Description

field of invention

The invention relates generally to the field of pillows, such as support pillows, sleeping pillows, neck pillows, neck support pillows or the like. In particular, the invention relates to a support pillow for supporting a head and/or neck of a user of the support pillow.

Background of the Invention

A variety of different support pillows have been developed over the past few decades. These can differ, for example, with regard to a geometry, a dimension, a filling material, a thickness and/or a hardness.

However, conventional support pillows cannot usually be individually adapted to the needs and/or requirements of a user. Conventional support cushions therefore often have to be offered in different variants by a manufacturer in order to at least partially meet the individual requirements and/or needs of different users. The document U.S. 2007/245493 A1 discloses a support pillow according to the preamble of claim 1.

Summary of the Invention

Embodiments of the present invention advantageously allow the support pillow according to the invention to be adapted by the user himself. The support pillow according to the invention is also characterized by a particularly comfortable and soft surface. The invention is defined by the features of claim 1.

One aspect of the invention relates to a support pillow for supporting a user's head and/or neck. The support pillow can in particular be designed as a sleeping pillow, a neck pillow and/or a neck support pillow. The support pillow has an at least partially viscoelastic filling material, an inner cover which is at least partially filled with the filling material and encloses the filling material, and an outer cover which encloses the inner cover. The inner cover has an opening through which the user can fill additional filling material into the inner cover and/or at least part of the filling material can be removed from the inner cover, so that a filling volume, a thickness, a dimension and/or a hardness of the support pillow can be customized by the user.

In principle, the support cushion can have any geometry, such as a cube-shaped, a cubic, a cuboid, a cylindrical, a conical, and/or a spherical geometry.

The at least partially viscoelastic filling material can denote a filling material which consists at least partially of viscoelastic material and/or of material with viscoelastic material properties. In particular, the filling material can therefore be a solid. The viscoelastic filling material can in particular have a viscoelastic foam and/or a viscoelastic foam. However, it should be mentioned that the filling material also contains other components may have, which do not necessarily have viscoelastic material properties.

The inner cover can define an inner volume of the support pillow, which is at least partially filled with the filling material. At the same time, the inner volume of the support pillow can be an inner volume of the inner cover, which can be filled with the filling material. The inner cover can be sack-shaped or designed in any other way.

Additional filling material, for example in addition to a filling material already located in the inner volume, can advantageously be introduced into the inner volume of the inner cover and/or the support pillow via the opening of the inner cover. Alternatively or additionally, filling material located in the inner volume can be at least partially removed from the inner volume of the inner cover and/or from the support pillow via the opening. This allows the user to adapt the support pillow individually to his needs by removing filling material and/or adding filling material. In particular, the user can adjust a thickness, a height, a filling volume, a dimension, a hardness, a degree of hardness, a weight and/or a total volume of the support pillow in this way, in particular without having to make further changes and/or adjustments to the support pillow, such as such as unraveling or sewing up a seam of the inner cover, would be required. Furthermore, due to the configuration of the support pillow according to the invention, a manufacturer of the support pillow can offer the support pillow in a variant and at the same time cover the needs of all possible users. This, in turn, may allow the support pillow to be produced and marketed cost-effectively.

The outer cover can also enclose the inner cover and the filling material arranged in the inner cover. For example, the external reference to this have an opening through which the inner cover at least partially filled with the filling material can be introduced into the outer cover. The opening of the outer cover can be reversibly closable, for example with a zip fastener, a Velcro fastener, an adhesive fastener, a hook fastener, a button fastener and/or a snap fastener.

According to one embodiment of the invention, the inner cover is at least partially air-permeable and/or breathable. Alternatively or additionally, the outer cover is at least partially air-permeable and/or breathable. As a result, deformability of the support cushion can advantageously be increased, since air can escape from the inner volume and/or flow into the inner volume.

According to one embodiment of the invention, the opening of the inner cover is a closable opening, in particular a reversibly closable and/or reclosable opening. This can allow a user to adjust the support pillow and/or the filling material multiple times and without wear by removing and/or adding filling material.

According to one embodiment of the invention, the support cushion has a closure device for reversibly closing the opening of the inner cover, the closure device having a zipper, a button closure, a snap fastener, a Velcro fastener, a hook fastener and/or an adhesive fastener. Such locking devices can be characterized in particular by robustness, reliability and/or long-term functionality.

