    Motorized swivel motion vehicle seat
    The present invention relates to vehicle seats with a pivoting movement of substantially vertical axis, that is to say comprising a pivoting functionality around an axis of rotation substantially perpendicular to the floor of the vehicle to which the seat is attached. question.
    In automobile type vehicles, it has already been proposed to be able to pivot a passenger seat to obtain a lounge type configuration, that is to say at least one seat oriented in a position other than forwards. It has also already been proposed to use a vertically pivoting movement to facilitate the entry and exit of passenger (s) in a vehicle when a conventional wide access by the door is not available.
    Furthermore, some have proposed a movement of a central vertical axis with a motorization as for example taught by the document US4846529. However, it turns out that a substantially centered axis of rotation has certain drawbacks vis-à-vis the immediate environment of the seat such as the door or the center console, with which there may be interference. In addition, safety requirements have increased, and some already known solutions prove to be insufficient with regard to mechanical strength in the event of an impact.
    It therefore appeared a need to offer a seat for a vehicle provided with a pivoting function with a vertical axis better suited to avoid mechanical interference with the environment and at the same time satisfying the handling requirements in the event of an impact.
    To this end, a seat for a vehicle is therefore proposed, comprising a pivoting function with a vertical axis, the seat comprising:
    - a base (1) configured to be connected to the floor (PL) of the vehicle via longitudinal slides,
    - a support frame (2) mounted for rotation on the base, by means of a pivot joint (JP) with an axis ZI and at least three curved slide links (G1, G2, G3),
    - a seat frame (4) connected to the support frame, directly or via a raising mechanism, and a motorization device (3) interposed between the base and the support frame and configured to cause a rotation movement of the support frame with respect to the base, and in which the axis ZI of the pivot joint is eccentric with respect to a central zone of the seat frame.
    Thanks to these provisions, the connection between the base and the support frame is hyperstatic and can withstand significant forces without deforming or becoming detached. In addition, the motorization allows a user of the seat a comfortable and effortless adjustment of the vertical orientation of the seat.
    In addition, the central space under the seat cushion remains available and free either for the feet of passengers behind or for storing objects.
    In this document, the term “curved slide connection” is understood to mean a mechanical guide interface along a predefined path which prevents translation of at least one degree of freedom (here the vertical direction) of one element relative to another. element. It is noted that the course is not necessarily rectilinear, here in this case it is a predefined course substantially in the form of an arc of a circle. Instead of "curved slide connection", the term "bilateral connection" could also be used.
    We also note that the rotation of the support frame is completely decoupled and independent of the longitudinal movement of the longitudinal slides connecting to the floor.
    In various embodiments of the invention, one can optionally have recourse to one and / or the other of the following provisions, taken individually or in combination.
    According to an option, the motorization device can comprise an electric actuator, or a pneumatic actuator or a hydraulic actuator. By "electric actuator" is meant an electromechanical actuator with a linear motion output. This represents a practical solution for implementing the motorization between the support frame and the base, by means of an articulated mounting at the respective ends of the cylinder body and of the movable / sliding operating rod.
    According to an option, the motorization device (3) preferably comprises a rack (5) and a geared motor (6) with an output pinion engaged with the rack to form together a pinion rack link, the geared motor being fixed to one elements chosen from the base (1) and the support frame (2), and the rack being fixed to the other of the elements chosen from the base and the support frame. This forms a well known, reliable and robust solution in the field of seat mechanisms.
    According to one option, the rack is preferably arched, with preferably a center of curvature substantially coinciding with the position ZI of the axis of the pivot joint. Thus the mounting of the gear motor can be very simple, that is to say direct fixing without crankshaft or take-up part.
    According to an option, the geared motor is preferably of the non-reversible type. This avoids having to use a specific system to brake or lock the current position.
    According to an option, the gear motor is preferably fixed to the support frame, and the rack is fixed to the base. The gear motor can be almost accommodated in the volume of the seat cushion without encroaching on the storage volumes on the floor and / or on the volume available for the feet of the rear passenger.
    According to an option, the pivot joint arranged in the vicinity of the left rear corner or of the right rear corner of the base and the motorization device is arranged in the vicinity of the opposite diagonal corner.
    Thus, the largest possible lever arm is used to obtain rotation with the reduced-size gear motor.
