Definitions

• the present invention relates to a child car seat. For safety reasons, young children travel in car seats which are adapted to their size, and which are themselves fixed on the rear seat of a motor vehicle.
• a car seat for children generally comprises a base resting on the seat of the seat, and a shell, mounted on this base and intended to receive the child.
• the car seat is fixed to the seat, either using straps fixedly mounted on the vehicle, or using one of the seat belts in the rear seats of the vehicle.
• the shell is mounted on the base with a possibility of tilting to allow the child to be either in sitting position, or lying down.
• the slide is fixed on the base and the other part of it is fixed on the shell.
• This slide is arranged in the longitudinal median plane of the hull.
• this solution requires the implementation of a plurality of parts, it has the drawback that the shell and the base are only joined at their longitudinal median plane, so that there is a lateral tilting torque when forces are exerted on the hull. In the long run, this lateral tilting torque can result in deterioration of the assembly. In addition, the increase in the number of parts results in a high cost price, and requires a large workforce to assemble the different parts.
• the object of the invention is to provide a car seat for children, which is simple in design, that is to say in which the number of parts is limited, which is very practical for parents. of the child, in particular by allowing simple and rapid adjustments, and which is of a low cost price.
• the child car seat that it relates to of the type comprising a base intended to be mounted on the seat of a vehicle seat or seat, and a shell mounted on the base with the possibility of tilt adjustment is characterized in that:
• the base on the one hand and the shell on the other hand are made of synthetic material molded by a blowing technique
• the base comprises a curved central and longitudinal upper surface which, centered on an axis situated above the base and oriented transversely thereto, is delimited laterally by two flanges each comprising a groove or a rib opening in its face opposite the other flange,
• the shell has, on its underside, at least two lateral pads of the same curvature as the upper surface of the base, intended to bear on this surface, each pad having a rib or a groove on the side of its outer face, engaged in the groove or in the rib of the corresponding flange of the base,
• Means are provided for blocking the hull on the base, in different sliding positions of the skids of the hull on the upper face of the base. According to an embodiment:
• the base on the one hand and the shell on the other hand are made of synthetic material molded by a blowing technique
• the base has a curved central and longitudinal upper surface which, centered on an axis located above the base and oriented transversely to the latter, is delimited laterally by two flanges each having a groove opening into its opposite face on the other ledge,
• the shell has, on its underside, two lateral pads of the same curvature as the upper surface of the base, intended to bear on this surface, each pad having a rib projecting from its outer face, engaged in the groove of the rim base correspondent,
• Means are provided for blocking the hull on the base, in different sliding positions of the skids of the hull on the upper face of the base.
• a first interesting characteristic of this seat is that its main constituent elements: the base and the shell, integrate the means for mounting the shell on the base with adjustment of the inclination in the desired position.
• Another advantage is that the guide surface of the shell on the base is large, and that the bearing surfaces are arranged laterally, which is favorable, since providing the seat with excellent resistance to lateral stresses.
• the lower face of each groove of a flange of the base is formed by the upper surface of the base, while the lower surface of each rib of a shoe of the shell is constituted by the lower face of the shoe. . Therefore, the grooves of the edges of the base and the skids of the shell are obtained simply, and their contact surfaces are large, which is a guarantee of improvement in their resistance.
• the means for blocking the shell on the base consist, on the one hand, of transverse notches offset longitudinally with respect to each other and opening into the upper face of the edges of the base, and on the other hand by two longitudinal rods which, joined by a handle and arranged in the central space delimited by the two skids of the shell, each successively comprise a first transverse part forming an axis of articulation mounted in a bearing corresponding to the crossing of a skid of the hull, a forward return and a second transverse part forming a locking finger, intended to be engaged in a transverse notch of a flange of the base, the rods being subjected to the action of elastic means tending to tilt the handle down.
• the recess in the underside of the shell is thus used to accommodate the means for locking the shell on the base, as well as the actuating handle of these means.
• To adjust the angular position of the shell with respect to the base it suffices to move the handle upwards, against the action of the elastic means, to release the locking fingers from the transverse notches in which they have engaged.
• the shell can then slide freely vis-à-vis the base, into the new desired angular position, in which the operator releases the pressure exerted by the handle to achieve a new locking in this position.
• the elastic means associated with the locking rods are constituted by two springs in the form of cane beaks each mounted between the underside of the shell and a locking rod.
• Figure 1 is a side view
• Figure 2 is a cross-sectional view of its lower part along the line II-II of Figure 1
• Figure 3 is a perspective view on an enlarged scale of the locking device of the hull on the base.
• the car seat for children shown in the drawing comprises a base 2 intended to rest on a seat or seat of a motor vehicle and to be fixed on this seat, for example by straps not shown in the drawing.
• a shell 3 comprising, coming from molding by a blowing technique in one piece, a seat 4 and a back 5, the seat and the back having side edges 6 forming armrests, and ensuring holding the child's bust when installed in the seat.
• This shell is equipped, in a manner known per se, with a comfort padding for the child, as well as a harness for retaining the latter.
• the base 2 made of synthetic material and obtained by a blowing technique, comprises a curved central and longitudinal upper surface 7, this surface being centered on an axis located above the base. and oriented transversely to it.
• This base also comprises two lateral flanges 8 which form an integral part thereof, and which delimit the curved upper surface 7.
• a groove 9 In each flange 8 is formed a groove 9, the lower face of which is constituted by the upper surface 7 of the base.
• the shell 3 comprises, on its lower face, two lateral pads 12, of the same curvature as the upper surface 7 of the base, and intended to bear on this surface.
• Each shoe 12 has a rib 13 protruding from its outer face, engaged in the groove 9 of the corresponding flange 8 of the base.
• the lower surface 14 of each rib 13 of a shoe 12 is constituted by the lower face itself of the shoe.
• each flange 8 of the base 2 has transverse notches 15 distributed over its length, and opening into its upper face.
• the hull is equipped, at the central space 16 formed between the two pads 12, with a handle 17 mounted on the ends of two rigid longitudinal rods oriented from front to rear.
• These rods 18 comprise, at their rear end, a transverse part 19 facing outwards, passing through a shoe 12 forming, at this level, a bearing 20 allowing the rotation of the transverse part 19.
• This transverse part 19 is extended by a back 22 towards the front, itself extended by a transverse part 23 turned towards the outside, forming a locking finger intended to be engaged in a notch 15 opening into the upper face of a flange 8.
• the rods 18 are each subjected to the action of a spring 24 in the shape of a cane beak, tending to spread the rod from the bottom of the seat, that is to say to push the rod considered downwards.
• This action of the springs 24 results in the retention of the locking fingers 23 in the engaged position in notches 15 of the base.
• the user simply has to lift the handle 17 against the action of the springs 24, which results in the release of the fingers 23 out of the notches 15.
• the invention brings a great improvement to the existing technique by providing a car seat for children, of simple structure, the number of component parts of which is very limited, while having a practical character for the user, given the ease of adjusting the inclination of the shell, and having excellent stability, given the spacing of the contact surfaces between the shell and the base.
• the invention is not limited to the single embodiment of this child car seat, described above by way of example, on the contrary it embraces all variants.
• the general structures of the base and of the shell could be reversed, the lower face of the shell comprising a continuous surface with flanges provided with grooves and the upper face of the base comprising a discontinuous surface with side edges provided with ribs, without departing from the scope of the invention.