According to one embodiment of the invention, the support pillow is essentially cuboid, with the inner cover and/or the support pillow having two essentially parallel long sides and two essentially parallel narrow sides has, which each run transversely to the long sides. The narrow sides are each shorter than the long sides, with the opening of the inner cover being formed on at least one of the narrow sides of the inner cover. For example, a user can position his head on the support pillow in such a way that his neck runs essentially parallel to the narrow sides of the support pillow. By arranging the opening on one of the narrow sides, it can thus be ensured that the user does not feel the opening and/or a closing device of the opening. Overall, the user's well-being can be increased during use of the support cushion.

According to one embodiment of the invention, the inner cover has two openings. The two openings can be arranged on two opposite narrow sides of the inner cover. This can allow a user to fill in additional filling material on the two opposite narrow sides and/or to remove filling material. It should also be mentioned at this point that alternatively or in addition to the opening on the narrow side, the opening and/or another opening can be arranged on at least one or both long sides. The inner cover thus has at least one opening, but can also have two, three or four openings.

According to one embodiment of the invention, the filling material is washable, so that the inner cover with the filling material arranged therein and/or the entire support pillow can be washed by the user. Alternatively or additionally, the filling material can be washed without shrinking and/or without losing viscoelasticity, so that the inner cover with the filling material arranged therein and/or the entire support cushion can be washed by the user. This can simplify handling of the support cushion and/or save costs, such as cleaning costs. This can also increase hygiene. It should be mentioned at this point that the filling material can also include non-washable viscose foam.

According to one embodiment of the invention, the filling material has a visco-foam which is at least partially visco-elastic and/or has visco-elastic material properties. As a result, the support properties of the support pillow can be significantly improved. However, the filling material can also have additional components. In general, visco-foam can refer to a foam-like material with visco-elastic material properties.

According to one embodiment of the invention, the filler material comprises a plurality of flakes and/or a plurality of elongate elements of filler material. The flakes can denote, for example, shreds and/or shred-like elements. The flakes can have any size distribution and/or geometry. In particular, the flakes can be angular, round, oval, cube-shaped, cuboid, cubic, polygonal and/or polygonal. Different flakes of fill material may have different dimensions and/or geometries. The elongate filling material elements can refer to strip-shaped, rod-shaped, thread-shaped and/or rope-shaped elements, which can have any desired cross-section, such as round, rounded, angular, rectangular and/or polygonal. Different filling material elements can have different dimensions, lengths, geometries and/or cross-sections.

According to one embodiment of the invention, the filling material and/or the visco foam has a compressive strength of 0.9 kPa to 2.5 kPa, in particular around 1.1 kPa to around 1.8 kPa.

According to one embodiment of the invention, the inner cover has a respective stabilization layer on two opposite inner surfaces of the inner cover for mechanical stabilization of the support pillow. The stabilization layers can be fastened on the inside to the inner surfaces of the inner cover, for example glued and/or sewn. A shape and/or geometry of the support cushion can advantageously be stabilized by the stabilization layers. According to one embodiment of the invention, each of the stabilization layers consists at least partially of viscose foam, in particular completely of viscose foam. Alternatively or additionally, the inner surfaces of the inner cover each face the filling material.

According to one embodiment of the invention, the inner surfaces of the inner cover are each covered completely and/or over the entire surface by one of the stabilization layers. The two stabilization layers can have an identical thickness or different thicknesses. The stabilization layers arranged on the inner surfaces of the inner cover can also be designed in one piece.

According to the invention, the outer cover has a cover material, with a three-dimensional (3D) spacer knit being formed at least on an outside of the cover material and/or the outer cover, at least in a partial area of the outer cover. On the outside, the cover material and/or the outer cover has a honeycomb structure, a honeycomb structure and/or a honeycomb mesh structure with recesses open to the outside.

The outside of the outer cover can denote the side facing a user and/or the side facing away from the inner cover. The knitted spacer fabric can have, for example, a spacer structure with stitches made from knitted monofilament or multifilament spacer threads. Due to the structural composition of spacer fabrics, these can be more elastic than spacer fabrics, which can increase comfort for the user of the support pillow, since the outer cover with spacer fabric can be made soft, elastic and pleasant to the touch. In addition, the honeycomb structure on the outside of the support pillow allows air to circulate and moisture removal from the support pillow can be increased.

The honeycomb-like recesses open to the outside are not only advantageous in terms of air exchange and moisture transport as well as the compensation of temperature fluctuations in general, but also enable increased elasticity, which offers the user a soft feel and also allows the outer cover to be optimally adapted to the user lying on it, without this being adversely affected by the brittle spacer threads that are often noticeable in spacer knitted fabrics.

The outer cover can be produced, for example, on a large circular knitting machine working according to the so-called 3-way technique with a high throughput over time and therefore high cost-effectiveness.

