A load support structure for a chair includes a tensile material on which a load support surface configured to receive a load of a seated person is formed, a pair of support sections (51) to which the tensile material is attached, and which is elastically deformable in response to a force acting from the tensile material, a first reinforcing section (41) which is disposed to be spaced apart from the pair of support sections (51) in a surface perpendicular direction perpendicular to the load support surface, is located on a side opposite to the load support surface, and extends along an extending direction of the support section, and a connecting body which connects each of both end portion sides of the support section (51) with a corresponding end portion side of both end portion sides of the first reinforcing section (41), in which the support sections (51) are disposed outside the first reinforcing section (41) in a view of the surface perpendicular direction from the load support surface side.

A seat support structure including an elastomeric panel. The elastomeric panel positions and supports a seated occupant. The panel is constrained on a forward side and a rearward side.

A support device has a main support surface for a person's body, including an auxiliary device influencing the main support surface shape. The auxiliary device includes: a group of supports supporting the main support surface, positioned on the side of the main support surface facing away from the body-supporting side, the supports each including a sub-support surface; an adjuster for each sub-support surface influencing the height of each sub-support surface. The device also includes a monitor for each sub-support surface monitoring the height of the respective sub-support surface; and a programmable control unit controlling the adjuster. The supports include an elastically bendable plate connected to the adjuster. The bending plate is connected to the sub-support surface to influence its height depending on the extent of bending imposed by the adjuster. The adjuster includes an electromotor on the concave side of the bending plate.

A method for manufacturing a backrest and/or having a textile covering or the same, and mounted on a chair tubular chassis or the same includes the following steps: folding the lateral edges of the textile covering and seaming the edges to form lateral sheaths by a lateral seam line, affixing at least three visual markers, (notches), to at least one of the ends of each of the lateral sheaths, a first central notch at the lateral edge of each of the sheaths and two peripheral notches on both sides of the respective central notch, folding the free ends of the sheaths by fitting each central notch between the respective peripheral notches, such that the notches extend facing each other, seaming the free ends of the sheaths at the folding area of the notches by a transverse seam line, and turning over the textile covering by bringing out the corners.

A seat or back for a chair comprises a frame having a first edge strut and a second edge strut, the first and second edge struts being on opposite edges of the seat or back. The first edge strut has a groove along all or most of its length, an elongate insert, and a mesh, the mesh being attached to the insert along an edge of the mesh. The insert has a section shaped to correspond to the section of the groove, such that the insert can be urged into the groove, the compression of the groove holding the insert in place.

The present invention relates to interlocking blocks suitable for use at the corners of skeletal frameworks in general and especially at the corners of skeletal frameworks to which rattan mats or other flexible meshes or materials may be attached. Interlocking blocks are disclosed that provide strong and stable corners in skeletal frameworks. Advantageously, rattan or other material may be easily affixed to the interlocking corner blocks while the rattan or other material is slack due to the capability of the interlocking corner blocks to be temporarily disengaged from one another. Tension may then be applied to the attached rattan or other material as the corner blocks are brought into a state of stable and interlocking engagement.

A webbing seat and seat body include a hem and seat section. A seat body is fixed to armrest through hem. A sitting section includes cushion and backrest and material of cushion is same as that of hem. A backrest is composed of webbing with one end sewn to hem and the other to cushion's edge. A front edge of cushion is sewn to hem and back edge suspended through webbing to take shape of stretching backrest.

A body support structure including a backrest, a seat connected to the backrest, and a suspension material connected to the backrest or the seat. The suspension material includes elastomeric filaments with monofilaments and multifilaments. The suspension material further includes a first zone with a first stiffness, a second zone with a second stiffness greater than the first stiffness, and a transition zone positioned between the first zone and the second zone.

A sling chair may include a frame having one or more side rails, each side rail having a J-channel, and a fabric having one or more edges. The J-channel may include a neck and a foot, and be configured to receive a rod connected to a fabric edge. A locking strip may be inserted and force fit into the J-channel to lock the fabric edge and rod in the J-channel. The locking strip may include one or more lateral protrusions for mating with a ridge along an inner surface of the side rail.
