Image Number 7 for United States Patent #4042957.

This invention relates to a head-up display unit having at least a part so disposed, when in use in a vehicle, as to intercept the line of sight of an observer using the unit to view a scene lying ahead of him. The display unit employs a light deflecting arrangement to enable the observer to see the part of the scene obscured by the unit and includes optical means for projecting light rays from a luminous signal source into the light deflecting arrangement thence to the observer, who sees the luminous signals superimposed on his view of the scene ahead.
