Abstract
A belt tensioner for a belt retractor having a load limiter includes a pivoted pinion () coupled to a belt reel, a drive unit and a load transmission element () moved by the drive unit. The load transmission element () engages in the pinion () so as to rotate the pinion in a tensioning direction A. The load transmission element () is designed so that in the rotational position adopted by the pinion () after being rotated by the load transmission element () a part () of the load transmission element () engages in the pinion (). A method of tensioning a seat belt by means of a belt tensioner and subsequent load limitation by means of a load limiter includes moving a load transmission element () by a drive unit in a first direction so that the load transmission element () engages in a pinion () coupled to a belt reel (). The rotating the pinion () is rotated by the moved load transmission element () in a tensioning direction A. When the rotation of the pinion () is completed it is ensured that a part () of the load transmission element () engages in the pinion ().
