  • Patent number: 5064246
    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.

  • Patent number: 4950088
    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.

  • Patent number: 4896398
    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.

  • Patent number: 4895038
    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.

  • Patent number: 4787593
    Abstract: The device enables a trim adjustment of the vehicle seat. An upper side of each upper section of a slide member carries two square members having vertical wings. The vertical wings maintain, at their upper ends either frontwardly or rearwardly of the seat, spindles on which is articulated a shoe-square. One of the two square members carries an articulation iron fitting enabling, by means of a reduction lever rotating with the mobile flange of each articulation, to raise a rear or front shoe-square in order that a seat frame fixed on the shoe-squares is displaceable by a clearance angle delimited according to needs either for a rear part of the seat or for a front part of the seat between a lower dead point and an upper dead point.

  • Patent number: 4770464
    Abstract: The articulation member comprises asymetrically guided bearing plates. A fixed flange is shaped in order to support, by means of sectors, sliding bearing plates having an upper toothing pitch corresponding to pitch of a toothing of a movable flange. The bearing plates are normally pushed back from the toothing by elastic means and have positions which are angularly shifted for two of them and submitted to bias of control means such as a cam. An angular shift of two of the bearing plates is of 120.degree.-.alpha./3 (=240.degree.-2/3.alpha.) with for complement 120.degree.+2/3.alpha., .alpha.being an angle forming a pitch for each tooth of the toothed ring and teeth of the bearing plates.
