Definitions

• the present invention relates to a clothing accessory known as a "crotch liner", Table 1 Fig.
• the object of the invention is also to maintain the part of the body that rests on the saddle dry, hygienic and ventilated at all times, in particular encouraging the flow of blood at the level of the perineal muscles; the air cushion of Table.2 Fig.5 , is in fact arranged to promote physiologically the complete rest of the anatomical areas on the saddle, maintaining the blood supply constant avoiding inflammations, aches and pressure sores.
• the crotch liner of the invention is moreover very light and exceptionally breathable because most of the surface is occupied by air between the three-dimensional structures of the fabrics Table.2 Fig.4 e Fig.5 , is also very hygienic because the hydrophobic fibre does not retain humidity/sweat on which bacteria could proliferate, as occurs in traditional crotch liners containing polyurethane foam or other open-cell materials.
• the three-dimensional fabrics Table.2 Fig.3 consist of a lower multifilament fabric surface connected to a second upper fabric surface that is also formed of multifilaments by a monofilament that is tough and sufficiently stiff to keep said surfaces well spaced apart from one another, thus creating a space between the surfaces and forming a true air chamber.
• the three-dimensional fabrics used have a particular property that is known as compression set and is measured in kPa (kiloPascal), this determines the thrust that connects and maintains spaced apart the two surfaces of the three-dimensional fabric and is generated by the diameter of the internal monofilament; the pressure set absorbs the pressure of the body and absorbs the vibrations and shocks coming from the frame of the bicycle.
• the object of the invention is thus a crotch liner for "on-saddle" activities that underneath the covering fabric has an air cushion that is anatomically set up for the male and female perineal / ischiatic regions, characterised by several layers of three-dimensional fabrics that are superimposed on one another, Table.2 Fig.5 and disclosed here below:
• the second three-dimensional fabric Table.2 Fig.5 -C positioned in the central part of the "cushion", has a decisively resistant weave, is 7.5 mm thick, has about 120 monofilaments xcm2, a compression set of 1 1 kPa and permeability to the air of 2600 litres/dm2xmin; this three-dimensional fabric has been placed in the centre of the "cushion” in order to permit a greater air flow and less sensitivity with the saddle.
• the third three-dimensional fabric Table.2 Fig.5 -D near the saddle, 5mm thick, has about 430 monofilaments xcm2, a compression set of 4 kPa and permeability to the air of 2200 litres/dm2xmin, so it is fairly soft and contributes to increasing the shock-absorbing effect and the "pump" effect of the constant delivery and expulsion of air.
• the layers of the three-dimensional fabrics are superimposed on one another to obtain different compression sets and densities that are able to support morphologically different regions of the body that rest on the saddle; the positioning of the three three-dimensional fabrics will be different if the crotch liner is used by a man or a woman because the perineal anatomical region differs between the sexes, so the shape of the air cushion may have different shapes.
• the structure inside the air cushion Tav.2 Fig.5 the detailed description of which was set out in the previous points, can be made with a greater or lesser number of three- dimensional fabrics, with three-dimensional fabrics having a thickness range from 0.5mm to 20mm, with a number of monofilaments varying from 700 to 50 per cm2 and with a compression set varying from 1 to 80kPa; with these parameters, an air cushion structure can always be obtained with a greater or lesser compression set and with greater or lesser permeability to the air but always within the conceptual scope of the invention.
• the combination of the three three-dimensional fabrics assembled together in the order listed above creates, inside the crotch liner, an air cushion Tav2 Fig.5 and is insulating and mechanically comfortable; all the yarns that form the three three-dimensional fabrics are hydrophobic, 100% polyesters; so humidity does not collect and the weight increase is avoided that occurs in traditional crotch liners, further, bacterial proliferation and the formation of odours is avoided.
• the invention made in the 3 layers as disclosed above permits perfect ergonomic adaptation to the human body and more precisely in the perineal /ischiatic region, avoiding undesired obligations and compressions.
• the three fabrics are coupled together with thermoplastic points to enable maximum breathability and permeability to the air; not even the slightest amount of polyurethane foam is used, not even as an adhesive, the three fabrics are then heat-sealed and without the use of any stitching.
• the pressure of the body is distributed and unloaded on the saddle by the different compression sets of the three-dimensional fabrics, providing maximum comfort for the user.
• the crotch liner is thus:
• the crotch liner dries much sooner than the fabric of the shorts, thus permitting a rapid functional reuse thereof.
