Definitions

  • the invention concerns in a general way blanking members adapted to be installed on a seat, notably a vehicle seat, in place of a headrest sheath.
  • a headrest including a frame of inverted U- shape and a cushion that covers the horizontal branch and a portion of each of the vertical branches adjacent the horizontal branch.
  • the portion of each vertical branch that is not covered by the cushion forms a rod adapted to be pushed into a sheath to a greater or lesser depth.
  • a blanking member of this kind that includes a body and a cap disposed at one end of the body.
  • the cap covers on the top of the seat-back of the seat the opening provided in line with the receiving member.
  • the body is cylindrical and is similar to that of a sheath for receiving a headrest branch.
  • the aim of the invention is to provide a blanking member of this kind that is particularly simple, convenient and economical to produce.
  • the invention proposes a blanking member to be installed on a seat, notably a vehicle seat, in place of a sheath for receiving a headrest rod, which blanking member comprises an elongate body and a cap disposed at one end of said body, characterized in that said body is formed by at least two fins with at least one fin that comprises a clipping abutment projecting from its edge and at least one fin that comprises an insertion abutment projecting from its edge, said fin that comprises said clipping abutment being adapted to be deformed in the proximity of that abutment.
  • the blanking member comprises four of said fins with a regular annular distribution so as to form two plates disposed transversely to each other;
  • the blanking member comprises two pairs each comprising one of said clipping abutments and one of said insertion abutments, offset axially, with one plate that comprises said two insertion abutments opposite each other whereas the other plate comprises said two clipping abutments opposite each other;
  • each of said clipping abutments is part of a clipping tooth further comprising a ramp, said tooth tapering toward the free end of said body;
  • each of said insertion abutments and each of said clipping abutments extends transversely to the lengthwise direction of said body;
  • said body has a pointed free end, opposite said cap, said fins tapering toward said end;
  • said blanking member is in plastic material molded in one piece.
  • the invention also proposes a seat, notably a vehicle seat, comprising a frame that has two members for receiving a sheath for receiving a headrest rod, characterized in that it further comprises two blanking members as described hereinabove, each of said blanking members being received in a respective one of said members with each of said members that have a portion engaged between one of said insertion abutments and one of said clipping abutments.
  • each of said bushes comprising a hollow space having on its surface a rib extending transversely to the direction of said recess, at least one of said insertion abutments and one of said clipping abutments being disposed on either side of said rib;
  • said members are plates bent to a U-shape having two orifices each of which has said body pass through it, one of said orifices having a perimeter on either side of which are disposed at least one of said insertion abutments and at least one of said clipping abutments.

  • figure 4 is a view similar to that of figure 3 from a different angle
  • FIG. 1 is a view of the blanking member shown in figures 3 and 4 as seen from below;
  • FIG. 6 is a perspective view of a seat of the invention.
  • FIG. 7 is an elevation view of a blanking member received in a sheath-receiving member.
  • figure 8 is an elevation view similar to that of figure 7 from a different angle.
  • the blanking member 1 is used to blank a member 2 for receiving a sheath.
  • the receiving member is part of a frame of a seat-back 4 of a seat 3.
  • the blanking member 1 includes a cap 5 and an elongate body 6.
  • the cap 5 includes a disk-shaped wall 8 that is extended by an upstanding rim 9 having a frustoconical shape. [35] The cap 5 therefore has a concave side on the surface 10 of which the body 6 is rooted. The cap 5 has a diameter larger than that of the orifices in the member 2 and also larger than that of the orifice in the layer of foam at the top of the seat-back 4 in line with the member 2. [36] The body 6 extends transversely to the cap 5 with the main axis 12 of the body 6 passing through the center of the wall 8 of the cap 5 and more generally disposed coaxially with the cap 5. [37] The body 6 includes two flat elongate plates 14, 15. The plates 14, 15 are disposed transversely to each other and intersect along the main axis 12. Being flat, the plates
  • Each plate 14, 15 has an edge all around their perimeter.
  • Each plate 14, 15 includes two fins 16, 17, the two fins 16 of the plate 14 being disposed on respective opposite sides of the plate 15 and the two fins 17 of the plate 15 are disposed on respective opposite sides of the plate 14. The four fins 16, 17 are therefore disposed alternately and at right angles to each other.
  • the plate 14 is symmetrical with respect to the axis 12 and so the fins 16 are mirror images of each other about that axis 12.
