摘要： 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).

摘要： A belt retractor includes a retractor frame (10) having first and second end faces (10a, 10b) between which a belt reel (12) is pivoted. The belt retractor further includes a belt tensioner and a spring cassette (30) having a helical spring (26) coupled to the belt reel (12). The spring cassette (30) is arranged between the first end face (10a) of the retractor frame (10) and at least one component of the belt tensioner. A method of fitting such belt retractor includes mounting the spring cassette (30) on a component of the belt tensioner, especially on an inside of a tensioner casing (22) and mounting the belt tensioner including the spring cassette (30) on the retractor frame (10), especially on an end wall (10a) of the retractor frame (10). An alternative fitting method includes mounting the spring cassette (30) on an end wall (10a) of the retractor frame (10) and attaching the belt tensioner to the spring cassette (30) mounted on the end wall (10a) of the retractor frame (10).

摘要： A belt tensioner for a belt retractor having a load limiter includes a pivoted pinion (14) coupled to a belt reel, a drive unit and a load transmission element (20) moved by the drive unit. The load transmission element (20) engages in the pinion (14) so as to rotate the pinion in a tensioning direction A. The load transmission element (20) is designed so that in the rotational position adopted by the pinion (14) after being rotated by the load transmission element (20) a part (20b) of the load transmission element (20) engages in the pinion (14). 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 (20) by a drive unit in a first direction so that the load transmission element (20) engages in a pinion (14) coupled to a belt reel (12). The rotating the pinion (14) is rotated by the moved load transmission element (20) in a tensioning direction A. When the rotation of the pinion (14) is completed it is ensured that a part (20b) of the load transmission element (20) engages in the pinion (14).

摘要： A drive wheel (14) for a belt tensioner is adapted to be coupled to a belt reel and includes an external tooth system including plural teeth (30) distributed along the circumference. The teeth (30) are inclined in a first circumferential direction B and/or the teeth (30) have at least one end face (36) facing away from the central axis A of the drive wheel (14) and being inclined in a first circumferential direction B and/or the clearances (42) between neighboring teeth (30) are not symmetrical with respect to planes defined by radial and axial directions. Moreover, the teeth (30) have no symmetry with respect to planes E extending tangentially relative to the circumferential direction. A belt tensioner for a seatbelt system includes a force transmission element (20) and means for driving the force transmission element (20). The belt tensioner further includes a pivoted drive wheel (14) of the afore-described kind having an external tooth system on which the force transmission element (20) acts upon activation of the drive means so as to rotate the drive wheel (14).
