Abstract
Description
Title of the invention: Motor vehicle seat headrest
[0001] The invention relates to a motor vehicle seat headrest.
[0002] It is known to produce a motor vehicle seat headrest, said headrest comprising: • a rigid connecting structure for said headrest to the top of the seat back, said structure comprising a metal frame having two parallel rods, • an elastically compressible padding cushion attached to said structure, said cushion having an underside from which said rods protrude, • a cover for said cushion based on a plurality of cover formats joined together edge to edge, said cover being fitted over said cushion, said cover comprising a lower area.
[0003] With such an arrangement, it is necessary to provide in the lower area of the cover an opening allowing the rigid structure to be inserted into said cover.
[0004] And when the structure has a large volume, it is necessary to provide an opening of considerable size - in particular of a substantially rectangular shape and not in the form of a simple slit - which can lead to finishing difficulties when the opening is closed once the said structure has been inserted into the cover.
[0005] The invention aims to provide an arrangement that optimizes the finish of such a headrest at the level of its opening.
[0006] To this end, the invention proposes a headrest for a motor vehicle seat, said headrest comprising: • a rigid connecting structure for said headrest to the top of the seat back, said structure comprising a metal frame having two parallel rods, • an elastically compressible padding cushion attached to said structure, said cushion having an underside from which said rods protrude, • a cover for said cushion made from a plurality of cover formats joined together edge to edge, said cover being fitted onto said cushion, said cover comprising a lower area arranged opposite said lower face,
[0007] said lower zone comprising: • a front format having a first transverse edge with a median zone and two lateral zones, said format extending transversely on either side of said cover, • a rear format having a second transverse edge extending along said median zone, said second edge having a profile cooperating with an associated reciprocal profile along said median zone, said format having two longitudinal edges, said second format extending transversely from one of said stems to the other, • two lateral formats, each having a lateral part and a front part projecting transversely inwards, said formats each having a rear internal longitudinal edge sewn to the rear part of a respective longitudinal edge of said rear format, said rear format overlapping said front part, said lateral formats each being provided with an opening for receiving one of said rods in a fitted manner, said opening opening at the intersection between said front part and said rear internal longitudinal edge,
[0008] said first and second transverse edges and said front part delimiting an opening for insertion of said structure into said cover to allow its assembly, each of said rods passing through a respective orifice.
[0009] In this description, the terms of positioning in space (longitudinal, transverse, lateral, lower, front, rear, below, etc.) are taken with reference to the vehicle in which the headrest is located, said vehicle extending longitudinally along its length (X axis), transversely along its width (Y axis) and vertically along its height (Z axis).
[0010] With the proposed arrangement, a large-sized cover opening is achieved with an optimized finish at the level of said opening once closed, in particular due to the covering of the front parts of the side formats by the rear format.
[0011] Other features and advantages of the invention will become apparent from the following description, made with reference to the accompanying figures, in which:
[0012] [Fig.la] and
[0013] [Fig.lb] are schematic cutaway views in partial perspective of a headrest according to one embodiment, the opening of the cover being open ([Fig.la]) and closed ([Fig.lb]).
[0014] [Fig.2] is a schematic view from below of the headrest shown in figures 1.
[0015] With reference to the figures, a headrest 1 of a motor vehicle seat is described, said headrest comprising: • a rigid connecting structure for said headrest to the top of the seat back, said structure comprising a metal frame having two parallel rods, • a cushion 3 of elastically compressible padding attached to said structure, said cushion having an underside 4 from which said rods protrude, • a cover 5 for the upholstery of said cushion based on a plurality of upholstery formats joined together edge to edge - in particular by stitching or by interlocking profiles - said cover being fitted onto said cushion, said cover comprising a lower zone arranged opposite said lower face,
[0016] said lower zone comprising: • a front format 6 having a first transverse edge 7 with a median zone 8 and two lateral zones 9, said format extending transversely on either side of said cover, • a rear format 10 having a second transverse edge 11 extending along said median zone, said second edge having a profile 12 cooperating with a reciprocal profile 13 associated along said median zone, said format having two longitudinal edges 14, said second format extending transversely from one of said rods to the other, • two lateral formats 15 each having a lateral part 16 and a front part 17 projecting transversely inwards, said formats each having a rear internal longitudinal edge 18 sewn into the rear part of a respective longitudinal edge 14 of said rear format, said rear format overlapping said front part, said lateral formats each being provided with an opening 19 for receiving one of said rods in a fitted manner, said opening opening at the intersection between said front part and said rear internal longitudinal edge,
[0017] said first and second transverse edges and said front part delimiting an opening 20 for insertion of said structure into said cover to allow its assembly, each of said rods passing through a respective orifice 19.
[0018] According to the embodiment shown, the structure further includes an energy absorption housing 21 - in case of impact of the head of a seat occupant against the headrest 1 - made of molded plastic material attached to the metal frame.
[0019] According to the embodiment shown, the front format 6 and the rear format 10 are joined laterally to each other by two seams 22 extending laterally on either side of the first edge 7.
[0020] According to an unrepresented variant, the front format 6 and the rear format 10 are laterally connected to each other by fitting complementary profiles respectively fixed on each of said formats, said profiles extending laterally on either side of the first edge 7.
[0021] According to another variant not shown, the front format 6 and the rear format 10 are laterally connected to each other by interlocking profiles respectively fixed on each of said formats, said profiles extending laterally on either side of the first edge 7, said profiles fitting into complementary lateral grooves provided in the housing 21.
[0022] According to the embodiment shown, the profile 12 of the second edge 11 and the reciprocal profile 13 of the median zone 8 fit into a complementary median groove 23 provided in the housing.
[0023] According to an unrepresented variant, the profile 12 of the second edge 11 fits into the reciprocal profile 13 of the median zone 8.
