Abstract: The fixed flange with an inner toothing and the mobile flange with an inner toothing cooperate with a double satellite mounted in a ball bearing forming inside a housing for a composite cam. A sufficient excentration is provided between the diameter of the toothings of the double satellite and the intermediate part concentrical to the toothings of the fixed and mobile flanges so as to allow the composite cam made of two symmetrical and identical parts normally separated from one another at their upper portion by a spring which is slightly under tension and at their lower portion by a finger rigidly connected to an intermediate circular part mounted in bearing in the mobile and fixed flanges.

Abstract: A setting in position identification potentiometer is connected to terminals of the motor. The motor is supplied with a voltage (U.sub.feed) possibly variable and switchable between two reverse polarity states according to rotation direction. The potentiometer has a slider which is connected via a first dividing bridge to input of an analog-digital converter subjected to a reference voltage (U.sub.ref) connected to same possibly variable voltage via a second dividing bridge. Output of the analog-digital converter is connected to an electronic module. The resistor value at the ground of each of the two dividing bridges is respectively equal to a product of the other resistor value by a same multiplying coefficient A.

Abstract: The device comprises at least one rod normally locked by notched rollers mounted on pins and cooperating with at least one V-shaped bearing plate having toothed ramps, and the vertical displacement of which is made by rotation of a cam driven by a set of studs rigid with a circular member, with control means being further provided to drive this circular member.

Abstract: An electrocarrier cable has conductor elements and support or carrier elements. The conductors are lapped on insulating cores and are enclosed in fluorinated sheaths to form conductor elements which are stranded to an elongated central core, preferably with interleaved support elements. A braid of relatively inextensible fibers, i.e., aramide fibers, encloses the conductor elements and is coated with a polyurethane sheath. The cable is arranged such that the aramide fibers fail in tension before the conductors fail, and is particularly useful in a self-supporting cable for carrying low level currents, such as in the field of oceanography.

Abstract: Backlash free articulation reducing mechanism, usable notably for the setting of the various portions of an automobile vehicle seat, characterized in that each satellite has a central axis with a cylindrical (inner or outer) bearing surface intended for centering itself and reacting on a complementary cylindrical bearing surface (respectively outer or inner) provided on a star-shaped satellite-holder having due to its material and design, a sufficient resiliency for constantly applying the toothings of the satellites in the toothing of their respective flange, thereby allowing taking up clearances inherent to manufacture of this type of mechanism and allowing also absorbing without deterioration any overload able for example to appear during use of the reducing mechanism as an articulation of an automobile vehicle seat.

Abstract: The articulation mechanisms is made particularly of irreversible satellite mechanisms connected to one another by a connection bar. The connection bar has, on one of its portion, a member with toothings subjected to action of a spring which, when the connection bar is in position between two cams of the articulation mechanisms, causes a rotation of these cams and of the satellites related thereto for taking up the manufacturing and mounting clearances.

Abstract: Each fixation member is mounted on a mechanism for setting inclination of the seat back and is formed of a casing so shaped to receive a dagger fixed to each lower end of the seat back armature. The dagger is held within the casing by being wedged with assistance of a part made of a central serrated roller and two lateral smooth extensions of smaller diameters enabling the roller to rotate freely inside openings formed in the casing and to be pushed by at least one spring for wedging the roller between the dagger and said casing.

Abstract: A device for compensating for clearances between a satellite and toothings of flanges of a reducing mechanism provided for adjusting the position of a seat. The mechanism has a fixed flange and a mobile flange that are held against one another via a crimped ring and enclose an eccentrically mounted satellite that bears on a cam driven by a shaft. This shaft has a square section with a first conical portion, and with a cone that is disposed in a central opening of the fixed flange. A spring is disposed between the cone and a peg provided on the shaft. When a hard point is met upon cooperation of toothings of the fixed and mobile flanges with a double toothing of the satellite, a slight longitudinal offset movement of the shaft in either direction is produced, resulting via one of the first conical portion and the cone in a change in eccentration of the satellite, thereby providing for passage of the hard point.

