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.
