A restraint system includes a retractor housing, a spool rotatably coupled to the retractor housing and defining an axis of rotation, a threaded rod lockable relative to the retractor housing and elongated along the axis, a nut threaded on the threaded rod, and a spring elongated from a first end to a second end. The first end is fixed relative to the spool, and the second end is fixed relative to the nut.

A multi-point seat belt safety apparatus and system and device that automatically moves, adjusts, or otherwise corrects itself around one or more webbing deflection points, and utilizes different components, to accommodate seat occupants with different sizes and ages. In particular, when an occupant extends the webbing across their torso towards an anchor point, generally disposed to the near the side of their waist, the webbing first contacts the torso/shoulder of the occupant at a particular distance above the seat, which is reflective of the occupant's height, causing the webbing to automatically move along a length of a deflection element, positioned at, above, or near the shoulder of the seat occupant, to an appropriate deflection point. At such, the webbing is kept at a proper location, away from the neck of the occupant.

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetic flux interaction that, in effect, may provide a tunable resistance to movement, changing the rate of relative movement between the members. In one embodiment, the device comprises a first member in a kinematic relationship with at least one further member to form a system. The system moves within a limited range of motion and the system interacts when an external energizing force is imposed on the system causing the members to respond due to their kinematic and dynamic characteristics and thereby creating relative motion between the members. The trigger member is coupled to the at least the first member and moves in response to a pre-determined system movement. When the trigger member moves, the trigger member imposes a braking action on the system or a member or members thereof. The speed and/or intensity of the braking action imposed by the trigger member on the system or a member or members thereof is controlled by the trigger member rate of movement. This rate of movement is in turn governed by a magnetic flux interaction between the trigger member and the at least one first member causing formation of a magnetically induced eddy current force between the parts.

A locking web retractor includes a spool mounted between side walls of a frame and rotatable in web take-up and pay out directions, and a locking apparatus including a toothed wheel rotatable with the spool, a movable component and a lock pawl. The movable component moves between a locking position in which it forces an engagement end of the lock pawl into engagement with the toothed wheel to prevent the spool from rotating in the web pay out direction, and an unlocking position in which the movable component does not force the engagement end of the lock pawl toward the toothed wheel. The lock pawl defines a counterweight at an opposite end and configured, in the unlocking position of the movable component, to cause the lock pawl to move in a direction which draws the engagement end of the lock pawl away from the toothed wheel.
