A vehicle wiring system includes: an interior member facing a vehicle interior; an additional wiring member disposed on the interior member from a side of the vehicle interior; and an additional interior member. The additional interior member covers the additional wiring member from a side opposite to the interior member.

A vehicle can include a windshield, an A-pillar that is adjacent to the windshield, a hood that is adjacent to the A-pillar and spaced away from the A-pillar by an airflow gap, and an A-pillar garnish. The A-pillar garnish can extend along the windshield and cover at least a portion of the A-pillar. The A-pillar garnish can extend underneath the hood and bend away from the A-pillar and toward the hood. The A-pillar garnish can extend into the airflow gap at a location that is underneath the hood.

An optical member includes a light guide made of a transparent material. The light guide has: an incident surface; an exit surface having exit portions and flat portions; a smooth surface arranged opposite to the flat portions; an upper surface and a lower surface arranged opposite to each other so as to connect the smooth surface and the exit surface; a first protrusion protruding from the upper surface; and a second protrusion protruding from the lower surface. The flat portions reflect the incident light toward the smooth surface by total reflection. The smooth surface reflects the reflected light reflected by the flat portion toward the exit surface by total reflection. The exit portions emit a part of the incident light or a part of light reflected by the smooth surface to the outside.

A windshield for a motor vehicle is described, comprising: a frame with a first rim defining a first opening, and a first window engaging the first opening, supported by the first rim; the frame comprises, in turn, a first and a second cross member opposite one another; and one pair of first pillars opposite one another and extending crosswise to the first and second cross member; the first and second cross member and said pillars delimit said first rim; the frame comprises a second rim and a third rim distinct from one another and arranged on respective opposite sides of the first rim; the frame comprises a pair of third cross members smoothly joined to the first cross member by respective opposite side bands of the first cross member; and a pair of fourth cross members smoothly joined to the second cross member; the second rim is delimited by the first pillar, by a respective third cross member and by a respective fourth cross member; the third rim is delimited by the second pillar, by a respective third cross member and by a fourth cross member.

A vehicle assist handle assembly includes a support structure. A releasable connector is coupled to the support structure. The assist handle support structure has a first end and a second end. The first end has a pivot connector that connects the first end to the support structure and allows the first end to rotate about a pivot axis. The second end is coupled to the releasable connector to connect the second end to the support structure in a use position and is releasable to release the second end. A spring biases the assist handle towards the retracted position. An actuator is configured to release the releasable connector to allow the second end to rotate about the first end to the retracted position.

A center pillar's upper part trim includes a slider and a knob. The slider has a boss projecting in the back side direction. The knob has a flexible member extending in a cantilever manner in a first direction being one operation direction and other end opposed to the flexible member on the first direction side of the flexible member. The center pillar's upper part trim further includes: a slide-and-join structure allowing the knob to slide and join to a plurality of engaging catches from a state where the flexible member of the knob is placed on the boss; and a restriction structure restricting the knob, in a state where the knob has slid and joined, from excessively shifting in the first direction and the second direction by setting the boss between the flexible member and the other end when the knob is operated to slide.