    We can offer the reception function when the rear corner 'inside' (opposite the door) is used for the pivot location; we can also offer the 'lounge' function, that is to say a rotation towards the interior space of the vehicle when the rear exterior corner (against the door) is used for the pivot. We can also offer a movement that combines both the inward orientation, i.e. the 'lounge' configuration, and the outward orientation, i.e. the 'reception' configuration. .
    According to an option, the pivot joint occupies a first corner of the base and the three curved slide links occupy the three other corners of the base respectively.
    This maximizes the stability of the assembly by a mechanical connection to each of the four corners of the base / of the support frame.
    According to an option, the gearmotor is mounted astride the rack, preferably with a roller (35) opposite the drive pinion (34), so that the rack is sandwiched between the output pinion of the gear motor and roller.
    Very robust solution, which makes it possible to take into account the industrial manufacturing dispersions of the rack and to overcome the positioning dispersions of the rack; this also authorizes a cantilever mounting of the rack.
    According to an option, one or more curved slide links are formed by an arcuate light (61,62,63) arranged in one of the elements chosen from the base (1) and the support frame (2), and a mushroom pin (71,72,73) complementary received in said lumen, and fixed to the other of the elements chosen from the base (1) and the support frame (2). The arched light has a banana (or bean) shape, and its two ends form natural stops to limit the stroke. The lights are obtained by stamping. This light system forms a simple and proven solution to ensure solid and efficient guidance.
    According to an option, each lumen (61,62,63) has a curvature such that its center of curvature is located near the axis ZI of the pivot joint.
    One thus obtains a rotation substantially without friction or jamming at the level of the slide connections, and one can avoid the plays potentially generating noises.
    According to another option, one or more curved slide connections are formed by a jaw (9) arranged in one of the elements chosen from the base (1) and the support frame (2), and an arched cheek (8) (one can also call it an arcuate rib or an arcuate blank) received in said jaw and fixed to the other of the elements chosen from the base (1) and the support frame (2).
    It is an alternative solution if the light solution is not optimal.
    According to an option, the rack is presented as a flat and thick arched rod, preferably with a cantilever mounting.
    Such a rack rod can be obtained in a thicker blank than the sheet forming the frame of the base or of the support frame.
    According to an option, the base (1) comprises a front crossmember (13), a left movable profile (11) and a right movable profile (12) and the rack is fixed to one of the movable profiles. Advantageously, the base is presented as a rigid and coherent structure.
    According to an option, which the base (1) preferably further comprises an auxiliary intermediate crossmember (14) comprising a motorized assembly for longitudinal adjustment, the base being preferably devoid of rear crossmember. This intermediate crossmember makes it possible to synchronously control the movement of the two mobile sections and also reinforces the consistency and the rigidity of the base.
    According to an option, the support frame (2) comprises two lateral beams and a central crosspiece (24) connecting the two lateral frame-support beams. Advantageously, the support frame is presented as a rigid and coherent structure.
    According to an option, the support frame does not have a rear crossmember. This preserves a very substantial available space for the occupant's feet located just behind the seat for storage spaces for objects.
    According to an option, the angular travel available, for the support frame relative to the base, is at least equal to 10 degrees and less than 50 degrees.
    According to an option, the available angular travel covers an angular sector situated on either side of a neutral position corresponding to the frontal direction, that is to say according to the direction of movement of the vehicle. We can thus combine the 'lounge' configuration and the 'reception' configuration as already mentioned above.
    Other aspects, aims and advantages of the invention will appear on reading the following description of an embodiment of the invention, given by way of non-limiting example. The invention will also be better understood with reference to the accompanying drawings in which:

    Door access (entrance and
    In the example illustrated, it is a simple rotation around an axis denoted Zl.
    In the illustrated configuration, the angular range available for rotation is less than 50 degrees.
    Such a limited angular travel allows the mechanical configuration which will be described later.
    In the following, the direction X corresponds to the longitudinal direction of the vehicle, the direction Y corresponds to the transverse direction of the vehicle, the direction Z corresponds to the vertical direction of the vehicle.
    General structure
    The seat 90 comprises a seat 41 and a backrest 42. The seat 90 is generally fixed relative to the floor of the vehicle PL. Starting from the floor, there are provided longitudinal rails 15 known per se, motorized or not. The slide on the left, of axis XI, comprises a fixed rail fixed to the floor and a movable profile 11 movable in the longitudinal direction; similarly, the straight slide, of axis X2, comprises a fixed rail fixed to the floor and a movable profile 12 movable in the longitudinal direction.
