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 frame includes laterally spaced apart first and second support locations. A leaf spring has a longitudinal axis and extends between the first and second support locations. The leaf spring includes opposite first and second ends coupled to the frame along the longitudinal axis. A flexible shell is coupled to the frame at a third support location longitudinally spaced apart from the first and second support locations. The flexible shell is coupled to the leaf spring between the first and second support locations.

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.

Abstract: A seating arrangement includes a back arrangement movable between upright and reclined positions, a linkage arrangement including a first link member comprising a portion of a seat arrangement, a second link member supported on a base, flexibly resilient front link members extending between forward portions of the first and second link members and being integral with the second link member, and a rigid rear link member extending between rearward portions of the first and second link members including a separate piece from the first or second link members, wherein the rearward portion of the first link member extends laterally in a first plane when the back arrangement is upright, and laterally in a second plane when the back arrangement is reclined, where the second plane is angled with respect to the first plane, and is positioned farther away from the base when the back arrangement is reclined than when upright.

Abstract: A body support assembly includes a moveable body support member coupled to a deflectable suspension material. Methods of using and assembling the body support assembly are provided.

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 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 seating unit for use in a space including a supporting floor surface, the seating unit comprising a seat structure comprising a mounting bracket having a female connector, a tablet assembly comprising a support arm having a mounting collar on an end and a base having a lower end to be supported by the floor surface and including a base mounting assembly and wherein the base mounting assembly comprises a cup attached to the base, a base tube having a first end inserted into the cup and a second end extending through the mounting collar and mateably engaging the female connector.

Abstract: A body support structure includes a base, a seat and a backrest, with the backrest connected to the base with a torsion leaf spring. The torsion leaf spring may be configured with a plurality of fingers, and/or one or more flex regions. One or more struts may be connected between the seat or backrest and the base. In another aspect, the seat and/or backrest may be supported with one or more links that provide a counter-intuitive motion. In another aspect, a link may be coupled to a support with a flexible blade.

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.
