Description

Technical Field

[0001] This utility model relates to the field of folding seat technology, specifically to a fiberglass seat with folding function. Background Technology

[0002] Foldable fiberglass seats are widely used in stadiums and other venues. Made of fiberglass, these seats are lightweight, high-strength, and corrosion-resistant. Their foldable design saves space when not in use, facilitating multi-functional use of the venue and greatly improving space utilization and flexibility in stadiums and other similar spaces.

[0003] However, existing folding chairs are susceptible to damage when exposed to strong winds. The wind blows the seat surface, causing it to swing back and forth. During this swinging motion, the seat surface constantly impacts the backrest. Over time, this can easily damage the seat components, affecting not only the normal use of the chair but also increasing maintenance costs and replacement frequency, thus limiting its functionality.

[0004] The torsion spring connecting the seat and backrest is the main reason why the seat is prone to swaying. The torsion spring acts as a restorative mechanism during seat folding and unfolding, but under external forces such as strong winds, its elasticity is insufficient to stabilize the seat, allowing it to rotate relative to the backrest. Furthermore, the existing structure lacks an effective fixing device, failing to securely hold the seat in place after it unfolds, further exacerbating the swaying phenomenon under wind conditions. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fiberglass seat with a folding function, which solves the problem that when facing strong winds, the wind blows the seat surface, causing it to swing back and forth and damaging the seat components.
