Abstract
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.
