Description
Eingebaute und verstellbare Rückenstütze für Lehnen von Motorfahrzeugen Es ist bekannt, dass die meisten Rückenpolster der Motorfahrersitze den anatomischen Bedingungen der jeweils Sitzenden nicht in dem Masse entspre chen, wie dies der Fall sein sollte.
Es ist fernerhin bekannt, dass durch solch schlechte Rückenpolster speziell Motor- sowie Mit fahrer an ihren Wirbelsäulen Schäden erleiden, wobei auch frühzeitige Ermüdungserscheinungen auftreten.
Vorliegende Erfindung betrifft nun eine einge baute und vertikal verstellbare Rückenstütze für Lehnen von Motorfahrzeugen. Sie ist dadurch ge kennzeichnet, dass dieselbe in einer U-Profilschiene gleitend nach oben und nach unten bewegt werden kann, was jedem Motor- oder Mitfahrer ermöglicht, die beste Stützlage selbst den anatomischen Verhält nissen seiner Wirbelsäule derart anzupassen, dass obgenannte Schäden und Ermüdungserscheinungen nicht mehr auftreten können.
Es kann die verstellbare Rückenstütze mittels eines Kettenantriebes, eines Drahtzuges oder einer Gewindestange verstellbar sein.
In der Zeichnung ist eine beispielsweise Ausfüh rungsform des Erfindungsgegenstandes dargestellt. Fig. 1 zeigt den Längsschnitt einer beispielswei sen Ausführungsform in verkleinertem Masstab.
Im Rückenpolster 1 eines Motorfahrzeugsitzes 2 ist eine Haltevorrichtung 3 unverrückbar eingebaut, an derem oberen und unteren Ende je ein Zahnrad 4, 5 drehbar befestigt ist.
Die beiden Zahnräder 4, 5 sind mit einer endlo- sen. Kette 6 verbunden. An der dem Rücken zuge- kehrten Seite läuft diese endlose Kette 6 in einer U-Profilschiene 9, die über die beiden Querverbin dungen 8, 8' fest mit der Haltevorrichtung 3 verbun den ist.
Die Rückenstütze 11 ist über eine Feder 10 mit der endlosen Kette 6 derart fest verbunden, dass durch das Hinauf- oder Hemunterdrehen des Zahnra- des 5 diese Rückenstütze innerhalb des Rückenpol sters 1 sich vertikal nach oben oder nach unten ver stellen lässt. Das Zahnrad 5 ist mit einem Drehkopf 7 fest verbunden und zwar derart, dass der jeweils Sitzende den Bewegungsmechanismus ohne weiteres betätigen kann.
Auf diese Art und Weise ist es ohne weiteres möglich, die Rückenstütze 11 so einzustellen, dass die beste Rückenhaltung erreicht wird.
Die sinnvolle, wie einfache Vorrichtung verhin dert in der Folge die Schädigung der Wirbelsäule.
Built-in and adjustable backrest for backrests of motor vehicles It is known that most back cushions of the motorized driver's seats do not correspond to the anatomical conditions of the respective seated person as much as they should.
It is also known that such poor back cushions cause damage to the spine of the engine and passengers in particular, with early signs of fatigue occurring.
The present invention now relates to a built-in and vertically adjustable backrest for backrests of motor vehicles. It is characterized in that the same can be slid up and down in a U-profile rail, which enables every motorist or passenger to adapt the best support position even to the anatomical conditions of his spine in such a way that the above-mentioned damage and signs of fatigue do not occur more can occur.
The adjustable back support can be adjustable by means of a chain drive, a wire pull or a threaded rod.
In the drawing, an example Ausfüh approximately form of the subject invention is shown. Fig. 1 shows the longitudinal section of an exemplary embodiment on a reduced scale.
In the back cushion 1 of a motor vehicle seat 2, a holding device 3 is installed immovably, at the upper and lower ends of which a gear 4, 5 is rotatably attached.
The two gears 4, 5 are endless with one. Chain 6 connected. On the side facing the back, this endless chain 6 runs in a U-profile rail 9 which is firmly connected to the holding device 3 via the two cross connections 8, 8 '.
The back support 11 is firmly connected to the endless chain 6 via a spring 10 in such a way that by turning the toothed wheel 5 up or down, this back support within the back cushion 1 can be adjusted vertically up or down. The gear 5 is firmly connected to a rotating head 7 in such a way that the person sitting in each case can easily operate the movement mechanism.
In this way, it is easily possible to adjust the back support 11 so that the best back posture is achieved.
The sensible and simple device prevents damage to the spine as a result.
