The present invention provides an oil slurry filter, a filter unit including the oil slurry filter, a multiple-filter system including the oil slurry filter, and a multiple-stage filter system including the oil slurry filter. Due to the use of the filter component of flexible texture in the oil slurry filter of the present invention, the problems that the filter material is easily blocked by high-viscosity colloidal impurities, the regeneration efficiency of the filter is poor and the filtration efficiency is low are solved, and it is possible to make the backwash treatment of the filter residue more convenient and improve the regeneration efficiency of the filter. The present invention also provides a filtering process using the oil slurry filter to ensure long-term stable operation of the oil slurry filtering process.

A safety belt retractor, a vehicle safety belt with the safety belt retractor and a vehicle with the vehicle safety belt are provided. The safety belt retractor is provided, on an end segment thereof, with a pre-tensioning, force-limiting and decoupling device that comprises a safety belt reel (), a driving element (), a sleeve () and an energy absorbing disc (). The safety belt reel () is provided with a first recess () and a second recess. A first helical surface () is arranged in the first recess (), and the driving element () is provided with a first projection () having a second helical surface acting together with the first helical surface (). The sleeve () is provided with a second projection () mounted in the second recess. Under a predetermined load, the second projection () is cut off, such that the energy absorbing disc () is plastically deformed due to squeezing. The safety belt retractor achieves on the same end segment, the pre-tensioning, force-limiting and decoupling functions as well as a compact structure.
