Injection Moulded Unupholstered Plastic Chair

摘要

A moulded plastic seat (31, 61, 131, 161) for a chair (30, 60, 130, 160) is disclosed. The seat is provided with a pair of recesses (37, 38, 57, 58, 67, 68) or a coalesced pair of recesses (137, 138, 157, 158, 167, 168) which are spaced apart and sized to reduce, but not eliminate, pressure on the ischial tuberosities of a sitter. A range of spacing and sizing corresponding to the height range of the sitter is disclosed. The seat is relatively thin and has some "give" in use. 3004FO-AI T tN t t A J r 5.;N '5 .-- ~-~'Y5%~' $ N'~' 'N NJ"'/NN N~ I N /NN ~ ~:;; "~ N I ~,N -. ~ ~s'5 I N" 'N I '' I / N I N" j I I ~ 'N / I N "N' '/ I 'N, N--'.
