Abstract
An electromechanical arrangement for automatic return of an electronic blinker located on a steering column of a motor vehicle includes a movable arm carrying a magnet at its free end and slaved at its other end by the intermediary of a roller to the rotation of the steering column of the motor vehicle. Reed ampulses disposed in fixed positions permit detection of predetermined values of angles of rotation of the steering column.
Claims9
An electromechanical arrangement for automatic return of an electronic directional indicator placed on a steering column of a motor vehicle, which comprises:
- a housing supported on the steering column;
- electrical contacts on the housing for connection to an electrical circuit;
- a movable arm carried by the housing and having means at one end thereof in engagement with the steering column for imparting rotation to the arm when the steering column is rotated;
- electrical switch means in the housing positioned so as to be adjacent an opposite end of the movable arm when the movable arm is rotated in one direction or another in response to rotation of the steering column and contacting said electrical contacts;
- stop means at a predetermined angle on each side of a plane of symmetry of said housing, fixedly connected to the housing at the same angular and radial distance on either side of the plane of symmetry, for stopping the arm in predetermined juxtaposed relationship with the switch means;
- means carried by the arm at said opposite end thereof for operating the switch means in response to predetermined, juxtaposed relationship therewith, and free of mechanical interconnection therebetween, whereby operation of the switch means results in automatic return of a directional signal indicator connected in the electrical circuit;
- wherein said means for operating the switch means comprises a magnet, and said switch means comprises flexible-strip switches in glass bulbs;
- and
- wherein said switch means are in a plane parallel to that in which said movable arm travels in the course of its rotation and are situated so as to be farthest apart at their ends nearest the steering column, with an acute angle being formed between their longitudinal directions.

- a sleeve surrounding said steering column, and a mounting strap of a cable-crimping type which passes through lateral openings formed in the housing wherein said housing comprises two essentially identical bodies;
- and
- a shaft upon which said movable arm is mounted for supporting at least one roller at end portions of a roller and thruster means which constantly push said end portions of said roller towards said steering column which are disposed inside each of said identical bodies constituting said housing.
