Slide for motor vehicle seat and vehicle seat

  The present invention relates to the rails for motor vehicle seats, and to the seats of

  motor vehicle comprising such slides.

  More particularly, the invention relates to a rail for a motor vehicle seat comprising a first section and a second section mounted movable relative to each other in a longitudinal direction, the first section comprising a first fixed stop system adapted to cooperate with the second section to limit the relative displacement of the first and

  second section on a first race.

  In known slides of this type, the relative displacement of the first and second profiles on a longitudinal stroke is imposed during the production and assembly of the slide. However, this relative movement of the first and second profiles may be different depending on the type of seat and / or vehicle in which the slide must be adapted. Thus, when it is for example necessary to offer two different types of races for the same model of seat, it is imperative to mount on this seat is a first set of slides offering a first race, or a second set of slides offering a second race different from the first race of the first slide game. This implies, therefore, when assembling the seat on the floor of the vehicle, to choose in advance among several sets of slides of

  way to get the desired run.

  FIG. 1 shows a seat 1 of a motor vehicle which comprises a seat 2 mounted on the floor 3 of the

  vehicle, and a backrest 4 mounted on the seat 2.

  The connection between the floor 3 of the vehicle and the seat 2 of the seat is achieved by means of two parallel rails 5 (only one of which is visible in FIG. 1) making it possible to adjust the position of the seat 1 with respect to the floor 3 of the vehicle, by sliding in the longitudinal direction L. For this purpose, as can be seen in Figure 2, the slideway 5 comprises a female section 6 fixed to the floor 3 of the vehicle and a male section 7 slidably mounted longitudinally in the profile female 6. The male section 7 is directly attached to the lower surface of the seat 2 of the seat, for example by means of screws 70 attached to the seat.

male section 7.

  In the embodiment shown in Figures 2 and 3, the female section 6 has a generally U-shaped section which comprises a lower horizontal bottom 61 from which extend upwardly two side walls 6a each formed by a vertical wing 62 which is extended by a wing return 63 oriented towards the inside of the U and directed towards the bottom 61 of said female section 6. Each wing return 63 and the vertical wing 62 associated therewith delimits a portion sensibly

horizontal 65.

  The male section 7, meanwhile, has a section of inverted U-shaped general shape which comprises an upper horizontal bottom 71 from which extend downwardly two side walls 7a each formed by a vertical flange 72 extending by a flap 73 Each flap 73 of the male section 7 comprises an end portion 73a that extends substantially vertically and parallel to the vertical wings 72. The two end portions 73a are each provided with a edge 73b which comprises at least on a longitudinal portion a projection 74 formed in one piece

  with the flap 73 associated with it.

  As can be seen in Figures 2 and 6, when the male section 7 is mounted inside the female section 6, the flaps 73 and the projections 74 of the male section 7 are housed in a space defined between the vertical flanges 62 and the wing returns 63 of the female section 6, while the wing returns 63 of the female section 6 are housed between the vertical wings 72 and the

flaps 73 of the male section 7.

  In order to allow longitudinal movement of the male section 7 in the female section 6, balls (not shown in the figures) of the same diameter are arranged on either side of the flaps 73 of the male section 7, said balls being held in position. place in the housing formed by the vertical flanges 62 of the female section 6 and the wing returns 63. Thus, each projection 74 extends longitudinally near a wing

vertical 62 of the female section 6.

  As can be seen in FIG. 3, each projection 74 of the male section 7 extends longitudinally between a first end 74a and a second end 74b, which delimit shoulders with the edge 73b of the end portions 73a of the said flaps 73. 7. In order to limit the longitudinal stroke of the male section 7 relative to the female section 6, each projection 74 is intended to cooperate with stop members 64 disposed on the female section 6 when the slide 5 is assembled, it is that is when the male section 7 is mounted

  sliding inside the female profile 6.

  More precisely, the vertical wings 62 of the female section 6 are each provided on their two longitudinal ends with abutment members 64 which are intended to cooperate with the respective ends 74a and 74b of the projections 74 to limit. the displacement of the male section 7 inside the female section on a first predetermined stroke L1 (see FIG. 4). These abutment elements 64 may in particular be made, after mounting the male section 7 in the female section 6, by stamping the longitudinal ends of the vertical flanges 62 of the female section 6, so that said abutment members 64 are constituted by elements protruding beyond the dwellings delimited by said wings 62 and the

wing returns 63.

  In the first embodiment shown in FIGS. 2 to 5, the female section 6 also comprises, in addition to the first fixed stop system formed by the abutment members 64, a second abutment system 8 removably mounted on the vertical flanges. 62 of said profile

female 6.

  This removable abutment system 8 comprises, in the example considered here, two removable abutment elements 9 which are each formed by a substantially vertical wing 91 formed integrally with a substantially horizontal wing 92 intended to cooperate with the projection 74 which is

associated with the male section 7.

