Description

[Detailed Description of the Invention] This invention relates to a sun visor installed in a vehicle interior.

When direct incident light such as sunlight enters the driver's eyes while the vehicle is running, the driver's field of vision is obstructed, impeding safety while driving. To prevent this, conventionally,
A sun visor is used. This sun visor has a light shielding plate disposed at a position that blocks incident light from entering the driver's eyes, and when not in use, the light shielding plate can be stored in a bonded state to the inner wall of the ceiling of the vehicle. For example, a sun visor 1 as shown in FIG. 1 consists of a light shielding plate 2 and an arm 3 to which this is pivotally attached, and an upright portion 301 of this arm is pivotally attached to the upper part of the interior wall of the vehicle via a mounting bracket 4. . When arm 3 faces the front window, sunlight from the front of the vehicle can be
When facing the side window, each side blocks sunlight. However, in the sun visor 1, the light shielding plate 2 only rotates around the upright portion 301 of the arm, and the range of shielding sunlight etc. is limited. For this reason, conventional sun visors have the disadvantage of not being able to cope with wide-ranging changes in the direction and angle of incidence of directly incident light, which constantly change when the vehicle is running.

The purpose of this invention is to provide a sun visor that can secure a sufficiently large light-shielding area compared to the size of the light-shielding plate.

The sun visor according to this invention is installed near the corner of the upper edge of the front window and the upper edge of the side window adjacent to the front window, and the sun visor is set from the corner of the upper edge of the side window. a rotary member that is supported only rotatably around an axis substantially along the vehicle width direction at a portion separated by a distance; and an L-shaped stay that has one arm rotatably supported by the rotary member. , a light-shielding plate supported on the other arm of the stay so as to be rotatable about its axis; It is supported by the rotating member so that it can only rotate about an axis passing near the upper edge of the side window, and the one arm is attached above the side window on the front side of the vehicle body of the rotating member. The length of the other arm is such that the other arm is positioned along the upper edge of the front window when the other arm is positioned along the edge, and each rotating portion of the rotating member and the stay has a predetermined value. It is characterized in that friction is applied by the elastic force of each spring so that it rotates when the above rotational force is applied.

According to such a sun visor, it is easy to switch the unused light shielding plate to the use position, which is the position covering the upper part of the front window, and it is possible to secure a wide light shielding area. When the light shielding plate is placed close to the front pillar as the vertical frame of the front window, it is also possible to prevent ghosts caused by the side window glass.

Furthermore, the frictional force generated by the spring can be stably applied as a rotation regulating force around each rotation axis, and the stay can be rotated easily around the rotation axis.

This invention will be explained below with reference to the accompanying drawings.

FIG. 2 shows a vehicle 6 equipped with a sun visor 5 as an embodiment of this invention. This vehicle 6 includes a front window 7, a front pillar 8 as a pair of left and right vertical frames (the left side is not shown), a windshield header panel (hereinafter simply referred to as a roof header) 9, and an instrument panel (not shown). A windshield 10 is attached here to prevent outside air from entering the vehicle interior 11. A door 12 is provided on the side of the vehicle,
A side window 13 is formed at the top of this door 12. A side glass 14 is attached to this side window, and the side glass is opened and closed by being moved up and down by a window regulator (not shown). The door 12 has its front portion facing the front pillar 8, its upper portion facing a roof side rail (hereinafter simply referred to as side rail) 15, its rear portion facing a rear pillar (not shown), and its lower portion facing a side sill (not shown) so as to be able to come into contact with and separate from the door 12. . Note that both the roof header 9 and the side rails 15 are attached to the roof 1.
6 and secures the rigidity of the upper part of the passenger compartment.

