Abstract
A foam material body for a mattress has a core member having two supporting surfaces and provided with a plurality of recesses in each of said surfaces, wherein each of the recesses has an initial recess portion which is open at a respective one of the supporting surfaces, two deeper recess portions extending from the initial portion inwardly from the same and away from one another, and two narrow recess portions each connecting the initial recess portion with a respective one of the deeper recess portions. Each of the recesses has a depth which is smaller than half the thickness of the core member.
Claims21
A foam material body for a mattress, comprising an elongated core member having a length, a width, a thickness and two supporting surfaces spaced from one another in direction of the thickness, said core member having a plurality of recesses provided in each of said supporting surfaces, said recesses being spaced from one another in direction of the length of said core member and each extending in direction of the width of the latter, each of said recesses having an initial recess portion which is open at a respective one of said supporting surfaces and extends from the latter inwardly in direction of the thickness of said core member, two deeper recess portions spaced from said initial portion inwardly substantially in the direction of the thickness of said core member and also spaced away of one another in direction of the length of said core member and together with a respective one of said supporting faces forming a pair of lips which have ends facing toward one another and bounding a free spaced defined by said initial recess portion, and two narrow recess portions each connecting said initial recess portion with a respective one of said deeper recess portions, each of said recesses having a depth, as measured from a respective one of said supporting surfaces in direction of the thickness of said core member, which is smaller than half the thickness of said core member.
An element of furniture, comprising a support;
- and a mattress including an elongated core member which is constituted of foam material and has a length, a width, a thickness and two supporting surfaces spaced from one another in direction of the thickness, said core member having a plurality of recesses provided in each of said supporting surfaces, said recesses being spaced from one another in direction of the length of said core member and each extending in direction of the width of the latter, each of said recesses having an initial recess portion which is open at a respective one of said supporting surfaces and extends from the latter inwardly in direction of the thickness of said core member, two deeper recess portions spaced from said initial portion inwardly substantially in the direction of the thickness of said core member and also spaced away of one another in direction of the length of said core member and together with a respective one of said supporting faces forming a pair of lips which have ends facing toward one another and bounding a free spaced defined by said initial recess portion, and two narrow recess portions each connecting said initial recess portion with a respective one of said deeper recess portions, each of said recesses having a depth, as measured from a respective one of said supporting surfaces in direction of the thickness of said core member, which is smaller than half the thickness of said core member.
A foam material body for a mattress, comprising an elongated core member having a length, a width, a thickness and two supporting surfaces spaced from one another in direction of the thickness, said core member having a plurality of recesses provided in each of said supporting surfaces, said recesses being spaced from one another in direction of the length of said core member and each extending in direction of the width of the latter, said core member having a central plane extending between said supporting surfaces, said recesses being arranged in pairs so that one recess of each pair is provided in one of said supporting surfaces whereas the other recess of the same pair is provided in the other of said supporting surfaces, the recesses of each pair being symmetrical to one another relative to said central plane and parallel to one another, the recesses of each pair having bounding faces facing toward said central plane and curved from a center of each recess inwardly in direction of thickness of said core member and toward said central plane, so that the bounding faces of the recesses of each pair bound therebetween a web.
