Patent number: 6701557Abstract: A selectively contoured single unibody foam piece for use as a layer in a cushioned load bearing structure has a first zone with a first surface topography having distinct support properties from a second zone with a second surface topography. The zones of differing topography are formed in the surface of a single, unibody piece of foam by applicable foam cutting techniques. Patterned removal of foam material from a single piece creates zones with different density, ILD or other load bearing properties with different support and feel characteristics. A single unibody component in a responsive flexible support structure has distinct zones with distinct support characteristics, the zones corresponding in location with the anticipated loads and loading patterns of a flexible support device in use.Type: GrantFiled: November 29, 2001Date of Patent: March 9, 2004Assignee: Sealy Technology LLCInventor: Bruce G.

Patent number: 6406009Abstract: Composite material spring modules have a fiber reinforced composite material spring body with attachment fittings integrally formed about the spring body. The attachment fittings are molded of a flexible material which dynamically responds to changes in the shape of the spring body upon deflection. Integral formation of the fittings with the spring body provides a unified single piece module which is readily attachable to any structure where spring support is desired. In one embodiment, a mounting foot is configured for mounting of the spring module directly to a planar surface of a supporting frame member by a fastener, or alternatively configured to engage with a frame member without use of a fastener. The composite material spring modules exhibit the properties of stiffness and return to uncompressed state from total depth deflection without set.Type: GrantFiled: July 12, 2000Date of Patent: June 18, 2002Assignee: Sealy Technology LLCInventors: Eugen Constantinescu, Bruce G.

Patent number: 6023803Abstract: A mattress employs a high density, high ILD convoluted polyurethane foam topper as a major transition layer over the supporting surfaces of an innerspring assembly in order to provide a smooth transition from the support characteristics of the padding and upholstery layers to the innerspring assembly. A high density, high ILD foam material of substantial thickness is positioned between a padding or insulating layer over the innerspring assembly and overlying upholstery, with convolutions in the high density transition layer oriented to extend away from the innerspring assembly. The high density transition layer dominates or masks the support characteristics of the innerspring assembly so that the perception of stiffness or board-like feel of an innerspring is greatly reduced upon initial loading of the mattress.Type: GrantFiled: November 7, 1997Date of Patent: February 15, 2000Assignee: Ohio Mattress Company Licensing and Components GroupInventor: Bruce G.
