Definitions

  • the invention relates to a seat cushion or a body pad with at least partial pressure relief in the region of projections of the body parts or prominences resting on the seat cushion or pad.
  • the utility model DE 297 07 932 U1 discloses a storage device, such as a cushion, in the form of a loose-filled with bulk material envelope, which can be either inflated with pressure or applied to a vacuum.
  • a storage device such as a cushion
  • z. B. be fixed by applying vacuum, but this is relatively disadvantageous in terms of handling and complicates a location-independent and problem-free use without pump or vacuum aids.
  • the utility model DE 86 09 488.2 U1 discloses a seat cushion with a fixed plate-shaped base frame, which is spanned for cushioning with elastic layers.
  • the plate-shaped base frame has rectangular in the area of Weghöcker Breakthroughs on.
  • the elastic padding layers can be pressed while sitting up in the openings, after which a punctual contact with the Weghöckem should be prevented.
  • the object was to provide a lightweight, portable and usable without further preparation seat cushion, which reliably prevents pressure points in the area of the seat bumps and is applicable to all seats without special additional designs.
  • the seat cushion or the body pad is considered to be a vertical one, i. formed in the thickness direction of the pad or the pad, substantially one-piece or monolithic elastic body and has one or more in the region of the projections of resting on the seat cushion or pad body parts or prominence (protrusions of body parts) arranged recesses ,
  • a monolithic elastic body could for example consist of a foamed elastic plastic or of viscoelastic material. It is therefore light, portable and easily placed on all seating.
  • the recesses of different shape, size and texture advantageously in the area of the human buccal cusps (tuberosity ischii) and / or in the region of the coccyx, cause a pressure relief and thus a pleasant and pain-relieving effect.
  • the particularly advantageous pressure relief in the area of Weghöcker leads to a fatigue-free sitting without pressure pain and otherwise physical tension.
  • the seat humps belong to the pelvis. Their centers have a distance of about 130 mm in the male and about 150 mm in the female sex. Of course, there are deviations of about 25%.
  • the pressure point, ie the pressure surface of the seat bumps has a diameter of about 25 mm.
  • body documents with recesses of different shape, size and texture can also be used advantageously for z.
  • the recesses are formed either in the vertical upper region of the seat cushion or the pad or as a vertical direction through holes.
  • foamed plastics bores can easily by z. B. punching process can be introduced.
  • a further advantageous embodiment is that the seat cushion or pad at least partially wedge-shaped, z. B. only in its front part, and is formed with by decreasing thickness and the recesses are arranged in the rear higher part.
  • a further advantageous embodiment is that the seat cushion or pad is formed at least partially wedge-shaped and with decreasing thickness to the rear and the recesses are arranged in the higher part. This makes comfortable reclining possible, for example in armchairs with adjustable backrest.
  • two recesses are arranged on both sides of the longitudinal axis of the seat cushion or the base, the centers are each between 40 and 120 mm, preferably between 65 and 75 mm away from the longitudinal axis, wherein the opposite edges of the two recesses measured over the center a minimum distance of 50 mm have.
  • the center of the above-mentioned pressure surfaces above the buccal cushions varies, depending on anatomical design, but most significantly between the male and female anatomy, ie, between the formation of the male and female pelvis.
  • the pressure point, ie the pressure surface of the seat bumps has - as shown above - a diameter of about 25 mm, depending on the addition of the covering and anatomically varying soft tissue formations around and over the humps.
  • the diameter of the recesses in each case must be greater than the Weghöckererbreite, ie be on average about 110 mm.
  • the distance between the opposite edges of two recesses should be at least 50 mm as measured above and above the center line.
  • distance of the recess from the rear edge of the seat cushion is about 90 mm, but depends on the varying sitting habits.
  • the advantageous embodiment described below is recommended in the the region surrounding the recesses have a different elastic material to the edge regions of the seat cushion.
  • An average total length of a seat cushion is about 500 mm, unless an extended support for the thighs is sought.
  • shapes and characteristics of the pillow are conceivable, such as round or oval shapes, flattened or rounded edges, anatomically adapted shape contours on buttocks, etc.
  • a further advantageous embodiment is that the elastic body is coated with an elastic layer material whose modulus of elasticity is different from that of the elastic body, for example at least 10% smaller than that of the elastic body, i. that the elastic strain or compression of the layer material at the same (pressure) load is greater than the elastic strain or compression of the elastic body.
  • the seat cushion can be surrounded by a protective layer material without the stretching of the layer material, which likewise takes place when the pad is used, hindering the required expansion of the elastic body.
  • the layer material can cover or span the recesses in the unused state of the cushion, or else be applied in such a way that the recesses are visible.
  • a further advantageous embodiment is that in the area surrounding the recesses a different elastic material is arranged to the edge regions of the seat cushion or the pad. If, for example, an approximately 20 mm wide annular area of a flexible plastic foam around the recesses and surrounds these areas up to the edges of the pillow with a less elastic plastic foam, we obtain a high pressure relief of Weghöcker and at the same time very comfortable and firm buttock support for motor vehicle seats.
  • the seat cushion or pad is at least partially provided with a non-slip coating.
  • a non-slip coating prevents, for example in motor vehicles, the so-called “submarining", i. the slipping of the pelvis under the lap belt.
  • such a coating is used for the secure fixation of seat cushions and persons in wheelchairs, for example.
  • the seat cushion is designed as an insertable upper molding of a seat construction.
  • excellent fixation of the seat cushion can be achieved, especially if the seat construction is concave in the broadest sense and the seat cushion can at least partially enclose the edges. This facilitates, for example, the fitting of the seat cushion in motor vehicle seats.
  • a further advantageous embodiment is that the seat cushion or pad is formed as foldable or foldable via a joint, wherein the joint is formed essentially of correspondingly shaped or bonded layer material.
  • a particularly pleasant and advantageous sitting comfort, or lying comfort results from the fact that the seat cushion or the body pad of a polyurethane and / or polyether soft foam with a density of 30 to 60 kg / cm 3 and a compression hardness of 3.5 to 7 Kpa exists.
  • the foams are in this case with a density of 48 kg / cm 3 and a compressive strength of 5 Kpa used as they are available commercially as under the protected name ContiPur 5050, or foams with a density of 38.5 kg / cm 3 and a compressive strength of 5 Kpa used as they are available under the protected designation ContiPur 4050 commercially.
  • Fig. 1 shows an inventive seat cushion 1 for a motor vehicle seat on the left side in section A-B and on the right side in the view with marked cut line.
  • the seat cushion 1 has recesses 2 and 3 formed as through holes in the area of the seat bumps and consists of the upper part 4 and the lower part 5.
  • the upper part 4 and the lower part 5 are wedge-shaped to match each other and transition-free, as can be seen in the sectional view.
  • Upper part 4 and lower part 5 of the seat cushion 1 are also provided on both narrow sides and merging into each other with lateral-concave bulges 6, which are complementary to the shape of the laterally convex in the seat of a motor vehicle seat side beads formed.
  • the annular region 7 surrounding the recesses 2 and 3 is made of flexible plastic foam, while the remaining regions consist of a less elastic plastic foam up to the edges of the pad.
  • Upper part 4 and lower part 5 of the seat cushion 1 are each covered individually with an elastic, non-slip layer material 8, wherein this an elastic fabric cover for the seat cushion-forming layer material is sewn so that in the point 9 results in a kind of joint.
  • the lower part 5 can be folded up to transport the seat cushion in the direction of the arrow 10 (folding direction).
  • Fig. 2 shows once again the seat cushion 1 in the folded state in section.
