Definitions

• the present invention relates to a car seat or the like for children.
• a seat generally comprises a seat, a backrest and various elements of comfort and safety such as for example a headrest, or headrest, in the upper part of the backrest.
• the headrest usually consists of a support plate forming the headrest itself and, projecting from both sides of the headrest, two lateral cheeks that "frame" the child's head in order to maintain it. It is often possible to adjust the height of the headrest on the backrest as the child grows up. To do this, the support plate of the headrest is movable vertically along the backrest, which allows to use the seat for a relatively long period of infancy.
• the present invention aims to avoid this disadvantage by providing a car seat for children whose headrest is adjustable both in height and width, the adjustment operations in height and width of the headrest being fast and simple to perform.
• the subject of the invention is a child car seat as shown above, in which the lateral headrest cheeks are movable and guided horizontally on the support plate and each of the lateral cheeks of the headrest comprises at least a maneuvering finger adapted, during a vertical displacement of the support plate relative to the backrest, to slide simultaneously, on the one hand, in a corresponding guiding light of horizontally oblong shape, formed in the support plate, and on the other hand, in a corresponding guide groove formed in the backrest, of oblong shape, substantially inclined relative to the general axis of the backrest so as to move away from it towards the top of the backrest, so that the vertical displacement of the support plate relative to the backrest is accompanied by a change in the spacing of the lateral cheeks of the headrest.
• the inventive idea is to enslave, by a simple and effective solution, the spacing of the lateral cheeks of the headrest to the position thereof relative to the folder.
• the width and height adjustments of the headrest are performed concomitantly, in a single manipulation, ensuring the ease of use and scalability of this child seat.
• the invention also relates to a car seat for children as presented in the introduction, wherein the side cheek of the headrest are movable and guided horizontally on the support plate, and the backrest comprises, on either side of a vertical median plane of the backrest, at least one suitable operating finger, during a vertical displacement of the support plate relative to the backrest, to simultaneously sliding, on the one hand, in a corresponding guiding light, of horizontally oblong shape, formed in the support plate, and on the other hand, in a corresponding guide groove formed in a side cheek of the headrest, of shape oblong, substantially inclined relative to the general axis of the backrest so as to move away from it by moving towards the bottom of the backrest, so that the vertical displacement of the sup plate relative to the backrest is accompanied by a change in the spacing of the lateral cheeks of the headrest.
• the support plate has at least one strap guide opening for a child holding strap, so that the vertical position relative to the backrest of the support strap is automatically adjusted, at the same time as the height and width of the headrest.
• each of the lateral cheeks of the headrest may have, for example,
• At least one horizontal rib intended to cooperate with a corresponding horizontal rib of the support plate, and / or

• Figure 1 shows a child car seat generally designated by the reference 1.
• the seat 1 comprises a base 3 on which is mounted a shell whose upper part forms a backrest 2 and a lower part forms a seat 4 with two lateral returns forming armrests. All of these main elements are covered with padding elements, not shown in the drawing, arranged for example in a cover.
• the backrest 2 is equipped in its upper part with a headrest 5 adjustable in height, comprising two side cheeks 6 and 7 of section L-shaped, provided to wedge the head of the child.
• the "bottoms" of these two lateral cheeks 6 and 7 are interposed between a headrest plate 8 and a harness plate 9 mounted vertically on the backrest 2.
• the headrest plate 8 is fixed at 8a and 8b (see Figure 4) by screws or clips (not shown) on the harness plate 9 at 9a and 9b (see Figure 5).
• the two lateral cheeks 6 and 7 of the headrest 5 have horizontal ribs 21, 22 (see FIG. 3) which cooperate with horizontal ribs 10 formed on the harness plate 9 (see FIG. 5) to guide the horizontal translation of the lateral cheeks. 6 and 7 with respect to the harness plate 9 and to the headrest plate 8.
• the harness plate 9, shown in greater detail in FIG. 5, has two slots 11 and 12 of horizontally oblong shape, each traversed by a maneuvering finger 13, 14 of one of the lateral cheeks 6, 7 of the headrest 5. .
• the two fingers 13, 14 ensure a synchronization of the horizontal displacement of the lateral cheeks 6, 7 of the headrest 5.
• the length of the lights 11, 12 in the harness plate 9 defines the maximum horizontal movement of the operating fingers 13, 14 of the cheeks 6, 7, and consequently the maximum spacing of the side flanges 6, 7.
• Two apertures 15, 16 of suitable shape are also provided in the harness plate 9 to form passages of straps (not shown) for holding the child.
• the harness plate 9 also has vertical ribs 17 which cooperate with vertical ribs 23 of the backrest 2 (see FIG. 6) in order to guide the vertical translation movement of the harness plate 9 on the backrest 2.
• the backrest 2 has two oblong grooves 18 and 19 symmetrically inclined relative to the general axis A of the backrest 2, so as to diverge towards the top of the backrest 2.
• the operating fingers 13, 14 of the lateral cheeks 6, 7 of the headrest 5 slide in these grooves 18, 19 during a vertical displacement of the headrest 5 with respect to the backrest 2 of the seat 1.
• the two lateral cheeks 6, 7 of the headrest 5 are close together.
• the operating fingers 13, 14 of the two lateral cheeks 6, 7 are located at a lower end of the guide grooves 18, 19 of the backrest 2 and abut against the inside of the slots 11, 12 of the harness plate 9.
• FIGS. 9 to 11 represent another example of a child car seat according to the invention, in which the headrest plate and the harness plate are a single plate 9 guided vertically on the front of the backrest 2.
• the headrest plate and the harness plate are a single plate 9 guided vertically on the front of the backrest 2.
• FIGS. 9 to 9 only the rear face of a left half of the harness plate 9 is visible. This left half comprises, in the upper part, two upper slider portions 25a, and in the lower part, a lower slider portion 25b.
• the upper slides 25a are slidably mounted in a slot (not shown), of horizontally oblong shape, forming a slide in the upper part of the left side cheek 6 of the headrest 5.
• the lower slide 25b is mounted in a light (no shown), of horizontally oblong shape, forming a slider in the lower part of the cheek 6.
• the right side cheek 7, not shown in FIG. 9, also symmetrically has two sliders, one in upper and lower part of the cheek 7, to receive lower and upper slides of the right half (not shown) of the harness plate 9.
• the sliders of the harness plate 9 have an enlarged sole (not shown), projecting on the front face of the harness plate 9, which ensures a retention, along the general axis A of the backrest 2 and along an axis perpendicular to the general plan backrest 2, the corresponding side cheek 6 or 7 on the harness plate 9, while allowing the side cheeks 6, 7 of the headrest 5 to move in the horizontal direction relative to the harness plate 9.
• the synchronization of the displacement of the lateral cheeks 6, 7 is ensured by means of a finger 13, 14 of each of the lateral cheeks 6, 7 which passes through an oblong horizontal light 11, 12 corresponding to the harness plate 9, and slides in a guide groove (not shown in FIG. 9) corresponding inclined backrest 2.

• the locking rod 39 is equipped with two parallel fingers intended to penetrate the notches of the racks 31, 32 of the backrest 2.
• a simple vertical pull exerted upwardly on the handle 34 against a return spring 40 of the handle 34, to unlock the adjusting device 33.
• the return spring 40 is supported on the one hand on a stop 41 secured to the handle support 35 and on the other hand on a stop 42 integral with the handle 34.
• the operator moves the headrest 5 vertically along the backrest 2, to another position, for example the position shown in Figure 8, before releasing the tension exerted on the handle 34.
• the headrest 5 is then locked in a new position.
