The patent abstract indicates that this invention relates to an intelligent headrest system, aiming to provide personalized comfortable support by real-time monitoring of posture information such as the passenger’s sitting posture, head tilt angle, and body-feature characteristics. The system includes an OMS sensor, an in-vehicle control module, and an intelligent headrest module. The OMS sensor is used to monitor the passenger’s sitting posture and posture information in real time. The in-vehicle control module is connected to the OMS sensor and is responsible for receiving and transmitting this posture information. The intelligent headrest module is connected to the in-vehicle control module and includes multiple independently controllable inflatable airbag units and an airbag adjustment unit. The in-vehicle control module transmits the monitored posture information to the intelligent headrest module in real time. The intelligent headrest module then triggers the airbag adjustment unit based on the received posture information, thereby adjusting the inflation amount of each inflatable airbag unit to provide the best head support and comfort. The system can automatically adjust the headrest support effect according to real-time changes in the passenger’s posture, significantly improving comfort and safety during long-distance driving.
