A switchable retractor system includes a retractor with a spool. The spool is rotatable in an extension direction for extending a web and in a retraction direction for retracting the web. A first clutch has an engaged state where the first clutch inhibits rotation of the spool in the extension direction and a disengaged state where the first clutch allows rotation of the spool in the extension direction. A release actuator actuates the first clutch into the disengaged state when actuated by a user to allow extension of the web. A second clutch has a locked state where the second clutch inhibits rotation of the spool in the retraction direction and an unlocked state where the second clutch allows rotation of the spool in the retraction direction. A tension actuator actuates the second clutch into the unlocked state when actuated to allow retraction of the web into the retractor.

A seatbelt system comprising a buckle; a spool with a ratchet wheel and webbing that is windable onto or off of the spool as the spool rotates. A control mechanism is operatively engaged with a pawl located proximate the ratchet wheel. When the control mechanism is in a first condition, the pawl is disengaged from the ratchet wheel and the ratchet wheel and spool are rotatable to wind the webbing onto or off of the spool. When the control mechanism is in a second condition, the pawl is moved into engagement with the ratchet wheel and the ratchet wheel and spool are only able to rotate the webbing onto the spool. The control mechanism includes electronic switches and sensors that have to be actuated along with engaging the locking tongue in the buckle in order to move the pawl into engagement with the ratchet wheel.

A switchable retractor system includes a retractor with a spool. The spool is rotatable in an extension direction for extending a web and in a retraction direction for retracting the web. A first clutch has an engaged state where the first clutch inhibits rotation of the spool in the extension direction and a disengaged state where the first clutch allows rotation of the spool in the extension direction. A release actuator actuates the first clutch into the disengaged state when actuated by a user to allow extension of the web. A second clutch has a locked state where the second clutch inhibits rotation of the spool in the retraction direction and an unlocked state where the second clutch allows rotation of the spool in the retraction direction. A tension actuator actuates the second clutch into the unlocked state when actuated to allow retraction of the web into the retractor.

Various systems and methods are presented regarding automatically controlling a position of a seat belt located onboard a vehicle, wherein the position is controlled in accordance with physiology of an occupant utilizing the seat belt. By adjusting the position of the seat belt in accordance with the occupant's physiology, the seat belt system can be configured to improve operation of the seat belt in restraining the occupant during vehicle deceleration. Position of the seat belt can be controlled by a guidance device comprising a positionable guide pin which changes alignment of the seatbelt. A motor can be utilized to control positioning of the pin, wherein the motor can be controlled by a system configured to receive data from one or more sensors regarding any of the occupant's physiology, operation of the seat belt, position of the pin, and suchlike.

A seatbelt retractor includes a frame and a spool having a first end and a second end each rotatably supported by the frame. The spool is elongated on an axis from the first end to the second end. The seatbelt retractor includes a plurality of torsion posts fixed to the frame. The seatbelt retractor includes a locking device operatively coupled between the spool and the plurality of torsion posts.

An automatic belt adjustment apparatus includes a fixing buckle, a belt buckle, a belt retractor, and a position switching member. The belt buckle is configured to be buckled with the fixing buckle. The belt retractor is connected to the other end of the belt. The belt retractor includes a locking assembly configured to selectively limit the belt retractor from automatically retracting the belt. The position switching member is movably disposed on at least one of the fixing buckle and the base, and configured to selectively drive the locking assembly to switch between a first position and a second position. When the position switching member drives the locking assembly to switch to the second position, the locking assembly is refrained from limiting the belt retractor from automatically retracting the belt.
