Description

1. Technical field of the invention

The present invention relates to blankets, in particular blankets for beds, sleeping bags, animal blankets, travel, living or bedspreads, as well as pillows and garments.

2. Background of the invention

Currently, blankets are known in the art, e.g. characterized by a shell of finely woven cotton material, which are filled with feathers and / or down. Also known are blankets in which balls made of plastic fibers or short staple plastic fibers with a length of 8 to 24 mm, so-called blown fibers, are used as filler material. Moreover, there are so-called quilted beds in which a more or less voluminous nonwoven layer is quilted as a filling with outer fabric layers. In addition, particularly in southern countries, simple blankets wrapped in sheets, e.g. of wool, used as cover.

Common to all these cover variants are a uniform and continuous outer cover or outer boundary surfaces.

This basic design principle was first introduced by the ClimaBalance product range EP 1 499 221 breached. This innovative Zudeckenkonzept is characterized by the presence of several ventilation openings, which are each covered by grid mesh defined air permeability. Again, however, it is a continuous and continuous, albeit interrupted by ventilation openings, position of a flexible insulating material.

This feature of known designs of blankets comprising a continuous layer of flexible insulating material results in the blanket being only partially able to adapt to the body contours of the person sleeping underneath. Incidentally, the required to achieve a specific insulation effect capacity is unsatisfactory high. Furthermore, the appearance of the covers of the prior art is uniformly discreet and at best determined by the geometric arrangement of the quilting seams or webs. Apart from the ClimaBalance ceilings mentioned above, there is no satisfactory dissipation of heat and moisture generated by the body in the prior art blankets.

In view of the prior art discussed above, it is an object of the present invention to provide a blanket which has improved conformability, e.g. allowed to the body contours of a sleeper underneath. Furthermore, the present invention is based on the object to provide a blanket, which ensures satisfactory heat and moisture removal and thus creates an air conditioning of the bed cavity. The advantages of the ceiling to be provided should come into play especially when used in warm summery climatic conditions. Moreover, the object of the present invention is to provide a blanket which is distinguished by a clearly different appearance from the prior art. The ceiling to be provided should continue to be characterized by ease of manufacture and handling. Another object of the present invention is to provide a blanket which offers advantages in practical use when used in hospitals. Finally, it is the object of the present invention to provide all the advantageous properties described in this section in the same way, without associated disadvantages in handling or cleaning.

Furthermore, the present invention relates to the provision of cushions, sleeping bags and garments, which are based on the design principle according to the invention and also have the above-mentioned advantageous features according to the invention (contour adjustment, reduction of the filling weight, air conditioning and attractive visual appearance).

Another object of the present invention is to provide processes for the preparation of the above-mentioned products.

3. Summary of the invention

The above-mentioned objects are achieved according to the invention by the blanket according to the following claim 1, wherein the continuous surface of conventional blankets is constituted by the presence of a group of separate, parallel strips fixed but not continuous with the adjacent strips.

Preferred embodiments of this blanket according to the invention are described in the following claims 2 to 13.

Moreover, the present invention relates to sleeping bags and garments, as well as pillows, preferably pillows, Duodecken and four-season covers, all based on the principle of the invention. Such products are described in the following claim 1.4.

Furthermore, the present invention relates to processes for the preparation of the abovementioned products according to the following claim 15.

5. Detailed description of the invention 5.1 Definitions

In the context of the present invention, the term "down-proof" means that the covering material in question for the filling material to be used has the properties to be fulfilled according to the standard EN 12132-2 (Stumpp test).

In the context of the present invention, the term "fiber-tight" means that the respective shell material for the filler material to be used has the properties to be fulfilled according to the standard EN 12132-2 (Stumpp test).

By "hull" is meant a textile material enveloping a filling that is directly or indirectly in contact with the filling, e.g. Down is.

For the purposes of the invention, a "blanket" is understood to be any product suitable for covering or wrapping human, animal or material, with blankets for humans representing a preferred embodiment.

