Provide a detailed introduction to the structural details of auditorium chairs.
Mar 04,2022
There are requirements regarding the structure and standing legs of auditorium chairs that everyone should be aware of. There are six key details in total, which can be reasonably arranged to address these issues and situations. The details are as follows: The chair frame is made of high-quality birch plywood, molded and cold-pressed using a mold, with an environmentally friendly polyester matte finish on the surface. The base feet: ventilation hole steel plates are made of national standard cold-rolled steel plates with a thickness of 2.3mm, stamped and formed.
Sponge: The seat and backrest use polyurethane cold-foam one-time molding. Seat and back shell: made of high-quality birch plywood, hot-pressed in one piece, with an environmentally friendly polyester matte finish on the surface, smooth and delicate. Fabric: The seat and back fabric is made of linen, flame retardant, stain resistant, and fade resistant. Return function: The seat cushion uses an adjustable damper return device, which can adjust the speed of the seat cushion returning. The auditorium chair includes structures that flip without noise.
Auditorium chairs are mainly divided into two types: single-leg floor-mounted (single-leg floor) and armrest standing leg floor-mounted (standing leg directly connected to the armrest frame). They are also divided into aluminum alloy and steel iron frames. Compared to these two types of standing legs, aluminum alloy appears more high-end and avant-garde. The single-leg floor-mounted chair supports the center point of the seat with the standing leg. Besides its aesthetic appeal, it also facilitates connecting the chair legs with other environmental facilities such as ventilation outlets and power interfaces. Because the connection method of the single leg is relatively complex, the cost of the single-leg structure is correspondingly higher.
The method of armrest standing leg floor mounting is solid, reliable, and convenient for fixing and installation. The armrest frame is combined with the standing leg, and the structure is simple. The standing leg is the foundation supporting the auditorium chair and is generally fixed directly to the ground with anchor bolts. In places where ground fixing is not allowed or where frequent position changes are required, movable feet or chairs equipped with movable foot frames need to be used.
