1. A lock-up clutch (12) for a hydrokinetic coupling device (10), for automobile vehicles, comprising: a main axis (X-X);at least one first element (44, 46) mounted around the main axis (X-X) and having a first friction surface (S1);a second element (14A, 36) mounted around the main axis (X-X) and h
1. A lock-up clutch (12) for a hydrokinetic coupling device (10), for automobile vehicles, comprising: a main axis (X-X);at least one first element (44, 46) mounted around the main axis (X-X) and having a first friction surface (S1);a second element (14A, 36) mounted around the main axis (X-X) and having a second friction surface (S2), the first friction surface (S1) intended to cooperate selectively with the second friction surface (S2) of the second element (14A, 36);an adjacent element (14A, 36) mounted around the main axis (X-X); andarticulation means (50) and sealing means (56) both disposed axially between a proximal bearing face (52) of the first element (44, 46) and a distal bearing face (54) of the adjacent element (14A, 36);the first element (44, 46) and the adjacent element (14A, 36) extend radially, orthogonally to the main axis (X-X) and rotationally connected by connecting means (60) adapted to transmit torque between the first and adjacent elements (44,46, 14A, 36);the rotational connecting means including a plurality of elastic tongues (60) extending radially between the first element (44, 46) and the adjacent element (14A, 36), and at least one first junction portion joined to the first element (44, 46) and one second junction portion joined to the adjacent element (14A, 36);the tongues (60) being adapted to be deformed elastically in the axial direction to allow movement of the first element (44, 46) relative to the adjacent element (14A, 36) about the articulation means (50). 2. The lock-up clutch according to claim 1, wherein the articulation means (50) are formed by an annular boss that projects axially relative to one of the following faces: either the proximal bearing face (52) of the first element (44, 46) or the distal bearing face (54) of the adjacent element (14A, 36) and a top portion of which cooperates with the other of the above faces: either the axially facing distal bearing face (54) of the adjacent element (14A, 36) or the proximal bearing face (52) of the first element (44, 46). 3. The lock-up clutch according to claim 2, wherein the sealing means (56) are formed by the articulation means (50) operative between the first element (44, 46) and the adjacent element (14A, 36). 4. The lock-up clutch according to claim 1, wherein the sealing means (56) are elastically deformable at least in the axial direction so that said sealing means (56) form progressive action means. 5. The lock-up clutch according to claim 1, wherein each elastic tongue (60) extends circumferentially between its ends (61, 63) along a rectilinear or curvilinear profile. 6. The lock-up clutch according to claim 1, wherein the elastic tongues (60) exert an axial elastic return force to ensure permanent contact between the articulation means (50) carried by one of the following elements: the first element (44, 46) or the adjacent element (14A, 36), and the bearing face (52, 54) of the other of the above elements: the first element (44, 46) or the adjacent element (14A, 36). 7. The lock-up clutch according claim 1, wherein the elastic tongues (60) are separate from the first and adjacent elements (44, 46) that they connect rotationally; and wherein one end (61) of the ends (61, 63) of each tongue (60) forms the first junction portion fastened to the first element (44, 46) via first fixing means (62) and the other end (63) of the ends (61, 63) forms the second junction portion fastened to the adjacent element (14A, 36) via second fixing means (64). 8. The lock-up clutch according to claim 1, wherein the elastic tongues (60) are in one piece with the first element (44, 46) or with the adjacent element (14A, 36) to which each one-piece tongue (60) is joined by at least one junction portion. 9. The lock-up clutch according to claim 1, wherein the elastic tongues (60) are curved. 10. The lock-up clutch according to claim 1, wherein the first element is formed by a support disk (44) and/or a friction facing (46); and wherein the adjacent element rotationally connected to the first element (44, 46) is formed by a piston (36) or by a front shell (14A) of the casing (14) of the device (10). 11. The lock-up clutch according to claim 1, wherein the first element is in the form of a support disk and a friction facing attached to a radial front face of the support disk so that a front face of the friction facing forms the first friction surface.
