Abstract: A vehicle seat comprises a backrest mounted on a seat by means of a pivot mechanism comprising two flanges fixed respectively to the seat and the backrest and linked one to the other by means of a single-train hypocycloid gear mechanism which causes the backrest to pivot about an axis of rotation which in turn moves in circular translation about a fixed axis. The gear mechanism is driven by a control shaft which is centered on the axis of rotation on a level with said gear mechanism and which has a part forming a crank comprising an end centered on the fixed axis, which end is driven in rotation by an electric motor mounted on the seat part.

Abstract: A fixing device is proposed for mounting the slide bars of a seat on a vehicle floor by means of vertical anchoring pins fixed to the floor. These anchoring pins are located in holes provided in the base of the fixed section of the slide bars and then blocked bv sliding latches which are resiliently biased into their locked position. The latches are initially held unblocked by triggers and these triggers are moved back releasing the latches when the seat is positioned on the floor of the vehicle.

Abstract: It relates to a vehicle seat comprising a seat part which is mounted on the vehicle floor by means of a front connection including a catch. This catch is provided with a notch intended to engage with a first horizontal transverse spindle integral with the floor in order to pivot the seat rearwards around said first spindle and to bring it into a use position where the seat part extends substantially horizontally. A finger projects frontwards and comprises an upper face turned in the opposite direction to the opening of the notch and intended to abut against stop means in said use position, these stop means being integral with the floor.

Abstract: A removable automobile vehicle seat, comprising anchorings adapted to enable rapid mounting and dismantling of the seat on the bodywork of a vehicle. The seat comprises in addition an electrical circuit connected to an electrical supply connector which is connected to an electrical connector mounted on the vehicle bodywork, the connection and disconnection being made by the installing movement of the seat on the vehicle bodywork.

Abstract: A vehicle seat slide includes a fixed section, a mobile section, a memory shoe sliding along the fixed section and defining a memorized position of the mobile section, a first actuator which simultaneously unlocks the slide and fastens the shoe to the mobile section, and a second actuator which unlocks only the slide. The second actuator operates a fastener device of the shoe via a cable.

Abstract: A vehicle seat has a horizontal safety bar which restricts the displacement of the occupant in the event of an accident. This bar is moved towards the occupant by means of an activating device in the event of an accident, following a certain activation trajectory, after which the bar is displaced in the opposite direction applying deceleration on a dissipation trajectory, the initial portion of which follows the final portion of the activation trajectory.

Abstract: This concerns a vehicle seat including a back pivoting mounted on a seat part by means of a locking mechanism able to be activated by a user to unlock the seat back, the seat comprising additionally an inertia safety device adapted to drive the locking mechanism into its locked position in the event of the vehicle being subjected to an impact. This safety device includes an input component which is driven by the pivoting of the seat back and which is connected to the locking mechanism by means of an inertia clutch.

Abstract: A pivot mechanism comprising first and second frames linked so as to pivot, in which locking members may co-operate with teeth on one of the frames in order to lock the mechanism, and at least one stop member which is joined to the second frame and which is arranged so that the locking member abuts at an angle against said stop member if the pivot mechanism is subjected to a pivot torque in a first direction of rotation whilst the locking member is in its locked position: if this torque exceeds a threshold value, the stop member is displaced towards the over-locking member and pushes it against the teeth of the frame in order to lock it.

Abstract: A slide rail for a vehicle seat, comprising a fixed section, a mobile section, a memory retaining runner sliding along the fixed section and defining a memorized position of the mobile section, a runner catch, a first control to simultaneously unlock the slide rail and clip the runner to the mobile section, and a second control to only unlock the slide rail. The runner catch is brought resiliently to its unlocked position, and it is moved into its locked position by engagement with a cam surface integral with the mobile section, only when this mobile section leaves its memorized position or returns into said memorized position.

Abstract: A seat, the back of which is connected to the seat part by a pivot including two webs able to be fixed by toothed inserts controlled by a cam. In order to allow the folding down of the seat back forwards, then the replacing of this back into its initial position, the pivoting cam is connected to an external memorisation mechanism, which comprises a control part connected to this cam by a lost motion mechanical connection adapted so that the activation of the cam does not move the activating part, and so that the activation of the memorisation mechanism drives the movement of the cam to its unlocked position.

Abstract: This concerns a slide rail for a vehicle seat, comprising a fixed section, a mobile section sliding on the section, and a catch movable vertically between a locked position and an unlocked position allowing the mobile section to slide.

Abstract: This concerns a slide rail for a vehicle seat including a fixed section and a "U" shaped mobile section, a memorization runner sliding along the fixed section and defining a memorized position of the mobile section, a runner catch, a first control to simultaneously unlock the slide rail and attach the runner to the mobile section and a second control solely to unlock the slide rail. The memorization runner is brought resiliently to its locked position where it engages with notches provided on the flange of the fixed section. The runner slides on a single flange of the fixed section.

Abstract: A mobile joint mechanism comprising a fixed flange and a mobile flange that can be locked by two units controlled by a sliding push-rod that is itself activated by the pivoting of two control plates linked one to the other by idle movement, to free the mobile flange. A circular guide includes radial gaps that receive the units, and maintain the units in retracted position when they disengage from the radial gaps through the pivoting of one of the control plates, which also fixes the circular guide to the mobile flange. The mobile flange can thus turn freely before in re-locks at its original angle when the radial gaps of the circular guide return to be opposite the units.
