Foam inner core of upholstery for seating and / or reclining furniture

专利摘要:
A foam inner core of upholstery for seating and / or reclining furniture consists of wave-shaped longitudinal (31, 32) and transverse webs (41, 42, 51, 52), the waves of the longitudinal (31, 32) and transverse webs (41, 42, 51, 52) are interlinked. There are two layers (1, 2) with interlocked waves of the longitudinal (31, 32) and transverse webs (41, 42, 51, 52) connected to each other superimposed, wherein the wave crests of the layers (1, 2) face each other , This improves the suspension comfort.

专利说明:

The invention relates to a foam inner core of upholstery for seating and / or reclining furniture, which consists of wave-shaped longitudinal and transverse webs, wherein the waves of the longitudinal and transverse webs are interlocked.
Foam upholstery is used both for mattresses in beds and for seating furniture that can be convertible into reclining furniture. Such foam padding consists of a foam inner core and various editions and coatings of a non-woven and / or fabrics.
In order to improve the suspension comfort of foam upholstery inner cores have already become known with the features mentioned. These inner cores with very good suspension properties have already proven very well in practice.
The invention has set itself the goal of creating a foam inner core of the type mentioned, the suspension comfort is further improved.
This goal is achieved in a surprisingly simple manner in that two layers with intermeshed waves of the longitudinal and transverse webs are connected to each other superimposed, wherein the peaks of the layers face each other.
As numerous experiments have proven, in a core according to the invention the comfort of the foam padding is actually improved.
In the context of the invention, it is possible that the opposing peaks of the two layers touch each other and are glued together.
In another embodiment of the invention, an intermediate layer is arranged between the two layers, with which the wave crests of the layers are glued.
Within the scope of the invention, it is possible that the two layers have different properties, e.g. Hardness, have. Thus, a padding (mattress) e.g. medium strength and solid.
The invention will be described in more detail with reference to exemplary embodiments illustrated in the drawings, without the invention being restricted to these examples.
Showing:
Figure 1 is a perspective view of an inventively designed inner core of a padding for sitting and / or lying furniture.
FIG. 2 is an enlarged view of a side view of an inner core of another embodiment of the invention; FIG.
Fig. 3 is a side view of the inner core of Figure 2 from the narrow side.
4 shows a perspective view of a further embodiment of the foam inner core according to the invention;
Fig. 5 also in perspective view of another embodiment of an inner core according to the invention.
According to FIG. 1, an inner core according to the invention consists of two layers 1 and 2. The layer 1 has longitudinal webs 3i which are intertwined with transverse webs 4i, 5i.
The layer 2 lying above the layer 1 has longitudinal webs 32 which are intertwined with transverse webs 42, 52.
In both layers 1 and 2, the longitudinal webs are interwoven with the transverse webs such that the troughs of the longitudinal webs engage in the peaks of the transverse webs and the peaks of the longitudinal webs in the troughs of the transverse webs. This is known per se.
As can be seen from the drawing, in particular have the transverse webs 4lf 42, 5i, 52 in different areas of the inner core of a different cross-section. It is thereby achieved that an adaptation to the body of the person lying on the upholstery is achieved by changing the cross sections of the longitudinal and / or transverse webs.
The opposite wave peaks of the layers 1 and 2 point in the embodiment of FIG. 1 in the same direction. According to FIGS. 2 and 3, the wave crests of the layers 1 and 2 are facing each other.
In the embodiment according to FIGS. 2 and 3, therefore, the two layers 1 and 2 can be connected to one another in that the wave crests of the two layers are glued together at 6.
In the embodiment according to FIG. 1, the wave crests of the longitudinal webs of one layer (1 or 2) are glued to the transverse webs of the other layer (2 or 1).
Upper and lower cover plates 7 envelop the existing of the two layers 1 and 2 inner core.
The layers 1 and 2 of the inner core of Fig. 4 correspond to the layers 1 and 2 of the embodiment of FIG. 1. It is different that on the surface of the layer 2 stiffening bands 8, 9 attached, preferably glued, are. This achieves an increase in dimensional stability.
In the embodiment according to FIG. 5, an intermediate layer 10 is arranged between the two layers 1, 2. With this intermediate layer 10, the wave crests of the layers 1, 2 are glued. The structure of the layers 1, 2 otherwise corresponds to the structure of the layers 1, 2 according to FIGS. 1 and 4.
Numerous modifications are possible within the scope of the invention. So the term "foam " In the broadest sense to understand, in particular also fall latex inner cores are within the scope of the invention.