    The movable sections 11,12 are part of a structure here called base 1. The movable sections are connected by a front cross member 13. The front cross member 13 extends between the front ends of the movable sections 11,12, and is fixed d one part to the front end portion of the left movable profile 11 and the other part to the front end portion of the right movable profile 12.
    The movable sections 11, 12 as well as the front cross member 13 are made of thick stamped sheet metal as known in the field of structures of metallic seat frames.
    In the illustrated case of motorized longitudinal adjustment movement, there is provided a motorization assembly which forms an intermediate auxiliary cross member attached to the middle portion of the left movable profile and the other to the middle portion of the right movable profile
    12. Concerning the motorization assembly for the longitudinal translational movement, the support, the electric motor
    14M, flexible drive cables, and screw-nut connections are known and the reader can refer to the document
    FR2883810 by the same applicant.
    The base forms a coherent and rigid frame guided in longitudinal translation relative to the vehicle floor.
    Guiding in the longitudinal guides reinforces the rigidity and the solidity of
    The base (we note that there is no rear crossmember in the illustrated solution which will help to provide a practical space to accommodate the feet of a passenger of objects
    The rigid base secures the left movable rail 11 with the right movable rail 12 which move in translation together along the longitudinal direction, without relative movement of one relative to the other.
    The longitudinal translational movement is noted Ml.
    Above the base, there is provided a support frame 2 mounted for rotation about a vertical axis Zl. The support frame 2 is a metal frame formed by a left side member 21, a right side member 22, and two cross members 23, 24 which connect the two side members. The crosspieces 23, 24 are here tubular but could take any other form. The support frame is presented as a coherent and rigid structure slightly deformable under high stress.
    The support frame 2 is connected to the base by a kinematic function and a motorization function, provided by a motorization device 3.
    The motorization device 3 is functionally and mechanically interposed between the base 1 and the support frame 2; more precisely it rests on one of the two and acts on the other of the two.
    The motorization device 3 for the pivoting function is described below with a rack and pinion solution as illustrated in the figures. However, the present invention also encompasses any possible motorization means. We can choose in particular a motorization device based on an electric actuator, a pneumatic actuator, a hydraulic actuator. By “electric actuator”, it is necessary to understand an actuator with an outlet with linear movement (using for example a mechanism of screw-nut), assembled like an extensible telescopic rod. One can for example provide a hinged mounting at the respective ends of the cylinder body and the activation rod so as to allow the relative movements necessary for the rotation of the support frame relative to the base.
    The main body of the jack is fixed to one of the elements chosen from the base 1 and the support frame 2, and the movable rod of the jack is fixed to the other of the elements chosen from the base 1 and the support frame 2 .
    The seat 42 of the seat, seen from above, has a general shape of square or even rectangle. The frame 4 of the seat is supported on a square or even rectangular base corresponding to the seat but may be slightly smaller in size.
    A “central zone” ZC of the seat is defined as a zone generally centered on the intersection of the diagonals and which extends homothetically or not in the grip of the seat over an area substantially equal to a quarter of the horizontal surface bounded by the seat frame. Note that the central area could be round, polygon etc.
    The pivot axis of the seat ZI is eccentric relative to the middle of the seat, that is to say is found outside the central zone ZC.
    Typically the central zone ZC covers from 30% to 50% of the surface of the surface delimited by the two slides 15.
    As will be seen for the second embodiment, the invention is not limited to pivoting in one direction relative to the front alignment.
    Cinematic
    The vertical pivoting movement is denoted M2.
    For the kinematic function, a pivot joint JP with an axis ZI and a guide by three curved slide links G1, G2, G3 are provided.
    Referring to Figure 1, when the seat is in the frontal position, position denoted PI, the pivot angle Θ is zero (Θ = 0). When the seat swivels, the swivel angle increases (Θ> 0), position denoted P2. The seat (seat + backrest) pivots independently of the positions and longitudinal movements of the slides 15.
    We note that the axis noted X3 (reference for 0 = 0) is parallel to X and is concurrent with Zl.
    Each of the Gl — G3 curved slide links contributes to guiding in rotation about the axis.
    ZI by prohibiting movements according to the other degrees of freedom.
    In the example illustrated, the curved slide links are each formed by an arcuate lumen 61, 62, 63 arranged in one of the elements chosen from the base 1 and the support frame 2, and a mushroom pin
    71,72,73 complementary received in said lumen, and fixed to the other of the elements chosen from the base 1 and the support frame 2.
