Abstract: A contactor carriage fitted so as to move translationally in an electrical switch of a motor vehicle, in a unit providing controls under the steering wheel, in order to establish according to a user command, an electrical contact for one or more predefined positions of the path of the carriage is disclosed. The carriage has at least one electrical contacting emplacement, a first housing for accommodating a high-current contactor element and a second housing for accommodating a low-current contactor element. An electrical contact is established at said emplacement either by placing a high-current contactor element in the associated housing or by placing a low-current contactor element in said housing.

Abstract: One end of the strap forming the safety belt is rigidly connected to a rear lower portion of the armature of the seating portion of the seat by a blockage mechanism. A shoulder keeper situated frontwardly with respect to the upper portion of the front face of the seat back provides for a sliding and guiding of a run of the safety belt passing above the passenger shoulder. An other end of the run of the safety belt is secured to an iron fitting fixed with one of the side flanges of the seating portion armature and forming a second fixation point. A keeper cooperating with a lock forms a third lower fixation point of the safety belt and is connected to the side flange opposite the second fixation point on the armature of the seating portion of the seat.
