Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
233 words
An improved seat cushion comprising: a) at least one contoured substrate including i) 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, each of said cell walls having an upper extremity and a lower extremity, at least one of said upper and said lower extremity forming a contoured surface, and ii) means for maintaining said first core in its expanded configuration, said first core being anisotropically flexible and capable of stabilizing and spreading a load exerted thereupon by a user of said cushion; b) at least one planar substrate attached to one of said upper and said lower extremity of said first core, said planar substrate having i) a second 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, each of said cell walls having an upper extremity and a lower extremity, each of said upper and said lower extremity forming a planar surface, and ii) means for maintaining said second core in its expanded configuration, said second core being anisotropically flexible and capable of stabilizing and spreading a load exerted thereupon by said user of said cushion; and c) whereby predetermined prominences of said user's body are received in said contours formed in said contoured surface.
Claim 2
Dependent Claim
233 words
An improved seat cushion comprising: a) at least one contoured substrate including i) 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, each of said cell walls having an upper extremity and a lower extremity, at least one of said upper and said lower extremity forming a contoured surface, and ii) means for maintaining said first core in its expanded configuration, said first core being anisotropically flexible and capable of stabilizing and spreading a load exerted thereupon by a user of said cushion; b) at least one planar substrate attached to one of said upper and said lower extremity of said first core, said planar substrate having i) a second 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, each of said cell walls having an upper extremity and a lower extremity, each of said upper and said lower extremity forming a planar surface, and ii) means for maintaining said second core in its expanded configuration, said second core being anisotropically flexible and capable of stabilizing and spreading a load exerted thereupon by said user of said cushion; and c) whereby predetermined prominences of said user's body are received in said contours formed in said contoured surface.
Claim 3
Dependent Claim
46 words
An improved seat cushion as recited in claim 1, wherein said means for maintaining of each said first and said second honeycomb cores includes: (a) a planarizing thermal compression deformation of a first face of said core formed by said upper extremity of said cell walls.
Claim 4
Dependent Claim
46 words
An improved seat cushion as recited in claim 2, wherein said means for maintaining of each said first and said second honeycomb cores includes: (a) a planarizing thermal compression deformation of a second face of said core formed by said lower extremity of said cell walls.
Claim 5
Dependent Claim
40 words
An improved seat cushion as recited in claim 3, wherein said means for maintaining of each said first and said second honeycomb cores further includes: (a) a first facing sheet of said resilient thermoplastic material bonded to said first face.
Claim 6
Dependent Claim
40 words
An improved seat cushion as recited in claim 4, wherein said means for maintaining of each said first and said second honeycomb cores further includes: (a) a second facing sheet of said resilient thermoplastic material bonded to said second face.
Claim 7
Dependent Claim
27 words
An improved seat cushion as recited in claim 5 wherein said cell walls of at least some of said cells of said first core have perforations therein.
Claim 8
Dependent Claim
27 words
An improved seat cushion as recited in claim 6 wherein said cell walls of at least some of said cells of said second core have perforations therein.
