The present invention relates to a frame structure of an electric sofa that not only reduces production cost but also greatly improves workability and firmly supports an upper body support.

In general, theaters where you can watch movies are divided into general audience seats and VIP seats. Since general audience seats are generally cheaper than VIP seats, legs are placed on the floor of the audience seats where chairs are stepped in order to accommodate a large number of spectators. Most of these chairs are fixed and installed, and after unfolding the seat rotatably coupled to the leg, the chair sits on the seat to watch a movie, and is continuously installed next to each stairway of the audience seat.

In addition, each individual chair seat and backrest are partitioned by legs placed in the middle, and armrests of the chair are installed at the upper ends of the legs so that viewers can place their arms on the armrests while watching a movie.

On the other hand, the VIP seats accommodate fewer spectators than the general seats, but because the cost of viewing is high, a sofa is installed so that the spectators can sit in a comfortable state and watch the movie.

The sofa installed in these VIP seats is equipped with a seating area for spectators to sit on, a backrest for supporting the spectator's back, as well as a headrest for supporting the spectator's head, and an armrest for the spectator's arms to hang is provided to have a cushion. .

Moreover, recently, in order to allow viewers to watch a movie in a more comfortable state, the backrest is tilted back and the legrest is raised so that the viewer can put their legs on the legrest and comfortably watch the movie in an outstretched state. It is being used.

However, in the case of a conventional sofa, since the hip cushion part, the back cushion part, and the leg rest cushion part are provided in a spaced state from each other so that they can be easily folded and unfolded by the driving body, there is a gap between the buttock, the backrest, and the legrest. There is a problem in that foreign matter is introduced into the generated gap and easily contaminated.

In order to solve the problems of the prior art, the present applicant has devised a motorized sofa equipped with a mattress having a folding slope, registered in Patent No. 10-2275795, which has a support frame body having a driving body on the inside and both ends of the support frame body. On the upper surface of the armrest body and the support frame body, which are located on the top of the armrest body and the support frame body, are connected to the driving body and receive power from the driving body, and are folded and unfolded by a plurality of hinge parts. In the electric sofa including a mattress seated and having a backrest, buttrest, thigh and legrests, the lower surfaces of the backrest, buttock, thigh and legrests of the mattress are respectively folded frame body and It is in close contact with each other and is folded and unfolded by the folding and unfolding operation of the folding frame body, and the backrest, buttock, thigh, and legrests of the mattress correspond to a plurality of hinges provided in the folding frame body, respectively. A plurality of folded parts are provided, and blocking parts are provided to block the upper surface of the plurality of folded parts so that foreign substances are prevented from being exposed to the outside, and the backrest, buttock, and thighrests of the mattress are provided. And the legrests are gathered when folded and spread when unfolded, and extend from the lower end of the plurality of folded parts so that the folding operation of the folded parts is not interfered with when the backrest, buttock, thigh, and legrests of the mattress are folded. Folding inclined portions inclined in symmetrical directions with respect to each other are respectively provided.

In this prior art, a folding inclination portion is provided on the folding portion of a mattress of an electric sofa having a folding and unfolding mattress to prevent the folding portion from being exposed to the upper surface of the mattress, and interference with folding and unfolding of the mattress is prevented by the folding inclination portion. I am expecting an unreceived effect.

However, in the prior art devised by the present applicant, since the frame structure for folding and unfolding the back, hip, thigh and leg supports, respectively, is complicated, assembly workability is lowered and productivity is lowered accordingly. There is a problem.