  • the plate 15 is symmetrical with respect to the main axis 12 and so the two fins 17 are mirror images of each other about that axis.
  • the plates 14, 15 each have a T-shape with the portion corresponding to the crossbar extending from the wall 8 in the concave face of the cap 5. These two portions have a cruciform arrangement, each on a diameter and over a height corresponding to that of the rim 9.
  • the portion of the plate 14 corresponding to the stem of the T-shape has two lateral edges globally parallel to each other.
  • the plate 14 At its end opposite the cap 5, the plate 14 has two corners globally chamfered at 45° to form two ramps 20 on the edge of the plate 14.
  • the two lateral edges have, on a portion 21, a step transverse to the axis 12 of the body 6.
  • this portion 21 extends over approximately one quarter of the total length of the plate 14. From edge to edge, the portion 21 has a width 22. This portion 21 has chamfered corners at each end.
  • the central portion of the plate 14 has a width 23 slightly less than the width 22.
  • the plate 14 has a portion 24 of width 22.
  • the plate 14 has a shoulder 25.
  • the plate 14 In the proximity of the shoulder 25, the plate 14 has a rectangular projection 28.
  • the distance between the free end of one projection 28 and the free end of the other projection 28 corresponds to a width 34.
  • the plate 15 has a very short portion of width 23 directly adjacent the horizontal branch described above.
  • the plate 15 has a projecting clipping tooth 38.
  • the free edge of this tooth 38 has on the same side as the cap 5 a portion that is transverse to the axis 12 of the body 6 and forms a clipping abutment 39.
  • the tooth 38 On the other side, i.e. on the same side as the free end of the body 6, the tooth 38 has a ramp 40 so that the tooth 38 tapers toward the free end of the body 6.
  • the plate has a width 41 that is greater than the width 22, 23 and less than the width 34.
  • each fin 17 has an elongate slot 42 in the direction of the axis 12 over a distance globally corresponding here to twice the length of the tooth 38.
  • the plate 15 therefore has two slots 42 to save on the material used to produce the blanking member 1. These slots 42 enable slight deformation of each of these areas of the fins 17 that include a tooth 38 and therefore a ramp 40 and a clipping abutment 39 to allow the teeth 38 to flex when they must retract to clip into means provided for this purpose on the member 2.
  • the plate 15 has a step, on a portion 44, transverse to the main axis 12. This portion 44 of the plate 15 has a width 23 and chamfered corners.
  • the fins 16, 17 are images of each other on rotation through 90° about the axis 12.
  • the plate 15 has chamfered corners so as to have on its edge two ramps 47 like the ramps 20 of the plate 14.
  • the frame of the seat-back 4 includes sheath-receiving members taking the form of pieces 2 of sheet metal bent to a U- shape.
  • Each piece of sheet metal has a transverse branch 50 connecting two similarly oriented branches 51 that are not precisely parallel.
  • Each of the branches 51 is provided with a circular orifice 52. These two orifices 52 are adapted to receive a sheath for receiving a rod of a headrest if the seat 3 is so equipped.
  • the top of the seat- back 4 includes a layer 53 of foam possibly covered with fabric and so an orifice 55 is also provided in this layer 53 in line with the two orifices 52.
  • the layer 53 is adjacent the piece 2 of sheet metal.
  • a blanking member 1 is inserted instead.
  • the blanking member 1 is offered up to the orifice 55, its free end first, and in particular its ramps 20, 47 first.
  • the pointed shape of the free end of the body 6 guides the blanking member 1, in particular through the layer 53 and when it comes into contact with the piece 2 of sheet metal.
  • a second ramp is provided opposite the ramp 40 of the tooth 38 so that the blanking member can be extracted.
  • each fin includes an additional slot.
  • the body includes reinforcing ribs lying in a plane transverse to the axis of the body. Each of the ribs extends between two successive fins.
  • the body includes three fins joined together on the axis of the body and separated from each other at an angle of 120°.
  • the body has only two fins disposed in the same plane and forming only one plate. That plate then includes at least one pair of insertion and clipping abutments.
  • the members for receiving a headrest sheath are cylindrical bushes including a hollow in which a sheath is received.
  • Each bush is provided with fixing means corresponding to the insertion and clipping abutments to allow the blanking member to be clipped into the bush.
  • the blanking member, and in particular its body is shorter than in the case described above of insertion into a piece of sheet metal.
