Automobile seats are constantly being innovated. Nowadays, many vehicle models are already equipped with seat heating and ventilation functions, and high-end models even come with massage seats. Mercedes - Benz has recently obtained a patent, introducing a new head massage function to its seat system. This is a further expansion of existing technologies and helps relieve the stress of drivers and passengers. Its mechanical structure is complex and can identify the height and head position of drivers and passengers through sensors and adjust the angle accordingly. The design plan is to install a central module inside the headrest, which is connected to massage arms with adjustable struts. This device can rotate to cover the entire head area. The system is driven by a motor and supports multiple starting methods. Users can also customize the adjustments. This patent represents an upgrade to Mercedes-Benz's seat massage function. Although it may not necessarily be put into mass production, it can serve as a differentiated advantage against competing products.
