Description

Technical Field

[0001] This utility model belongs to the field of flip-up seat technology, specifically relating to an electric telescopic movable grandstand front flip-up seat. Background Technology

[0002] In existing technologies, most seats used in large stadiums, conference venues, and screening rooms are fixed seats. After sports events or concerts, cleaning and sanitation are very inconvenient and consume a lot of manpower and resources. Although there are a few folding seats, they usually use folding mechanisms with additional springs. The spring mechanisms are complex, have high production costs, and are inconvenient to maintain, thus increasing the unit cost.

[0003] Chinese patent CN201139256Y discloses a flip-up seat for use in stadiums, conference venues, etc., which consists of a frame, a backrest, and a seat. The frame is composed of a back frame and a seat support frame. The seat support frame is made of tubing welded into an "L" shape, with one end welded to the back frame and the other end hinged to the seat. The backrest is fixed to the upper end of the back frame. The seat is composed of a plate, a reinforcing outer frame, reinforcing square tubing, and reinforcing angle steel. The hinge point between the seat and the seat support frame is located on the aforementioned reinforcing angle steel. This technical solution utilizes the fact that the center of gravity of the seat is located outside the hinge point. When the user stands up, the seat automatically flips, and the angle between the seat and the backrest is consistent. Each row of seats is neat and uniform, creating an aesthetically pleasing arrangement. In addition, because the seat automatically flips, the horizontal footprint of the seat is reduced, making it easier for spectators to enter and exit, especially in emergency situations, providing a passage for spectators to evacuate to a safe location.

[0004] The above technical solution solves the corresponding technical problem, but the flip-up seat in the above technology is not convenient for removing and installing the seat cushion, and it is not convenient to replace the seat cushion when it is damaged, which reduces its practicality.
