An intelligent retractor having a noise removal unit includes: a spool around which webbing is wound; a flywheel which is provided at one side of the spool and rotates along with the rotation of the spool; a locking unit which fixes the flywheel when a predetermined condition for preventing an extension of the webbing is satisfied; and a noise removal unit which rotates along with the rotation of the flywheel when the webbing is retracted, and prevents vibration from being generated in the locking unit.

A retainer apparatus including a first retainer portion, a second retainer portion, a wireless transceiver, and a sensor. The sensor includes a first sensor portion physically contained within the first retainer portion and a second sensor portion physically contained within the second retainer portion. The first retainer portion is removably attached to the second retainer portion. The sensor is configured to detect the first retainer portion being disconnected from the second retainer portion and generate a warning signal. The wireless transceiver is configured to wirelessly transmit the warning signal to a controller in a vehicle to activate an audible warning alert to warn a user in the vehicle of the first retainer portion being disconnected from the second retainer portion.

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 webbing take-up device is provided with a spool and a stopper member. A webbing is taken up onto the spool. The spool includes a webbing insertion hole into which the webbing is inserted. The stopper member secures an end portion of the webbing at the spool by engaging with a periphery portion of the webbing insertion hole. The webbing take-up device is also provided with load bracing portions (a portion at an axial direction one side of a first serrated portion and a portion at an axial direction another side of a rod portion that are formed at a torsion shaft). The load bracing portions are disposed at the diametric direction inner side of the spool relative to the stopper member and are disposed to be close to the spool. The load bracing portions brace a load that is applied to the spool from the webbing via the stopper member.
