Abstract

PURPOSE: To automatically open ventilating ports by constituting so that a spring element can be released by a cover turned to a ventilating position in a vehicle roof where the ventilating ports and a closing member to open and close the ventilating ports by being energized by a spring are arranged in a freely slidable shade arranged under the cover. CONSTITUTION: A roof opening part 2 arranged in a vehicle roof l can be selectively closed by a cover 3, or can be at least partially opened, and a shade 4 is arranged under this cover 3 so as to be freely slidable in the longitudinal direction. In the shade 4, plural slit-like ventilating ports 5 are arranged in a rear range, and the ventilating ports 5 are opend and closed by a closing member 6. In this closing member 6, the rear end is joined to the closing member 6, and the front end is energized in the opening direction by a curved leaf spring 7 joined to a fixed point of an upper surface of the shade 4, and when the cover 3 exists in a closing position, since the spring 7 is pressed and deformed by a pushing-down member 11, the closing member 6 is displaced to the closing position.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a vehicle roof that can be opened and closed.

[0002]

The present invention comprises a cover for selectively closing or at least partially releasing the roof opening of a fixed roof shell, and a slidable shade disposed below the cover. An openable vehicle roof of the type in which the shade is provided with at least one ventilation opening and at least one closure member actuated by at least one spring element to close or at least partially open the ventilation opening.

A vehicle roof of this kind is known from European Patent Application Publication No. 0150470.

[0004]

In the case of this vehicle roof, the ventilation opening provided in the shade is arranged above the shade when the cover is raised to the ventilation position by the sliding of the closing member by the free end of the drive cable. It is released by the spring-loaded grill in the closing direction by the spring. That is, in the case of this type of vehicle roof, the ventilation opening is necessarily opened whenever the cover is moved to the ventilation position. This prevents the driver from individually actuating the shade because the opening movement is associated with driving the cover.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle roof which can be freely opened and closed and which can automatically open a ventilation opening at a ventilation position regardless of a cover raising mechanism.

[0006]

This object is solved according to the invention by the features of claim 1. Advantageous embodiments of the invention are disclosed in the dependent claims. The spring element pre-loads the closing member in the opening direction and the cover pivoted to the ventilation position above the fixed roof shell or a member connected to said cover is capable of opening the spring element, on the one hand, pivoted upwards. The cover opens the closure member as the spring element is released.

On the other hand, however, any position of the shade can be adjusted manually, independent of the cover position.
This is because the spring element slides in the longitudinal direction of the vehicle together with the shade in the loaded state. It is advantageous if the spring element is pivotally attached at one end to the closure member and at multiple ends to a fixing point on the upper surface of the shade. Fixing it on the upper surface of the shade does not impair the visual impression of the shade from inside the vehicle.

Furthermore, it is advantageous if the fixing point can move the spring element. Due to such displacement, one end of the spring element causes further compression when lowering the cover of the slide-tilt roof before sliding rearward below the fixed vehicle roof surface. The spring element is constructed in a particularly simple manner as a curved leaf spring. It is advantageous to provide the other end of the spring element with a through bore for supporting the leaf spring on a guide rod extending parallel to the longitudinal direction of the leaf spring and forming a fixed point.

According to a preferred embodiment, the closure element is constructed so as to be movable parallel to the shade. According to a modification of the embodiment described above, the closing member is constructed so as to be movable vertically to the shade. In this case, the shade shielding effect is almost completely obtained even when the ventilation port is completely opened. According to another advantageous embodiment, the closure element is pivotally mounted on the shade. Also in the case of this modification, a partial shielding effect is still obtained when the ventilation port is open.

According to an advantageous embodiment of the invention, the spring element or the closure element can be fixed by a locking element so that the closure element remains locked in the closed position even when the cover is raised.

FIG. 2 is a view of the vehicle roof of FIG. 1 with the cover raised and the vents open. 3 is a drawing of the vehicle roof of FIG. 1 with the cover lowered and the ventilation port closed. FIG.
It is an expanded partial perspective view of the shade of FIG.

