A vehicle seat () includes a seat cushion () and a seat back (), in which the seat cushion () 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).

Vehicle seat and stiffness setting method for vehicle seat

A vehicle interior device includes a first illumination unit configured to illuminate a first region of a passenger compartment of a vehicle, a second illumination unit configured to illuminate a second region in a rear part of the vehicle more rearward than the first region and being disposed in the upper part of the passenger compartment, a third illumination unit configured to illuminate a third region in a low part of the vehicle lower than the first region and being disposed in the front part of the passenger compartment, a fourth illumination unit configured to illuminate a fourth region in the rear part and in the low part, and a controller programmed to differentiate at least one of an intensity of the first illumination unit relative to the fourth illumination unit and an intensity of the second illumination unit relative to the third illumination intensity unit.

Vehicle interior illumination device

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.

Drive sense adjusting apparatus and drive sense adjusting method

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.

Visibility adjusting method and apparatus of vehicle

An illumination property of headlightsis 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.

Method and apparatus for adjusting visibility of vehicle

A visibility adjusting section () 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 (), and a suitable light can be taken into the vehicle. Further, since a parting line () of the visibility adjusting section () 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.
