The technical field relates to a seat pad for a pair of cycling pants and, more particularly, to a flexible seat pad for fitting onto the buttock, the lower abdominal, and perineum regions of a cyclist or any person wearing the seat pad.
Increased popularity of cycling, at both recreational and competitive levels, has resulted in a demand for high quality, low cost cycling apparels which are effective at providing the user with bodily comfort during sustained periods of cycling.
Particularly, considerable attempts have been made at developing cyclist pants which provide the cyclist with increased comfort during contact of the body with the cycle seat. Typically, during cycling, a substantial portion of the cyclist's body weight bears on the cycle seat. Additionally, when peddling, the cyclist's body undergoes considerable movement relative to the cycle seat resulting in frictional contact therebetween. Such weight bearing and prolonged frictional contact are known to cause certain discomforts including minor abrasions and, in some instances, more serious injuries suffered at the lower abdominal region of the cyclist.
Existing cyclist pants include multi-layered seat pads affixed to the inside crotch area of the pants. Such seat pads are designed to increase comfort by providing a padded buffer between the cyclist and the cycle seat during use. However, such known seat pads are often bulky and result in the unintended consequence of adding to the cyclist's discomfort upon the cycle seat. For instance, such seat pads are known to be less flexible than desired, thus increasing discomfort of the cyclist.
There is thus a need for a seat pad which combines both properties, i.e. cushioning where needed and sufficient flexibility.
It is an aspect of the invention to improve comfort of cyclists wearing cycling garments with seat pads.
It is therefore an aim of the present invention to address the above mentioned issues and to provide a seat pad and a cycling garment including the same which provide effective padding against contact with the cycle seat with an increased flexibility.

It will be noted that throughout the appended drawings, like features are identified by like reference numerals.
The term “cycling garment” is intended to mean cycling pants, shorts or knicks, bicycling pants, shorts or knicks, baggy shorts or pants, bib shorts or pants, and other similar items.
The seat pad includes a front portion 22, an opposing rear portion 24, and an intermediate portion 26 disposed between the front and rear portions 22 and 24, respectively. The front portion 22 is generally U-shaped and is designed to contact and support the lower abdominal region (or the lower pelvic region) of the cyclist. The rear portion 24 of the seat pad 20 is somewhat bird tail-shaped and is substantially wider than the front portion 22. The rear portion 24 is generally oriented to align with the buttocks region of the cyclist and includes two seat surfaces 28 spaced-apart from one another. As it will be described in more details below, a rear elongated groove 30 extends between the two seat surfaces 28. The intermediate portion 26 serves to connect the front and rear portions 22 and 24, respectively, and includes curvilinear contouring along sides thereof. When the seat pad 20 is properly utilized by the cyclist, the intermediate portion 26 contacts the perineum region, between the legs, and upper thigh regions thereof.
Central padded areas 32 are disposed centrally on the seat pad 20. In the embodiment shown, the padded areas 32 are located in the intermediate portion 26 and the rear portion 24. However, in an alternative embodiment (not shown), the padded areas 32 can also be located in the front portion 22 to provide additional support and padding to the cyclist's lower pelvic area.
The seat pad 20 further includes an outer area 34 which extends substantially around a periphery of the padded areas 32. The padded areas 32 include padding, as discussed further herein, and are substantially thicker than the outer area 34. The outer area 34 may include padding similar to that of the padded areas 32 or, alternatively, the outer area 34 may be relatively flat, or have differing degrees of padding.
The padded areas 32 include two spaced-apart buttocks padded areas 36 disposed and designed for contact with the buttocks of the cyclist. The padded areas 32 further include a perineum padded area 38 extending forwardly from the buttocks padded areas 36 along a longitudinal axis A-A into the intermediate portion 26 of the seat pad 20. The perineum padded area 38 is intended for contact with the perineum area of the cyclist.
The padded areas 32 can further include a front padded area 239, as shown in
One skilled in the art will appreciate that the shape, number, and configuration of padded areas can vary from the one shown in the accompanying drawings.
As mentioned above, the outer area 34 extends around the padded areas 32 and includes side wings 40 disposed generally at the intermediate portion 26 of the seat pad 20, adjacent to the perineum padded area 38. The side wings 40 can be pre-shaped (or pre-tensioned), i.e. extending downwardly into a concave shape, to provide snug anatomical conformation to the cyclist's perineum and upper thigh regions, again enhancing overall comfort.
