1. Field of the Invention
The invention relates to padded garments and particularly relates to a garment having padding made up of energy dissipating conformable padding attached thereto.
2. Description of Related Art
In many activities padding worn by a user acts to absorb energy from a sudden impact. Such a sudden impact occurs in activities ranging from sporting activities where frequent contact is likely to vocational activities where contact is less likely, but nevertheless a very real possibility. As examples, sporting activities, to name a few, may include football, soccer, hockey, baseball, rugby and basketball while one such vocational activity may be, for example, that of a tradesman. An additional sporting activity includes race car driving, whereby the driver experiences impact transmitted from the car frame.
However, even when such padding is employed, depending upon the manner and degree to which the padding conforms to the user's body and the energy dissipating characteristics of the conformal padding material, the force from a sudden impact, which may be vibrational, may not be distributed over the area of the padding. For example, if the padding is made of a hard shell and contacts only a protriding bone, all of the force of impact may be transmitted to that bone. Even when the padding is not associated with a hard shell, if it nevertheless does not conform to the user's body and exhibit desired energy dissipation characteristics, then once again it is possible the energy from a sudden impact may not be distributed over the area of the padding but concentrated in a smaller area.
For providing a clearer explanation of the effect in response to sudden impact when hard shell padding is used, football shoulder pads will hereinafter be discussed with the understanding that the scope of this application should in no way be limited to such shoulder pads, or hard shell padding in general, but may be extended to padding used for body protection in a wide range of activities.
Directing attention to football shoulder pads, a set of shoulder pads may protect a football player from the force of a sudden impact upon the shoulder pads by distributing that force across a wider area on the body of the football player. Although many shoulder pads have a high level of adjustability, nevertheless due to the variation in shape inherent in the bodies of individuals, the contact areas and the degree of contact between the shoulder pads and the football player's body are irregular, thereby resulting in an uneven distribution of forces through the shoulder pad to the body of the player. In a worse case scenario, the shoulder pads are supported primarily by the clavicle bone and any downward force upon the shoulder pads is transmitted to the player entirely by a concentrated force upon the clavicle bone. Some shoulder pads include a protective ring around the clavicle such that forces are transmitted through this protective ring. However, even under these circumstances, there is an imperfect mating between the shoulder pads and the body of the football player such that transmission of forces produced by sudden impact upon the shoulder pads is transmitted to the player in an irregular pattern depending, first of all, on the existence of contact between the shoulder pads and the player and, second of all, on the degree to which such contact provides support. It is possible that with this irregular contact certain contact areas will absorb a greater amount of the force from sudden impact than others.
Athletic trainers frequently customize the fit and impact protection of shoulder pads by securing resilient padding to the interior of the shoulder pads in an attempt to provide a more uniform contact between the shoulder pads and the player. However, securing such padding to the inside surface of the shoulder pads may be difficult.
Furthermore, such padding ideally will follow the contour of the player's body. However, even with such padding, the force exerted upon the shoulder of the player may be uneven.
A conformal, energy dissipating padding design is needed to provide relatively uniform contact between hard shell padding and its wearer such that forces produced by sudden impact may be more effectively dissipated.
Again, while this scenario has been directed to football shoulder pads, this same problem exists with protective equipment used in many other sports including soccer, hockey, baseball, rugby and basketball.
In a separate scenario, the uniforms in many sporting activities are not intended to accommodate any padding and, furthermore, over time, a distaste on behalf of the fans and the players has developed toward the use of padding with such uniforms. However, in contact sports, such as, for example, rugby and soccer, it is believed that padding may be embraced by the players but only to the extent that such padding does not substantially change the appearance of the uniform and to the extent that such padding does not inhibit their movement.
Therefore, a need exists for padding that is conformal to the body surface it contacts and dissipates the energy of a sudden impact to participants in sports activities.
