Specifications & Features
Product Description
1. Product Overview
This seat backrest bracket is a core supporting component for seats of heavy trucks, light trucks, passenger buses, engineering dump trucks and other highway commercial vehicles. It connects the seat backrest to the seat base, bears all loads of the backrest and absorbs vibration shocks generated by bumpy roads, ensuring stable seat structure and quiet riding experience. Produced with integrated stamping and bending forming process, it is compatible with most mainstream OEM seats of commercial vehicles. Custom sizes and hole layouts are available for vehicle factory OEM supporting and aftermarket replacement.
2. Material & Manufacturing Technology
It is made of thickened Q235 high-strength carbon structural steel with plate thickness of 2.5mm–3.0mm to greatly boost overall load capacity. Full-automatic CNC stamping and one-piece bending forming are adopted without splicing welds to prevent fracture under force. Mounting holes are processed by CNC laser punching with hole position tolerance within ±0.02mm, perfectly fitting original seat installation positions. Reinforcing ribs are stamped on high-stress zones to disperse vibration stress and avoid cracking after long-term operation.
3. Surface Anti-Corrosion Treatment
Double anti-corrosion treatment is applied: electrophoretic primer plus outdoor electrostatic powder coating. The black electrophoretic layer fills tiny steel pores to block moisture penetration, while the outer high-temperature powder coating forms a compact protective film against rain, winter road deicing salt fog and construction mud. It passes more than 480 hours neutral salt spray test, resisting rust, peeling and paint loss under harsh coastal, rainy and construction environments.
4. Core Product Performance
- Ultra-high load-bearing capacity: The static bearing capacity reaches 120kg, fully supporting leaning and reclining postures without bending deformation on rough heavy-duty roads.
- Excellent anti-fatigue performance: It passes millions of cyclic vibration fatigue tests with no structural cracks or loose mounting holes, ideal for year-round high-intensity long-haul freight vehicles.
- Wide temperature adaptability: Stable performance from -40℃ to +85℃; no embrittlement in frigid northern winters, no deformation or abnormal noise under high-temperature exposure in southern summers.
- Vibration and noise reduction design: Multi-section buffer bending structure weakens vibration transmission over potholes and speed bumps, greatly eliminating metal rattling of the backrest and improving driving comfort.
- Fast non-destructive installation: Standard OEM hole layout allows direct assembly with original bolts without grinding, cutting or modification; single-person quick replacement is achievable.
5. Application Scenarios & Supporting Services
Applicable to long-distance tractors, muck dump trucks, urban sanitation lorries, medium cargo trucks, passenger coaches and other vehicles. Custom OEM laser marking and exclusive size mould opening are available. The MOQ of standard models is 50 pieces, with a lead time of 7–15 working days for regular orders. Each piece is packed with independent anti-rust wrapping for export carton packaging.

We’ve ordered these seat support brackets for our repair shop repeatedly. CNC precise holes match most commercial vehicle seats, installation takes only a few minutes. Thickened steel and reinforced ribs make them far more durable than cheap alternatives, customers never complain about deformation anymore. Great value for money.
Purchased a batch for our passenger bus fleet. Wide temperature resistance works great for both cold winter and hot summer. The double electrophoresis & powder coating prevents rust effectively. Stable load capacity supports passengers leaning comfortably, zero quality issues so far. Reliable supplier and premium product!
Great aftermarket replacement part! The bracket is made of thick solid steel with reinforced ribs, it won’t warp under heavy pressure. The electrophoretic and powder coated surface resists road salt and mud perfectly. OEM standard hole design saves lots of installation time, my truck clients all give positive feedback. Will place bulk orders again soon.
