| 126 | OFFICE, WORK AND LEISURE CHAIR AND RETROFIT KIT FOR A CHAIR OR A SEAT SURFACE FOR CAUSING SUBLIMINAL MOVEMENTS OF THE PERSON SITTING THEREON | US15499063 | 2017-04-27 | US20170290432A1 | 2017-10-12 | Andreas Reinhard |
| An office, work and leisure chair and retrofit kit for subliminal motions of the seated person. The chair has a cruciform base (1) with rollers (4), a pneumatic spring-action post (2) with an interface plate (5) for a seat panel (21) and seat pad (19), and a backrest (22). The seat panel is mounted with wobble capability on a pneumatic cushion, which has deformable air chambers (18, 35) connected by connecting hoses (27) and lies on an elastically deformable hollow body (14). The hollow body pumps the air chambers when a person sits down and stands up. A pump hose (12) with a one-way valve leads from the hollow body to compensate for leakage losses. Connecting hoses between the air chambers have valves (31; 75; 89) such that the wobbling distance of the seat panel and the damping of the wobbling motion is variable. | ||||||

| A seat having particular application for a chair to enhance the comfort of one seated in the chair. A plurality of (e.g., foam) cushion layers laying one over the other are located at the top of the seat. One of the plurality of foam cushion layers is manufactured from a material having a memory which conforms to and temporarily retains the shape of the user. Located at the bottom of the seat below the plurality of cushion layers are a plurality of coil springs that stand upwardly against the cushion layers in side-by-side alignment with one another so that the back of the seat is firmer than the front. The plurality of cushion layers are arranged in a stack such that the density of the memory foam cushion layer is greater than the density of the other ones of the plurality of cushion layers. | ||||||

| 131 | Collapsible Bolster Cushion | US13048157 | 2011-03-15 | US20120235458A1 | 2012-09-20 | Christer Andersson; Odd Jaegtnes |
| A collapsible bolster cushion for a collapsible seat is provided. The collapsible bolster cushion includes a first support member that is attachable to a seat bottom or a seat back and a second support member. A separator element is disposed between the first and second support members. The separator element is movable between a first orientation and a second orientation such that in the first orientation, the separator element resiliently biases a portion of the second support member away from the first support member, and when the separator element is in the second orientation, the portion of the second support member is permitted to collapse toward the first support member to allow the seat to collapse to the folded position. An actuator moves the separator element between the first and second orientations. | ||||||
| 132 | DROP-IN GRID BASE FOR COIL UNITS | US13005129 | 2011-01-12 | US20120175829A1 | 2012-07-12 | LARRY I. BULLARD |
| A drop-in grid base for coil units is provided. A plurality of extruded plastic tubes, plastic-covered wire profiles, and cross wires are arranged in substantially the same plane to form a grid foundation. The cross wires intersect the extruded plastic tubes and wire profiles. Base wires having a series of shallow, v-shaped notches are interwoven in substantially the same plane as the grid foundation. The ends of the base wires are looped for attachment inside the seating cavity of a framed furniture product. A coil unit may be attached directly to the drop-in grid base. Alternatively, the drop-in grid base may be separately installed into a seating cavity frame, for later installation of a coil unit on top of the drop-in grid base. | ||||||
| 133 | Seating suspension assembly formation method | US916512 | 1997-08-22 | US5894664A | 1999-04-20 | Larry I. Bullard; Allen Sigmon; Roger Tornero |
| A seating suspension assembly provides efficiency in the manufacture of upholstered furniture such as chairs, sofas or the like. The preferred form of the invention comprises a pair of flexible, durable fabric straps having coil springs fixedly positioned therebetween. The fabric can be attached to a rigid wooden chair seat frame and the suspension assembly stapled or tacked thereto. The coil springs are thus suspended between the front and back of the frame. Upon upholstering, the suspension assembly provides a comfortable, crowned seat for the user. A method of forming the seating suspension assembly is also disclosed. | ||||||
| 134 | Spring insulator for wire spring cushioning structures such as mattresses | US37278573 | 1973-06-22 | US3923293A | 1975-12-02 | WIEGAND DONALD E |
| A spring insulator in the form of a specified flexible polyethylene plastic foam sheet is provided for wire spring cushion structures such as are employed in mattresses for preventing the soft cushioning material from dimpling down into the springs and for preventing the objectionable feel of the wire springs from penetrating through the cushioning material. The flexible polyethylene foam sheet spring insulator may be used alone or in combination with other materials such as plastic netting. The polyethylene foam sheet may be provided with means for dampening the sound which may be generated by contact between insulators and wire spring cushioning.

| 136 | Plastic spring | US23662172 | 1972-03-21 | US3815887A | 1974-06-11 | CURTIS W; TRIMBLE D |
| A thin wall hollow, corrugated plastic spring is provided which has a plurality of annular peaks, each separated by a respective one of a plurality of annular valleys. A first group of bottoms of respective valleys are spaced a first distance from the longitudinal axis of the spring and a second group of valley bottoms, each of which alternate with a bottom of the first group, are spaced a second distance from the longitudinal axis of the spring. The peaks are arranged in the manner as the valley bottoms thereby providing a telescopic effect of the valley bottoms and a telescopic effect of the peaks when the spring is fully compressed. As modifications, all of the peaks may be at the same distance from the longitudinal axis while the distances of the valley bottoms vary as above described or vice versa. This provides for a telescoping effect of either the peaks or the valley bottoms. The spring rate is non-linear. The spring is preferably made of polypropylene and has primary utility in seating and reclining applications such as chairs, sofas, and bedding.
