In display apparatus and method for an automotive vehicle in which an image display is mounted, a road map data image is stored in a storage medium, a mark representing the present position of the vehicle is superimposed on the road map data image, the road map data image is rotated on an image screen of the image display in accordance with a traveling direction of the vehicle while displaying the road map data image on an image screen of the image display, and a display form of the displayed road map data image is varied between a region of the road map data image which is near to a displayed position at which the vehicle is present and another region thereof which is remote from the displayed position thereof while rotating the road map data image on the image screen of the image display section.

Display apparatus and method for automotive vehicle

A display device is provided that does not cause the viewer to experience a feeling that something is abnormal, even when the relative positions of the display device and the viewer fluctuate. The display device basically includes a display section, a motion detecting section, an image displacement computing section and a display control section. The display section displays an image within a display region of a non-head mounted display screen. The motion detecting section detects a movement of the display section. The image displacement computing section computes a translational displacement of the display section based on the movement of the display section. The display control section adjusts a display position of the image within the display region of the display section based at least on the translational displacement of the display section. As a result, the displayed image appears stationary in space to the viewer.

Display device

A display unit is disposed in front of a driver's seat in a front central region of a passenger compartment of a vehicle. A sensor senses a condition, such as a driver's eye position, an outside brightness and a steering frequency, affecting the uneasiness of a driver caused by the display screen. A controller reduces the size of a picture display region in accordance with the condition to achieve an agreeable size and position of picture on the screen.

Display apparatus for vehicle

In display apparatus and method for an automotive vehicle, a display ( ) is disposed on a position of the vehicle placed in a proximity to a dashboard surface of the vehicle and a controller ( ), when a state of the vehicle which satisfies a predetermined condition is detected, executes a process to gradually reduce a brightness of an image screen of the display toward a predetermined direction which is more distant from a direction of a line of sight of a vehicular driver when the vehicular driver gazes a vehicular forward direction. In one embodiment, the controller gradually reduces the brightness of the image screen of the display toward the predetermined direction in a linear manner. The predetermined direction is, for example, directed from an upper end of the image screen to a lower end thereof.

A seat device comprises a cushion frame mounted on a floor; a support member for supporting a seat pad; and torsion bars for elastically supporting the support member on the cushion frame, including a torque bar section and an arm section, wherein the torsion bars are provided at the front and rear positions of the seat or at the left and right positions thereof by at least one pair, and each arm section of the at least one pair of torsion bars be provided so as to form a parallel link mechanism.

Torsion-bar equipped vibration absorbing-seat device

A supporting member in a conventional seat device is supported only by torsion bar arm portions positioned at right and left sides of the device. Accordingly, when a large biased load acts on the device, a sufficient roll rigidity is not obtained and both arm portions at the right and left sides rotate simultaneously. Interference with the supporting panel, cushion frame or the like may also occur. Accordingly, a seat pad supporting member supported by a cushion frame provided on a floor is elastically supported on at least one of the front and rear portions thereof to a torsion frame by a torsion bar. The torsion bar is latched, at the torsion bar torque bar portion side, to the cushion frame side. The torsion arm portion side, moreover, is latched to the right and left sides. Finally, the torsion bar arm portion, on both sides, is connected to a connecting member.
