Abstract

The invention relates to a mattress with a mattress body (1) composed of foam, which has zones (A to G) of varying hardness. To create a simpler and thus less expensive mattress, it is proposed according to the invention that the zones (A to G) of varying hardness are formed by shaped bodies (2a, 2b, 2c, 2d) formed into the mattress body (1). <IMAGE>

Description

Die Erfindung betrifft eine Matratze mit einem aus Schaumstoff bestehenden Matratzenkörper, der Zonen unterschiedlicher Härte aufweist.The invention relates to a mattress with a mattress body made of foam, which has zones of different hardness.

Durch die DE-OS 34 24 942 ist eine Matratze bekanntgeworden, deren Kern aus einem Sandwich-Schaumstoffkörper besteht, dessen obere und untere Lage mit der Mittellage verklebt sind. Dabei besteht die Mittellage aus zahlreichen, jeweils stumpf aneinander anliegenden und sich jeweils über die volle Matratzenbreite erstreckenden Zellsegmenten unterschiedlicher Härte. Jedes Zellsegment weist an seiner dem benachbarten Zellsegment zugewandten Längsseite eine zur Längsseite hin offene Ausfräsung auf, die mit der Ausfräsung des benachbarten Zellsegmentes eine Luftkammer bildet. Die obere und untere Lage weisen jeweils lotrecht zur Matratzenebene verlaufende Luftkanäle auf, in deren Bereich die Klebschichten zwischen den drei Lagen unterbrochen sind. Dabei bestehen die obere und untere Lage jeweils aus Stiftlatex, während die Zellsegmente aus Schaumstoff bestehen.From DE-OS 34 24 942 a mattress has become known, the core of which consists of a sandwich foam body, the upper and lower layers of which are glued to the middle layer. The middle layer consists of numerous cell segments of different hardness, each abutting one another and each extending across the full mattress width. Each cell segment has on its long side facing the adjacent cell segment a cutout which is open towards the long side and which forms an air chamber with the cutout of the adjacent cell segment. The upper and lower layers each have air ducts running perpendicular to the mattress level, in the area of which the adhesive layers between the three layers are interrupted. The upper and lower layers are made of pencil latex, while the cell segments are made of foam.

Bei dieser vorbekannten Matratze sind sieben Zonen unterschiedlicher Härte vorgesehen, nämlich eine Kopf-, eine Nacken-, eine Schulter-, eine Lenden-, eine Hüft-, eine Oberschenkel- und eine Unterschenkelzone. Dabei weisen die Nacken-und Lendenzone die jeweils größte Härte, Kopf- sowie Unterschenkelzone hingegen die jeweils geringste Härte auf. Schulter- und Oberschenkelzone können die gleiche Härte aufweisen.In this previously known mattress, seven zones of different hardness are provided, namely a head, a neck, a shoulder, a lumbar, a hip, a thigh and a lower leg zone. The neck and lumbar zones each have the greatest hardness, while the head and lower leg zones each have the lowest hardness. The shoulder and thigh zones can have the same hardness.

Bei dieser vorbekannten Matratze ist die Kopfzone zumindest doppelt so breit ausgebildet wie die Nackenzone, aber zumindest halb so breit wie die Unterschenkelzone. Hüft- und Oberschenkelzone sind etwa gleich breit ausgebildet. Die Nackenzone bildet die schmalste und die Unterschenkelzone die breiteste Zone.In this known mattress, the head zone is at least twice as wide as the neck zone, but at least half as wide as the lower leg zone. The hip and thigh zones are approximately the same width. The neck zone is the narrowest and the lower leg zone is the widest.

Der Erfindung liegt die Aufgabe zugrunde, eine in der Herstellung einfachere und damit kostengünstigere Matratze mit vergleichbaren Eigenschaften zu schaffen.The invention has for its object to provide a mattress that is simpler to manufacture and therefore less expensive and has comparable properties.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Zonen unterschiedlicher Härte durch in den Matratzenkörper eingeschäumte Formkörper gebildet sind.This object is achieved according to the invention in that the zones of different hardness are formed by molded bodies foamed into the mattress body.

Dabei ist es vorteilhaft, wenn die Formkörper von dem Schaumstoff des Matratzenkörpers allseitig umschlossen sind.It is advantageous if the molded bodies are enclosed on all sides by the foam of the mattress body.

