Description

"Lift and sliding roof at the front ends of the panel supports,

  The invention relates to a lifting and sliding roof for vehicles comprising a panel used to close or to release-at least partially a roof opening, this panel carrying in its front zone and on the side and other front guide members that are guided from

  adjustable way along the intended guide rails

  on the roof opening by being connected to the

  fixed part of the roof, and, the panel, starting from a

  closure can come in an inclined position

  by raising its rear edge and being moved into position

  opening, backward over the, part

fixed roof.

  Lift and sliding roofs of this type are already known, which are also called "roof-fins". These roofs are particularly suitable for motor vehicles in which the available height is limited, as is above all the case for motor vehicles, relatively small, so as to have a low coefficient cw (low air penetration coefficient> to save energy To prevent the penetration of air currents, dust and rainwater inside the vehicle when the panel is closed, it is necessary to provide at the edge of the opening

  roof and / or along the edge of the panel, an elastic joint

  which is generally made of rubber or a material having similar elastic characteristics In the case of known roof-ailerons, this seal is often stressed not only by the influence of bad weather but also by considerable mechanical stresses, especially in level of the front edge of the roof opening or panel Damage may result

premature seal.

  The present invention aims to create a

  roof lift and sliding which, despite a simple structure

  solid and robust, maintains at a particularly low level the mechanical stresses exerted on the joint

of the panel.

  To this end, the invention relates to a lifting and sliding roof of the above type, characterized in that the front ends of the panel supports supporting the panel are hingedly connected in tilting manner on the front guide members and the tilting axis. panel (articulation> is in front of the front edge of the roof opening when the panel is in

closing position.

  Such means avoid the descent of the front edge of the panel under the front support surface of the panel When raising the panel, the front edge is also raised This avoids excessive compression of the seal

at the front edge of the panel.

  Other features of the invention are

  stated in the description and in the claims.

  The present invention will be described in more detail with the aid of the accompanying drawings, in which: FIG. 1 is a view from above of a vehicle

  motor with a sliding and sliding roof according to the

  vention. Figures 2 to 4 are longitudinal sections of the rising and sliding roof, according to the line II-II of the

  Figure 1 for three different use positions.

  Figure 5 is a partial longitudinal section

  of an alternative embodiment of the invention.

  As shown in the figures, at the level of the

  1 of a motor vehicle A, there is provided a roof opening 2 This roof opening 2 is surrounded in the embodiment of the invention according to FIGS. 1 to 4 by a joint 3 whose section essentially corresponds to a shape of L Below the roof 1 is a roof frame 4 which limits upwardly the passenger compartment of the vehicle A The roof frame 4 is at the level of the opening of the roof 2, shifted towards down at a certain distance from roof 1 and surrounds

  thus a frame opening 5 corresponding to the opening

roof 2.

  Straight guide guides 6 are provided on the upper face of the roof frame 4 on both sides of the roof.

  the roof opening 2 The guide rails 6 are essentially

  parallel to the roof opening 2, in the

  longitudinal direction of the vehicle A transport trolley

  port 7 as well as adjustable guide members 8, 9 front and rear slide forward or backward along the guide rails 6 The transport carriage 7 comprises a member 11 which is connected via a drive means such as for example an electric motor or a crank and a drive member 10 for example in the form of an incompressible threaded cable The member It carries two sliding parts 12, projecting laterally and who

  cooperate with the guide rail 6 The sliding parts

  12 and the guide members 8, 9 may preferably be sliders of synthetic material or the like, having in side a substantially elliptical shape, and which engage in guide rails 6 preferably channel-shaped for slide

along the guide rails.

  For closing or selective opening of the roof opening 2, there is provided a rigid panel 13 this panel can be made for example of glass, plastic, sheet metal or the like that is to say that it may be a transparent, translucent or opaque material In the closed position, the edge of the panel 13 bears against the seal 3 In this case, in particular, the underside of the panel is pressed against the face

  upper part of a lower part 3 of the joint 3

  The water 13 is supported via fastening means not shown on two panel supports 14.

  opposed each of the two panel supports 14 is articulated

  at its forward end on a guide member

  before 8, respectively and can turn around an axis

  transverse formed by a hinge 21.

  A lifting lever 15 is provided on both sides of the roof opening 2. Each of the lifting levers is pivotally supported on the corresponding rear guide member 9 at its central portion while the rear end the lift lever is

  connected to the corresponding panel support 14 through

  The transport carriage 7 and the lifting lever 15 cooperate by means of a cam or slide arrangement 16, 17 provided in the middle part of the lifting lever. In the embodiment shown, the slide assembly comprises the front and rear slide shafts 16a, 16b of the transport carriage 7 and the rear slide slots 17a, 17b of the lift lever 15. slide axis can also

  be provided on the lift lever and the clevis

  smooth can be provided in the transport trolley The

  slot slider 17 a, before, which is essential

  the axis formed by the guide member 9 is straight in front of the pivoting axis of the lifting lever, whereas the slit 17b which is located behind the tilting axis of the lifting lever 15 has a straight line. rectilinear front segment, parallel to the slide axis 17a and an adjacent segment, rear, curved towards

  the bottom of the slide shafts 16 a, 16 b are

  In the same way, the front slit 17a and the rectilinear segment of the rear slit 17b are practically the same height.

  at the same height in the closed position of pan-

  In the closed panel position, the slide pins 16a, 16b (as shown in FIG. 2) are essentially symmetrical with respect to the axis of rotation of the lifting lever 15, which axis is formed. by the rear guide member 9 The slit slot 17a and the segmentrectiligne of the slit slot 17b are in the vicinity of the upper edge of the lift lever 15 while the curved segment of the slit slot 17b arrives until 'in the vicinity of the lower edge

lift lever 15.

