Abstract

PROBLEM TO BE SOLVED: To provide a vehicular sun roof deflector capable of reconciling the decrease of sliding resistance of a sliding panel and the increase of up position holding force of a blade in higher dimensions. SOLUTION: A vehicular sun roof deflector 1 having a blade 9 and a blade supporting arm 4 springily energized in a direction of lifting the blade 9 is provided with a link 8 with one end engaged with an oblong hole 6 provided on the roof inner frame 2 side and with the other end connected to the blade 9 so as to rise with the ascent of the blade 9, and a spring means 11 energizing one end of the link 8 in the rising direction. Holding of the blade 9 in the up position can therefore be assigned to the spring means 11 for energizing the link 8 in the rising direction, so that energizing force to the arm 4 has only the force enough to lift the blade 9.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof deflector for a vehicle.

[0002]

2. Description of the Related Art In a sunroof having an openable and closable opening in a fixed roof of an automobile, in order to suppress a wind noise generated when the vehicle is running with the opening being opened and wind engulfment into a vehicle interior, It is known to provide a deflector along the front edge of the opening at the time of opening (Japanese Utility Model Laid-Open No. 3-522).
No. 29).

Conventionally, the above-mentioned deflector supports the blade at the other end of an arm pivotally attached to the roof inner frame at one end, and elastically urges the arm with a leaf spring or the like to apply force to the blade. A blade is retracted below the slide panel by applying an ascending force and pressing down the arm with a shoe provided on the lower surface of the slide panel when closing the slide panel.

[0004]

However, in order to prevent the blade from vibrating at the raised position by wind pressure, it is necessary to increase the spring force applied to the arm to some extent. However, on the other hand, the blade is lowered by pushing down the arm with the sliding panel that closes, so that the greater the spring force, the greater the sliding resistance in the closing direction. Also, the reaction force of the spring for urging the arm increases as the blade descends and decreases as the blade ascends. Therefore, it has been impossible to achieve a reduction in the sliding resistance of the slide panel and an increase in the blade position holding force.

On the other hand, the dimension of the arm for supporting the blade is preferably as short as possible from the viewpoint of making the apparatus compact. If the blade is merely raised, a leaf spring having a simple structure and easy to assemble is preferable as the urging means for the arm. However, shortening the arm means that the leaf spring must also be shortened. When the leaf spring is made short, the rate of change of the reaction force with respect to the bending becomes large, so that it is even more difficult to achieve both a reduction in the sliding resistance of the slide panel and an increase in the blade position holding force.

The present invention has been devised to solve such problems of the prior art, and its object is to further reduce the sliding resistance of the slide panel and increase the holding force of the blade in the raised position. It is an object of the present invention to provide a sunroof deflector for a vehicle configured to be compatible with a high dimension.

[0007]

In order to achieve such an object, the present invention provides a vehicle sunroof having a blade 9 and a blade support arm 4 which is resiliently biased in a direction for raising the blade. In the deflector 1, one end thereof is engaged with the elongated hole 6 provided on the roof inner frame 2 side, and the other end is connected to the blade, and the link 8 rises as the blade rises, and the direction in which the link rises. Spring means 11 for urging one end of the link. According to this, the holding of the blade in the raised position can be performed by the spring means for urging the link in the upright direction, so that the urging force on the arm is merely a force sufficient to raise the blade. . Further, if the spring means is a torsion coil spring and the coil portion is arranged on the lower surface of the roof inner frame, the dimensions of the sunroof device are not affected, and the appearance is not impaired.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to specific embodiments shown in the accompanying drawings.

FIG. 1 shows a deflector of a vehicle sunroof constructed according to the present invention. The deflector 1 includes a pair of arms 4 whose rear ends are tiltably supported by a rear base 3 fixed to left and right sides of a roof inner frame 2 provided inside a fixed roof, and a roof inner frame 2. A link 8 having one end engaged with a pin 7 in a longitudinal direction hole 6 formed in a front base 5 fixed to the front of the rear base 3 on both left and right sides of the rear base 3; And a blade 9 connected to the other end of the blade. Thus, an unequal-length four-bar link supporting the blade 9 so as to be able to move up and down with respect to the roof inner frame 2 is formed.

The arm 4 is always resiliently urged upward (ie, upward) by a leaf spring 10 having one end fixed to the rear base 3. The pin 7 of the link 8 engaged with the longitudinal hole 6 in the front-rear direction of the front base 5 is provided with a torsion coil spring 11 having its coil mounted on the lower surface side of the front base mounting portion of the roof inner frame 2. One end of the pin 7 is in contact with the pin 7, whereby the pin 7 is constantly resiliently biased forward of the slot 6.

Below the slide panel 12, an arm 4 is provided.
Shoes 13F and 13R that can be abutted are provided on the upper surface of. The shoes 13F and 13R are slide panels 1
2 are arranged at an appropriate interval between the front edge side and the rear side.

When the slide panel 12 is opened, the downward pressing force acting on the arm 4 decreases as the shoes 13F and 13R provided below the slide panel 12 move backward, and the arm 4 is resiliently moved by the elastic force of the leaf spring 10. Tilt upward. At the same time, the pin 7 of the link 8 moves forward in the elongated hole 6 by the elastic force of the torsion coil spring 11, and the link 8 stands. Thereby, the blade 9 is automatically raised (see FIG. 2).

When the blade 9 is lifted, the upstanding link 8 prevents the blade 9 from displacing downward, and the arm 7 prevents the blade 9 from displacing backward. Therefore, when wind pressure acts on the blade 9 from the front, the vertical swing is supported by the link 8, and the longitudinal swing is supported by the arm 4. Therefore, according to the configuration of the present invention, a high blade holding force in the front-rear direction and the vertical direction can be obtained.

When the slide panel 12 is closed, the arm 4
Is pushed down by the shoes 13F and 13R, and the blade 9 is stored below the slide panel 12 (see FIG. 1).
At this time, even if the spring constant of the leaf spring 10 for urging the arm 4 upward is set relatively low, it hardly affects the blocking force of the blade 9 in the backward movement. Influence on the sliding resistance can be reduced.

On the other hand, the upward component of the link 8 is
Becomes smaller as the slide panel 12 closes, the influence of the spring force for urging the link 8 in the upright direction on the sliding resistance of the slide panel 12 also decreases. Therefore, according to the configuration of the present invention, the sliding resistance of the slide panel 12 in the closing direction can be reduced.

Here, two sets of shoes 13F and 13R are provided on the front edge side of the slide panel 12 and on the rear side thereof.
First, the front shoe 13F pushes down the arm 4 inclined forward and the rear shoe 13R continuously pushes down the arm 4 when the front shoe 13F comes off the front end of the arm 4.

[0017]

As described above, according to the first aspect of the present invention,
By providing spring means for holding the blade in the raised position separately from spring means for urging the arm supporting the blade upward, the urging force on the arm can be reduced.
It was just enough to raise the blade.
Therefore, since the spring force of the spring means for urging the arm upward can be relatively reduced, the reduction of the sliding resistance of the slide panel and the increase in the holding position of the blade in the ascending position can be made even higher. A great effect can be obtained above. According to the second aspect of the present invention, the spring means for holding the blade at the raised position is a torsion coil spring, and the coil portion is arranged on the lower surface of the roof inner frame. The size does not need to be increased, and the appearance does not need to be impaired.
