Definitions

• the invention relates to a cushion element according to the preamble of the main claim.
• a cushion element e.g. B.
• a mattress that is characterized by a low maximum pressure and a high support factor.
• a low maximum pressure is important for an unimpeded blood flow.
• the size of the support factor indicates how far the lumbar region through the compared to the buttocks region
• a high support factor is desirable from a biomechanical and orthopedic point of view to protect the spine and intervertebral discs, while a low maximum pressure reduces circulatory disorders.
• a high support factor usually supports the spine well, but does not allow the body to sink deep enough, especially at the protrusions. muscle This can result in tension and pressure pains.
• the sleeper is subconsciously trying to avoid the pain point by frequent changes of position and body rotation, so that depth of sleep and feeling of comfort suffer. Older people in particular, whose muscles are no longer as elastic, can feel very disturbed by the lack of sinking in of a mattress that is too hard.
• a low maximum pressure of the mattress takes that
• a plastic foam mattress has become known, which has a base part and a suspension part.
• the suspension part consists of a large number of polygonal single rods, each of which is firmly connected to the foam material at its two ends.
• DE-GM 78 29 649 is a foam spring body known for mattresses, which consists of a tubular foam part, the wall of which also has a plurality of openings and
• tubular spring bodies tend to have undesirable kink properties. If, in addition, the wall material is weakened by incisions and openings, this kinking property is increased so that optimal support cannot take place.
• the invention has for its object to provide spring bodies that allow a punctual, soft and yet strongly supportive cushioning of the body lying on it, so that optimal values for support factor, maximum pressure, pressure distribution and contact surface are thereby achieved.
• spring elements are created that have maximum load capacity
• the spring elements do not break out when compressing, but their full elasticity is selectively used as a load-bearing spring element
• the selected cylinders are therefore made of the highest density with the highest possible
• the spring elements can be higher in weight than the base, but are always considerably softer than this.
• the upholstery element base is a preferred component for a mattress with orthopedically correct values and it is always much harder than the actual spring elements.
• a cushion element that has a high body contour adaptation with high pressure relief and good
• the cushion element base is used to hold the
• the base can consist of one, two or more layers or layers or components arranged one on top of the other.
• This cushion element base is the greater hardness or strength compared to the spring elements arranged on the base, and the
• Upholstery element base serves to build up the hard part of the mattress, couch, upholstery element or
• the height of the cushion element base can be approximately 30 to 70% of the total height of the actual cushion element.
• the base can consist of products from the foam family with open or closed cells made of soft and hard foam. But it can also be made from fiber-based raw materials.
• Both the foams and the fiber base can be made of natural as well as synthetic Raw materials.
• the individual layers of the cushion element base can be structured and
• the material can be designed variably and the entire base can be perforated, perforated, punched or milled or provided with additional cavities.
• a harder base and a softer upper base arranged thereon are preferably proposed so that progressive elasticity is achieved.
• the suspension system which consists of individual spring bodies, is arranged on the cushion element base. It is possible to apply the suspension system to its own base layer, which consists, for example, of fabric, knitted fabric, fleece or the like, this layer then being placed on the top of the cushion element base.
• the spring body can on the supporting layer, i.e. H. either on the cushion element base or on the base layer provided for them, in that they are attached e.g. B. are glued that they have Velcro closures or that they are fitted into corresponding recesses of an elastic base layer.
• the spring bodies are preferably made of PUR foam or latex.
• the spring elements serve as the spring elements
• the dimensioning of the smallest spring body begins with a diameter of z. B. approx. 25 mm.
• the spring bodies can be arranged evenly or adapted to a specific requirement profile. It is also provided that the spring bodies within a mattress or a cushion part can consist of different materials, both in terms of their material composition, their static

• Foams of any kind, latex, are the elements of the invention.
• a further covering with upholstery materials can be useful for different purposes.
• this structure is directly coated with a covering made of woven, knitted, cotton fleece etc.
• the overall construction will have a frame that can be of different thicknesses. Depending on the application, however, it can also make sense to do without it.
• the individual spring bodies are arranged in such a way that they do not influence one another or influence one another only very slightly, in particular when they are deflected, so that a high point elasticity is achieved; H. everyone reacts to stress
• Spring body individually and thus elastically supports or cushions every part of the body, so that extremely high point elasticity is achieved over the entire cushion element.
• FIG. 1 shows in an exploded view, the structure of the cushion element according to the invention, in
• Fig. 2 shows a section through a base part
• Fig. 3 shows a section through a modified
• Base part denotes a base part, which can consist of one layer or, according to FIG. 2, of the two parts arranged one on top of the other
• Layers 6 and 7 is formed.
• the base part is box-shaped, the size of the actual recess 9 can be different, i. H. extends approximately over the entire length of the base part or only over part of the length, which is then to be cushioned in a special way.
• the actual suspension part 2 is placed on the base part, which in the exemplary embodiment shown consists of a support layer 8, which can be, for example, a textile fabric web, knitted fabric or the like, or an elastic support layer, on which spring bodies 4 are placed.
• the spring body 4 can be glued, clipped or fitted onto the support layer 8, and it is possible in the same way to apply the spring body 4 directly to the top of the base part 1.
• the actual spring bodies 4 can be designed differently, and the spring bodies 4a and 4b are shown as an exemplary embodiment, the spring bodies 4 being essentially cylindrical and thus in the are essentially only material-elastic, while the spring body 4b additionally has a formality which is achieved by the different design. Also, as shown in the spring body 4a, the spring bodies can be constructed from different layers.
• a layer of cushioning material 5 is applied to the suspension part and the entire structure is covered by a coating 3. It is of course possible here that the cushioning material 5 is incorporated into the cover 3 at the same time as a quilt.
• all parts of the cushion element structure according to the invention can consist of synthetic or natural materials and it is an essential feature of the cushion element structure shown that a progressive elasticity is achieved from bottom to top.
