Abstract

The invention relates to an orthopedic pillow which adapts itself better to the body. The aim of the invention is to provide a pillow which is both comfortable and supports the body in any position. To this end, a form-cut, preferably reticulated, viscoelastic foam which itself adapts well to the body is used. The pillow is raised in the neck area and adapting sections are cut into the raised part in the shapes of slats, cylinders or similar. These sections can then be completely or partially removed or replaced with softer or harder or larger sections. As a result, the pillow is more adaptable. According to another method for producing the pillow in claim 3, fig.2, the pillow consists of a foam core which is covered with a layer of a soft, preferably also reticulated foam with raised fibres, in such a way as to improve the exchange of air and heat. The head rest part of the pillow according to claim 2 can be cut in accordance with claim 7 so that it bends more easily and adapts better to the body in a side position.

Description

ORTHOPEDIC PILLOW

2 Description:

The invention relates to an orthopedic pillow according to the preamble of claim 1, made of a viscoelastic polyurethane foam, which is already on the one hand by the

Body heat adapts better to the body and which, on the other hand, can also be easily adapted to the body thanks to incised profiles in the neck bulges, and moreover

is preferably made of reticulated foam, which is much more breathable and therefore less sweaty. Viscoelastic foam and reticulation are terms that are generally known to every foam specialist.

Human health and well-being are also generally of a restful sleep

dependent. The head, neck, shoulder and spine must be optimally positioned so that the body can relax properly. Because in this game too people are different

Have mass, the pillow must be individually adaptable to the body. The need for the hardness of the pillows is also individual. Many well-known pillows, especially those made of foam, are usually too warm, so you can sweat easily.

Pillows are also known that can only be insufficiently adapted to the body.

Normal foams adapt less well to the body because of their cross-linking

have a higher surface tension. This creates a contact pressure.

Viscoelastic foams become very adaptable and fit through body heat

the body with the lowest contact pressure. So that the head is optimally supported,

an orthopedic pillow lying on its side in the neck area must be raised;

lie. In the supine position, the neck area should generally be less thick in the middle of the pillow. The purpose of this invention is to provide pillows that do all of these

Meet requirements. 3 According to claim 1 of this invention, neck / neck areas of the pillows are increased by beads which have incised fitting profiles. These internal profiles can be easily removed or partially removed. According to claim 2, these profiles can also be replaced by firmer or thicker or thinner. For example, in the

A piece of any length (usually about 15 cm) from this profile can be removed with a pair of scissors so that the pillow is less thick in this area. Should that

Pillows in the neck area in general or at any point can become harder or higher

a firmer or thicker standard profile can be used. If it is to be thinner, the profile can be removed. In conjunction with the viscoelastic foam, the adjustment profiles offer all the options necessary for an individually adaptable, orthopedic pillow.

Generally, polyurethane foams are too warm because of the partially closed cells

and easily cause sweating. Foams have been available for years

reticulate so that they become much more open-celled and thus offer better air permeability. This method has not been used in the pillow area. Because that

Problem of sweating is known, according to this invention is preferred for this

new pillow reticulated foam used, which is a much (up to 5 times) better

Offers air permeability.

Since the needs for sleeping and the demands on a pillow are different, should

these pillows are made in different designs.

So the pillow according to claim 1 and Fig. 1, preferably consist of one

viscoelastic, reticulated, form-cut solid foam block, with two elevations, so-called neck bulges with adjustment profiles. 4 According to claim 2, a pillow is described, the profiles of which can also be replaced by higher or firmer ones, whereby the pillow can also be made taller or firmer on request

can be.

Another pillow according to claim 3, Fig. 2, consists of a core of this foam according to claim 1, with only one neck bead with a matching profile and a headrest. This foam core is additionally covered with a layer of foam, which is preferably

is also reticulated and can have pimples, which even significantly improves the air permeability. According to claim 4, this layer can even be removable.

As a result, the adaptation profiles are more accessible and are therefore more adaptable or interchangeable.

According to claim 5, Fig. 4, another pillow is circumscribed and represented, which on one side,

is cut much deeper. This allows the pillow to be more individual to the body almost over the entire surface with different types of inserts, such as plates or wedges, etc.

can be customized.

According to claim 6, Fig. 3, a pillow as described in claim 1, which is for the

Neck area has two ridges / beads with matching profiles, the beads having a different thickness. By turning the pillow, the

higher or lower bead can be used, which allows an even better adjustment

becomes.

When sleeping, the body is mostly lying on its back. Will he turn left or right

rotated, there is a slight radius. Normal pillows are currently in use and also fit there

Body too little. So that this pillow can better adapt to the body in the side position, according to claim 7, Fig. 5, the headrest of the pillow core above the

Cut the neck area several times so that the pillow can be bent more easily. Exemplary embodiments of the invention are described below with reference to the accompanying drawings. Show it

Fig. 1 shows a pillow according to the invention with matching profiles.

Fig. 2 shows a pillow according to the invention consisting of a foam core with a neck bulge

with an adaptation profile, with a headrest and a foam cover with knobs, according to claim 3, which according to claim 4 can also be removable.

Fig. 3 shows the pillow according to claims 1 and 6 with different bead heights, so

that the desired height can be selected by turning.

Fig. 4 shows a pillow according to claim 5, which is deeply cut so that it can be adjusted almost over the full area.

Fig. 5 shows the foam core according to claims 1 + 3, the additional in the headrest

according to claim 7, has incisions so that it can be bent more easily.

Claims

6 claims

1. Orthopedic pillow which consists of a shape-cut, viscoelastic polyurethane foam Fig. 1, which is preferably reticulated, that for the neck area

Has ridges which have cut in the inside of lath-shaped or cylindrical or similar fitting profiles, which can be removed in whole or in part, if desired,

which makes the pillow thinner and softer in this area.

2. Orthopedic pillow according to claim 1, but that the adjustment profiles also against

other profiles can be exchanged, whereby the pillow can be made thicker or firmer in the neck area.

3. Orthopedic pillow according to claim 1, but consisting of a foam core with a bead with a matching profile and a headrest, which also with a layer

soft, preferably also reticulated foam is covered with knobs, so that between the pillow core and the soft foam cover a better air and

Heat exchange takes place. Fig. 2

4. Pillow according to claim 3, however, that the soft cover foam is removable, so that

the foam core is more accessible for adjustments.

5. Orthopedic pillow according to claims 1 and 3, but that this one-sided

is cut deeper (Fig. 4) and can therefore be adapted almost over the entire surface and for which purpose other adaptation profiles can also be used. (Plates / wedges).

Has ridges / beads with matching profiles, so that by turning the higher or

the lower bead can be used. Fig. 3

7. Pillow according to claim 2, the headrest has incisions in the pillow core above the neck area, so that it can be bent more easily. Fig. 5
