Disclosure of Invention The object of the invention is to provide an improved vehicle seat comprising a foot rest which can be stowed under the vehicle seat in a space-saving manner when not in use. In a vehicle seat which solves this object and comprises a foot rest, a lower seat part with a seat surface and a backrest with a backrest surface, the lower seat part is preferably coupled or couplable in a longitudinally movable manner to a vehicle structure, the foot rest with a bearing surface is movable between a stowed position and a use position and is arranged in front of the lower seat part in the use position, it is provided according to the invention that the foot rest has a first edge facing away from the lower seat part and a second edge facing the lower seat part and at least one longitudinal carrier extending from the first edge to the second edge, which is connected in the region of the first edge with a first guide element of the operating mechanism, which is guided in a longitudinally movable manner in a guide rail of the operating mechanism, which is arranged in front of the lower seat part and extends away from the lower seat part, which is pivotably connected in the region of the second edge with an operation belonging to the operating mechanism about a first transverse axis, and which the lever or the operating mechanism can be pivoted about a second transverse axis relative to the lower seat part by means of an actuating device. Advantages are that The foot support according to the invention is arranged in the moved-in state below or in front of the vehicle seat, in particular of the front region of the lower seat part. By means of the guide rail, the support surface of the foot rest can be brought into the use position in the event of a movement away from the vehicle seat, for example forward, in the longitudinal direction of the vehicle. Advantageously, the first guide element, which is arranged longitudinally displaceably in the guide rail, can be displaced along the guide rail by means of an actuator device which can be driven by the drive element. The longitudinal adjustment of the support surface can thus be carried out non-manually by means of the actuator device. In this case, the drive element is preferably formed by an electric motor and the actuator device is preferably formed by a screw drive. The s
