Description

The invention relates to a motor-adjustable upholstered furniture. Motor-adjustable upholstered furniture is already known. For example, the shows DE 10 2012 112 905 A1 a motor-adjustable upholstered furniture. A disadvantage of known motorized upholstered furniture is that they are expensive to manufacture and / or their visual appearance is impaired.

The invention has set itself the task of creating a motor-adjustable upholstered furniture, which is improved in terms of at least one of the disadvantages mentioned.

This object is achieved by the recited in claim 1 motorist adjustable upholstered furniture.

The motor-adjustable upholstered furniture according to the invention has a padding, a motorized adjustment and a reference. At least one switch is provided for actuating the motorized adjustment. The at least one switch comprises at least one built-in switch or is formed by at least one built-in switch, which is concealed in the upholstered furniture integrated. The term "hidden" means in the context of this document in this context in particular, that the built-in switch is not directly accessible from the outside. In this way, the built-in switch, as preferred, be arranged from the outside at least almost invisible. The visual appearance of the upholstered furniture is not affected in this way by the built-in switch.

The upholstered furniture may for example be a chair or a sofa.

The padding may include foam.

Advantageously, the built-in switch can not be removed from the upholstered furniture or folded out during normal use.

The built-in switch is preferably concealed by the upholstery of the upholstered furniture. The built-in switch is preferably arranged within the cover. Advantageously, the built-in switch between the cover and upholstery is arranged.

The cover can also be referred to as upholstery. The cover preferably comprises fabric or is formed from fabric.

In the preferred embodiment, the built-in switch is a pressure switch. With a "pressure switch" is referred to in the context of this document, in particular a switch, in which the switching operation requires a force exerted by the user, unlike a so-called "touch switch". The pressure switch is preferably a so-called snap switch. The pressure switch preferably comprises a circuit board and at least one push-button switch, preferably according to the snap-frog principle, that is to say with a force-displacement characteristic which exhibits pronounced hysteresis. The pressure switch preferably comprises a plurality of pushbutton switches, preferably four.

If the built-in switch is floatingly mounted on the upholstered furniture, then a prerequisite for a particularly cost-effective manufacturability of upholstered furniture is created. With the term floating storage is meant in the context of this document, in particular, that the built-in switch in Can relocate operation. Preferably, the entire installation switch is floating. Preferably, the built-in switch movable elements that are movable to the other built-in switch and the entire built-in switch is floating. Advantageously, the built-in switch is supported by the padding. The acting on the built-in switch actuating reaction forces are preferably effected by the padding. The switch may abut the padding and be held by the cover on the padding.

Advantageously, no substructure is provided for the built-in switch. It is therefore preferred in particular no rigid element between the built-in switch and the frame of the upholstered furniture provided, which causes the actuation reaction forces. As a result, the production can be simplified.

Even if the upholstered furniture has a frame, the built-in switch is therefore not connected to the frame with advantage.

The built-in switch advantageously has no housing. This creates a prerequisite for further cost savings. Also, the comfort can be increased thereby.

Preferably, the built-in switch is arranged in a pocket. In principle, it is conceivable that this bag is arranged inside the cover. Preferably, however, this bag is not arranged directly on the cover.

If the built-in switch is arranged on an insert, which is advantageously firmly connected to the upholstered furniture, then a particularly visually appealing upholstered furniture can be created. The insert is preferably planar. The insert is advantageously limp and comprises, for example, fabric or foil, in particular plastic foil, or is formed as a result. This allows it to fit harmoniously into the upholstered furniture.

The insert is preferably connected to the cover, preferably sewn. Advantageously, the insert is so large that it is present by means of the already existing on the cover Seams are sewable. The insert is sewn with advantage exclusively by means of hidden seams with the cover. In the context of this document, the term "hidden seams" refers in particular to seams which are either required anyway on the cover, ie are visible to the user, but do not indicate the use or which are invisible to the user in ordinary use Place, about under the upholstered furniture, are arranged. As a result, the visual appearance of the upholstered furniture is not affected by the built-in switch and the production can be simplified.

The bag is preferably arranged on the insert. The bag is advantageously connected to the use, such as sewn, glued or welded. In the embodiment in which the insert is formed of foil, the pouch is advantageously glued or welded to the insert. The bag may be formed of film, in particular plastic film. Advantageously, the pocket is arranged on the inside of the insert, ie the side facing inwards in the upholstered furniture insert. The insert may have a bulge - in a film about an embossing - in which the bag is arranged. The built-in switch is preferably inserted through an opening in the pocket of the bag. The bag can be provided at least slightly elastic.

The bag preferably has a self-locking opening. The bag may have an approximately rectangular cross-section. The opening preferably extends obliquely on one side of the pocket, preferably not over the entire side. The opening thus preferably leaves an edge on the side of the pocket on which it is arranged. The built-in switch is preferably obliquely inserted through the opening in the pocket and straightened in the bag. After straightening in the pocket of the built-in switch is preferably prevented by this edge from slipping out of the bag.

