DESCRIPTION:

BRIEF SUMMARY
The invention concerns a surface element having an air-permeable carrier provided with an adsorbent.
Many areas in daily life such as in relation to seats and chairs, shoes, domestic textiles, clothing, sports uses or the like involve the problem of achieving a given comfortable atmosphere or climate. Seats such as vehicle seats, child safety seats, office chairs, upholstered seats or chairs or the like involve a sitting atmosphere or climate which often leaves much to be desired. In the case of shoes it is inter alia shoe inserts, the insole or the lining that influence or adversely affect the atmosphere or climate within the shoe. Domestic textiles can involve blankets, mattresses, incontinence products etc in which the atmosphere or climate often also leaves much to be desired. The atmosphere involved in connection with clothing in the form of work protective clothing, motorcycle clothing, ABC-clothing and the like also correspondingly leaves something to be desired. Sports uses involve for example rucksacks, rucksack supports, back cushions, joint protectors, gloves, helmets or the like. In these cases also the desired atmosphere often leaves something to be desired.
The above-mentioned atmosphere which often leaves something to be desired results from the fact that moisture produced by a person is not adequately carried away, that is to say transported away.
The object of the present invention is to provide a surface element of the kind set forth in the opening part of this specification, with which the moisture is carried away in the optimum fashion or which is suitable for absorbing and temporarily storing moisture in an optimum fashion or transporting moisture away from the respective source thereof so as to afford good climate comfort.
In a surface element of the kind set forth in the opening part of this specification, in accordance with the invention that object is attained in that the adsorber carrier is in the form of a surface or flat element which is connected in areal relationship to an absorbent, moisture-storing fleece layer by needling to give an air-permeable composite material, wherein the needling is oriented from the fleece layer to the adsorber carrier and the fiber barbs or burrs of the needling extend from the fleece layer to the adsorber carrier and through the latter.
The surface element according to the invention is advantageously suitable for transporting moisture generated by a moisture source to the adsorber carrier and to the fleece layer. In that situation the fleece layer is firstly saturated with moisture. At the same time moisture is stored in the adsorber carrier and in the absorbent of the adsorber carrier. After saturation of the fleece layer further excess moisture can be stored in the adsorber carrier and in the adsorbent of the adsorber carrier. If then at a later time the source of moisture is no longer present, that is to say it is separated from the surface element according to the invention, then regeneration of the surface element according to the invention occurs in an advantageous manner, that is to say moisture is given off by drying in the ambient atmosphere. At the same time this arrangement advantageously ensures that smells or odors are bound in by the adsorbent.
In the surface element according to the invention the adsorber carrier can comprise an open-pore foam material which is provided with adsorber particles. The foam material is preferably a plastic foam such as a PU-foam. The foam material may be provided with the adsorber particles at its external surface and in its interior, that is to say on the pore walls or in the pores. The adsorber particles can be provided in one grain size or grain fraction or in different grain sizes or fractions. The adsorber particles may involve activated carbon particles or other per se known adsorber particles such as zeolites or the like.
The adsorber carrier can also comprise a fleece material or a textile material and can be provided with suitable adsorber particles. A further possibility is that in the surface
