Description

The The invention relates to a pillow, in particular neck support pillow with at least two distributed over the pillow width and thus adjacent supporting areas, of those of a support area of the support of Head in supine position and the other support area the support of the head is in a lateral position, wherein the one support area one opposite the other support areas having increased compliance. Preferably, the invention relates a pillow, z. B. neck support pillow with at least three over the pillow width distributed support areas, of which the middle support area of the support of the head in the supine position and the lateral support areas serve the support of the head in a lateral position, wherein the middle support area one opposite the side Support areas has increased compliance. The thickness of such a neck support pad can over the cushion depth (which in the course of use along the mattress longitudinal direction extends), in particular one or more Neck rolls can be present. About the pillow width However, the thickness is substantially constant in the unloaded state. Pillow width means the direction, which in the course of use extends substantially along the mattress width.

Cervical pillow with different over the pillow width distributed Support areas where the central support area the support of the head in supine position and the lateral support areas of the support of the head serve in a lateral position, are in various embodiments known. The different support areas are supposed to be fact Bear in mind that in the lateral position due to the shoulder width a higher support of the head desired is as in the supine position. For this reason were in The practice used neck support pillows that have an over have the cushion width varying thickness, wherein in the middle of the cushion a smaller thickness is provided to form a "trough". Such an embodiment is often perceived as disadvantageous, since fixed reclining positions for the individual attitudes specified are.

For this reason, neck support cushion of the type described above have already been proposed, which have a substantially constant thickness over the width in the unloaded state and are thus formed without troughs or the like indentations and instead have several distributed over the pillow width support areas of different compliance. In spite of the thickness, which is essentially constant over the width of the pillow, it is achieved that the head can sink lower in the supine position than in the lateral position, so that the head is more strongly supported in the lateral position in relation to the shoulders. In order to achieve this, it has been proposed, for example, that the middle region of the support core of the neck support cushion is made more flexible by at least one lenticular cross section in section (cf. DE 10 2007 059 383 A1 ).

From the DE 20 2007 012 748 U1 Known a neck support cushion with a changing over the cushion depth thickness, on the one hand a support region for the head and on the other hand a support region for the neck is provided in the form of a neck roll. In order to form the support effect of one or both neck rolls in the central transverse region, on which the head rests in the supine position, less than in the two lateral regions, it has been proposed to interrupt a arranged in the neck roll stiffening insert in the middle region or there an insert of softer To store plastic. Optionally, the neck roll may also consist of three sections, which may be joined together by gluing, the middle region of this neck roll being made of foam material of lower compressive strength.

Other embodiments of neck support pillow, which support areas for the supine position on the one hand and support areas for the lateral position on the other hand, for example, from the DE 10 2005 004 033 A1 , of the DE 36 27 286 A1 , of the DE 296 001 71 U1 , of the DE 201 15 917 U1 or the DE 299 00 237 U1 known.

Also if the known neck support cushion of the above-described Kind basically in various embodiments Support areas for on the one hand the supine position and on the other hand provide the lateral position, so they are in part with drawbacks. For one thing the production consuming and therefore be associated with high costs. On the other hand often does not succeed the appropriate adjustment to the desired conditions, in particular for Persons with broad shoulders, which in the lateral support areas expect a significantly higher support effect than in the middle support area. Finally the transitions between the individual support areas often perceived as uncomfortable and disadvantageous. - Here uses the invention.

Of the Invention is based on the object, a pillow and in particular a neck support pillow of the type described above create, which is characterized by a particularly ergonomic design and comfortable use.