Thinned hinge lines 42 separate the buttocks padded areas 36 from the perineum padded area 38. The thinned hinge lines 42 are portions of the seat pad 20 having a reduced thickness. The thinned hinge lines 42 allow an area of the seat pad 20 to pivot, or otherwise move, relative to another portion. In alternative embodiments (not shown), additional thinned hinge lines can traverse a perimeter of the padded areas 32 separating the same from the outer area 34 and further thinned hinge lines can extend across the outer area 34 or within the padded areas 32.
The hinge lines 42 can be formed by permanently compressing the padded areas 32 to obtain the desired reduced thickness thereof. For instance, the compression can be achieved by heat treatment or by a high frequency fusion treatment.
While the thinned hinged lines 38 are described herein and throughout with regard to specific dispositions thereof on the seat pad 20, this is in no way intended to limit the scope of the formation and the positioning of the hinge lines 42. As mentioned, such lines 42 provide the seat pad 20 with an advantageous degree of flexibility. Accordingly, the thinned hinge lines 42 may be disposed at any position on the seat pad 20 as desired to provide enhanced flexibility thereto, addition comfort and/or to bring any additional advantages thereof to the seat pad 20.
In an embodiment, the seat pad 20 is a multi-layered element including an inner (or top) layer 62, a middle layer 63, and an outer (or bottom) layer 64 as shown in
While various individual layers of the seat pad 20 are herein specified, this description is only exemplary and is not intended to limit or otherwise narrow the invention. The seat pad 20 may include any number of layers in any potential combination thereof as desired for achieving the comfort properties and padding provided by the seat pad 20. Further, it shall be understood that the layers composing the seat pad 20 may individually be formed of a uniform, monolithic material construction or, alternatively, such layers may themselves be composed of a plurality of material layers. Thus when describing and reciting “a layer” of the seat pad 20 herein, any of these constructions are contemplated, as well as combinations and variations thereof. In another alternative embodiment, the seat pad 20 can include two layers a top layer and a bottom layer, which is also a padding layer.
The top layer 62 is generally composed of a cloth-like material. That is, the top layer 62 includes a thin, generally non-compressible, woven fibrous material formed of, for example, polyester such as brushed micro-fiber polyester. The top layer 62 includes a thickness of approximately 0.2 to four millimeters (0.2-4 mm) and, in another embodiment, approximately 0.3 to two millimeters (0.3-2 mm).
The middle layer 63 is a padding layer and can be composed of thick compressibly resilient open-cell foam, such as polyurethane or another “air breathing” material, or appropriate gels. The middle layer 63 includes a thickness of approximately ten to fifteen millimeters (10-15 mm). In the embodiment of the seat pad 20, the foam padding material composing the middle layer 63 may include a plurality of layers, as further described in US patent application no. 2007/0174953, incorporated herein by reference in its entirety. Furthermore, the foam density can vary within the seat pad 20.
The bottom layer 64 is composed of a cloth-like material. That is, the bottom layer 64 includes a thin, generally non-compressible, woven fibrous material formed of a synthetic polymer, such as a polyamide, for example nylon. The bottom layer 64 includes a thickness of approximately 0.2 to two millimeters (0.2-2 mm) and, in another embodiment, approximately 0.3 to one millimeter (0.3-1 mm).
The top layer 62, the middle layer 63, and the bottom layer 64 are fixed together to form the multi-layered seat pad 20. The various layers are fixed together in any sufficient manner which establishes a lasting bond therebetween. For example, the layers may be temperature bonded, high frequency fusion bonded, affixed together by use of an ultrasound gun, adhered together with an adhesive such as glue, etc. During this bonding process the materials of the various layers may be compressed or otherwise made smaller as desired to achieve a final seat pad 20 of a specific thickness. For example, top, middle, and bottom layers having original thicknesses of one millimeter (1 mm), fifteen millimeters (15 mm), and one millimeter (1 mm), respectively, may be compressed or reduced to form into the seat pad 20 having a maximum thickness of approximately fifteen millimeters (15 mm) or less.
Thus to define the several padded areas 32, outer area 34, and hinge lines 38 having distinct thicknesses, the multi-layered seat pad 20 can be in a fully expanded state in few regions, a partially compressed state in other regions, and in a compressed state in still other regions.
