Claims

[Scope of utility model registration request]

In an easy chair, a backrest frame is pivotally attached to a seat frame so as to be freely tiltable, and the backrest frame is held at a variable angle by an expansion/contraction actuation device such as a gas spring. An inverted U-shaped head rest frame is pivotally attached to the upper end of the backrest frame so as to be swingable in the front and back direction, and the both side frames are formed from a pair of opposite side frame parts, and are pivotally connected to the upper end of the backrest frame so as to be able to swing freely in the front and rear directions. At a more rearward position, the bearing pieces are connected to each other through a horizontal rod part that has a rearwardly projecting bearing piece fixed to the central part, while the left and right lower ends of the headrest frame are connected to the rearwardly protruding bearing pieces that are fixed to the central part of the frame. A link is connected to the bearing piece of the horizontal rod of the headrest frame and the link that always maintains the relative angle between the headrest frame and the backrest frame constant regardless of the tilting of the backrest frame. An easy chair characterized by being provided between a bearing piece of a horizontal rod part of a seat frame.
