    The invention is defined by the appended independent claims withembodiments being set forth in the appended dependent claims, in thefollowing description and in the drawings.
    According to a first aspect, there is provided an inflatable/deflatablemassage cell for a vehicle seat, the massage cell having a first major surfaceand a second major surface, which major surfaces are arranged onsubstantially opposite sides of the massage cell, the cell being configured forfluid connection with a fluid system for inflation/deflation of the massage cell,wherein the massage cell is curved in the deflated condition such that the cellpresents a generally convex first major surface.
    The fluid used for inflating a massage cell is typically a gas such asambient air, or any other suitable fluid.
    The first and second major surfaces of the massage cell are connectedalong the periphery to form an inflatable/deflatable massage cell. The cellmay be provided with an opening for connection to the fluid system.
    That the first major surface of the massage cell is convex in thedeflated condition means that even after a plurality of inflations/deflations thefirst major surface remains convex in its deflated condition.
    A surface normal to the convex first major surface is pointing awayfrom the massage cell, i.e. outwards.
    Depending on the degree of inflation, the first major surface of themassage cell may or may not present any convexity in the inflated condition.
    The curved massage cell could e.g. be used in the back of a seat, seatcushion, in armrest, side cushion etc. lt is also suitable for other seats thanvehicle seats, such as different kind of rest chairs. When placed underneaththe cover of a seat in such a way that the convex major surface of themassage cells is arranged outwards towards the surface of the seat, i.e. asurface normal to the convex surface is pointing towards the cover of theseat, there is less seat show through than with planar massage cells, as theedges of the massage cell are arranged inwards pointing away from the trim.Hence, there is also less wear on the seat cover from edges of the massagecells compared to planar cells. Further when using curved cells there is lessrisk of the cell folding over in case of over inflation.
    Further, the massage cell in the deflated condition may present agenerally concave second major surface.
    Alternatively, the second major surface of the massage cell is notconcave but substantially planar, such that the massage cell is curved on onlyone side, i.e. through the generally convex first major surface.
    The generally convex first major surface and the generally concavesecond major surface may be substantially complementary surfaces.
    The massage cell may substantially be made of plastics. The plasticmaterial may be a plastic film, foil or sheet. The plastic material could e.g. bepolyethylene, polypropylene, polyester, polyvinyl chloride or polyurethane. lnone example the plastic material is thermoplastic polyurethane (TPU) foil. Thematerial should be sealable to form the cell and facilitate the increase involume of the cell as the cell is filled with fluid.
    The first and second major surfaces of the massage cell may be ofsubstantially the same material. Alternatively, the material of the first andsecond major surface may not be the same. The second major surface maybe of a more rigid or less flexible material than the material of the first majorsurface, e.g. if the second major surface is not concave but substantiallyplanar.
    The first major surface may be single curved.

    Alternatively, a concavity of a cross sectional curve, which is obtainedfrom a cross section taken through the convex first major surface such thatthe cross section comprises the largest convexity of the first major surfaceand a surface normal to the convex first major surface, may comprise alargest and a smallest radius of curvature.
    The largest radius of curvature may be 30-300%, 50-250%, 75-200%or 100-150% of a length of the cross sectional curve and the smallest radiusof curvature may be 20-99% of the largest radius of curvature.
    The largest radius of curvature may be located at a centre portion ofthe cross sectional curve and the smallest radius of curvature at a peripheralportion of the cross sectional curve.ln one example both peripheral portions of the cross sectional curvemay have a smaller radius of curvature than a centre portion.ln one embodiment the smallest radius of curvature is located at acentre portion of the cross sectional curve and the largest radius of curvatureat a peripheral portion of the cross sectional curve.ln an alternative embodiment the generally convex first major surfacemay be double curved such that two mutually orthogonal cross sections, afirst and second cross section, of the convex first major surface comprises arespective convexity and a respective surface normal to the convex first majorsurface.

