Definitions

  • the invention relates to a method and a belt retraction system buckle safety seat belt of the vehicle intervening during the folding of a vehicle seat for its retraction.
  • the invention belongs to the field of folding seats equipped today, like all seats, seat belts.
  • These foldable seats of first or second rank in the case of coupes or sedans, have the advantage respectively to facilitate access to the rear seats or to be able to offer a larger volume to the trunk of the vehicle.
  • Patent document JPH 0295953 discloses a loop strand retraction by the slaving of the position of this loop strand to the movement of the backrest, thanks to an articulated arm fixed on one side to the loop strand and the other side on the seat back. This arm can bend and lengthen thanks to a sliding system. Thus, this arm allows the buckle strand, when the seat back is folded down, to lower and to lodge in a space next to the seat and, when the back is raised, to stand automatically via the arms.
  • the patent document FR 2882981 discloses another retraction system of the buckle strand by servocontrolling the position of this loop strand to the movement of the backrest using a thin cable connecting these parts and passing through a pulley. When the seat back is lowered, the loop strand retracts by gravity, and when it is raised, the end cable raises the loop strand.
  • the invention has as its main purpose the establishment of a loop strand retraction compatible with a seat extraction without tools. To do this, the invention provides for passing the seat loop strand from a constrained operational position to a retracted position decoupling the seat in the extraction position.
  • the present invention more specifically relates to a strand loop retraction method mounted on a support via an arm in transverse rotation and for receiving in the position of use a seat seat belt, in particular of a motor vehicle seat, which method comprises equipping the support with a restoring force which is exerted on the loop strand arm from a retracted row position of the loop strand to its position of use, and to equip the seat with a position control mechanism of the loop strand, articulated transversely to bring the loop strand in antagonism with the restoring force from one of said positions to the other.
  • the articulation between the position control mechanism and the loop strand arm is formed around a movable connecting axis so that, in the stowed position, the seat is extractable by direct decoupling between the position control mechanism and the loop arm buckle.
  • a releasable locking of the arm of the loop strand can be actuated in the use position in order to neutralize the restoring force, which makes it possible not to add additional stress to the seat belt in the position of use;
  • the movable connecting axis is integral with the loop strand arm and the position control mechanism rotates about a fixed axis.
  • the invention also relates to a vehicle belt seat belt buckle retraction system
  • a support on which is mounted the loop loop in rotation via an arm about a mechanical axis transverse to the support, and a seat frame disposed laterally to the seat and intended to control the folding kinematics of this seat.
  • the seat frame is equipped with a substantially flat lateral position control part, rotatably mounted transversely about an axis and articulated with the loop strand arm around a movable transverse connecting finger, adapted to drive said arm between:
  • a position of use in which the loop strand is able to receive a closing end of the safety belt, defined by a position of the armature in which the position control part is able to drive the loop strand in this position of use under stress of an elastic return means mounted on the transverse mechanical axis; and - A storage position, wherein the loop strand is retracted under stress of the resilient biasing means and wherein the seat can be extracted by direct decoupling between the position control part and the loop strand arm.
  • the position control part is chosen between a cam, a hook and a slide
  • the mounting of the transverse connection finger is selected between secured to the loop strand arm, secured to the position control part, and rotated on the mechanical axis;
  • the finger moves along a concave rim of the cam
  • the return means is chosen between a coil spring, an elastic blade and an elastic seal.
  • the invention also relates to a motor vehicle comprising at least one seat equipped with a belt retraction system buckle buckle defined above.
  • the qualifiers "lateral” and “transverse” relate to the position of a seat in a conventional position of use oriented in the longitudinal direction of the vehicle, a “lateral” element extending vertically in standard mode of use - integrating the longitudinal direction of the vehicle - and the “transverse” direction being perpendicular to the longitudinal direction (or the lateral plane).
  • “towards the rear” and “towards the front” of a vehicle refer to directions directed towards the rear or front parts of the vehicle according to a conventionally accepted meaning.
  • the qualifiers “horizontal” and “vertical” refer to positions of elements with reference to the ground and in accordance with the direction of earth gravitation.
  • FIG. 5 is a partial perspective view of the motor vehicle seat equipped with the retraction system according to the preceding figures during the extraction of the seat, after separation between the position control cam and the arm of the loop b.
  • a seat 1 of a motor vehicle equipped with a retraction system 2 loop strand 3 is illustrated in the use position.
  • This retraction system comprises a suitable seat frame 4 and a support 5 of the loop strand 3 in particular releasable coupling.
  • the seat 1 is composed of a backrest 1 1, slightly inclined towards the rear of the vehicle relative to a vertical position, and a seat 12, also slightly inclined backwards. of the vehicle with respect to a horizontal position.
