Definitions
- the invention relates to a motor vehicle seat headrest.
- a flexible coating cap defining a pocket for receiving said box provided with said block, said cap comprising a front coating format provided with a first edge and a peripheral coating format provided with a second edge, said formats being interconnected edge to edge by a seam,
- an electrical heating circuit based on conductive ink printed on the back of said front format, said circuit comprising a network of printed resistors connecting on either side to two printed current-carrying strips intended to be connected to the poles an electric generator external to said headrest.
- Such an arrangement makes it possible to heat the headrest to improve the comfort of a passenger.
- connection between the printed strips and the connection cables to the generator - being made for example by pinching said strips or even by a conductive glue - risk of generating "hard spots" on the back of the cover that are detrimental to the comfort of the headrest.
- the object of the invention is to overcome these drawbacks.
- the invention proposes a motor vehicle seat headrest, said headrest comprising:
- a flexible coating cap defining a pocket for receiving said box provided with said block, said cap comprising a front coating format provided with a first edge and a peripheral coating format provided with a second edge, said formats being interconnected edge to edge by a seam,
- an electrical heating circuit based on conductive ink printed on the back of said front format, said circuit comprising a network of printed resistors connecting on either side to two printed current-carrying strips intended to be connected to the poles an electrical generator external to said headrest, said headrest further having the following characteristics:
- said box is provided with two connectors intended to be connected to said poles,
- said front format has two peripheral tabs from material, said tabs having a connecting end connecting to said first edge and a free end, said tabs projecting inside said cap,
- each of said printed strips has a connection part extending respectively over each of said legs up to its free end where it is provided with a reciprocal connector fitting with the corresponding connector
- connection between the connectors and the reciprocal connectors is easily made, said connection being made at the level of the box, therefore at a distance from the bearing face of the passenger's head, which avoids the appearance of "hard spots” detrimental to the comfort of the head restraint.
- FIG.1 is a schematic exploded partial perspective view of a headrest according to one embodiment
- FIG.2b are schematic partial cutaway perspective views of the headrest of Figure 1, with the connectors and reciprocal connectors disconnected ( Figure 2a) and connected ( Figure 2b),
- FIG.3b are schematic sectional views of the headrest of the previous figures around a connecting end ( Figure 3a) and plumb with said end ( Figure 3b),
- FIG.4 is a schematic partial perspective view of a cover of the headrest of the previous figures, said cover being provided with a reciprocal connector,
- FIG.5 is a schematic front view of the internal face of a front format provided with reciprocal connectors according to one embodiment.
- a motor vehicle seat headrest 1 comprising:
- a metal frame 2 - here in the form of a metal tube shaped like an inverted U - for mounting on a backrest of said seat,
- a box 3 based on molded plastic material, for absorbing energy in the event of an impact of the head of a passenger on said headrest, said box being mounted - in a fixed or height-adjustable manner - at the top of said armature,
- a flexible covering cap 5 defining a pocket for receiving said box provided with said block, said cap comprising a front covering format 6 provided with a first edge 6a and a peripheral covering format 7 provided with a second edge 7a, said formats being joined together edge to edge by a seam 8,
- an electric heating circuit based on conductive ink printed on the back of said front format, said circuit comprising a network of printed resistors 9 - here shaped like twists - connecting on either side to two printed routing strips 10 current intended to be connected to the poles of an electric generator external to said headrest, said headrest further having the following characteristics:
- said box is provided with two connectors 1 1 intended to be connected to said poles,
- said front format has two peripheral tabs 12 from material, said tabs having a connecting end 13 connecting said first edge and a free end 14, said lugs projecting inside said cap,
- each of said printed strips has a connection part 15 extending respectively over each of said tabs to its free end 14 where it is provided with a reciprocal connector 16 - the attachment between the printed strip 10 and the reciprocal connector 16 is doing for example by pinching, conductive glue, etc. - fitting with the corresponding connector 11.
- the conductive ink is notably printed by screen printing.
- the conductive ink comprises a polyurethane-based matrix in which conductive particles are dispersed.
- the lugs 12 are arranged at the bottom of the front format 6, so as to be positioned at the level of an opening 17 of the cover 5 provided at the bottom of said cover to allow the insertion of the box 3 at the interior.
- the front format 6 is based on a complex comprising, successively associated with each other:
- a soft foam comfort underlay the heating circuit being printed on the back of the covering layer, so as to be positioned as close as possible to the passenger's head and to be protected by said comfort underlay.
- the cap 5 is fitted on the padding block 4.
- an additional backing sub-layer in knitted fabric arranged at opposite the covering layer relative to the comfort underlayer, so as to facilitate sliding between the cap 5 and the block 4 of padding.
- the cap 5 is overmolded, at least in part, by the padding block 4, said block being based on molded foam - in particular polyurethane.
