Background technique

With the development of society, people's quality of life has gradually improved, and gradually changed from food and clothing consumption to enjoyment consumption. The demand and requirements for daily household items have become more and higher. Among them, row chairs are more common in public places. A seat with high space utilization is placed in the waiting halls of cars, trains, and airplanes to provide passengers with a rest. However, most of the seat rows have a single and inflexible structure, and the overall structural specifications only meet some people. In most cases, the size of row chairs cannot be adjusted, which makes the "high space utilization rate" of row chairs more tasteless; another example is a Chinese patent document with application number CN201620113563.6, which discloses a multifunctional waiting row chair , although this technology realizes the multi-functionality of row chairs, there are also problems. First, when the mobile phone holder and table board are used at the same time, the derived structure of row chairs will become more and more complicated, so that the occupants are limited in the unit space and cannot Making relatively large movements restricts his personal freedom to a certain extent. Secondly, the mobile phone holder on the middle armrest is located between the two seats, which cannot satisfy the situation that people on both seats need to use the mobile phone holder. , and when the people on one side use the mobile phone holder, it will affect the rest of the occupant on the other side, which will affect the rest purpose of the occupant.

Contents of the invention

The purpose of the present invention is to provide a comfortable row of chairs. Through the adjustability of the position of the armrests, the space utilization rate of the row of chairs can be improved while simplifying the structure of the row of chairs, so that the passengers sitting on adjacent seats do not affect each other, creating a A real, relatively independent rest space.

The above-mentioned technical purpose of the present invention is achieved through the following technical solutions: a comfortable row of chairs, including a seat board, a back board, an armrest and a footrest, and the back board and the footrest are connected to the seat board respectively, wherein , the armrest includes a bracket and a moving rod, and the seat board has a lateral slide groove and a positioning surface near the side of the back plate, and the connecting rod includes an exposed part and an embedded part, and the horizontal slide groove It is a rectangular strip-shaped hollow groove extending in the horizontal direction and running through the two sides of the seat plate. The positioning surface is a plane extending from the edge of the notch in the direction of the horizontal slide groove close to the bracket. The inner part is a circular thin piece limited by the positioning surface in the horizontal slide groove, and the exposed part connects the inner part and the end of the bracket near the side of the backing plate.
