Description

The present invention relates to a panel car sunroof

  rigid, sliding and lifting, guided by front pads

  and rear on slides attached laterally to an inter-

  medial in a cutout of the roof, driven by cables guided with rigidity in compression and acting on the rear pads, pivoting about a horizontal axis, perpendicular to the direction of sliding, on bearings fixed on the front pads,

  and equipped with guide slides fixed on its sides and in the-

  which penetrate guide pins mounted on the rear pads, so that from its closed position, the movable panel can either be tilted over the flag by raising its rear edge, as hinged ventilation flaps at the front, slide under the flag after lowering its rear edge; and the lower face of the movable panel is connected to a lining constituted by two parts of flat shape, the lower part of which does not participate in the pivoting movements of the movable panel and comprises in the rear zone of the cutout of the roof a cutout

  in the closing and sliding positions

  of the movable panel, is covered by the second part, hinged on the lower part and a spring is automatically rotated upwards as soon as pushers coupled to the guide pins

  allow this pivoting movement during opening movements.

the mobile panel.

  A known sunroof with a sliding and liftable panel of this type (Federal Republic of Germany patent application No 26 48 664) does not take account of easy and quick accessibility to the functional parts of the sunroof. , covered by the lining fixed on the underside of the movable panel,

  while this factor is important for assembly and maintenance.

  When the lining is moved relative to the closed mobile panel of the known sunroof, the pushers can no longer perform their function due to their position, so that the springs automatically open the hinged portion of the lining. This open part makes it difficult to handle the upholstery during assembly and maintenance of the sliding and sliding roof sunroof. This packing is furthermore constituted by numerous spare parts, such as hinges and springs, so that its production is expensive. The known packing is furthermore essentially made of

sheet and consequently very heavy.

  The invention aims to achieve the lining of a sliding roof sliding panel and lift the aforementioned type, so as to allow its mounting and easy and quick disassembly in the position of

  covering the underside of the movable panel.

  According to an essential characteristic of the invention, the lateral edges of the lower portion of the lining slide relative to the movable panel; and a locking element, fixed on the lower part, automatically blocks the opening movements of the articulated part of the lining in its fully closed position,

  during the relative sliding of the lower part of the

wise.

  The invention allows a quick and tool-free assembly and disassembly of the lining, which slides relative to the panel to do this

  closed cell, the automatic locking element ensuring the closing

  ture of the hinged portion of the lining, that is to say its fixing flat on the bottom, as the lining is outside its normal position of establishment. The lining slides easily and without additional intervention, the movable panel being

  closed, under the rear part of the pavilion, that is to say in the

  the intermediate frame, so that the underside of the movable panel and all the functional parts are clear and easily accessible. Any adjustment operations on the elements

  height adjustment of the movable panel and on the parts of

  can be easily and quickly

  during the initial assembly of the roof only during subsequent interviews.

  After the end of these operations, the lining is again brought back to its normal position by sliding forward, until it is fixed in a known manner with respect to the movable panel, by

  snap, for example. In this position, the locking element

  the lage again automatically released the articulated part of the

  nissage, that the pushers keep closed when the movable panel

2 4 9 9 9 1 4

  is closed. The articulated part of the lining is thus kept

  by the pushers or by the locking element, according to the

  position of the packing with respect to the movable panel.

  According to another advantageous characteristic of the invention, the locking element is slidably guided on the lower part of the lining and on a short distance of locking or unlocking in the sliding direction of the latter, and slidably actuated by a relatively fixed piece. The automatic action of the locking element is obtained as follows: during sliding of the lining with respect to the closed movable panel, the locking element strikes a relatively fixed piece, so that the opening movements of the part articulated

  packing are blocked or released in the direction of sliding.

  The articulated part is blocked during the sliding of the garnish

  wise backwards, but is released during the forward sliding, towards the normal position of the lining, as soon as the position in which the pushers act again is reached. According to another advantageous characteristic of the invention, the locking element is in the form of a slider, a fixing projection of which penetrates into an oblong hole of the part

  the bottom of the lining and which, upon impact on the

  fixed during the relative sliding of the said lower portion

  upper, slide along the length of the oblong hole and, the sliding

  relative, continuing and elastically deformed by its

  floor. These provisions ensure that the locking element does not hit the relatively fixed piece by limiting the stroke, but can continue its course with the lower part of the lining, after unlocking or locking the articulated portion of the

  lining produced by this piece to which he escapes by a deform-

  elasticity, facilitated by its docking faces. The dimensional stability of the locking element is however sufficient to ensure the desired locking or unlocking of the part

  hinged packing before elastic deformation.

