Materials or elements that impart padding or cushioning (i.e., that attenuate impact forces) are commonly incorporated into a variety of products. Athletic apparel, for example, often incorporates pads that protect the wearer from contact with other athletes, equipment, or the ground. More specifically, pads used in American football and hockey provide impact protection to various parts of a wearer. Helmets utilized during bicycling, skiing, snowboarding, and skateboarding incorporate pads that provide head protection during falls or crashes. Similarly, gloves utilized in soccer (e.g., by goalies) and hockey incorporate pads that provide protection to the hands of a wearer. In addition to apparel, mats (e.g., for yoga or camping), chair cushions, and backpacks all incorporate pads to enhance comfort.

The advantages and features of novelty characterizing aspects of the invention are pointed out with particularity in the appended claims. To gain an improved understanding of the advantages and features of novelty, however, reference may be made to the following descriptive matter and accompanying figures that describe and illustrate various configurations and concepts related to the invention.
The foregoing Summary and the following Detailed Description will be better understood when read in conjunction with the accompanying figures.
The following discussion and accompanying figures disclose various configurations of a pad element 10 that may be incorporated into a variety of products, including articles of apparel, mats, seat cushions, and backpacks, for example.
General Pad Element Configuration
With reference to
A variety of materials may be utilized for the various components of pad element 10. Base member 20 may be formed from generally compressible materials, such as polymer foam materials, that return to an original shape after being compressed. Examples of suitable polymer foam materials for base member 20 include polyurethane, ethylvinylacetate, polyester, polypropylene, and polyethylene foams. Cover layers 31 and 32 may be formed from knitted, woven, or non-woven textile elements that include rayon, nylon, polyester, polyacrylic, cotton, wool, or silk, for example. In some configurations of pad element 10, one or both of cover layers 31 and 32 may be formed from a polymer sheet. Insert elements 40 are substantially spherically shaped and may also be formed from generally compressible materials, such as the polymer foam materials discussed above for base member 20.
The compressible polymer foam materials forming base member 20 and insert elements 40 attenuate impact forces that compress or otherwise contact pad 10. When incorporated into an article of apparel, for example, the polymer foam materials of base member 20 and insert elements 40 may compress to protect a wearer from contact with other athletes, equipment, or the ground. Accordingly, pad element 10 may be utilized to provide cushioning or protection to areas of a wearer that are covered by pad element 10.
Referring to
As depicted in
Referring to
In addition to attenuating impact forces, pad element 10 has an advantage of simultaneously providing one or more of breathability, flexibility, a relatively low overall mass, and launderability. When incorporated into an article of apparel, particularly apparel used for athletic activities, a wearer may perspire and generate excess heat. By (a) forming apertures 23 in base member 20, (b) utilizing a permeable textile material for cover layers 31 and 32, and (c) locating insert elements 40 within apertures 23, areas for air to enter the apparel and for moisture to exit the apparel are formed through pad element 10. More particularly, air and moisture may pass through cover layers 31 and 32, through apertures 23, and around insert elements 40 to impart breathability to areas of the apparel having pad element 10.
In addition, a difference in dimension between insert elements 40 and base member 20 may facilitate the formation of one or more gaps between portions of pad element 10 and a surface against which pad element 10 rests. For example, by forming insert elements 40 to have a greater height than a height of apertures 23 and a thickness of base member 20, insert elements 40 may essentially hold portions of pad element 10 away from the body of the wearer, creating one or more gaps between pad element 10 and the body of the wearer. Air passing through cover layers 31 and 32, through apertures 23, and around insert elements 40 may then flow through the gaps between pad element 10 and the body of the wearer to further enhance the breathability of the apparel having pad element 10.
Moreover, the materials discussed above for the components of pad element 10 impart flexibility and a low overall mass to pad 10. Furthermore, the presence of apertures 23 and the configuration of insert elements 40 permit pad element 10 to be laundered without significant shrinkage or warping, even when temperatures associated with commercial laundering processes are utilized. Accordingly, pad element 10 may simultaneously provide impact force attenuation, breathability, flexibility, a relatively low overall mass, and launderability to an article of apparel.
