  • Patent number: 10543764
    Abstract: A vehicle seat (1) includes a seat cushion (2) and a seat back (3), in which the seat cushion (2) is given a stiffness distribution in a front-rear direction in such a way that a front part of the seat cushion is provided with a low stiffness region (PSc) which is more flexible than a rear part of the seat cushion being a high stiffness region (PHc).

  • Patent number: 7815313
    Abstract: A control unit presents a visual stimulus onto a film adhered on an inner surface of a windscreen glass of a vehicle, and controls the visual stimulus so as to allow a driver to perceive the visual stimulus approaching the driver or receding therefrom in response to detection results of a driving environment detection unit, a vehicle status detection unit and a driver status detection unit. In such a way, visually induced vection can be produced for the driver by the visual stimulus. Accordingly, a drive sense of the driver can be adjusted in response to a vehicle state quantity, a driving environment and a driver state.

  • Patent number: 7309096
    Abstract: According to a visibility adjusting apparatus of a vehicle, an apex T is disposed at a position deviated from a driver and between a position opposed to the driver and a vehicle center position, left and right ridgelines uniformly downwardly inclined from the apex T to the vehicle-width direction are set, and a visibility adjusting section is formed as a parting line which adjusts a lower end visibility of the windshield. The visibility adjusting section is formed of the apex and the left and right ridgelines. With this, a sense of balance of the driver can be stabilized by the inclined parting line, and the sway of a head inclination angle can be suppressed.

  • Patent number: 7264386
    Abstract: An illumination property of headlights 4 is controlled so that light quantity or color in a belt-like region B including a virtual line segment A may be different from those in other regions, and thereby the virtual line segment A which uniformly inclines downward from an apex T deviated from a driver toward opposite sides in a vehicle-width direction is indicated on a road surface. The virtual line segment A thus indicated can suppress inclinations of forward visibility and also suppress the sway of ahead inclination angle when a vehicle turns, thereby stabilizing a driving posture of a driver and suppressing steering disturbance.

  • Patent number: 7159924
    Abstract: A visibility adjusting section (10) is formed by making a visible light transmission of a region (A) in a lower side of left and right ridgelines (Rl, Rr) lower than a visible light transmission of a region (B) in an upper side of the left and right ridgelines (Rl, Rr). Accordingly, a driver and a passenger on an assistant driver's seat can see an outer side of a vehicle through the visibility adjusting section (10), and a suitable light can be taken into the vehicle. Further, since a parting line (11) of the visibility adjusting section (10) is uniformly inclined downward toward opposite sides in a vehicle-width direction from an apex (T) disposed at a position which is deviated from a driver, a driving posture of the driver is stabilized, and it is possible to suppress a disturbance in a steering operation.