The recesses of the mesh structure are preferably provided in a regular arrangement on the outside of the cover material and/or the outer cover, although an irregular arrangement, for example an arrangement forming a pattern, is also conceivable.

The honeycomb-like recesses open to the outside can be variable in terms of their geometry, for example round and/or oval and/or angular in terms of their open cross section.

According to one embodiment of the invention, the cover fabric and/or the outer cover made of 3D spacer fabric is formed in at least two layers with an upper layer forming the outside and a fabric layer preferably made of polyester fiber fabric forming an inner layer.

The inner layer can thereby form a smooth fabric layer, which can also be jacquard and, for example, provided with a pattern, and on which the upper layer of the 3D spacer fabric can be formed from textured, twisted yarn, in particular multifilament yarn, towards the outside.

The honeycomb recesses can extend at least essentially over the entire thickness of the upper layer, i.e. from the outside to the inner layer or close to it, in order to achieve optimal climate control with regard to the exchange of air and moisture between the two sides of the cover fabric to allow. In addition, the depth of the honeycomb recess increases the softness of the upper layer made of 3D spacer fabric, which means that an improved feel can be obtained.

The cover material and/or the outer cover can also be constructed in three layers. For example, the cover fabric may be a middle layer knitted with the top layer with a monofilament yarn as a filler. As a result, with simultaneous high air and moisture permeability, stabilization and volumization of the 3D spacer fabric, which is often desired in terms of feel, can be achieved. According to a preferred embodiment, the monofilament yarn can be formed from polyester, but other synthetic fibers such as fibers formed from polyamide can also be used for this purpose.

In order to give the outward-facing surface or outside of the spacer fabric a particularly smooth and pleasant feel, the surface surrounding the honeycomb-like recesses can be formed from particularly fine knitted stitches.

Studies have shown that it is particularly advantageous with regard to comfort and microclimate control if the upper layer of the spacer fabric has a weight proportion of 50% to 70%, in particular 55% to 60%, of the cover fabric and/or the outer cover.

The inner layer can have a weight proportion of 20% to 30%, in particular 25% to 30%, of the cover material and/or the outer cover.

When using a filler, optimal results in terms of air permeability, stabilization and volumization were determined with a weight proportion of 10% to 20%, in particular 15% to 20%, of the middle layer on the cover fabric and/or the outer cover.

The cover material and/or the outer cover can have a weight of 200 g/m ² to 300 g/m ² , so that it can have the required durability and at the same time is easy to handle in terms of its weight during production and use.

The outer cover can be formed on all sides of the support pillow, ie on the top, on the bottom, on the long sides and on the narrow sides. The outer cover can completely enclose the inner cover. However, it is also conceivable to design different sides of the support cushion and/or the outer cover differently. The same design of all sides can allow a particularly simple manufacture.

In order to enable the insertion and removal of the inner cover, it is advantageous if the outer cover has an at least partially peripheral closure, in particular a zip fastener.

Examples of possible embodiments of the outer cover are summarized below.

The outer cover has a cover material and/or is made of a cover material which has a 3D spacer fabric at least on one outside and a honeycomb-like mesh structure on the outside has open recesses.

The cover fabric and/or the outer cover can be made of at least two layers of 3-D spacer fabric with an upper layer of textured, twisted yarn, in particular multifilament yarn, forming the outside, and an inner layer of preferably smooth polyester yarn.

The cover material and/or the outer cover can be constructed in three layers with a middle layer knitted with the upper layer with a monofilament yarn as a filler, the monofilament yarn preferably being made of polyester or polyamide.

The honeycomb recesses can extend at least essentially over the thickness of the upper layer and optionally the middle layer.

The upper layer can have a weight proportion of 50% to 70%, in particular 55% to 60%, of the cover fabric and/or the outer cover.

The inner layer can have a weight proportion of 20% to 30%, in particular 25% to 30%, of the cover material and/or the outer cover.

The middle layer can have a weight proportion of 10% to 20%, in particular 15% to 20%, of the cover fabric and/or the outer cover.

The cover material and/or the outer cover can have a mass per unit area of 250 g/m ² - 300 g/m ² .

The cover material and/or the outer cover can be of the same design on all sides.

These and other aspects of the invention are explained below with reference to the accompanying drawings.

The support pillow 10 is in the in the Figures 1A to 4 shown embodiment configured cuboid. However, the support pillow 10 can have any other desired geometry. The support pillow 10 can in particular have a size of 40 cm by 80 cm.

The support pillow 10 has two essentially parallel long sides 12a, 12b and two narrow sides 14a, 14b which run transversely and/or orthogonally to the long sides 12a, 12b and are shorter than the long sides 12a, 12b.

