Abstract

THE PRESENT INVENTION CONCERNS A DEVICE FOR SUSPENSION OF AN EXTERNAL SLIDING DOOR FOR A VEHICLE. THIS DEVICE INCLUDES AN EXTERNAL RAIL 2 MOUNTED ON THE BODYWORK 1 OF A VEHICLE. IT IS CHARACTERIZED IN THAT THE B TRUNK OF THE RAIL 2 IS PLACED BETWEEN THE END TRUNCON C, AND THE RIGHT FRONT PART 10 A OF THE OUTER RAIL 2 FORM AN ACUTE ANGLE WITH THE SLIDING DIRECTION OF THE DOOR.

  SLIDING DOOR SUSPENSION DEVICE FOR VEHICLE

  The present invention relates to a suspension device of an outer sliding door for a vehicle, comprising an outer rail provided with an end section whose end is bent in the opposite direction to the closing direction of the door, and a wheeled carriage for supporting and guiding the door carried by this outer rail. A suspension device for an outer sliding door is already known, in which the outer rail is curved about 1800 in the vicinity of the frame of the gate.

  of the gate to slide to a certain degree towards the

  opening of the door; however, it is essential, with this

  tif, exerting a certain pressure opposite to the direction defined by the end of the curved rail relative to the direction of movement of the door, such that the door leaf can reach its closed position This arrangement avoids the shapes particularly the roundings of the portal frame, without hindering the

  complete closure of the gate, which is a considerable advantage

  ble for its manufacture and installation.

  It is also known to bend the end section of the rail

  450 to facilitate the opening of the door, including the

  penetration of the door leaf in the opening of this door.

  This realization, however, requires a particular shaping of the

  frame of the gate, so that this frame does not hinder the movement of the

so many doors.

  For this purpose, the present invention proposes to make a device

  door suspension, which allows one hand to slide easily

  this door inside its own opening, and on the other hand to avoid any complex construction in order to facilitate the last

phase of the closing operation.

  For this purpose, the device according to the invention is characterized in that the rail section, disposed between the end portion and the portion

  right up to the front end of the parallel outer rail

  the to the vehicle body, forms an acute angle with the direction

sliding door.

  By this means, the prolonged overlap of the right rail, in the end zone opposite to the section of rail curved in the direction opposite to the direction of the closing of the door, makes it possible to avoid a significant braking of the kinetic force stored by the door during its closure,

  in such a way that the door reaches its fully closed position.

  without the assistance of an external thrust. In other words, thanks to the addition of this end section curved in the direction opposite to the direction of the closure, particular constructions of the

door frame.

  Additionally, the arrangement at an acute angle of this rail section causes the rollers of the wheeled carriage to adopt a position such that they prevent an overall displacement parallel to the rail.

  bodywork of the vehicle, which makes it possible to lock

tomatic sliding door.

  The present invention will be better understood with reference to the description

  of an exemplary embodiment and the appended drawing, in which

  As shown in FIG. 1, a vehicle body 1 comprises an outer rail 2. This outer rail 2 carries, as shown in FIG. 2, a carrier roller 3 rotating about an axis fixed on a sliding arm 6 known per se. having for example a profile in UA the end of the pivoting arm 37 are mounted the guide rollers 4, as well as the rollers of

  The outer rail 2 is substantially parallel to the body 1 The straight section of the outer rail bears the reference a; its anterior end is designated by the reference 10 At the front end of the right outer rail 2 is connected an end section designated by the reference b, which makes an acute angle with the direction of movement

  stored by the door at the time of closing is not

closure.

  In the closed position, the rollers 4 are in the position shown in solid lines in FIG. 1, and the guide rollers 5

  engaged in the end section 11 In this position, a

  overall placement of the guide rollers 4 and 5, parallel to the car-

  vehicle, is impossible, so that the door is
