Abstract: A chair, which has a cylinder for controlling the configuration of a chair or the seat height of a chair, is operated by a flexible cable. The flexible cable is attached to an adjustment member that is not fixedly attached to the cylinder, thereby permitting the cylinder to be replaced without replacing the adjustment member.

Abstract: A seating unit comprises a support member; a seat member pivotally mounted on the support member; an arm rest member having an actuating button positioned in the arm rest member, the button being movable between a first position and a second position; a fluid pressure cylinder having actuating means and operatively connected to the seat member for adjustment of the inclination thereof; and, a flexible cable having a first end connected to the button and a second end operatively connected to the actuating member. When the button is moved from the first position to the second position, the actuation member is actuated so that the inclination of the back member or the seat member may be adjusted and when the button is moved from the second position to the first position, the inclination of the back member or the seat member is fixed.

Abstract: A chair comprises a seat and a back rest. At least one vibrator is positioned in the seat and/or the back rest. The chair further comprises a housing for receiving a replaceable battery for powering the vibrator. A main power control is positioned so as to be accessible to a person when seated in the chair. A separate mobile controller, which includes controls for actuating the vibrator, is provided.

Abstract: A seating unit comprises support member, a seat member; a back rest member pivotally mounted with respect to the seat member; an arm rest member having an actuating button positioned in the arm rest member, the button being movable between a first position and a second position; a cylinder containing a non-compressible fluid having actuating and operatively connected to the back rest member for adjustment of the inclination thereof; and, a flexible cable having a first end connected to the button and a second end mechanically connected to the actuating member.

Abstract: A lumbar support includes a pocket within the chair back and a lumbar cushion, of a particular cross-sectional shape is completely disposed within that pocket and sited approximately complementary to a person's lumbar region. The lumbar cushion includes a unitary, open-cell, elastically-resilient cushion of foam, the cushion of foam being fixed within a flexible, air-impermeable envelope. The foam has an air inlet/outlet conduit directly leading thereinto, and an opening extending through the flexible, air-impermeable envelope. A valve structure in the inlet/outlet tube is provided for controlling gas pressure within the cushion of foam for adjusting the firmness of the lumbar support means in the chair in a position accessible to a chair occupant. The valve structure includes a guide tube secured to the opening in the air inlet/outlet conduit.

Abstract: A chair comprises a seat portion and a support leg including a fluid pressure cylinder. The cylinder has vertically extending telescopic upper and lower sections which are movable between a closed position and an open position. The cylinder also has a valve release member to which an actuator is operatively connected. The valve release member is movable between a first position in which the valve release member is in a closed position and a second position in which the valve release member is in a open position. The actuator has an arm member pivotally mounted on a pivot with respect to the valve. An actuating button, which is positioned proximate the seat portion, is movable between a first position and a second position.
