Als Unterpolsterungen dienen regelmäßig Lattenroste. Um eine physiologische Lagerung des ruhenden Körpers zu erreichen, soll das Bettsystem mit der Unterpolsterung eine hinreichende Absenkung im Schulter- und im Beckenbereich zulassen, so dass die Wirbelsäule in Rückenlage und auch in Seitenlage im wesentlichen gestreckt liegt. Dazu sind in den Gestellen von Sitz- oder Liegemöbel, insbesondere in den als Gestell anzusehenden Lattenrosten von Betten zwischen deren Längsholmen querliegend angeordnete Latten vorgesehen, die die Polsterauflage aufnehmen, und die als Federlatten ausgebildet sind. Die Lattenköpfe sind beidseitig mit Endstücken versehen, die das Festlegen an dem Gestell bzw. an den Längsholmen erlauben, die - zur Verbesserung des Liegekomforts - auch unterteilt und mit Gelenken aneinander gelenkt sein können, um das Kopfteil oder das Fußteil aufstellen zu können.Seating or reclining furniture, especially beds, have upholstered surfaces on, which are formed by cushion pads (mattresses or the like.) in turn are placed on a padding. As padding regularly serve slatted frames. To be a physiological To reach the resting body, the bed system is supposed to the padding a sufficient lowering in the shoulder and in Allow pelvic area so that the spine is supine and also lies stretched in the lateral position. These are in the frames of seating or reclining furniture, especially in the as Frame slatted frames of beds between their longitudinal spars transversely arranged slats provided that the upholstery record, and which are designed as spring slats. The Slatted heads are provided on both sides with end pieces that fix them allow on the frame or on the longitudinal spars, which - to Improvement of lying comfort - also divided and with joints can be directed to one another around the head part or the foot part to be able to set up.

Zur weiteren Verbesserung des Liegekomforts ist aus EP 0 401 712 und EP 0 653 174 bekannt, die Sitz- oder Liegefläche nicht nur durch Federlatten in Längsrichtung zu unterteilen, sondern auch durch Federelemente in Querrichtung, so dass eine in Einzelflächen aufgelöste Liegefläche entsteht. Bei derartigen Polstersystemen ist wegen der speziellen Ausbildung der Federung der Einsatz (relativ) dünner und somit auch leichter Polsterauflagen ohne Komfortverlust möglich. Dazu werden nach EP 0 401 712 Starrlatten eingesetzt, die als U-Profile mit hochstehenden Flanschen die Federelemente aufnehmen und deren Hub begrenzen.To further improve lying comfort, EP 0 401 712 and EP 0 653 174, not only the sitting or lying surface to divide by spring slats in the longitudinal direction, but also by spring elements in the transverse direction, so that one in individual areas dissolved lying surface is created. With such upholstery systems due to the special design of the suspension the use (relative) thinner and therefore lighter upholstery pads without loss of comfort possible. According to EP 0 401 712 rigid slats are used take up the spring elements as U-profiles with upstanding flanges and limit their stroke.

Aus dem deutschen Gebrauchsmuster 297 21 656.2 ist zur Bildung einer Polsterfläche eine Federlatte bekannt geworden, von der eine Anzahl parallel zueinander verlaufend in dem Gestell eines Sitzoder Liegemöbels, insbesondere zwischen den zwei Längsholmen eines Lattenrahmens eines Bettes über die Länge verteilt, angeordnet sind. Auf diesen Federlatten sind eine Anzahl von Federelementen in Spalten und Reihen angeordnet, so dass ein im wesentlichen regelmäßiges Muster gebildet ist. Diese Federlatte ist eine Kunststoffleiste von im wesentlichen U-förmigen Querschnitt, deren Lattenköpfe als Endstücke ausgebildet, das Festlegen an dem Gestell des Sitz- bzw. Liegemöbels bzw. an den Längsholmen eines Lattentrostes für Betten erlauben.From the German utility model 297 21 656.2 is to form a Upholstered surface of a spring slat became known, one of which Number running parallel to each other in the frame of a seat or Lying furniture, especially between the two longitudinal spars one Slatted frame of a bed distributed over the length, arranged are. On these spring slats are a number of spring elements in Columns and rows arranged so that an essentially regular Pattern is formed. This spring slat is a plastic strip of essentially U-shaped cross-section, whose slatted heads formed as end pieces, the fixing on the frame of the Seating or reclining furniture or on the longitudinal spars of a slatted frame allow for beds.

Nachteilig ist hier, dass die Herstellung derartiger Federlatten kostenintensiv und die Montage solcher Lattenroste äußerst arbeitsintensiv ist, so dass eine wirtschaftliche Fertigung nicht ohne weiteres erreicht werden kann.The disadvantage here is that the manufacture of such spring slats costly and the assembly of such slatted frames extremely labor intensive is, so economic production is not without more can be achieved.

Darauf folgt die dieser Erfindung zugrunde liegende Aufgabenstellung, die bekannten Federlatten derart weiter zu bilden, dass Herstellung und Montage vereinfacht und so wirtschaftlicher werden.This is followed by the problem underlying this invention, to further develop the known spring slats in such a way that manufacture and assembly simplified and thus more economical.