Advantageously, Tasthilfen be provided on the upholstered furniture that allow or facilitate a palpation of the built-in switch. The Tasthilfen are advantageously not directly attached to the switch. The Tasthilfen are preferred as the rest of the built-in switch, hidden - in particular by the reference - in the upholstered furniture arranged. Advantageously, the Tasthilfen are arranged on the insert, about embedded. And the built-in switch is preferably positioned on the insert in such a way that the touch aid lies above a pushbutton switch. The inserted into the insert Tasthilfen press so preferred to trigger on the underlying Knack frogs of the built-in switch. The push buttons preferably include rivets. The Tasthilfen preferably serve simultaneously the power transmission to the built-in switch.

In one embodiment, the touch aids do not directly contact the pressure switch. The Tasthilfen and the pressure switch can be separated by a wall of the bag and this wall of the bag can be pressed in the switching operation by the Tasthilfen against the push-button switch and operate them.

Advantageously, in the upholstered furniture no recess - in its padding - incorporated, in which the built-in switch is arranged. It has been shown that this can be dispensed with, which can facilitate the manufacturability of upholstered furniture and increase comfort.

The built-in switch is preferably used to trigger the motorized adjustment of the upholstered furniture. Preferably, the upholstered furniture on motor fittings, which can be actuated or triggered with the built-in switch.

The built-in switch is preferably not mounted in a housing from the outside in the frame of the upholstered furniture, but preferably, as already mentioned, incorporated in a plastic bag in the cover. He is thus preferably hidden and placed particularly flexible between cover and upholstery. As a result, the built-in switch is arranged protected and it can be facilitated the replacement of the built-in switch in case of malfunction.

The built-in switch does not hinder the comfort and can be used universally, for example, between two seats.

The Fig. 1 to 4 show the switch 3, which is designed as a built-in switch 4, more precisely as a pressure switch 5. The pressure switch comprises a circuit board and push-button switch according to the click-and-click principle. In the illustrated embodiment, four push-button 10, 10 ', 10 ", 10'" are provided. The pressure switch is with a Cable 9 provided. The pressure switch 5 has in the illustrated embodiment, a length L of about 9 cm and a thickness of about 3mm. The built-in switch 4 triggers the motor fittings, not shown in the figures, of the upholstered furniture.

In the illustrated embodiment, the pressure switch 5 is disposed on an insert 6, which inter alia in the FIGS. 5 and 6 is shown. The insert 6 is formed in the illustrated embodiment of fiber-reinforced film. Fig. 6 In the embodiment shown, the insert 6 has a rectangular shape, with a longer extension E of about 20 cm and a shorter extension K of about 15 cm.

Approximately Fig. 5 shows that a pocket T is arranged on the insert 6. The bag is also made of foil. It is welded to the insert 6.

Fig. 7 lets recognize the hidden integration of the built-in switch 4 in the upholstered furniture 100. The insert 6 is sewn directly into the cover 2. In partially dashed lines, the position of the insert 6 with the pocket T and with the built-in switch 4 is indicated. The built-in switch 4 can not be touched directly from the outside. He is covered by the cover 2 of the upholstered furniture. He is floating on the upholstered furniture 100 stored. The forces exerted by the user to effect the switching operation on the pressure switch 5 forces are absorbed by the padding 1 of the upholstered furniture. Depending on the hardness of the padding and the size of the forces exerted, the pressure switch 5 is displaced more or less strongly inwardly into the upholstered furniture during the switching operation and then returns to its original position.

The insert 6 is sewn to the cover 2. Fig. 7 also shows that the insert is sewn exclusively to the cover 2 by means of hidden seams, namely by means of the already required seams N1, N2 of the cover 2. The course of these seams N1, N2 on the insert 6 is in FIGS. 5 and 6 shown in dashed lines.

Fig. 8 1 schematically shows a cross-sectional view through the upholstered furniture 100 in the area of the pressure switch 5. It can be seen that the pressure switch 5 is arranged in a pocket T, which in turn is arranged on the insert 6, which is arranged on the continuous cover 2. From the outside A of the upholstered furniture, the pressure switch 5 is not visible (see also Fig. 7 ). The insert 6 is thus directly between the cover 2 and the pad 1, here the seat foam. In addition, it can be seen that the button aids 7 are embedded in the insert 6 at the height of the pocket T, this pass through, the bag T in the embodiment shown, however, do not pass through. Tasthilfen 7 and pressure switch 5 are therefore separated by a layer of the bag and the bag is pressed in the switching operation by the Tasthilfen against the push-button switch and actuates it. The Tasthilfen 7 touch the pressure switch 5 so not immediately.

Fig. 9 schematically shows the pocket T of an embodiment in which the pocket T has a self-locking opening 11 through which the pressure switch 5 is inserted. The opening 11 extends obliquely and with curved edges. It does not extend over the entire side of the pocket T but leaves an edge R, which prevents the pressure switch 5 in the inserted state from slipping out.
