Overview
Power seats, heating, and massage functions require flexible wiring that survives constant articulation at the seat track and recliner mechanism without fatigue failure.
Design & Construction
Flex-Rated Conductor Construction
Fine-strand, high-flex conductors are rated for the repeated bending seen at seat track and recliner hinge points across hundreds of thousands of cycles.
Heater Mat & Motor Connector Integration
Purpose-matched connectors interface directly with seat heater mats, lumbar motors, and memory module electronics, simplifying seat assembly line integration.
Manufacturing Process
Built under IATF 16949 process controls with flex-cycle and continuity testing on every harness, supporting seat system suppliers across sedan, SUV, and luxury trim programs.
Typical Applications
- Power seat motor wiring
- Seat heater mat cabling
- Lumbar support and massage function harnesses
- Seat memory module interconnects
- Occupancy sensor wiring
Common installations include Power seat motor wiring, Seat heater mat cabling, and Lumbar support and massage function harnesses, where vibration resistance and long-term durability under continuous thermal cycling are the primary design drivers. The same base design can also be adapted for Seat memory module interconnects and Occupancy sensor wiring with minor changes to connector type or cable length.
