C. THE INVENTION CONCERNS A WIND DEFLECTOR DEVICE FOR A MOTOR VEHICLE ROOF, ARTICULATED ON THE COVER RAIL.

Description

1.- "Wind deflector device for a vehicle roof

  articulated on the overlay rail. "

  The invention relates to a wind deflector device for a roof of a motor vehicle comprising a

  roof opening which is likely to be closed by a

  sliding circle and which is surrounded, at least in its anterior zone, by a frame constituting a channel of water flow and which is provided with an elevated inner wing delimiting this channel towards the opening of the roof, and on which is placed a cover rail, with a wind deflector disposed along the front edge of the opening of the roof and pivotable about an axis placed transversely to the longitudinal axis of the vehicle, the deflector

  with a body capable of pivoting towards the ex-

  when opening the sliding roof and

  ble to be folded when closing the sliding roof

  depending on the displacement of the lid.

  In a known wind deflector device of this type (DE-OS 21 38 162) the body of the wind deflector is hingedly connected to bearing supports, placed in the water flow channel and fixed thereto. by means of

  cover rails. This device certainly leads to a

  relatively simple, but it is still relatively

come expensive.

  The object of the present invention is to create a wind deflector device which reconciles an easy assembly.

  with a particularly low manufacturing expense.

  This object is achieved according to the invention in that the body of the wind deflector is articulated on the rail

recovery.

  This construction saves additional bearing supports. The cover rail can

  be easily secured without the need for

  gole of flow of rainwater in its parts channeling water. According to another form of the invention, a wing

  extending in practice horizontally from the overlay rail

  is screwed to the upper surface of the inner wing,

  dressed as a bead, the frame. The screw holes are then above the parts channeling the water of the rainwater channel and do not require

  this fact, no seal. In addition, they are easily

accessible for assembly.

  The body of the wind deflector can in principle

  be made of any material. In a particular way

  advantageously, it is made of a plastic material

  reinforced glass fiber, which is designated in

  tick under the name SCM (sheet molded compound). Such a material combines a high mechanical strength with a weight

  reduced even when the body of the wind deflector, to

  put favorable flow conditions, must present

  ter a relatively large thickness.

  To simplify the assembly even more, it is

  to provide that bearing locations for axes

  hinges are formed on the body of the wind deflector.

  For the folding of the body of the wind deflector it can

  at least one pivoting arm connected to the body of the deflec-

  wind through a drive mechanism.

  whose part belonging to the body of the wind deflector is preferably formed at the same time on the body of the

wind deflector.

3.-

  A particularly robust layout is ob-

  held when pivot bearing locations are also formed on the cover rail and the hinge pins cooperate with the pivot bearing locations of the wind deflector body and the cover rail.

  We contribute to a compact construction of the

  positive wind deflector when a torsion spring is placed on at least one of the axes of hinges, this torsion spring bearing on the one hand, on the body of the wind deflector, and, secondly, on the rail covering, and urging the body of the wind deflector in the direction of a

swing outward.

  An embodiment of the invention will be

  described in more detail below with reference to the drawings below.

  In the roof 10 of a motor vehicle, there is provided a roof opening 11 which can be closed by a cover

  rigid sliding vane 12. The roof opening 11 is

  turned on the front and laterally by a frame 13 which

  side rails 14 extending in a longitudinal direction

  of the vehicle, rails in which the sliding roof 12 is guided in known manner by means of skids, of which

  an anterior pad 15 is only shown in FIG.

  In the vicinity of the front edge of the roof opening 11, a wind deflector 16 is mounted so as to be able to oscillate about an axis placed transversely with respect to the longitudinal axis of the vehicle. The wind deflector is equipped

  of a deflector body 17 are made of plastic material

  forced by glass fibers, preferably a poly-

  glass-fiber reinforced ester, which has a form of

  favorable cross-section from the point of view of

  than flow (Figures 5, 6 and 7). On both sides of the body 17 of the wind deflector, are respectively formed two bearing locations 22, 23 in the form of

  bearing rings with through-hole openings

  24. Two other bearing locations thus formed 25,

  26 with through bearing openings 27, are

  wind in the middle zone of the body 17 of the wind deflector.

  As support for the wind deflector 16, there is provided a cover rail 30 of substantially L-shaped cross section with a flange 31 extending

  practice horizontally and with a wing 32 placed in

  tick vertically. The cover rail 30 applies

  by its wing 31 on the upper face of an inner wing suré

  lift 33, in the form of a flange, of the frame 13, this flange delimiting in the direction of the opening of the roof

  11, a water flow channel 34 formed by the frame 13.

  5. Screws 35 serve to connect the cover rail 30 to

  the inner wing 33 of the frame 13, these screws being threaded through

  to the orifices 36 of the cover rail 30. On this cover rail 30, advantageously made of metal, there are formed, for example by rolling, bearing locations 37, 38 in the region of the bearing locations 22, 23, as well as bearing locations 39, 40 in the

  zone of the bearing locations 25, 26 of the deflection body 17

  wind. Through the bearing locations 22, 23 and 25, 26 are threaded pins 41 or 42 in the form of pins which cooperate with the bearing locations 37, 38 or 39, 40 of the cover rail 30, and whose axes 41 serve as hinge pins. At the ends of the shafts 41, 42 are formed heads 43 or 44 to prevent lateral sliding of the shafts out of the bearing locations. Between the bearing locations 32, 33 a torsion spring 45 is placed on the hinge axis 41, this spring being supported by

  its projecting ends (46, 47) on the body 17 of the deflec-

  The torsion spring 45 tends to lift the deflector outwardly.

  16, that is to say to bring it into the position

  2. The wing 32 of the cover rail 30 encroaches on the side, facing the roof opening, of

the inner wing 33 of the frame 13.

  Appendices 49 are formed on both sides of the body 17 of the wind deflector, only one of these appendages

  being shown in the figures. Appendix 49 is

  swung a slot maneuver 50 in the form of buttonhole, in

  which engages a drive pin 51 to the ex-

  front end of a swivel arm 52. This swivel arm 52

  is connected at the other end to frame 13 through

  of a bearing support 53 and a pivot bearing

  54. The drive stud 51 may be made of rubber or other sound-absorbing material, and / or

  the maneuvering slot 50 may be provided with an elastic coating

  6.- soft tick (not shown) at least in the area where the drive stud 51 is applied when the deflector of

  wind is raised, this to avoid rattling noises.

  When the sliding cover 12 is open (FIG. 2), the wind deflector 16 is raised under control.

  torsion springs 45. When the cover is

  smoothing 12 is pushed forward in its iron position.

  meture, a cam 56, which is connected with a support of

  skates 57 or with another component that accompanies

  the sliding movement of the cover 12 is displaced on the pivoting arm 52. The pivoting arm 52 pivots counterclockwise about the

  pivot bearing 54. The driving stud 51 is disengaged

  place forward in the maneuvering slot 50. The deflec-

Wind meter 16 is folded down.
