Heavy Commercial Vehicle Driver Seat Assembly with Integrated 3-Point Safety Belt

This driver seat assembly is engineered specifically for commercial vehicles, featuring a fully integrated 3-point safety belt mechanism where the belt retractor is built directly into the backrest structure. Equipped with a single-side fixed armrest, an independent adjustable headrest, and basic fore-aft sliding and backrest recline manual controls, it can be configured with either a mechanical spring base or an air airbag floating suspension base. Compatible with the full range of Dongfeng heavy trucks, medium trucks, engineering dumpers, sanitation vehicles, truck-mounted cranes, and special modified vehicles, it serves as an ideal solution for OEM vehicle lines, aftermarket replacement upgrades, and export commercial vehicle fleets. Upholstered in durable all-black wear-resistant fabric, its integrated belt structure eliminates the need to drill upper pillar mounting points on the truck body, enabling faster installation and superior structural safety.