A garment has a piece of clothing with at least one pad of energy dissipating conformal media. The pad is positioned at a location on the clothing to diminish the effect of a sudden impact upon a wearer of the garment. Depending upon the application, this garment may be utilized in conjunction with hard shell padding or may be used alone without hard shell padding. In one embodiment a connector is attached to the surface of the clothing for securing the at least one pad of media to the clothing.
A system for more uniformly distributing the forces of sudden impact upon hard shell padding has a garment comprised of clothing worn by a wearer and hard shell padding placed over the garment to protect a portion or portions of the body of the wearer, wherein the hard shell padding does not conform entirely to the wearer's body such that the force imparted to the wearer's body through sudden impact is concentrated at the points of contact between the padding and the body of the wearer. To compensate for this, the system also includes at least one pad of energy dissipating conformal media secured at a location on the clothing between the wearer's body and the hard shell padding. The pad conforms between the hard shell padding and the wearer's body such that the force of a sudden impact upon the hard shell padding causes the pad to uniformly distribute the force of impact over the area of the pad in contact with the hard shell padding and the wearer's body.
The padding material is a light weight, viscoelastic polymer that exhibits fluid-like characteristics in the absence of a sudden impact, and acts as a solid when subjected to a sudden impact. Polyborosiloxane is a preferred polymer material.
A padded garment in accordance with the invention may likewise be produced for use by race car drivers to provide both conformal contact between the driver and the seat and energy dissipating response to sudden impact.
As will now be discussed, a pad 20 may have different configurations and may be secured to the clothing 15 in a variety of different ways. Directing attention to

As furthermore illustrated in
Depending upon the particular application, the pad discussed herein may be used in conjunction with hard shell padding or may be used alone without hard shell padding.
Additionally, a garment in accordance with the subject invention may be utilized by race car drivers and, under such circumstances, the garments may include padding in the areas of contact between the driver and the driver's seat. Typical areas of contact between the driver and the driver seat include the buttocks, tailbone, hip and torso regions. As a result, a garment for such a driver could be an elongated shirt, a pair of pants or a jumpsuit and would include a portion around the waist, hip, buttocks and tailbone regions that would provide such padding.
The media and associated pads have so far been discussed in the context of dissipating energy. However, the media is a flowable conformable material and, for that reason, provides additional benefits to a user. In particular, directing attention to
In accordance with the subject invention,
The use of such pads may also be applied to other hard shell padding such as a shin guard, wherein the clothing is a sock and the pad is secured to the clothing between the shin guard and the shin of the user. Additionally, the hard shell padding may be a forearm guard and the clothing may be a shirt, wherein the pad is secured to the clothing 15 between the forearm guard and the forearm of the user. Furthermore, under certain conditions, the pad may be secured to clothing for use without a hard shell padding. For example, it is possible that under certain circumstances shin guards may have only the pad secured directly to a sock or sleeve positioned about the shin of the wearer without a hard shell padding.
A typical pad may be made of a polyurethane encasement that is vacuum molded against a polyurethane substrate around the media. The encasement may also be made of urethane, PVC, nylon or neoprene. While the media is somewhat fluid and easily conforms to different shapes to maximize the benefits of this conformability, it is necessary for the encasement to be pliable. Therefore, the encasement may be a layer of polyurethane of less than 1 mil. One type of polyurethane that may be utilized is polyether aromatic polyurethane such as Stevens Polyurethane ST-1880-87 provided by the Stevens Urethane Company.
It is also possible to produce an encasement around the pad by dipping the pad into an encasement fluid, such as a vinyl solution.
It is also possible to surround the media in an encasement made of cloth woven sufficiently tightly to prevent permeation of the media therethrough.
What has so far been discussed, is an energy dissipating garment having a piece of clothing with at least one pad with at least one pad of energy dissipating conformal media, wherein the at least one pad is secured to the clothing utilizing an intermediate connector. Since a typical pad may be made of a polyurethane encasement, it is possible to weld the pad directly to the garment. Directing attention to
