Description




TECHNICAL FIELD




The present inventions relates generally to a seating device, and more specifically, the present invention relates to a body cushion which is specially contoured for a person's body and which is particularly suited for use in a variety of sporting applications.




BACKGROUND OF THE INVENTION




Over the years, it has been increasingly popular to use a portable seat cushion for support and comfort while attending and viewing sporting events in a stadium or the like, and these same seat cushions are also used by participants of sports which require prolonged periods of sitting. For example and as is known, the sports of fishing and gamesmanship (i.e., hunting), generally require the participant to sit in a set location for prolonged periods of time. Typically, this location comprises a metal seating area in a boat or a seating area in a hunting structure designed to protect and camouflage the individual from the game which is being sought. As such, the posterior of the individual is likely to become very sore by sitting on a hard surface for prolonged periods of time.




To alleviate the discomfort caused by sitting on these hard surfaces, it is common for an individual to bring a seat cushion, commonly referred to as a stadium seat. The seat cushion typically has a plastic outer coating surrounding a cushion material disposed therein. Air holes are provided in the outer coating to permit air to escape as the individual sits on the pad and the seat cushion contracts, thereby forcing air out from the center thereof. Usually, a pair of side straps are formed with and extend from the outer coating. These side straps permit the user to easily carry the seat cushion and place it in a desired location on the hard seating surface. The seat cushion is typically in the shape of a rectangle.




While the conventional seating cushions of the prior art are suitable for some uses, they suffer from the disadvantage that the seating cushions are generally not contoured to the user's body for providing extra comfort and more importantly, the seating cushions are designed to be carried by the user and then placed on the hard seating surface as the user sits down. Consequently, if the user decides to move positions or slightly rise to observe an event or an object, the seating cushion is free to become displaced from its original setting. In addition, external conditions, such as wind, can cause the seat cushion to become misplaced. This causes difficulties when the user is involved in a sport such as fishing or hunting because the user does not have much time to continually observe the position of the seating cushion as the user sits back down on the seating surface. It is desirable for a hunter or fishing participant to be able to rise from the seating surface, conduct a series of movements and then sit back down without having to worry about the location of the seating cushion.




Thus, it can be seen that it would be advantageous to have a seating cushion which is body contoured and permits the user to move without worry.




SUMMARY OF THE INVENTION




The above-discussed and other drawbacks and deficiencies of the prior art are overcome or alleviated by the body cushion of the present invention. The body cushion comprises a posterior portion to accommodate the posterior of a user and a pair of leg extensions which extend therefrom. According to the present invention, the posterior portion and the leg extensions are preferably contoured to the shape of the user's body so that a secure fit results when the user wears the body cushion. The body cushion is designed to be secured to the lower half of the user's body by a number of fastening devices, e.g, interlockable belts, which are disposed in the body cushion.




More specifically, a waist belt is provided at a topmost end of the posterior portion and a leg belt is provided at the bottommost end of the leg extension. The leg extensions are preferably integrally formed with the posterior portion, and in a preferred embodiment, the body cushion is formed of a closed cell foam by known processes. The posterior portion seats against the buttocks area of the user and the leg extensions seat against the backside of the user's legs.




The leg extensions include pleated portions which easily extend to permit movement of the user and to provide extended comfort and protection when the user sits down a hard seating surface with the body cushion securely affixed to the user's posterior and to the backside of the user's legs.

DESCRIPTION OF THE PREFERRED EMBODIMENT:




Referring to

FIGS. 1-3

and

FIG. 6

, a body cushion or seat cushion is illustrated and generally indicated at


10


. Body cushion


10


includes a central posterior portion


12


having a first end


14


and an opposite second end


16


, with first end


14


being generally positioned around the waist of a user when body cushion


10


is properly worn by the user. At first end


14


, a plurality of slots


18


are formed in body cushion


10


for receiving a waist fastener


20


. Waist fastener


20


is preferably an adjustable belt formed of a known material. For example and as shown in

FIG. 7

, a polyweb belt


20


having an adjustable side interlocking buckle assembly


22


is suitable for use in the present invention. Waist fastener


20


is designed to slidingly fit within the plurality of slots


18


so that the user may easily adjust fastener


20


and interlock buckle assembly


22


so as to secure first end


14


around the user's waist. Another aspect of waist fastener


20


is that it is designed to hold common accessories, such as knifes, flash lights, canteens, fanny packs, etc., by sliding one of these items along waist fastener


20


, which is preferably a polyweb belt.




Posterior portion


12


is slightly arcuate in nature, as best shown in

FIG. 1

, so that body cushion


10


is contoured to fit the natural shape of the user's body. More specifically, posterior portion


12


has wrap around sides


24


which extend upward in a slightly arcuate manner so that wrap around sides


24


snugly secure the body of the user within body cushion


10


. In other words, by providing a snug fit, body cushion


10


eliminates the likelihood that posterior portion


12


will freely ride along the posterior of the user.




