Detail Specifications / Descriptions

Safety device with 3 levels backward adjustments. Chassis and backrest can lean backward together. The whole module is formed integrally. Instead of common device with 3cm, 2. 5cm, 2cm(outer, between, inner) lead to slip off easily, we set the module with 5cm, 4cm ,3cm (outer, between, inner), the vertical one is more reliable than the traditional semi-circle ones.