Manufacturing Processes
A variety of techniques may be utilized to manufacture pad element 10. With reference to
Once cover layer 32 is secured to base member 20, insert elements 40 are located within apertures 23, as depicted in
Following the placement of insert elements 40 within apertures 23, cover layer 31 is positioned relative to base member 20 and proximal to first surface 21, as depicted in
Pad Element Variations
Aspects of pad element 10 may vary, depending upon the intended use for pad element 10 and the product in which pad element 10 is incorporated. Moreover, changes to the dimensions, shapes, and materials utilized within pad element 10 may vary the overall properties of pad element 10. That is, by changing the dimensions, shapes, and materials utilized within pad element 10, the compressibility, impact force attenuation, breathability, flexibility, and overall mass of pad element 10 may be tailored to specific purposes or products. Many variations for pad element 10 are discussed below. Any of these variations, as well as combinations of these variations, may be utilized to tailor the properties of pad element 10 to an intended use or particular product.
Whereas pad element 10 is depicted in
Referring to
Base member 20 and surfaces 21 and 22 are depicted in
In the configurations discussed above, inset elements 40 are substantially spherical, are narrower than apertures 23, and are taller than apertures 23. An advantage to such configurations of insert elements 40 and apertures 23 is that insert elements 40 may facilitate the formation of one or more gaps between pad element 10 and a surface against which pad element 10 rests to further enhance the breathability of an article of apparel having pad element 10.
In other configurations, however, the dimensions of apertures 23 and insert elements 40 may vary. Accordingly, the impact force attenuation characteristics of pad element 10 may vary across pad element 10. For example, the thickness of base member 20 may vary, and height dimension 41 of apertures 23 may correspondingly vary. Referring to
Varying the dimensions of apertures 23 and insert elements 40 may impart a contour to pad element 10. In some configurations, the dimensions of apertures 23 and insert elements 40 may vary in a manner corresponding with each other. For example, referring to
In some configurations, insert elements 40 may have shapes other than a substantially spherical shape. For example, referring to
In some configurations, apertures 23 may have non-rectangular cross-sections. Any of height dimension 41, width dimension 42, or depth dimension 43 may vary within an aperture 23. For example, referring to
In the configurations discussed above, pad element 10 is typically depicted as resting on a substantially planar and rigid surface. Accordingly, the configuration of cover layer 32 is depicted as substantially planar, while the configuration of cover layer 31 is depicted as varying in accordance with the sizes and shapes of the underlying insert elements 40. In configurations in which cover layer 32 is formed of a relatively rigid material, such as some configurations in which cover layer 32 is formed from a polymer sheet, the configuration of cover layer 32 may also be substantially planar, while the configuration of cover layer 31 varies corresponding with the underlying insert elements 40.
In other configurations, when pad element 10 is not resting on a substantially planar and rigid surface and when cover layer 32 is not formed of a relatively rigid material, the configuration of cover layers 31 and 32 may vary. In configurations in which both cover layers 31 and 32 are formed of a somewhat flexible material, the configurations of both cover layers 31 and 32 may vary in accordance with the sizes and shapes of insert elements 40. Accordingly, the creation of one or more gaps between pad element 10 and the body of a wearer may be enhanced. For example, with reference to
Additionally, in some configurations, any of the variations discussed above may be combined. That is, any of the dimensions of apertures 23 and insert elements 40, a contour of pad element 10, a shape or configuration of insert elements 40, a cross-sectional configuration of apertures 23, or a rigidity of cover layers 31 and 32, or any combination thereof, may vary across pad element 10.