    Detailed Descriptionln Fig. 1 an inflatable/deflatable massage cell 1 is shown in its deflatedcondition. The massage cell 1 has a first major surface 2 and a second majorsurface 3, which major surfaces are arranged on substantially opposite sidesof the massage cell 1. The massage cell 1 is provided with an opening forconnection with a fluid system for inflation/deflation of the cell (not shown).The massage cell 1 is curved in the deflated condition such that the cellpresents a generally convex first major surface 2 and a complementarygenerally concave second major surface 3. Alternatively, the second majorsurface may be substantially planar (not shown).ln Fig. 2 three massage cells 1, 1', 1" are arranged in a massage cellarrangement 4 in a series of successive massage cells such that twosuccessive massage cells overlap each other in a main direction of extensionX of the series of cells. All cells 1, 1', 1" in the series of successive cells areoriented in the same direction and are substantially aligned along the maindirection of extension X with a length of a major surface of a massage cell (indeflated condition) extending substantially in the main direction of extension Xof the series of successive cells.
    The overlap of adjacent massage cells 1, 1'; 1', 1" may be such that afirst massage cell covers 10-99% of a second massage cell 1. ln Fig. 2 suchoverlap is about 30%.
    As seen in Fig. 2, the massage cells 1, 1', 1" are connected to a majorsurface of a support structure 5 in such a way that a surface normal of thegenerally convex first major surface of a cell 1, 1', 1" substantially is pointingin a direction which is orthogonal to the main direction of extension X of theseries of successive massage cells and substantially pointing away from themajor surface of the support structure 5 to which the massage cell isconnected.
    The support structure 5 may comprise one sheet or two connectedsuperimposed sheets. The support structure 5 having a first and secondmajor surface arranged on substantially opposite sides of the supportstructure. The cells 1, 1', 1" may be connected to a first or second majorsurface of the support structure 5. The support structure 5 may be of weldablematerial such as plastics. The cells 1, 1', 1" may be of weldable material andconnected to the support structure 5 by means of welding. Alternatively, thecells 1, 1', 1" could be connected to the support structure 5 be means of e.g.gluing.lt is also possible to arrange the massage cells in a multi-cell (notshown) comprising at least two connected massage cells comprising at leasta base massage cell and a top massage cell. Internal spaces of the massagecells in the multi-cell are in fluid communication with each other and themassage cells are oriented in the same direction and arranged on top of eachother. The top massage cell and the base massage cell in a multi-cell may bearranged offset in relation to each other, such that a top-cell covers 10-99% ofa base-cell. The base massage cell may be connectable to a fluid system forinflation/deflation of the multi-cell.
    When placed under the cover of a seat the curved massage cells, i.e.single cells 1, multi-cells or a plurality of cells 1, 1', 1" in an overlapping cellarrangement 4, should be arranged in such a way that a surface normal of theconvex major surface of the massage cell 1, 1', 1" is arranged pointingoutwards towards the underside of the cover.
    As seen in Figs 1 or 2, the first major surface 2 ofa massage cell 1, 1',1" may be single curved.
    A concavity of a cross sectional curve 100 (see Figs 3 or 4), which isobtained from a cross section taken through the convex first major surface 2of a cell 1, 1', 1" such that the cross section comprises the largest convexityof the first major surface 2 and a surface normal to the convex first majorsurface, may have substantially the same radius of curvature R1, R2, R2'along the cross sectional curve as in Fig. 3.
    The radius of curvature R1, R2, R2' may be 30-300%, 50-250%, 75-200% or 100-150% of a length of the cross sectional curve 100.11ln one non-limiting example the first major surface 2 of the massagecell 1, 1', 1" is of substantially rectangular shape in the deflated condition,the rectangle having a first side of about 65 mm and a second side of about60 mm. The largest convexity of the first major surface 2 is arranged asshown in Fig. 1 and the radius of curvature of the cross sectional curve isabout 80 mm along the cross sectional curve.
    Alternatively, as shown in Fig. 4, the concavity may comprise a largestradius of curvature R1 and a smallest radius of curvature R2, R2'.
    The largest radius of curvature may be 30-300%, 50-250%, 75-200%or 100-150% of a length of the cross sectional curve and the smallest radiusof curvature may be 20-99% of the largest radius of curvature.ln Fig. 4 the second smallest radius of curvature R2, R2' of the crosssectional curve is about 30% of the first largest radius of curvature R1.
    As in Fig. 4, the largest radius of curvature R1 may be located at acentre portion of the cross sectional curve 100 and the smallest radius ofcurvature R2, R2' at a peripheral portion of the cross sectional curve 100.ln Fig. 4, there are two substantially opposite peripheral secondsmallest radius of curvature R2, R2' which are of approximately the samesize.