  Maneuvering the locking element does not require any parts

249991 4

  additional. The known water deflector (Br; - and German Federal Re-builder No. 25 32 187), articulated on the guide slides, slidably guided on the slideways and placed under the gap between the rear edge of the term mobile panel and the rear edge of the roof cut, may be provided for the

  sliding operation of the locking element.

  In order to reduce the number of pieces of the lining, and according to a

  Another advantageous feature of the invention is that the lower

  The upper and articulated lining are connected by spring blades bandaged in the direction of the opening movement. Additional hinge parts are thus avoided because the blades of

  bandaged spring simultaneously assume the function of articulation.

  According to another characteristic of the invention, the lower part

  the lining has at least one

  wise sliding, projecting on its underside and which, during relative sliding of the lower part of the

  movable panel, slides on the intermediate frame

  nishing. This prevents the deterioration or fouling of

  wise, normally lined with a light cloth, when it is moved backwards, into the frame of the middle frame, to clear the

bottom side of the movable panel.

  According to another characteristic of the invention, the lower part

  the top of the lining has snap-on bosses on its upper face, which make it possible to couple the lining to the crossbar connecting the front glides, in a known manner (Republic Patent

  Federal Republic of Germany No. 25 51 335).

  According to another characteristic of the invention, the two parts

  The packing elements are produced in a lightweight material and have good dimensional stability. According to another advantageous characteristic of the invention, the parts of the lining are molded in plastic material with simultaneous forming in one piece of all the bosses, cutouts and other elements. This results in

  relatively low production costs and weight.

  According to another characteristic of the invention, the lower part

  The top of the lining is slidably mounted on branches of the opposite slides, to ensure the assembly and sliding of the lining. Other features and advantages of the invention will be

  better understood using the detailed description below of a

  roof in a different position.

  The fixed flag 1 of a car comprises a cutout 4 which

  forced by an intermediate frame 2 and closable by a panel

  3. Slide rails 5 are attached to the sides of the frame

  intermediate 2 for guiding the movable panel 3; only the slide

  left is shown in Figures 1, 2, 3 and 5, and is symmetrically

  at the right slide with respect to a plane. The movable panel is slidably guided on the slides 5, by a front pad 6

  and a rear skid 7 on each side.

  As shown in Figures 2, 3 and 5, the slides 5 are provided with channels 8 against undercut for the cable housing

  drive. The latter, of which only the left cable 9 is

  FIG. 3 shows a fixed drive connection with the rear shoes 7. The drive cables comprise in the usual manner a wound thread, with which a gear meshes with

  motor pinion that slides them like an elastic rack.

  The training device is usually in the middle of the

  front ruler of the intermediate frame. Other details of the coaching

  of the roof roof are not shown in the figures, since the driving position of the roof does not intervene in the descrip-

of the invention.

  A guide channel 10, of which FIGS. 1, 3 and 14 to 16 represent the position and the embodiment, is fixed on each side and

  other mobile panel 3, parallel to its longitudinal sides.

  The slide 10 comprises two guide slots 11 and 12 which, from its closed position, allow in a known manner to open the movable panel 3 above the fixed flag 1, by lifting its rear edge as flaps. articulated ventilation, or to slide it under the fixed rear roof, after lowering its front edge. A guide pin 13 assigned to the rear slot 12 is

  to do this in solidarity with each of the rear pads 7 (Figure 3).

  An opening lever 14 is articulated on the guide pin 13 and guided by two other guide pins in the front slot 11 of the slide 10, the front pin extending to form a pusher 15.

  whose function will be described below.

  As shown in Figure 2, the front pads 6 are rigidly connected by a cross member 16. The profiled sheet forming the front pad 6 and visible in Figures 1 and 2 extends forwardly in a

  lower part 17 of hinge 19, which comprises a higher part

  The hinges 19 present on both sides of the movable panel 3 form an axis 20 perpendicular to the direction of sliding (Figure 4) and around which the movable panel 3 pivots. On each of the upper parts 18 of hinge bears the screw 21 of height adjustment of the movable panel, which engages in a threaded part 23, mounted on a stiffener 22 of the panel

mobile phone (figure 2.).

