Abstract

In a belt retractor (10) having a belt tensioner (16) and a force-limiting device, the belt tensioner (16) includes a pivoted pinion gear (24) associated with a belt reel (14), a drive unit (18) and an oblong force-transmitting element (22) movable by the drive unit (18) supported at least partly in a tubular portion (21) and adapted to be engaged in the pinion gear (24) so as to rotate the pinion gear (24) in a tensioning direction (A). The force-transmitting element (22) includes a bending portion (30) which is provided at the rear end of the force-transmitting element (22) viewed in the tensioning direction and which is designed to be pressure-resistant in the longitudinal direction (L) of the force-transmitting element (22) but to be flexible in a direction perpendicular to the longitudinal direction (L).
