Definitions

• This invention relates to a vehicle sun visor assembly having moveable coverage.
• Visors typically are mounted to a vehicle by an elbow mounting bracket which couples one end of a visor pivot rod to the vehicle. Visors include a visor body, with the other end of the visor pivot rod extending into the visor body. A torque fitting extends between the visor body and the visor pivot rod to allow the visor to rotate on the visor pivot rod from a stored position adjacent the vehicle headliner to various adjusted lowered on use positions.
• the elbow bracket allows the visor to be pivoted to a side window position for blocking incoming sunlight from the side of the vehicle.
• a visor of this type can block glare coming through the driver's side window and a small portion of the front window, but not from all directions in the driver's vision.
• SOR visors that slide along the pivot rod, called slide-on-rod (“SOR”) visors.
• Current SOR visors use a closed, D-shaped channel or 2-piece channels into which the visor pivot rod, a carrier (e.g., a plastic guide), and detent spring are inserted and along which the visor pivot rod slides.
• the D- shaped channel is manufactured as an extruded aluminum component, an expensive process.
• the "D" shape of the channel, and stiff wall section makes it difficult to obtain optimal resistance to movement, which is either too high or too low due to the tolerances required.
• a loose fit of the channel over the carrier leads to undesirable noise from vehicle-induced vibrations in the visor. The loose fit can also fail to provide sufficient resistance to movements, and thus fail to hold the visor in place.
• This invention relates to a vehicle visor, comprising a visor pivot rod, a carrier on the visor pivot rod, a spring mechanism inside the carrier, and an open channel with a first end and a second end, wherein at least a portion of the carrier extends into the interior
• the vehicle visor comprises a channel and the carrier slides along the channel.
• the spring mechanism comprises a detent spring assembly, which provides a compressive force on the pivot rod.
• the detent spring rotates or pivots relative to pivot rod.
• the carrier flexes the inside of the channel.
• wires pass through the hollow rod and exit through the side of the open channel, reducing the amount of wire required.
• end stops for the SOR-movement of the carrier are provided, more preferably inside the channel. Even more preferably, the end- stops are the end caps, which are most preferably, rigidly connected to the channel.
• the surface of the end caps provide a datum surface for the movement of the carrier.
• the vehicle visor comprises a visor core, which has two parts, which are connected, preferably sealed together.
• the pivot rod, the channel, wire and/or the end cap are held in place by the visor core after the parts have been connected.
• the carrier has a slot that fits over the hemmed or rounded edge of the channel.

• the detent spring assembly 130 provides compressive force on the pivot rod 110.
• the detent spring assembly 130 rotates or pivots relative to the pivot rod 110, permitting the visor 100 to be moved between the stowed and the in use positions.

In some exemplary embodiments, the channel 150 is not fully enclosed around its circumference, although the open portion may be very small. In various exemplary embodiments, the carrier 140 has an external shape that is similar to, but not necessarily identical to, the interior shape of the channel 150. The pieces are generally shaped such that they fit together, allowing the carrier 140 to slide along the length of the channel 150 without permitting appreciable movement in any other directions. [0052] As shown in Fig. 14, in various exemplary embodiments, the channel 150 is not fully enclosed. This channel 150 has a basic C-shaped profile. This embodiment also has a channel cross section with angled surfaces.
• the angled corners on the top allow the channel to fit into the top of the visor's rounded shape.
• the lower angled surfaces reduce side movement of the carrier during rotation. These angled surfaces can be rounded and provide the same function.

• Other examples of closed cross sections can created by extruding, welding, riveting, adhesive, or other similar processes of joining materials.
• visors include illuminated vanity mirrors and/or powered accessories, such as garage door opener transmitters, memo recorders, or other electrical accessories. Power to such accessories is typically provided via one or more wires that run into the vanity inside the visor pivot rod and channel. This requires a sufficient length of wires to reach the end of the channel and back to the one or more electrical accessories when the visor is fully extended, which is a significantly longer distance than a direct route.
• the selected shapes for the carrier 140 and the channel 150 are such that the selected shapes facilitate passage of one or more wire 160 between the interior of the carrier 140 and the visor 100.
• the wire(s) 160 need not be long enough to extend the length of the pivot rod 110 plus the channel 150 (as when the visor is slid out to its full capacity). Instead, the wire(s) 160, which typically runs into the visor 100 through the interior of the pivot rod 110, may exit the pivot rod 110 at any preselected point either within the carrier 140 or at the end of the pivot rod 110 and pass through the opening in the channel 150 to the visor 100 core.
• the wire(s) 160 exits the visor pivot rod 110.
• the wire(s) 160 can be designed so that it is not affected by the movement of the visor 100 relative to the pivot rod 110 (or, in other words, by the movement of the carrier 140 relative to the channel 150).

• the carrier may be preloaded in the channel to allow for larger tolerances and still have a tight fit.
• the channel opening "grips" the carrier and provides slide resistance as well as noise reduction throughout rotation and slide movement.
• the channel has angled surfaces that restrict carrier movement in the channel and act as a damper when motion does occur. Angled surfaces may be applied to any channel design, whether open or closed, or manufacturing processes, such as, for example, extruded, roll-formed, or stamped.
• references to relative positions are merely used to identify various elements as are oriented in the figures. It should be recognized that the orientation of particular components may vary greatly depending on the application in which they are used.
• the terms “coupled” and/or “attached” means the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or moveable in nature.

• Fig. 33 shows the carrier 140 inside the channel 150.
• the edges of the channel are deflected in order to avoid sharp edges.
• One of the deflected edges is inserted into a groove, in the carrier. This optimizes the guidance of the carrier during its movement in the channel.
• the channel is slightly smaller than the carrier, so that the channel is, in defined regions, which are identified by arrows, pressed against the carrier.
• Fig. 34 depicts the visor core, which is made of two parts 101.1 and 101.2, which are sealed together. Both parts comprise rips 200, which are, preferably arranged perpendicular to the channel and which fix the channel inside the core. As can also be seen from figure 34, in the end region of the channel, end caps are inserted into the channel. The wedges 300 of the end caps open the channel ends.
