Definitions

• the invention provides a system for adjusting the longitudinal position, and locking in the adjusted position, a sub-assembly, in particular a seat, on the horizontal floor of the passenger compartment of a motor vehicle.
• the invention relates more particularly to a system for fitting out the interior of a motor vehicle of the "people carrier" type which must have great fitting possibilities, and in particular great modularity as regards the number of seats or of demountable sub-assemblies arranged in the passenger compartment, that the number of positions that these sub-assemblies are likely to occupy.
• this design uses as many pairs of shuttle slides as there are seats desired and, if it is not desired that the slides are visible in the passenger compartment, they must be arranged in the bottom of slides embedded in the floor, which makes it difficult to attach a seat to the upper faces of the sliders insofar as these are not visible and are masked by means, in the form of a brush, of partially closing the slit longitudinal median of the rail-shaped slide.
• the invention aims to propose a new design of an adjustment system of the type mentioned above which overcomes these drawbacks.
• the invention provides a system characterized in that the lower end of at least one of the feet is equipped with a mobile expandable mechanism controlled between: - a first position, called engagement or disengagement, in which two locking members of the mechanism, with symmetrical action and opposite with respect to a median longitudinal plane, are in an inwardly retracted position in which their transverse bulk allows the vertical introduction, or extraction, of the mechanism into the slide through a median longitudinal slit of the latter delimited by two longitudinal and parallel upper edges of the slide;
• a mobile expandable mechanism controlled between: - a first position, called engagement or disengagement, in which two locking members of the mechanism, with symmetrical action and opposite with respect to a median longitudinal plane, are in an inwardly retracted position in which their transverse bulk allows the vertical introduction, or extraction, of the mechanism into the slide through a median longitudinal slit of the latter delimited by two longitudinal and parallel upper edges of the slide;
• a second extreme position in which the two locking members each extend transversely towards the outside opposite an internal portion of one of the upper edges of the slot with which they cooperate by hooking, to immobilize the foot vertically and longitudinally relative to the slide; passing through at least one intermediate position, called the adjustment position, in which the two locking members each extend transversely towards the outside opposite said internal portion of one of the upper edges of the slot, to vertically retain the foot relative to the slide and allow longitudinal movements of the foot relative to the slide.
• the two locking members are two locking levers, each of which is pivotally mounted, in the vicinity of its lower end, around a longitudinal axis of articulation carried by the foot and whose active upper part is of profile complementary to the profile of the internal portion opposite an edge of the slot of the slide;
• each lever is shaped into a hook which cooperates with the lower hooking face of said internal portion;
• the lower attachment face of said internal portion comprises a series of longitudinally distributed notches, each of which constitutes a locking notch capable of receiving the hooked lower end of a locking lever;
• the lower ends of the two levers are mounted articulated around the same longitudinal lower pivot which is slidably mounted in a lower median vertical lumen and on which a first operating member acts, and the mechanism comprises two rods maneuver, with symmetrical and opposite action, each of which is articulated at its upper end around a same longitudinal upper pivot which is slidably mounted in an upper median vertical lumen and on which a second operating member acts, and each of which is articulated at its lower end on a locking lever, near the upper end of the latter;
• FIG. 1 is a schematic perspective view which illustrates a sub-assembly associated with two parallel slides for adjusting the longitudinal position and locking the sub-assembly;
• - Figure 2 is a detailed perspective view which partially illustrates a section of a slide according to the teachings of the invention
• - Figure 3 is an end view, partially in cross section, on which the lower part of a foot is illustrated in association with a slide, the assembly being represented during a phase of engagement of the foot in the slide
• - Figure 4 is a view similar to that of Figure 3 in which the foot is illustrated in the adjustment position
• FIG. 5 is a view similar to that of Figure 4 in which the foot is illustrated in the locked position
• FIG. 6 is a view similar to that of Figure 3 in which the foot is illustrated during its release phase out of the slide;
• - Figure 7 is a top view, in partial section, of the system illustrated in the retracted position of the expandable mechanism. ;
• FIG. 8 is a diagram illustrating the two actuators and their cooperation with the expandable mechanism.
• FIG. 1 shows a sub-assembly 20, which is for example a removable seat of a motor vehicle, comprising a rigid structure or frame of which a lower part 22 is equipped, at its four opposite angles, with four feet 24 d substantially vertical orientation.
