FIELD OF THE INVENTION

This invention relates to a mattress.

BACKGROUND OF THE INVENTION

A mattress is known from WO 2015/64222 A1, having a casing and a foam body that is accommodated in the casing. The foam body has a first and a second horizontal foam layer situated one on top of the other, the first horizontal foam layer being made of latex or a latex-like foam, and the second foam layer being made of a shape memory foam.
Such a mattress provides a high level of lying comfort, and is suited for various sleeping habits.
The object of the invention is to further increase the comfort of such a mattress.
This object is achieved by the invention set forth in claim 1.
According to the invention, the comfort of the mattress is further increased by providing the mattress with the functionality of a support apparatus that is adjustable by electric motor, for example and in particular, a slatted frame that is adjustable by electric motor.
Within this meaning, the invention provides a support apparatus, which is adjustable by electric motor, having a base body with at least two support parts which are adjustable relative to one another and bear spring elements, and at least one electric motor-driven adjustment apparatus which is situated on the support apparatus for adjusting the support parts relative to one another, and which has at least one electric motor that is in operative connection with the support parts in order to adjust same. According to the invention, a recess is formed in the foam body, and is dimensioned in such a way that the support apparatus together with the adjustment apparatus is accommodatable in the recess, the support apparatus together with the adjustment apparatus being accommodated in the recess. An electrical line arrangement that has power supply lines for supplying power, and/or control lines for controlling the adjustment apparatus is led out of the casing of the mattress through an opening in the casing.
In this way the mattress is adjustable by electric motor, thus increasing the functionality and the comfort. The support apparatus that is adjustable by electric motor together with the adjustment apparatus may already be introduced into the mattress casing during manufacture of the mattress. However, according to the invention it is possible to retrofit an existing mattress.
In contrast to the approach known from EP 1 239 753 B1, in which a mattress together with a slatted frame that is adjustable by electric motor is accommodated in a shared casing, according to the invention the support apparatus that is adjustable by electric motor is accommodated in the casing of the mattress itself. A separate casing is thus unnecessary.
The invention thus provides, in a surprisingly simple manner, a mattress which has improved functionality and increased comfort, and which at the same time is easily and economically manufacturable.
According to the invention, the foam body of the mattress may have a single foam layer that forms the cushioning of the mattress. However, one advantageous further embodiment of the invention provides that the foam body has multiple horizontal foam layers in succession in the vertical direction. In this way, the cushioning and suspension properties of the mattress are adjustable within wide limits. In this embodiment the foam layers may be joined together, for example foamed onto one another. However, it is also possible for the foam layers to be formed by separate foam elements that are accommodated inside the casing of the mattress and are combined and held together by same.
Another further embodiment of the invention provides that the recess is formed in the foam body at the top in the vertical direction in such a way that the support apparatus is situated on the top side of the foam body. In this embodiment, the mattress has layering made up of the support apparatus on top and foam element(s) on the bottom. It has surprisingly been shown that, even when the support apparatus is situated above the foam body, i.e., resting directly beneath the casing of the mattress, this does not result in appreciable loss of comfort for a user of the mattress, in particular when the support apparatus is covered by a cover layer, which may have a relatively thin design, situated on the support apparatus.
According to the invention, it is also possible for the support apparatus to be situated between two foam layers in the vertical direction. In this embodiment the support apparatus may be accommodated, for example, between two foam layers in a sandwich-like manner.
The casing of the mattress may, for example and in particular, be made of a textile material.
One advantageous further embodiment of the invention provides that the opening in the casing is closable by means of a zipper. In this way the electrical line arrangement may be led out of the casing is a particularly simple manner. In principle, however, it is also possible to lead the line arrangement out through a separate opening in the casing.
Another extremely advantageous further embodiment of the invention provides that a control apparatus for controlling the adjustment apparatus is situated on the support apparatus within the casing, and is in data transmission connection with a hand control apparatus wirelessly, in particular via radio. In this embodiment, it is only necessary for power supply lines for supplying power to the electric motor-driven adjustment apparatus to be led out of the casing. Since control lines are superfluous due to wireless operation of the control apparatus by means of a hand control apparatus, it is not necessary to lead such control lines out of the casing of the mattress.
