Abstract
A chair has a supporting frame 1, a seat portion 101, a back portion 201 that has an upper end, a lower end, and is pivotally mounted relative to the supporting frame at a position above its lower end, and a recline mechanism 601. The recline mechanism 601 lifts the seat portion 101 upon a reclining action of the back portion 201, and has an operative connection 603, 611 between the seat portion and the supporting frame and a drag link 602 pivotally connected to the seat portion 101 and pivotally connected to the back portion 201 at a position below the pivotal mounting of the back portion relative to the supporting frame. As the back portion 201 of the chair is reclined, the lower end of the back portion 201 moves forward and the drag link 602 pulls the seat portion 101 upward relative to the supporting frame 1.
