A seatbelt retractor includes a spool. The seatbelt retractor includes a torsion bar elongated along an axis within the spool and defining passages elongated parallel to the axis, the passages spaced from each other surrounding the axis.

A seatbelt retractor includes a spool elongated along an axis. The seatbelt retractor includes a cylinder supported in the spool and having a thread. The seatbelt retractor includes a torsion bar in the cylinder and having a thread engaged with the thread of the cylinder. The seatbelt retractor includes a stopper supported by the torsion bar at the thread of the torsion bar and spaced from the cylinder.

A seat belt safety apparatus for a vehicle is provided and implements both of the functions of a retractor and a pretensioner in a structure with a seat belt disposed in a seat. The functions of a retractor and a pretensioner are separated in the seat belt safety apparatus to reduce the installation space.

The invention relates to an active restraint system (1), comprising a seat belt retractor (3), having a frame (2) and a belt reel (4) with a belt webbing (10) wound thereon and rotatable supported by the frame (2) for allowing winding and unwinding the belt webbing (10). An electric disc motor (28) comprising a rotor (30) and a stator (32) is attached to the belt reel (4). The rotor (30) is directly attached by an attachment (31) to the belt reel (4). The restraint system further comprises a control unit (40) connected to the disc motor (28) and adapted to control the disc motor (28) to drive the belt reel (4) in accordance with a determined belt motion profile.

A three-point installation bracket for converting a two-point seat belt system included factory in a convertible vehicle to a three-point seat belt system without requiring modifications/changes to the existing vehicle frame. The disclosure also includes methods for installing the bracket, as well as kits including same.