"Open textile fabrics" are understood as meaning textile fabrics which have a high air permeability of typically 200 l / dm ² min (measured at a pressure gradient of 200 Pa) - 1000 l / dm ² min (measured at a pressure gradient of 13 Pa) 250 l / dm ² min (at 200 Pa) - 800 l / dm ² min (at 13 Pa), and more preferably 300 l / dm ² min (at 200 Pa) - 600 l / dm ² min (at 13 Pa) even more preferably 800 l / dm ² min (at 200 Pa) - 100 l / dm ² min (at 13 Pa). Such an open textile fabric may be in the form of a coarse fabric, but it may also consist of a fabric, knitted fabric, foil or the like in a perforated flat material. These are typically textiles, especially in the field of knitted fabrics, such as perforated knitted fabrics, in particular polyester-hole-fillet knits, or charmeuse fabrics, such as rhombus sleeves or hole charmeuse. Also in the field of fabrics is about gauze or mesh fabric as a suitable open textile fabric. Furthermore, textile open fabrics such as nonwovens, in particular thermobonded spunbonded nonwovens, possibly with punched holes or fibers in biaxial or multiaxial layers, such as are also used as reinforcing material in fiber-reinforced plastics, come into consideration. Advantageous examples of open textile fabrics are in the plan view or review, in particular with a proportion of To observe openings such as holes, pores, free mesh and the like. From 10 to 40%, preferably 15% to 30%.

As "substantially equidistant arrangement of the adjacent side edges" arrangements are understood in which the respective adjacent side edges have a constant distance from each other, which varies by 0 to 5 cm, preferably 0 to 1 cm.

By "permanent fixations" is meant fixations that are merely irreversible, i. under destruction of fixation, can be solved from each other. Examples include desertions and stitching.

5.2 Construction of the ceiling First embodiment

The blanket (1) of the first embodiment according to the invention is characterized by a construction in which two or more strips (2.1, 2.2, 2.3, 2.4 and 2.5) are juxtaposed with the adjacent side edges being substantially equidistant and with the strips being relatively square are permanently fixed to the respective adjacent strips. The parallel strips may be arranged along the length or width direction of the ceiling. Even a diagonal arrangement is conceivable. The arrangement along the length direction of the ceiling is preferred.

An essential feature of the invention is that the non-releasable fixings (3) do not connect the adjacent strips continuously over their entire length. Rather, adjacent strips are interconnected by two or more discrete, separate fixings. It is preferred that between the adjacent fixings spacings (4) are in the range of 1 to 50 cm, more preferably in the range of 5 to 20 cm, most preferably from 8 to 16 cm.

The non-releasable fixations, for their part, occupy a relatively small space, typically in the range of 0.001 to 10 cm, preferably 0.01 to 5 cm, along the strips to be fixed (this statement refers to individual fixations in each case).

Said fixation can be done by sewing or quilting the strips. Preference is given to circular desertings with a diameter of 1 to 4 cm, preferably 1.5 to 3.5 cm in diameter, the center of which is preferably located exactly between the two strips. Also conceivable are square, rectangular, diamond-shaped or linear embroidery. The permanent fixation preferably by sewing or quilting has the advantage of particularly simple construction, simple and inexpensive production and ease of use. According to a preferred embodiment, the fixation differs in material and manufacture from the surrounding strips.

In each case adjacent strips can be fixed to one another with a distance of 0 to 5 cm, preferably 0 to 2 cm. They may also, according to the following second embodiment, be fixed to each other so that there is no distance between the strips. Furthermore, adjacent stripes may also overlap slightly (i.e., 0 to 3 cm, preferably 0 to 1.5 cm).

Permanent openings (4) are present between the fixings when the strips are fixed at a distance from each other. Moreover, regardless of the distance of the adjacent strips between the adjacent strips, openings are caused by a curvature of the ceiling surface, as is typically caused by the covering of a human body. The openings caused by such a curvature can be spanned by open textile fabrics one or more layers.

The open construction of the blanket according to the invention allows an improved air exchange between bed cavity and outside space compared to conventional blankets and thus an improvement of the microclimate within the bed cavity. It also allows for improved adaptability to the body contours of the underlying person.

It is also possible two ceilings according to the invention according to the principle of Duodecken or four-season ceilings inextricably or releasably connect with each other. In these embodiments, the individual strips of the two layers can be congruent to one another or offset from one another. The latter arrangement slows the exchange of air and is therefore particularly suitable for winter blankets.

