Claims

[Scope of Claim for Utility Model Registration] (1) A head-up display device for a vehicle that projects and displays a display image from a head-up display unit on a reflector provided within the forward field of view of a vehicle driver, wherein said head-up display unit a first drive system that changes and controls the projection angle of a display image from the reflector to the reflector; a second drive system that changes and controls the inclination angle of the reflector; and a seat that is adjusted to suit the physique of the driver. a seat displacement detector that detects the amount of displacement; a viewpoint calculation unit that calculates the driver's viewpoint position based on the detection result; and a viewpoint calculation unit that calculates the optimal display position of the display image corresponding to the viewpoint position, and displays the display image at the optimal display position. a set angle value calculation unit that calculates a display image projection angle value of the head up display unit and an inclination angle value of a reflector necessary for displaying the head up display unit; A head-up display device for a vehicle, comprising: a drive system control section that adjusts the projection angle of the up-display unit and the inclination angle of the reflector. (2) In the vehicle head-up display device according to claim (1), the seat displacement detector includes a seat longitudinal displacement detector, a seatback rotational displacement detector, a headrest vertical displacement detector, and A headrest display device for a vehicle, comprising a headrest rotational displacement detector. (3) In the head-up display device for a vehicle according to claim (1) or (2) of the utility model registration, a head for manually changing the projection angle of the head-up display unit and the inclination angle of the reflector plate. A head-up display for a vehicle, characterized in that it is provided with a switch for arbitrarily varying the display position of the head-up display and an automatic/manual changeover switch so that the display position of the head-up display can be adjusted by both automatic and manual control. Device.