The sun visor 5 has a mounting bracket 17 screwed to the vertical wall surface 151 which is the upper edge of the side rail 15.
It is attached to the vehicle body side via. This mounting bracket 17
is disposed a distance L1 rearward from the corner facing the upper end of the front pillar 8, that is, the front end in the vehicle longitudinal direction As shown in FIG. 3, the rotating member 18 has its shaft portion 181 fitted into the mounting fitting 17. As shown in FIG. In addition, a first spring 19 is fitted into a portion protruding from the back side of the mounting fitting 17, and this first spring is supported by a stopper 20 so as not to be detachable.
This shaft portion 181, first spring 19, and stopper 20 form a rotation regulating portion. For this reason, the rotating member 1
8 is rotatable around a first rotation center line (hereinafter simply referred to as the first center line) l1 that faces approximately in the vehicle width direction Y;
Further, due to the frictional force based on the elastic force of the first spring 19, rotation around the first center line l1 is prevented by a force below a predetermined value. This rotating member 18 has a bearing portion 182 formed at its tip end, and this bearing portion has a second rotation center line (hereinafter simply a second rotation center line) orthogonal to the first center line l1.
A hole 183 is formed in the direction of 12 (denoted as center line). A mounting shaft portion 211 of an arm 21 made of an L-shaped steel rod serving as a stay is fitted into the hole 183. Of this mounting shaft portion 211, the bearing portion 18
A second spring 22 that applies a frictional force based on elastic force is fitted into the protruding portion from 2, and this second spring is supported by a stopper 23 so as not to be detachable. The mounting shaft portion 211, the second spring 22, and the stopper 23 form a rotation regulating portion. Further, the arm 21 has an elongated portion 212 extending from the mounting shaft portion 211 and extending in a radial direction from the first center line l1, that is, in a direction approximate to the second center line l2, and a first elongated portion of the elongated portion 212.
It is formed by a pivoting portion (hereinafter simply referred to as a pivoting portion) 214 of a light shielding plate 24, which will be described later, and is bent into an L shape at a rotation end 213 farthest from the center line l1. In this way, the rotating member 18 can only rotate relative to the mounting bracket 17, and the arm 21 can only rotate relative to the rotating member 17.
The arms 21 are attached so that they can only rotate relative to each other, and the arm 21 makes a first rotation A by receiving a force above a certain level around the first center line l1, and also rotates around the second center line l2. The second rotation B can be performed by receiving a force through the pivot portion 214. A light shielding plate 24 is attached to the pivot portion 214 of the arm. This light shielding plate 24 is attached to the pivot portion 214 via a tightly fitted hinge (not shown), and rotates a third time C when a force of a certain amount or more is applied around the pivot portion 214 . The light shielding plate 24 is made by wrapping a core material (not shown) in a soft pad and covering it with a skin, and is formed to have a length approximately equal to the pivot portion 214 and a width approximately equal to the length of the elongated portion 212. . In this case, the length of the elongated portion 212 is the distance L1 between the mounting bracket 17 and the upper end position of the front pillar 8.
It is set to be slightly shorter. Furthermore, when the long part 212 of the arm is rotated around the first center line l1 and the rotating end 213 is made to face the upper end position of the front pillar 8, that is, the long part 212 is arranged in the vehicle longitudinal direction X. In this case, in this state, the second center line l2
When the pivot portion 214 is rotated around the front pillar 8 so as to face downward from the upper end of the front pillar 8, the pivot portion 214 is parallel to and close to the front pillar 8 (position g in FIG. 4). The degree of bending of the arm 21 is set so as to

The operation of the sun visor 5 shown in FIG. 2 will be explained.

