Headrest, especially pillow, Head pads and the like.

( In the manufacture of headrests, such as pillows and head cushions

and the like. In recent times one serves oneself to a greater extent an elastic mass with a generally cellular texture, which is usually covered with a textile cover. As such Masses are usually latex foams or plastic foams are used on an elastic basis. When using this natural or Artificial masses, however, are generally only assumed to contain the previously common fillers such as wool, cotton, feathers, etc. to be replaced by an elastic cellulose pulp. As a result has you have practically the same shape and dimensions

retained that of the previously customary fillers were used. It is true that the use of elastic fabrics of this type results in a cellular texture in the industrial manufacture of head pads Whole range of economic advantages, dooh it must be admitted that these advantages very often turn out to be detrimental With regard to the convenience and safety of users and consumers. As is known, is in in many cases the elastic response of such an elastic fabric with a cellular structure is so strong that the headrest is elastic at the load point deformed, but often an uncomfortable reaction force is formed. This becomes very uncomfortable and annoying The excessive elasticity of the filling material is felt especially when you sleep on it Wants to turn the pillow around. In fact, the sleeper very often feels such a strong elastic pressure that result in sleep disorders for very specific head positions. This inconvenience is exacerbated by the fact that the User, as soon as he has found a balanced position for his head on such a pillow, constantly trying will be not to change this position, otherwise he feared the disturbing retroactive effect of the headrest got to.

In general, this relatively violent reaction is more of a kind Headrests therefore «that when the filling compound with a cellular structure is pressed together, those in the cells Trapped air, as far as it is a question of cells that are closed on all sides, is compressed, or if it If the cells are open, numerous cells close completely or partially due to elastic deformation

and thereby systematically prevent a normal discharge of excess air, so that the volume of the underlying Cell mass insufficient or only sufficient under physical exertion can be reduced.

The innovation wants to remedy the disadvantages shown and goes assuming that it is not enough to use a well-known material, i.e. the filling of a cushion with a new one Material, e.g. latex or plastic foam, can easily be replaced, but that with such a material exchange the material properties are taken into account mttssea.

The headrest according to the invention therefore has the pillow filling forming elastic mass at the point of support of the head a relatively deep, on both sides of a relatively indentation limited by a strong bulge.

This novel shape means that a large part of the elastic deformation inherent in the previous designs is eliminated replaced by a special morphology so that the reaction force of the elastic compressed by the head of a user Filling mass is reduced considerably. In addition, the head finds rope systems * which are completely new and through which the head can assume extremely comfortable positions, which result in excellent balance lead, because the upper part of the spine always occupies the physiologically and anatomically best position, indifferent whether the sleeper lies on his side or on his back

Such a cushion filling can be appropriately profiled, for example, by foaming latex or plastic Making shapes. On the other hand, this could be

Ej.ne more detailed explanation of the innovation results from the following description of some preferred embodiments with reference to the drawing with lie conditions; show it:

Figure 1 is a headrest according to the innovation in perspective Depiction;

Figure 2 shows a second embodiment of such a game Headrest;

FIGS. 3 and 4 show a further variant; and

Figure 3 is a perspective view of a double head upholstery

The head cushion according to the innovation shown in FIG. 1 consists of a filling compound 1 and a coating 2. In the exemplary embodiment shown, the film compound 1 has a flat underside J, two lateral elevations or beads 4, respectively. 5 and a central indentation 6 between them. The mean width L of this indentation 6 is determined by the requirement that a user can easily place his or her head in the indentation without any hindrance, ie without any squeezing. The side surfaces 7 and 8 ″, which go down from the sleeves 4 and 5 to the bottom of the indentation 6, generally run at an oblique angle, with no sharp-edged incisions being provided anywhere, but the individual surfaces over such KrOmmmm ^ mm. merge into one another that no contact with the

any inconvenience or cushioning with your head make disturbing influences for the ß * m> -zer noticeable.

The embodiment according to FIG. 2 corresponds essentially to that from Figure 1 with the exception that on the back be between the top or rear edge of the headrest, the two beads 4 and 5 connecting wall piece 9 is formed, so that the indentation 6 does not extend over the entire Width or height of the headrest extends, but is closed at the top or rear edge of the same. One Such a shaping can appear particularly advantageous above all when due to the softness of the filling compound excessive deformability of the headrest as a result of the deep indentation 6 is feared.

The head cushion shown in Figures 3 and 4 is in two parts and consists of a head cushion corresponding to FIG. 1 and a filler piece filling the indentation 6 thereof 10. Both parts are designed as separate cushions, i.e. the filling compounds 1 and 10 each have a corresponding one coating 2 provided. The filling cushion 10 filling the indentation 6 of the actual headrest is only used when you like a continuous surface would like to receive with a conventional upholstery. This special training gives you three application options, namely, once a head cushion, which fulfills the requirements underlying the innovation to a full extent, then a cushion in the usual manner and the additional or filled 10 as a wedge cushion or the like.

Finally, FIG. 5 is a headrest or a head cushion with two adjacent indentations 6

shown, the side distance from each other naturally can be changed as required. Such a head cushion can also be those shown in FIGS. 2, 3 and 4 Have features, i.e. a wall piece 9 closing off the indentations 6 can be formed on the rear edge and filler pieces 10 can be provided depending on If necessary to be able to cover one of the two indentations or both at the same time.

The thickness of the head cushion at the location of the indentation 6 and the height of the lateral beads 4 and 5 are dimensioned such that the upper part of the spine of a user average size is held straight when lying on his back or on his side. It is therefore conceivable to industrially manufacture such pillows in different dimensions, i.e. for different body sizes, whereby there would be a profound change in the manufacture and sale of headrests or pillows,

Despite this relatively profound change or modification In the construction of head cushions, the position remains but extremely simple and in no way deviates significantly from the normal way of preparing this required devices and machines and the necessary investments. When producing in single formers, offers the formation of the upper form to achieve the indentation neither technical nor economic difficulties. When however, you want to work according to the extrusion process and later want to cut the extruded part to the desired height or width of the head cushion corresponding lengths, so one becomes. corresponds to the explanations according to FIGS. 1, 3 and 5 serve. On the other hand, can also be in individual forms

produce several head pads at the same time by using a Shape is used, the cross-section of which corresponds to the cross-section of the desired head cushion., Whose length .jedoch equal to a multiple of the width of the one to be produced Head cushion is. Making the solidification of the elastic mass with cellular structure can be the contiguous Easily separate parts into the required number of individual heads upholstery.
