摘要： A chair having a seat and a back rest comprises a fluid-containing cushion in the back rest that provides passive automatically adjustable support for the user's lumbar region. The cushion can comprise one or more fluid-containing chambers encompassing the areas of the user's upper back and lumbar regions. As the user leans backs, fluid is forced from the regions adjacent the upper back down to the lumbar region to provide enhanced lumbar support to the user.

摘要： A horizontally adjustable armrest for a chair including a vertically slideable element having a base, a lower horizontal slide element movable longitudinally, an upper horizontal slide element movable laterally and an armrest cover. The lower horizontal slide element includes a longitudinally extending slot with a shoulder. Two fasteners extend through the slot and are fastened to the base. Under the fasteners' heads are springs and washers to bias the lower slide element into frictional engagement with the base. The upper surface of the lower horizontal slide element includes a pair of guide rails which are received in recesses formed in the bottom surface of the upper horizontal slide element. The upper slide element includes two slots extending perpendicular to the slot of the lower slide element. Fasteners, springs and washers are used to bias the upper slide element into frictional engagement with the lower slide element. An armrest cover fits over the horizontal slide elements.
