JPS6027687Y2 - automotive sun visor - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sun visor for an automobile, and more particularly to a support device for a sun visor with improved safety.

Traditionally, most automobile sun visors have used an abbreviated metal shaft in order to be able to rotate up and down, left and right, and one side of this shaft is inserted into the sun visor body. The other side is inserted into a bracket attached to the vehicle body panel, which causes the sun visor body to rotate vertically around the shaft, and the shaft itself to rotate left and right around the bracket. .

As a safety measure for this type of sun visor, the main body of the sun visor is covered with a padding material that has a cushioning effect, but since a part of the metal shaft is exposed, it can be used in the event of a collision, sudden braking, etc. Occasionally, the occupant's head would hit the metal shaft, which was extremely dangerous.

To this end, countermeasures have been proposed, such as covering the surface of the shaft with a synthetic resin safety cover to prevent the metal surface from being exposed, but none of these measures have been definitive.

This application was made as a result of intensive research in order to avoid such a dangerous configuration, and uses a synthetic resin shaft instead of the conventional metal shaft, and also uses a synthetic resin shaft in place of the conventional metal shaft. This synthetic resin shaft itself serves as the shaft insertion portion, and attempts to absorb impact by being bent at the notch groove inside the bracket hole.

Hereinafter, one embodiment of the present application will be described based on the drawings. In the figure, reference numeral 1 indicates a sun visor main body. The structure of this sun visor main body 1 is exactly the same as the conventional one, so it is not shown in the drawings. The wire core material is sandwiched between cushioning materials, and then the entire surface is covered with a skin material such as a PVC sheet [7], and a holder having a shaft insertion hole is attached to the wire core material.

One side of the abbreviated synthetic resin shaft 2 is inserted into the holder within the sun visor main body 1.

The other side of the shaft 2 is inserted into a bracket hole 4 of a bracket 3 attached to a vehicle body panel.

By adjusting the frictional force between the holder and the synthetic resin shaft 2, the sun visor body 1 can be adjusted against the shaft 2.
can freely rotate up and down, and due to the frictional force between the inner surface of the bracket hole 4 and the insertion portion 2A of the synthetic resin shaft 2, the synthetic resin shaft 2 is moved against the bracket 3.
can be rotated left and right.

A conventional method may be used to generate this frictional force.

For example, the frictional force between the holder and the shaft 2 can be adjusted by tightening screws to adjust the diameter of the insertion hole of the shaft, and the frictional force between the bracket 3 and the shaft 2 can be adjusted as follows. Bye.

That is, the insertion portion 2A of the synthetic resin shaft 2 is shaped into a tapered shape and forcibly inserted into the bracket hole 4, and the bracket 3 and the tip of the synthetic resin shaft 2 are locked with the bushing nut 5. This creates a frictional force.

Now, the aim of the present invention is to provide the insertion portion 2A of the synthetic resin shaft 2 with an annular cutout groove 6 inside the bracket hole 4 so that in the event of a collision, etc. 2, the synthetic resin shaft 2 self-ruptures around the notched groove 6 to absorb the impact energy.

Appropriate materials include nylon or nylon mixed with glass fiber for the shaft 2, and nylon and polyacetal resin for the bracket 3.

Note that 7 in the figure is a locking pawl provided on the bush nut 5.

As detailed above, according to the present invention, even if the occupant's head hits the sun visor shaft due to a collision, etc.,
The notched groove in the shaft causes the shaft to self-rupture, absorbing the energy of the collision and preventing injury to the occupants.Since the shaft fractured part is located inside the bracket hole, secondary damage caused by the shaft fracture surface is also prevented. It has the effect of being able to.

Claims (1)

[Scope of utility model registration request] For automobiles, a sun visor is configured such that one side of an abbreviated shaft L is inserted into the main body 1, and the other side of the shaft 2 is inserted into a bracket 3 attached to the vehicle body, so that it can rotate freely in the vertical and horizontal directions. In the sun visor for an automobile, the shaft 2 is made of synthetic resin, and a self-rupturing notch 6 is provided in the insertion portion 2A of the shaft 2 and inside the bracket hole 4. Sun visor.
