Abstract: A method for manufacturing a multi-layered support structure provides ergonomic, adaptable seating support. The method providing multiple cooperative layers to maximize global comfort and support while enhancing adaptation to localized variations in a load, such as in the load applied when a person sits in a chair. The cooperative layers each include elements such as pixels, springs, support rails, and other elements to provide this adaptable comfort and support. The method for manufacturing the multi-layered support structure uses aligned material to provide a flexible yet durable support structure. Accordingly, the method provides a multi-layered support structure, which provides maximum comfort for a wide range of body shapes and sizes.

Abstract: A seating structure includes a central spine and an upper back structure having a pair of arms extending upwardly and outwardly from the central spine. The upper back structure is pivotally connected to the central spine about a first horizontal axis. A back support structure is pivotally connected to the spine about a second horizontal axis and is pivotally connected to the ends of each of the arms about a third horizontal axis.

Abstract: A seat with an adjustable seat depth is also provided, along with various methods for operating the different aspects and embodiments of the seating structure. In one embodiment, a seating structure includes a support structure and a carriage moveably supported by the support structure. The carriage is moveable relative to the support structure in opposite first and second longitudinal directions. A flexible body support member has a first portion coupled to the support structure, a second portion coupled to the carriage, and a third curved portion positioned between the first and second portions. The third portion is moveable toward and away from the support structure as the carriage is moved relative to the support structure in the first and second directions respectively.

Abstract: A suspended pixelated seating structure provides ergonomic, adaptable seating support. The suspended pixelated seating structure includes multiple cooperative layers to maximize global comfort and support while enhancing adaptation to localized variations in a load, such as in the load applied when a person sits in a chair. The cooperative layers each use independent elements such as pixels, springs, support rails, and other elements to provide this adaptable comfort and support. The suspended pixelated seating structure also uses aligned material to provide a flexible yet durable suspended seating structure. Accordingly, the suspended pixelated seating structure provides maximum comfort for a wide range of body shapes and sizes.

Abstract: A connector includes a first component having a socket and a first catch portion and a second component having a post and a resilient arm having a second catch portion. The post is shaped to be received in the socket. The second component is moveable along an axis relative to the first component from a first position wherein the resilient arm is biased such that the second catch portion is in a non-engaged position to a second position wherein the second catch portion is in an engaged position relative to the first catch portion.

Abstract: A seating structure has an articulated seat and back. A rear portion of the seat is automatically pivotable relative to a forward portion of the seat as the seat is tilted between upright and reclined tilt positions. An upper portion of the back is pivotable relative to the lower portion between a neutral position and an extended position, with the upper portion being pivotable relative to the lower portion independent of the tilt position of the back. In one aspect, an adjustment mechanism is coupled between lower and upper back support members and pivots the upper support member between at least first and second support positions. A seat with an adjustable seat depth is also provided, along with various methods for operating the different aspects and embodiments of the seating structure.

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.
