Abstract
A cushioning assembly comprises a foundation, a plurality of springs mounted on the foundation, and a pad resting on the springs. Each spring is formed of plastic and forms a through-chamber having an axis. The axes of the springs lie in a common plane oriented perpendicular to the loading applied thereto when a user rests on the assembly. Pad-supporting plates are removably attached to the spring bodies, e.g., by clamp members.
Claims16
A cushioning assembly, comprising:
- a foundation;
- and
- a plurality of springs mounted on said foundation, said springs arranged in substantially parallel rows, each row including two springs arranged adjacent respective ends of the row and a plurality of springs disposed between said two springs, whereby said springs of all of said rows together define a support area adapted to support a pad, each spring comprising:
- an elastically compressible portion formed of plastic and comprising a hollow body forming at least one through-chamber defining an axis,
- a mounting portion disposed at a bottom of said elastically compressible portion and including structure for connection with said foundation, and
- a pad-supporting plate disposed at a top of said elastically compressible portion and adapted for supporting a pad;
- said axes of said springs lying in a common plane oriented parallel to said pad-supporting plates and perpendicular to a loading applied to the spring assembly by a user,
- wherein said foundation comprises a plurality of parallel slats, said springs being mounted along said slats, said springs mounted on each slat defining one of said rows, said mounting portion forming a slat chamber extending completely through said spring and through which a slat extends.
