JPH09300974A - Free sliding preventing mechanism of sunroof shade - Google Patents

Abstract

PROBLEM TO BE SOLVED: To certainly prevent the free sliding of a sunroof shade caused by vibration during travelling, by arranging a gear part in the predetermined part of the lower surface of the sunroof shade slidably supported on rails on both sides of the roof opening of a car body, and arranging on a car body roof side, a pair of brushes brought in contact with the gear part relative to the gear part. SOLUTION: A shade 1 by which the opening O of a sunroof is closed is slidably supported between both side rails 2, 2 a gear part 4 in which a plurality of triangle cross sectional projections 41 is provided adjacently to the lower surface of the front edge of the shade 1, an brushes 7, 8 are arranged in the front edge of a sunroof frame F and an intermediate lateral beam 6. At the this time, a bruch 9 is inclined to the slant front in the front side brush part 7, and a brush 10 is inclined to the slant rear in the rear side brush part 8. Hereby, the gear part 4 of the shade 1 is pushed and pressed to the side of the brush part 7 by a spring 11, for example, in a fully opening position, and the brush 9 inclined to the slant front is brought in pressure contact with the rear side slant surfaces of the projections 41. As a result, the shade 1 is energized in a forward so as to be prevented from being slid in a closing direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for preventing free sliding of a sunroof shade of an automobile.

[0002]

2. Description of the Related Art As shown in FIG. 1, a sunroof shade
(1) is slidably supported by rails (2, 2) on both sides via sliders (3), and is shown by the dotted line from the fully open position shown by the solid line guided by the rails (2, 2) Slide back and forth to the fully closed position. And conventionally, as shown in FIG.
A shade stopper (14), which is a leaf spring, is attached from the top of the slider (3) of (1) to the shade (1).
In the fully open state or the fully closed state, the stopper (14) contacts the protrusion (15) or the protrusion (16) on the outer upper surface of the rails (2, 2), and the shade (1 ) Is locked so that it does not slide in the opening direction.

[0003]

In the above conventional mechanism, when the shade (1) vertically vibrates while the vehicle is traveling, the stopper (14) gets over the projections (15, 16) and the shade (1) is opened or closed. There is a risk of free sliding in the closing direction. To prevent such free movement of the shade (1)
It is necessary to increase the height of (15, 16) and the rigidity of the stopper (14), but when opening or closing the shade (1), the stopper (14) does not push the protrusions (15, 16). Since you have to get over it, the operating force becomes large and the shade
There was a problem that (1) could not be opened and closed smoothly.

[0004]

As a means for solving the above conventional problems, the present invention is slidably supported by rails (2, 2) on both sides of a roof opening O of a vehicle body. A tooth part (4) having a plurality of protrusions (41) having a triangular or oval cross section is provided at a predetermined position on the lower surface of the sunroof shade (1), and the tooth part (4) is provided at a predetermined position on the vehicle body roof side. ) With a pair of brushes (7, 8) that are in contact with each other, the bristles (9) of one brush (7) are inclined diagonally forward, and the bristles (8) of the other brush (8) are 10) is slanted backward, and one brush portion (7) is in the shade position when the shade (1) is in the fully closed position.
Of the sunroof shade (1) that abuts on the tooth part (4) of (1) and the other brush part (8) abuts the tooth part (4) of the shade (1) at the fully opened position of the shade (1). A free sliding prevention mechanism is provided.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION One specific example of the present invention is shown in FIGS. In this example, as shown in FIG. 1, the shade (1) for closing the opening O of the sunroof is opened from the fully open state shown by the solid line to the rails (2, 2) on both sides through the slider (3) to the full shade shown by the dotted line. It is slidably supported up to the closed state, and is housed in the shade housing section H on the front side of the opening O in the fully opened state. As shown in FIGS. 2 and 3, a tooth portion in which a plurality of protrusions (41) having a triangular cross section are continuously provided on the lower surface of the front edge portion of the shade (1).
(4) is provided and the sunroof frame F front edge (5)
And the brushes (7, 8) on the middle cross beam (6) of the frame F.
Is installed on the front brush part (7).
(9) is slanted forward, and bristles (10) in the rear brush part (8) are slanted rearward.

The slider (3) is inserted into the rail (2) as shown in FIGS. 4 and 5, and the slider (3) is
(3) An arc spring (11) is attached to the top surface,
Thus, the shade (1) is urged downward by the spring (11) through the slider (3) as shown by arrows a in FIGS. 4 and 5.

In the above structure, the tooth portion (4) of the shade (1) is at the front brush portion (7) in the fully open position shown in solid lines in FIG. 1 and FIG.
The tooth portion (4) is contacted with the lower brush portion by the spring (11) as shown in FIG.
The bristles (9) pressed toward the (7) side and inclined obliquely forward of the brush part (7) have a rear slope (41A) of the protrusion (41) of the tooth part (4).
As a result of pressure contact with the tooth (4), a forward component force is generated on the protrusion (41) of the tooth (4) as shown by the arrow B, and as a result, the shade (1)
Is biased in the front direction and is prevented from sliding in the closing direction (rear direction).

Further, in the fully closed position shown by the dotted line in FIG. 1 and FIG. 3, the tooth portion (4) of the shade (1) abuts the rear brush portion (8), but as shown in FIG. As a result, the tooth part (4) is pressed toward the lower brush part (8) side as shown by the arrow a, and the bristles (1
(0) is pressed against the front slope (41B) of the protrusion (41) of the tooth portion (4), and as a result, a rearward component force is applied to the protrusion (41) of the tooth portion (4) as shown by arrow C. As a result, the shade (1) is urged in the backward direction and prevented from sliding in the opening direction (forward direction).

Therefore, in the above construction, even if the shade (1) vibrates vertically during traveling of the vehicle, the shade (1) is prevented from freely sliding at the fully open position and the fully closed position.

Other than the above specific example, the tooth portion of the shade and the brush portion on the roof side may be arranged at any position as long as the tooth portion and the brush portion are in contact with each other at the fully opened and fully closed positions of the shade. The tooth portion may be provided on both side edges of the slider, and the brush portion may be provided inside the rail. Further, as shown in FIG. 8, the protrusion (24A) of the tooth portion (24) may have a circular cross section. Further, the shade may be supported by inserting the both side circles directly into the rail without using a slider.

[0011]

According to the present invention, the free sliding of the sunroof shade due to the vibration while the vehicle is traveling can be reliably prevented, while the shade can be easily opened and closed. Also, the protrusion shape of the teeth and the rigidity, height, density of the bristles of the brush,
By adjusting the contact area between the tooth and brush,
It can also be used for various sunroof shades.
