Device for supporting combiner for use in vehicle display system

A supporting device for supporting a combiner for a vehicle display system which is suspended from a ceiling of the vehicle room to be located in front of an eye point in the vehicle room and on which image light of a displayed image for driving information is projected so that a virtual image of the displayed image is visually recognized from the eye point, comprising:

• a first arm with one end pivoted on the ceiling and the other end attached to said combiner, said first arm being swingable around a pivoting point at said one end;
• a second arm with one end pivoted on the ceiling which is apart from the one end of said first arm in a horizontal direction of the vehicle;
• and
• a third arm with one end pivoted on the other end of said second arm and the other end pivoted on the other end of said first arm, wherein
• in a developed state of the combiner where the first arm extends along a vertical line passing the center of gravity of the combiner 13 and said combiner is arranged in front of said eye point, the second arm and the third arm are aligned on and extended along a line which couples a pivoting point at the one end of said second arm on the ceiling and an attaching point at the other end of said first arm to the combiner;
• and
• in a folded state of the combiner where said first arm extends substantially along said ceiling and said combiner is retracted from the front of said eye point toward the ceiling, said second arm is folded relatively to said third arm from a pivoting point of the other end of said second arm on the one end of said third arm so that said second arm and said third arm are extended substantially along the ceiling.