The number of strips per blanket is not specified and is determined by the format of the blanket and the strip widths given later.

According to further variants of the present invention, areas formed from strips can be combined with conventional ceiling areas. Said ceiling areas of conventional type can be filled or unfilled conventional ceilings. A typical variant of this is a strip construction surrounded by a continuous conventional frame. Similarly, a plurality of such woven strip portions (1.1, 1.2) can be incorporated into a conventional blanket (8). In particular, ceilings with 2 to 20, preferably 2, 3, 4, 5, 6, 7 and 8 of such areas and in particular ceilings with 2, 3, and 4 such strip areas are contemplated as being suitable according to the invention. The areas may have any shapes, with rectangles and diamonds being preferred. In this variant, both filled and unfilled strips and combinations thereof can be used.

A further aspect of the present invention relates to the possibility of using different filling and / or wrapping materials and / or filling weights and / or strip widths for different strips or strip groups. Thus, for example, it is conceivable to provide a group of down filled strips that are combined with a second nonwoven-based quilt-like strip group. The stripes of the different groups may either be arranged alternately in parallel (stripe sequence -A-B-A-B-etc.) Or they may be grouped into arbitrary blocks (stripe -A-A-A-A-B-B-B-B. -A-A-B-B-A-A-B-B, etc.). A preferred variant relates, for example, ceilings in which the strips in the central region are narrower than in the two edge regions. Other typical combination possibilities include the combination of a filled strip group with a second group of unfilled strips, for example strips of wool fabric. Furthermore, in the context of the present invention, it is also possible to emphasize even more strongly the appearance of the ceiling according to the invention which is anyway unusual and interesting due to the open structure by using differently colored strips.

Second embodiment

The ceilings (1) of the second embodiment correspond in their construction and the materials used the blankets of the first embodiment, unless otherwise described below.

An essential aspect of the second embodiment is that adjacent strips (2.1, 2.2, 2.3, 2.4 and 2.5) are in contact with each other such that only their mutually facing side edges touch (5). Openings are created between the adjacent ones Strips only by a curvature of the ceiling surface, as it is typically caused by the covering of a human body. The openings caused by such a curvature can be spanned by open textile fabrics (6, 7) in one or more layers.

Strips are fixed according to the invention to the adjacent strips. These fixations are not continuous but, as described in the first embodiment, occupy only a small portion of the total length of the strips. The fixation of the adjacent strips can be done detachably or permanently. Each strip should be connected to the rest of the blanket via at least two fixings. Practically, it is advisable to fix each strip at least at its ends with the adjacent.

However, it should be avoided to consider too intensive fixation of the respective strips to ensure a minimum of suitability for opening the strip spaces by means of curvature of the ceiling surface. Incidentally, the fixing distances described in the first embodiment are applicable.

Such a partial fixation of the strips to one another makes it possible to emphasize to a particular extent the suitability of the invention for adaptation to the body contours of the sleeping person.

Said fixation can be done inextricably by sewing or quilting the strips. Also conceivable, however, is a releasable fixation by means of Velcro fasteners, press studs, double mushroom buttons, etc. If a releasable fixation with Velcro closures, etc. is selected, the blanket offers the particular advantage of the separate washability of the individual strips by the end user. According to a preferred embodiment, the fixation differs in material and manufacture from the surrounding strips.

As already mentioned, when choosing suitable fixing points and their density it is essential to pay attention to good adaptability to the body contours.

Some of the above-described embodiments of the present invention relate to ceiling structures in which the strips can be at least partially detached from the end user and later reconnected and fixed together. These embodiments have the advantage of renewing individual strips or against alternative strips with different insulation effects, colors, etc., can be replaced. It is within the scope of the present invention possible and contemplated that the end user can put together a blanket as needed and personal preferences. For example, it is conceivable to assemble a blanket in which particularly high insulation effect is achieved in the foot area as well as in the area of the fuselage, but not in the other areas.

In any of the above-described embodiments and variants thereof, it is advantageous to fix the inherently loose strips along the outer edge of the blanket.

The format of the blanket according to the invention is not fixed. Typical embodiments are blankets with the usual dimensions of blankets: 135x200 cm and 155x220 cm but also foreign dimensions of e.g. 220x260 cm.