The support pillow 10 has an outer cover 16 and an inner cover 18 . The inner cover 18 is arranged in the outer cover 16 and the outer cover 16 encloses the inner cover 18.

In Figure 1A the inner cover 18 is arranged completely in the outer cover 16, so that the outer cover 16 completely encloses the inner cover 18 figures 2 and 3 the inner cover 18 is only partially arranged in the outer cover 18 to illustrate the structure of the support pillow 10 . In the figures 4 and 5 the support pillow 10 is shown without an outer cover 16 in each case.

The long sides 12a, 12b and the narrow sides 14a, 14b of the support pillow 10 can be long sides 12a, 12b and narrow sides 14a, 14b of the inner cover 18 and/or the outer cover 16. The narrow sides 14a, 14b can be around 40 cm long in particular and the long sides 12a, 12b can be around 80 cm long in particular.

In order to insert the inner cover 18 into the outer cover 16, the outer cover 16 has an opening 17 arranged on the long side 12a, on which a zip fastener 19 for opening and/or closing the opening 17 is arranged. Alternatively or additionally, at the opening 17, a Velcro, a Button closure, an adhesive closure, a snap fastener and / or a hook closure can be arranged.

The outer cover 16 has a cover material 50 and/or is formed from a cover material 50 .

An outside of the outer cover 16 can in particular be seamless.

The recesses 54 preferably have an oval cross section towards the outside, which in the unstressed state can be approximately 2 mm to 4 mm wide and approximately 3 mm to 5 mm long. The webs of material 56 of spacer fabric 51 located between the recesses 54, which are offset and arranged regularly relative to one another, are dimensioned at least approximately the same in terms of their width.

The outer cover 16 and/or the cover material 50 is present as a three-layer 3D spacer knitted fabric with an upper layer 58 forming the outer side 52, which is made of textured, twisted multifilament yarn made of polyester, and a middle layer which also forms the spacer knitted fabric 51 and is knitted with the upper layer 58 Layer 60 is formed from a brittle polyester monofilament yarn serving as a filler and a layer of plain polyester yarn knitted to the top layer 58 and middle layer 60 forming an inner layer 62 .

The upper layer 58 has a fine knit structure 64 on the outside 52, which gives the surface a soft feel.

In terms of thickness, the top sheet 58 in the one shown is advantageous Execution dimensioned such that it occupies at least 70% to 80% of the total thickness of the cover fabric 50 in order to use the microclimatic advantages of the spacer fabric 51 as far as possible.

In order to enable the greatest possible air circulation and optimal moisture transport to the outside, the honeycomb recesses 54 extend essentially across the thickness of the upper layer 58 and the middle layer 60 to adjacent to the lower layer 62, so that the cover material 50 can pass through the recesses 54 at the same time has a high degree of flexibility and extensibility in width. The elasticity in the height causes a softness, which can be defined by the filler of the middle layer 60 depending on the desired degree of softness.

It goes without saying that the cover material 50 and/or the outer cover 16, depending on the application, can be knitted with all known spacer knitting methods on circular knitting machines and with all known finishing methods, such as e.g. B. with a washing, bleaching and shrinking process following the knitting process.

The inner cover 18 has an opening 20 on the narrow side 14a. Furthermore, the inner cover 18 has an inner volume 22 which is filled with a filling material 24 .

In particular, the opening 20 can be arranged centrally on the narrow side 14a and have a length of 10 cm to 20 cm, for example. In particular, the opening 20 can extend along the narrow side 14a over approximately 10% to 100%, for example 15% to 60%, of the entire length of the narrow side 14a.

At the opening 20, the inner cover 18 has a zipper 26 as a closing device 26, with which the opening 20 can be opened and/or closed. Alternatively or additionally, a Velcro fastener, a button fastener, an adhesive fastener, a snap fastener and/or a hook fastener can be arranged at the opening 20 . At least one further opening 20 and/or at least one further closing device 26 can also be arranged on the further narrow side 14b and/or on at least one of the long sides 12a, 12b. The closing device 26 can extend over the entire length of the opening 20 . Correspondingly, the closure device 26 can be at least 3 cm, and in particular at least 5 cm, long. Furthermore, the locking device 26 can have a maximum length of the length of the narrow side 14a. In other words, the locking device 26 can be formed only in a partial area of the narrow side 14a or along the entire length of the narrow side 14a. In particular, the locking device 26 can be arranged centrally on the narrow side 14a and have a length of 10 cm to 20 cm, for example. In particular, the locking device 26 can extend along the narrow side 14a over approximately 10% to 100%, for example 15% to 60%, of the entire length of the narrow side 14a.