Die Aufgabenlösung ist durch die kennzeichnenden Merkmale des Hauptanspruchs gegeben; vorteilhafte Weiterbildungen und bevorzugte Ausführungsformen beschreiben die Unteransprüche.The task solution is due to the characteristic features of the main claim given; advantageous developments and preferred embodiments describe the subclaims.

Bei den Federlatten nach der Erfindung ist der Lattenkörper gebildet von zumindest zwei im Abstand voneinander angeordneten U-Profilen, die nach unten geöffnet sind. Diese U-Profile sind längs ihrer Längserstreckung durch im Abstand voneinander angeordneten Stege sowie an ihren Lattenköpfen durch Endstücke verbunden, die derart ausgebildet sind, dass eine direkte Befestigung an dem Gestell bzw. an den Längsholmen möglich ist. Diese Federleisten, die ihrerseits im Abstand voneinander angeordnet werden, bilden die Basis einer Polsterfläche, auf die Federelemente aufgesetzt werden, wobei eine von den Federelementen getragene Polsterschicht die Polsterfläche ergänzt. Dabei geben die Auflage- bzw. Kopfplatten solcher Federelemente die Geometrie der Anordnung der Befestigungsmittel und somit auch der Federlatten vor. Dadurch können die Federlatten in gewünschten Abständen und parallel zueinander so angeordnet werden, dass die Federelemente ein im wesentliches regelmäßiges Muster bilden, das die Polsterlage als Auflagepolster aufnimmt.In the spring slats according to the invention, the slat body is formed of at least two spaced U-profiles, which are open at the bottom. These U-profiles are along their length by spaced apart webs as well as their slatted heads connected by end pieces formed in this way are that a direct attachment to the frame or to the longitudinal spars is possible. These female connectors, which in turn are at a distance arranged from each other, form the basis of a cushion surface, are placed on the spring elements, one of the spring elements worn upholstery layer complements the upholstery surface. Give in doing so the support or head plates of such spring elements have the geometry the arrangement of the fasteners and thus also the spring slats in front. This allows the spring slats at the desired intervals and in parallel to be arranged so that the spring elements in a form an essential regular pattern that the cushion layer as a pad receives.

Um die Federlatten zu versteifen, ist es vorteilhaft, wenn die Höhe des U-Profils in dessen Mitte gegenüber den beiden an dem Längsholm festliegenden Lattenenden größer ist. Diese Mitten-Überhöhung liegt dabei zwischen 1/3-tel bis 2/3-tel der Höhe des U-Profils am Rand. Weiter wird an den freien Enden der Schenkel des U eine Wulst vorgesehen, die nach außen etwa um eine Dicke des Materials des Schenkels übersteht.To stiffen the spring slats, it is advantageous if the height of the U-profile in the middle opposite the two on the longitudinal spar fixed slat ends is larger. This mid-rise lies thereby between 1 / 3rd to 2/3 of the height of the U-profile at the edge. Furthermore, a bead is provided at the free ends of the legs of the U, the outside about a thickness of the material of the leg survives.

Vorteilhaft sind die U-Profile paarweise durch die Stege miteinander verbunden, die in Bezug auf die Längsersteckung der Federlatte quer dazu ausgerichtet sind. Die Stege sind mit Befestigungsmitteln für Federelemente versehen. Vorteilhaft bilden diese Stege mit einer Stegplatte und mit Querwänden eine quer zur Längserstreckung des Lattenkörpers der Federlatte ausgerichtete U-Form. Auf diese Befestigungsmittel werden die Federelemente aufgesetzt. Um die Bauhöhe niedrig halten zu können, sind nach einer vorteilhaften Weiterbildung Stegplatten der Stege napfartig vertieft ausgebildet. Der Fuß der Federelemente kann somit in der napfartigen Vertiefung versenkt untergebracht werden.The U-profiles are advantageous in pairs through the webs connected, the transverse in relation to the longitudinal extension of the spring slat are aligned. The webs are with fasteners for Provide spring elements. These webs advantageously form with a Web plate and with transverse walls one transverse to the longitudinal extension of the slat body the U-shape aligned with the spring slat. On these fasteners the spring elements are put on. Low in height to be able to hold are after an advantageous further training Web plates of the webs are recessed in a cup-like manner. The foot of the spring elements can thus be sunk in the cup-like recess become.

