ABSTRACT:
A seat belt automatic unlocking device includes a seat belt having an end portion with a fitting, a lock box structure which receives the seat belt end portion, and a locking lever movably mounted on the lock box structure between a locked position and an unlocked position. The locking lever engages and locks the fitting when in the locked position, the locking lever disengaging and unlocking the fitting when in the unlocked position to thereby unlock the seat belt. A mounting structure is mounted on a vehicle on which the seat belt automatic unlocking device is used, and a connection connects the mounting structure to the lock box structure. A releasable device is operably connected between the mounting structure and the locking lever and operable between a release position and a non-release position, the releasable device being operable to move the locking lever to its unlocked position when the releaseable device is moved to its release position. The releasable device is movable to the released position when the mounting structure and the lock box structure are moved to a separated position, whereby the releasable device automatically unlocks the fitting to thereby unlock the seat belt after application of a separating force exceeding a predetermined biasing force.
