  The present invention relates to a sunroof control with a rigid motor-driven roof, o a drive element which can be actuated forwards and backwards is supported on the rear edge of the roof and o a roof lifting mechanism in its closed position, consisting of transverse connecting rods and pivoting levers, is arranged on the roof in the area of its rear edge and controlled by

said drive element.

The object of the present invention is more particularly to improve a sunroof control of the type described above in order to reduce as much as possible the space necessary for its mounting and to ensure a safe and regular movement of the connecting rods driving the levers of the roof when this

  the latter is in a position coinciding with the opening of the roof.

To achieve this objective, the present invention proposes that a sus-

  crossed pension with two arms is inserted between on the one hand the element of

  drag that can be operated forward and backward and on the other hand

  connecting rods for the roof lifting mechanism, which are supported by being moved

  can be laid transversely in a guide groove provided at the rear end of the roof. The use of a two-arm cross suspension for

  the drive of the connecting rods actuating the levers of the roof presents the advantage

  tage on the one hand to require only an extremely reduced place for its assembly and on the other hand to guarantee a perfectly regular displacement of the rods from where, consequently, a regular lifting of the roof in its position

  closure aligned with the plane of the vehicle roof.

  According to a preferred embodiment of the invention, the suspension

  crossed with two arms is assembled to the drive element by means of

  diary of a stirrup-shaped connection element. As a transport bridge can possibly cooperate in the lifting movement of the roof in its closed position, it is provided according to the invention that the connecting element in the shape of a stirrup rests on the driving element while being able to oscillate around a horizontal axis, orthogonal to the direction of

movement of said drive element, respectively of the roof. The arti-

culation of the stirrup-shaped connecting element on the connecting element

  drag can be achieved through the front end in-

  rolled of said drive element, surrounding the transverse part of said

connecting element.

  According to another characteristic of the invention, the arms of the cross suspension bear on the connecting element in the form of a stirrup and on the connecting rods of the lifting mechanism of the roof, being

articulated around trunnions of axes inclined on the vertical. The-

  said pivot axes which are parallel, form with the vertical

  an identical angle, preferably an angle of about 300. The position in-

  cine of the trunnions of the arms of the cross suspension makes it possible to actuate the latter with very low friction, even when the roof is

in the raised position.

  Still according to the invention, it is provided that the middle zone of the arms

of the cross suspension is bent in the opposite direction upwards, respect-

  downwardly so that the ends of said arms move in a common plane. The arms of the cross suspension comprise at their ends rounded pads, projecting essentially on one side on said arms, that is to say offset laterally in the same direction by a certain distance from the longitudinal median plane of said arms, so that all the trunnions of the arms of the cross suspension are in a common plane perpendicular to the plane of movement of the roof and inclined about 300 vertically when the suspension

is completely closed.

In accordance with other details of embodiment of the invention, the

  connecting rods transversely displaceable and connected by their ends ex-

  to the roof lever, are connected to the suspension arms

crossed by ends bent orthogonally backward

  first, protruding from the rear edge of the roof, respectively from the deck

transport. The connecting rods are advantageously movable in the mete area

  diane of the pavilion, respectively of the transport bridge, thanks to

  plastic seats attached to the pavilion, respectively

transport bridge.

According to another embodiment of the invention, the arms of the cross suspension are connected to the connecting rods of the lifting mechanism of the

  pavilion by means of bent pieces, movable transversely-

  ment in slideways made of synthetic material, one of the branches of which protrudes from the rear edge of the roof, respectively from the transport bridge. The invention will be explained in a purely indicative way using

of the attached drawings by way of nonlimiting example.

  We will ultimately find a nomenclature of the different benchmarks used

during the description.

A rigid sunroof pavilion (1), shown only in part in the drawing, can be displaced longitudinally by means of pads, not shown, in guide rails (3) arranged on a sunroof frame (2). The roof (1) shown in the lowered position in Figure 3, can be slid under the rigid rear part of the vehicle roof (5) to clear an opening (4) of the roof. A guide groove (8) orthogonal to the direction of movement is provided at the rear end of the roof

  of the roof, in which are arranged connecting rods (9) movable or-

thogonally to the direction of movement of the pavilion, which operate, by

  through an outer coiled end (10) and through shafts

  dice (11) resting on the roof, levers (12) resting in the guide rails (3). The levers (12) make it possible to raise the roof (1) from its position corresponding exactly to the opening of the roof (4) in its closed position, aligned with the plane of the vehicle roof. The control of the sunroof also comprises a drive element (13) which can be actuated by motor back and forth; on the front end, located on the side of the roof, of said drive element (13) is

  articulated an element having seen from above the shape of a stirrup (14), mo-

  bile around an axis perpendicular to the direction of movement of the element

  drive ment (13). The articulation of the connection element (14) is carried out via the coiled end (16) of the drive element (13), surrounding the transverse part (15) of the connection element (14) in the shape of a stirrup. The arms (17), (18) of a crossed suspension resting, on the one hand, on the connecting element (14) and, on the other hand, on the connecting rods (9) being articulated around trunnions

  parallel axes (19), forming an angle of about 300 with the vertical.

  The connecting rods (9) are supported by being transversely displaceable in the middle zone of the guide groove (8) by means of slides (20) of suitable synthetic material, integral with said groove, and comprise

bent ends (21) projecting from the rear edge of the roof (1).

  The arms (17), (18) of the cross suspension are articulated by their end

  mite located on the side of the pavilion on the bent ends (21), said joints being inclined by about 300 vertically when the pavilion is in the closed position. To allow this position of the pins (19), the roof being in the closed position, it is provided that the bearings (22) of the pins (19) of the arms (17), (18) are in the same

  sense, offset by a certain distance from the median plane longitu-

  dinal of said arms. As shown more particularly in FIG. 4, the pivot axes (19) of the arms (17), (18) of the cross suspension are

formed by rivets (23).

According to the embodiment presented in Figures 7 and 8, a transport bridge (80) supported by pads (7) in the guide rails (3) is assembled to the roof by means of connection elements fixed (6). Inside the transport bridge are arranged connecting rods (9) movable perpendicular to the direction of movement of the roof, which control, by means of an outer coiled end (10) and bent shafts (11) arranged on the roof, levers (12) resting in the guide rails (3), said levers (12) making it possible to raise

  the flag of its position coinciding with the opening of the roof in its po-

  closing position aligned with the plane of the vehicle roof. The sunroof control also includes a drive element (13)

  can be actuated by motor forward and backward, consisting of a seg-

  flat material. On the front end, located on the side of the roof, of the drive element (13) is articulated a shaped connection element

stirrup (14). The connecting rods (9) are supported by being transversely displaceable -

ment on the central area of the transport bridge (80) by means of slides (20) of suitable synthetic material, fixed on said transport bridge, and have bent ends (21) projecting from the edge

rear of the pavilion.