Unter "Schaumstoff" des Matratzenkörpers soll auch Latex oder eine Kombination beider Materialien verstanden werden. Die Formkörper können auch aus einem Schaumstoff bestehen, dessen Härte größer ist als die des den Matratzenkörper bildenden Schaumstoffs."Foam" of the mattress body should also be understood to mean latex or a combination of both materials. The moldings can also consist of a foam whose hardness is greater than that of the foam forming the mattress body.

Mit dem erfindungsgemäßen Prinzip lassen sich grundsätzlich zwei unterschiedliche Matratzentypen herstellen:
Die unterschiedlichen Kernfestigkeiten bzw. -härten können durch Einschäumung von Formkörpern erzielt werden, die aus jeweils gleichem Material bestehen und somit untereinander auch gleiche Härte aufweisen, die größer ist als die Härte des den Matratzenkörper bildenden Schaumstoffs.In principle, two different types of mattresses can be produced with the principle according to the invention:
The different core strengths or hardnesses can be achieved by foaming in moldings which consist of the same material and thus have the same hardness, which is greater than the hardness of the foam forming the mattress body.

Der zweite Matratzentyp wird dadurch gebildet, daß in den eine mittlere Härte aufweisenden Matratzenkörper Formkörper unterschiedlicher Härte eingeschäumt werden. Hierdurch läßt sich z. B. eine Matratze mit sieben Zonen unterschiedlicher Härte bilden, wobei die Nackenzone sowie die Hüftzone Formkörper höherer Härte und die Oberschenkelzone einen Formkörper geringerer Härte aufweisen.The second type of mattress is formed by foaming moldings of different hardness into the mattress body which has an average hardness. This allows z. B. form a mattress with seven zones of different hardness, wherein the neck zone and the hip zone have molded articles of higher hardness and the thigh zone have a molded article of lower hardness.

Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche und werden in Verbindung mit weiteren Vorteilen der Erfindung anhand von Ausführungsbeispielen näher erläutert.Further features of the invention are the subject of the dependent claims and are explained in more detail in connection with further advantages of the invention on the basis of exemplary embodiments.

Figure 2 -
a modified embodiment in a representation according to Figure 1 .

Bei dem Ausführungsbeispiel gemäß Figur 1 sind in den aus einem Schaumstoff bestehenden Matratzenkörper 1 zur Bildung von Zonen unterschiedlicher Härte Formkörper 2a, 2b und 2c eingeschäumt, die aus gleichem Material, z. B. dem gleichen Schaumstoff bestehen, also gleiche Härte bzw. Festigkeit, in dem dargestellten Ausführungsbeispiel jedoch unterschiedliche Breite aufweisen.In the embodiment according to FIG. 1, molded bodies 2a, 2b and 2c are foamed into the mattress body 1 made of a foam to form zones of different hardness, which are made of the same material, for. B. consist of the same foam, ie the same hardness or strength, but have different widths in the illustrated embodiment.

Bei dem Ausführungsbeispiel gemäß Figur 2 handelt es sich um eine Matratze mit sieben Zonen unterschiedlicher Härte; vorgesehen sind eine Kopfzone A, eine Nackenzone B, eine Schulterzone C, eine Hüftzone D, eine Beckenzone E, eine Oberschenkelzone F sowie eine Unterschenkelzone G. Während der den Matratzenkörper 1 bildende Schaumstoff eine mittlere Härte aufweist, sind in der Nackenzone B und der Hüftzone D Formkörper 2d höherer Härte eingeschäumt, während in die Oberschenkelzone F ein Formkörper 2c mit einer Härte eingeschäumt ist, die unter der des Matratzenkörpers 1 liegt.The embodiment according to FIG. 2 is a mattress with seven zones of different hardness; A head zone A, a neck zone B, a shoulder zone C, a hip zone D, a pelvic zone E, a thigh zone F and a lower leg zone G are provided. While the foam forming the mattress body 1 has a medium hardness, there are B and the hip zone in the neck zone D molded body 2d of higher hardness is foamed, while in the thigh zone F a molded body 2c is foamed with a hardness that is lower than that of the mattress body 1.
