FR2792027A1 - Car door mounting for cars with several rows of seats which allows it to slide when fully open comprises rack system to control pivoting and rocker to prevent sliding until fully open - Google Patents

Abstract

The mounting for a door (28) on a car allows it to pivot from the closed to the fully open position and to slide from the fully open position to a position clear of the opening. It comprises a mounting rod (48) which is fixed at one end to the car structure (40) and at the other (49) to the door. A rack (56) engages with a pinion (54) at the car end and a plate (88) with a toothed section at the door end to control the pivoting of the door. A rocker (102) prevents the door from sliding until it has reached the fully open position.

Description

"Hinge device for a swinging vehicle door

  automobile "The present invention relates to a device for articulating an opening leaf on the structure of a motor vehicle, which is pivotally mounted relative to this structure between an extreme angular position of closure and an extreme angular position of opening, and which is slidably mounted between its extreme open position and a

extreme clear position.

  o0 The invention relates more particularly to a hinge device for a side door of a motor vehicle for completely clearing a side opening, large longitudinal dimensions, allowing access to vehicle seats belonging in particular to two rows

seats.

  The corresponding door is also of large longitudinal dimensions and it is necessary that the articulation device allows the opening to be completely released without the opening, during the pivoting operation, encroaching too much laterally with respect to

  to the vehicle, while allowing its easy maneuvering.

  To this end, an articulation device has already been proposed by means of at least one articulation connecting rod, a first end of which is articulated on the structure around a first vertical axis of articulation and the second end of which of articulation is articulated on the opening around a second vertical axis of articulation, and of the type in which the opening is slidably mounted relative to the second end of the connecting rod in a horizontal direction of sliding substantially parallel to the plane opening general. An example of such an articulation device is described and shown in document FR-A-2,455,523. In this document, the sliding movement of the opening is controlled by the pivoting movement of the opening relative to the second end of the connecting rod and it therefore does not make it possible to render the two pivoting and sliding movements.

  successive and independent of each other.

  The object of the invention is to propose an improvement

  ment to such a type of articulation device which makes it possible to remedy the drawbacks which have just been mentioned while presenting great maneuverability for the users. To this end, the invention proposes an articulation device characterized in that it comprises: - means for controlling the pivoting movement of the opening, relative to the second end of the connecting rod, to the pivoting movement from the first end of the connecting rod relative to the structure; and - controlled blocking means which block the opening as long as it is not in its extreme angular position of opening and which release it by sliding at the end of the stroke.

  pivot angle of the sash.

  According to other characteristics of the invention - the controlled locking means comprise a member for locking the sliding means of the door which are controlled as a function of the angular position of the door around the second vertical axis of articulation; The blocking member is a rocker pivotally mounted about a vertical axis, a front control branch of which cooperates with a cam profile linked in rotation to the second end of the connecting rod and a rear blocking branch of which is capable of cooperating with a longitudinal door stop; the free end of each of the arms of the rocker carries a roller mounted to rotate about an axis parallel to the axis of rotation of the rocker; - The device comprises an intermediate plate which is slidably mounted longitudinally relative to the side door and which is pivotable, around the second vertical axis of articulation, relative to the second end of the connecting rod; - The intermediate plate carries at least one roller, in particular three rollers, mounted rotating around a horizontal axis and which is received in a fixed longitudinal rail carried by the inner side face of the side door;

  - the longitudinal stop belongs to the guide rail.

  Other characteristics and advantages of the invention

  will appear on reading the detailed description which follows

  for the understanding of which reference will be made to the appended drawings in which: - Figure 1 is a side view of the rear part of a motor vehicle comprising a rear side door fitted with an articulation device in accordance with the teachings of the invention, the door being shown in its extreme angular closed position; Figure 2 is a view similar to that of Figure 1 in which the rear side door is illustrated in its extreme angular position of opening; - Figure 3 is a view similar to that of Figures 1 and 2 in which the rear side door is illustrated in its extreme position released by sliding backwards; - Figure 4 is a side elevation view of the main elements for the pivoting and sliding mounting of the door relative to the vehicle body - Figure 5 is a detail view on a larger scale in section along line 5-5 of Figure 4; - Figure 6 is a sectional view along line 6-6 of Figure 4 of the main components of the hinge device according to the invention in the relative position they occupy when the door is in its extreme angular closed position ; - Figure 7 is a view similar to that of Figure 6 in which the door is shown in its extreme angular position 0io opening; - Figure 8 is a detail view on a larger scale of Figure 6; - Figure 9 is a sectional view along line 9-9 of Figure 8; and - Figure 10 is a view similar to that of Figure 8 in which the components are shown in the relative position they occupy when the door is in its position

extreme opening angle.