Abstract: In the shaped junction portion, each end of the seat and back frame is deformed in order to obtain a flattened portion in a central area conveniently stiffened by thickened areas, raised edges, or protruding outer lips providing thereby for a perfect application of the shaped end of the tube onto a face of a flange of the articulation mechanism, these parts being thereafter connected together, junction studs of each flange of the articulation inclination being used for a respective centering of the part.

Abstract: The lower profile element is substantially of a U-shaped section and includes wings having each a median zone with a semi-cylindrical channel prolongated by a bent-over portion provided for covering V-bent vertical ends of side branches of the upper profile element. A wing of the lower profile element is cut out in order to form a row of teeth having each a trapezoidal shape prolongated by a rectangular shape in order to cooperate with an L-section latch-comb formed with rectangular openings and freely mounted on a pin which is displacable by a control of the slide. A spring applies to the latch-comb a pressure permitting a passage of teeth of the latch-comb through openings formed in the upper profile element so as to cause a penetration of the latch-comb into the openings between the row of teeth of the lower profile element for latching the upper profile element on the lower profile element.

Abstract: The safety slide comprises a lower fixed profile and an upper mobile profile. The lower fixed profile is of a U-shaped section and is formed with vertical wings horizontally bent for forming a lower rolling path and an upper guiding path in order to cooperate with balls. Rollers are placed between the vertical wings of the lower fixed profile and bent wings formed on the upper mobile profile with stiffening longitudinal corrugations, and are guided by vertical wings of the mobile upper profile.

Abstract: Each front seat has under the base plate in its median longitudinal axis a rack connector rod and a mechanical bolt, this rack connector rod cooperating with a box joined to the floor of the vehicle via a framing and a brace, this box containing a blockable motor device. The entire afore-mentioned unit cooperates with two parallel arms first of all joined to the rear part of the seat and secondly joined to the floor of the vehicle via a spindle containing a memory constituted by a ring with a notch and the nose of the lever.

Abstract: The reversible endless screw slides are fixed by their lower fixed elements to the vehicle floor via a base plate. The base plate is mounted under at least one of the two slides and carries a profile section forming a rack cooperating with a reversible endless screw and which can be locked by a second shoe. The movement of the second shoe is controlled by a lever able to pivot against action of springs via another lever fast with an articulated control bow placed between the two slides so as to free the endless screw placed in a casing and cooperating with the rack for forming a mechanical memory for the slides.

Abstract: A device for increasing the resistance and durability of an articulation mechanism, usable to control the position of a seat, includes a fixed flange rigidly connected with the seat and a movable flange rigidly connected with the movable part of the seat; these two flanges are rotatable with respect to each other by a mechanical assembly with a locking by suitable mechanism. The fixed flange carries, close to its periphery, a fine toothing that is not normally in contact with a fine continuous circular toothing provided on a peripheral circular element of the movable flange, these fine continuous circular toothings coming in contact with each other along a given length when the articulation mechanism is distorted as a consequence of a sudden shock.

Abstract: The planet wheel has either toothings having different diameters but a same tooth module or toothings of a same diameter but different tooth modules. The toothings are produced by die stamping of a disc down to a certain depth which provides, in the median plane of the disc, a central cheek against which bear the toothings thereby stiffening each tooth for preventing it from being crushed and deformed.

Abstract: The device comprises longitudinal adjustment slides for the seat. Each of the slides has a mobile element with an upper face carrying L-shaped supports with vertical wing portions. The vertical wing portion carries at least one mechanism having a control shaft for driving a rocking lever in rotation having a front end which cooperates with an intermediate part rigidly connected to a side portion of a framework of the seat. The rear end of the rocking lever cooperates with a front portion of a second rocking lever which is articulated on the vertical wing portion and has a rear portion which is mounted in a rear portion of the framework of the seat.
