Seat cushion
A seat cushion includes a flexible body and a plurality of spacing members. The flexible body has a seating surface and a support surface spaced apart from the seating surface. The seating surface has a first area and the support surface has a second area. The plurality of spacing members are spaced apart and distributed across the second area, with each of the plurality of spacing members extending outwardly in a first direction from the support surface.
The present invention relates to human seating comfort, and, more particularly, to a seat cushion.
BACKGROUND OF THE INVENTIONSporting and entertainment facilities typically provide seating areas including one or more sections of solid surface seating, such as benches or bleachers, that are hard and uncomfortable to sit on for extended seating periods. Such solid surface seating, for example, may be made from metal or wood, and may be thermally conductive. Accordingly, on particularly hot or cold days, for example, such benches or bleachers may add to seating discomfort by transmitting the cold or heat directly to a person's posterior.
Attempts have been made to reduce seating discomfort by proving a cushion that has a substantially continuous and uniform thickness. Such cushions may be made, for example, from Styrofoam or a foam rubber. Such cushions, while softening the seating surface over that of a solid surface, substantially block air flow to the person's posterior, thereby adding to the person's thermal and sweating discomfort.
SUMMARY OF THE INVENTIONThe invention, in one form thereof, is directed to a seat cushion including a flexible body and a plurality of spacing members. The flexible body has a seating surface and a support surface spaced apart from the seating surface. The seating surface has a first area and the support surface has a second area. The plurality of spacing members are spaced apart and distributed across the second area, with each of the plurality of spacing members extending outwardly in a first direction from the support surface.
In a variation of the embodiment described above, the flexible body includes a plurality of ventilation holes.
In still another variation, a fabric cover is installed over the seat cushion.
The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention will be better understood by reference to the following description of an embodiment of the invention taken in conjunction with the accompanying drawings, wherein:
Referring now also to
Flexible body 20 has a seating surface 26 and a support surface 28 spaced apart from seating surface 26. In the present embodiment, the thickness T of flexible body 20 from seating surface 26 to support surface 28 may be, for example, in a range of about 0.4 to 1.0 centimeters. Seating surface 26 has a first area A1 and support surface 28 has a second area A2. In the present embodiment areas A1 and A2 are substantially equal. Also, in the present embodiment, areas A1 and A2 are substantially square, but those skilled in the art will recognize that other shapes may be desirable, such as for example, elongated rectangular, oval, circular, etc., for reasons such as those due to the size or shape of the sitting surface, e.g., sitting surface 14, on which seat cushion 10 is to be placed. In the present embodiment, for example, each of areas A1 and A2 is about 1450 square centimeters, but those skilled in the art will recognize that other area sizes may be desirable, such as due to the size of the user, e.g., large adult, small adult, child, etc.
As best shown in
In the present embodiment, each of the plurality of spacing members 22 respectively extend outwardly from the support surface 28 in the first direction D1 (see
As a general design criteria, as length L1 increases cross-sectional area A3 may increase as well to retain the desired level on non-flexibility, e.g., support. While each of the plurality of spacing members 22 may be substantially non-flexible in direction D2 radially perpendicular to the first direction D1, the non-porous rubber-like compound provides a level of compression along the length L1 to provide a cushioning effect. In addition, the flexible body 20 is flexible and pliable as a combined effect its thickness T, the quantity and size of the plurality of ventilation holes 24, and/or the characteristics of the non-porous rubber-like compound.
As best shown in
Referring also to
A cross-sectional area A4, i.e., the opening size, of each of the plurality of ventilation holes 24 may be, for example, in a range of about three square centimeters to about nine square centimeters. The size and quantity of ventilation holes 24 may be chosen to provide the desired amount of ventilation to the human user 18, while not compromising the structural integrity of flexible body 20. While the present embodiment includes the plurality of ventilation holes 24, it is contemplated that some users may not desire to have the ventilation holes, and thus in some embodiments of the present invention, the inclusion of the plurality of ventilation holes 24 may be optional. Also, for additional ventilation, it is contemplated that additional ventilation holes may be formed through one or more of the plurality of spacing members 22, and through flexible body 20 to seating surface 26.
If desired, fabric cover 12 may include, for example, a logo, a symbol, or a design, 34, formed on or in the fabric of fabric cover 12.
While this invention has been described with respect to an embodiment of the invention, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
