Patent ID: 8172315

Claim:
A reclining chair or functional sofa comprising: a back support; a seat part; a headrest; a lower back support; a frame part, wherein the back support is rotatable around a stationary and horizontal axis relative to the frame part; a support part; a connection joint structurally configured to connect a lower end of the back support with the seat part; a guide structurally configured to cooperate with the connection joint to displace the seat part forward and backward relative to the frame part when the back support rotates forward or backward; and two arms fixed to the frame part and extending downward from the stationary horizontal axis toward the lower end of the back support when the back support is in an upright position, each of the two arms being shorter than a distance from the horizontal axis to the lower end of the back support, wherein the lower back support is rotatably fixed between lower parts of the arms, and wherein an angle between the arms and the back support is small when the back support is in the upright position, whereby the lower back support provides a distinct lower back support to a user, and the angle is configured to gradually increase as the back support rotates backward and moves the lower part of the back support away from the lower back support, whereby the distinct lower back support provided to the user gradually decreases as the back support rotates backward from the upright position.
