Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding roof that is located between a roof panel having an opening and a housing installed below the roof panel, and is slidably installed on rails laid on both sides of the opening of the housing. The present invention relates to a tint deflector for a sunroof of an automobile, which is equipped with a sunroof whose opening is opened and closed by a panel.

FIG. 1 is a plan view showing the entire sunroof of an automobile in which an opening 2 of a roof panel 1 is opened and closed by this type of sliding method.

As shown in the figure, in this type of automobile, a housing 3 is attached below the roof panel 1, rails 5 are laid on both sides of the opening 4 of the housing 3, and the sliding roof panel 6 is attached to the front and rear shoes 7. It is slidably attached to the rails 5, 5 via the opening 2 and can be opened and closed.

When the sliding roof panel 6 is closed, its top surface and the top surface of the roof panel 1 are required to be on the same plane, and generally there is a hop between the sliding roof panel 6 and the rear shoe 8. An uplink mechanism (not shown) is provided to raise and lower the rear part of the sliding roof panel 6 in conjunction with its opening and closing operations, and the rail 5.5 is sloped upward in the forward direction of the vehicle.

The sliding roof panel 6 is slid by pulling or pushing the shoes 7 or 8 on the front or rear side with a cable (not shown) connected to a drive motor or the like.

By the way, in a car equipped with a sliding type sunroof configured as described above, when the sliding roof panel 6 is opened, the wind from the vehicle may be drawn into the interior of the vehicle.To prevent this, the sliding roof panel 6 is closed. A wind deflector that moves up and down on the front side of the opening 2 may be provided in connection with the opening/closing operation.

FIG. 2 shows an example of a conventional wind deflector.

As shown in the figure, in this conventional example, a lift arm 9 is rotatably attached to a part of the rail 5 of the housing 3, and a wind deflector 11 is rotatably attached to the tip end of the rail 5 via a hinge 10. A bracket 13 having a long hole 12 is attached to the back side of the wind deflector 11, and a pin 14 is formed protruding from the tip of the lift arm 9.
is inserted into the elongated hole 12, and a spring 15 is provided between the wind deflector 11 and the rail 5 to urge it outward.

The lift arm 9 is sequentially pressed downward at the end of its closing operation by an engaging member 16 provided on the tip side of the sliding roof panel 6, and is sequentially released at the beginning of its opening operation.

During the opening operation of the sliding roof panel 6 in which the lift arm 9 is released from the engaging member 16, as the operation progresses, the wind deflector 11 receives the urging force of the spring 15 and moves counterclockwise in the figure. rotate,
The lift arm 9 rises while the pin 14 at its tip moves freely within the elongated hole 12.

As a result, a portion of the wind deflector 11 protrudes from the opening 2 of the roof panel 1, thereby deflecting the traveling wind outward.

On the other hand, in the closing operation of the sliding roof panel 6 in which the lift arm 9 is pressed down by the engaging member 16, the lift arm 9 moves down as the closing operation progresses, and the wind deflector 11 is moved against the spring 15. and rotate it clockwise to store it between the sliding roof panel 6 and the housing 3.

However, such a conventional wind deflector 11
Since the pivot point is on the housing 3 rule 5, the total length of the roof panel 1 becomes longer because a part of the roof panel 1 protrudes outward from the upper surface of the roof panel 1, resulting in an increase in the storage space. there were.

In addition, the amount of protrusion of the wind deflector 11 is small, and there is a drawback that the wind from the vehicle cannot be sufficiently deflected.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the conventional sunroof tip deflector, the present invention aims to improve the above-mentioned defects and provide a small overall length with a large protrusion and a small storage space.

The structure of the present invention will be explained below according to the embodiments shown in the drawings.

3 to 8, 17 is a hinge for pivotally supporting the lift arm 18 midway on the forward direction side of the rail 5;
19 is a leaf spring installed between the rail 5 and the lift arm 18 that urges the lift arm 18 upward; 20 is a wind deflector having a rear end bulge 21.21 pivotally supported at the tip of the lift arm 18; , 22 is a torsion bar installed between the wind deflector 20 and the lift arm 18 which rotates the wind deflector 20 clockwise to urge it to rotate substantially in a straight line with the lift arm 18.

There is a stepped portion 2 at the pivot point of the lift arm 18 and the hinge 17.
3, and the rotation angle of this lift arm 18 is set to a predetermined angle by the stepped portion 24 of the hinge 17.

Further, as clearly shown in FIG. 7, a bulge 25 is formed on the upper surface of the tip of the lift arm 18 which is sandwiched between the bulges 21 and 21 of the wind deflector 20 and pivotally supports it. When the deflector 20 is stored, its end portion 26 is locked to set the posture of the wind deflector 20 at a predetermined angle.

