The Importance of Seat Hinge Wiring in EVs
In modern EV designs, seats are no longer static—they’re dynamic modules filled with motors, heating systems, airbags, and occupancy sensors. The wiring that powers
these features often runs through or around the seat hinge, a highly mobile and abrasive area.
Without proper protection, this wiring is exposed to:
Constant movement and bending
Abrasion from metal joints
Risk of insulation damage
Electrical interference or signal failure
Protecting these wires is not just about safety—it's about reliability, comfort, and performance over the full life of the vehicle.
Why PET Braided Sleeving is the Best Choice
Polyethylene Terephthalate (PET) braided sleeving is engineered to withstand the physical and environmental demands of automotive interiors. Here’s why top automotive
manufacturers are choosing it for seat hinge applications:
High Flexibility: It expands and contracts with the movement of the seat.
Superior Abrasion Resistance: Protects against friction and sharp edges.
Clean Finish: Gives a tidy, professional look that matches OEM expectations.
Noise Dampening: Reduces annoying rattling or rubbing noises—especially important for premium EVs.
Heat and Chemical Resistance: Withstands automotive-grade temperatures and exposure to oils or cleaners.
PET braided sleeving is commonly used for:
Seat motor wiring
Heating pad and lumbar support cables
Airbag deployment wires
Sensor lines routed through hinges
By using braided sleeving, manufacturers reduce warranty claims, improve installation efficiency, and enhance the user experience.
