Abstract

An upholstered seat, bed or couch has a foam rubber or foam latex core whose outer surfaces bear stiffening straps (6, 7, 8) bonded to the surface. The foam incorporates cuts and cutout sections.

Description

Interior upholstery core consisting of cellular plastic or latex.

The invention relates to an inner core, which is made up of cellular plastic or latex, upholstery for seats and / or reclining furniture.

Such interior upholstery cores, by For example, "cellular rubber mattresses" have many advantages; they are, in particular, lighter than elastic cores and also easier to process than elastic cores. A disadvantage is its dimensional stability, frequently unsatisfactory

Document DE19700131A1 describes a children's mattress, whose cell body is provided with grooves that they are embedded in the contours of a stepped edge and can insert into stepped edges in a loose and non-adhesive manner. The stepped edges are constituted, in this case, by Hardened cellular plastic as a mattress body. It can not achieve increased dimensional stability by means of a This type of design.

The document FR-A-1294879 describes a similar arrangement.

The objective of the present invention is to create a inner core of the type indicated above that has a dimensional stability much greater than the inner cores known. This is achieved by setting reinforced bands, preferably bonded by adhesive, to the edges at least in the surface of the seat and / or reclining. Numerous experiments have shown that a great increase in the dimensional stability of the inner core through these bands reinforcement attached.

In a practical example of this invention, the inner core shows on both surfaces incisions arranged parallel to each other, both in the longitudinal direction and in transverse direction, extending the incisions of a surface between the incisions of the other surface and overlapping the incisions of both surfaces with each other. At case of an inner core formed in this way, openings are created through the incisions crossed with each other, openings that guarantee a sufficient ventilation and / or aeration of the inner core.

In the case of another embodiment appropriate of the invention, the inner core is constituted by longitudinal and transverse crossbars of wavy type shape and the undulations of the longitudinal and transverse crossbars They are geared in a denticular manner. The upholstery with a inner core formed in this way has better properties of resilience and ventilation from which they could be obtained previously.

Next, the invention is described with more detail through the practical examples represented in the drawings without being limited to these examples.

Fig. 1 represents an inner core according to the invention with a partially removed cover panel; Y

fig. 2 shows another embodiment of an inner core according to the invention.

According to figure 1, an inner core 1 is consisting of longitudinal crossbars 2, 3 and crossbars 4, 5 transversal. All longitudinal crossbars 2, 3 and Transverse crossbars 4, 5 have a wavy type shape. The longitudinal crossbars 2, 3 rotate 180º face to face at the longitudinal crossbars 3 and crossbars 4 se rotate 180º face to face to the transverse crossbars 5.

The longitudinal crossbars 2, 3 are geared with transverse crossbars 4, 5 (and vice versa) of such that the shape of the inner core 1 shown in Figure 1

The reinforced bands are joined by adhesive to at least the edges of an inner core surface  1, in figure 1 the reinforcement bands 6, 7 and 8 are observed. medium of these reinforcement bands achieves high stability dimensional of the inner core 1.

The reinforcement bands may be constituted by different materials, either plastic or metal. In an example Practical preferred, may be constituted by polypropylene.

The upper and lower cover panel 9 and the side covering bands 10 (of which only drawn a part in figure 1) wrap the inner core one.

According to Figure 2, an inner core 11 has a surface 12 and a surface 13. Surface 12 is provided with incisions 14 that run in the longitudinal direction and with incisions 15 that run in the transverse direction.

Surface 13 has incisions 16 that run in the longitudinal direction and with incisions 17 that They run in a transverse direction. Incisions 14 and 15 of the surface 12 extend downward on the central surface 18 of the thickness of the inner core 11 and incisions 16 and 17 are extend upward over the central surface 18 of the thickness of the inner core 11.

In this way, incisions 14 and 15, in each case, between incisions 16 and 17, and vice versa.

The cover panels 19 cover the core inside 11 above and / or below.

The reinforcement bands 21, 22 and 23 are joined by adhesive to surfaces 12 and 13, in particular, without However, to surfaces 12, whose adhesive bands perform the fastening of the inner core parts 11. Obviously, a reinforcement band is also present on the side of the core interior 11, which is not visible due to the cover panel 19. In this practical example the reinforcement bands can also be constituted by different materials.
