Abstract
Abstract A cushion having an outer covering formed of a flexible sheet, with cushioning material therebehind, and with a large number of buttons projecting outwardly from the covering material for contact with a user or his clothing. The buttons are formed of a material having greater thermal conductivity than the flexible covering material, preferably being formed of a ceramic or marble, so that heat is dissipated by conduction from a user through the buttons to air circulation spaces laterally between the buttons.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
165 words
A cushion comprising: a sheet of flexible material; cushioning material at an inner side of said flexible sheet acting to cushion the deformation thereof; and a large number of buttons carried at the outer side of said sheet of material and projecting outwardly therebeyond and having outer surfaces facing in a direction essentially away from said sheet and exposed for supporting contact with a person resting thereagainst or his clothing; adjacent ones of said buttons having side surfaces which are spaced laterally apart in a relation defining air circulation passages between said side surfaces of adjacent buttons and inwardly of said outer surfaces of the buttons; said flexible sheet having portions laterally between adjacent buttons spaced inwardly beyond the level of said outer surfaces and defining inner sides of said air circulation passages; said buttons being formed of rigid nonmetallic, inorganic material having a thermal conductivity greater than that of said flexible sheet to conduct heat from said outer surfaces to said air circulation passages.
Claim 2
Dependent Claim
165 words
A cushion comprising: a sheet of flexible material; cushioning material at an inner side of said flexible sheet acting to cushion the deformation thereof; and a large number of buttons carried at the outer side of said sheet of material and projecting outwardly therebeyond and having outer surfaces facing in a direction essentially away from said sheet and exposed for supporting contact with a person resting thereagainst or his clothing; adjacent ones of said buttons having side surfaces which are spaced laterally apart in a relation defining air circulation passages between said side surfaces of adjacent buttons and inwardly of said outer surfaces of the buttons; said flexible sheet having portions laterally between adjacent buttons spaced inwardly beyond the level of said outer surfaces and defining inner sides of said air circulation passages; said buttons being formed of rigid nonmetallic, inorganic material having a thermal conductivity greater than that of said flexible sheet to conduct heat from said outer surfaces to said air circulation passages.
Claim 3
Dependent Claim
17 words
A cushion as recited in claim 1, in which said buttons are formed of a ceramic material.
Claim 4
Dependent Claim
15 words
A cushion as recited in claim 1, in which said buttons are formed of porcelain.
Claim 5
Dependent Claim
15 words
A cushion as recited in claim 1, in which said buttons are formed of marble.
Claim 6
Dependent Claim
38 words
A cuShion as recited in claim 1, in which said cushion is portable and has a second sheet of flexible material spaced from said first sheet and secured peripherally thereto, with said cushioning material between the two sheets.
Claim 7
Dependent Claim
43 words
A cushion as recited in claim 1, including a retaining element connected to one of said buttons and having a portion received at the inner side of said flexible sheet and bearing outwardly thereagainst to retain the button against detachment from the sheet.
Claim 8
Dependent Claim
65 words
A cushion as recited in claim 1, including a plurality of retaining elements for securing said buttons to said flexible sheet and each having a shank projecting through an opening in said sheet and connected into a recess in a corresponding button, said retaining elements having enlarged heads at the inner side of said flexible sheet bearing outwardly thereagainst to prevent detachment from the sheet.
Claim 9
Dependent Claim
95 words
A cushion as recited in claim 1, including a plurality of retaining elements formed of deformable resinous plastic material for securing said buttons to said flexible sheet, each of said retaining elements having a shank projecting through an opening in said sheet and tightly frictionally received and retained within a recess in a corresponding one of the buttons, each retaining element having an enlarged head at the inner side of said flexible sheet, with a portion of the sheet about a corresponding one of said openings being confined between said head and a corresponding button.
Claim 10
Dependent Claim
36 words
A cushion as recited in claim 8, in which said recesses in the buttons and said shanks of said retaining elements taper progressively to reduced dimensions as they advance in a direction away from said sheet.
Claim 11
Dependent Claim
15 words
A cushion as recited in claim 9, in which said buttons are formed of porcelain.
Claim 12
Dependent Claim
15 words
A cushion as recited in claim 9, in which said buttons are formed of marble.
Claim 13
Dependent Claim
156 words
A cushion as recited in claim 1, including a second sheet of flexible material spaced from said first sheet and attached peripherally thereto, with said cushioning material received between the two sheets; said buttons being formed of porcelain; said outer surfaces of said buttons being convexly rounded; said side surfaces of said buttons tapering gradually toward said outer surfaces; said cushion including a plurality of retaining elements formed of deformable resinous plastic material for securing said buttons respectively to said first mentioned flexible sheet; said retaining elements having tapering shanks projecting through openings in said first mentioned flexible sheet and tightly frictionally retained within tapering recesses formed in the inner sides of said buttons; said retaining elements having enlarged heads received at the inner side of said first sheet, with portions of said first sheet about said openings being confined between said heads and said buttons to prevent detachment of the buttons from said first sheet.
Claim 14
Dependent Claim
50 words
A cushion as recited in claim 1, in which the combined area of said buttons at the level of their widest portions, and in a plane parallel to said flexible sheet, is greater than the combined area of all of said air circulation spaces between the buttons at said level.