  There is shown, in particular in Figures I to 3, a motor vehicle 10 whose rear part 12 has a lateral opening 14, here on the left side of the vehicle, allowing access to seats 16 and 18 belonging to two rows of seats which here are a row

  intermediate seats 16 and a rear row of seats 18.

  In a known manner, the opening 14 is delimited vertically by an upper upright 20 and by a horizontal lower upright 22, while it is delimited longitudinally by a front upright 24 which is here a middle leg and by a rear upright 26 which is a rear foot of the

  vehicle body structure.

  The opening 14 is closed by a side door 28 of dimensions complementary to those of the opening 14 which is generally in the form of a generally vertical orientation panel having at its upper part a window 30 and which is delimited by an external side face

  32 and by an inner side face 34 (see Figures 6 and 7).

  The door 28 is mounted to swing, that is to say pivoting and sliding relative to the body of the vehicle thanks to the mechanism 36 which is particularly shown in

Figures 1 to 5.

  The mechanism 36 comprises a vertical tube 38 which is rotatably mounted around a first vertical axis of articulation A1, relative to the rear leg 26, by means of two upper 40 and lower 42 brackets which receive two rotations.

  pivots 44 and 46 linked in rotation to the tube 38.

  The upper and lower ends of the tube 38 are each connected in rotation respectively to a horizontal upper link 48 and to a horizontal lower link.

  which extend parallel in the same vertical plane.

  Considering the door in the closed position (FIG. 1) of the door, the rear longitudinal end 52 of the upper link 48 is linked in rotation to a toothed pinion 54 of axis A1 which meshes with a longitudinal rack 56 carried

  by the upper link 48 and which can move along

  in relation to the connecting rod 48 on which it is guided

  by a rear roller 58 and by a front roller 60.

  The upper rod 48 is thus called the driving rod, relative to the lower rod 50, insofar as it

  carries the rack 56 whose role will be explained later.

  On its inner face 34, the main panel of the side door 28 is equipped with three fixed sliding rails which are parallel and horizontal and among which there is a top rail 62, a bottom rail 64 and a rail

intermediate 66.

  Each rail 62, 64, 66 receives in roll a roller 68,, 72 which is mounted rotating around a horizontal axis carried by an intermediate plate 74 in the form of a V-shaped lying, as

  this can be seen in particular in FIGS. 1 to 4.

  The plate 74 is a rigid part comprising two generally horizontal upper 76 and lower 78 branches, each of which carries a roller 68, 70 in rotation and which are bent to join in an intermediate branch

  vertical 80 which rotatably carries the roller 72.

  The plate 74 with its rollers 68, 70 and 72 can thus slide longitudinally and horizontally relative to the

door 28.

  Furthermore, the plate 74 is pivotally mounted relative to the front longitudinal ends of the upper 48 and lower 50 rods around a second vertical axis.

of articulation A2.

  To this end, the front longitudinal end 49 of the upper link 48 carries a vertical articulation rod 84 around which the upper branch 76 of the plate 74 is pivotally mounted, while the front longitudinal end 51 of the lower link 50 carries an articulation rod 86 around which the branch 78 of the plate 74 is pivotally mounted, thus defining the second vertical axis A2

  of articulation of the device according to the invention.

  The plate 74, and therefore the side door 28, is thus mounted generally pivoting about the second vertical axis of articulation A2 relative to the longitudinal ends

  before 49, 51 of the two articulation connecting rods 48 and 50.

  As can be seen in particular in FIGS. 6 to 8, the branch 76 of the plate 74 carries, in a fixed manner, a toothed sector 88, of axis A2, which is intended to cooperate with the teeth of the longitudinal rack 56 so , according to an arrangement known for example from document FR-A-2. 717.143, to control the pivoting or rotational movement of the side door 28 around the axis A2 relative to the front longitudinal end 49 of the upper link 48, to the pivoting movement of the rear longitudinal end 52 of the upper rod 48 with respect to the fixed structure 26,, 54. This control is visible if one compares the positions illustrated in FIGS. 6 and 7 and is designed in such a way that, during the simultaneous pivoting movement around the two vertical axes A1 and A2, the side door 28 remains generally parallel to itself, that is to say that it extends permanently in a vertical plane

longitudinal orientation.

