## Title
Seat pad

## Abstract

An improved seat pad and integrated gripping member is provided, which prevents the pad from slipping when placed between a seating surface and individual. The gripping member is permanently attached to the seat pad along its edge and covers a portion of either side of the seating surface. The gripping member is reversible therefore either side of the seat pad may be selectively exposed during use. This allows both seat pad sides to be constructed of different materials, colors, or patterns and be interchangeable when desired by the user.

## Background
CROSS REFERENCED AND RELATED ACTIONS
This application claims the benefits of U.S. patent application Ser. No. 11/265,007 filed Nov. 5, 2007, now filed as a continuation on Mar. 11, 2009.
FIELD OF THE INVENTION
The invention pertains to seat pads, and more particularly to seat pad assemblies that are constructed of a cushion, a non slip member and providing a multi functional, decorative, protective cover assembly for an individual to sit comfortably and securely on an adjoining surface or structure.
BACKGROUND OF THE INVENTION
Many pads exist in the market today that have various shapes, sizes and fashion designs. Seat pads are sold in the market constructed mostly of a fabric like material, and it is not uncommon to find these materials made of synthetic, natural fibers or other man made materials. Filler materials such as foam or other like materials are used to create cushioning comfort in the pad. Pads are typically constructed to provide the same cushioning comfort when the pad is rotated from one side to the other. Chair pads, seat pads, decorative pillows and cushions (hereafter “pads”) are examples of articles that may be placed over a smooth surface and are intended to remain in a stationary position during use. Pads are manufactured for use in boating, vehicles and as home furnishings. These items are typically fastened to chairs, boats and the interior of vehicles using various with the gripping component or surface between the smooth surface (e.g. chair seat) and the bottom facing pad surface. The gripping component or surfaces may be provided as separate items or fixedly attached to one side of the pad or cushion. Gripping surfaces can be provided as separate components that are glued or stuck to the pad or seating surface. These types of non-attached gripping surfaces could become a safety hazard due to the likelihood of separation from the pad. Other pads on the market today provide a removable cover with a one sided fabric layer, a foam insert, and a rubber mesh layer fixed by a bias on the opposite side of the fabric, functional only on one side to prevent slipping. Products can be found in the automotive or consumer products market, where a rubberized material is used to stop slippage of a small child's car seat, or booster. These designs folded with a fabric backing may be reversible but not stable without additional fasteners or fixtures to prevent shifting or rotating movement when weight is applied. Some pads provide one sided gripping surfaces and others provide two sided decorative patterns. It has been noted that there are seat covers in the market, more specifically in the automotive market, that have a seat back, fabric like decorative design and second component, a lower seating portion of rubberized material. The seat cover can be folded at a mid plane to provide a means to overlay the fabric portion, but the overlay of two layers do not provide a means to resist slippage between the two layers, and are often big and bulky to store and to handle. Some pads found constructed of polyvinyl chloride material may offer some slip resistance, but not always adequate in gripping mating surfaces, limiting in material selection. The U.S. Pat. Nos. 6,212,717 and 5,896,603 disclose chair cushions and place mats formed of a top fabric panel attached to a bottom panel that has a high coefficient of friction. The bottom panel is preferably a rubberized web material with an open or mesh pattern. The rubberized material prevents the chair cushion or place mat from sliding over smooth surfaces. U.S. Pat. No. 4,457,032 discloses a cushion having a lower layer that also has a high coefficient of friction. U.S. Pat. No. 5,429,852 shows another chair pad or cushion also having a lower panel with a high coefficient of friction. The U.S. Design Pat. No. 360,794 illustrates a combined child cushion and rubber grip pad unit. A disadvantage of the above chair cushions with permanently attached gripping surfaces is that only one side of the cushion can be exposed during use. If the exposed side becomes irreparably damaged or stained, then it may require replacement because the cushion cannot be reversed. Published patent application No. 20050146177, dated 7 Jul. 2005, to Peter Jerome, discloses a seat cushion with an integral gripping member that prevents the cushion from sliding during use. The gripping member attaches to the cushion by a connecting strap which allows the gripping member to be selectively placed in contact with either panel of the cushion. The gripping member is detachable and is not formed as a reversible permanently attached part of the cushion. If the gripping member was permanently attached the chair pad would be somewhat bulky and cumbersome to handle, and it also should be noted the seat pad and gripping member may not provide sufficient gripping support if twisting or torque is applied to the seating surface, having only one side or panel attached to the gripping member. A disadvantage of the above seat cushion is the seat pad and gripping surface are not fixedly attached to prevent movement between the pad and seating surface and is not an economical means to fabricate the seat pad.
