Description
Background of the Invention
1. Field of the Invention
The present invention relates to portable seats, and more particularly pertains to inflatable seat cushions attached to the waist of the user by means of a storage pouch with belt with the seat cushion removably attached to the pouch using VELCRO. The inflatable seat cushion of this invention is designed to be used by people who would like the comfort of a padded cushion and the convenience of not having to carry this cushion with their hands. When desired by the user, manufacture, or retailer the seat cushion can have personalized messages applied to the cushion or to the slip cover which can be applied over the seat cushion. When the user is standing up, the cushion, hanging from the users waist, will display the message.
2. Description of the Prior Art
By way of example, the prior art discloses in U.S. Pat. No. 4,781,413 to Shumack a Portable Stadium Seat for use over existing bleachers or stadium seats that has a rigid frame on which an inflatable cushion is provided.
U.S. Pat. No. 4,592,589 to Hellwig discloses a inflatable seat cushion intended as a training or helping device mainly for sitting upright without a back rest.
U.S. Pat. No. 3,994,529 to Lippert discloses a stadium chair assembly with pivotal legs and at least one pivotal holder located to swing downwardly to return the chair to a stadium bench with the legs folded up under the seat.
U.S. Pat. No. 5,516,193 to Simpson discloses a portable stadium seat apparatus with a back rest used in spectator events where the seating is flat benches without backs.
In this respect, the inflatable portable seat cushion with pouch according to the present invention substantially departs over current products of it's type because current inflatable seating products are large and cumbersome and need to be carried in a persons hand. Other portable padded seating products are made with fillers that do not collapse small enough to fit into a pocket or pouch.
Summary of the Invention
In view of the disadvantages described in the prior art, the inflatable portable seat cushion of this invention overcomes many of the disadvantages of portable seating and has many applications other than just stadium seating.
The inflatable seat cushion is made from flexible, air tight, durable, materials formed to a square, oblong, round, or any other shape as would be preferred to any manufacture or consumer. Attached to the back and top edge of the seat cushion is a material strip or backing which has a VELCRO strip located at the top that would allow the cushion to be removably secured to the bottom of the pouch which is can be attached around a persons waist. To protect the seat cushion from dirt and damage, the seat cushion can be placed inside a slip cover. The slip cover is attached to the back of the cushion using common snap type fasteners or VELCRO. To add style to the slip cover, the slip cover can be used to advertise the consumers favorite athletic teams, business, logos, or any other form of advertising.
Located at the back or top edge of the seat cushion is an inflation tube and cap used to inflate the cushion, or a small hand pump with control valve. Located inside the cushion, attached to the inside upper portion, may be lightweight, flexible heating elements that are controlled by common batteries and an on/off switch. Manufactured into the center at various locations are indentations that allow the upper portion of the cushion to be attached to the lower portion of the cushion. This is to allow the seat cushion to keep its shape and form as determined by the manufacture.
To inflate the seat cushion using the hand pump, first the air control valve would be set in the closed position. Next, with hand pressure applied to the bulb pump, air is forced into the cushion until the firmness of the cushion is to the consumers liking. To deflate the cushion, simply turn the air control valve to the open position and allow the air to escape. To inflate cushion using the inflation tube, simply blow into inflation tube until desired firmness is achieved, than install the air cap into inflation tube. To deflate the cushion, simply remove the cap and allow the air to excape. The seat cushion can than be rolled up and stored in the pouch for protection and latter use.
The pouch in which the cushion may be stored is made from light weight water proof material and is formed to fit comfortably around a persons waist. Attached to the pouch is a belt and belt buckle used to hold the pouch in place while on a persons waist. The pouch can be made with many separate compartments of various sizes, but most importantly, the compartment located at the bottom of the pouch is to be large enough to hold and store the seat cushion. Located inside the bottom compartment is a Velcro strip used to hold the seat cushion removably in place. Located below the VELCRO strip is a zipper used to close the compartment when the deflated seat cushion is stored.
It is to be understood that the invention is not limited in its application to the details of the construction and to the arrangements of the members set forth in the following description or illustrations. It is also understood that those familiar with the manufacture and or methods of construction of the present invention or its members, may readily be utilized as a basis for the designing of other shapes, methods, and systems for carrying out the purpose of the present invention. It is important that the claims be regarded as including such similar construction insofar as they do not depart from the spirit and scope of the present invention.
