Description

The present invention relates to a seat side latch with a longitudinal play take-up so as to provide a blockage of the upper profile of the slide with respect to the fixed lower profile thereof.
In fact, in spite of a careful fabrication, the toothing of the rack carried by one of the wings of the fixed lower profile which cooperates with the teeth of the comb carried by the lateral latch pivotably mounted on one of wings of the sliding upper profile of the slide does not always correspond exactly, and there is provided a slight longitudinal play which is unpleasant for the person seating on the seat who feels that this seat is not completely latched, thereby causing a certain degree of apprehension for the passenger, mainly at the moment of an abrupt brakage or at that of a brutal acceleration, which is always the cause of a slight reciprocating motion of the seat.
Attempts have already been made to remedy this defficiency, but the solutions proposed up to now have not proved to be satisfactory since they do not allow a correct and definitive take-up of the longitudinal play and are complex solutions, therefore too costly and which cannot be admitted by the manufacturers (see in this respect FR-A-2 562 004).
The present invention remedies these disadvantages by providing a simple , little costly and elegant solution ensuring a complete take up of the longitudinal play, without increasing the manufacturing cost.
SUMMARY OF THE INVENTION According to the invention , the seat slide hand latch with horizontal play take-up, cooperating with one of the vertical wings of the upper mobile profile of a slide provided with a rack for activating the blockage latch having a comb with teeth of a square section for cooperation with the rounded profile of the bottom of the toothing of the rack, is characterized in that : a) a circular cut-out formed by a boss fixed with the lateral side of a latch is used as an axis of rotation for this latch by extending through an ovalized hole formed on one of the vertical wings of the upper mobile profile, this latch being guided frontwardly by a stamped-out flap of the wing of this same upper profile, then being formed on an upper portion with a horizontal triangular wing formed with a hole receiving one end of a leaf spring working in flexion while an other end of the leaf spring bears inside a stamped-out flap of the rear portion of the wing of the upper mobile profile in such manner that the comb of the latch extends into a rack carried by one of the wings of the lower fixed profile of the slide , the blockage of the comb in the rack being provided by a tilting motion of the latch about the circular cut-out housed in the ovalized hole under action of the leaf spring ; b) the leaf spring exerts, via a free end, a rotation torque on the latch by bracing itself in a hole formed in the wing of this latch in order to bring the circular cut-out to cooperate with two points of the ovalized hole, the leaf-spring having an other end coming to bear on the rear stamped-out flap provided on the lateral side of the upper profile.
Various other features of the invention will become more apparent from the following detailed description.
BRIEF DESCRIPTION.QF IHE DRAWIHG5 An embodiment of the object of the invention is shown by way of example in the accompanying drawings, wherein .
Fig. 1 is a side elevation view, partly in cross section and broken away, of a slide including a hand control latch with a longitudinal play take-up according to the invention , Fig . 2 is a plan view corresponding to Fig. 1 taken susbtantially along line II-II of Fig. 1 • Fig. 3 is a cross sectional view taken along line III-III of Fig, , 1, Fig. 4 is a very enlarged view of an articulation portion of the hand latch of the slide , Fig. 5 is a very enlarged partial cross sectional view showing a tooth of the rack toothing carried by one of the wings of the fixed lower profile in which is engaged a tooth of the comb of the latch.
DETAILED DESCRIPTION QF THE INVENTION Referring now to the drawings, Figs. 1 to 3 show a slide including a lower profile 1 having a U-shaped section (see Fig. 3), the wings la and lb of which being turned over and shaped so as to form a race for balls 2 interposed between the lower profile 1 and a mobile upper profile 3, the upper face 3a of which is connected by any appropriate means to base of the armature of the seat in consideration. Moreover, the outer wing la of the profile 1 is provided with a rack 4 with a substantially rectangular toothing 5 and the upper sides of which are inclined at 5a, 5b (see Fig. 5).
As shown in Fig. 3, the wings 3b, 3c of the mobile upper profile 3 are bent over themselves so as to form sliding guides along the vertical wings lc, Id of the lower profile 1 , enhancing thus the rigidity of the profile 1.
The front vertical side of a latch 10 carries a circular cut-out 6 (see Figs. 1, 2 and 4). The latch 10 is guided frontwardly by a stamped-out flap 7 formed on the vertical wing 3d of the upper profile 3.
Moreover, the latch 10 is normally returned in the latching position of the slide by a leaf spring 19 of which one of the ends is fixed in a stamped-out flap 8 formed in the same vertical wing 3d of the profile 3.
The latch 10, which provides for connecting and blocking the upper sliding profile 3 with respect to the lower profile 1 is pivotably mounted via the circular cut-out 6 housed inside an ovalized hole 11 formed in the wing 3d of the profile 3 (see Figs. 1, 2 and 4), while the end 10a of the latch 10 is retained and guided by the stamped-out flap 7. The latch 10, which is of a standard design, has first a comb 12, namely a horizontal portion formed with equidistant holes thereby defining teeth 13 (see Figs. 2 and 5) which normally extend in the toothing 5 of the rack 4 carried by the wing la of the fixed profile 1.
Moreover , the latch 10 carries at its upper portion a horizontal wing 14 of a triangular shape , the wide portion of which is formed with a hole 15 while, in the front portion of the latch 10, are cut two lugs 16, 17 intended for fixing the slide control. Generally, this slide control is a standard yoke placed in a lower portion of the seat seating portion.
The vertical rear portion 10b of the latch 10 is supported, when lifted for disengaging the comb 10 from the rack 4, in a cut-out boss 20 (see Figs. 2 and 3) which is fixed with the wing 3a of the profile 3.
Attention should actually be drawn on the fact that normally each seat includes, on its lower right and left side portions, two slides which are identical and parallel to that which has just been described ; the armature of the seating portion of the seat being fixed by its lower portions on the two upper profiles 3 of the two parallel slides.
A leaf spring 19, of a curved shape, is supported in the rear stamped-out flap 8 and extends through the hole 5 of the horizontal triangular wing 14 of the latch 10, so that the free end or point 19a of this leaf spring braces itself in the hole 15 formed in the wing of the latch 10.
Thus, when the latch 10 is in the position shown in Fig. 1, the leaf spring blade lifts a rear end of the latch 10 in the direction of arrow Fl (see Fig. 1), the effect of which being to have the teeth 13 of the comb 12 to mesh correctly with the toothing 5 of the rack 4 which is part of the fixed lower profile 1. The effect of this motion is to slightly tilt, in the direction of arrow F2, the front portion of the latch 10 (see Fig. 1), whereby the ovalized hole 11 of the latch 10 comes to bear on two points lla, lib of the oval cut-out 11 formed on the wing 3d of the upper profile 3 (see Fig. 4), thereby preventing any play of the latch 10 and therefore any play between the fixed lower profile 1 and the mobile upper profile 3 of the slide.
The fabrication of the profiles 1 and 3 is in no way modified, the latch 10 is of a standard type, and the members provided for fixation of spring blade 19, the axis of rotation formed by the circular cut-out 6 of the latch 10 and the ovalized hole 11,pertain to an extremely simple fabrication technique and can be manufactured automatically. It should be also noted that the cooperation of the teeth 13 which stand at an angle of 90’ with the bent-over angled toothings 5a, 5b makes also easy a cancellation of the vertical plays between the two profiles 1 and 3 of each slide.