Als Befestigungsmittel für die Federelemente ist bei einer Ausführungsform ein Loch vorgesehen, in das ein an den Fuß jedes der Federelemente angeformter Zapfen eingreift, wodurch das Federelement an der Federlatte festgelegt ist. Bei einer anderen Ausführungsform ist (in aus DE 299 16 753.4 bekannter Weise) als Befestigungsmittel eine T-förmige Anformung vorgesehen, die mit einer langlochähnlich ausgebildeten Öffnung zusammenwirkt und so ein Festlegen des Federelements an der Federlatte ermöglicht. Dabei ist es ohne Bedeutung, ob die Stegplatte oder der Federelement-Fuß mit der T-förmigen Anformung versehen ist und der Federelement-Fuß oder die Stegplatte die langlochähnlich ausgebildete Öffnung aufweisen oder umgekehrt. Zur Vereinfachung der Montage kann die T-förmige Anformung als auf die Stegplatte aufsetzbarer Aufsatz ausgebildet sein.In one embodiment, the fastening means for the spring elements a hole is provided in the one at the foot of each of the spring elements molded pin engages, causing the spring element the spring batten is fixed. In another embodiment (in a manner known from DE 299 16 753.4) as a fastening means T-shaped formation provided with a slot-like design Opening interacts and so a fixing of the spring element enabled on the spring slat. It does not matter whether the Web plate or the spring element foot with the T-shaped projection is provided and the spring element foot or the web plate which is similar to an elongated hole have a trained opening or vice versa. For simplification The T-shaped projection can be mounted on the multi-wall sheet attachable essay be formed.

Zum Festlegen der Federlatte an dem Gestell des Sitz- oder Liegemöbels bzw. an dem Lattenrost sind die die beiden U-Profile verbindenden Endstücke vorteilhaft plattenförmig ausgebildet und liegen am Gestell bzw. an den Längsholmen des Lattenrost-Rahmens an. So können diese Endplatten in einfacher Weise befestigt werden, ohne dass es etwa einer Vorbohrung für Dübel bedarf. Das Befestigen erfolgt zweckmäßig mit Stiften, Schrauben, ggf. durch Anschießen, was jedoch auch eine Dübelbefestigung nicht ausschließt. Vorteilhaft werden die Endstücke so ausgebildet, dass eine rechtwinklig abstehende Lasche angesetzt oder angeformt ist, mit der die Federlatte an dem Gestell des Sitz- oder Liegemöbels bzw. den Längsholmen des Lattenrostes abstützbar ist. So können die auf die Befestigungsmittel wirkenden Scherkräfte abgefangen oder - wenn die angesetzte oder angeformte Lasche das Gestell bzw. den Längsholm übergreift bzw. in den Längsholm eingreift - sogar aufgehoben werden und in das Gestell des Sitz- oder Liegemöbels bzw. in den Rahmen des Lattenrostes eingeleitet werden.For fixing the spring slat to the frame of the seating or reclining furniture or on the slatted frame are the connecting the two U-profiles End pieces are advantageously plate-shaped and lie on the frame or on the longitudinal spars of the slatted frame. So can these end plates can be easily attached without it about a pre-hole for dowels. The attachment is convenient with pins, screws, if necessary by shooting, but also a dowel attachment does not rule out. The end pieces are advantageous designed so that a tab protruding at right angles is attached or is molded, with which the spring slat on the frame of Seat or reclining furniture or the longitudinal bars of the slatted frame can be supported is. So can the shear forces acting on the fasteners intercepted or - if the attached or molded tab engages over the frame or the longitudinal spar or engages in the longitudinal spar - Even be lifted and in the frame of the seat or Lying furniture or into the frame of the slatted frame.

Zur Erhöhung der Stabilität ist der Federkörper 1 symmetrisch zur Mitte hin nach oben durchgebogen. Dadurch ist die Höhe "H" der U-Profile in der Mitte etwa 4/3-tel bis 5/3-tel der Höhe "h" der U-Profile am Rand (Fig. 3). Vorteilhaft sind an die unteren Außenkanten beider U-Profile Verstärkungswülste 3.1 bzw. 4.1 angeformt. Diese Verstärkungswülste 3.1 bzw. 4.1 stehen etwa rechtwinklig zu den Schenkeln der U-Profile 3 bzw. 4 ab, wobei ihre Tiefe mindestens gleich der Materialstärke der Schenkel der U-Profile 3 bzw. 4 ist. Beide U-Profile sind über Zwischenstege 5 miteinander verbunden, die über die Länge der U-Profile in regelmäßigen Abständen voneinander verteilt sind. Diese Zwischenstege 5 sind dabei mit den zwischen den U-Profilen 3 und 4 verlaufenden Stegplatten 6 und den Querwänden 7 als querliegende U-Formen ausgebildet.The figures show the spring slat with the slat body 1. This becomes formed by the U-profiles 3 and 4. These U profiles 3 and 4 run parallel to each other, they are open at the bottom. To increase the stability of the spring body 1 is symmetrical towards the center bent at the top. This means that the height "H" of the U-profiles is in the middle about 4 / 3rd to 5 / 3rd of the height "h" of the U-profiles at the edge (Fig. 3). Are advantageous on the lower outer edges of both U-profiles Reinforcing beads 3.1 or 4.1 molded. These reinforcing beads 3.1 and 4.1 are approximately at right angles to the legs of the U-profiles 3 or 4, their depth being at least equal to the material thickness the leg of the U-profiles is 3 or 4. Both U profiles are over Intermediate webs 5 connected to each other over the length of the U-profiles are distributed at regular intervals. This Intermediate webs 5 are with the between the U-profiles 3 and 4 extending web plates 6 and the transverse walls 7 as transverse U-shapes educated.
