Abstract

The vehicle is fitted with sensors for the cornering forces as well as the vehicle speed. A simple processor computes correction signals for servo motors which adjust the seat inclination. This tilts the seats into the corner and counteracts the cornering forces. The seat occupants do not need to adjust their sitting position nor to lean into the corner. The tilt control is driven by electric, pneumatic or hydraulic servo motors with the seat mountings on pendant supports. Alternately the whole vehicle can be tilted into the corner by adjusting the suspension. ADVANTAGE - Improved cornering comfort and stability.

Description

Bei der Geradeausfahrt im Kraftfahrzeug kann eine senkrechte Sitzhaltung eingenommen werden. Bei Bild 1 wirkt die Gewichtskraft F (G) auf den Sitz.When driving straight ahead in a motor vehicle, a vertical sitting position can be assumed. In Figure 1, the weight force F (G) acts on the seat.

Bei der Kurvenfahrt tritt zusätzlich die Fliehkraft F (Flieh) auf. Gewichtskraft und Fliehkraft ergeben zusammen die Resultierende R, die schräg gerichtet ist.The centrifugal force F (centrifugal force) also occurs when cornering. Weight and centrifugal force together result in the resultant R, which is oblique is directed.

Bei Bild 2 nimmt der Insasse des KFZ zur Einleitung dieser Resultierenden R durch Neigung des Oberkörpers eine schräge Sitzposition ein, welche unbequem ist und die Fahrsicherheit herabsetzt.In Figure 2, the occupant of the motor vehicle assumes an inclined sitting position to initiate this resultant R by tilting the upper body, which is uncomfortable and reduces driving safety.

Der Erfindung liegt der Gedanke zugrunde, einen automatischen Fliehkraftausgleich zu schaffen, so daß die Insassen nicht mehr selbst die schräge Position einnehmen und sich auch nicht an hierfür angebrachten Haltegriffen festhalten müssen, indem die Sitzflächen automatisch in Schrägstellungen gebracht werden, welche die Resultierende R auffangen und entgegenwirken.The invention is based on the idea of automatic centrifugal force compensation to create so that the occupants no longer take the oblique position themselves and also do not have to hold onto the handles provided for this purpose by the seats are automatically tilted, which the Catch the resulting R and counteract it.

Bild 3 zeigt einen Lösungsvorschlag: der nach links/hochschwenkende Sitz (Drehmittelpunkt z. B. im Schwerpunkt des Oberkörpers) befördert den Körper selbsttätig in die richtige Position zur Aufnahme der Resultierenden R. Der Vorteil wäre ein bequemes, weniger ermüdendes Fahren, besonders in scharfen Kurven und bei höheren Kurvengeschwindigkeiten sowie eine Erhöhung der Fahrsicherheit. Figure 3 shows a proposed solution: the left / swiveling seat (center of rotation e.g. in the center of gravity of the upper body) automatically transports the body into the correct position to accommodate the resulting R. The advantage would be comfortable, less tiring driving, especially in sharp ones Curves and at higher cornering speeds as well as an increase in driving safety.

Die technische Ausführung des automatischen Fliehkraftausgleichs kann auf verschiedene Weisen erreicht werden:The technical execution of the automatic centrifugal force compensation can be achieved in different ways:

In Bild 4 bringt ein Stellmotor den Einzelsitz in die richtige Schrägposition.In Figure 4, a servomotor brings the individual seat into the correct inclined position.

In Bild 5 wird eine ganze Sitzgruppe bewegt.In picture 5 an entire seating group is moved.

In Bild 6 wird dargestellt, wie durch Neigung der ganzen Karosserie der Fliehkraftausgleich erreicht wird. Figure 6 shows how centrifugal force compensation is achieved by tilting the entire body.

Die Verstellvorgänge können mit Hilfe von Stellmotoren/Stellzylindern unter Verwendung von elektrischer, hydraulischer oder pneumatischer Energie ausgeführt werden.The adjustment processes can be done with the help of servomotors / actuating cylinders Using electrical, hydraulic or pneumatic energy will.

Da die Fliehkraft abhängt vom Kurvenradius und der gefahrenen Geschwindigkeit, sollten die Stellglieder gekoppelt werden mit Lenkung/Geschwindigkeitsmesser, ebenso kann die Ansteuerung zur Einstellung des exakt entsprechendes Winkels der Schrägposition der Sitzflächen auch von einem Fliehkraftsensor übernommen werden.Since the centrifugal force depends on the radius of the curve and the speed, should the actuators be coupled with the steering / speedometer, the control for setting the exact corresponding angle can also be used the inclined position of the seats is also taken over by a centrifugal force sensor will.
