Abstract
Lehne (1) für Kraftfahrzeugsitze mit einem Lehnenholm (1a) und einem mit dem Lehnenholm (1a) verschweißten Oberteil (2a) eines Beschlagteils (2a, 2b), das zur beweglichen Verbindung der Lehne mit der Anschlussfläche (4) eines Sitzrahmens dient, dadurch gekennzeichnet, dass das Oberteil (2a) des Beschlagteils (2a, 2b) innerhalb einer am Lehnenholm (1a) vorgesehenen Vertiefung (1b) mit deren schenkelartigen Seiten verschweißt ist, wobei die Vertiefung (1b) einen Boden aufweist, der im Wesentlichen parallel zur Lehnenholmaußenfläche in Beschlagsnähe ist und der in die schenkelartigen Seiten der Vertiefung, die im Wesentlichen senkrecht zum Boden sind, in Übergangsbereichen übergeht, wobei das Oberteil (2a) des Beschlagteils (2a, 2b) höchstens an den schenkelartigen Seiten und höchstens an einem der in Lehnenlängserstreckung verlaufenden Übergangsbereiche anliegt.Backrest (1) for motor vehicle seats with a backrest spar (1a) and an upper part (2a), welded to the backrest spar (1a), of a fitting part (2a, 2b), which serves to movably connect the backrest to the connection surface (4) of a seat frame, thereby characterized in that the upper part (2a) of the fitting part (2a, 2b) is welded to the leg-like sides of a recess (1b) provided on the backrest spar (1a), the recess (1b) having a bottom which is essentially parallel to the outer surface of the backrest spar is close to the fitting and which merges into the leg-like sides of the recess, which are essentially perpendicular to the floor, in transition areas, the upper part (2a) of the fitting part (2a, 2b) at most on the leg-like sides and at most on one of the sides extending in the longitudinal extension of the backrest Transitional areas.

Aufgabe der Erfindung ist es, die Lehne so auszugestalten, dass die erwähnten Toleranzprobleme nicht mehr auftreten bzw. ihr Auftreten minimiert wird.The object of the invention is to design the back so that the mentioned tolerance problems no longer occur or their occurrence is minimized.
Diese Aufgabe wird durch eine Lehne nach Anspruch 1 bzw. ein Verfahren nach Anspruch 4 gelöst. Weitere vorteilhafte Ausführungsformen finden sich in den Unteransprüchen.This object is achieved by a backrest according to
Erfindungsgemäß ist ein Lehnenholm mit einer bevorzugt U-förmigen Vertiefung vorgesehen, in die der Beschlagteil eingesetzt und mit deren schenkelartigen Seiten er verschweißt ist. Bei dieser Ausgestaltung wird ermöglicht, dass der Lehnenholm beim Verschweißen mit dem Beschlagteil nahezu unverspannt (unverdrillt) verschweißt werden kann, wodurch nach Entnahme des Beschlagteils und des Lehnenholms aus der Schweißvorrichtung eine zu starke Verdrehung des Anschlussbereichs des Beschlagteils um die vertikale Achse wie auch eine Spreizung der Anschlussbereiche vermieden werden können. Weiter kann zwischen dem Boden der Ausnehmung und dem Beschlagteil ein Zwischenraum vorgesehen werden, ohne dass die Schweißnähte bei der Überbrückung des Zwischenraumes zu dick werden.According to the invention, a backrest spar is provided with a preferably U-shaped recess, into which the fitting part is inserted and with the thigh-like sides of which it is welded. In this embodiment, it is possible that the backrest spar when welding with the fitting part almost unstressed (untwisted) can be welded, whereby after removal of the fitting part and the backrest spar from the welding device too strong rotation of the connection portion of the fitting about the vertical axis as well Spreading the connection areas can be avoided. Further, a gap can be provided between the bottom of the recess and the fitting part, without the welds are too thick in the bridging of the gap.
Die Erfindung wird im folgenden anhand der Figuren schematisch näher erläutert:The invention will be explained in more detail below with reference to the figures:
