Die Aufgabe der vorliegenden Erfindung besteht darin, einen Fahrzeugsitz der eingangs genannten Art mit neuartigen zueinander synchronisierbaren beidseitig angeordneten Antrieben für eine Rückenlehnenneigungsverstellung anzugeben.The The object of the present invention is a vehicle seat of the type mentioned above with novel synchronized with each other arranged on both sides drives for a backrest tilt adjustment specify.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.These The object is solved by the features of claim 1.
Vorteilhafte und zweckmäßige Weiterbildungen der Aufgabenlösung sind in den Unteransprüchen angegeben.advantageous and appropriate further training of the task solution are given in the subclaims.
Die Erfindung schlägt ein Neigungsverstellkonzept für die Rückenlehne vor, bei dem Motoren und Getriebe direkt in die Struktur der Rückenlehne, wahlweise innen oder außen, angeordnet sind. Es sind zwei Antriebe (Motor und Getriebe) vorgesehen, die spiegelbildlich gegenüberliegend angeordnet sind. Zur Synchronisation dieser beiden Antriebe werden diese elektrisch über eine geeignete Schaltung verbunden. Erfindungsgemäß sind die beiden Antriebe Spindelmotoren und werden zur Synchronisation beider Spindelmotoren deren Umdrehungen erfassende Ripple Counter verwendet. Für die genannten Antriebskonzepte sind Gleichstrommotoren vielfältiger Bauart geeignet, bei denen die Ripple Counter Technologie anwendbar ist. Ein Ripple Counter IC wertet ohne den Einsatz von Mechanik und Sensoren die Umdrehungen von Gleichstrommotoren aus. Dazu analysiert der integrierte Schaltkreis (Ripple Counter (IC) typische Daten der Kennlinie des Motorstroms und bestimmt damit Position und Drehzahl des Motors. Die bei einem Gleichstrommotor entstehenden Kommutierungssignale werden als Rückkopplungsinformation genutzt, so dass eine sensorlose und damit kostengünstige Synchronisierung der beiden Antriebe möglich ist. Die Erfindung schlägt somit ein paarig angeordnetes Antriebskonzept für die Rückenlehnenneigungsverstellung vor, welches die Komponenten deutlich kleiner und leichter macht, was bedeutet, dass die Getriebeeinheiten als auch die zu verwendenden Motoren deutlich kleiner bauen können.The Invention proposes a tilt adjustment concept for the backrest in front of the engine and transmission directly into the structure of the backrest, optionally inside or outside, are arranged. There are two drives (engine and transmission) provided, the are arranged mirror-inverted opposite. For synchronization These two drives are electrically powered by a appropriate circuit connected. According to the invention the two drives spindle motors and are for synchronization Both spindle motors whose revolutions detecting ripple counter used. For the drive concepts mentioned DC motors are more diverse Type suitable for which the ripple counter technology applicable is. A ripple counter IC evaluates without the use of mechanics and Sensors detect the revolutions of DC motors. Analyzed the integrated circuit (ripple counter (ic) typical data the characteristic of the motor current and thus determines position and speed of the motor. The resulting in a DC motor commutation be used as feedback information, so that a sensorless and thus cost-effective synchronization of the two drives is possible. The invention thus proposes a pair arranged drive concept for the backrest tilt adjustment which makes the components much smaller and lighter, which means that the gear units as well as the ones to be used Motors can build much smaller.
Der Spindelmotorantrieb kann mit rotierender Spindel oder transversal laufender Spindelmutter ausgebildet sein.Of the Spindle motor drive can be with rotating spindle or transversal be formed running spindle nut.
Alternativ ist eine Lösung mittels Spindelmotor und stehender Spindel und transversal an der Spindel laufendem Getriebe in paralleler Ausführung möglich.alternative is a solution using a spindle motor and a stationary spindle and transverse to the spindle running gear in parallel Execution possible.
Motor und Getriebe können im Winkel zur Spindelwelle angeordnet sein. Alternativ kann auch die Motorwelle parallel zur Spindelwelle angeordnet sein.engine and gear can be arranged at an angle to the spindle shaft be. Alternatively, the motor shaft parallel to the spindle shaft be arranged.
Die Erfindung soll nachfolgend anhand der beigefügten Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, näher erläutert werden.The Invention will be described below with reference to the attached drawing, in which an embodiment is shown, closer be explained.
