Keep pressing the button and press it back on the seat back!
Some bus seats have front, rear, left and right arrow buttons. This allows the inclination of the backrest to be adjusted. As shown below:
The left and right direction buttons are used to adjust the left and right movement of the seat. When you press the button, you can move the seat a little distance to the corridor, making the distance between the next seats more spacious. The front and rear direction buttons adjust the inclination of the seat back. When the button is pressed, the back is back and the seat back is tilted backward. Not all bus seats have such buttons, because they bring convenience and comfort to themselves, and may cause inconvenience to others.
