Description

[Detailed explanation of the idea] The present invention relates to the improvement of sun visors for vehicles.

The support shaft of a conventional sun visor has a cross-sectional size perpendicular to the axial direction that is approximately the same size as the axial direction, and has strong rigidity.If an occupant collides with the support shaft of the sun visor or the vicinity of the support shaft, There was a problem in that it caused damage to passengers because it was difficult to deform plastically.

On the other hand, if the overall size of the cross section perpendicular to the axial direction of the support shaft is made smaller, the rigidity of the support shaft will become weaker, and the sun visor may vibrate while the vehicle is running or when the sun visor is rotated, the support shaft may flex, causing rotation of the sun visor. There was a problem with the feeling being bad.

In the case of Metajitsu Publication No. 51-93519, an annular groove is provided on the outer periphery of the rotating shaft so that the rotating shaft does not come out from the bracket that attaches the sun visor to the vehicle body. There was a problem that it could not be transformed.

Furthermore, the sun visor disclosed in Japanese Utility Model Application Publication No. 54-36226 also has the problem that if an occupant collides with the mounting shaft, the mounting shaft cannot be effectively plastically deformed, causing damage to the occupant.

This invention was devised to address the above-mentioned problem, and has a support shaft that is attached to the interior plate of the vehicle via a bracket at one end and rotatably supports a support member installed inside the sun visor at the other end. and between the bracket and the support member,
The object of the present invention is to provide a sun visor for a vehicle, characterized in that the support shaft that can be pressed has a weak point.

According to the present invention, only a weak point, such as a groove in the circumferential direction, is provided between the bracket and the support member in the conventional support shaft. Since the rigidity hardly weakens, there is no problem such as the sun visor vibrating while the vehicle is running or the support shaft bending when rotating the sun visor, resulting in a poor rotational feeling of the sun visor. In the event of a collision in the vicinity, the support shaft is plastically deformed in the groove provided in the support shaft and absorbs a portion of the collision energy, resulting in the effect that damage to the occupant can be reduced compared to conventional damage.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 in the figure has a bent part, one end is a tapered part whose outer diameter decreases toward the tip, and the other end is tapered from the bent part to form a dogleg shape with a groove 1a provided in the circumferential direction. 2 is a support shaft arranged inside a soft material 6 made of a vinyl chloride film and a pad, and has a frame line that has approximately the same shape as the outer edge of the soft material and holds the soft material; 3 is a frame The shaft fixed to line 2, the coaxial axis line is arranged in a straight line with the axis line on the other end side of the support shaft 1, 4 fixes both ends of the frame line 20, and further axis the other end side of the support shaft 1. The supporting member γ is a bracket.

The bracket is drilled in itself, and the tapered part on one end of the support shaft 1 is inserted into a tapered hole whose inner diameter decreases from one end to the other. A spring 9 is interposed between a stopper 10 fixed to the tip of one end of the support shaft 1 protruding outside the bracket and a washer 8 disposed at the other end of the tapered hole of the bracket. The spring always biases the support shaft 1 so that it does not come off the bracket.

The sun visor having the above configuration is attached by fixing the bracket 7 to the inner plate at the upper end of the front windshield of a vehicle (not shown) with screws, etc., and the shaft 3 is pivotally supported by a support fixed to the inner plate of the vehicle (not shown). Ru.

However, the shaft 3 can be easily inserted into and removed from the support without using any tools, and the sun visor can also be used while being supported only by the support shaft 1.

When the sun visor is installed, a bending moment acts on the support shaft 1, but since the circumferential direction 41a provided on the support shaft 1 is the bent side end of the support plate 4, the bending moment does not act on the groove. Since the bending moment is small and the rigidity of the support shaft 1 is hardly weakened even if the groove 1a is provided, vibrations of the sun visor,
If the occupant collides with the support shaft 1 of the sun visor or the vicinity of the support shaft 1, deterioration of the rotational feeling is not a problem, and the support shaft 1 is plastically deformed in the groove 1a and absorbs part of the collision energy. The damage caused to passengers can be reduced compared to conventional ones.

Note that since the groove 1a is provided inside the outer edge of the soft material 6, the appearance is the same as the conventional one.

As another embodiment of the present invention, as shown in FIG. 3, a weak point such as a notch in the circumferential direction is provided in a part of the support shaft 1, and substantially the same effect as in the above embodiment can be obtained.
