Description

[0001] The invention relates to an orthopedic and ergonomic seat cushion suitable for people with hemorrhoid and coccyx problems. Such cushions support the buttocks of a person sitting on them without exerting painful pressure on the pathologically altered body parts in the area of ​​the hemorrhoids and coccyx. Orthopedic and ergonomic seat cushions are particularly used for disc problems, osteoporosis, or other back problems.

[0002] Common hemorrhoid pillows, for example, are designed as donut-shaped rings and contain an air, gel, or memory foam cushion. Unfortunately, this does not protect the coccyx. Furthermore, the ring can twist and flex if a person sits off-center or adopts an asymmetrical posture. The affected areas are then no longer pressure-free, and the person is required to maintain constant body tension to counteract this deformation.

[0003] Other hemorrhoid and coccyx pillows, for example, are open U-shaped pillows and contain an air, gel, or memory foam pad. While the U-shaped cutout also protects the coccyx, the pillow lacks shape stability in this area due to the two exposed U-shaped legs. The legs can open and / or twist, especially if a person sits restlessly or off-center, or adopts an asymmetrical posture. The affected areas are then no longer pressure-free, and the person is required to maintain constant body tension to counteract this deformation.

[0004] Other orthopedic seat cushions for hemorrhoid and tailbone pain feature an ergonomically shaped memory foam cushion. However, in practice, this changes its shape too drastically, as the memory foam collapses under pressure, so much so that the recess for hemorrhoid and tailbone support no longer serves its purpose.

[0005] Other hemorrhoid and coccyx cushions feature a central, elongated cutout for the hemorrhoid and coccyx. All known cushions have the cutout as a continuous opening through the cushion, allowing one to "see through" it. Tests show that under pressure from the seated person, the wall areas of the cutouts always twist / deform, which usually occurs asymmetrically and impairs the intended effect of the cushion.

[0006] CN 2 03 749 014 U1 discloses a seat cushion suitable for people with hemorrhoid and coccyx problems, with a base plate made of foam on which a person can sit with their buttocks, wherein a recess is let into the upper side of the base plate, which recess is arranged in an area in which the anus and coccyx of a person sitting on the base plate can be located, wherein the recess is completely enclosed all around in the horizontal direction by the upper side of the base plate and completely penetrates the base plate and the recess is designed in the form of an elongated hole.

[0007] AT 10 973 U discloses a device for supporting a body part of a person, wherein the device comprises a support element with a support or bearing surface for the support or reception of the body part to be supported, and the device comprises a relief device which absorbs at least part of the contact pressure arising when supporting the body part, wherein the relief device comprises at least one recess formed or shaped in the support element, and at least part of the edge regions of the recess are designed to be adapted in shape to the external shape of the body part to be supported.

[0008] It is therefore an object of the invention to create an improved orthopedic and ergonomic seat cushion for hemorrhoid and coccyx problems.

[0009] This problem is solved by an orthopedic and ergonomic seat cushion for hemorrhoid and coccyx problems with the features of the main claim. Advantageous embodiments are the subject of the subclaims.

[0010] The inventive orthopedic and ergonomic seat cushion, which is suitable for people with hemorrhoid and coccyx problems, as well as other sitting problems, initially comprises a foam base plate on which a person can sit with their buttocks. The base plate here refers to the actual support body, which must then be covered with a textile cover. The foam is preferably not memory foam, but rather a molded foam made from a two-component polyurethane foam system, with the base body manufactured using the molded foam / cold foam process.

[0011] A recess is recessed into the top of the base plate, located in an area where the anus and coccyx of a person sitting on the base plate can be located. The recess is therefore located in the area where no pressure should be exerted on the buttocks. Furthermore, the recess is completely enclosed horizontally by the top of the base plate, preventing it from accidentally expanding backward.

[0012] The recess is designed in the shape of an elongated hole, in particular an 8-shaped elongated hole. One end of the elongated hole, which is located in the area for the anus, is located in a central area of ​​the base plate, and the other end of the elongated hole, which is located in the area for the coccyx, is located in an edge area of ​​the base plate. The term "8-shaped" does not mean that the elongated hole looks exactly like a figure eight, or even has an acute-angled constriction on both sides with contact points. Rather, the shape of the elongated hole is more reminiscent of a figure eight and is designed as described below: Preferably, the elongated hole has a constriction in the region between one end and the other end of the elongated hole, with the constriction preferably being 35-70%, preferably 50-70%, of the maximum width of the elongated hole. The constriction significantly increases the dimensional stability of the elongated hole and, in particular, prevents undesired expansion or collapse of the elongated hole in its central region.

