Definitions

  • the invention relates to a flexible base as a sitting or lying pillow for the human body according to the preamble of claim 1.
  • Such a pad is known from DE-A-33 03 615, which relates to a bed, the bed surface of which is formed from approximately 200 individually inflatable elastic hollow bodies.
  • a plastic base is divided into square fields which serve as hollow-body receiving compartments.
  • the partitions necessary for the division have a height of about 15 cm and form compartments for the suitably usable hollow bodies, each of which is provided with a valve which allows air to be blown in or out.
  • the intermediate walls extend over about a third of the height of the hollow bodies, so that these have a horizontal cross-sectional area of about 10 ⁇ 10 cm 2 about 30 cm the partitions protrude.
  • the hollow bodies are therefore extremely unstable with respect to pressures acting obliquely from above, in particular if, as is indicated by way of example, they contain constrictions running horizontally in the middle to upper region.
  • the hollow bodies must therefore support each other so as not to move sideways. This can also be seen in the fact that the lateral outer walls of the bed are pulled up to the upper edge of the hollow body.
  • the position of the hollow bodies surrounding them can therefore no longer be controlled and the stability of the lying surface is considerably impaired.
  • a pad which consists of individual inflatable hollow bodies.
  • the hollow bodies In the non-inflated state, the hollow bodies are folded and are spaced from one another. When inflated, they unfold so that they lie against each other and support each other when inflated.
  • the hollow bodies are arranged in rows on their Auflaaer in two mutually perpendicular directions and have a rectangular cross-section in the inflated state parallel to their support, so that they form a closed seat or lying surface. It is therefore necessary that all hollow bodies are inflated with approximately the same pressure, since here too, if the support effect ceases to exist only one hollow body can make the entire sitting or lying surface unstable. The function of the support is therefore considerably impaired if one of the hollow bodies cannot hold the required pressure due to a leak.
  • the present invention is therefore based on the object of providing a flexible base which ensures a stable seating or lying surface even when individual hollow bodies or individual hollow body groups forming one areas compared to those of the rest Hollow bodies have different internal pressures.
  • the invention is characterized in that the hollow bodies are spherical in the filled state and the respective surface of the support facing them is dome-shaped, that the shell of the hollow body consists of a foam with closed cavities, and that the foam on the outside of the hollow body with is coated with an inelastic material.
  • the support therefore gives each hollow body a firm fit and, in conjunction with the inelastic coating, prevents the loaded hollow body from escaping, so that mutual support of the filled hollow body is not necessary. Therefore, the individual Any number of hollow bodies can be subjected to widely differing internal pressures.
  • the hollow bodies are slightly deformed by the load of the human body, so that the contact surface, which is in itself only punctiform, is considerably enlarged.
  • the hollow bodies are chosen to be sufficiently small to give the person in question the feeling of a closed seat or lying surface.
  • the volume of the voids of the foam of the shell can be changed by the pressure of the flowable medium.
  • the cavities represent air pockets that are highly heat-insulating. Depending on the pressure prevailing in the interior of the hollow body, these cavities are compressed to a greater or lesser extent so that the heat transfer resistance of the casing decreases when the pressure inside the hollow body rises. It is therefore possible to give the sitting or lying person a pleasant feeling of temperature by appropriately adjusting the internal pressure of the hollow body.
  • a suitable foam for this purpose consists of neoprene
  • This coating advantageously consists of a knitted fabric.
  • the hollow body is preferably provided with a valve for the controllable entry and exit of the flowable medium.
  • FIG. 1 two adjacent hollow body 1 are shown, which are supported by a support 2.
  • the hollow bodies 1 are pressurized from the inside by a gas or a liquid and take on a spherical shape.
  • the support 2 has dome-shaped depressions at the locations provided for receiving the hollow body 1, which are adapted to the spherical shape of the hollow body 1.
  • the hollow bodies 1 therefore lie firmly in the dome-shaped depressions on the surface of the support 2 and are thus secured against lateral deflection.
  • the shell of the hollow body 1 is preferably made of coated neoprene.
  • the hollow body 1 can be produced, for example, in such a way that two flat blanks made of foam or the like are connected to one another by an annular adhesive bond, the adhesive bond being additionally secured by a seam or a clip.
  • a flowable medium preferably air
  • a valve not shown
  • a compressed air source At the other end of the hose 4 there is a compressed air source. It is also possible to control the compressed air source itself in a suitable manner. Since the base has a large number of hollow bodies 1, periodic pressurization can be carried out without this being perceived as uncomfortable by the person lying down. In this way, the development of pressure ulcers can be avoided in patients who are immobile for long periods.
  • the arrangement of the hollow bodies 1 in adjacent rows is in one, i.e. 2 offset in the horizontal direction by half the distance between two adjacent hollow bodies 1 in order to obtain the largest possible number of hollow bodies 1 on a given surface.
  • the support 2 is provided with a raised edge 5 which follows the mutually offset ends of the individual rows of hollow bodies.
