Abstract

An office chair including a chair back assembly that is independently adjustable to adjust the vertical height of the chair back and to provide lumbar support. The chair back assembly includes a flexible back shell that is movable vertically along a back support yoke. The vertical movement of the flexible back shell adjusts the vertical height of the chair back assembly relative to the seat. The chair back assembly further includes a lumbar adjustment mechanism having an adjustment cable connected to a bottom end of the flexible back shell. Operation of the lumbar adjustment mechanism moves the bottom end of the flexible back shell vertically within a pair of spaced lower movement slots. The movement of the bottom end of the flexible back shell increases the amount that the flexible back shell protrudes from the back support yoke, thereby increasing the lumbar support.

Abstract

A chair having an integrally molded chair back and seat that move together upon reclining movement of a user. The seat includes a series of glides that travel along a glide track mounted to a fixed support frame. A bias spring, connects the support frame to the seat and chair back to urge the seat and chair back into an upright position. The chair includes a pair of ganging arms that are movable between a storage position and an operative position. In the storage position, the ganging arms are concealed within a bottom cover. When in the extended, operative position, the ganging arms allow multiple chairs to be ganged together.

Abstract

An office chair including a linking mechanism between a movable chair seat and a pivotable chair back. The mounting arrangement between the chair back and the chair seat includes swing arm assembly that is pivotally connected to the chair seat. When the chair seat moves forward, the swing arm assembly moves with the chair seat and causes the chair back to pivot and move relative to a stationary support arm. The stationary support arm includes a curved support face that moves within a movement slot formed on the swing arm assembly. The movement slot includes a roller that helps guide relative movement between the two components. The chair seat includes a thigh support portion that allows the user to adjust the seat depth as desired.
