摘要

#CMT# #/CMT# The device (10) has a reversible electric motor (32) actuating a worm (34) in rotation. A transmission nut (36) integrated to a seat belt fastening system (24) is screwed on the worm and is displaced along the worm when the worm is rotated. A detection unit for looping and detachment of the belt actuates the motor to place the system in a forward position, when the belt is detached, and in an operation position when the belt is looped. Locking units lock and unlock the system when the system reaches the respective positions. #CMT#USE : #/CMT# Used for a seat belt of front and rear seats of a motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The actuation of the reversible electric motor by the detection unit permits to automatically place the seat belt fastening system in a forward position when the belt is detached and in an operation position when the belt is looped, thus permitting to loop the belt in an easy manner while ensuring good efficiency of the belt. The locking units permit to automatically lock and unlock the system when the system reaches the respective positions. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an anchoring device with a seat belt in operation position. 10 : Anchoring device 24 : Seat belt fastening system 32 : Reversible electric motor 34 : Worm 36 : Transmission nut.
