Relieve pressure. Bus seats are basically made of plastic, which is tough and can expand slightly when under pressure. If this small hole is not opened, the seat will be under too much pressure and the middle part will sink; with this hole, there is more space for expansion and the pressure is relieved, so that even if there is a large flow of people every day, the seat will not be scrapped so quickly. Ventilation and cooling. As we all know, plastic has poor heat dissipation performance. It is easy to get your butt burned when riding a bus. Opening a small hole in the seat can increase the fluidity of the airflow, improve the heat dissipation efficiency of the seat, and give passengers a more comfortable experience. In addition, the small hole can also prevent the seat from being damaged by thermal expansion and contraction due to temperature changes. Convenient to manufacture. When manufacturing, the plastic seat is formed in one second by pressing the mold. Because the molded chair has a small hole, a steel pipe can be passed through it, making transportation easier. Easy to clean. The bus seats are near the windows and are easily wetted by rain on rainy days. In addition, there may be water accumulation when cleaning the seats. With this small hole, the water can flow down and dry faster without affecting the use. To sum up, although the hole on the bus seat is small, it actually plays a very important role.
