Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
A cushioning element for seating or sleeping of humans and the like, the cushioning element having a synthetic resinous resilient cellular cushioning body, the cushioning body having ends and edges at least a principal human body-supporting face adapted to be disposed adjacent a human body when the cushioning element is in use, the cushioning body defining on the body-supporting face a plurality of grooves, the grooves having a width of from about one-eighth to about three-eighths of an inch, the plurality of grooves extending into the body and dividing the body-supporting face and a portion of the body adjacent to the body-supporting face into a plurality of adjacent spaced-apart bosses the grooves terminating at a location adjacent the ends and edges thereby providing an edge portion which is more resistant to compression than the area having grooves with the further limitation the bosses are individually deflectable and exhibit individual recovery when a deflecting force is applied and removed respectively, thereby providing a body-supporting face of a plurality of body-supporting face bosses each at least partially deformable independent of adjacent body-supporting face bosses.
Claim 2
Dependent Claim
182 words
A cushioning element for seating or sleeping of humans and the like, the cushioning element having a synthetic resinous resilient cellular cushioning body, the cushioning body having ends and edges at least a principal human body-supporting face adapted to be disposed adjacent a human body when the cushioning element is in use, the cushioning body defining on the body-supporting face a plurality of grooves, the grooves having a width of from about one-eighth to about three-eighths of an inch, the plurality of grooves extending into the body and dividing the body-supporting face and a portion of the body adjacent to the body-supporting face into a plurality of adjacent spaced-apart bosses the grooves terminating at a location adjacent the ends and edges thereby providing an edge portion which is more resistant to compression than the area having grooves with the further limitation the bosses are individually deflectable and exhibit individual recovery when a deflecting force is applied and removed respectively, thereby providing a body-supporting face of a plurality of body-supporting face bosses each at least partially deformable independent of adjacent body-supporting face bosses.
Claim 3
Dependent Claim
14 words
The cushioning element of claim 1 in the form of a generally planar slab.
Claim 4
Dependent Claim
12 words
The cushioning element of claim 2 having the form of a mattress.
Claim 5
Dependent Claim
15 words
The cushioning element of claim 3 having a generally continuous covering over the body-supporting surface.
Claim 6
Dependent Claim
217 words
A mattress for the support of the human body, the mattress comprising a mattresscover generally enclosing a synthetic resinous resilient cellulose cushioning body, the cushioning body having ends and edges, at least a principal human body-supporting face adapted to be disposed adjacent a human body when the cushioning element is in use, the cushioning body defining on the body supporting face a plurality of grooves, the plurality of grooves extending into the body and dividing the body-supporting face and a portion of the body adjacent to the body-supporting face into a plurality of adjacent spaced-apart bosses with the further limitation the bosses are individually deflectable and exhibit individual recovery when a deflecting force applied and romoved is removed respectively, thereby providing a body-supporting face of a plurality of body-supporting face bosses each at least partially deformable independent of adjacent body-supporting face bosses the grooves terminating at a location adjacent the ends and edges thereby providing an edge portion which is more resistant to compression than the area having grooves with the further limitation that the grooves have a width from about one-eighth of an inch to three-eighths of an inch, the grooves are from one-half to two and one-half inches in depth and are spaced on centers of from about two and one-half to about four inches.
Claim 7
Dependent Claim
217 words
A mattress for the support of the human body, the mattress comprising a mattresscover generally enclosing a synthetic resinous resilient cellulose cushioning body, the cushioning body having ends and edges, at least a principal human body-supporting face adapted to be disposed adjacent a human body when the cushioning element is in use, the cushioning body defining on the body supporting face a plurality of grooves, the plurality of grooves extending into the body and dividing the body-supporting face and a portion of the body adjacent to the body-supporting face into a plurality of adjacent spaced-apart bosses with the further limitation the bosses are individually deflectable and exhibit individual recovery when a deflecting force applied and romoved is removed respectively, thereby providing a body-supporting face of a plurality of body-supporting face bosses each at least partially deformable independent of adjacent body-supporting face bosses the grooves terminating at a location adjacent the ends and edges thereby providing an edge portion which is more resistant to compression than the area having grooves with the further limitation that the grooves have a width from about one-eighth of an inch to three-eighths of an inch, the grooves are from one-half to two and one-half inches in depth and are spaced on centers of from about two and one-half to about four inches.