  1 5 As can be seen in particular in FIGS. 8 and 9, the horizontal upper branch 76 of the plate 74 comprises two parallel plates 90 and 92 between which the articulation rod 84 is mounted in a yoke inside a sleeve 94 welded to the front longitudinal end 49 of the

upper link 48.

  The lower horizontal plate 90 is extended transversely outwards towards the rail 62 by a tab 96 which extends inside the rail and which carries a

  rod 98 of articulation of vertical axis A3 parallel to axis A2.

  The rod 98 rotates a stop and guide roller 100 and it also rotates a V-shaped rocker 102 having two branches, substantially 90, front 104 and rear 106 each of which rotates at its free end 108 , 110 a roller 112, 114, these two rollers being thus mounted for rotation about parallel vertical axes

to the A3 axis.

  The rocker 102 is equipped with a return spring 116 which permanently biases it in rotation about the axis A3

  clockwise considering figure 8.

  Under the action of this return spring 116, the roller 112 cooperates permanently with the peripheral surface of cylindrical contour 118 of the front longitudinal end 49 of the upper rod 48 which also includes a notch 120 in which the roller 112 can be received, as it will be

explained later.

  o To allow the angular deflections of the rocker 102 around its axis A3, the vertical wall

  inside 122 of rail 62 has a window 124.

  Similarly, the vertical plate 126 which interconnects the plates 90 and 92 of the branch 76 of the plate 74

i5 has a window 128.

  The roller 100 permanently received inside the rail 62

  is likely to cooperate with a stop 130 formed in vis-

opposite inside the rail 62.

  The wall 122 of the rail 62 also includes a stop 132 formed in favor of the window 128 and with which the roller 114 carried by the branch is capable of cooperating.

rear 106 of rocker 102.

  The rocker 102, in cooperation with the other components, constitutes a switching device whose operation will now be described in detail and which allows the longitudinal sliding of the side door 28 to be authorized only when it has reached its angular position of full opening, and which moreover prevents any pivoting movement of the side door 28 when the latter is in

  sliding movement and / or in a clear rear position.

  As can be seen in Figures 8 and 9, as long as the side door 28, and therefore the plate 74, is in its extreme angular position of closure or as long as it has not reached its extreme angular position of opening illustrated in FIGS. 7 and 10, the roller 112 is in abutment against the cylindrical surface 118 and the rocker 102 cannot pivot under the action of the spring 116, the roller 114 thus remaining in a position

  angular opposite the stop 132.

  As long as the rocker 102 and the roller 114 are in

  this position, it is impossible to slide longitudinally-

  Lely the door 28, and the rail 62 from front to back, that is to say

  1o from left to right considering the figures.

  On the other hand, when the door reaches its extreme angular position of opening illustrated in FIGS. 7 and 10, the roller 112 can penetrate into the notch 120 of the profile 118 and thus allow a pivoting of the rocker 102 around the axis A3 in

  i5 clockwise to the position illustrated in figure 10.

  In this position, the roller 114 has entered the rail

  62 and it therefore no longer extends opposite the stop 132.

  The rail 62 is then free to slide longitudinally relative to the plate 74 and it is therefore possible to slide the side door 28 from the left to the right to make it pass from the position illustrated in FIG. 2 to the position

illustrated in figure 3.

  The extreme longitudinal position, that is to say the rear position released from the side door 28 illustrated in FIG. 3, is determined by stop means not

shown in the figures.

  When closing the door, starting from the rear position released in FIG. 3, the side door 28 is slid from right to left until the stop 130 comes into contact with the roller 100, the rocker 102 being always locked in rotation during this sliding movement towards the front due to its roller 112 which is received

in notch 120.

  When one reaches the stop position illustrated in FIG. 10 and if one continues to exert a force on the door 28 with a view to closing it, this force causes the start of the simultaneous rotational movement around the vertical axes A1 and A2 of the plate 74 and of the connecting rods 48 and 50, this rotary movement making it possible to completely close the side door 28 by causing, at the start of the 0o rotation stroke of the end 49 of the connecting rod 48 relative to the plate 74, 76,

  the release of the roller 112 from the notch 120.
