Definitions

  • Headrest comprising a pallet mounted in rotation on the frame
  • the invention relates to a headrest of a motor vehicle seat.
  • the invention aims to overcome these disadvantages.
  • the invention proposes a motor vehicle seat headrest comprising:
  • An injected plastic pallet whose upper part is rotatably mounted relative to the central part of the U, said pallet comprising, molded in one piece with it: an interlocking means ensuring its rotational mounting,
  • a locking means according to a plurality of predefined angular positions, said locking means cooperating with at least one of the branches of the U to effect locking.
  • the positioning terms in the space (upper, lower, front, rear, ...) are taken with reference to the headrest disposed in the vehicle.
  • the proposed arrangement makes it possible to achieve a particularly simple and economical way a headrest whose pallet is adjustable in inclination.
  • FIG. 1 is an exploded perspective view of a headrest according to one embodiment
  • FIG. 2 is a perspective view of the rear face of the pallet, according to the embodiment of FIG. 1,
  • FIG. 3 is a perspective view of the rear face of the pallet, according to the embodiment of FIG. 1, mounted in rotation on the armature and according to various angular adjustments,
  • Figure 4 is a schematic representation in perspective of a separation zone between two notches, according to a particular embodiment.
  • a headrest 1 of a motor vehicle seat comprising:
  • An armature 2 formed of a rod, in particular a metal rod, in the shape of an inverted U, the arms 3 of said U being intended to be mounted at the top of the backrest of said seat,
  • An injected plastic pallet 4 whose upper part is rotatably mounted relative to the central part of the U so as to allow an angular adjustment of its position, in order to optimize the comfort of the passenger's support, said pallet comprising , molded in one piece with her:
  • An interlocking means 5 ensuring its rotational mounting
  • a locking means 6 according to a plurality of predefined angular positions, said locking means cooperating with at least one of the branches 3 of the U to effect locking.
  • the interlocking means 5 comprises at least one - here two - elastically deformable hook 17 fitted into tight contact on the frame 2.
  • the locking means 6 comprises at least one tab 7 projecting in the lower rear part of the pallet 4, said tab being placed in abutment against a branch 3 of the U and comprising a plurality of notches 8 arranged to receive said branch, said tab deforming elastically, as a whole and / or locally, when passing from one notch 8 to the other, each of said notches defining a predefined angular position of said pallet.
  • two lugs 7 are respectively provided against each leg 3.
  • the lug 7 comprises an oblong opening 9 extending along said lug, said opening being provided with notches 8 and receiving the leg 3 of the U in close contact, the walls of said opening diverging from one of the another elastically when passing from one notch 8 to the other.
  • Zone 10 is here formed of a projection 11, said projection being mounted on a tab 12 elastically retractable.
  • the front face of the pallet 4 is covered with a block 13 of flexible material forming a support cushion.
  • the block 13 is under a layer of a coating 14, said block being in particular in the form of foam.
  • a separate block 13 could be interposed between the coating 14 and the pallet 4.
  • Block 13 is coated with a coating material 14.
  • the periphery - here on the rear face - of the pallet 4 comprises a plurality of pins 15 planted in the periphery of the covering material 14 once tensioned, so as to ensure its fixation.
  • a shell 16 is associated facing the rear face of the pallet 4, said shell masking the pins 15.
  • the shell 16 extending here behind the frame 2, it comprises oblong openings, not shown, corresponding to those of the legs 7, in order to allow the rotation of the pallet 4 with respect to the frame 2.
