Abstract: A seating arrangement includes a seat portion, a back portion, a support member caused to move between first and second positions, and a back recline lock arrangement that includes an actuator, a lock member caused to move between a locked position when the actuator is in an engaged position where the lock member prevents the support member from moving from the first position toward the second position, and an unlocked position when the actuator is in a disengaged position, and wherein the actuator is configured to move from the disengaged position to the engaged position when the chair back is in the reclined position, and the lock member is prevented from moving from the unlocked position to the locked position until the back assembly is moved from the reclined position to the upright position.

Abstract: A body support structure includes a pair of laterally extending load bearing support segments each having an outer portion coupled to a support structure and an inner portion. Each of the load bearing support segments extends laterally inwardly from the outer portion, and the inner portions are laterally spaced apart so as to define a gap therebetween. A body support member is spaced forwardly from the pair of load bearing support segments. A plurality of links connect the load bearing support segments to the body support member.

Abstract: A backrest includes a primary frame having a pair of laterally spaced first uprights defining a first opening therebetween, a first front surface and a first rear surface. A secondary frame includes a pair of laterally spaced second uprights defining a second opening therebetween, a second rear surface facing the first front surface of the primary frame and a second front surface, wherein the secondary frame is coupled to the primary frame, and wherein at least portions of the first and second openings are aligned. A flexible shell overlies and is coupled to the second front surface of the secondary frame. The flexible shell includes a third rear surface visible through the aligned portions of the first and second openings.

Abstract: A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

Abstract: A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

Abstract: A body support structure includes a shell having a central region, an outer peripheral region spaced from the central region, and at least one array extending between the central region and the outer peripheral region. The at least one array includes a plurality of spaced apart support members and at least one connector connecting adjacent support members within each array. The support members of the at least one array are progressively divided between the central portion and the outer peripheral edge.

Abstract: A seating arrangement includes a base, a lower shell including a first portion coupled to the base and comprising a substantially horizontal portion, a curved transition portion and a backrest portion, a pair of laterally spaced front links extending upwardly from a forward portion of the first portion, a rear link extending upwardly from a rearward portion of the first portion of the lower shell and forwardly of the transition region of the lower shell, and an upper shell comprising a seating portion coupled to the pair of front links and to the rear link, a curved transition portion spaced apart from the curved transition portion of the lower shell and defining an open lateral pass through therebetween, and a backrest portion connected to the backrest portion of the lower shell.

Abstract: A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.

Abstract: A backrest includes a frame having a pair of laterally spaced upright members connected with longitudinally spaced upper and lower members. A flexible shell has opposite sides coupled to the upright members and upper and lower portions coupled to the upper and lower members. The shell includes first and second slots extending longitudinally along opposite sides of the shell inboard of locations where the shell is connected to the upright members, and one or more third slots extending laterally along the lower portion of the shell above a location where the shell is connected to the lower member. Terminal ends of the one or more third slots are spaced apart from lower terminal ends of the first and second slots. In other embodiments, the shell is a three-dimensional molded component having a plurality of openings. In various embodiments, the slots and/or openings provide different levels of compliance to the backrest.

Abstract: A seating arrangement includes a base, a back arrangement and a seat arrangement each supported by the base, the back arrangement movable between an upright position and reclined position, the seat arrangement including a stop member, a shell supported on the base and forming at least a portion of the seat arrangement, the shell including a first portion and second portion movable relative to the first portion, the shell configured such that a downward force exerted on the first portion by a seated user forces the back arrangement from the reclined position toward the upright position, and a tilt limiter coupled to the base and configured to engage the stop member at both the upright position and the reclined position.

Abstract: A body support assembly includes a seat assembly and backrest assembly supported by tilt control assembly. Methods of using and assembling the body support assembly are provided.
