Automatic sofa

Abstract

An automatic sofa is disclosed. The automatic sofa of the present disclosure includes: a main body having a back support body; a seat actuator disposed on the main body; and a seat unit disposed on the main body and connected to the seat actuator to move, wherein the seat actuator comprises a driving motor disposed on the main body, a sliding body disposed on the main body to be connected to the driving motor and configured to slide forward/backward with respect to the main body, a seat coupling body connected with the sliding body to move with the sliding body and coupling the seat unit thereto, and a rotary unit coupled at a first side to the main body, coupled at a second side to the seat coupling body, and configured to guide movement of the seat coupling body.

What is claimed is: 
     
         1 . An automatic sofa comprising:
 a main body having a back support body;   a seat actuator disposed on the main body; and   a seat unit disposed on the main body and connected to the seat actuator to move,   wherein the seat actuator comprises a driving motor disposed on the main body, a sliding body disposed on the main body to be connected to the driving motor and configured to slide forward/backward with respect to the main body, a seat coupling body connected with the sliding body to move with the sliding body and coupling the seat unit thereto, and a rotary unit coupled at a first side to the main body, coupled at a second side to the seat coupling body, and configured to guide movement of the seat coupling body.   
     
     
         2 . The automatic sofa of  claim 1 , wherein the rotary unit comprises:
 a link member coupled at a first side to the seat coupling body and configured to horizontally move with the seat coupling body;   a rotary body coupled at a first side to the link member and configured to push a rear of the seat unit by rotating when the link member is moved; and   a rotary arm coupled to a second side of the rotary body and configured to support the rotary body, and   when the rotary body is rotated, the rotary arm is also rotated in the same direction as a rotation direction of the rotary body.   
     
     
         3 . The automatic sofa of  claim 2 , wherein the rotary unit further comprises a coupler rotatably coupling the rotary arm to the main body. 
     
     
         4 . The automatic sofa of  claim 1 , wherein the seat actuator further comprises guide rails disposed on the main body and configured to guide slide movement of the sliding body. 
     
     
         5 . The automatic sofa of  claim 1 , wherein the seat unit comprises:
 a base seat coupled to the seat coupling body, configured to move with the seat coupling body, and provided as a part on which a user sits;   base supports coupled to the base seat and configured to support the base seat; and   roller members disposed at the base supports and configured to guide movement of the base supports.