Posterior portion


12


has an outer surface


30


and an inner surface


32


. During use, inner surface


30


is in contact with the posterior of the user and outer surface


32


faces outward from the posterior and when the user sits, outer surface


32


will contact the seating surface. Formed within outer surface


32


is a plurality of ribs


34


which reduce slipping of body cushion


10


on the seating surface when the user sits down and/or moves along the seating surface.




In accordance with the present invention, a pair of leg extensions


40


extend from posterior portion


12


and are designed to be securely positioned around the backside of each of the user's legs just above the knee. Preferably, leg extensions


40


are integrally formed with posterior portion


12


, as will be described in further detail hereinafter. Each of leg extensions


40


has a first end


42


and an opposite second end


44


, wherein first end


42


is preferably integral with second end


16


of posterior portion


12


and second end


44


is positioned proximate the knee on the back side of the user's legs. Leg extensions


40


are also slightly arcuate in nature and include wrap around sides


46


which position and properly locate the user's legs within leg extensions


40


. In an exemplary embodiment, each of leg extensions


40


is approximately 10 inches in length. It being understood that this length is merely exemplary in nature and that the length of leg extensions


40


may be either increased or decreased accordingly.




In one aspect of the present invention, each of leg extensions


40


includes a pleated portion


48


and a lower portion


50


which is generally below the pleated portion


48


. Pleated portion


48


comprises a plurality of pleats formed in leg extension


40


. In an exemplary embodiment, pleated portion


48


has a normal length of approximately 6 inches and in a retracted state, pleated portion


48


extends to a length of approximately 9 inches, thus leg extension


40


is capable of extending to accommodate the movement of the user who is wearing body cushion


10


. Thus, normal stretching movements which are likely encountered during movement (e.g, sitting motion, walking motion, and the like) of the user with the body cushion


10


attached to the posterior portion of the user is accommodated by the extendable pleated portion


48


.




Lower portion


50


is the part of the leg extension


40


which extends below pleated portion


40


in a direction away from posterior portion


12


. In a preferred embodiment, lower portion


50


does not include the plurality of pleats but instead is slightly arcuate in shape so that it is contoured to the natural shape of the legs of the user. Preferably, lower portion


50


is approximately 4 inches in length and has a thickness of about ¾ inch.




In addition, lower portion


50


also includes a plurality of slots


52


which receive a leg fastener


60


on each of the user's legs. Leg fastener


60


is preferably an adjustable belt formed of a known material. In a preferred embodiment, leg fastener


60


comprises the polyweb belt


20


shown in FIG.


7


. In the embodiment, polyweb belt

60


is designed to slidingly fit within the plurality of slots


52


so that the user may easily adjust fastener


60


and the interlock buckle assembly so as to secure lower portion


50


of leg extension


60


around the user's leg.




Accordingly, in a preferred embodiment, leg extensions


40


can cover, in an extended state, approximately 13 inches of the back side of the user's legs. This advantageously provides comfort and protection of the back side of the user's legs when the user is sitting on a hard seating surface, such as metal bleacher type area.




As best shown in

FIG. 2

, leg extensions


40


have a slight taper so that the topmost portion


41


of leg extension


40


is wider than the width of the bottommost portion


43


of leg extension


40


. In one embodiment, topmost portion


41


has a width of about 8 inches and bottom most portion


43


has a width of about 7 inches. It being understood that these dimensions are merely exemplary in nature.




Preferably and in one embodiment, posterior portion


12


has a length of about 13 inches and a width of about 18 inches. Consequently, in a non-extended state, the over all length of body cushion


10


is about 23 inches.




As best shown in

FIG. 6

, posterior portion


12


is slightly recessed between first end


14


and second end


16


. This recessed area


70


is intended to accommodate the posterior of the user, while still providing a body contoured fit to the user's waist at first end


14


and a body contoured fit to the user's lower posterior area where one's legs join the buttocks. As best seen in

86


.




Body cushion


10


may be formed of a number of known materials by known processes. In an exemplary and preferred embodiment, body cushion


10


is formed of a polyvinyl chloride material using a high pressure molding process. As is known in the art, high pressure molding involves heating the material to liquid form and then injecting it into a mold. In the mold, the material expands to form body cushion


10


and then it is removed from the mold and allowed to cool. This process allows body cushion


10


to be formed in a variety of colors and thicknesses depending upon the end use and desired characteristics.




In another embodiment, body cushion


10


is formed from closed cell foams, i.e., sheet foams, using a thermal mold process. As is known, the material is initially provided in the form of sheets and it is then placed in a hot mold and is thermal molded to form body cushion


10


. The foam sheets come in a variety of densities and colors, which allows the manufacturer to tailor the performance and appearance of the body cushion


10


. The density of the material determines the thickness which is required. One conventional, closed cell foam is a neoprene foam. It is understood that the above-recited materials and processes are mentioned for purpose of illustration and it is within the scope of the present invention that other conventional processes and materials may be used.




While preferred embodiments have been shown and described, various modifications and substitutions may be made hereto without departing from the spirit and scope of the present invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.
