Abstract
Abstract The seat cushion comprises a central slab of cellular material having marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective marginal zone of said central slab and said cellular material of said central slab being of greater resiliency than said cellular material of said side members.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A seat cushion comprising a central slab of cellular material having a person-supporting external surface bonded by marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side members covering a respective said marginal zone of said external surface of said central slab, the juxtaposed faces of said marginal zone and said edge portion having complementary zigzag profiles in a plane perpendicular to said faces and said cellular material of said central slab being of greater resiliency than said cellular material of said side members.
Claim 2
Dependent Claim
101 words
A seat cushion comprising a central slab of cellular material having a person-supporting external surface bonded by marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side members covering a respective said marginal zone of said external surface of said central slab, the juxtaposed faces of said marginal zone and said edge portion having complementary zigzag profiles in a plane perpendicular to said faces and said cellular material of said central slab being of greater resiliency than said cellular material of said side members.
Claim 3
Dependent Claim
104 words
A seat cushion comprising a central slab of cellular material having a person-supporting external surface bounded by marginal zones set back therein, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective said marginal zone of said external surface of said central slab, the juxtaposed faces of said marginal zone and said edge portion having complementary zigzag profiles in a plane perpendicular to said faces and said cellular material of said central slab being of greater resiliency than said cellular material of said side members.
Claim 4
Dependent Claim
104 words
A seat cushion comprising a central slab of cellular material having a person-supporting external surface bounded by marginal zones set back therein, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective said marginal zone of said external surface of said central slab, the juxtaposed faces of said marginal zone and said edge portion having complementary zigzag profiles in a plane perpendicular to said faces and said cellular material of said central slab being of greater resiliency than said cellular material of said side members.
Claim 5
Dependent Claim
25 words
A seat cushion as defined in claim 2 wherein said projecting edge portion of each said side member decreases in thickness towards its free extremity.
Claim 6
Dependent Claim
139 words
A seat cushion comprising a central slab of cellular material having marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective marginal zone of said central slab and said cellular material of said central slab being of greater resiliency than said cellular material of said side members and including a terminal pad of cellular material having a projecting edge portion with a free extremity, said projecting edge portion of said terminal pad covering a marginal zone of said central slab adjacent said marginal portions of said central slab covered by said projecting edge portions of said side members and said cellular material of said terminal pad being of greater resiliency than said cellular material of said central slab.
Claim 7
Dependent Claim
139 words
A seat cushion comprising a central slab of cellular material having marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective marginal zone of said central slab and said cellular material of said central slab being of greater resiliency than said cellular material of said side members and including a terminal pad of cellular material having a projecting edge portion with a free extremity, said projecting edge portion of said terminal pad covering a marginal zone of said central slab adjacent said marginal portions of said central slab covered by said projecting edge portions of said side members and said cellular material of said terminal pad being of greater resiliency than said cellular material of said central slab.
Claim 8
Dependent Claim
22 words
A seat cushion as defined in claim 4 wherein each of said projecting edge portions decreasing in thickness towards its free extremity.
Claim 9
Dependent Claim
99 words
A seat cushion comprising a central slab of cellular material having marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective marginal zone of said central slab, and said cellular material of said central slab being of greater resilIency than said cellular material of said side members wherein said central slab and each said side member abut at an interface, said interface defining in section perpendicular thereto a zigzag line with rounded edges including at least one Z.
Claim 10
Dependent Claim
99 words
A seat cushion comprising a central slab of cellular material having marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective marginal zone of said central slab, and said cellular material of said central slab being of greater resilIency than said cellular material of said side members wherein said central slab and each said side member abut at an interface, said interface defining in section perpendicular thereto a zigzag line with rounded edges including at least one Z.
Claim 11
Dependent Claim
138 words
A seat having a seat portion and a back portion at least one of which portions comprises a frame and a seat cushion supported on said frame, said seat cushion comprising a central slab of cellular material having a person-supporting external surface bounded by marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective marginal zone of said external surface of said central slab, the juxtaposed faces of said marginal zone and said edge portion having complementary zigzag profiles in a plane perpendicular to said faces and said cellular material of said central slab being of greater resiliency than said cellular material of said side members and said frame directly supporting the periphery of said central slab.
Claim 12
Dependent Claim
138 words
A seat having a seat portion and a back portion at least one of which portions comprises a frame and a seat cushion supported on said frame, said seat cushion comprising a central slab of cellular material having a person-supporting external surface bounded by marginal zones, and two side members of cellular material each having a projecting edge portion with a free extremity, the projecting edge portion of each said side member covering a respective marginal zone of said external surface of said central slab, the juxtaposed faces of said marginal zone and said edge portion having complementary zigzag profiles in a plane perpendicular to said faces and said cellular material of said central slab being of greater resiliency than said cellular material of said side members and said frame directly supporting the periphery of said central slab.
