    • A chair (10) includes spaced frames (11, 12) each of which have a lower portion (13, 14) and an upper portion (15, 16). The upper (15, 16) and lower (13, 14) frame portions are interconnected by curved portions (17, 18) which extend upwardly and inwardly from the lower frame portions (13, 14) to the upper frame portions (15, 16) so that the lower frame portions (13, 14) are spaced from each other further than the spacing of the upper frame portions (15, 16). A seat (21) is carried by the upper frame portions (15, 16), and caster assemblies (42) are carried by the lower frame portions (13, 14). Spreader bars (36, 37) extend between and attach the lower frame portions (13, 14) to each other. A tray (30) is carried by the lower frame portions (13, 14) and has opposed edges (32, 33) which are received around the lower frame portions (13, 14).
    • 椅子(10)包括间隔开的框架(11,12),每个框架具有下部分(13,14)和上部部分(15,16)。 上部(15,16)和下部(13,14)的框架部分由从下部框架部分(13,14)向上和向内延伸到上部框架部分(15,16)的弯曲部分(17,18)相互连接 ),使得下框架部分(13,14)彼此间隔开比上框架部分(15,16)的间隔更远。 座架(21)由上框架部分(15,16)承载,脚轮组件(42)由下框架部分(13,14)承载。 撒布杆(36,37)在下框架部分(13,14)之间延伸并相互连接。 托架(30)由下框架部分(13,14)承载,并且具有围绕下框架部分(13,14)容纳的相对边缘(32,33)。