FIG. 5 is an enlarged partial perspective view of the shade shown in FIG. FIG. 6 is an enlarged partial perspective view of the shade of FIG. FIG. 7 is a longitudinal sectional view of the shade and the vertically movable closure member. FIG. 8 is a schematic vertical sectional view of a shade and a closing member pivotally supported. FIG. 9 is a schematic longitudinal sectional view of a closure member indirectly actuated by a shade and a cover.

The roof opening provided in the fixed vehicle roof 1 can be selectively closed or at least partially released by means of a cover 3. Therefore, the cover 3 is supported by guide mechanisms (not shown) provided on both sides of the roof opening 2 by a slide mechanism (not shown) in a known manner. In the case of the embodiment shown, the vehicle roof is constructed as a slide-tilt roof and the cover 3 can be raised in a known manner to the ventilation position above the stationary vehicle roof 1 (FIG. 2) or the cover trailing edge is fixed. It is possible to descend below the vehicle roof 1 and then slide the cover rearwardly below the fixed roof (FIG. 3).

Below the cover 3, a shade indicated by 4 is slidably supported in the vertical direction. Shade 4
It is advantageous to provide a plurality of slit-shaped ventilation openings 5 in the rear area. The ventilation opening 5 can be selectively closed or at least partially released by one or more closure members 6. The closing member 6 is slidably supported on the upper surface of the shade 4 in the vertical direction. The closing member is arranged in parallel to the slit-shaped ventilation opening 5 and is composed of a plurality of webs having a width such that the ventilation opening 5 can be completely closed from the upper surface.

The closure member 6 is also pivotally attached to the shade 4 by a spring element 7. In this case, the spring element 7
Advantageously, the rear end is connected to the closure member 6 and the front end is connected to a fixed point 8 on the upper surface of the shade 4 as a curved leaf spring. As is apparent from the enlarged views of FIGS. 4 to 6, the fixing point 8 is advantageously configured as a guide rod 9 surrounded by a spring element 7 having a through bore 10. Due to this supporting state, the front end of the leaf spring 7 can slide in the longitudinal direction of the vehicle.

The spring element (leaf spring) 7 is elastically preloaded in the bent state, thus loading the closure member 6 in the opening direction, ie in the forward direction. On the upper surface of the spring element 7, the cover 3 itself or a push-down member 11 connected to the cover abuts on the upper surface of the spring element 7 at approximately the center of the curvature caused by the curvature. In this case, the push-down member 11 is preferably provided on the cover panel, the cover blind, or the cover connecting mechanism. In this case, if the preload of the spring element 7 raises the cover 3 and thus allows the spring element 7 to be released, the degree of curvature of the spring element is increased.

Therefore, unless one end of the spring element 7 is slidably supported, the preload of the spring element 7 increases as the cover 3 descends. The slidable support in the form of the guide rod 9
Advantageous, but not necessary. This is because the spring element 7 can escape downwards with a corresponding loop configuration even under high preload conditions. As shown in detail in FIGS. 4-6, the webs of the closure member 6 are joined to each other at the sides by joining bars 12. The width of each web approximately corresponds to the width of the slit-shaped ventilation opening 5. The connecting bar 12 is guided on both sides by a guide bar 13 fixed to the upper surface of the shade 4 so as to be vertically slidable.

In this case, sliding is limited to the width of the guide slit 5 by the front and rear stoppers 14. Shade 4
Can be vertically slid along a guide provided on the stationary vehicle roof 1 by means of a sliding shoe 15 engaging with the guide, regardless of the position of the cover 3. Figure 4-
6, the front end of the spring element 7, when slidably supported by the guide rod 9, can be further preloaded by an auxiliary spring 16, thus the front end of the spring element 7 is above-mentioned when the cover 3 is closed or raised. It is moved to the rearmost position under the effect of the force of the auxiliary spring 16.