Reference numerals 31 and 32 indicate a wind deflector 20 configured on the lift arm 18 and the lower blade of the pivot portion of the wind deflector 20.
This is a stepped portion for setting the rotation angle when protruding.

27 is a weather strip rubber fitted to the front edge of the wind deflector 20, 28 is a weather strip rubber fitted to the edge of the sliding roof panel 6, and 29 is a resin attached to the lower surface of the tip of the sliding roof panel 6. A fixing piece 30 formed by protruding the bottom side of the end face of the housing 3 in the forward direction is a seating surface when the wind deflector is stored.

The wind deflector 20 of the present invention includes 1 and a lift arm 1.
8 rotates upward, the weather strip rubber 28 fitted on the front edge thereof slides in contact with the back surface of the roof panel 1, and is locked to the back surface of the edge and rotates with the pivot shafts 18a and 20a. It is characterized by maintaining that posture.

In detail below, when the sliding roof panel 6 is in the closed state shown in FIG. It engages with the protruding portion 25, and its rotation angle is restricted to a substantially horizontal state so as to be in line with the lift arm.

Further, the weather strip rubber 27 is seated on the seating surface 10 of the housing 3 at the center, thereby preventing jitters and the like during driving.

When the sliding roof panel 6 is opened from this state, the lift arm 18 held by the fixed piece 29 is sequentially released and rotated clockwise about the pivot 18a by the biasing force of the leaf spring 19. .

Wind deflector 20 and lift arm 1 in this case
The relationship 8 is the attitude of the figure 3.

When the tip of the lift arm rises and the weather strip rubber 27 of the wind deflector 20 comes into contact with the back surface 1a of the roof panel 1, the lift arm 18 at this contact portion
Rotation about the pivot 18a is prevented.

However, the lift arm 18 is still rotating clockwise, and the rear end of the wind deflector 20 continues to rotate along the tip rotation trajectory of the lift arm 18, that is, the rotation trajectory of the pivot shaft 20a. , the lift arm 18 stops at a position where the stepped portion 23 of the lift arm 18 engages with the stepped portion 24 of the hinge 17, as shown in FIG.

Therefore, the wind deflector 20 has a torsion bar 22
The weather strip rubber 27 is rotated and displaced relative to the lift arm 18 against the applied force of the roof panel, and the weather strip rubber 27 slides into contact with the back surface 1a of the roof panel opening edge and is locked there as shown in FIGS. 6 and 8. be done.

This allows the wind deflector 20 to be attached to the roof panel 1.
The posture of the shafts 18a and 20a and the weather strip rubber 27 when protruding from the upper surface to perform a wind regulating action is
The wind deflector 20 can be made to protrude almost the entire length (width in the longitudinal direction of the vehicle) from the roof panel 1 to perform a wind regulating function.

Therefore, the overall length of the wind deflector 20 can be reduced to obtain a large amount of protrusion, and the storage space can also be small.

On the other hand, when the sliding roof panel 6 is closed, the fixing piece 29 is attached to the lift arm 18 at the final stage.
The wind deflector 20 can be retracted into the state shown in FIG. 3 by pressing down and reversing the above operation.

Therefore, detailed explanation here will be omitted.

As explained above, the present invention is installed between a roof panel having an opening and a housing attached below the roof panel so as to be able to slide freely on rails laid on both sides of the opening of the housing. In an automobile equipped with a sunroof in which the opening can be opened and closed by a sliding roof panel, the rear end of a lift arm that is linked to the opening and closing operation of the sliding roof panel is provided at the front part of the rail or housing. A spring member is provided between the rail or the housing and the lift arm to constantly urge the lift arm upward, and a spring member is provided between the rail or the housing and the lift arm, and the tip of the lift arm The wind deflector provided along the front edge of the roof panel opening is arranged in a substantially horizontal position, and its rear part is attached to the tip of the lift arm so that it can freely rotate downward over a predetermined angular range. A spring member is provided between the wind deflector and the lift arm, which always urges the wind deflector to rotate horizontally with a force weaker than the rotational force of the lift arm, and when the lift arm is raised, a spring member is provided. The front opening edge of the roof panel is placed on the rotation locus of the tip of the wind deflector, and while the lift arm is rising, the tip of the wind deflector is brought into contact with the back side of the opening edge and the wind deflector is automatically rotated. Because the roof panel is opened, the wind deflector stands up dynamically, allowing the wide wind deflector to protrude from inside the small housing at the top and bottom, resulting in excellent wind regulation. can be provided.

Therefore, although the wind deflector is large, its storage space can be reduced.
