FIELD OF THE INVENTION
This invention relates to seat pads for shorts, in particular for cyclists shorts.
BACKGROUND OF THE INVENTION
Bicycling has several advantages over other means of transport. It is very efficient, it is good for the cardiovascular health of the person practicing this sport, it is environmentally friendly since no toxic wastes are generated per se, it is lightweight, it takes little storage space when not in use, it is easy to handle through heavy road traffic, it can access narrow roads not accessible by larger vehicles, etc..
Governments in developed and developing countries promote its use.
Among its disadvantages, there are the safety considerations from road hazards, the absence of adverse weather shielding, and physical strain associated with long duration trips. In particular, there is a problem of comfort linked to the seat, and also a possible health hazard connected to the load biases applied by the seat to the genital parts of the cyclist. For example, in man, possibly damaging compressive forces whose direction, frequency and magnitude are often unpredictable are applied by the seat ._._.~....,,~._. ~.......,.,...,... .
.. _........-.,,.._,.---.,--...~, directly to the scrotum and indirectly to the prostate. In woman, possible damaging shearing or shaffing forces are applied by the seat to the vulva labiae.
The present invention is therefore directed at addressing the issues raised by the bodily injuries that can be sustained as a consequence of riding on a bicycle seat, by providing an ergonomically designed seat pad destined to fit against and be stitched to the inside crotch portion of a cyclist pant.
SUMMARY OF THE INVENTION
The invention relates to a flexible seat pad for mounting into the inside crotch portion of a cyclist pant, said seat pad comprising: a) a thick intermediate layer made from resiliently compressible material; b) a thin top layer made from a non-compressible sheet material; and c) a thin bottom layer made from a non-compressible sheet material; wherein said intermediate layer has a variable thickness and said seat pad is sized and shaped so as to conformingly fit against the inside crotch portion of a cyclist pant, for dynamic comfort of the cyclist during pedalling.
Said intermediate layer could consist of open cell foam, preferably polyurethane.
Said top layer could consist of a synthetic material, preferably polyester, most preferably brushed micro-fiber polyester. Said bottom layer could consist of a soft synthetic material, preferably polyester felt.

Figure 5 is a cross-sectional view at an enlarged scale of a portion of this seat pad;
and Figure 6 is a perspective view of a cyclist pant shown in phantom lines, with the seat pad illustrated in full lines in its crotch position into this cyclist pant.
DETAILED DESCRIPTION OF THE EMBODIMENTS
As shown in figures 1-3 of the drawings, the seat pad 10 consists of a sheet member 12 being pretensioned into generally upwardly convex shape, with its front end portion 14 and its rear end portion 16 being raised relative to the intermediate section thereof 18.
As shown in figure 1, the front portion 14 is narrower than the rear end portion 16, and defines a generally semi-cylindrical shape in front end view.
As shown in figures 2 and 4, the seat pad 10 includes eight different ?:hick pad bulges 20, 22, 24, 26, 28, 30, 32 and 34, being separated from one another in adjacent pairs by thinned out hinge lines 36. The intermediate pad bulge 20 and the adjacent front pad bulge 22 each has a smaller overall thickness relative to the other pad bulges, preferably of about five millimeters (5 mm), whereas each of the two rear pad bulges 24, 26, adjacent the intermediate pad bulge 20 has a larger overall thickness relative to the other pad bulges, preferably of about 10 mm thickness. Along each of the two opposite lateral side edges of the intermediate pad bulge 20, there is found a pair of narrow but elongated side pad bulges 28, 30, and 32, 34. The edgewise side pad bulges 28 and 32 have the smallest overall thickness relative to the other pad bulges, preferably of about 3 mm thickness, while the inner side pad bulges 30, 34, adjacent to the intermediate pad bulge 20 also have a smallest overall thickness relative to the other pad bulges, but preferably slightly thicker than pad bulges 28 and 32. Preferably, intermediate pad bulge 20 has about 4 mm of thickness.
As illustrated in figure 5, the seat pad consists of three layers of material:
a) a thick yet compressible intermediate layer 38 of open cell foam, for example polyurethane or other "air breathing" foam material;
b) a thin top layer 40 made from a non-compressible sheet material, preferably a synthetic material such as polyester, most preferably brushed micro-fiber polyester; top layer has preferably between 0,5 to 1 mm thickness; and c) a thin bottom layer 42 made from a non-compressible sheet material, preferably a soft synthetic material, most preferably polyester felt; bottom layer 42 has preferably between 0,5 to 1 mm thickness.
As illustrated in figure 6, the felt layer 42 of the seat pad 10 is preferably directly stitched flatly and conformingly to the crotch portion of the cyclist pant. However, the seat pad 10 could alternately be mounted in free ........._~ ..._._.... _.__.. . _ _ _.._ ,.....__ _ __..__._ _ _.
..,...,.....,,._.~....~..~ ..~
floating fashion onto the crotch portion of the cyclist pant. This felt layer 42 is for example of the unweaved tufted type, or other soft material kind to the cyclist crotch skin.
As shown in figure 5, the micro-fiber polyester layer 40 includes shallow air and/or moisture circulation channels 44 that further promotes surface diffusion of air and bodily fluids transpiration. Channels 44 preferably have between 0,25 to 0,5 mm in depth, i.e. about half the thickness of the polyester layer 40. Each channe144 may be cross-sectionally U-shape, as shown in figure 5, but a V-shape or other suitable trough shapes are not excluded from the scope of the present invention, provided this channel is able to convey fluids along the surface of the seat pad.
The hinge lines 36 are made by heat stamping and by compression. When the hinge lines 36 are formed, the open cell foam material is laterally released so that the top and bottom polyester layers 40, 42 become fused with one another, as sho'%Arn in figure 5. Accordingly, no - or very little - open cell foam layer remains at the hinge lines 36 between the two opposite surface layers 40, 42. The hinge lines 36 will have for example a total thickness of about 1 to 2 mm.
The general molding process is preferably performed by an ultrasound gun. The results are such that the thick various pad bulges 20-34 are hinged to one another by the thin hinge lines 36, and these pad bulges are of varying overall thickness -as per varying permanent compression of the intermediate compressible open cell Eoam _ _ __..~....._._.._..._ .,...~,..-v_._ ....,_._ _ ......~......,,~
layer 38, to provide optimum comfort at the genital areas. This optimum comfort is brought about by the fact that, due to the modulated thickness of the seat pad sheet member 12, adjusted compressive forces are applied by the seat pad 10 to the crotch body parts of the cyclist, thus substantially reducing the discomfort to the genital areas by accommodating the thickness of the sheet member 12 to the corresponding adjacent anatomical topography of the person.
The pretensioned frontward and rearward flaring of the front and rear sheet portions 14 and 16 again provide snug anatomical conformation to the cyclist crotch portion, again enhancing overall comfort.
