Abstract: A body support structure includes a molded polymeric support grid having a three-dimensional molded contour. The support grid includes a body support region having a plurality of through openings separated by a plurality of lands. In one embodiment, an area of the openings is greater than an area of the lands. In another embodiment, the ratio of a surface area of the lands relative to an area defined by an outer peripheral edge is less than or equal to 0.74. A fabric layer is bonded to the plurality of lands and covers the plurality of openings. Methods of manufacturing and recycling the body structure are also provided.

Abstract: A tiltable chair including a base, a fulcrum member having a curved support surface, a back support pivotally connected to the base at a pivot axis and pivotable between at least an upright position and a rearward tilt position, and at least one leaf spring having first and second ends, with the first end being restrained by the base. The at least one leaf spring engages the curved support surface of the fulcrum member at a first contact point when the back support is in the upright position and at a second contact point when the back support is in the rearward tilt position, wherein the second contact point is positioned rearwardly on the at least one leaf spring relative to the first contact point. A link member is pivotally connected to the back support at a first pivot location and is pivotally connected to the at least one leaf spring at a second pivot location. The link member defines a vector between the first and second pivot locations and the first pivot location and the pivot axis define a plane. The vector and the plane define a first angle when the back support is in the upright position and a second angle when the back support is in the rearward tilt position, wherein the second angle is closer to ninety degrees than the first angle. A method of using a chair is also provided.

Abstract: A chair includes a base, a support element and a torsion element. The support element is coupled to the base and includes a seat region, a backrest region and a transition region connecting the seat region and the backrest region. The backrest region is reclinable relative to the seat region by way of elastic deformation of the support element. The torsion element is coupled to the base and to the backrest region. The torsion element controls the reclining of the backrest region relative to the seat region. The support element is exclusively connected to the torsion element above a lumbar region, wherein the backrest region can be inclined and/or twisted in relation to the seat region.

Abstract: A tilt assembly comprising a tilt housing, a body support member pivotally attached to said tilt housing about a first horizontal axis and a spring mounted to said tilt housing at a second horizontal axis. The body support member is moveable between a first and second position. The second horizontal axis is adjustably moveable relative to the first horizontal axis. The spring biases said body support member at a first location when the body support member is in the first position and at a second location when the body support member is in the second position, with the second location being a greater distance from the first horizontal axis than the first location. A method for supporting a chair body support member is also provided. The method comprises moving the second horizontal axis to a desired position relative to the first horizontal axis, reclining the body support member, and biasing the body support member at first and second locations when the body support member is in the first and second positions respectively.