[0013] For the same reason, the thickness of the base plate below the base of the recess is 10 - 30 mm. Because the recess does not extend through the entire thickness of the base plate, the recess remains significantly more dimensionally stable, even under very asymmetrical or uneven sitting loads. Furthermore, the textile cover is simpler, as it does not have to follow the opening like with donut or U-shaped cushions. The cover can therefore be simple and full-surface with a slightly stretchy textile fabric. Furthermore, the support cushion with the cover is not immediately recognizable as a hemorrhoid cushion and features an ergonomic design, which is particularly preferred in the office. "Slightly stretchy" here means that the fabric is sufficiently elastic to fit snugly against the base plate over the long term without creasing.

[0014] If the side walls of the recess run essentially perpendicular relative to the underside of the base plate, this serves to ensure dimensional stability and clearly defines the pressure-free zones.

[0015] Preferably, the part of the other end of the elongated hole arranged close to the edge of the base plate has a larger radius than one end of the elongated hole.

[0016] If a rounded transition is provided between the side walls of the recess and the top of the base plate, the seating comfort and appearance are increased, as the recess is less visible under the textile cover.

[0017] Preferably, the rounded portion in the area of ​​one end of the elongated hole has a narrower radius than the rounded portion in the area of ​​the other end of the elongated hole, with the transition between the two radii in the area between one end and the other end of the elongated hole, particularly in the area of ​​the constriction, preferably being stepless. Accordingly, the radius of the figure-eight elongated hole is larger at the rear and upwards to reduce pressure on the coccyx when sitting, while still ensuring the desired stability of the opening with the remaining edge of the base body.

[0018] Preferably, the rounding in the area of ​​one end of the elongated hole has a radius of 5 - 20 mm, preferably 5 - 15 mm and / or in the area of ​​the other end of the elongated hole has a radius of 5 - 25 mm, preferably 10 - 20 mm

[0019] Furthermore, a rounding is preferably provided as a transition between the side walls of the base plate and the top side of the base plate, wherein the rounding preferably has a radius of 5 - 15 mm, preferably 5 - 10 mm.

[0020] The effects according to the invention could be realized if the elongated hole has a length of 170 - 230 mm, preferably 185 - 215 mm and / or at one end a width of 60 - 80 mm, preferably 65 - 75 mm and / or at the other end a width of 40 - 70 mm, preferably 55 - 65 mm and / or at the constriction a width of 25 - 55 mm, preferably 37 - 47 mm and / or a depth of 30 - 55 mm, wherein in particular the width of the elongated hole at one end is greater than the width of the elongated hole at the other end.

[0021] The effects according to the invention could be realized if the base plate has a substantially cuboid shape, preferably with a width of 360 - 460 mm, preferably 435 - 445 mm and / or a length of 320 - 410 mm, preferably 385 - 395 mm and / or a height of 50 - 90 mm, preferably 60 - 75 mm.

[0022] "Width" refers to the lateral or sideways measurement relative to a person sitting properly on the support cushion. "Length" refers to the longitudinal measurement, i.e., from front to back, relative to a person sitting properly on the support cushion.

[0023] The base plate can be ergonomically shaped. An ergonomically shaped base plate is characterized by its approximate shape, which fits the shape of the buttocks and, if applicable, the adjacent thighs, thus increasing comfort.

[0024] If the base plate has a width of 370 - 460 mm, preferably 375 - 385 mm and / or a length of 320 - 420 mm, preferably 325 - 335 mm, a cost-relevant threshold of the package dimensions is not met when shipping the cushion.

[0025] Alternatively, the seat cushion can also be designed as a wedge cushion to provide the beneficial effects of a wedge cushion to those suffering from hemorrhoids and coccyx problems. The base plate can have a wedge-shaped cross-section, with the front end of the base plate preferably having a height of 0-20 mm and the rear end of the base plate having a height of 50-90 mm. Furthermore, the base plate has a width of 360-460 mm, preferably 375-385 mm, and / or a length of 320-420 mm, preferably 325-335 mm.