According to the invention, it is possible in principle to provide the electric motor-driven adjustment apparatus loosely on the support apparatus. However, one advantageous further embodiment of the invention provides that the support apparatus is connected to the electric motor-driven adjustment apparatus to form a unit. This simplifies installation of the support apparatus together with the adjustment apparatus on the mattress or in the casing of the mattress.
The support apparatus may have any given design in order to carry out the desired support and suspension functions. One advantageous further embodiment of the invention provides that the support apparatus is designed as a slatted frame.
A method according to the invention for equipping or retrofitting a mattress with a support apparatus that is adjustable by electric motor is set forth in claim 9.
The method according to the invention proceeds from a mattress having a closable casing and a foam body that is accommodated in the casing. Within the scope of the method according to the invention, the casing is opened, which may take place, for example and in particular, via a zipper provided on the casing. In the method according to the invention, a support apparatus that is adjustable by electric motor is used, the support apparatus having a base body with at least two support parts which are adjustable relative to one another and bear spring elements, at least one electric motor-driven adjustment apparatus for adjusting the support parts relative to one another being situated on the support apparatus, and having at least one electric motor that is in operative connection with the support parts in order to adjust same.
In the method according to the invention, the support apparatus together with the adjustment apparatus situated thereon is inserted into a recess that is formed in the foam body, wherein an electrical line arrangement that has power supply lines for supplying power, and/or control lines for controlling the adjustment apparatus, is led out through a recess that is formed in the casing, and the casing is once again closed.
The method according to the invention allows a mattress to be equipped or retrofitted with a support apparatus that is adjustable by electric motor, in a simple and economical manner in order to increase the comfort and the functionality of the mattress.
This correspondingly results in the same advantages as for a mattress according to the invention.
One further embodiment of the method according to the invention provides that the support apparatus together with the electric motor-driven adjustment apparatus is inserted into a recess that is formed on the foam body at the top in the vertical direction in such a way that the support apparatus is situated on the top side of the foam body.
Another further embodiment of the method according to the invention provides that the foam body has at least two horizontal foam layers in succession in the vertical direction, and wherein the support apparatus together with the electric motor-driven adjustment apparatus is inserted between two foam layers of the foam body. In this embodiment, the support apparatus is accommodated between two foam layers in a sandwich-like manner.
According to the invention, the foam body may already be formed during manufacture of the mattress, for example by providing a corresponding recess in such a way that the support apparatus may be inserted into the recess, wherein the support apparatus together with the adjustment apparatus is already inserted into the recess during manufacture of the mattress. However, according to the invention it is also possible to retrofit existing mattresses not having a recess in the foam body. For this purpose, one advantageous further embodiment provides that the foam body is subsequently processed by introducing into the foam body a recess that is dimensioned for accommodating the support apparatus.
In the method according to the invention, a slatted frame is advantageously used as the support apparatus.
Such a slatted frame together with the electric motor-driven adjustment apparatus may be any suitable slatted frame on which an electric motor-driven adjustment apparatus is or becomes mounted, optionally also subsequently, before the slatted frame together with the adjustment apparatus is introduced into the casing of the mattress. However, the slatted frame may in particular be a slatted frame having a completely or partially integrated electric motor-driven adjustment apparatus, as known, for example, from EP 1 239 755 B1 (corresponding to U.S. Pat. No. 6,754,922 B1), EP 1 633 219 B1 (corresponding to US 2007/0220677 A1), and in particular EP 2 418 984 B1 (corresponding to U.S. Pat. No. 8,973,185 B1). The disclosed content of the publications cited above is hereby incorporated in full into the disclosed content of the present patent application by reference.
The invention is explained in greater detail below based on one further embodiment, with reference to the appended schematic drawings. All features described in the description, illustrated in the drawings, and claimed in the patent claims, alone or in any combination, constitute the subject matter of the invention, independently of their recapitulation in the patent claims or their back-references.
