AI Technical Summary
Existing car seat belts tend to become stiff and twisted over long-term use, making them difficult to pull. They are also uncomfortable in hot environments, which may cause rashes. Furthermore, they can cause shoulder marks and lumbar pressure during long-distance driving, affecting both safety and comfort.
The seat belt uses a graphene composite film as a component, including a protective layer, a graphene film, an aramid fiber skeleton network, and an adhesive/buffer layer. It is formed by roll pressing or hot pressing and equipped with a flexible electronic control unit and a conductive/impedance type thin film damage sensor to achieve heat conduction, heat equalization, and real-time monitoring functions.
The seat belt has improved softness and comfort, reduced rashes caused by friction, and ensured safety and comfort by monitoring the seat belt status in real time through conductive layers and sensors. It also provides heat dissipation, especially in high-temperature environments, reducing shoulder marks and lumbar pressure.
