Description

Child seat, foldable, which can be adapted on a tray, in particular a table.

The present invention relates to a child seat, provided for Stre adapted on a table or any rigid horizontal plane surface, foldable, thus making it compact and easy transportation. Traditionally, indoor children's chairs are light and non-transportable because the feet, which support them, occupy a large floor area. In order to remedy this drawback, it has been proposed, in particular by Patent n °: FR 1,399,681 of April 8, 1964, a seat that can be adapted directly on a table top, made up of two elements in tubes of bent steel fitted with flexible material end caps at each of their ends. One end of each element is supported on the upper part of the table, near its edge, and the other ends are supported by leverage under the table top, in an area farther from the edge than the first ends. These two elements are connected to each other by a rigid seat and back.

The device according to the invention makes it possible to quickly fold and unfold such a type of seat by means of two articulated bars while retaining at the seat the necessary rigidity and its ability to be adapted on a table.

According to other characteristics, the backrest and the seat are made by a continuous strip of washable flexible material, adapting to the said tubular arms, the two b-arres are articulated in the form of a com¬ not, fixed to the tubes by riveted axes which, by means of axes and stops, maintain the shape of the assembly and allow folding by bringing the two support arms together.

According to one embodiment, the articulated bars are provided fixed, spaced apart, to the lower part of the tubes, thus acting as a spacer, to stiffen the assembly, in the position of use and to obstruct the triggered sag under the influence of the child's weight.

According to other particularities of the invention, means are provided to avoid an inevitable deformation of the flexible material of the seat due to the weight of the child and prevent the baby's buttocks from becoming lodged in the free part between two compasses, and on the other hand to improve the rigidity of the whole. Thus, according to an essential characteristic, the deformation of the washable flexible material is suppressed by the adjou- tion, on its seat part, of two rigid plates, for example of ISO-REL, or of plastic, arranged in parallel, on either side of. the folding axis of the two compasses,

received in two separate housings of said flexible material. According to other characteristics, a third compass is provided on the back of the backrest. Two rigid plates are provided in the part made of flexible material defining the backrest, on either side of the axis of the compass, independent and spaced from the seat plates, to allow the assembly to be folded.

The articulation points of the third compass also serve as an anchor point for the safety strap.

In the drawings, provided by way of illustration of the invention: - Figure 1 shows, in perspective, the unfolded seat ready for use, according to a first embodiment;

- Figure 2 shows the seat seen in profile in position on a table;

- Figure 3 shows, seen in plan, from above, the unfolded seat (Position A) and partially folded (Position B); - Figure 4 indicates, seen in section, the position of the compasses relative to the tubular uprights.

- Figure 5 shows, in detail, enlarged, the articulated part of the two compasses;

- Figure 6 shows a perspective view of the assembly, according to a second embodiment;

- Figure 7 shows a sectional view, along a or b, of Figure 6 in the partially folded position.

- Figure 8 shows a view corresponding to Figure 7 in the use position. The seat consists of two metalli¬ cal tubular support arms (1) and (2) each having a vertical part bent at 90 ° at both ends. At the upper part, the elbow is extended by a horizontal part, itself bent at 90 ° and comprising a rubber end piece (4). At the lower part, the elbow is extended by a horizontal part, followed by an oblique part at the end of which a bend again returns the axis of the tube, perpendicular to the underside of the table; the end also has a rubber tip (4). It is expected that the distance between the tips of the upper and lower part is zero. A continuous strip of washable flexible material, forming a seat and back (3), fits over the arms, either by stitching or by welding, or by pins inserted in holes made in the tubular arms. - 3 -

res, or by metal jumpers acting by spring system around the tubular arms. In the rear center of the seat, there is a strap (9) intended to receive a seat belt (8). Two articulated metal bars (5) acting around fixed (6) and mobile (7) riveted axes, and located below the tubes (1) and (2), provide the possibility of extension and retraction from the whole. These articulated bars include a system for blocking the opening by a stop (10) and (10 ') and immobilization by punched parts (11) and (11') in the longitudinal position during use. A seat belt (8) fixed at the rear and in the upper part of the rear vertical sections of the arms (1) and (2) and passing through the loop of the strap (9) connected to the seat (3) in the rear middle part , keeps the child in the sitting position by preventing him, thanks to this offset connection towards the rear of the strap on the seat, from sliding forward.

Figure 3, Position A, shows the unfolded seat. Figure 3, Position B, shows the partially folded seat. The object of the invention is to provide a quick and easy solution for folding the seat by pressing with one hand on the articulated bars (5), side opposite to the stop (10), in order to produce their sagging. The unfolding of the seat is done by acting in reverse and pushing with the hand to bring the branches of each compass in the extension of one another. Locking in this position ensures, by means of the stop (10) and (10 ') and of the punched parts (11) and (11'), as a priority, the rigidity in the spacing necessary for the use of the seat, forming a spacer. It also makes it possible to ensure additional support for the flexible part of the seat and to obstruct the flexing triggered by the weight of the child. According to the second embodiment of the invention, illustrated in FIGS. 6 to 8, the deformation of the flexible material (3) is eliminated by the addition of two plates, of the IS0REL type (13) and (13 ′), coming, after unfolding of the seat, pressing on the two compasses (5), according to sections a and b. During folding, the plates retract parallel to the axis of the seat. These plates, like IS0REL, are covered with foam for reasons of comfort. They are housed in compartments formed in the flexible material, for example the fabric forming an envelope, delimited - 4 -

by peripheral seams or welds.

The addition of a third compass (12) gives rigidity to the backrest and serves as an anchor for the safety strap. For reasons of rigidity, and also of symmetry, two ISOREL-type plates (14) and (14 '), identical to the plates (13) and (13'), strengthen the backrest and are also housed in compartments, mé ¬ swam in the envelope fabric, delimited by seams. It should be noted that the presence of the plates facilitates the folding of the fabric during the folding of the seat. It is understood that the use of materials other than ISOREL, and having sufficient rigidity, is included in the present application.

The device according to the invention is particularly intended for rapid unfolding and folding of a child seat which can be adapted on a tray, in particular a table. The invention is applicable to the field of household furniture, in boats and caravans, as well as in restaurants.

It remains to be understood that the invention is not limited to the embodiment described and shown but that it encompasses all the variants thereof, so the spaced positioning of the bars under the tubes in the seat area is not limiting, other positions which can be envisaged, for example, distributed between seat and backrest.