First, when the sun visor 5 is not in use as shown in position a in FIGS. 2 and 4, the sun visor 5 is
4 is housed so as to be joined to the roof header 9 side. At this time, the arm 21 is held with its straight portion 212 close to the side rail 15, the rotating portion 213 close to the upper end of the front pillar 8, and the pivot portion 214 close to the roof header 9. The light shielding plate 24 at the a position is attached to the third
When it is rotated C, it reaches position b in FIG. 4, and the area b in FIG. 5 can be shielded from light. Next, the arm 21 is rotated a first time A, and the light shielding plate 24 is rotated a third time C.
Then, the light shielding plate 24 reaches position C in FIG. 4 and blocks light in area C in FIG. 5. Next, arm 2
1, rotate the arm in the first rotation A, direct the second center line l2 in the vertical direction, and then rotate the arm in the second rotation B.
Then, the light shielding plate reaches the d position in Fig. 4 and reaches the 6th position.
The area d in the figure is shielded from light. Next, when the light shielding plate at position d is rotated a third time C, it reaches position e in FIG. 4 and blocks light in area e in FIG. 6. Subsequently, when the arm 21 is rotated A first from position e, the light shielding plate 24
reaches the f position in FIG. 4 and blocks the f region in FIG. 6 from light. Further, the light shielding plate at position f reaches position g in FIG. 4 when it is slightly rotated a third time C, and acts as a ghost visor as shown in FIG. 7. Next, g
When the light-shielding plate at the position is rotated a large third rotation C, it reaches the h-position in FIG. 4 and blocks light in the h-area in FIG. 5. Here, it is assumed that the light shielding plate 24 is set again at the a position, and then when it is rotated for the first time A, the light shielding plate reaches the i position on the center side of the roof 16. When the light shielding plate 24 at the i position is rotated a second time B, it reaches the j position in FIG. 4, and it reaches the j position in FIG.
Block the area from light. Furthermore, the light shielding plate at the j position reaches the k position in FIG. 4 by rotating it a third time c, thereby shielding the k area in FIG. 6 from light. In addition, the light shielding plate 2
4 is at the g position, this light shielding plate is located within the blind spot α1 of the front pillar 8 with respect to the driver's field of vision. Therefore, the light shielding plate 24 itself does not narrow the driver's field of view. Moreover, when the illuminance outside the vehicle is lower than that inside the vehicle (for example, at night), the illumination light from the meters M is reflected on the side glass 14, which allows the outside image of the vehicle from the side mirror 25 for visually viewing the rear view to be viewed. It can prevent so-called ghosts that cannot be done.

In the sun visor 5 shown in FIG. 2, the arm 21 can make first and second rotations A and B, and in addition, the light shielding plate 24 can make a third rotation C. Therefore, b, c, h
A light shielding area consisting of areas can be set on the front window side, and a light shielding area consisting of areas d, e, f, j, and k can be set on the side window 13 side. In particular, when switching to the frequently used region b, simply move the light shielding plate 2 from the non-use position.
4 around the pivot joint 214,
Good operability. Furthermore, the positions of the light shielding plates forming these light shielding areas can be easily moved according to changes in the direction and angle of incidence of sunlight. Therefore, even if the light shielding plate 24 is made relatively small, a sufficiently wide light shielding area (approximately 2.5 times the width of the light shielding plate) can be secured by the action of the arm 21.

Furthermore, the first and second rotation center lines l and l are almost perpendicular to each other, and when rotating the stay around either rotation axis, the rotation operation is always performed around this orthogonal part, A smooth rotation operation can be performed with one hand without causing problems such as the occupant misunderstanding the center of rotation and applying excessive force to bend the stay. Also, the second rotation center line l
Since the rotating member passes near the upper edge of the side window, the amount of protrusion of the rotating member into the vehicle interior can be extremely reduced, which is useful for safety.

In the sun visor 5 shown in FIG. 2, the rotating member 18 is attached to the side rail 15 via the mounting bracket 17, but instead of this, as shown in FIG. The sun visor 27 may be constructed by attaching it to the side end portion of the roof 16, which is the upper edge of the side window, via a mounting bracket 27 that pivots thereon. In this case, the shaft portion 261 of the drooping moving shaft 26 is attached to the mounting bracket 27 in a non-removable manner and rotatable around the vertical center line 10. Furthermore, this drooping movement shaft 26 is subjected to rotational resistance due to the action of a spring (not shown), and rotates only when it receives a force of a predetermined value or more. A bearing portion 26 is provided at the lower end of the drooping moving shaft 26.
2 is formed, and at its center is a rotating member 1 that rotates around a first center line l1 perpendicular to the vertical center line l0.
8, which is mounted in the same manner as described in FIG.

The sun visor 27 shown in FIG. 8 performs the first, second, and third rotations A, B, and C in the same way as the sun visor 5 shown in FIG. This has the advantage that the light shielding area can be further expanded.
