ABSTRACT:
An emergency unlock assembly is provided for unlocking a lock mechanism associated with an onboard opening cover such as a boarding door, in response to the detection of an impact applied. The assembly includes means for detecting the presence or absence of an occupant within a vehicle. When the presence of an occupant is detected, the lock mechanism is unlocked in response to the detection of an impact applied. The lock mechanism is not unlocked in response to the detection of an impact applied in the absence of an occupant. This allows a rapid rescue of an inboard occupant in the event of an emergency while reliably preventing a casuality such as a theft of or articles placed in a vehicle in the absence of an occupant.
