Abstract

The adjustable device comprises connecting elements, which are rotatable to each other at the connection points and produce an adjustable connection in the longitudinal direction between the seat (1) or the seat backrest and a component (3) fixed to the vehicle chassis, such that twisting or torsion of the seat or seat backrest is reduced and the adjustability of the seat remains in longitudinal direction. The free movement of the seat or seat backrest is reduced in the transverse and longitudinal directions, where reduction of the movement is carried out by a mechanical or automatic locking.

Description

Die Erfindung bezieht sich auf in Kraftfahrzeugen verwendete Sport- oder Schalensitze, die längs verstellbar sind und in Verbindung mit 4-(oder mehr)Punkt-Sicherheitsgurten verwendet werden.The invention relates to sports or bucket seats used in motor vehicles, which are longitudinally adjustable and used in conjunction with 4- (or more) point safety belts.

Stand der TechnikState of the art

In Kraftfahrzeugen werden besonders zu Sport- oder Rennsportzwecken so genannte Sport- oder Schalensitze verwendet. Diese Sitze können in Verbindung mit 4-(oder mehr)Punkt-Sicherheitsgurten verwendet werden und erlauben dem Fahrer/Beifahrer den Einsatz eines HANS(Head and Neck Support)-Systems zum Schutz der Wirbelsäule bei Unfällen. Wird ein solches HANS-System genutzt, besteht die Gefahr, dass es bei einem Unfall durch eine ungewollte Verwindung/Verdrehung des Sitzes bzw. der Sitzlehne bei der nach dem Aufprall auftretenden Rückwärtsbewegung des Fahrers/Beifahrers zu einer Kollision eines Teiles des Sitzes bzw. der Sitzlehne mit einem Teil des HANS-Systems kommt. Erhebliche bis tödliche Verletzungen des Fahrers/Beifahrers im Bereich der Wirbelsäule können die Folge sein.In motor vehicles, so-called sports or bucket seats are used especially for sports or racing purposes. These seats can be used in conjunction with 4- (or more) point safety belts and allow the driver / passenger to use a HANS (Head and Neck Support) system to protect the spine in the event of an accident. If such a HANS system is used, there is a risk that in an accident by accidental twisting / twisting of the seat or the seat back in the occurring after the impact of the rearward movement of the driver / passenger to a collision of a part of the seat or the Seat back comes with a part of the HANS system. Significant or fatal injuries to the driver / passenger in the area of the spine can be the result.

Während in Fahrzeugen mit feststehenden (nicht längs verstellbaren) Sitzen eine einfache zusätzliche Befestigung im Bereich der Rückenlehne des Sitzes mit dem Fahrzeugchassis oder daran befestigten Bauteilen die Verwindung/Verdrehung des Sitzes reduzieren kann, muss in Fahrzeugen mit in Längsrichtung verstellbaren Sitzen eine Vorrichtung zum Einsatz kommen, welche es ermöglicht, diese Verbindung entsprechend der Positionsänderung des Sitzes bzw. der Sitzlehne anzupassen.While in vehicles with fixed (not longitudinally adjustable) seats a simple additional attachment in the region of the backrest of the seat with the vehicle chassis or components attached to it can reduce the twist / twist of the seat, a device must be used in vehicles with longitudinally adjustable seats , which makes it possible to adapt this compound according to the change in position of the seat or the seat back.

Aufgabenstellungtask

Gegenstand der vorliegenden Erfindung ist eine Vorrichtung zur Reduzierung der Bewegungsfreiheit des Sitzes bzw. der Sitzlehne in Kraftfahrzeugen in Längs- und/oder Querrichtung und/oder Verwindung/Verdrehung des Sitzoberteiles bei gleichzeitigem Erhalt der Möglichkeit zur Einstellung des Sitzes in Längsrichtung.The present invention is a device for reducing the freedom of movement of the seat or the seat back in motor vehicles in the longitudinal and / or transverse direction and / or twisting / twisting of the seat shell while maintaining the ability to adjust the seat in the longitudinal direction.

Diese Vorrichtung reduziert bei einem Aufprall des Fahrzeuges auf ein Hindernis die aus den Beschleunigungskräften hervorgerufene Bewegung des Sitzes bzw. der Sitzlehne und verringert das Risiko einer wie oben beschriebenen Verletzungsgefahr für den Fahrer/Beifahrer.This device reduces the movement of the seat or the seat back caused by the acceleration forces in the case of a collision of the vehicle with an obstacle and reduces the risk of a driver / passenger injury as described above.

Ausführungsbeispielembodiment

Im Folgenden wird die Erfindung anhand von Beispielen und mit Bezug auf die beiliegenden Zeichnungen erläutert, wobeiIn the following, the invention will be explained by way of example and with reference to the accompanying drawings, wherein

in Seiten- und Rückansicht eine erfindungsgemäße Versteifungsvorrichtung zeigt, welche die Bewegung des Sitzes in Querrichtung und Verwindung/Verdrehung reduziert und in side and rear view shows a stiffening device according to the invention, which reduces the movement of the seat in the transverse direction and twist / twist and

in Seiten- und Rückansicht eine erfindungsgemäße Versteifungsvorrichtung zeigt, welche die Bewegung des Sitzes in Längsrichtung und Verwindung/Verdrehung reduziert. in side and rear view shows a stiffening device according to the invention, which reduces the movement of the seat in the longitudinal direction and twisting / twisting.

In ist eine Versteifungsvorrichtung gezeigt, welche über zwei zueinander (5) und an den Anbindungspunkten drehbare (2, 7) Verbindungselemente (4, 6) eine in Längsrichtung verstellbare Verbindung zwischen dem Sitz (1) bzw. der Sitzlehne und einem am Fahrzeugchassis befestigten Bauteiles (3), hier beispielhaft Rohr des Überrollkäfigs, herstellt und so die Bewegung in Querrichtung und Verwindung/Verdrehung des Sitzes bzw. der Sitzlehne reduziert.In a stiffening device is shown, which over two mutually ( 5 ) and rotatable at the connection points ( 2 . 7 ) Connecting elements ( 4 . 6 ) a longitudinally adjustable connection between the seat ( 1 ) or the seat back and a component attached to the vehicle chassis ( 3 ), here exemplified tube of the roll cage, manufactures and thus reduces the movement in the transverse direction and torsion / twisting of the seat or the seat back.

In ist eine Versteifungsvorrichtung gezeigt, welche über zwei am Fahrzeugchassis befestigte Gurte (2) eine in Längsrichtung verstellbare Verbindung zwischen dem Sitz (1) bzw. der Sitzlehne und dem Fahrzeugchassis herstellt und so die Bewegung in Längsrichtung und Verwindung/Verdrehung des Sitzes bzw. der Sitzlehne reduziert. Die Befestigung der Gurte am Fahrzeugchassis ist hier beispielhaft durch einen automatischen Aufrollmechanismus (4) dargestellt.In a stiffening device is shown, which via two fastened to the vehicle chassis straps ( 2 ) a longitudinally adjustable connection between the seat ( 1 ) or the seat back and the vehicle chassis and thus reduces the movement in the longitudinal direction and twisting / twisting of the seat or the seat back. The attachment of the straps on the vehicle chassis is here by way of example by an automatic retracting mechanism ( 4 ).