The function of the vehicle roof will be described below. When the cover 3 is closed (see FIGS. 1 and 4), the spring element 7 loads the closing member 6 forward in the opening direction. However, since the push-down member 11 prevents the leaf spring 7 from escaping upward, the ventilation port 5 is closed. When the rear edge of the cover 3 is raised to the ventilation position, the push-down member 11 which pivots upward together with the cover 3 releases the spring element 7, thus increasing the degree of curvature of the spring element and keeping the position of the front end unchanged. The closing member 6 is opened as the rear end moves forward. This opening takes place stepwise to an intermediate position if the cover 3 is not completely raised.

Whether the cover 3 is in the closed position or the cover 3 in the ventilated position, the complete shade 4 is independent of the opening of the ventilation opening 5.
Can be manually slid rearward below the fixed vehicle roof 1. In this case, the spring element is pressed flat by a depressing member (not shown) connected to the stationary vehicle roof, in which case the front support point of the guide rod 9 is
It is moved forward against the force of the auxiliary spring 16.

Similarly, the cover 3 of the slide tilt roof
However, when the rear edge of the cover descends (FIGS. 3 and 6), the pressing member 11
Even when the spring element 7 is pressed from above by the above, the movement of the front fixing point of the leaf spring 7 occurs. In this position, the closure member 6 closes the ventilation opening 5. In the case of a particularly advantageous embodiment, the operator can also determine, via locking means that can be operated from below the shade 4, whether the opening of the ventilation opening 5 is desired. For this purpose, one is provided with a locking element 17 which is slidably arranged in front of the fixing point 8 on the shade 4 and which can fix the spring element 7 in the loaded position, ie in the closed position of the closing member 6. .

When the U-shaped locking element 17 is slid forward, the spring element 7 is free to move. The locking element, which is slid backwards, blocks the release of the spring element 7. Instead of sliding, the locking element 17 can be arranged to rotate with respect to the shade 4. Another way of locking the spring element 7 is--as shown in FIG. 4--in the locked position blocking the opening of the closing member 6 and the release of the spring element 7, for example:
The eccentric locking means 18 may be rotatably supported on the shade 4.

The locking of the spring element 7 or the closure member 6 is
It is also advantageous when the shade 4 slides rearward. This is because thus the wear of the leaf spring 7 by the push-down member fixed to the roof is prevented. Locking means 17; 1
8 has been shown and described in combination with a leaf-spring-like spring element 7 and a closure member 6 which can slide parallel to the shade, but such an element is similar in the case of the embodiment of FIGS. It can be used advantageously.

According to another embodiment shown schematically in FIG. 7, it is also possible to move the closing member 6A in the vertical direction by means of two spring elements 7A provided at the front and rear edges of the shade 4A. In the case of such a configuration, it is advantageous if the cover 3 or the pressing member 11 thereof does not act on the spring element 7A but directly on the closing member 6A from above.

According to another advantageous embodiment, which is shown diagrammatically in FIG. 8, a closure member 6B is pivotably mounted on the shade 4B. In this case, the spring element 7 provided at the trailing edge of the shade
B loads the closing member 6B in the opening direction. As soon as the cover 3 or its push-down member 11 is swung upward to the ventilation position, the ventilation port 5B is opened. This vent is closed as soon as the cover is lowered to the closed position.

In the case of another embodiment of FIG. 9, the tension spring 7 is used.
The closing member 6C, which is preloaded in the opening direction by a C-shaped spring element, serves to close the cover 3 when the cover 5 is closed.
Close C. The closing member 6C is held in the closed position by a thrust element 19 which abuts on one end a stopper of the closing member 6C and on the other end abuts the cover 3 or a push-down member 11 connected to the cover.

The thrust member 19 is flexible, and is guided by a guide 20 provided on the upper surface of the shade 4C so that it can be pressed and pulled. The guide 20 can be configured either as a stationary coupling mechanism or as a sleeve of Bowden wire. If the cover 3 is raised, the thrust element 19
Can be moved and thus the closure member 4C can be opened. With a vehicle roof according to the invention of a simple construction, at least one ventilation opening of the vehicle shade can be automatically opened and the entire shade can be slid regardless of the mechanism of the cover.
