Description

Adjustable upholstery device for seating and / or reclining furniture

The invention relates to an adjustable upholstery device for seating and / or reclining furniture.

Upholstery devices for seating and / or reclining furniture are generally known, for example, in the form of a combination of a separate mattress with a separate slatted frame. A disadvantage of this known combination of slatted frame and mattress is that the slatted frame is generally not matched to the mattress in its suspension properties. This leads to a loss of comfort for the user.

Furthermore, adjustable slatted frames are known which have adjustment means for adjusting at least a part of the slatted frame in terms of its inclination and / or its height. However, these slatted frames are used with separate mattresses, so that again no matching of the mattress to the slatted frame is possible and therefore there are also losses in comfort for the user.

The invention is based on the object of specifying an upholstery device for a seating and / or reclining furniture, in which the comfort and the ergonomic properties are improved.

This object is achieved by the teaching specified in claim 1. The basic idea of the teaching according to the invention is is to connect the padding element, for example a mattress, with the support device, for example a slatted frame, and the adjusting means to form a unit. In this way, an optimal matching of the support device to the upholstery element is made possible and thereby the comfort for the user is improved. The thickness of the upholstery element can, for example, be chosen such that the suspension properties of the upholstery device are primarily determined by the suspension properties of the support device. In addition, the padding element can be adapted to the adjustment options of the support device.

Since the upholstery element is connected to the support device, transport and handling are considerably simplified compared to conventional upholstery devices in which the upholstery element and the support device are designed as separate units. The upholstery device according to the invention is simple and inexpensive to manufacture and can be used in a variety of ways.

The connection of the upholstery element with the support device and the adjusting means to form a unit can, for example, take place in that the or each upholstery element is detachably connected to the support device and that holding means are provided for holding the or each upholstery element on the support device, as is an expedient development of provides teaching according to the invention. The holding means can be designed in any suitable manner.

A particularly advantageous development of the teaching according to the invention provides that the or each padding element is firmly connected to the support device. is bound. In this way, the structure of the upholstery device according to the invention is particularly simple. The padding element and the support device can be firmly connected to one another in any suitable manner in the manufacture of the padding device according to the invention.

A further development of the aforementioned embodiment provides that the or each padding element is glued or foamed onto the support device. In this embodiment, the manufacture of the upholstery device according to the invention is further simplified.

Another development of the teaching according to the invention provides that the adjustment means are arranged essentially completely between an upper boundary plane and a lower boundary plane of the support device. In this way, the adjustment means do not protrude above the support device, so that there is only a small overall height of the support device and thus also of the upholstery device.

The adjustment means can be designed in any suitable manner. The adjustment means expediently have at least one electromotive adjustment drive, in particular at least one linear drive. Linear drives in particular are available as simple, inexpensive and robust standard components, so that the upholstery device according to the invention is, overall, inexpensive and robust. Another development of the invention

Teaching provides that the base body has longitudinal spars spaced from one another and transverse spars at its ends in the longitudinal direction and that the longitudinal spars and / or the transverse spars on their side face the cushioning element. facing side have support surfaces made of an elastic material on which the padding element rests. The suspension properties of the upholstery device can be influenced by appropriate selection of the elastic material.

In the aforementioned embodiment, the contact surfaces are expediently designed in the form of strips.

Another expedient development provides that the base body, on its side facing the padding element, has spaced, resilient slats, in particular made of wood, on which the padding element rests. In this embodiment, the support device is designed in the manner of a slatted frame.

An extremely advantageous development of the embodiments with the support surfaces and the slats provides that recesses are formed in the support surfaces, into which the slats engage with their free ends. In this embodiment, the slats are held between the base body of the support device and the cushioning element, so that separate holding means for holding the slats on the base body are not required. This simplifies the structure of the upholstery device and makes it more cost-effective to manufacture.

In the aforementioned embodiment, the recesses are advantageously shaped essentially complementary to the free ends of the slats, so that the slats are held in a form-fitting manner in the recesses. Another expedient development of the embodiments with the support surfaces and the slats provides that the surfaces of the ends of the slats facing the cushioning element with the adjacent support surfaces. essentially aligned. In this embodiment, the ends of the slats with the adjacent support surfaces form a continuous support surface for the upholstery element, which, for example, can be glued onto this continuous support surface and can thus be securely connected to the support device.

In principle, it is possible to provide elastic material between the slats and the longitudinal spars of the base body and thus to influence the suspension properties of the upholstery element. However, the slats expediently rest on the longitudinal spars of the base body, so that the longitudinal spars form the support for the slats and the suspension properties of the upholstery device are therefore exclusively dependent on the spring properties of the slats and the upholstery element.

In the embodiment with the contact surfaces made of elastic material, the elastic material is expediently a plastic foam, as is provided by an embodiment. This further simplifies the manufacture of the upholstery device according to the invention.

The longitudinal spars and / or the transverse spars can also be foamed with the plastic foam, as is provided in one embodiment.

The shape, size and structure of the basic body of the support device can be selected within wide limits. The base body of the support device expediently has a first support part and at least a second support part for supporting the padding element in a planar manner, the first support part and the second support part being connected to one another in an articulated manner and being pivotable relative to one another by the adjusting means. In this embodiment, the first support part and O to H ^{1 1}