An introduction of the blankets according to the invention in continuous casings is possible.

5.3 strips

The strips to be used according to the invention can be filled casings for both the first and second embodiments described above, or also unfilled strips of a flexible textile fabric.

The shape of the strips is typically rectangular. The following statements relate in particular to such rectangular strips. However, it is also conceivable to use strips which have a geometry deviating from the rectangular shape. Conceivable, for example, trapezoidal, wave or (semi) circular stripes. Even "stripes" that do not have a typical strip length to width ratio of at least 2: 1 can be used. Here are, for example, square or circular stripes to call. Finally, the strips can also have any irregular shapes such as heart shape, cloverleaf, and the like. In all cases in which the individual strips can not be combined to form a continuous surface (eg heart shape as opposed to rectangular or square strips), the respective shapes are supplemented by one or more strips with a complementary "negative shape", which the Forming a continuous area allowed.

The length of the strips is typically adjusted to the length of the surface to be spanned (that is, either the length of the blanket or the length of the respective strip area within the blanket).

The width of the stripes is not specified. The strips to be used according to the present invention typically have a width of 2 to 80 cm, with ranges of 5 to 70 cm, in particular of 10 to 60 cm being preferred. More preferred are strips of a width of 10 to 35 cm, and most preferably strips of a width of 15 to 30 cm. In the inventive design of a ceiling with 6 parallel strips arranged for the current standard ceiling dimensions results in an ideal strip width of about 22 to 23 cm for blankets in the normal format (135 * 200 cm) and a preferred range of 25 to 26 for the strip width of oversized blankets (155 * 220 cm).

It is also conceivable that the width of a strip changes along its length, for example a blanket with longitudinal strips with wider strips in the trunk area compared to the leg area. Through the resulting local overwidth, the ceiling provides a shape in the third dimension, out of the area in the height, so as to preform the varying body shape of the sleeping.

The trapezoidal or wavy stripes conform to those of the rectangular stripes.

Square stripes typically have an edge length of 15 to 80 cm, more preferably 20 to 50 cm. The diameters of circular stripes are typically in the range of 15 to 50 cm, preferably 20 to 40 cm. The same applies to the maximum diameter of irregularly shaped strips (e.g., heart or cloverleaf).

The individual strips can also be equipped with one or more climatic zones according to EP 1 499 221 be provided.

According to the present invention, it is likewise conceivable to use different strips or strip groups which differ, for example, from one another in the respective width. For example, it is preferable to use wider strips in the edge regions of the ceiling, ie the outermost strips in the top and bottom area or on the left and right edges. For ceilings in which the strips are arranged transversely, the strip widths of the heat release of the body parts can be adjusted, ie wider stripes in the foot area (low heat emission), narrower stripes in the torso area (greater heat dissipation), as well as one or two wider stripes in the head area.

5.4 strip cover

Subsequent embodiments apply to both the first and the second embodiment described above. According to a typical embodiment of the present invention, strips are used, which consist of a shell of upper and lower plate of a flexible material. This may be a casing of a finely woven fiber and down-dense cotton fabric (so-called inletted fabric), which may be a conventional filling e.g. can absorb from down and / or feathers. Depending on the type of filling, the material used for the shell can be varied. For fleece fillings, as is typical for quilts, it is not necessary, for example, that the sheath material is down-proof.

In principle, all wrapping materials in all available colors are conceivable. Also combinations of different colors in different stripes are possible.

The material of the shell may also be cashmere fibers according to DE Note 10 2007 001 433.5 or kapok fibers according to DE Note 10 2007 010 851.8 contain. Of course, the use of suitable synthetic fibers in the context of the present invention is conceivable.

It can also knitted fabrics and spunbonded fabrics are used. These are made of natural and / or synthetic fibers and filaments. A preferred natural fiber is cotton. The synthetic fibers and filaments are preferably selected from polyesters, for example polyethylene terephthalate (PET), polyolefins such as polypropylene (PP), polyamides, for example Cordura or polyaramids such as Kevlar®, Nomex®, or mixtures thereof. Also, the use of fibers containing ceramic material is possible within the scope of the invention. A suitable fiber is, for example, the Trevira Bioactive® fiber. Alternatively, it is possible to use filament fabrics, for example nonwovens or microfiber webs, for example Evolon® from Freudenberg Evolon KG, as described in US Pat DE 20 310 279 U1 and WO 01/47383 A1 are described. These microfiber nonwovens are not only distinguished by their air and vapor permeability but also by their mite allergen-retaining properties. Mixtures of the materials mentioned can also be used in the context of the present invention.

