Anatomical support apparatus

An improved seat cushion comprising:

• a first panel including
• a honeycomb core formed of resilient thermoplastic and including cell walls defining a plurality of contiguous regularly shaped cells, at least some of said cell walls of said first panel having perforations therein, the extremities of said cell walls defining first and second core faces;
• means for maintaining said core in its expanded configuration so that it will anisotropically flex to stabilize and spread any load applied thereto by a user of said apparatus, and including a first facing sheet of said resilient material bonded to said first core face and a second facing sheet of said resilient material bonded to said second core face, said first and second facing sheets of said first panel being sealingly jointed together about the perimeter of said core to provide a chamber;
• and
• mean fluid-communicatively coupled to said first panel for selectively adding fluid to or subtracting fluid from said chamber, said fluid flowing through the perforations of said walls to change certain characteristics of said first panel.

An improved mattress pad comprising:

• a first panel including
• a first honeycomb core formed of resilient thermoplastic material and including cell walls defining a plurality of contiguous regularly shaped cells, the opposite extremities of which form first and second core faces on opposite sides of said first core, at least some of said cell walls of said first panel have perforations therein;
• means tending to maintain said first core in its expanded configuration so that it will anisotropically flex to stabilize and spread any load applied thereto by a user, and including a first facing sheet bonded to said first face and a second facing sheet bonded to said second face, said first facing sheet and said second facing sheet of said first panel being sealingly joined together about the perimeter of said core to provide a sealed chamber envelope said first core;
• and
• means fluid-communicatively coupled to said first panel for selectively adding fluid to or subtracting fluid from said sealed chamber, said fluid flowing into said cells and through the perforations of said walls to change certain characteristics of said first panel.

In an anatomical support apparatus having a supporting frame, a perforated outer envelope, and a resilient inner body encased within said envelope, both said inner body and said envelope being supported by said frame, an improved resilient inner body, comprising:

• a first panel including
• a first honeycomb core formed of resilient thermoplastic material and including cell walls defining a plurality of contiguous regularly shaped cells, the opposite extremities of said cell walls forming first and second core faces on opposite sides of said first core;
• and
• means tending to maintain said first core in its expanded cellular configuration so that it will anisotropically flex to stabilize and spread any load applied thereto by a user of said apparatus, and including at least a first facing sheet bonded to said first face and a second facing sheet of material bonded to said second face, said first facing sheet and said second facing sheet of said first panel being perforated and joined together about the perimeter of said core to provide a chamber enveloping said first core;
• and
• means fluid-communicatively coupled to said first panel for adding fluid to said chamber, said fluid flowing through said perforations of said walls and at least one of said first and second facing sheets.

An improved seat cushion comprising:

• a first panel including
• a honeycomb core formed of resilient thermoplastic material and including cell walls defining a plurality of contiguous, regularly shaped cells, at least some of said cell walls panel having perforations therein, the extremities of said cell walls defining first and second core faces;
• means for maintaining said core in its expanded configuration so that it will anisotropically flex to stabilize and spread any load applied thereto by a user, and including a perforated first facing sheet of said resilient thermoplastic material bonded to said first core face and a second facing sheet of said resilient thermoplastic material bonded to said second core face, said first and second facing sheets being sealingly joined together about the perimeter of said core to provide a chamber;
• and
• means fluid-communicatively coupled to said first panel for adding fluid to said chamber, said fluid flowing through said perforations of said walls and said first facing sheet.

An improved mattress pad comprising:

• a first panel including
• a first honeycomb core formed of undulated strips of resilient thermoplastic material, thermal compression bonded together to form cell walls defining a plurality of contiguous regularly shaped cells, the opposite extremities of which form first and second core faces on opposite sides of said first core, at least some of said cells of said first panel have perforations therein;
• means tending to maintain said first core in its expanded configuration so that it will anisotropically flex to stabilize and spread any load applied thereto by a user, and including a first facing sheet bonded to said first face and a second facing sheet bonded to said second face, at least one of said first and second facing sheets being perforated, said first facing sheet and said second facing sheet of said first panel being joined together about the perimeter of said core to provide a chamber enveloping said first core;
• and
• means fluid-communicatively coupled to said first panel for adding fluid to said chamber, said fluid flowing through said perforations of said walls are at least one of said first and second facing sheets.
