Cushions for upholstered furniture

The innovation concerns a cushion for upholstered furniture, ordered from a cushion cover divided into chambers by dividers, the chambers of which are each filled with a plastic foam core covered by a polyester fiber fleece. These cushions for upholstered furniture are known in the trade as so-called "fiberfill cushions".

There are two different types of these "fiber fili pillows". at One way, the compartmentalized cushion covers are completely filled with polyester wadding, the polyester wadding or the polyester fiber fleece for each chamber in a corresponding manner Cut to width and run into a relatively thick strand, is inserted into the cushion cover from the side. The disadvantage of these pillows is that the polyester wadding easily compresses a little over time, especially but there is no resilient mass that repeatedly tensions the cover fabric that surrounds the cushion cover.

Such cushions are known for which a polyether foam have as a middle layer, the polyether foam being cut to size in blocks and wrapped in polyester fiber fleece. This Polyester fiber fleece can be glued on and can also simply be wrapped around the middle layer.

The disadvantage of these "pillows" is that these pillows no cuddle, e.g. like a down pillow exhibit.

The innovation is based on the task of a cushion for upholstered furniture and the like, in which a high degree of softness is given and this in the overall upholstery depending on the different Load is precisely tunable.

The innovation is that the core of the pillow chambers is built in sandwich construction in layers, with one load-bearing Middle layer is enclosed by layers with lower compressive strength. This makes it possible to have the particularly soft chambers to be upholstered with layers in the plastic foam core to be provided that have an exceptionally low compression hardness during chambers that are subject to heavy use, for example in the seat cushion area, a different sandwich construction is obtained, for example by adding the middle layer has a greater compressive strength than the middle layer of the cores of the back cushion and also the upper and lower layers are designed differently.

Another very important idea of the innovation is that the core has a supporting polyether layer in the middle, applied to the top and bottom layers of foam rubber stickware are.

The main advantage of foam rubber pencils is that they that it is permeable to air, through the pin holes and also through the porous foam. This is a very pleasant one Sitting feeling available, apart from the fact that the foam rubber penware has an extraordinarily large degree of softness and practically replaces a down filling. This core is also covered with polyester wadding.

Instead of applying layers of foamy gum to the load-bearing polyether layer in the cement above and below oine Layer of the same material, also made of polyether, is applied However, these layers must have a lower compressive strength than the vibrating layer 6.

It is extremely advantageous to use the cores for the seat cushion each in sandwich construction, but for the back cushion only the lower core 5 in sandwich construction build up. The two upper cushions of the back cushion should be made entirely of latex pencils or foam rubber pencils. The pin holes 5 'of these cores are in the direction of the load The back cushion and the back cushion not only give the back cushion extremely good snugness, but at the same time a great air permeability. especially o ^ r latex foam is poured open-pored.

Furthermore, it is possible to design the individual cores differently in their oandwich-Bpuweiso and to adapt them to the respective load, also with regard to the thickness of the individual layers. It is advantageous to build up the core as it is ir 3 ¹ It ;. 2 is shown such that each layer releases one third of the holie when the core is relaxed.

Of course, the 4th thought of the innovation is not up limited to the embodiments shown and described, each layer of the cores, e.g. from Savings reasons for their part composed of individual layers will.