In the context of the present invention, it is further preferred to divide the strip casings into individual chambers in order to better fix the contents over the strip length or width. In this case, all conventional embodiments are possible, in particular, a direct connection of the upper and lower plate of the shell is possible, or the incorporation of partitions, the so-called. Webs, between the upper and lower plate of the shell. When filling with bulk materials such as down, feathers, fiberballs, blown fibers, etc., filling openings are to be provided at the junctions of the top and bottom plates.

Of course, according to the present invention, it is also conceivable to use different groups of strips which differ from one another by the shell material used.

5.5 strip filling

Subsequent embodiments apply to both the first and the second embodiment described above. The individual strips can be provided with all filling materials used for conventional ceilings. Again, there are no restrictions. Preference is given to fillings made of feathers, down, natural fibers and animal hair such as kapok fibers or wool, synthetic fibers such as fiberballs and nonwovens and latex, for example natural rubber. Suitable synthetic fibers may consist of polyester and / or polyamide. Also hollow fibers can be used advantageously in the context of the present invention. Furthermore, foam can be used as filler. Here, in particular so-called polyurethane sticks (ie small rods of polyurethane with typically a length of 9 to 40 mm (preferably 18 to 20 mm) in length and a cross section of typically (4 to 12 mm) x (2 to 6 mm), are preferred (7 to 9 mm) x (3 to 5 mm), which are hereinafter referred to as "PU sticks"), or to call foam balls. Preferred foam materials are polyether urethane, polyester urethane and foams of viscoelastic rubbers, etc. The densities of the preferred foams are in the range of 15 to 55 kg / m ³ , with PU sticks preferably made of materials with a density of 18 to 24 kg / m ³ are. The compression hardnesses of the materials are preferably 1.0 to 5.0 kPa, measured according to DIN 53577. For PU sticks, materials with compression hardnesses of 1.0 to 2.0 kPa are preferred. Another one suitable filling material are foam structural plates. Preference is given to foam structural panels with small segment sizes in the range of 5-50 cm, more preferably 10-35 cm, particularly preferably 10-20 cm in each dimension. Also suitable as the wrapping material are gels which are in the form of gel cushions or gel structure plates (eg honeycomb structure). Also possible are combinations of foam structural plates and gel structure plates. As filling also natural materials such as spelled grains and cherry pits can be used.

In the context of the present invention, it is also possible to combine strips with different filling weights and / or different filling materials.

Thus, it is conceivable and preferred to simulate the body zone structure of the sleeper by the strip widths and / or the shape of the strips and / or the filling of the strips. For example, it is advisable to equip the foot area with a higher filling quantity per unit area compared to the trunk area.

5.6 Unfilled stripes

Subsequent embodiments apply to both the first and the second embodiment described above. In addition to the filled strips described above, it is further possible within the scope of the present invention to provide one or more strips or groups of strips consisting only of an unfilled material. This can typically be a textile fabric such as a woven fabric, knitted fabric, nonwoven fabric, open fabrics, Charmeuseware, bi- or multi-axial fabric. Typical examples of these fabrics are woven and knitted and optionally additionally roughened woolen fabrics, eg of cashmere wool, woven or knitted cotton fabrics, woven or knitted and additionally roughened cotton fabrics, perforated knitted fabrics, in particular of polyester, fleece material, Rautencharmeuse or Lochcharmeuse, gauze, volume nonwovens eg used for the filling of commercially available quilts, thermobonded spunbonded fabrics, possibly with cutouts, fabrics made of polyacrylonitrile fibers (PAN) and others. It is also possible to use mixtures of these materials, for example mixtures of PAN and cotton. There are no fundamental restrictions; all materials can be used _; as typically used for wool blankets, blankets or spa blankets. Rather, the strip material to be used in terms of suppleness, insulation properties, suitability for moisture removal, price, Equipment variants, features, etc. can be selected as needed. A use of unfilled strips is particularly suitable in combination with another group of strips, which is formed from strips provided with a filling.

