Description

[0001] The invention relates to a mattress system. In particular, the invention relates to a mattress system comprising a climate-controlled mattress.

[0002] With climate-controlled mattresses, air is either supplied to or extracted from the sleeping surface. This either removes or adds humidity and / or heat to the body of the mattress user or the bed itself. Air circulation under the duvet is determined by the local pressure conditions within the bed. The problem with this is the potential for drafts, which arise primarily from an airflow towards the user's body, especially in sensitive areas. With simple air extraction, targeted temperature and humidity control within the bed is not possible.

[0003] The invention thus addresses the problem of providing a mattress in which the microclimate within the bed can be influenced by the user and adjusted according to their individual preferences. Furthermore, drafts should be avoided in sensitive areas of the body, and air circulation under the duvet should be increased.

[0004] According to the invention, this problem is solved by a mattress system with the features of claim 1. Advantageous embodiments and further developments of the invention are described in the following dependent claims.

[0005] The invention relates to a mattress system comprising a mattress with mattress edges, with a lying area arranged in the middle of the mattress and with an edge area running between the lying area and the mattress edges, wherein the mattress has - a foot area located at the edge, which is airtight towards the foot side of a person lying on the mattress, - a head area located at the edge, which is airtight towards the head of a person lying on the mattress, - at least two air distribution areas running along the edge of the mattress between the foot and head areas, and - at least two structurally separate climate control chambers that fill the lying area of ​​the mattress and can be removed and inserted from the lying area, wherein the mattress system further comprises at least one fan device designed to extract exhaust air from one of the air distribution areas and / or to supply air to one of the air distribution areas; wherein at least one of the air conditioning chambers has an inlet area for air to flow from an adjacent air distribution area into this inlet area, and / or at least one of the air conditioning chambers has an outlet area for air to flow from these outlet areas into an adjacent air distribution area of ​​the mattress.

[0006] The advantages achievable with the invention, besides providing a climate-controlled mattress with flexibly adjustable climate chambers, include the fact that the supply and extraction of climate-controlled air within the mattress can be individually and flexibly adjusted to the user's body zones, thus optimizing air circulation under the duvet. The combination of air supply and extraction with adjustable zoning allows for the satisfaction of different climate control needs through customizable zoning.

[0007] In the context of this invention, the feature "airflow-tight" does not mean that no air molecules can pass through the airflow-tight elements at the molecular level. The tightness must be such that no significant portion of the airflow striking the airflow-tight element can pass through. This typically means much less than 10%, preferably less than 5%, of the volume airflow can pass through the element.

[0008] Preferably, the fan assembly comprises at least one fan and a housing. The fan assembly further preferably includes sensors and means for air modification and is sealed on both the pressure and suction sides of the mattress.

[0009] Preferably, the mattress is designed with two air distribution zones along its longitudinal sides. Each of the climate control chambers preferably has an air-permeable connection to one of the air distribution zones, while being airtight to the other. The climate control chambers are each preferably made of filter foam that is air-permeable.

[0010] In a preferred embodiment, the at least two air distribution areas and / or the foot area are constructed of air-permeable foam and / or mesh fabric. This allows air to flow through them or it in the direction of the air conditioning chambers.

[0011] Preferably, the at least two air distribution zones are separated from each other by means of airtight barriers. These barriers create an area within the mattress that is airtight at both the foot and head ends, while the two edge zones of the mattress are designed to allow air to flow in or out to form the at least two air distribution zones. The barriers are preferably made of airtight foam. Advantageously, the climate control chamber located at the foot end is encased in airtight foam between the two edge zones, thus defining a separation zone between the two air distribution zones. This area is therefore sealed in such a way that no significant portion of the airflow can pass between the air distribution zones via a short-circuit airflow connection.

[0012] Preferably, at least one fan unit for supplying or extracting air from the air distribution areas is arranged in and / or at the foot of the mattress. Advantageously, the mattress system has one or two fan units. While the mattress system with one fan unit is more cost-effective, the mattress system with two fan units can supply air at different temperatures to two different air distribution areas.

[0013] In a further preferred embodiment, the climate control chambers in the lying area have vertically extending, airtight chamber barriers that vertically limit the chamber volume of the climate control chambers. These airtight chamber barriers are designed to be sealed against one another and can be individually inserted or removed to allow airflow between the climate control chamber and an adjacent air distribution area and / or another adjacent climate control chamber. The chamber barriers are made, for example, of rigid foam, such as viscoelastic foam or coated comfort foam, or closed-cell foam such as PE (polyethylene) foam. The chamber barriers are preferably detachably connected to the climate control chambers, for example, by bonding the materials, by a sufficiently sealing coating, or by sufficiently sealing hook-and-loop fasteners.The airflow-tight chamber barriers can also be designed separately and not connected to the air conditioning chambers, with sufficient mutual sealing in the mattress system being formed by press fit.

[0014] Preferably, the mattress has a mattress cover that is airtight in a base area of ​​the mattress and around the edges of the mattress.

[0015] In a preferred embodiment, the mattress has a mattress cover with a top surface made of an air-permeable textile. The air-permeable textile is advantageously made of 3D mesh, and the mattress cover is preferably designed as a porous and air-permeable fabric or as a filter foam. The mattress cover is preferably arranged as a covering over the head area, the climate control chambers, and the foot area, i.e., positioned above and covering them. Position and direction specifications refer to a standard operating position of the mattress system.

[0016] Preferably, the mattress cover is attached to the climate control chambers on one side along the edges by means of a detachable connection. Advantageously, the mattress cover is attached to the climate control chambers on one side along the edges by means of a hook-and-loop fastener. This minimizes ventilation short circuits between the climate control chambers.

[0017] In a preferred embodiment, the mattress below the climate control chambers is made of mattress foam. Preferably, the mattress foam is a conventional comfort foam with so-called ergonomic cuts, for example in the form of perforations.

[0018] The at least two climate control chambers are advantageously designed so that they can be removed and inserted by hand. This allows for easy installation, removal, and modification without tools.

[0019] In a preferred embodiment, the mattress system further comprises at least one temperature control unit configured to temper the supply air to a predetermined temperature. The temperature control unit is preferably integrated into the fan unit. The fan unit can also be configured to measure air temperature, humidity, and air quality, and to modify these parameters and purify the air.
