Abstract

A chair 2010 has a supporting frame 2011, a seat portion 2013, a back portion 2015, and a recline mechanism. The mechanism moves the seat portion 2013 upon a reclining action of the back portion 2015. The mechanism has a rear deformable member 2351 and a front deformable member 2353 operatively connecting the seat portion and the supporting frame. The recline mechanism also has a lower deformable member operatively connecting a lower part of the back portion and the supporting frame, and a puller member 2361 above the lower deformable member. The recline mechanism is configured such that as the back portion 2015 is reclined, the lower deformable member deforms and the puller member 2361 applies a rearward pulling action which causes the seat portion 2013 to move and the front and rear deformable members to deform.
