DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a device having manual control keys, in particular to a device of the type for controlling at least one actuator device in a vehicle, particularly for electric window winders and/or electric door locks and/or electric rear view mirrors, in which a DC electric motor is driven to actuate the displacement of an associated actuation member.
BACKGROUND ART
As is known, currently for the control and drive of such actuator devices conveniently fitted on vehicles, and in particular motor vehicles, use is made in practice of a wiring system having wires dedicated to supplying electricity to the motor, which wires lead from a common central control unit for various actuator devices which include relay units, limiter circuits etc. This wiring system involves various disadvantages of a general character such as: the complexity and difficulty of fitting bundles of cables, the large number of electrical connections, the difficulty of identification of breakdowns, and the complexity of tests for operation of the installation during and/or after assembly to the vehicle, and in particular involve disadvantages for the control key device in that the full power current flows through them.
DISCLOSURE OF INVENTION
The object of the present invention is that of providing a manual control key device for controlling at least one actuator device, particularly in a motor vehicle, which can be produced and assembled very simply and with a high level of functional reliability, suited to a drive and control system which overcomes the above-indicated disadvantages, in particular a system of the type described in Italian Patent application entitled "A Control System for a Plurality of Electrical Devices in a Vehicle" filed on the same date.
According to the present invention there is provided a manual key control device for controlling at least one actuator device, comprising means operable to determine at least one electrical signal in dependence on the operation of at least one of the said keys, characterised by the fact that it includes a specific electronic processing unit for processing the said electrical signal for the said actuator device.
BRIEF DESCRIPTION OF DRAWINGS
For a better understanding of the present invention a particular embodiment thereof will now be described, purely by way of non-limitative example, with reference to the attached drawings, in which:
FIG. 1 is a view from above of a manual key control device formed according to the principles of the present invention; and
FIGS. 2 and 3 are respective sectional views taken on the lines II--II and III--III of the key device of FIG. 1.
BEST MODE FOR CARRYING OUT THE INVENTION
With reference to Figures from 1 to 3, the reference numeral 301 generally indicates a manually controlled key device which comprises, in a substantially known way, a main frame 302 in the form of a shaped container with a substantially square section, conveniently made of plastics material, having a central portion 380 which defines an internal space 381 by two pairs of parallel vertical, respectively orthogonal walls 304 and 308; in the internal face of the two facing parallel vertical walls 304 are formed two horizontal grooves 303 which serve as housings for lateral edge zones of a printed circuit board 305 which is thus disposed horizontally in the main plane of the frame 302.
From the upper region of this frame 302 extend two facing parallel vertical walls 304' at a relative distance less than that between the walls 304, and between these walls 304', in the middle zone thereof, there is a horizontal square section portion 307 the relative dimensions of the side of which are greater than the thickness of the walls 304' so that between this horizontal portion 307 and the associated vertical walls 308 of the frame 302, perpendicular to the walls 304 and 304', there are two spaces 309 in which are housed respective manually operable rocker type keys 310. These keys 310 have an upper portion 312 with an undulating surface and are of s