Furthermore, the seat pad 20 fabricated as discussed above, can include a plurality of regions having distinct thicknesses due to overlapping or non-overlapping of the top, middle, and bottom layers. That is, due to the varying shapes and sizes of the layers composing the seat pad 20, some areas of the pad 20 include all three layers overlapped and in an uncompressed state and thus include a maximum thickness, while other areas of the pad do not include all of the layers overlapped upon each other, partially compressed, entirely compressed or uncompressed, and thus these areas include a reduced thickness.
In a particular embodiment, the front portion 22 of the seat pad 20 has a thickness of approximately two millimeters (2 mm). The side wings 40 of the intermediate portion 26 have a thickness of approximately one millimeter (1 mm). The front and external padded areas 38a and the rear padded area 38c of the intermediate portion 26 have a thickness of approximately twelve millimeters (12 mm) and the front and internal padded area 38b extending between the external padded areas 38a has a thickness of approximately ten millimeters (10 mm). The padded areas 36 of the seat surfaces 28 have an increasing thickness from the peripheral padded area 36a to the central padded area 36c. More particularly, in the embodiment shown, the peripheral padded areas 36a of the seat surfaces 28 have a thickness of approximately seven millimeters (7 mm), the intermediate padded areas 36b of the seat surfaces 28 have a thickness of approximately twelve millimeters (12 mm), and the central padded areas 36c of the seat surfaces 28 have a thickness of approximately fifteen millimeters (15 mm). The section 66 extending between the seat surfaces 28 has a thickness of approximately one millimeter (1 mm). It is appreciated that the thicknesses given above are exemplary only. The materials composing the various regions of the pad 20, and the construction thereof, provide the cyclist with sufficient support, enhanced padding against shock and impact, increased flexibility, temperature control, and moisture absorption and evacuation.
As exemplified above, the padded areas 32 and the outer areas 34 contouring the padded areas 32 are relatively thick. Therefore, the flexibility of this seat pad 20 in the rear portion 24 is relatively limited. During the pedaling operation, as a first leg, for instance the right leg, is extended, the corresponding right buttock member moves downwardly in response thereto and at the same time that the right leg is extended, the left leg moves upwardly by a proportional amount. Similarly, the left buttock member moves upwardly in proportion to the downwardly movement of the right buttock member. Thus, for a cyclist's comfort, the seat pad 20 should be flexible enough to follow the buttock movements.
As shown in
In an embodiment, the padded areas 36 in the seat surfaces 28 have a length along the longitudinal axis A-A of the seat pad 20 and the elongated groove 30 extends past a middle point of the padded area length, towards the intermediate portion 26.
In the embodiment shown in
In an embodiment, the fabric piece 52 is made of material(s) different than materials of the top, middle, and bottom fabric layers 62, 63, 64 of the seat pad 20.
In an embodiment, a rear end 56 (or peripheral edge) of the fabric piece 52, in continuation with the peripheral edge of the seat pad 20, is attached to the edge of cycling garment 68 in which the seat pad 20 is mounted and the two opposed inner edges 54 defining the groove 30 and adjacent and corresponding lateral edges of the fabric piece 52 are not attached to the cycling garment 68, i.e. they can move relatively to the cycling garment 68. In the embodiment shown, the rear end 56 of the fabric piece 52 is stitched to the cycling garment 68. In an alternative embodiment, the inner edges 54 of the seat pad 20 and/or the lateral edges of the fabric piece 52 can also be stitched to the cycling garment 68. It is appreciated that in an alternative embodiment, the rear end 56 and the inner edges 54 of the seat pad 20 and/or the lateral edges of the fabric piece 52 can be attached to the cycling garment 68. In another alternative embodiment, only the inner edges 54 of the seat pad 20 and/or the lateral edges of the fabric piece 52 can be attached to the cycling garment 68.
Referring now to
In an embodiment (not shown), sew lines extend through the seat pad 120 and the cycling garment 68 along the inner edges 154. In an alternative embodiment, the sew line(s) that extend(s) along the peripheral edge of the seat pad 120 ends at a rear end of the groove 30 and the inner edges 154 are not sewed to the cycling garment 68.
The seat pad 20, 120, 220 further includes aeration windows 58, 158, 258 defined in the front portion 22, 122, 222. In the embodiment shown, the aeration window 58, 158, 258 exposes a piece of mesh material 60, 160 having perforations therein for an increased air and moisture exchange between the cyclist's side of the seat pad 20, 120, 220 and an opposite outer side and vice versa.
