Dongfeng Kinland truck parts Front left armrest assembly with hinge 8211519-C0100

Crafted with long-haul truck driving comfort in mind, this armrest assembly features an ergonomic curved surface that conforms to the natural shape of a driver’s arm, reducing muscle fatigue during extended periods of operation. The armrest pad is filled with high-density polyurethane foam (25mm thick) that balances softness and support—providing sufficient cushioning to relieve pressure on the elbow and forearm while maintaining shape retention even after years of use. The hinge allows the armrest to rotate 120° (from vertical to horizontal), enabling drivers to adjust it to their preferred angle: horizontal for resting during steady driving, or vertical to free up space when entering/exiting the cab or operating the gear shift. Additionally, the armrest’s height (adjustable via the seat’s existing mechanism) aligns with the truck’s steering wheel and control panel, ensuring the driver’s arm remains in a relaxed, neutral position, which minimizes strain on the shoulder and wrist. This focus on ergonomics directly addresses the comfort needs of Dongfeng Kinland drivers who spend hours on the road daily

Built to withstand the rigorous conditions of heavy-duty truck use, the armrest assembly uses high-performance materials for long-term durability. The outer shell and hinge bracket are made of glass fiber-reinforced PA66 nylon plastic, which offers excellent tensile strength (≥75MPa) and impact resistance—preventing cracking or deformation from accidental bumps (e.g., when loading/unloading tools) or vibration during off-road driving. The armrest pad’s surface is covered with wear-resistant PVC leather that resists scratches, oil stains, and fading: it can withstand 50,000+ friction cycles (per ISO 105-X12 standards) without peeling, making it easy to clean with a damp cloth. The hinge’s pivot pins are made of galvanized steel, which resists rust and corrosion caused by moisture, road salt, or cab humidity—ensuring smooth rotation even in harsh weather conditions. All materials comply with automotive interior safety standards, containing no harmful substances (e.g., heavy metals, formaldehyde) and maintaining structural stability across a wide temperature range (-30℃ to 80℃), suitable for both hot summer and cold winter driving

The integrated hinge is a core component of this assembly, designed to provide reliable rotation and secure positioning for the armrest. It features a dual-pivot structure with precision-machined steel pins and self-lubricating nylon bushings, which reduce friction and eliminate squeaking noises during adjustment—ensuring quiet operation even after thousands of uses. The hinge includes a built-in detent mechanism that locks the armrest in 3 key positions (0°, 60°, 120°), preventing it from sliding or rotating unexpectedly while the truck is in motion. This locking function is critical for safety: it keeps the armrest stable during bumpy rides, avoiding distractions or interference with the driver’s control of the vehicle. The hinge bracket is securely fastened to the armrest shell and seat frame via 4 high-torque screws (M6×10), which resist loosening from vibration—common in heavy-duty trucks. Additionally, the hinge undergoes 10,000+ cycle tests (opening and closing) to verify durability, ensuring it maintains performance without wear or failure for the lifetime of the Dongfeng Kinland truck

Designed for hassle-free installation and maintenance, this armrest assembly requires no specialized tools or professional skills—allowing Dongfeng Kinland operators or repair shops to complete replacement quickly. The package includes all necessary hardware: 4 mounting screws (matching the original seat’s thread size) and a small Phillips screwdriver for easy attachment. Installation steps are straightforward: first, remove the old armrest by unscrewing the hinge bracket from the seat frame; then, align the new assembly’s hinge with the seat’s mounting points; finally, tighten the screws and test the armrest’s rotation and locking function—all completed in 15 minutes or less. Maintenance is equally simple: the PVC leather surface can be wiped clean with mild detergent to remove dirt or oil, and the hinge can be occasionally lubricated with silicone spray (if needed) to maintain smooth operation. Unlike aftermarket armrests that require modifications, this assembly’s direct-fit design and easy setup minimize truck downtime—critical for commercial truck operators who rely on their Dongfeng Kinland vehicles for daily logistics and transportation tasks