  A water baffle 24 is placed under the gap between the rear edge of the movable panel 3 closed and the rear edge of the cutout 4 of the roof, so that the water penetrating despite the seal 25 shown in points and dashes in Figure 4 on the folded rear edge of the movable panel, is directed to the lateral gutters of the intermediate frame 2, as shown in Figure 5. The water deflector 24 is guided by pads 27 (Figure 5) on the branches 28

  slide 5, which also guides the front and rear skates 6 and 7.

  A snap mechanism 26, the description of which is superfluous here,

  is fixed on the water baffle 24 and articulated at 29 on the guide slide 10. The ratchet mechanism 26 present on both sides of the sunroof drives the water baffle in the direction of sliding of the movable panel 3. The mechanism 26 further produces a separable latching with the corresponding slideway 5, so that the open movable panel does not slide simultaneously during opening or closing movements. Snapping is removed only when the trailing edge of the closed movable panel is lowered below the rear portion of the horn to initiate the sliding movement. Each guide slide 10 further carries a guide pin 30 (FIG. 1), which passes through a recess 31 of the guide branch 28 of the slideway 5, opposite which it is in the closed position of the movable panel, when from the aforementioned lowering of the rear edge of the latter, and is below the branch 28 during the subsequent sliding movements. When sliding the closure of the roof, the guide pin 30 prohibits the pivoting of the movable panel upwards as its rear edge is still below the rear part

flag.

  The lower part of the movable panel 3 is covered by a lining constituted by a lower portion 32 in the form of a plate

  and an upper portion 33, also plate-shaped and articulated

  As shown in particular in FIGS. 4 and 1, the lower part 32 of the lining comprises, at the rear, a ventilation cut-out 34, on a substantial part

  of its surface, and thus has the form of a frame. The lateral edges

  the lower part 32 of the lining are mounted behind the scenes.

  At the front, the lower part of the lining comprises, at two or more points on its upper face, resilient and crooked snap-fastening bosses 36 (FIG. 7), which are detachably snapped onto a beak 37 which is co-planar with the cross-member 16, The lining 32, 33 thus follows the sliding movements of the movable panel 3. The lower part 32 of the lining, however, does not participate in the pivoting movements of the movable panel, as illustrated by FIG. figure 4. Alone

  34. In order to avoid inadvertent vertical movements of the lower part 32 of the lining and as a result of slamming, the lower part 32 of the lining is applied by a boss 38 on the lower part of the crosspiece 16, as also shown in FIG. the

figure 4.

  The lower and articulated portions 32 of the lining, of which

  the lower surface is covered by a covering fabric, are solidified

  dared by spring blades 39 bandaged according to the direction of the

  opening movement. In the closed position and each posi-

  sliding of the movable panel 3, the pushers 15 are supported on ramps 40 of the hinged portion 33 of the lining and thus apply the latter flat on the lower part 32

  to close the ventilation cut-out 34. This position is

  in Figures 3, 14 and, in dots and dashes,

  beginning of the opening movement of the mobile panel, produced by the

  not shown, the pushers 15 move forward, so that the bandage of the spring blades 39 rotates the hinged portion 33 of the lining upwards, until the application

  on an elastic stop 41 fixed on the movable panel 3 (Figure 4).

  The arrow 42 in FIG. 4 indicates the direction of the ventilation pro-

  by the opening of the movable panel 3.

  In the case of rearward sliding of the roofing 32, 33 of the sunroof so far described, by eliminating the snaps between the projections 36 and the spouts 37, and the movable panel 3 being closed, the ramps 40 would be displaced towards the rear. rear, under the pushers 15 remaining fixed, so that the articulated portion 33

2 4 9 9 91 4

  should rotate upwards under the action of spring blades 39.

  It is obvious that the assembly and maintenance of the parts

  of the sunroof would be highly complicated. To avoid such annoying pivoting of the articulated portion 33 of the lining, the

  rear edge of the lower portion 32 forming frame carries a

  43, interacting automatically with the rear edge of the hinged portion 33, as described below. The production and operation of the locking element will be described later with reference to FIGS. 8 to 13. The locking element 43, whose width is small relative to its length (FIGS. 15 to 16), consists of by a base plate 44 and a wall, which is connected to both ends of the previous one in one piece, and thus delimits with the base plate 44 a cavity 46 extending over the entire width of the locking element 43. The wall 45 forms at the front end of the locking element 43 a boss 47 with front 48 and rear 49 facing faces. A fixing projection 50 is formed on the underside of the base plate 44. and slidably penetrates an oblong hole 51 on the rear side of the frame formed by the lower portion 32 of the lining. The

  oblong hole 51 limits the short distance of locking or unlocking

  on which the locking element 43 slides in parallel

  to the longitudinal axis of the car, like a slider.