    Precisely, on the right side of the frame, the lights are formed in the support frame and the mushroom pins
    71.72 are set
    Conversely, in the right movable profile 12.
    at the front left corner of the frame, the light is formed in the base and the mushroom pin 73 is fixed to the support frame 2.
    The available angular travel is in
    The example illustrated by about degrees. It is understood that the system of guide rails based on lights is very advantageous for mechanical support but hardly allows, in the usual size of the seat frame, to offer an angular travel greater than 30 degrees, even degrees, even 50 degrees.
    Generally, depending on the configuration presented, the available angular travel will be between 12 ° and 50 °.
    In the example shown, the pivot joint
    JP of axis ZI is arranged in the vicinity of the rear left corner of the seat base 1, and the motorization device is arranged in the vicinity of the diagonally opposite corner (front
    It should be noted here that the axis ZI of the joint could be located as an alternative (not shown) pivot at a position distance from the rear left corner and from the rear right offset corner, by means of the presence of an axis support fixed on the base and extending towards
    inside of The area of the base (door-to-door mounting false).according to another conf iguration, well heard, the joint pivot JP axis ZI can to be arranged at neighborhood of the corner back right from base 1 and the device of motorization is arranged in the neighbourhood from the opposite corner in diagonal (before left).
    Note that the pivot joint occupies a first corner of the base and the three curved slide links respectively occupy the other three corners of the base. This makes it possible to distribute as widely as possible and in the most balanced manner the forces which may be undergone by the seat, in particular in the event of an impact undergone by the vehicle.
    By "bilateral" connection between the support frame and the base, it is understood that a force parallel to the axis of rotation and tending to move apart or bring these two parts together produces practically no relative displacement of the support frame relative to the 'base.
    Thus, each of the bilateral connections between the support frame and the base prevents separation by tearing off the seat relative to the base.
    Since the seat is connected to the base by the three bilateral links and by the pivot link, i.e. a total of four links, there is a hyperstatism between the support frame 2 and the base 1.
    Engines
    For the motorization function as illustrated in the figures, there is provided a rack 5 and a geared motor 6 with an output pinion 34 engaged with the rack 5 to form together a pinion-rack link.
    In the example illustrated, the gearmotor 6 is fixed to the support frame 2, and the rack 5 is fixed to the base 1.
    However, in an inverted alternative configuration, the word reducer 6 could be fixed to the base and the rack could be fixed to the support frame.
    According to an advantageous aspect, the geared motor 6 is of the non-reversible type. For example, it may include a worm gear transmission mechanism with a high reduction rate in which a torque exerted on the output member cannot turn the engine. In other words, a torque exerted by the motor rotates the output member, but even a large torque exerted on the output member cannot, in the opposite direction, cause the motor to rotate.
    Thanks to which, when the electric motor is not controlled, the reduction motor 6 acts as a powerful brake and consequently one can avoid having to add in parallel a locking mechanism to guarantee that the current position is preserved without intention of displacement. This is useful not only in static but also if the vehicle is moving (no rotation in the current position in the event of an accident).
    Other structural elements
    The vehicle seat usually includes a backrest tilt adjustment functionality, namely the backrest 42 can pivot around a transverse axis note Yl, this pivoting movement is noted
    M3.
    In addition to the longitudinal adjustment movement and the vertical pivoting, the seat may include a seat raising movement denoted M4, which in the illustrated case uses pivoting connecting rods denoted 46, as known per se, and therefore not particularly described in detail here. For this raising movement, one end of each connecting rod and fixed to the support frame 2.
    Thus, the seat frame 4 is either directly connected to the support frame 2 in the absence of a raising mechanism, or else is connected via said raising mechanism to the support frame 2.
    The seat frame 4 is generally included inside the seat 41 which also includes a mattress configured to receive the user.
    Rack and pinion
    The rack 5 is arcuate, preferably with a center of curvature substantially coinciding with the position ZI of the axis of the pivot joint JP.
    The rack is made of metallic material, preferably steel, by a stamping and cutting process, from a sidewall of thickness between 2 mm and 5 mm.
    The rack comprises a fastening end 51 intended to be mechanically connected to the base, a free opposite end 52, a long arcuate and smooth side 53 and a long opposite side provided with teeth 54.