To solve this problem, the invention teaches in a generic pillow, z. B. neck support cushion of the type described above, that the individual support areas aneinan at least one abutting surface or at a plurality of abutment surfaces the boundaries, wherein the abutting surfaces to form one or more transition areas with in one direction, for. B. towards the center of the pillow, increasing compliance at a predetermined angle obliquely to the cushion base. Consequently, the neck support cushion is preferably composed of a central support region or cushion part and two lateral support regions or cushion parts arranged on both sides of this central support region or cushion part, wherein the central cushion part has a higher flexibility than the lateral cushion parts. At the transition between the individual areas or cushion parts, however, large differences in the flexibility are now avoided by a smooth transition is realized by the running obliquely to the cushion surface abutment surfaces. While the compliance in the lateral support areas is determined by the low compliance side pad portions, the compliance to the center of the pad increases, as in these transition areas from the pillow edge to the center of the pad, the "thickness proportion" of the center pad portion increases continuously. This configuration means that users can easily switch between the lying positions without disturbing transition areas with strongly varying properties being perceived. The abutment surfaces arranged at an angle to the cushion surface can be planar abutment surfaces, which consequently are substantially or approximately straight in cross-section. In the context of the invention, however, abutment surfaces arranged obliquely to the base of the cushion also include abutment surfaces which are formed in cross-section (regionally) in steps, undulations or the like. Of importance is the fact that varies by the "oblique abutment surfaces" of the respective "thickness proportion" of the two adjacent support areas in these transition areas, z. B. increases or decreases in one direction.

In A first embodiment of the invention is the Possibility that the individual support areas be formed by separately manufactured cushion parts, which on at least one impact surface with each other under education a support core are connected. The individual pillow parts are z. B. as elastic molded body made of plastic trained and connected to each other at the joints. in the As part of the production, therefore, a support core of several Pillow parts assembled, with such a support core then preferably inserted into a cushion cover.

In a modified embodiment of the invention will become several cushion parts or fillings in a cushion cover used with several chambers. In this embodiment the pillow has a cushion cover (eg made of a textile Material), which several by one or more dividers having separate chambers, wherein in the chambers to form the Support areas individual cushion parts of different compliance and / or Fillings of different compliance are arranged, the abutting surfaces of the dividers of the Cushion cover are formed. In such an embodiment First of all there is the possibility of individual To use pad parts, which as in the already described Embodiment as elastic molded body z. B. plastic are formed. In this embodiment However, these individual cushion parts are not now at the joints firmly connected to each other, but the individual pillow parts are used in the individual chambers of the shell, the shape the individual chambers essentially to the shape of the cushion parts is adjusted so that the cushion parts as accurate as possible are fitted in the shell. In a modified embodiment consists in a cushion cover with several chambers the Possibility, as fillings loosely poured synthetic fibers, Natural fibers, feathers, down or the like filling material to use. The different flexibility of the individual Pillow areas can then be set by using different Fillers in the individual chambers or in particular also realize by different fill levels. in principle There is also the possibility of the described embodiments For example, in the outer support areas elastic Shaped bodies are used while in the middle Supporting area used a loose poured filling becomes. Loosely poured thinks that the fibers or the like before filling not in the form of a shaped body, but be present as pourable material, the Fill or fill then depending on the degree of filling strongly compressed in the cushion cover and more or less can be "fixed".

at the embodiment described above with a support core, which consists of several firmly connected pad parts beats the invention in a preferred embodiment that the individual Cushion parts at the joint or at the joints cohesively and / or positively with each other are connected. Cohesively connected means in the frame the invention in particular adhesively bonded, z. B glued. Interlocking connected means in the context of the invention, in particular a plug connection, wherein the individual cushion parts, for example, corresponding form-fitting elements (For example, groove / spring elements) may have.

The individual cushion parts, z. B. the side cushion parts and / or the middle cushion part may preferably have a trapezoidal cross-section. This is especially true for pillow parts, wel che are formed as elastic molded body.

In a preferred embodiment proposes the Invention thereby, that the angle of the impact surface relative to the pad base in about 20 ° to 70 °, z. B. 30 ° to 60 °, more preferably 40 ° to 50 °. Cushion floor area means while the bottom surface during use, which forms the contact surface with the mattress. As explained, the oblique abutment does not have to be exact they can also be wavy, step-shaped or the like run.