SUMMARY OF THE INVENTION
In accordance with the present invention, an integrated seat pad assembly is provided. The assembly includes an affixed gripping member that forms a pocket and that prevents the pad from sliding during use. The gripping member is secured along its edge to the seat pad forming a pocket thereon. The gripping member is rotatably reversible to be placed in contact with either side of the seat pad contact surface allowing for alternative sides of the seat pad to be selectively chosen, thereby exposing alternative sides for cleanliness, different materials or fashion designs.
The seat pad construction ensures that movement is substantially eliminated between the gripping member and seating surface when the seat pad is applied to the seating surface. The pad offers an improved, secure, means providing a non slip seating surface without the use of strings, ties or other fastening means. The construction of the multi-use pad is manufactured at a low cost minimizing the expense of materials, separate fasteners and/or attaching mechanisms.
The pad gripping component is resiliently reversible, and fixedly attached to at least a portion of the outer perimeter of the pad assembly and preferably at least two sides or points within the midsection of the gusseted edge of the seat pad assembly. The pad gripping component may also be fixedly attached to at least a portion of three sides of the approximate midsection of the gusseted edge in a square or rectangular shape body. The gripping component securely fastened to a portion of the outer perimeter of the seat pad forms a pocket at the upper or lower panel of the seat pad assembly offering an added feature of a convenient storage. For cost savings in manufacturing, the seat pad uses only a portion of the gripping component anti-slip material as compared to the prior art. The pad gripping component can be selectively placed to secure the seat pad from movement, at minimum approximately one quarter to one half of the surface pad area that contacts the seating surface or structure.
In another embodiment of the invention the pad can be made of fabric, plastics or like materials. The pad may include foam, natural fibers, or other like filler materials. The pad may contain a foam or like filler material with a series of holes for air cushioning thereby reducing the amount of foam material used. In some cases the reduction of filler material may be up to more than fifty percent. A thin sheet of resilient film like material can be adhered or laminated to at least one side of the perforated foam or like filler material, providing a different cushion comfort when the chair pad is rotated one side to the other, providing a firm to soft feel. Yet another embodiment of the invention, a seat pad assembly includes an inflatable bladder assembly to vary the height of the seat pad to accommodate different users. The inflatable bladder may consist of a semi-rigid sheet of plastic material, a spring like member and airtight sealed bladder or bag with a valve to allow air into the bladder, providing various heights with desired volume of air entering the bladder, or various adjustments in comfort level as desired by the consumer. The spring member may also assist in improving the rate of filling the bladder with air, where the valve is open to accommodate variations in desired height.
It is therefore an object of the present invention to provide a seat pad with an integrated anti-slip material permanently affixed thereto, the anti-slip material covering a portion of a side of the pad, the seat pad adaptable in shape and size to accommodate various dimensioned seating surfaces.
It is a further object to provide a seat pad that is portable, economical to manufacture, the seat pad having an anti-slip material that is reversible to either side of the pad, the reversible anti-slip material allowing exposure of either side of the seat pad with a functional gripping feature.
It is still a further object of the present invention to provide a seat pad with a convenient storage pouch, the storage pouch formed from the reversible anti-slip material construction.
It is a further object of the present invention to provide a seat pad having different cushioning comfort levels, the levels of cushioning selectable by rotating the seat pad into a different position.
It is still a further object of the present invention to provide a seat pad having an anti-slip material that is coupled with a cache of stacked disposable liners to maintain cleanliness of the seat pad surface; they may include decorative designs or like materials.
It is a further object of the present invention to provide a portable seat pad having an anti-slip material that can be rotatably reversible to either the front or bottom surface of the pad and also provide a thermally insulated component within the pad to retain heat loss between the body and seating surface.
The present invention is not however limited hereto. Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the inventions and the embodiments thereof, from the claims and from the accompanying drawings in which the details of the invention are disclosed as part of this specification.

