A safety-lock mechanism for use with a multi-position window having a stationary window frame, a sash window frame positioned within the stationary window frame and selectively pivotable out of the stationary window frame about a vertical axis and a horizontal axis, and a drive train positioned between the sash window frame and the stationary window frame, the drive train being moveable between at least a first position which enables the sash window frame to be pivoted about the horizontal axis and a second position which enables the sash window frame to be pivoted about the vertical axis. The safety-lock mechanism includes a spring--biased pin provided on the sash window frame. The pin has a proximal end, a distal end, a locked position and an unlocked position, and is normally biased in the locked position. An aperture is provided within the drive train and is configured to receive the proximal end of the pin. In the locked position, the proximal end of the pin extends into the aperture so as to prevent movement of the drive train from the first position into the second position. When the pin is placed in the unlocked position, the drive train is capable of being moved from the first position into the second position, thereby allowing the sash window frame to be pivoted about the vertical axis.