While the thickness of the pad changes over the pad depth can, for example, provided one or two bolsters the invention is particularly preferred, that the thickness of the pillow over the entire pillow width is substantially constant in the unloaded state. Pillows, which a thickness that changes over the depth of the pillow with z. B. have one or more bolsters are in the practice referred to as neck support pillow. The invention but also includes embodiments in which the Thickness over the cushion depth is constant and which consequently is waived on neck rolls or the like. Also these pillows are referred to in the context of the invention as neck support pillow.

The Invention basically comprises embodiments, in which the central cushion part, which z. B. as elastic Molded body is made of the same material is like the side cushion parts. The different flexibility is then z. B. by the geometry and in particular the cross-sectional design realized the individual cushion parts. So it may be appropriate in this case be, the middle cushion part as (strong) compliant hollow chamber part to design with one or more cavities. The different compliance can - if for all pillow parts worked with the same material becomes - also by selection of cushion parts different Compression hardness (with the same material) can be achieved.

Especially However, the side cushion parts are preferably from another Material manufactured, as the central pillow part. By suitable Material choice, the desired compliance can be achieved. Also in embodiments with different materials from side parts on the one hand and middle part on the other hand it can be expedient to increase the compliance the middle part of the Mitteilteil as hollow chamber part in the manner described embody.

The middle cushion part may for example be made of (elastic) foam, z. As cold foam or viscoelastic foam, be made. The lateral ones Cushion parts can also be made of (elastic) foam, z. As cold foam or viscoelastic foam, be made. In an alternative embodiment, the lateral Cushion parts also be made of latex. Alternative or supplementary can also be the middle cushion part made of latex. The invention but also includes embodiments with moldings made of other material, preferably plastic.

Provided for the middle cushion part a hollow chamber part with at least a cavity is used, it may be appropriate be when in the middle cushion part a plurality of cavities are provided which are separated from each other at least by a web are. Through an appropriate design and vote of Cavities on the one hand and supporting webs on the other the desired flexibility can be set.

All in all can in the context of the invention by tuning the cushion thickness on the one hand and the complacency of each area on the other hand one optimal adaptation to the desired conditions. In this adaptation, especially the physique of the User and in particular the shoulder width considered. About that but also plays the design of the mattress and in particular their hardness a special role. For users with large Shoulder width usually needs the yielding in the lateral Protection areas particularly strong on the resilience of the middle Support area vary.

consequently becomes a pillow or neck support pillow with optimal support behavior created in lateral position as well as supine. It can an optimal adaptation done, which on the one hand the physique the user and in particular the shoulder width and the other takes into account the strength of the existing mattress. Particularly preferred may be several neck support pillow of the be combined to a pillow set described type, the individual neck support pillow of such a set different Support properties. By appropriate selection can then the described conditions (physique on the one hand and mattress property on the other hand). A further adaptation can in particular by the use of one or more insert plates done. Because with such a Neck support pillow is usually the support core inserted into a cushion cover, preferably one (lower) Insert plates can be introduced into the shell.

In the following, the invention will be described with reference to an exemplary embodiment Drawing explained in more detail. Show it

1 an inventive neck support cushion in a simplified perspective view,

2 a plan view of a support core of the pad behind 1 .

3 a section yy through the support core after 2 .

4 a section xx through the support core 2 .

5 a section through a modified embodiment of a neck support pad.

In the 1 to 4 a first embodiment of a neck support pillow is shown, which in its basic structure a support core 1 which, if necessary, together with a support plate or insert plate 2 in a reference or a shell 3 is used. The neck support pillow and its support core 1 have over the cushion depth T a different thickness. So are in particular two neck rolls 5a . 5b , as well as in between an area with wave cuts 4 intended. The neck rolls 5a respectively. 5b may vary in severity and consequently have a different thickness. Consequently, while the thickness D varies along the cushion depth T, the neck support cushion or its support core (in the unloaded state) has a substantially constant thickness D over the entire cushion width B.

In spite of this constant thickness D over the entire pillow width B are over in the neck support cushion according to the invention the pillow width B spreads three support areas, of which the middle support area M of the support of the Head in supine position and the lateral support areas S serve to support the head in a lateral position. For this purpose points the middle support area M one opposite the two lateral support areas S increased compliance on.

