Abstract: Method and apparatus for quickly, and substantially uniformly, heating and cooling a bed of polymeric fibers having high melting point and low melting point fibers therein for softening the low melting point fibers and bonding them to the high melting point fibers to form a seat cushion. Hot and cool gases are flowed through the bed of fibers to effect the heating/cooling.

Abstract: Method and apparatus for quickly, and substantially uniformly, heating and cooling a bed of polymeric fibers having high melting point and low melting point fibers therein for softening the low melting point fibers and bonding them to the high melting point fibers to form a seat cushion. Hot and cool gases are flowed through the bed of fibers via a plurality of ventilator spikes extending into the fibers in the mold cavity to effect substantially uniform gas flow rates through the fibers for quick more uniform heating/cooling of the fibers.

Abstract: Mechanical massaging device incorporated in the back rest of a seat or other supporting equipment that has a pair of cross shafts operatively mounting paired rolling massaging wheels that can be selectively positioned and rotated to produce massaging through suspension fabric on the body of a person supported thereon. The massaging device has three centralized input shafts extending longitudinally within the confines of a cavity in the back rest or other support which are selectively driven by user controlled motors remote from the massaging wheels. The lateral spacing of the massaging wheels as well as their rotation can be adjusted. The massaging wheels can be selectively positioned at an infinitely number of vertical positions within the cavity to provide massaging action for enhancing the supply of blood to supported body areas under pressure of body weight.