  The locking element 43 is dimensioned so as to reach the water deflector 24 during relative sliding of the lining 32, 33 and the movable panel 3. In the relative position of the parts shown in FIG. is in its closed position of the cutout 4 of the roof, so that the pushers 15 push through the ramps 40 the articulated portion 33 of the lining in the position shown, as also shown in Figure 14. The front edge of the water deflector 24 is then applied to the docking face 49. When the packing 32, 33 slides backwards, that is to the right of the figure,

  from this position, the water deflector 24 remaining relatively

  The stationary mounting member slides the locking member until its fixing projection 50 abuts the front end of the slot 51. The base plate 44 then slides on the rear edge of the hinged portion 33 of the packing. , until the position shown in Figure 9 is reached. In this position, the articulated portion 33 is locked and can not pivot upwards when the pushers 15 no longer apply on the ramps 40. When the relative sliding of the packing 32, 33 continues beyond the small locking distance described, the wall of the lock elzeant 43 is deformed elastically downward under the action of the docking face 49, due to its small thickness and the cavity 46 which is under it . It is then possible to slide the locking element 43 under the face

  lower part of the water deflector 24. Figure 10 shows a position

  relative parts during this sliding phase.

  When the locking element 43 has slipped under the deflector

  24 as a result of continuing the relative sliding, the wall 45 returns elastically in the initial position according to FIG. 8, so that the locking of the rear edge of the articulated portion

  33 of the packing is maintained. The lining 32, 33 can then be

  smooth under the fixed rear portion of the roof, that is to the right of the figure, to completely clear the inner face of the movable panel 3. The hinged portion 33 of the lining remains in its locked position flat on the part lower 32. When the lining 32, 33 is brought forward, that is to say to the left at the end of assembly or maintenance operations, the docking face 48 front of the element of lock 43 reaches the edge

  back of the water deflector 24, before the full slide stroke

  The coupling is unlocked during sliding and pivoting thus first upwards, as far as the stop with the lower face of the water deflector 24. A further pivoting of the articulated portion 33 upwards is excluded. Before the articulated portion 33 can disengage from the water deflector 24 during the continuation of the relative sliding, as shown for example in Figure 13, the ramps 40 slide again under the pushers 15, so that the part 1 1

  articulated 33 is folded back into its fully closed position,

  8. In this position, the bosses 36 enclose

  again on the spout 37 of the cross-member 16, so that the

  packing 32, 33 is again fixed relative to the movable panel 3.

  As shown in FIG. 13, the locking element 43 passes during sliding forward under the water deflector 24, in

  a state of elastic deformation of its docking face 48.

  During the first mounting of the sunroof, the lining 32, 33 is simply inserted from the rear between the branches 35 and 28 of the slides 5, the locking element 43 being manually slid into the locking position shown in FIG. 9. After fixing on the intermediate frame of the functional parts with the inserted lining, which is first at the rear part, and after the mounting of the movable panel 3, the lining 32, 33 is slid into its final position shown in the figures 11 to 13. Figure 16 shows the position of the parts during the sliding

packing 32, 33 forwards.

  Instead of a single locking element 43, judiciously

  placed in the median longitudinal plane of the car, it is pos-

  sible to have several locking elements with

  valle on the rear edge of the frame formed by the lower portion 32 of the lining; it is for example possible to provide two lateral locking elements. The rear edge of the frame formed by the

  lower portion 32 of the lining and delimiting the ventilation cutout.

  34 at the back can be removed, so that the cutout 34

  is open at the back. The locking element 43 is easily molded

  by transfer of a suitable plastic material.

  To prohibit contact between the fabric covering the part

  32 of the lining and the rear part of the intermediate frame

  2, during the sliding of the lining 32, 33 towards the rear,

  the rear end of the lower part has at least one

  slip 52, protruding downward on the lower surface

  bottom of the packing (Figure 6). This boss slightly raises the lower portion 32 without reducing its guidance

lateral.

  The two parts 32, 33 of the lining can be produced in a light material with good dimensional stability, such as a double-walled plastic honeycomb plate, as shown at 53 in FIG. 14. The lining thus has a very low weight. and excellent dimensional stability, but it is also possible to form in a single operation all the bosses,

  protrusions and cuts during the molding of the plastics material.

  Of course, various modifications may be made by those skilled in the art to the principles and devices which have just been described as non-limiting examples, without

depart from the scope of the invention.
