What structures do auditorium chairs have?

Auditorium chairs are mainly composed of four parts: seat, backrest, armrest and foot. Usually, the foot and armrest are combined to form a firmly installed armrest. The combined structure is generally a steel-wood structure or a steel-plastic structure.

1. Auditorium chair standing

There are two landing methods: single-foot landing (single-foot landing) and armrest landing (the standing foot is directly connected to the armrest).

The single-foot landing seat and the standing foot supporting the center point of the seat are not only beautiful, but also convenient for connecting the seat foot with other environmental facilities, such as ventilators, power interfaces, etc. Because the connection method of the single-leg mechanism is more complicated, the cost of the single-leg mechanism is also increased accordingly.

The armrest landing method is firm and reliable, the fixed installation is convenient, and the armrest and foot combination structure is simple.

The standing foot is the basis of the auditorium seat. Generally, the anchor bolt is directly fixed to the ground.