  If from the position of Figure 3 in which the panel 13 is above the roof opening 2 and the rear edge of the panel is in the raised position above the fixed part of the roof to ensure aeration the transport carriage 7 is pushed forward by the drive member 10 and the slide pins 16a, 16b slide forward into the slots

  slide 17 a, 17 b As long as the axis of cut

  smooth 16 b thus traverses the curved back segment of

  the slit slit 17 b, the lift lever 15 down-

  in a clockwise direction (FIG. 3) around the axis of rotation formed by the guide member 9 This results in a tilting movement of the panel support 14 around the hinge 21, so that that the rear edge of the panel moves down This closes the opening 2 of the roof During the movement thus described,

  the slide axis 16a, before, pushes against the upper edge

  the rear slide pin 16b pushes on the lower edge of the rear slide slot 17b The transport carriage 7 then continues to move forward, so that

  the slide axis 16b passes into the segment before rectification.

  line of the sliding slot 17 b The result is the

  ratching of the panel 13 in the closed position During the advance movement of the slide pins 16a, 16b in the slits 17a, 17b, the panel 13 is blocked

  in its forward movement by a corresponding abutment

  or simply because the front edge of the

  the water rests against the protruding part 3b of the gasket 3

  at the front edge of the roof opening 2.

  If, on the other hand, starting from the position of FIG. 2, the transport carriage 7 is pushed backwards by means of the driving member, the slide pins 16a, 16b move towards the back in the slits 17 a, 17 b

  first, the lock of the pan is unlocked.

  Then the lift lever 15 switches counterclockwise (Figure 2> around

  of the axis of rotation formed by the guide member 9.

  As a result, the panel support 14 tilts and rises around the axis of the hinge 21 and the rear edge of the panel 13 rises as shown in FIG.

  slides and the hinge 18 connecting the lever of rele-

  15 and the panel support 14 is greater than the

  distance between the slide assembly and the guide member

  9 which forms the axis of rotation of the lifting lever, it is obtained that the hinge 14 is relatively raised relatively, although the vertical distance between the highest position and the lowest position of the slide axis 16 b in the slit slit

  17 b is relatively weak This last characteristic

  tick offers the advantage that the lifting device of the

  roof lift and sliding occupies only a relative volume

  low in vertical height and only

  very little room in the roof of the cabin.

  The front end of the lifting lever 15 is in

  protruding forward beyond the axis of rotation (or-

In this way, the guide element 19 cooperating with the guide member 9 and the guide rail 6 can hold the lifting lever 15 in the tilted position. according to Figures 3 and 4 This

  provides some support to the panel 13.

  On the other hand, if the panel 13 is driven from its position

  raised (Figure 3) to its closed position (fi

  2), the guide member 19 disengages from the blank

  off the guide rail 6 When starting from the

  2, the transport carriage 7 moves backwards, the guide element 19 bears against a bearing surface 20a at the cutout 20, which

  which prohibits the sliding of the panel 13 to the rear.

  This ensures that during the movement of the transport trolley

  port 7 to the rear, the panel 13 is first raised before the panel 13 is driven towards

  the rear by the transport trolley 7.

  As long as the panel 13 is aligned with the roof opening 2, the hinge 21 which supports the panel support 14 is on the guide member 8, before, in front of the front edge of the opening If after this, the panel 13 is moved from the closed position (Figure 2) to the raised position

  (FIG. 3), the front edge of the panel 13 is recovering progressively

  The front edge of the panel is no longer lowered

  below the support plane of the panel formed by the lower part 3 of the seal 3 This avoids the seal 3 is exposed to troublesome stresses during the lifting movement of the panel 13 In addition, the displacement towards the before the axis of rotation of the support

  panel 14 improves the stability of the entire

  because of the relatively long lever arms.

  If, starting from the position of Figure 3, the transport carriage 7 is moved further back and entrains the panel 13 by abutting the slide pins 16a, 16b against the ends

  behind the slits 17a, 17b, the guide member

  9 and the guide element 19 which both move in the guide rail 6, maintain the lifting lever 15 in the lifting position. The panel 13 can thus be placed in the open position according to FIG. gives a particularly rigid and robust mounting In addition, the fact that the articulation 18 is

  located between the panel support 14 and the lift lever

roof 2.

  FIG. 5 shows an alternative embodiment which differs from the embodiment described above essentially in that in place of the seal 3 which surrounds the roof opening 2, there is a seal 23 surrounding the edge of the panel 13 whereas in Figures 2 to 4, the panel is represented as a glass panel,

  in the case of Figure 5, a panel 13 in tale.
