As a result of the headrest being in the "up" position, a child seated in the ics would receive less than the intended protection in the child head area in the event of a crash.
Vehicle description: Minivan equipped with second row bench seats with optional integrated child seat (ics). The headrest lockout mechanism on the seats may not engage and lock the headrests in the "down" position, as intended, when the ics is deployed. A vehicle occupant could move the headrest to the "up" position.
