The abutment device 28, visible in FIGS. 2 and 3, comprises an abutment 50 and an assembly 52 for fixing the abutment 50 to the rail 20.

The abutment 50 is, for example, made of rubber. The abutment 50 is in the form of a rectangular parallelepiped, and has, on its lateral face intended to be oriented towards the door 12, a protuberance 54 for damping the door, visible in FIG. 3. The fixing assembly 52 comprises a first flange 56, a second flange 58, a spacer 60 arranged between the first flange 56 and the second flange 58, and means 62 for guiding the first 56 and second 58 flanges between a spaced apart position and a close position of the flanges. The first flange 56 is intended to bear against the inner face 34 of the front wing 33, and the second flange 58 is intended to bear against the outer face 35 of the front wing, the front wing 33 being pinced between the first flange 56 and the second flange 58 in the close position of the flanges, as shown in Figure 2. According to the invention, the spacer 60 bears against the edge 36 of the front wing when the flanges 56, 58 are in close position. The guide means 62 comprise, for example, a screw 64 - nut 66, the passage between a spaced position and a close position of the flanges 56, 58 being obtained by clamping the screw 64 - nut 66. The nut 66 has two flats 67 for locking in rotation of the nut, the flats 67 being diametrically opposed. The first flange 56 has a bearing surface 68 against the inner face 34 of the front wing, a hole 70 for the passage of the rod of the screw 64, and a rib 72 for engaging in a complementary groove 74 of the second flange 58. The first flange 56 also has a recess 75 for receiving the flats 67 for the rotational locking of the nut 66. The bearing surface 68 and the rib 72 are disposed on the same face of the first flange 56 , and the recess 75 is arranged on the face opposite to said face of the first flange. The bearing surface 68 of the first flange is substantially planar. The second flange 58 has in its upper part a complementary shape of the outer face 35 of the front wing. The second flange 58 has a first bearing surface 76 against the outer face 35 of the upper portion 40 and the intermediate portion 42 of the front wing and a second bearing surface 78 against the outer face 35 of the lower portion. 44 of the front wing. The first bearing surface 76 has a curved shape corresponding to the elbow 45 connecting the upper portion 40 and the intermediate portion 42 of the front wing. The second bearing surface 78 is substantially flat.

The second flange 58 also comprises an orifice 80 for passage of the rod of the screw 64, a cavity 81 for receiving the spacer 60, and the groove 74 for receiving the rib 72 of the first flange 56. receiving 81 has a flange 82 bearing against the spacer 60. The first flange 56 and the second flange 58 are, for example, made of steel. Alternatively, the flanges 56, 58 are made of aluminum or stainless steel. The spacer 60, visible in FIGS. 3 and 4, is in the form of a rectangular parallelepiped and comprises an orifice 83 for the passage of the rod of the screw 64. The spacer 60 also comprises, according to the invention, a surface of support 84 coming into contact with the edge 36 of the rail, by pressing the flange 82 against the side of the spacer opposite the bearing surface 84, when the flanges 56, 58 are in the close position. The spacer 60 is, for example, made of steel. Alternatively, the spacer 60 is made of aluminum or stainless steel. The first flange 56, the second flange 58 and the spacer 60 are, for example, made of the same material.

The bearing surface 84 has a concave shape, and has two projections 86. The projections 86 are arranged at two opposite ends of said bearing surface 84, and are intended to bear against two distinct zones of the edge 36, said areas being longitudinally spaced from each other. Thus, when fixing the abutment device 28 to the guide rail 20, the user begins by orienting the protrusion 54 of the abutment in the direction of the door 12, the abutment device 28 can be fixed indifferently to the left end or at the right end of the guide rail 20. The user tightens the screw 64 - nut 66 to bring the flanges 56, 58 closer to each other, the nut 66 being locked in rotation around the axis of the screw 64 by engagement of the flats 67 in the recess 75 of the first flange. The tightening of the screw 64 - nut 66 assembly is performed until contact, on the one hand, between the bearing surface 68 of the first flange and the inner face 34 of the front wing, and secondly between the bearing surfaces 76, 78 of the second flange and the outer face 35 of the front wing.

In the close position of the flanges 56, 58, the spacer 60 furthermore, according to the invention, bears against the edge 36 of the front wing, and thus ensures a better tightening of the fixing assembly 52 on the front wing 33. The bearing surface 84 of the spacer further has a concave shape thus providing a bracing of the spacer 60 on the edge 36 of the rail in the close position of the flanges 56, 58. Indeed, the Support flange 82 of the second flange then comes into contact with the side of the spacer opposite the bearing surface 84, so as to exert pressure of the bearing surface 84 towards the edge 36 of the rail. In addition, during the first impact of the door 12 against the stop 50, the projection 86 opposite to the damping protuberance 54 penetrates the material of the edge 36 and further improves the clamping of the fixing assembly 52 on the wing 20. The fixing assembly according to the invention also makes it possible to easily position the stop 50 at the desired location of the rail 20 in the longitudinal direction X, since the attachment of the stop 50 to the rail 20 is ensured by clamping. . It is thus conceivable that the fixing assembly according to the invention makes it possible to better maintain the adjustment of the abutment with respect to the rail over time, while allowing an adequate positioning of the abutment along the rail.