• Each of the two pairs of aligned feet is designed so that the lower vertical ends of the feet 24 are received inside two runners, or longitudinal and parallel slides 26 which are intended to be fixed to the horizontal floor of a motor vehicle. (not shown), for example on the upper face of the latter or, alternatively, housed in longitudinal grooves of the floor.
• each of the two slides 26 has a longitudinal symmetry of design with respect to a median longitudinal vertical plane P and it is here produced in the form of '' a longitudinal profile in cut and folded sheet metal.
• Each slide has, in cross section, a general shape of U open at its upper part.
• the slide 26 essentially consists of two opposite lateral wings 28 which are connected together, at their lower ends, by a flat horizontal bottom 30.
• each lateral wing 28 extends parallel and are of vertical orientation. At its upper end, each lateral wing 28 is extended transversely inwards by a sheet metal part folded inwards and downwards which constitutes an upper edge 32 in the form of a box of the slide 26 whose upper faces 33 are flat and the lower faces of which constitute the internal portions 36 of the upper edges 32 within the meaning of the invention.
• the upper edges 32 define between them a longitudinal central slot 38 of the slide 26 of transverse width L1.
• Each of the upper edges 32 comprises, as can be seen in particular in FIG. 2, a series of notches 40 distributed longitudinally in a regular manner along the internal portion 36 of the edge 32 each of which constitutes a locking and locking notch as this will be explained later.
• the mechanism 42 consists essentially of two locking levers 46 which extend substantially vertically and each of which is articulated, by its lower end 48 and around a longitudinal axis A1, on a lower central pivot 50 which is received couiquel in a lower lumen 52 which is median and which extends vertically in the lower portion of the lower part 44 of the foot.
• Each locking lever 46 has an active upper part 56, the upper face 58 of which is in the form of a hook complementary to the profile of the face. lower 37 of the internal portion 36 of the upper edge opposite 32 of the slide 26.
• the profile of the hook-shaped upper face 58 is also such that, as will be explained below, the free end 60 of each hook is capable of at least partially penetrating a notch 40.
• the lower part 44 comprises two wings 47, the lower faces 51 of which carry shoes 53 which are capable of abutting vertically, then of sliding longitudinally, on portions of upper horizontal planar surfaces 55 opposite the upper edges 32 boxed rail 26.
• a pair of rods or rods 62 is provided for controlling the pivoting movements of the locking lever 46 about their axes A1.
• Each of the control rods 62 is articulated at its upper end 64, around a longitudinal axis A2, on a median upper pivot 66 which is slidably received in an upper lumen 68 which is median and which extends vertically in the portion upper of the lower part 44 of the foot.
• each control rod is articulated, around a longitudinal axis, on a locking lever 46 in the vicinity of the active upper end 56 of the latter.
• first operating member or mechanism 72 which is connected to the lower pivot 50 to control the vertical movements in sliding of the latter in the lower lumen 52 between maximum lower and upper positions defined by the lower and upper bottoms of the light (see Figure 8).
• second operating member or mechanism 74 which is connected to the upper pivot 66 to control the vertical movements in sliding of the latter in the upper lumen 68 between defined lower and upper maximum positions. by the lower and upper bottoms of light.
• the lower pivot 50 is in the lower extreme position and the upper pivot 66 is in the upper upper position to cause retraction of the expandable mechanism 42, the maximum transverse width L2 of the mechanism being less than the width L1 of the slot 38 to allow vertical introduction from top to bottom of the levers 46 into the slide 26.
• the engagement continues until the pads 53 come to bear on the portions of horizontal surfaces 55 as illustrated in FIG. 4.
• the altitude of the hooks 58, 60 that is to say the vertical clearance which exists between their ends 60 and the lower faces 37 is determined by the abutment of the pads 53 against the portions of horizontal surfaces. In the position illustrated in FIG. 4, it is possible to adjust the longitudinal position of the foot 24 relative to the slide 26.
• the user acts on the first operating member 72 to cause the lower pivot 50 to rise to its extreme upper position , illustrated in Figure 5.
• the vertical stroke upwards of the lower pivot 50 causes a vertical displacement upwards and a slight simultaneous pivoting of the levers 46.
• the user acts on the first operating member 72 to again lower the pivot lower towards its lower extreme position, that is to say that the expandable mechanism is found in its contracted state identical to that illustrated in FIG. 3 in which the maximum transverse width L2 of the mechanism 42, is less than the width L1 of the slot 38 to allow its extraction from the slide 26.
• one or more feet 24 can be produced in accordance with to the teachings of the invention, for example two front feet or two rear feet.