    Alternatively, the smallest radius of curvature may be located at acentre portion of the cross sectional curve 100 and the largest radius ofcurvature at a peripheral portion of the cross sectional curve.
    Alternatively, the major surface may be double curved (not shown).ln such case, the generally convex first major surface may be doublecurved such that two mutually orthogonal cross sections, a first and secondcross section, of the convex first major surface comprises a respectivesurface normal to the convex first major surface and a respective convexity. Alargest radius of curvature of a first cross sectional curve obtained from thefirst cross section may be 30-300%, 50-250%, 75-200% or 100-150% of alength of the first cross sectional curve.
    A discussed above, the major surfaces 2, 3 of the massage cell indeflated condition may be rectangular. Other substantially polygonal or semi-polygonal shapes are also possible as well as round or oval shapes.12Different sizes, shapes and curvature of the massage cells may berequired depending on where the cell is to be located and if it is to be used asa single cell, in a multi-cell, in a series of overlapping single cells or series ofoverlapping multi-cells.
    One way of manufacturing the inflatable/deflatable massage cell 1 isillustrated in Figs 5a-5c. A first material sheet 40 and a second material sheet41 with substantially the same shape as the first sheet are arranged on top ofeach other. The major surface area of the second sheet 41 is smaller than amajor surface area of the first sheet 40, Fig. 5a. The first sheet 40 is hereplaced in a sheet holder 42 having a concave surface 43, Fig. 5b, and thesecond sheet 41 is placed as a “lid” such that connection along peripheraledges thereof is possible, Fig. 5c. The first material sheet 40 may be held inplace in the holder be means of a vacuum exerted on the first material sheet.lf the first and second sheets are weldable at least at the peripheral edgesthereof welding, such as electric welding, may be used for the connection ofthe two sheets, such that a massage cell 1, Fig. 5d, is formed having agenerally convex first major surface 2 and a generally concave second majorsurface 3, which major surfaces are on substantially opposite sides of themassage cell 1.
    Alternatively, the second major surface is substantially planar indeflated condition and may be of a material which is more rigid than thematerial of the first major surface.ln another method of manufacturing a massage cell, Figs 6a-6d, a firstand second material sheet 50, 51 are provided, Fig. 6a. The first sheet 50 ishere placed in a sheet holder 52 having a concave surface 53, Fig. 6b, andthe second sheet 51 is placed as a “lid”. The first sheet 50 may be held in theholder 52 by means of vacuum exerted on the first material sheet 50. Thesheets are connected, Fig. 6c, in such a way that the total area used of thesecond material sheet 51 in the massage cell 1 is smaller than the total areaused of the first material sheet 52 and such that the massage cell obtains thedesired shape. The sheets 50, 51 may be connected through e.g. welding.The formed massage cell 1, Fig. 6d, has a generally convex first majorsurface 2 comprising the first material sheet 50 and a generally concave13second major surface 3 comprising the second material sheet, which majorsurfaces 2, 3 are on substantially opposite sides of the massage cell 1.Alternatively, the second major surface may be substantially planar.
    Any excess material of the first and/or second material sheet not beinga portion of the massage cell 1 may be removed trough e.g. cutting, indicatedas dotted vertical lines in Fig. 6c.
    The methods may also comprise a step of providing the massage cell 1with an opening (not shown) for connection with a fluid system, such that thecell may be inflated/deflated. This opening may be provided by leaving anopening between the first and second material sheets during the connectionof the sheets. Alternatively, the opening could be provided in the massagecell aften/vards.
    With these methods of manufacturing massage cells 1 it is possible toadapt the curvature of the curved cell to the position in the seat where it is tobe located by e.g. adapting the total surface area of the first 40, 50 andsecond material sheet 41, 51 used in the massage cell 1.
    The first and second materials sheets or at least portions thereof usedin the methods may be of weldable materials and the step of connecting thesheets then comprises welding of the materials.
    The first 40, 50 and second material sheets 41, 51 used for making amassage cell 1 may be of the same material. Also, the thickness of thematerial sheets may be the same. Alternatively, the first and second materialsheets may be of different materials and/or thickness, flexibility etc.
