Provided is a core material of a seat cushion for a vehicle, including: a thermoplastic resin expanded beads molded article having a substantially rectangular shape in top view, that has thick portions on a front side and both sides of a circumferential portion thereof, and that has an occupant seating portion on an upper surface in an inner region thereof; and an annular frame member that is insert-molded at the circumferential portion of the thermoplastic resin expanded beads molded article. In the thermoplastic resin expanded beads molded article, formed are first slits having: slit pieces that extend along a front frame member at a position in front of the occupant sitting part and inside from the front frame part; and slit pieces that extend along a side frame member at a position outside from the occupant sitting part and inside from a side frame part.

The present invention provides a soft polyurethane foam molded atticle which has a mounting surface (1A) can be obtained by foaming and molding a raw foaming liquid, and has a constitution which a ratio of a diameter of a foaming cell in the horizontal direction X along the mounting surface (1A) to a diameter of the foaming cell in the vertical direction Y orthogonal to the mounting surface (1A) increases toward the mounting surface (1A) in the vertical direction (Y).

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

A portable lumbar support and ergonomic chair having a lumbar support. The lumbar support has a seat hingedly coupled to a seat back having a teardrop-shaped lumbar support seat back cushion. A rigid back support portion may be rotated forward about hinges to collapse substantially parallel to the seat frame and backward to open to a variety of angles with respect to the seat frame. The seat back freely pivots around an upper lateral axis, and the rigid back support portion is linearly adjustable to space the seat back toward and away from the hinges to enable raising or lowering the upper lateral axis and thus the seat back with respect to the lower lateral axis. This provides multiple ways of changing which part of the teardrop-shaped lumbar support curve hits your lumbar curve for proper support. Variable lumbar lordotic support is thus provided.

The invention relates to a vacuum insulation panel arrangement on a vacuum insulation panel having two mutually opposite outer faces and edges that connect these outer faces, and having a protective layer that surrounds the vacuum insulation panel tightly on all sides. The invention is characterized in that, in order to form the protective layer, the vacuum insulation panel is coated entirely with flexible synthetic foam.

The present disclosure provides a support device including a body interface layer resting against a user's body, a core adjacent the body interface layer with a plurality of independently acting micro coils surrounded by an enclosure layer, a stabilizing layer more rigid than the enclosure layer and the body interface layer, and an outer layer adjacent the stabilizing layer and which rests against an external surface such as a seat back when the device is in use. The body interface layer includes a curvilinear or parabolic profile with its inflection point toward a central region of the device and tapering toward lateral ends thereof. The body interface layer is thickest toward its intermediate portion which aligns with a central row of the spiral biasing devices, the body interface layer thinner outer intermediate regions aligning with outer spiral biasing device rows, providing for a consistently distributed pressure against the body.

A seating arrangement includes a base, a seat assembly operably coupled to the base, and a back assembly that includes a substantially rigid back frame including a pair of side portions spaced from one another and extending upward from the base, and a substantially flexible back shell including a front surface and a rear surface opposite the front surface, a plurality of laterally-extending slots that extend between the front surface and the rear surface and that cooperate to define a plurality of laterally-extending ribs therebetween, where a pair of laterally-extending ribs of the plurality of laterally-extending ribs are connected to one another via a vertically-extending rib located at a substantial midpoint across a width of the back shell, and wherein the back shell is coupled to each of the side portions of the back frame at locations above the plurality of laterally-extending slots.