5.7 Manufacturing process

The blankets according to the invention can be produced as follows, wherein the described production methods for the production of blankets of the first and second embodiment are equally suitable: In the case of the use of filled strips, there are two alternative production methods, which are characterized below by method a and method b :

• a1. Vorlegen einer gewünschten Anzahl von Streifenhüllen;
• a2. Befüllen der Streifenhüllen mit dem gewünschten Füllstoff_;
• a3. Positionieren der Streifen zueinander in der gewünschten räumlichen Anordnung; und
• a4. Fixieren der Streifen untereinander.

In accordance with method a , first the individual strips are filled, then brought into the desired spatial orientation relative to one another, for example by laying the already filled strips. In a final step, the groups of strips are fixed relative to one another, for example by sewing, stitching together or quilting. The method steps of method a can thus be characterized as follows:

• a1. Presenting a desired number of strip sleeves;
• a2. Filling the strip casings with the desired filler _;
• a3. Positioning the strips to each other in the desired spatial arrangement; and
• a4. Fix the strips with each other.

• b1. Vorlegen einer gewünschten Anzahl von Streifenhüllen;
• b2. Positionieren der Streifenhüllen relativ zueinander in der gewünschten räumlichen Anordnung;
• b3. Befüllen der Streifenhüllen mit dem gewünschten Füllmaterial,
• b4. Fixieren der Streifen untereinander.

Method b is characterized by a partially inverted sequence of the method steps. Here, in a first step, the spatial orientation of the strip casings is first produced relative to one another, and only then is the filling introduced into the individual strips. According to two alternative procedures, the fixation of the strips can be done before or after filling. The method steps of method b can thus be summarized as follows:

• b1. Presenting a desired number of strip sleeves;
• b2. Positioning the strip covers relative to one another in the desired spatial arrangement;
• b3. Filling the strip casings with the desired filling material,
• b4. Fix the strips with each other.

• b1. Vorlegen einer gewünschten Anzahl von Streifenhüllen;
• b2. Positionieren der Streifenhüllen relativ zueinander in der gewünschten räumlichen Anordnung;
• b3'. Fixieren der Streifen untereinander.
• b4'. Befüllen der Streifenhüllen mit dem gewünschten Füllmaterial;

An alternative to the above procedure is the following process variant:

• b1. Presenting a desired number of strip sleeves;
• b2. Positioning the strip covers relative to one another in the desired spatial arrangement;
• b3 '. Fix the strips with each other.
• b4 '. Filling the strip casings with the desired filling material;

This alternative process variant is preferred.

• c1. Vorlegen einer gewünschten Anzahl von Streifen;
• c2. Positionieren der Streifen zueinander in der gewünschten räumlichen Anordnung; und
• c3. Fixieren der Streifen untereinander.

Unless unfilled strips are used for this falls of course, the step of filling away. In this case, the following procedure results. Also in the case of quilts-like stripes and / or blankets, the following method c is preferred.

• c1. Presenting a desired number of stripes;
• c2. Positioning the strips to each other in the desired spatial arrangement; and
• c3. Fix the strips with each other.

When using quilts-like strips in combination with alternative filled strips, the method c can be suitably combined with any of the above methods a and b, for example by the sequence (b1) - (c1) - (b2 or c2) - (b3 'or c3) - (b4').

5.8 Equipment

Subsequent embodiments apply to both the first and the second embodiment described above. The strips to be used according to the invention can be provided with any desired features, which are also conventional Ceilings are used. There are no restrictions in this regard. For example, it is conceivable to equip the strips with ceramic-containing fibers, simtex fibers (metal-containing fibers or metal-coated fibers) or carbon fibers. Also, the wrapper can be coated with small ceramic particles, as in DE Note 10 2006 017 338.4 described. Furthermore, the strips can be equipped with measuring probes. You can also be provided with a heat grid. It is also possible to equip it with antibacterial substances, flavorings, phase change materials, materials for dissipating electromagnetic oscillations, optical fibers as lighting and functional elements and, of course, the provision of optical ornaments.

