Abstract

Actuator device for a pivotable closure member such as a window or a pivoting vehicle roof, comprises a crank articulated at one end on the closure member and whose other end is connected to a rotatable member secured to one end of a cable arranged to roll up on and unroll from at least a portion of said rotatable member. The other end of the cable is fixed to a motor, for example a linear actuator. The connection between the articulated crank and the rotatable member (3) is effected by a conical pinion (4) in mesh with a toothed sector (5) on the rotatable member (3). The axis of the conical pinion is orthogonal to the axis of rotation of the rotatable member (3). The motor means is mounted on a support (12) secured to the rotatable member (3).

Claims

1. Actuator device for a pivotable closure member such as a window or a pivoting vehicle roof of the type comprising a crank articulated at one end on said closure member and whose other end is connected to a rotatable member secured to one end of a cable arranged to roll up on and unroll from at least a portion of said rotatable member, the other end of said cable being fixed to a motor means, characterized in that the connection between the articulated crank and the rotatable member (3) is effected by means of a conical pinion (4) in mesh with a toothed sector (5) on said rotatable member (3), the axis of said conical pinion being substantially orthogonal to the axis of rotation of said rotatable member (3), the motor means being mounted on a support (12) secured to said rotatable member (3).

2. Actuator device according to claim 1, characterized in that said cable (1) is prolonged by a second cable (18) whose one end is carried by the rotatable member (3), said cables (1, 18) being disposed in such a way that traction on one or the other of the cables (1, 18) drives the rotatable member (3) in rotation in one direction or the other.

3. Actuator device according to claim 1, characterized in that the rotatable member (3) comprises radial projections (7a, 7b) for guiding the cable.

4. Actuator device according to claim 1,

characterized in that the assembly of the device, except the actuator (6), is disposed within a casing (9) constituted by two elements of complementary shape and juxtaposed on each other, the two elements being provided with projecting portions (8a, 8b, 8c) and recesses so as to form a guide conduit for the cable and to provide openings (19) for the passage of the cable to the exterior of the casing (9).

5. Actuator device according to claim 4, characterized in that at least one of the elements of the casing (9) comprises a projecting portion which is received within an axial opening of the rotatable member (3) to constitute the rotation axle of the rotatable member (3).

6. Actuator device according to claim 4, characterized in that the elements of the casing (9) are provided at one of their ends with a toothed sector (11) for prepositioning adapted to coact with complementary means carried by the support (12) of the actuator so as to permit a variation of angular position of the actuator (6) at the time of assembly.
