Abstract: A panel structure comprises a frame members defining the perimeter of the panel structure. The frame members have a first side facing outwardly of the panel structure and an opposed side facing inwardly. A panel member extends between the frame members and is engagable therewith. The panel member comprises an inner honeycomb core constructed from cellulosic material and having a pair of opposed side faces and a pair of opposed side panel members having a first side facing outwardly of the panel structure and an opposed side facing inwardly. Each of the opposed side faces is affixed to a respective side of the honeycomb core. The side panels are constructed essentially from material which, when not affixed to the honeycomb core, is non-structural and, when affixed to the honeycomb core, has a tensile strength sufficient to prevent compressive movement of the opposed side of the honey comb core.

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 support device for supporting the forearm of a worker in a generally horizontal plane comprising:(a) an attachment member for affixing the support device to a support member;(b) a lower support member having a forward end and a rearward end, the rearward end being pivotally mounted to the attachment member for free pivotal rotation of the forward end of the lower support member within an arc with respect to the attachment member due to force applied to the lower support member when the arm of the worker is moved in the horizontal plane; and,(c) an upper longitudinally extending support member for supporting the forearm of a worker, the upper member having a forward end and a rearward end, the upper support member being slidably mounted on the lower support member for movement of the upper support member in the longitudinal direction between a recessed position and an extended position with respect to the lower support member due to force applied to the upper support member when the arm of the worker is move

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.
