Safety belt reeling device and safety belt tightening device combination with power limiter

A self-locking safety-belt reeling device comprising:

• a reeling shaft on which a safety-belt is wound;
• a blocking device controlled by at least one of a vehicle-sensitive control mechanism and a safety-belt-sensitive control mechanism for blocking said reeling shaft;
• a tightening device directly acting on said reeling shaft, said tightening device comprising a tightener coupling;
• said tightening device further comprising a drive disk, said drive disk, upon activation of said tightening device, driven in rotation by a drive device and coupled with said tightener coupling directly to said reeling shaft;
• a power limiter for allowing a limited removal of the safety belt in order to dissipate energy after activation of said tightening device and completion of the tightening movement;
• a coupling device between said power limiter and said reeling shaft for activating and deactivating said power limiter, wherein in an operational state of normal blocking with said blocking device without activation of said tightening device said power limiter is deactivated, in an operational state of activation of said lightening device and completion of the tightening movement said power limiter is activated, and, after completion of said tightening process and loading of said power limiter, said power limiter is deactivated.
