The invention relates to a method for unlocking and / or locking at least one reeling mechanism (1) for a belt of a safety belt which corresponds to a vehicle seat (2) of a motor vehicle (3), wherein the reeling mechanism (1) comprises an electrically operable belt pull-out lock which, in an unoperated, current-free state, engages to prevent the belt from being pulled out of the reeling mechanism (1). Here, based on the recognition of at least one activation event, after the activation of a control device (5) for controlling and / or regulating the detection and / or a sensor arrangement (6) for carrying out the detection, at least one unlocking event is detected which causes the reeling mechanism (1) to be unlocked by operating the electrically operable belt pull-out lock (4) only. The control device (5) is here transferred from a rest state into an operating state by the activation event.

This invention discloses a molten salt energy storage system and its operation method for thermal power plants coupled with compressed carbon dioxide energy storage, belonging to the field of energy storage and peak shaving in thermal power plants. The system includes a molten salt energy storage unit and a compressed carbon dioxide energy storage unit: molten salt is heated by extracted steam after reheating for heat storage; the heat of compression generated by the compressed carbon dioxide is used to heat feedwater and condensate, eliminating the need for an independent heat storage medium; before expansion, carbon dioxide is heated by four stages of extracted steam and high-temperature molten salt, and cold energy recovery is used to liquefy the carbon dioxide in a circulating manner; the operation method includes peak shaving and load reduction operation modes and peak shaving and load increase operation modes. This invention can improve the peak shaving response speed and regulation capability of thermal power plants, increase electricity-to-electricity efficiency by more than 20%, eliminate the need for cooling water and an independent heat storage medium, reduce investment, achieve energy cascade utilization and decoupled operation of compression and expansion, enable boilers to maintain high loads to achieve zero grid connection electricity, avoid frequent start-ups and shutdowns, and extend equipment life.
