Abstract

A passenger car sitting and lying dual-purpose functional seat, which is composed of front row seats and rear row seats; the front row seats include front row left and right columns, front backrests, front row up and down seat cushions, front row armrests, and two front support seats , two front connecting plates and the front hinge pivot around which the front backrest can rotate; the rear seat includes the rear ladder, the rear left column, the rear beam connecting the rear ladder and the rear left column, the rear backrest, the rear Rows of seat cushions, rear armrests, two rear support seats, a rear hinge support shaft that allows the backrest to rotate freely, and a guide groove that is arranged on the side of the rear backrest so that it can move up and down along the rear hinge support shaft. The rear seat of the present invention has increased the ladder for the upper and lower sleepers and the guide groove on the side of the backrest. When needed, the front backrest and the upper and lower cushions of the front row can form an upper sleeper, and the backrest and the upper and lower cushions of the rear row can form a lower sleeper.