[0026] The base plate preferably has a length of less than 340 mm, preferably in the range of 325 - 335 mm. This allows the cushion to be shipped below a cost-relevant threshold for package dimensions.

[0027] The support cushion conveniently includes a textile, slightly elastic, removable cover adapted to the shape of the base body, so that many color and material variations can be produced with one base body and the cover can be cleaned or replaced.

[0028] Preferably, the coating has a recess in the area covering the elongated hole that follows the shape of the elongated hole. This recess is preferably an 8-shaped recess in the shape of the elongated hole.

[0029] Preferably, a flexible mesh fabric is sewn into the recess to ensure sufficient flexibility of the cover under load and ventilation of the slotted hole. Severe deformation of the base plate can occur in the area of ​​the slotted hole and the corresponding recess, and the cover must be able to compensate for this. This function is fulfilled by the elastic mesh fabric, which is more elastic than the rest of the cover.

[0030] In principle, the cover could also be made entirely of the flexible mesh fabric, which is cheaper, but more dust and dirt can collect on the seat cushion and makes cleaning it more difficult.

[0031] If the cover is preferably made of a polyester fabric or microfiber fabric and / or the flexible mesh fabric is sewn into the recess with an embroidered seam, sufficient elasticity of the embroidered seam can be guaranteed when the cushion is loaded.

[0032] In the preferred embodiment, this results in a base plate with an 8-shaped elongated hole and an 8-shaped recess in the cover corresponding in size, position and shape, wherein an 8-shaped mesh fabric is inserted into the recess by means of an 8-shaped knitted seam.

[0033] Preferably, the cover has an anti-slip underside in the area of ​​the underside of the base body, preferably with small knobs.

[0034] The invention is based on the Fig. 1 and Fig. 2 is explained by way of example, where Fig. 1 a central section through the supervision according to Fig.2. The orthopedic seat cushion 1 has a base plate 2 made of molded foam. This forms the actual support body, which now needs to be covered with a textile cover, which is not shown here. A recess 3 in the form of an elongated hole 31 is recessed into the upper side 21 of the base plate 2. This is located where the anus and coccyx of a person sitting on the base plate are normally located. The recess 3 or the elongated hole 31 is completely enclosed horizontally on all sides by the upper side 21 of the base plate, so that the recess 3 cannot accidentally expand backwards.

[0035] One end 32 of the elongated hole 31, which is located in the area for the anus, is arranged in a central region of the base plate, and the other end 33 of the elongated hole 31, which is located in the area for the coccyx, is arranged in an edge region 23 of the base plate 21. The elongated hole 31 has a constriction 34 in the region between one end 32 and the other end 33, which significantly increases the dimensional stability of the elongated hole and, in particular, prevents undesired spreading or collapsing of the elongated hole in its central region. The constriction 34 particularly stabilizes the shape of the two ends 32, 33 of the elongated hole so that they can keep pressure loads away from the anus and the coccyx, respectively.

[0036] The side walls 36 of the recess run essentially perpendicular to the underside 22 of the base plate. The thickness of the base plate below the bottom 35 of the recess 3 is approximately 20 mm, with a maximum base plate thickness of approximately 73 mm. Since the recess does not extend through the entire thickness of the base plate, the recess 3 remains significantly more dimensionally stable, even under very asymmetrical or unsteady seating loads.

[0037] The part of the other end 33 of the elongated hole arranged close to the edge 23 of the base plate has a larger radius R1 than the radius R2 at one end 32 of the elongated hole.

[0038] Rounded edges are provided as a transition between the side walls 36 of the recess and the top side 21 of the base plate. The rounded edge in the area of ​​one end 32 of the elongated hole has a narrower radius than the rounded edge in the area of ​​the other end 33 of the elongated hole, with the transition between the two radii being seamless in the area of ​​the constriction 34. Specifically, the rounded edge in the area of ​​one end 32 of the elongated hole has a radius of 6.5 mm and in the area of ​​the other end 33 of the elongated hole has a radius of 15 mm.

[0039] A rounded area is provided around the base plate as a transition between the outer side walls of the base plate and the top of the base plate.

[0040] The drawings of the embodiment are not drawn to scale and in particular the shape and geometry of the slot may contradict the claimed dimensions.
