Motor vehicle headlight having a reflector of complex surface shape with modified intermediate zones

Abstract: A motor vehicle headlight of the type comprising a lamp having a filament (100), a reflector (200) defining an optical axis (Ox), and a closure glass (300), the filament emitting light freely in all radial directions thereabout and the reflector having a smooth and essentially continuous reflecting surface which reflects the rays emitted by the filament in such a manner as to cause the majority of them to be situated beneath a cut-off (hHc; hh) constituted by two half-planes of given height and slope. According to the invention the reflecting surface comprises a central zone (201i-206a; 210) which reflects rays from the filament so that they propagate in planes which are essentially vertical, two intermediate zones (201m, 203m, 205m; 202m, 204m, 206m; 220, 230) situated on either side of the central zone and connected thereto with continuity, which intermediate zones reflect the light rays from the filament by imparting a substantial deflection thereto in planes essentially parallel to the cut-off half-plane with the rays participating in defining the cut-off, and at least one peripheral zone (201e, 203e, 205e; 202e, 204e, 206e; 240, 250) situated beyond one or both intermediate zones and being connected thereto with continuity, the peripheral zone(s) reflecting the rays from the filament so that they propagate in planes which are essentially vertical and parallel to the optical axis.

Primary optical element, lighting module and headlamp for a motor vehicle

Abstract: A primary optical element for a motor vehicle lighting module, comprising a single monoblock input member and a corrective part, the input member having at least one input face intended to receive light, the input member being connected at output to the corrective part. The corrective part comprises a light output face, at least partly in the shape of a substantially spherical dome, the input member and the corrective part forming a monoblock structure, wherein a vertical profile of the input face of the input member has a convex first part and a second part that is planar or concave.

Electronically openable lock fitting for a motor vehicle

Abstract: The invention relates to an electronically openable lock fitting for a motor vehicle, connected to main electric supply means (3) and emergency electronic supply means for the lock in the event of a malfunction of said main means. The emergency supply means comprise a power reserve component (6) and electric energy reserve means (6), and an identification element (4, 8D) ensuring the identification of the user. The identification element comprises at least one signal receiver (4) communicating with an element which can deliver a signal in order to identify the user. According to the invention, connection of said power reserve means (9) is controlled in such a way that the power reserve means (9) supply the energy reserve component (6) once identification has been made and authorized.

Steering lock for a motor vehicle steering column

Abstract: An antitheft device is provided for locking a motor vehicle steering column against rotation. The steering column includes a gear wheel which is fixed coaxially to the steering column shaft, and a pinion with an axis parallel to the steering column axis. The pinion is mounted for rotation in a moveable pinion support which is displaceable between a disengaged position, in which the pinion is disengaged from the gear wheel, and an engaged position in which the pinion is in mesh with the gear wheel. The steering lock also includes a clutch for preventing rotation of the pinion about its axis on the pinion support below a specific torque.

Device for mixing an air stream and apparatus for heating and/or air-conditioning the cabin of a motor vehicle comprising this device

Abstract: The mixing device, for distributing in variable proportions a main air stream ( 8 ) flowing through an apparatus for heating and/or air-conditioning the cabin of a motor vehicle between a hot air duct ( 14 ) and a cold air duct ( 18 ), comprises a perforated panel ( 40 ) arranged in the hot duct ( 14 ) and a shut-off plate ( 44 ) that can move between an open position in which it is spaced away from the perforations ( 42 ) in the panel ( 40 ) and a shut-off position in which it shuts off the panel, a shutter ( 50 ) for adjusting the passage cross section of the cold air duct ( 18 ) that can move between an open position and a shut-off position, a control mechanism ( 54 ) for controlling, in synchronism, the movement of the shut-off plate ( 44 ) and the movement of the shutter ( 50 )
