Japanese Patent No. 4003497

However, it is not easy to pass the wire harness extending from the ECU through the through hole of the ceiling base material. It is also not easy to assemble the panel to the ceiling substrate so as to hide the wire harnesses electrically connected to the electrical components. Moreover, when the sun visor is attached to the ceiling base material, it may be necessary to electrically connect the electrical parts in the sun visor to the wire harness. Therefore, there is a conventional need for a sun visor unit that can be easily assembled to the ceiling of the vehicle.

According to one feature of the present disclosure, a vehicle sun visor unit has a plate-like visor body. A support shaft is provided along the upper end of the visor body for vertically rotatably supporting the visor body. The end of the spindle is attached to a plate-like garnish. A wire harness is routed on the top surface of the garnish. Electrical components are connected to the wire harness and provided on the garnish, or/and electrical components are connected to current-carrying members passing through the spindle and provided on the visor body. A garnish is attached to the vehicle ceiling so as to cover the underside of the headlining. Left and right ends of the garnish are covered from below by a center console provided on the ceiling of the vehicle. An end of the wire harness is connected to a power line routed to the ceiling of the vehicle above the center console.

The visor body and the garnish can thus be assembled together before being mounted on the vehicle ceiling. Moreover, the wire harness routed on the upper surface of the garnish and the electric parts provided on the garnish and/or the visor body can be electrically connected. The garnish is attached to the ceiling of the vehicle as a unit. The ends of the wire harness can then be connected to power wires extending from the vehicle ceiling. The wire harness ends and power lines are covered by the center console, which will be installed later. Power wires are therefore exposed to the vehicle luggage compartment without passing through the small through hole in the headlining. The wiring harness ends and power lines are covered from below by the center console. Therefore, the sun visor unit can be easily attached to the ceiling of the vehicle with good appearance.

According to another feature, a support shaft extending along an extension line of the support shaft is provided on the side opposite to the end of the support shaft of the visor body. The garnish has a hook on which the support shaft is detachably hooked. The hook is thus attached to the vehicle ceiling together with the visor body and the garnish. Therefore, the hook can be easily and accurately positioned with respect to the support shaft of the visor body.

According to another feature, the upper surface of the garnish is provided with lighting fixtures electrically connected to the wiring harness. The luminaires are oriented to emit light towards the occupants through windows in the garnish. Therefore, it is possible to appropriately illuminate the occupant while providing the lighting device on the upper surface of the garnish with good appearance.