  For this purpose, each vertical flange 62 of the female section 6 comprises at least one through opening 66 and a fixing hole 67 associated therewith. Thus, during the reversible establishment of the stop elements 9, it is sufficient to place the horizontal flange 92 of each stop element 9 through the through opening 66 of the female section 6 and to fix the vertical flange 91 of the abutment element 9 by means of a screw 93 intended to be removably received in the fixing hole 67 of the female section 6. When the removable abutment elements 9 are put in place on the female profile 6, the horizontal flange 92 of each abutment element 9 is substantially located above the edge 73b of each flap 73 of the male section 7 while allowing an abutment for example of the end

  74a of the projection 74 of the male section 7.

  Thus, the presence of the removable abutment elements 9 reduces the relative displacement of the male section 7 and the female section 6 on a lower L2 race to the first race L1. This removable abutment system 8 can for example be implemented during the assembly of the seat on the floor of the vehicle, the removable abutment members 9 can subsequently be removed according to the needs of the user, especially when taking in hand of the vehicle. Moreover, this system advantageously makes it possible to remove each removable abutment element 9 and thus increase or not the relative displacement of the female 6 and male 7 sections when the vehicle seat 1 is already

  mounted on the floor 3 of the vehicle.

  In this first embodiment, the stop elements 9 are removably mounted on the female section 6 so that each projection 74 forms a fixed stop system intended to come into contact either with the fixed abutment elements 64 or with the removable abutment elements 9 when these are put in place on the

female profile 6.

  As can be seen in FIGS. 2 and 3, each vertical wing 62 of the female section 6 may comprise a plurality of through-holes 66 associated with fixing holes 67 in order to allow precise longitudinal adjustment of the position of each stop element. 9 so as to selectively limit the relative displacement of the male 7 and female 6 sections on a plurality of races less than the first race L1. In the example considered here, each removable abutment element 9 is disposed between the first end 74a of the projection and one of the fixed abutment members 64 of the female section 6. Naturally, each removable abutment element 9 can also be placed between the end 74b of the projection 74 of the male section 7 and the other fixed abutment element 64 of the female section 6. It is also possible to place removable abutment members 9 on either side of the projection 74 and between the two elements of FIG. fixed stop 64 of the female section 6 to limit the stroke of the female / male section relative to the

  female profile 6 forward or backward.

  FIG. 6 represents a second embodiment of the removable abutment system 8. The removable abutment system 8 here comprises two removable abutment members 10 each comprising a horizontal limb loa disposed facing the substantially horizontal portion 65 of the female section 6 , and a vertical wing 10b material with the horizontal wing loa. Each vertical wing 10b comprises a stamped portion 10c which passes through the through opening 66 formed on the vertical flange 62 of the female section 6. This pressed portion loc is intended to act as a stop for the projection 74 of the male section to to limit its movement in the longitudinal direction L

  on a race lower than the race Ll.

  In this embodiment, the horizontal flange 1a of each removable abutment element 10 is adapted to receive a stud bolt 11 intended to come into contact with the horizontal portion 65 of the female section 6 as it is screwed into the horizontal flange iCa so as to strongly apply the stamped portion 10c against the through opening 66 so as to attach reversibly to the vertical flange 62 of the movable section 6. In this embodiment, each removable stop member 10 or more exactly the stud screw 11 associated with it can be directly screwed or unscrewed when the seat 1 is

  already set up on the floor 3 of the vehicle.

  Moreover, in this embodiment shown in FIG. 6, the projection 74 or more exactly its ends 74a, 74b also form a fixed stop system intended to come into contact either with the fixed abutment elements 64 of the female section 6 or then with the removable stop elements 10 when these are put in

place on the female profile 6.

  In the third embodiment shown in Figure 7, the male section 7 always comprises two projections 74 intended to come into abutting contact with the fixed abutment members 64 of each vertical flange 62 of the female section 6. The male section 7 comprises also at the junctions between its horizontal flat bottom 71 and its vertical flanges 72 two through openings 75 arranged opposite one another and intended to removably receive a pin or an axis 12. The female section 6 comprises, meanwhile, at its horizontal portions 65 stop members 68 so as to limit the stroke of the male section 7 relative to the female section 6 by abutment of the pin 12 against said fixed stop member 68. These elements fixed stop 68 may for example be made by stamping the horizontal portions 65 of the female section 6 during its production. As in the previous embodiments, the male section 7 may comprise a plurality of through openings 75 so as to adjust the longitudinal position of the pin 12 in order to selectively limit the displacement of the male section 7 relative to the female section 6 on a plurality of strokes lower than the base course defined by the relative position of the projections 74 and the fixed stop elements 64

of the female profile 6.