In the configurations discussed above, insert elements 40 are formed from generally compressible materials, such as the polymer foam materials discussed above for base member 20. In other configurations, insert elements 40 may be formed from other materials. For example, insert elements 40 may be formed of a rubber material, a non-foamed polymer material, a wood material, a textile material, a ceramic material, a metal material, or a composite material. Alternatively, insert elements 40 may be formed of a combination of any of the above-described materials. For example, insert elements 40 may have a non-foamed polymer core with a rubber coating.
Insert elements 40 may be formed to have a solid configuration. Alternatively, insert elements 40 may be formed to have other than a solid configuration. For example, referring to
Additionally, the material forming insert elements 40 within one particular aperture 23 may be different than the material forming insert elements 40 within another particular aperture 23, or insert elements 40 within one aperture may be formed from two or more types of material.
Although cover layers 31 and 32 may have the general shape and size of surfaces 21 and 22, cover layers 31 and 32 may also extend beyond the edges of surfaces 21 and 22. Referring to
The arrangement of apertures 23 may have an effect upon various properties of pad element 10, including durability, breathability, and compressibility, for example. In the configuration depicted in
In addition to spacing between apertures 23, the shapes of apertures 23 may vary. Whereas apertures 23 are depicted as having circular shapes in
Any of the various configurations of pad element 10 discussed above, or combinations of the configurations, may be utilized to tune or otherwise engineer the properties of pad element 10. By varying a curvature or contour imparted to pad element 10, the dimensions or shape of apertures 23, the spacing between apertures 23, the dimensions, shape or configuration of insert elements 40, the rigidity of cover layers 31 and 32, the materials forming base member 20 and insert elements 40, or the thickness of base member 20, for example, the properties of pad element 10 may be adjusted to suit particular uses or products. Moreover, the properties of pad element 10 may vary within a single pad element 10. That is, one area of pad element 10 may have different properties than another area of pad element 10 by varying a curvature or contour imparted to pad element 10, the dimensions or shape of apertures 23, the spacing between apertures 23, the dimensions, shape or configuration of insert elements 40, the rigidity of cover layers 31 and 32, the materials forming base member 20 and insert elements 40, or the thickness of base member 20, for example, between the two areas. Accordingly, a variety of modifications may be made to pad element 10 in order to tune or otherwise engineer the properties of pad element 10 for particular uses or products.
Product Configurations
Different configurations of pad element 10 that may be incorporated into a variety of products, including articles of apparel, mats, seat cushions, and backpacks, for example. Referring to
A variety of techniques may be utilized to incorporate pad elements 10 into shirt 51. As an example, pad elements 10 may be stitched or otherwise bonded to materials forming shirt 51. In some configurations, pad element 10 may have the configuration depicted in
Shirt 51 may be intended for use as a compression garment. In addition to therapeutic uses, compression garments are often worn by athletes as a base layer under jerseys or other athletic apparel. In general, compression garments or other garments intended as base layers (a) exhibit a relatively tight fit that lays adjacent to the skin of the wearer and (b) stretch to conform with the contours of the wearer. While the textile materials forming compression garments may have one-directional stretch of, for example, more than ten percent prior to tensile failure, the textile materials forming other compression garments have two-directional stretch of at least thirty percent prior to tensile failure. Accordingly, when shirt 51 is formed to have a relatively tight fit and to stretch to conform to the contours of the wearer, the textile materials forming shirt 51 may have two-directional stretch of at least thirty percent prior to tensile failure. Moreover, an advantage to forming shirt 51 to be a compression garment is that pad elements 10 are located immediately adjacent to the skin of the wearer and the tighter materials cause pad elements 10 to flex to the shape of the wearer.
In addition to being located in elbow regions of a garment, pad elements 10 may also be located in other areas. Referring to
Referring to
In addition to shirt-type garments and pants-type garments, pad elements 10 may be incorporated into garments that cover other areas of the wearer, such as hats, helmets, wraps, footwear, socks, and gloves, for example. As an example, a wrap 55 having one pad element 10 is depicted in
Pad elements 10 may also be utilized in products other than apparel. Referring to
