Automotive Rear Center Seat Armrest Internal Load-Bearing Frame Assembly
This component serves as the core internal load-bearing frame for rear seat center armrests, constructed from a one-piece stamped cold-rolled steel plate structure. Pre-embedded inside the PU armrest foam, it acts as the primary structural matrix for the rear armrest. It handles fold-down/fold-up rotation, supports arm pressure, integrates cupholder mounting, provides lock positioning, and housing hinge pivot assemblies. This ensures smooth armrest rotation and load-bearing performance without deformation, making it widely applicable for fold-down rear center armrests in sedans and SUVs.
-
Static Load Resistance
Withstands 150 kg static load applied to the center when horizontally deployed with zero permanent plastic deformation.
Anti-Sagging Durability
Prevents long-term sagging or collapse under daily arm resting and heavy object placement.
Opening & Closing Cycles
10000 cycles or higher of overall folding tests.
Hinge Stability
Zero hinge hole enlargement or deformation; Reliable locking structure prevents automatic loosening or sagging during road vibrations.
Temperature Range
Operating range -40 to 90 degrees C; Plating layer resists peeling and rusting in high/low temperatures and humid cabin environments.
Thermal Expansion Fit
Pre-embedded inside PU foam matrix without squeaking or noise caused by temperature changes.
Contour Compatibility
Outer contour matches foam molding dies; Ensures tight bonding between injected skeleton and PU foam.
Vibration Noise Elimination
Prevents internal metal-on-metal friction and clashing noise during vehicle operation.
