Description

Electric sofa equipped with a mattress having a folding slope {electromotion type sofa mattress with tilt angle}

The present invention relates to an electric sofa equipped with a mattress having a folding inclination part, and more particularly, so that the mattress placed on the top of the folding frame of the sofa can be naturally folded and unfolded according to the folding and unfolding operation of the folding frame. Of course, it prevents the folded part of the mattress from being exposed to the outside in the folded state, and the position of the headrest provided in the mattress can be changed to suit the user's physical condition, and the headrest can be prevented from moving left and right. It relates to an electric sofa equipped with a mattress having a folding inclination part to be able to do so.

In general, theaters where you can watch movies are divided into general grandstands and VIP grandstands. In general, general grandstands are cheaper than VIP grandstands, so to accommodate a large number of spectators, there are legs on the floor of the grandstand where the chairs are tiered. Most of them are fixedly installed, and these chairs spread out the seat rotatably coupled to the legs and then sit on the seat to watch a movie, and are continuously installed next to each stairway in the grandstand.

In addition, each individual chair seat and backrest are partitioned by a leg placed in the middle, and an armrest of a chair is installed at the upper end of the leg so that a viewer can place an arm on the armrest while watching a movie.

On the other hand, the VIP audience seats are smaller than the general audience seats, but because the viewing cost is high, a sofa is installed so that the audience can sit comfortably and watch the movie.

The sofa installed in such a VIP grandstand is equipped with a seat on which the visitor sits, a backrest on which the viewer's back is supported, as well as a headrest on which the viewer's head is supported, and the armrest on which the viewer's arm hangs is provided with a cushion. .

Furthermore, in recent years, in order to allow viewers to watch a movie in a more comfortable state, the recliner sofa has been developed, with the backrest reclined and the legrests raised so that viewers can comfortably watch a movie with their legs extended on the legrests. is being used

As an example of the prior art of such a recliner sofa, the recliner sofa in which the angle of the headrest is adjusted has been devised, which is Patent Publication No. 10-2018-0015951, which is based on the buttocks by the operation of the recliner device when the button is pressed. In the recliner sofa operated so that the user can rest in a lying state while the backrest is moved backward and the legrest is raised, the headrest is separately installed on the upper part of the backrest to move, and the headrest and the backrest are angle adjustment tools When the user pulls the headrest horizontally connected to the backrest to face the front, the headrest rotates based on the angle adjuster and bends in multiple stages. At the same time, the bent state is maintained by the locking structure of the angle adjuster. , The back of the headrest and the backrest are connected by an elastic band, and when the headrest is bent forward as much as possible, the locking structure of the angle adjustment tool is released, and at the same time, the headrest is moved to the rear by the restoring force of the elastic band and placed horizontally with the backrest again. made to work.

However, in the recliner sofa of the prior art, since the buttock cushion part, the backrest cushion part, and the legrest cushion part are provided in a state where they are integrally fixed with the frame body, the buttock cushion part, the backrest cushion part, and the legrest cushion part are washed And there is a problem that the cleaning operation is not easy.

In addition, since the buttock cushion part, the backrest cushion part, and the legrest cushion part are provided spaced apart from each other for easy folding and unfolding by the driving body, a gap is generated between the buttockrest and the backrest and the legrest. There is a problem in that foreign substances are introduced into the side, and contamination is easily generated.

Moreover, although the angle of the headrest is adjusted, there is a problem in that a separate headrest must be provided according to the user's physical condition.
