The invention relates to a pillow. Pillows are already known in many shapes and sizes. A disadvantage of known pillows is that they either do not provide a desirable good adaptation to the body shape or accompany the rolling process in sleep, especially in rotational movements, not desirable, or provide in this no desirable large freedom of movement.
The invention has set itself the task of creating a pillow, which is improved at least with regard to one of the disadvantages mentioned.
This object is achieved by the reproduced in claim 1 pillow.
The pillow according to the invention has a shoulder cut. By this is meant an incision which creates a recess which is of such shape and size that it can be at least partially filled by a user's shoulder. In other words, the recess created by the shoulder incision creates a patz for the shoulder and not just for the neck.
As a result, inter alia, a good adaptation of the pad to the body shape can be achieved. The accompaniment of the rolling process during sleep (during a rotation movement of a user) through the cushion is made possible or improved. It allows a free movement of the user through the Schultereinschnitt.
In addition, this can be achieved, inter alia, that the neck always remains free in about the same length both in the back and in the side or prone position, so is not in contact with the pillow while the head is always full on the pillow lies. The shoulder cut is preferably rounded. More preferably, it does not extend over the entire length of the corresponding side of the pad.
Advantageously, the pillow has a thinner side or a thinner region on the edge side and a thicker side or a thicker region on the edge side. The shoulder cut is preferably arranged on the thinner side or in the thinner area on the edge. The shoulder cut is preferably provided on the side of the pillow facing the user when used properly. If, as preferred, the user-facing side is the thinner side of the pad, then a cushion comfortable for many different sleeping positions is provided. Unlike a conceivable cushion, in which the thicker side faces the user, or in which the shoulder incision is provided in the thicker side, the cushion then has no or at least no extreme neck supportive property.
Advantageously, the top of the pad is wavy. The pad preferably has a central area by having its smallest thickness. This can u. a. a moderate neck supportive property can be achieved.
In principle, it is also conceivable that the cushion has a uniform thickness in another embodiment.
Preferably, the shoulder incision is perpendicular. The shoulder cut is thus preferably perpendicular to the underside of the pad. Thus, the shoulder incision preferably is not merely a chamfer or flattening, but the shoulder of a user has completely made available the cross section of the recess over the entire thickness of the cushion created by the shoulder incision.
Advantageously, the pillow has openings. As a result, the air circulation can be increased and the hardness of the pad can be modified.
Advantageously, the openings are arranged exclusively in a circular segment-shaped central region of the pad. It has been shown that this way a special sleeping comfort can be created.
The cross-section of the pad preferably remains constant over the entire width of the pad except for the shoulder incision and any rounded corners and any apertures. Advantageously, therefore, no further flattening, indentations or the like are available. The waveform thus remains preferably the same over the entire width of the pad. This results in a simple manufacturability of the waveform. The wave profile can be introduced, for example, in a foam strand of great length. This must then be separated only in pieces of the correct length (corresponding to the desired width of the pillow).
If the bottom is flat, then there is a particularly good, non-tilt pad on the mattress.
The pad may comprise material or be formed by material comprising gel. The material preferably has viscoelastic Properties on. This material may include polyurethanes in addition to gel. It can be foamed. It can be a homogeneous foam. The foam may have an open cell structure. This can be achieved that the cushion causes a good pressure distribution, good ventilation and good support.
The invention will now be explained with reference to an embodiment shown in the drawings. Show it:
1 a top view of an embodiment of a pillow according to the invention;
2 a page illustration of a pillow as in 1 ;
3 a perspective view of the in 1 shown pillow on a larger scale;
4 a view like in 3 , from a different angle;
5 schematically an exemplary use of a pillow according to the invention.
That as a whole with 100 designated pillow according to the invention shown has a substantially rectangular plan. It is a bed pillow. From the rectangular shape of the floor plan of the pillow gives way to rounded corners 7 . 7 ' and the shoulder cut 1 off ( 1 ). The pillow has a longer straight side 11 , one of this side opposite, through the Schultereinschnitt 1 and rounded corners 7 . 7 ' curved side 12 on and two shorter pages between these pages 13 . 13 ' , The shorter sides 13 . 13 ' stand perpendicular to the longer side 11 , The longer, curved by the shoulder incision side 12 is facing the user when properly used.
2 shows the cushion in a side view with a maximum depth t1. As 2 shows, points the upper side 4 of the pillow on a wavy shape. The top 4 of the pillow rises from the user-facing side 12 with decreasing slope until it reaches a first local maximum in the edge thinner area 2 achieved, wherein the cushion has a first thickness d1.
Subsequently, the top of the pad falls off until it has a minimum in a middle region at which the pad has a smallest thickness d3. From this, the top of the pad rises until a global maximum in the thicker area at the edge 3 is reached, wherein the cushion has a maximum thickness d2 (see. 2 , left to right). The thickness d1 of the edge thinner area 2 is therefore smaller than the thickness d2 of the edge thicker area 3 and greater than the thickness d3 of the central region 6 , The waveform of the top 4 is too 3 good to take. 3 also indicates that the waveform remains the same across the entire width b1 of the pad. The cross section of the pad is therefore across the width b1, except for the shoulder cut 1 and the rounded corners 7 . 7 ' constant.
As 2 shows is the bottom 5 the pad in the embodiment shown flat or plan. The entire bottom 5 lies completely on a flat surface, such as a mattress on.
The shape of the shoulder cut 1 created recess 10 (hatched area in 1 ) is half-spindle-shaped in the embodiment shown. The recess 10 does not extend over the entire width b1 of the pillow. The recess 10 thus has a width b2 which is smaller than the width b1 of the entire pad. The width b2 of the recess is preferably greater than half the width b1 of the pad. In the embodiment shown, the width b2 of the recess extends over approximately 4/5 of the width b1 of the pad. The floor plan of the pillow is symmetrical, with one parallel to the shorter sides 13 . 13 ' extending symmetry axis M. Also the recess 10 is symmetrical to this axis M. It has its greatest depth t3 in the region of this symmetry axis M.
As in particular in 1 to see, the pillow has breakthroughs 8th on. These have a circular or circular segment-shaped cross-section. The breakthroughs 8th are arranged exclusively in a circular segment-shaped central area B. This region has an axis of symmetry which coincides with the symmetry axis M of the pad. The circle segment shape will be on the side 12 facing side of the area B by two straight lines l, l 'limited. These run from the circular arc U of the central region B to the axis of symmetry M. They are not perpendicular to the axis of symmetry M, but are slightly inclined in the direction of the segment center point P. The lines l, l'are tangent to the shoulder incision 1 , The diameter D of the circular portion of the circle segment of the central portion B is slightly smaller than half the width b1 of the pad. It is larger than the minimum depth t2 of the pillow.
5 leaves virtues of the pillow 100 recognize: It adapts well to the body shape. It accompanies the user during the rolling process during sleep, for example during rotary movements. Through the shoulder cut 1 is a free movement of the user possible. The head can always rest completely on the pillow, with a neck area that is always about the same length and free of pillow contact. In 5 in dashed lines is a known from the prior art rectangular cushion 9 indicated without shoulder cut. It can be seen that in this the advantages of the pillow according to the invention are not achieved. The head is not always completely arranged on the pillow and the neck is in the mid-illustrated supine position over a much longer section in contact with the pillow, as in the laterally shown side or prone positions.
