Abstract: The invention proposes an actuator for a component of a land motor vehicle, of the type including an actuator casing (12) which is produced by injection molding of thermoplastic polymer material and which delimits an internal volume in which are arranged: at least one electric motor (16), and an internal mechanical transmission (18) comprising at least a first gear wheel (24), which has an axis of rotation (A2) perpendicular to the axis of rotation (A1) of the drive shaft (20), characterized in that the first gear wheel (24) has a toothing (28), called axial toothing, which is formed of gear teeth having a bottom-top extension according to the direction of the axis of rotation (A2) of the first gear wheel (24), and which meshes with the output pinion (22) of the electric motor (16).

Abstract: An ignition unit for at least two sparkplugs of an internal combustion engine, the unit being in the form of a box having therein a reception cavity receiving an electronic printed circuit, a plurality of mutually separate housings extending side by side transversely relative to the reception cavity, a separating partition disposed between the reception cavity and the housings which defines a through opening between each of the housings and the reception cavity, and a plurality of ignition coils, each mounted in a corresponding one of the housings. Each ignition coil is fitted with a primary connector including 1) a fixing member for fixing the ignition coil to the box to enable the ignition coil to be mounted in a corresponding one of the housings, and 2) connection terminals between the ignition coil and the printed circuit.
