Definitions

  • the invention relates to a mattress with at least one elastic body.
  • Known mattresses have one or more composite body made of foam and / or latex. To improve the comfort of lying, it is often desirable to vary the hardness of the mattress over its length and / or width, the surfaces of the mattress should remain pleasantly soft. In known mattresses made of foam and / or latex this is from the body in areas where the mattress should be less hard, so the weight of a user should give more easily, locally cut or cut material. An increase in certain areas, however, is not feasible in this way. In addition, once cut out areas within the body can not be moved.
  • the hardness profile of the mattress that is to say the hardness of the mattress over its surface, can not be subsequently adapted individually at the place of use, for example, to the size and / or weight of a person.
  • Object of the present invention is to design a mattress of the type mentioned so that the hardness / the hardness profile of the mattress is easy especially even at the place of use changeable.
  • the base body has at least one channel in which at least one spring rake can be arranged, which comprises an elongate elastic torsionable web, to which a plurality of spring arms is attached, which are each arranged substantially transversely to the web.
  • the inherently soft, elastic body is individually equipable with spring rake over which the local hardness of the mattress according to the weight of a user and according to the weight distribution is customizable.
  • the basic idea here is that the bridge due to its torsional ability point loads that act on the spring arms compensated. With a punctiform load on one of the spring arms, a torsional moment is exerted on the web and this is twisted.
  • the spring arms are arranged so that the rotation of a spring arm, an adjacent spring arm is tensioned so that it counteracts the load and the mattress hardens in the load.
  • the spring rakes can also be easily removed or replaced with a spring rake with other spring characteristics.
  • the spring arms may be formed similar to bent leaf springs.
  • the spring arms may alternately incline along the ridge once to an upper side and once to an underside of the mattress.
  • the spring arms inclined to the top / bottom of the mattress can be bent back in the area of their free ends from the top / bottom of the mattress.
  • the ends of the spring arms gently nestle substantially tangentially against the adjacent cover layers of the mattress core, which as a rule are made of foam material, so that a point load is distributed over the cover layer material over a large area for this reason.
  • the spring arms may be arranged in pairs mirror-symmetrically to a plane containing the longitudinal axis of the web or to the longitudinal axis of the web. In this way, not only adjacent, but additionally opposing spring arms are used for load distribution.

In this way, the hardness or the hardness profile of the mattress can also be easily adapted at the place of use by inserting, removing or replacing spring rakes to the needs of the user.
  • a plurality of spring rakes with different spring effects, in particular different hardnesses and / or hardness distributions over the length of the mattress can be arranged distributed in the main body. In this way, especially in the back and lumbar area another mattress hardness can be specified as in the head or leg area. Also, such a variation of the hardness of the mattress can be given to their edges.
  • a plurality of spring rakes can be arranged at different distances to an upper side of the mattress in the main body. In this way, the hardness profile of the mattress is also adaptable over the depth of the mattress.

  • connecting means for an articulated, in particular pivotable, connection of the webs of adjacent spring rakes are formed. This allows relative movements between the spring rakes connected to the corresponding connecting means without significant elastic deformations of the spring rakes and / or connecting means occurring in the process.
  • Such an articulated, in particular pivotable, connection of the spring rakes is in an application of the mattress in conjunction with an adjustable, in particular motor-driven, Bettrah- men or slatted frame of interest, since this defined kinks in the mattress are advantageous.
  • the connecting means are designed such that a pivoting movement of adjacent spring rakes take place about a pivot axis " , which is aligned at least substantially parallel to the webs of the adjacent spring rakes.
