A seating system for wheelchairs and other applications. The seating system includes a base member with an upper surface and a fluid pad positioned on the upper surface. The upper surface is preferably contoured and dimensioned to have areas corresponding to the user's ischial tuberosities and coccyx as well as the user's femurs including trochanters. The fluid pad in the preferred embodiment is one piece and has at least three separate and distinct pouches filled with fluid. Each pouch includes seals to contain the fluid in each pouch and to isolate and prevent fluid communication with the fluid in the other two pouches. Each pouch of the pad is then respectively positioned on the upper surface of the base member under the user's ischial tuberosities and coccyx. In this manner, each of the user's ischial tuberosities and coccyx is thereby supported on its own separate and distinct fluid pouch.
In a seating system having a base member with an upper surface and a pad positioned on said upper surface to receive and support a user's buttocks including the user's ischial tuberosities and coccyx, the improvement wherein said pad includes at least three separate and distinct pouches containing a fluid having a viscosity of at least one and means for positioning a first of said three pouches under one of the user's ischial tuberosities, a second of said three pouches under the other of the user's ischial tuberosities, and a third of said three pouches under the user's coccyx, each pouch including means for sealing the fluid within each pouch to prevent fluid communication with the fluid in the other two pouches wherein each pouch has at least portions thereof respectively positioned immediately adjacent a portion of each of the other two pouches.
A seating system for supporting a user's buttocks including the user's ischial tuberosities and coccyx, said seating system including means for respectively supporting each of the user's ischial tuberosities and coccyx on one of at least three separate and distinct pouches, each pouch containing a fluid having a viscosity of at least one and further having sealing means for containing the fluid within each pouch to isolate and prevent fluid communication with the fluid in the other two pouches, said seating system further including a base member with an upper surface and means for positioning said pouches on said upper surface of said base member, said upper surface of the base member having three areas dimensioned to substantially correspond to the areas of the user's ischial tuberosities and coccyx and said positioning means positions a first of said three pouches substantially over the area of the upper surface corresponding to one of the user's ischial tuberosities, a second of said three pouches substantially over the area of the upper surface corresponding to the other of the user's ischial tuberosities, and a third of said three pouches substantially over the area of the upper surface corresponding to the user's coccyx whereby each of the user's ischial tuberosities and coccyx is respectively supported on one of the three separate and distinct pouches wherein the respective sealing means of said first and third pouches include a common sealing seam, the respective sealing means of said second and third pouches include a common sealing seam, and the respective sealing means of said first and second pouches include a common sealing seam.
The seating system of claim 27 wherein the seating system supports the user's buttocks including each half side of the user's buttocks and said first pouch is dimensioned substantially the same size as one of the half sides of the user's buttocks.
A seating system for supporting a user's buttocks including the user's ischial tuberosities and coccyx, said seating system including means for respectively supporting each of the user's ischial tuberosities and coccyx on one of at least three separate and distinct pouches, each pouch containing a fluid having a viscosity of at least one and further having sealing means for containing the fluid within each pouch to isolate and prevent fluid communication with the fluid in the other two pouches, said seating system further including a base member with an upper surface and means for positioning said pouches on said upper surface of said base member, said upper surface of the base member having three areas dimensioned to substantially correspond to the areas of the user's ischial tuberosities and coccyx and said positioning means positions a first of said three pouches substantially over the area of the upper surface corresponding to one of the user's ischial tuberosities, a second of said three pouches substantially over the area of the upper surface corresponding to the other of the user's ischial tuberosities, and a third of said three pouches substantially over the area of the upper surface corresponding to the user's coccyx whereby each of the user's ischial tuberosities and coccyx is respectively supported on one of the three separate and distinct pouches, said upper surface of said base member extending outwardly on each side of a central plane passing through said upper surface and said positioning means positions said first and second pouches on said upper surface to extent outwardly of said central plane on opposite sides thereof, said seating system further including at least two additional pouches containing fluid and means for positioning one of said additional pouches outwardly of said first pouch relative to said central plane and means for positioning the second of said additional pouches outwardly of said second pouch relative to said central plane.
In a seating system having a base member with an upper surface and a pad positioned on said upper surface to receive and support a user's buttocks including the user's ischial tuberosities and coccyx, the improvement wherein said pad includes at least three separate and distinct pouches containing a fluid having a viscosity of at least one and means for positioning a first of said three pouches under one of the user's ischial tuberosities, a second of said three pouches under the other of the user's ischial tuberosities, and a third of said three pouches under the user's coccyx, each pouch including means for sealing the fluid within each pouch to prevent fluid communication with the fluid in the other two pouches wherein each sealing means includes a sealing seam and said sealing seam for each pouch has at least a common portion with the sealing seam of each of the other two pouches.