DETAILED DESCRIPTION
While the invention described is susceptible of embodiment in many different forms, they are shown in the drawing, specification and herein described in the detailed specific embodiments and is not intended to be limited to the specific embodiments illustrated. Referring to FIG. 1 the seat pad 1 of the present invention is constructed of a first upper panel 10, and a second lower panel 15 comprising a semi-rigid or resilient fabric like material. The first upper panel 10, and second lower panel 15 may provide different materials, colors, textures or a design that may be provided by other conventional methods. A third side panel component 20 is provided between the first upper panel 10, and second lower panel 15 to be attached at least a portion of the outer perimeter of upper panel 10, and lower panel 15. The third side panel 20 may be fixedly attached to the upper panel 10, and lower panel 15, to at least a portion of the outer periphery to form a three dimensional shape. An optional alternative fourth side panel component 25, may be fixedly attached to the third side panel 20, and separatively divided about the midsection and having the top outer edge fixedly attached to the edge of the first upper panel 10, and the lower opposing edge attached to the edge of the second lower panel 15, and to receive a third anti-slip gripping component 30 fixedly attached around the midsection of the third or fourth said side panel component 20, and 25 of the said seat pad assembly. A filler opening 35 located between the upper panel 10, and lower panel 15, to load and unload the seat pad 1, with filler material. The filler opening 35 may be secured by a mechanical fastening means for loading and unloading the filler material or otherwise permanently fastened. The seat pad 1 can be constructed in various shapes and sizes to accommodate a stool, chair, or bench type seat. The seat pad 1, material can be made from fabric like materials such as woven, non-woven, flax, wool, cotton, polycotton, vinyl, polyvinyl chloride, nylon olefins, rubber and other synthetic and non-synthetic materials or combination thereof. The seat pad 1, and anti-slip component 30 securely fastened between the upper panel 10, and lower panel 15 with the ability to pivotably rotate about the midsection and upper panel 10, and opposing lower panel 15 with a secure rotatable, reversible means. However it is understood that panels may be combined or may vary in size, shape and length to accommodate various designs and manufacturing methods without deviating from the scope of the invention.
Referring to FIG. 2, the seat pad 1, shown in perspective exploded view, in one embodiment having an upper panel 10, and a lower panel 15 fixedly connected by a third side panel component 20, and an optional fourth side panel component 25, split somewhere about the midsection 26 to attach an anti-slip gripping component 30 having the ability to be reversible and rotatable about the width of the seat pad 1. The fourth side panel 25 may be eliminated to reduce cost in the assembly by using the third side panel 20 to securely attach the upper panel 10, and lower panel 15 having the anti-slip gripping component 30 fixedly attached somewhere about the midsection of the width of the said third side panel 20. A filler material 40, made of synthetic or non synthetic materials not limited to but including, recycled paper, polyurethane foam, polyester fiber, tempurpedic foam (heat sensitive foam) or a combination of polyurethane and tempurpedic foam (heat sensitive foam).
The seat pad 1, assembly can be constructed by stitching, mechanical fastening, radio frequency or heat welding. The seat pad 1, upper panel 10, and lower panel 15, may comprise of a non woven backing material, reflective foil material, to add functional material properties and benefits to the seat cushion, reducing the effect of radiant heat, enabling the user to stay cool, or retain heat inside their body when sitting on the pad in adverse temperature conditions. Aluminum reflective foil reflects radiant heat and therefore minimizes the temperature effects on the pad. In addition to stabilizing internal temperatures of the seat pad, the reflective foil radiates heat back to the human body to minimize heat loss when in use. Other common materials can be used to fill the volumetric three-dimensional structure. Alternative phase change materials may be utilized as a filler material to stabilize the temperature of the seat pad and minimize adverse effects of various temperature conditions.
Referring to FIG. 3a, another variation of a cushioned filler material 41 is shown with a series of thru-holes 42 passing through the body of the cushioned filler material 41 that provide a means to reduce the filler material's volume of material and provide a desired firmness when a thin airtight member 43 made of film or fabric like material and affixed by adhesive 44 to trap air in the holes 42 of the cushion filler material 41 providing an enhanced cushion effect. When the seat pad assembly 1 of FIG. 1 is rotated, the opposite effect is present, where the filler material 41 offers a less dense comfortable seat pad allowing the air to evacuate from the seat pad. When utilizing the filler material 41, the seat pad 1 may be selectively rotated 180° degrees so that the holes 42 are in close proximity to an individual seated. By selectively rotating the seat pad, the user can change the firmness or cushioning effect of the seat pad cushion. A visual indicator or graphics may be applied to the seat pad to indicate firmness, or other effects when rotated to the desired position.