    In the example illustrated, the rack is fixed to the straight movable profile 12, with a cantilever mounting from its fixing axis A, namely the opposite end 52 to the fixing is not attached at the base, it can turn slightly around the A axis.
    According to one example, the rack is fixed by a screw 50 which allows a certain flexibility in rotation about a vertical axis A of the screw.
    Thus, even if the curvature of the rack is not perfect relative to the center of rotation of the support frame, the docking of the pinion 34 will still be perfect with the flexibility of the fixing of the rack.
    In addition, the motorization device 3 is configured to sandwich the rack 5 between a retaining roller 35 and the drive pinion 34. The retaining roller can be mounted to rotate freely around the axis
    Z6, as well we limit them friction introduced through the device of motorization. Indeed, We dispose departure and other of the
    rack two similar flanges 31, 32 which contain bearing surfaces for receiving on the one hand the axis Z6 of a follower roller 35 and on the other hand the axis Z3 of the output pinion 34.
    There are sliding pads 70 interposed between each the head of the mushroom pins and each of the complementary slots.
    In FIG. 3, the sliding pads 70 have been shown schematically and symbolically in the space between the base and the support frame to illustrate the function of the slide links G1, G2, G3; in reality they are fixed either to the support frame or to the base according to the direction of assembly of the mushroom pin as will be seen below
    As illustrated in FIGS. 8 and 9, two possible and opposite configurations are illustrated, with regard to the arrangement of the lumen 61,62,63 of the slide connection and of the complementary mushroom pin 71,72,73.
    The mushroom pin 73 is fixed by means of a threaded connection 75 to the support frame 2, through the use of a hole 92 and a lock nut 91. A spacer 93 is provided between the base and the support frame. An interface socket 94 can also be provided for the correct positioning of the parts before screwing. The head of the mushroom pin 73 traps a jumper 95 of general square shape. The jumper 95 comes to bear on a sliding pad 70 fixed all around the lumen 63. The axis of the mushroom pin 73 is located at a distance R3 from the axis of the pivot joint ZI.
    Each of the mushroom pins (respectively 71,72) are fixed by means of a threaded connection on the movable profile 12 of the slide. A spacer 96 is provided between the top of the profile and the support frame.
    An interface socket 94 can also be provided for the correct positioning of the parts before screwing. The head of the mushroom counter holds a jumper 95 of general square shape. Which comes to bear on a sliding pad 70 fixed all around the light (respectively 61,62). The axis of the mushroom pin is located at a respective distance R1, R2 from the axis of the pivot joint.
    It is noted that the edge of the lights, being formed by stamping, has a curved record which minimizes the risk of the presence of burrs interfering with the relative path of the mushroom pin inside the light. It is noted that the interface sleeve can be formed as a Teflon part to promote sliding without substantial friction.
    Second embodiment
    According to a second embodiment shown in Figures 10 and 11, a variant for the guidance function is shown. In place of the lights and the mushroom pawns, jaws 9 are placed opposite the edges 8 in an arc. Each of the jaws extends on either side of the edge of the circle and thus forms a stop for any movement along the vertical axis. In other words, the jaw forms a groove in which the relatively mobile facing part is received.
    The jaw can be secured to the fixed base or secured to the rotating support frame.
    More precisely, with reference to FIG. 10, for the guide (sliding link) located diagonally of the pivot joint, the jaw 9 ′ is embedded on the support frame, and the edge in an arc is fixed to the base, then that conversely for the other two slide connections, the jaw 9 is fixed to the base and it is the edge in an arc 8 which moves with the support frame.
    As illustrated in FIG. 11, each of the jaws comprises a lower bearing 81 and an upper bearing parallel and spaced from the lower bearing by a distance slightly greater than the thickness of the edge in an arc of a circle 8.
    It is noted that the angular amplitude includes a first zone authorizing a displacement in the clockwise direction Θ2 from the front straight line direction, and a second zone authorizing a displacement in the counterclockwise direction 03 from the line direction frontal right.
    One can have for example an angular travel of + or - 25 °. The travel is not necessarily symmetrical with respect to the position Θ = 0.
    FIG. 10 illustrates another solution for the motorization function, it is a 3 ′ actuator, typically an electric actuator, although fluid-to-oil actuators are not excluded. The cylinder body is fixed for example to the base by means of a ball joint, and the cylinder action rod is fixed for example to the support frame also by means of a ball joint.
