Abstract
Description
Die Erfindung betrifft einen Fahrzeugsitz, insbesondere einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Anspruches 1.The The invention relates to a vehicle seat, in particular a motor vehicle seat, with the features of the preamble of claim 1.
Bei längseinstellbaren Fahrzeugsitzen dieser Art ist der Sitzrahmen unmittelbar oder mittelbar über Schwingen auf jeder Fahrzeugsitzseite an je zwei Adaptern an jeder zweiten Sitzschiene angebunden. In der Ausführung als Gurtintegralsitz werden große Kräfte über die Adapter in die Sitzschienen geleitet. Da diese im hinteren Bereich stärker als im vorderen Bereich sind, kann es aufgrund eines entstehenden Drehmomentes, insbesondere in hinteren Längspositionen des Fahrzeugsitzes, im Extremfall zu Verformungen der Sitzschienen bis hin zu einem Ausschälen kommen. Bei einem vereinfacht hergestellten, winkelförmigen Adapter kommt es überlagert zu einer Torsion der zweiten Sitzschiene um eine in Längsrichtung verlaufende Achse, welche auf einer Seite des Sitzschienenprofils die Belastungen besonders erhöht, was im Extremfall zu einem Ausschälen führen kann.at along adjustable Vehicle seats of this type is the seat frame directly or indirectly via swinging on each vehicle seat side to two adapters on each second Seat rail connected. In the execution as Gurtintegralsitz be great Forces over the Adapters led into the seat rails. Since these are in the back area stronger as they are in the front, it may be due to an emerging Torque, especially in rear longitudinal positions of the vehicle seat, In extreme cases, deformations of the seat rails come up to a Ausschälen. In a simplified manufactured, angular adapter it comes to superimposed a torsion of the second seat rail about a longitudinal direction extending axis, which on one side of the seat rail profile especially increases the burdens, which can lead to a peeling in extreme cases.
Der Erfindung liegt die Aufgabe zu Grunde, einen Fahrzeugsitz der eingangs genannten Art zu verbessern, insbesondere seine Crashsicherheit. Diese Aufgabe wird erfindungsgemäß durch einen Fahrzeugsitz mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is based on the object, a vehicle seat of the beginning to improve the type mentioned, in particular its crash safety. These Task is achieved by a vehicle seat with the features of claim 1 solved. advantageous Embodiments are the subject of the dependent claims.
Dadurch, dass der Adapter eine Abstützung aufweist, welche im Crashfall mit der ersten Sitzschiene in Kontakt kommt, kann der Adapter sich außer über die zweite Sitzschiene zusätzlich noch über die erste Sitzschiene abstützen. Mit dieser abstützenden Maßnahme werden die Festigkeitspotentiale der Bauteile besser aus genutzt und ein Ausschälen der Sitzschienen verzögert oder verhindert. Dabei erstreckt sich der Adapter wenigstens näherungsweise über die gesamte Länge der zweiten Sitzschiene, was die Belastungen und die Abstützwirkung über eine größere Länge verteilt. Insbesondere mit einer Anbringung von Elementen eines Sicherheitsgurtsystems im hinteren Bereich des Fahrzeugsitzes ist die Abstützung vorzugsweise im vorderen Bereich des Adapters vorgesehen, um eine kleine Schwenkbewegung des Adapters zu unterstützen.Thereby, that the adapter has a support, which comes into contact with the first seat rail in the event of a crash, can the adapter except beyond the second seat rail additionally still over the support first seat rail. With this supporting measure the strength potentials of the components are better utilized and a peeling of the Seat rails delayed or prevented. In this case, the adapter extends at least approximately over the whole length the second seat rail, what the loads and the supporting action over a greater length distributed. In particular, with an attachment of elements of a safety belt system in the rear region of the vehicle seat, the support is preferably provided in the front of the adapter to a small pivoting movement to support the adapter.
Für geometrisch einfache Verhältnisse ist die Abstützung mit einer nach unten weisenden Auflagefläche versehen, welche im Crashfall in Anlage an die Oberseite der ersten Sitzschiene gelangt. Um den Kontakt und die Anlage zu verbessern, ist die Auflagefläche gezahnt und/oder abgeschrägt und/oder verschränkt.For geometric normal conditions is the support provided with a downwardly facing support surface, which in the event of a crash comes into contact with the top of the first seat rail. To the contact and to improve the system, the support surface is toothed and / or bevelled and / or crossed.
Ein Radius oder andere Übergangskontur am stirnseitigen Ende erleichtert die kleine Schwenkbewegung des Adapters, sofern diese erwünscht ist, und vermeidet eine Beschädigung der ersten Sitzschiene im Crashfall durch ein scharfes Ende des Adapters.One Radius or other transition contour on front end facilitates the small pivoting movement of the adapter, if desired is, and avoids damage the first seat rail in the event of a crash by a sharp end of the Adapter.
Für eine einfache Herstellung weist der Adapter vorzugsweise einen an der Oberseite der zweiten Sitzschiene angebrachten ersten Schenkel und einen aufrechten zweiten Schenkel auf, an welchem der Sitzrahmen unmittelbar oder mittels schwenkbarer Schwingen vorzugsweise an zwei Stellen angebunden ist. Durch diese Ausbildung des Adapters ist der zweite Schenkel außermittig angeordnet. Mit der erfindungsgemäßen Lösung wird ein Tordieren der zweiten Sitzschiene um eine Achse in Längsrichtung verzögert oder verhindert.For a simple Manufacture, the adapter preferably has one at the top the second seat rail mounted first leg and an upright second leg on which the seat frame directly or connected by means of pivoting wings preferably in two places is. By this design of the adapter is the second leg eccentrically arranged. With the solution according to the invention is a twisting of the second Seat rail delayed by an axis in the longitudinal direction or prevented.