Mesh material 60, 160 is a synthetic or fabric-like perforated flexible material which perforation units are each of a size and shape enabling free bodily heat release and free humidity escape therethrough. Furthermore, mesh material is usually a relatively elastic fabric.
It is appreciated that, in an alternative embodiment (not shown), the aeration window 58, 158, 258 can be free of any material, i.e. it exposes the cycling garment 68 when mounted thereto, or it can expose any other fabric.
In alternative embodiments (not shown), the seat pad 20, 120 may include other perforations or aeration windows which extend entirely therethrough to provide ventilation during use of the seat pad 20, 120. Such ventilation allows airflow to move from the cyclist's side of the seat pad 20, 120 to an opposite outer side and vice versa. This airflow cools the cyclist and allows fluid evaporation to thus keep the cyclist dry for enhanced comfort. Furthermore, the perforations and aeration windows are sized and disposed to allow the passage of fluid, that is, perspiration, rainwater, etc., which has accumulated on the seat pad 20, 120 against the cyclist's body, and which is permitted to drain from the cyclist's side of the pad to the outer, exterior side. The seat pad 20, 120 is typically disposed in a cycling pant formed of a moisture wicking material. Thus, the fluid which drains through the perforations and aeration windows to the outer side of the pad is promptly wicked to an exterior of the pant away from the cyclist's body. This provides enhanced comfort and dryness. Additionally, the perforations and aeration windows reduce the overall weight of the seat pad 20, 120 and provide increased flexibility thereof, thus enhancing comfort to the cyclist. The perforations may include a recess, i.e. a generally planar surface of a reduced thickness relative to the remainder of the padded areas.

In the embodiment shown in
In an embodiment, the fabric piece 252 is made of material(s) different than materials of the top, middle, and bottom fabric layers 262, 263, 264 of the seat pad 220.
In an embodiment, a front end (or peripheral edge) of the fabric piece 252, in continuation with the peripheral edge of the seat pad 220, can be secured to a cycling garment (not shown) in which the seat pad 220 is mounted and the two opposed inner edges 254 defining the groove 270 and adjacent and corresponding lateral edges of the fabric piece 252 are not attached to the cycling garment, i.e. they can move relatively to the cycling garment. In the embodiment shown, the front end of the fabric piece 252 is stitched to the cycling garment. In an alternative embodiment, the inner edges 254 of the seat pad 220 and/or the lateral edges of the fabric piece 252 can also be stitched to the cycling garment. It is appreciated that in an alternative embodiment, the front end and the inner edges 254 of the seat pad 220 and/or the lateral edges of the fabric piece 252 can be attached to the cycling garment. In another alternative embodiment, only the inner edges 254 can be secured to the cycling garment, or any combinations thereof.
In an alternative embodiment (not shown), the elongated groove 270 can be free of any material extending between its two opposed inner edges 254, i.e. the two inner edges 254 are not connected. The inner edges 254 of the seat pad 220 may or may not be attached, for instance stitched, to the cycling garment to which the seat pad 220 is mounted.
It is appreciated that combinations of the above-described seat pads 20, 120, 220 can be made. For instance and without being limitative, a seat pad can include one or several front and rear elongated grooves 30, 130, 230, 270, with or without a fabric piece 252 extending therein. It can also include aeration windows 58, 158, 258.
The seat pad 20, in one embodiment, is secured to the cycling garment 68 as shown in
When the seat pad 20 is mounted to the cycling garment 68, the inner edges 54 defining the groove 30 and/or the rear end 56 may or may not be secured to the cycling garment 68.
It is appreciated that the design of the seat pad 20, 120, including the shape, position, and thickness of the padded areas, can differ from the above described and illustrated embodiments. The design of the seat pad can be adapted to the cyclist's gender and anatomy. For instance and without being limitative, a female seat pad is generally thinner and smaller than a male seat pad.
The seat pad has been generally described herein as being a member mounted within a pant to be worn by a cyclist, etc. Alternatively, however, the construction of the seat pad may be formed integrally within the pant. That is, it is not required that the seat pad be an element separate from the pant. The pad and its unique features may be formed integrally within the material forming the pant.
While the invention has been described with reference to an exemplary embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
