Component Specifications

Definition
Side rails are longitudinal structural members in seating module frames, typically positioned on both sides, designed to bear lateral loads, maintain frame geometry, and serve as mounting interfaces for seat mechanisms, upholstery, and accessories. They ensure dimensional stability and load distribution within the seating assembly.
Working Principle
Side rails function by transferring lateral and torsional forces through their rigid structure, distributing loads evenly to prevent deformation. They act as attachment rails for components like seat slides, recliners, and brackets, maintaining alignment and structural integrity under dynamic and static conditions.
Materials
Commonly made from cold-rolled steel (e.g., CR4, S355MC), aluminum alloys (e.g., 6061-T6), or high-strength polymers (e.g., glass-filled nylon). Surface treatments include powder coating, galvanization, or anodizing for corrosion resistance.
Technical Parameters
  • Length 500-1200 mm
  • Weight 2-5 kg
  • Thickness 1.5-3.0 mm
  • Load Capacity 150-300 kg
  • Mounting Holes M6-M10 threaded
Standards
ISO 9227, DIN 75201, ISO 14122

Frequently Asked Questions

What is the primary function of side rails in a seating module?

They provide lateral structural support, maintain frame alignment, and serve as attachment points for seat mechanisms and accessories.

Can side rails be interchangeable between different seating models?

Interchangeability depends on dimensional compatibility, mounting hole patterns, and material specifications; they are often model-specific.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
