Description

The invention relates to a waterbed with a waterbed mattress having a water-absorbing Wasserbetthülle with a support surface, with a bottom surface and at least one side surface, wherein in the Wasserbetthülle at least one stabilizing body can be arranged and wherein the Wasserbetthülle at least one closable connection piece for filling the Wasserbetthülle with Has water or for emptying the same.

Waterbed mattresses convince by a pleasant support of the entire body without pressure points, so that the sleep in a waterbed is regarded by many people as soothing and very relaxing. However, waterbeds tend to sway. For this reason, waterbeds are now offered mostly with a stabilization or reassurance. In the waterbed cover Inserted PVC cylinders, chambers or fleece mats reduce the movement of the water and provide a calm, without negatively affecting the pleasant floating feeling.

The consumer tests different stabilization and calming levels of the waterbed when buying and chooses a suitable stabilization for him. In the production of the waterbed, the stabilizing bodies are introduced into the waterbed according to customer specifications. Subsequently, the Wasserbetthülle is welded watertight. The disadvantage here is that the selected stabilization or degree of calmness after the production of the waterbed can not be changed. An adaptation of the stabilization to new sleep habits or the increase or decrease of body weight is therefore just as impossible as a meaningful use of water beds, for example in hotel complexes in which the bed is regularly used by different people.

From the DE 10 2005 057 032 A1 an air chamber stabilization system for waterbeds is known in which the measures provided for in the Wasserbetthülle stabilizing body can be filled via a provided outside the Wasserbetthülle pump with air, so that the stabilization or degree of calmness can be influenced even after purchase, at least within certain limits. It should be noted that in addition to the degree of stabilization and the buoyancy of the degree of filling of the stabilizing body is dependent on air, so that the stabilizing body, the carrying function the water at least partially takes over and the floating feeling is affected. The benefits of the waterbed are thus not fully preserved.

Furthermore, waterbeds with massage function are known. The U.S. 4,635,620 describes a waterbed with massage function for therapeutic purposes, in which parts of the water provided in the mattress are led out of this, are pressurized and pass through braising heads back into the water bed. The braacas are oriented so that the exiting water jet from below meets the support surface of the water bed. To further support the therapeutic effect, the waterbed has a heating element that heats the water jet's water so that the person lying on the waterbed is massaged with a heated water. Furthermore, the known water bed provides that the heated water massages predefined areas of the body, eg the neck, shoulders, back, arms or legs. For this purpose, the braising heads are provided at predetermined positions. The disadvantage is that the known waterbed with massage function can only be used as a therapy device. It is due to the structure, and here, for example, due to the lack of stability, not suitable as a conventional sleeping or lying furniture, and also the considerable maintenance and installation costs prevents use in the private sector.

Object of the present invention is to develop a waterbed with a waterbed mattress such that the degree of stabilization and the comfort properties of a water bed can be easily modified even after its production and comfort-enhancing functional components can be retrofitted after purchase.