Conversely, consequently, the two lateral support areas S have a reduced compliance compared to the central support area M. The head of a user may thus sink more deeply into the cushion in the middle area, and consequently in the supine position, than in the lateral areas which serve to support the head in a lateral position. The support core 1 consists of individual, separately manufactured cushion parts 6 . 7 together, which at abutting surfaces 8th with each other to form the support core 1 are connected. The middle cushion part 6 forms the middle support area M, while the side cushion parts 7 the lateral support areas S form. At the abutment surfaces 8th the individual cushion parts are preferably glued together.

From a comparative analysis of the 1 to 3 it now turns out that these abutment surfaces 8th at a predetermined angle α obliquely to the cushion base F. This means that transition areas b are formed by these ramp-like abutment surfaces, which have a yielding towards the center of the cushion. Consequently, it is not only achieved that the head in the center of the pad can sink more into the pad than in the marginal areas, but the transition between these individual areas is continuously formed, so that the user does not perceive any large fluctuations in the flexibility when changing the position , The position change from the lateral position to the supine position is thus simplified and annoying transitions are avoided.

In the exemplary embodiment, the angle α in about 40 ° to 50 °, z. B. about 45 °. It can be seen that both the lateral cushion parts 7 as well as the middle cushion part 6 have a substantially trapezoidal cross-section. That means the width of a cushion part 6 . 7 deviates in the upper region of the width of the cushion part in the lower region and is therefore larger or smaller. For example, in the case of 3 illustrated embodiment, that the lateral cushion parts 7 in the illustrated position in the upper region have a smaller width than in the lower region, while the middle cushion part 6 has a greater width in the upper area than in the lower area. However, the pillow can also be used in the reverse position, so that then reverse conditions exist. However, the flowing or ramp-like transitions are always created.

The increased compliance of the middle section 6 can basically be achieved by a suitable choice of material. Alternatively or additionally, however, it may be expedient, the flexibility in the middle part 6 thereby increasing that middle section 6 as a hollow chamber part with at least one cavity 9 is trained. In the embodiment, two cavities 9 provided by a bridge 10 are separated from each other, which runs along the width of the pillow (see. 4 ). By appropriate adaptation of the size of the cavities, the number and strength of the webs and the material thickness in the region of such a hollow chamber part, the desired flexibility can be adjusted. In the preferred embodiment according to 1 to 4 was omitted in the area of the side parts on hollow chambers. However, this does not exclude that the material with "small cavities" in the sense of pores or holes, like these for example, in 1 are indicated, is provided.

While the 1 to 4 show a first embodiment of a neck support pad in which the support core is composed of a plurality of elastic moldings, shows 5 a modified embodiment of a neck support pad, which is a cushion cover 3 ' which has several through dividers 8th having separate chambers, wherein the abutting surfaces 8th between the support areas M, S of these arranged obliquely to the cushion base dividers 8th be formed. In the chambers are to form the individual support areas M, S fillings 6 ' . 7 ' arranged in different compliance. The fillings 6 ' . 7 ' thus consist of poured synthetic fibers, natural fibers, feathers, down or the like filling material. In 5 it is indicated that the middle filling 6 ' is designed by suitable choice of material and / or suitable degree of filling such that an increased flexibility is realized. Also in this embodiment, the ramp-like transition regions according to the invention are realized. In that regard, according to the 1 to 4 directed. This in 5 Cushion shown can also be used in principle in another separate cushion cover, as in accordance with the support core 1 to 4 is shown. Incidentally, it may be appropriate to dispense with such a pillow with poured fillings on (pronounced) neck rolls. Thus, in such an embodiment, the thickness across the pad depth may be substantially constant. This is not shown in the figures. Such an embodiment with poured filling and / or constant thickness over the pad depth is referred to in the context of the invention as a neck support pillow, since it also has individual support areas for on the one hand the supine position and the other side position.
