Description

Bekannt sind Sitze, insbesondere Flugzeugführersitze, welche zwecks Anpassung verschiedener Körperabmessungen an die Bedienungsorgane der Steuerung eines Flugzeuges in ihrer Höhe und in ihrer Längsrichtung einstellbar sind. Die Erfindung bezweckt darüber hinaus, bei einer im wesentlichen gleichbleibenden, durch die Anordnung der Steuerung in engen Grenzen festgelegten Gesamtkörperhaltung die Druckverteilung der belasteten Sitzfläche bei Bedarf zu verändern, um Ermüdungserscheinungen nach längerem Sitzen hinter dem Steuer zu vermeiden.Seats, in particular pilot seats, are known, which are adjustable in height and in their longitudinal direction for the purpose of adapting different body dimensions to the operating elements of the control of an aircraft. The invention also aims to change the pressure distribution of the loaded seat surface if necessary, with an essentially constant overall body posture determined by the arrangement of the control system, in order to avoid symptoms of fatigue after long periods of sitting behind the wheel.

Diese Veränderung kann konstruktiv auf verschiedene Art durchgeführt werden, z.B. bei einem Polstersitz dadurch, dass durch Umlegen eines Hebels etwa Exzenterwellen, auf die sich die einzelnen Polsterfedern unten abstützen, derart verdreht werden, dass gewisse in geeigneter Weise zusammengefasste Federgruppen entspannt und gleichzeitig andere, passend ausgewählte Federgruppen stärker vorgespannt werden. Andere Möglichkeiten sind: Das Kippen der an sich unveränderten Sitzfläche mit oder ohne Veränderung der Rückenlehne und unterteilte Luftkissen o.ä.This change can be carried out structurally in different ways, e.g. in the case of an upholstered seat, by turning a lever about eccentric shafts on which the individual upholstery springs are supported below, so that certain groups of springs combined in a suitable manner are relaxed and others are fitting at the same time selected spring groups are pretensioned more strongly. Other possibilities are: Tilting the unchanged seat surface with or without changing the backrest and subdivided air cushions or similar.

Der Erfindungsgedanke kann sinngemäss auch auf ungepolsterte Sitze, Bände o.ä. angewendet werden. Die Betätigungsarbeit selbst kann durch Körperkraft oder andere Energiequellen geleistet werden.The concept of the invention can also be applied analogously to unpadded seats, volumes or the like. The actuation work itself can be done by physical strength or other energy sources.

Claims (1)

Sitz, im besonderen Führersitz für Kraftfahrzeuge, dadurch gekennzeichnet, dass der Fahrer bei Bedarf, auch während der Fahrt, die Oberfläche des Sitzes über eine geeignete Konstruktion so verändert, dass jeweils bestimmte Muskelpartien des Körpers stärker belastet und gleichzeitig andere entsprechend entlastet werden.Seat, in particular driver's seat for motor vehicles, characterized in that the driver, if necessary, also while driving, changes the surface of the seat via a suitable construction in such a way that certain muscle parts of the body are more heavily stressed and others are relieved accordingly at the same time.