  • Seat frame 4 controls kinematics of this seat 1 between a position of use, illustrated by Figures 1a and 1b, and a folded position, illustrated by Figures 4a and 4b.
  • the armature 4 extends laterally along the seat 1 according to two articulated structures at the junction of the seat 1 1 and the backrest 12: a movable structure 4a integral with the backrest 1 1 and a basic structure horizontal 4b fixed to the vehicle body 100.
  • the mobile structure 4a rests on the base structure 4b when the seat 1 is in the folded position (see Figures 4a and 4b).
  • FIGs 1a and 1b also appears the support 5 loop strand 3 attached to the body 100 independently of the seat frame 4.
  • This support 5 comprises two longitudinal flanges 5a and 5b, on which an axis mechanical 51 is mounted transversely in rotation.
  • a coil return spring 52 extends along the mechanical axis 51 in connection with the arm 31 which carries the loop strand 3 at its end: thus, the arm 31 and the loop strand 3 can move in rotation around said mechanical axis 51 under the restoring force exerted by the spring 52.
  • the loop strand 3 is in a position of stable use, forming an angle of about 60 ° with its support 5.
  • a drive rod 41 of the basic structure 4b comes to exert a force on a cam 6 mounted in rotation about a fixed transverse axis X'X of the base structure 4b, located vertically of the mechanical axis 51.
  • the arm 31 of the loop strand 3 is then held in this position by an articulation between a connecting finger 32 coming transversely from the arm 31 and the cam 6.
  • This cam 6 thus controls the position of the loop strand arm 31 by exerting an antagonistic force the restoring force exerted by the spring 52 on said arm 31.
  • FIG. 1 For the seat 1 to move from the position of use - illustrated in Figures 1a and 1b, to a folded position - illustrated by Figures 4a and 4b - the backrest 1 1 of the seat 1 is folded towards the seated by pushing 12 (arrow F1) on the back 1 1 d of the backrest 1 1.
  • the partial perspective view of Figure 2 shows the seat back 1 1 according to an intermediate folding position between the use position and the folded position.
  • FIG. 3a the diagrams of Figures 3a and 3b illustrate the articulation between the cam 6 and the connecting finger 32 of the loop strand arm 31, respectively in the use position and in the storage position of the seat 1 folded.
  • the arm 31 makes an angle of approximately 60 ° with the horizontal plane of the box 100.
  • the cam 6 has a concave flange 61 on which the transverse connecting finger 32 bears so that the cam 6 constrains the arm 31 in the use position against the return force of the spring 52 (see Figure 1b).
  • the loop strand arm 31 constrained by the restoring force of the spring 52, rotates about its mechanical axis 51 - in counter-rotation with respect to the cam (arrow F4) - until reaching a substantially horizontal storage position ( Figure 3b).
  • the loop strand is then said in the retracted position.
  • the transverse connecting pin 32 of articulation of the cam 6 on the loop strand arm 31 also rotates with the arm 31 around the mechanical axis 51, between the position of use ( Figure 3a) and the storage position ( Figure 3b).
  • FIG. 4a shows in particular a retracted storage position of the seat 12 in a housing 101 of the box 100, the backrest 11 being disposed on the seat 12.
  • the driving rod 41 is in a horizontal position corresponding to the cam position 6 (see Figure 3b) in which the loop strand 3 is in the retracted storage position.
  • FIG. 4b more particularly illustrates the relative positions of the cam 6, the transverse connecting finger 32, the loop strand 3 in the retracted position and the transverse mechanical axis 51 carrying the return spring 52 in integral connection with the loop arm loop 31.
  • FIG. 5 illustrates such an extraction of the seat 1 by pushing upwards (arrow F5), the seat is already slightly raised in this view.
  • the thrust is exerted using the extraction handle 55 which allows the detachment of the cam 6 of the transverse connecting finger 32 and thus the loop strand arm 31 without effort, the finger being in single contact against the cam 6 without any constraint.
  • the seat 1 can then be totally extracted from the vehicle, leaving the loop strand 3 in the retracted position thanks to the restoring force of the spring 52.
  • the transverse connecting finger can be integral with the cam, the arm then having a flange of curvature adapted to the articulation with the cam through this finger.
  • the transverse connecting finger can be fixed or roll on itself.
  • the cam can take any appropriate shape (slide, ramp, hook, etc.).
  • the spring can be replaced by any elastic return means (blade, seal, clips, etc.).
  • the loop arm can be advantageously locked in the use position to neutralize the return force, which allows not to add additional stress to the seat belt in the use position, for example in the event that the position control mechanism ceases to be effective.