5.9 Applications

Subsequent embodiments apply to both the first and the second embodiment described above. An advantage of the blankets according to the invention is the fact that, due to the bulbous structure of the filled strips and the absence of filling material in the region of the strip spaces, the blankets have a low filling weight in relation to the achieved insulation effect. Thus, the present blankets allow a reduction in ceiling weight and / or an improvement in the insulation effect, as needed. Despite the high insulating effect, the bed honeymoon does not develop into a sweaty, clammy feeling as the ceilings allow an exchange of air and moisture between the bed cavity and the exterior due to their open structure. To emphasize is still the excellent adaptation of the ceiling to the body contours of the sleeping. This property is achieved by the even in the deformed state biegespannungsfreie construction of the ceiling. A plate-plate stitching of the strips can even amplify this effect.

The most important practical application of the blankets according to the invention lies in the area of blankets for beds, in particular in the area of summer blankets, lightweight blankets, eg for waterbeds or air-conditioned rooms. This applies on the one hand to the private end user, on the other hand, however, the object area, such as the use of ceilings in hotels and hospitals, especially in hospitals, the open construction of the ceiling according to the invention may be advantageous because the ceiling according to the invention does not form a closed surface as conventional ceilings, but there are openings between the individual strips through which easily infusion hoses or the like can be guided.

Further applications of the blanket according to the invention are in the residential and wellness sector, e.g. as a blanket on the sofa. In this application, in particular the striking and attractive appearance of the blanket according to the invention is advantageous.

Further applications of the blanket according to the invention lie in the covering of other objects and / or living beings, in particular in cases where good contour adaptation and / or respiratory activity are important. Typical examples of these applications are the covering of furniture and / or horse blankets.

Furthermore, the blankets according to the invention can also be processed or used as sleeping bags. The sleeping bags according to the invention are suitable for use in sports, camping and / or travel. They can be provided for both outdoor and indoor use, with the latter being preferred. The construction according to the invention strip-based leads straight to sleeping bags to pronounced advantages in use: Both the better contour adjustment and the improved ability to dissipate excess body heat and moisture especially in the body of the sleeper completely enveloping sleeping bag to a particularly high comfort. The reduction of the required capacity also allows the transport weight of the sleeping bag and reduce packaging volume. Preferably, it is only the top (sleeping cover side) of the sleeping bag according to the invention form.

Another application of the inventive concept is the production of garments from filled or unfilled groups of strips. Particularly preferred are garments with filled strips or with a combination of filled and unfilled strips. For example, it is conceivable to manufacture a down jacket or a down coat from interconnected down-filled strips. Another variant of this embodiment of the invention relates to garments with strips which are filled with polyester nonwovens, blown fibers or Faserkugein. Strip shape, arrangement and fixation of the strips corresponds to the above-described features of the ceiling embodiment. The strip widths and the distances of the fixings are adapted to the changed size proportions adequately, preferably linearly scaled.

5.10 pillows

Another particularly important application of the present invention relates to the use in cushions. Basically, the same design principles, materials to be used and processing steps are applicable here, as described above in connection with the ceilings according to the invention. Of course, this pillow-specific peculiarities come into play, which may require adjustments. For example, the format of the pillows is less than that of the blankets according to the invention. Typical pillow formats are 40x40 cm, 40x80 cm, 80x80 cm and other dimensions.

Even with the fillers certain cushion-specific adjustments can be made. Compared to ceilings, it can be filled with voluminous and / or stiffer filling materials in order to achieve an increased cushioning effect. All fillers and materials used in conventional cushions can be used in the context of the present invention, in particular down, feathers, fiber beads, microfibers, spelled and cherry cores and PU sticks and foam and / or gel structured sheets.

The number of strips per pad is reduced due to the smaller format compared to the blankets of the invention. Typical pads include about 2 to 6 strips, preferably 2 to 4 strips.

Particular advantages of this pad are the good ventilation and the easy buckling behavior into stable new mold layers, e.g. during reading, watching TV or simply to adapt to the individual lying position. In addition to a contour adjustment which is also advantageous underneath the sleeping person, the use of the cushions according to the invention, in particular in combination with the blankets according to the invention, is advantageous in order to be able to achieve a uniform appearance. Accordingly, the present invention also relates to sets of blanket and cushions having such a uniform appearance.
