Description

The present invention relates to seating and / or reclining furniture according to the preamble of claim 1.

Furniture is already known which is designed so variably that a short Remodeling the furniture other uses can be opened. Main application for so-called multifunctional furniture are sofas that turn into a bed leave and vice versa. Various embodiments are also known for this. Nevertheless, there is still room for new developments here, as it is multifunctional usable seating and / or reclining furniture still has a potential to simplify the Have handling and to increase comfort, especially lying comfort. In addition, such furniture must of course also meet aesthetic requirements, which in turn limit the possibility of functional design.

It is therefore an object of the present invention to provide an aesthetically pleasing seat and / or To create reclining furniture, which offers a wide range of variations in a simple manner and the user in all functional positions as high as possible Offers comfort.

This object is achieved by seating and / or reclining furniture with the features of Protection claim 1. Advantageous refinements are the subject of the subclaims.

The seating and / or reclining furniture according to the invention is characterized in that instead of folding, swiveling or plug-in parts, as is often the case with the prior art Multifunctional furniture can be used in the furniture according to the invention several design elements such as B. backrests, side rests, headrests, armrests or the like, find use in the body of the seating and / or reclining furniture, which has the seat and / or lying surface, are movably received, so that they are either sunk in the body or in one or more positions from the Body can be arranged protruding. This makes it easy to to create different configurations of the seating and / or reclining furniture. In particular can be achieved by completely sinking the design elements that a smooth and flat and therefore comfortable lying surface for the use of the furniture as Bed is created. For this purpose, the design elements on their top, which form a part of the lying surface with complete submergence, with corresponding Upholstery can be provided. In addition, this type of redesign offers new types creative possibilities, in particular a special aesthetic creation enable.

Advantageously, the design element is, for example, a cuboid Can have basic shape, spaced from the edge of the body, so that the Corpus has sufficient stability, especially in its edge area, in order to To be able to guide the design element in its preferably translatory movement. The cuboid basic shape has the advantage that the top of the design element can be formed as part of the seating and / or lying surface, that is also a corresponding one Can have padding.

In a preferred embodiment, the design elements are also complete recorded in the body so that they do not close from the outside when retracted are recognizable. This has the advantage that the design elements, such as backrests, Armrests etc. disappear completely when converting the sofa into a bed and also not dismantled and stowed in another way.

A movement mechanism is advantageously used to move the design elements provided that moves the design elements as automatically as possible. Preferably only one handle is required to trigger the movement mechanism To start the movement mechanism. In addition, the movement mechanism possibly completely included in the body with the exception of an actuator his

For example, this can be achieved in that the design element in one Prestressed position, preferably in the first position in which the element is retracted is so that it automatically moves to the second position after releasing a lock is moved into the extended state. A mechanism can be used for this as it is used for example in office or desk chairs. This have for this purpose a gas spring with which the height of the seat height is continuously adjustable can be, the seat height is fixed at any height by locking. In a corresponding manner, the design element can be used with such a movement mechanism like, e.g. B. a backrest, continuously between a retracted position, in which the design element ends with the seating and / or lying surface, and a maximum extended position, the design element at any height can be locked. This stepless adjustment and locking still allows more varied use of the furniture. For example, a side back can be used as a Backrest and use as a headrest. To do this, all you have to do is different Heights of the side back can be adjusted. In addition to gas springs, of course, also come other mechanisms, such as B. mechanical springs or tension mechanisms where the design element is automatically moved downwards by gravity and is brought into a raised position by the user, where it can also be locked can.
