Definitions

• the invention relates to the technical sector of automotive safety devices for children, usable at the rear and / or front of vehicles for individuals.
• automotive child safety device is limited to the lower weight categories, ie groups 0, 0+ and 1, devices respectively for children from 0 to 10 kg, from 0 to 13 kg and from 9 at 18 kg.
• the invention relates, more specifically, to devices made up of a shell and a carrying handle, offering multiple functions, such as carrying out of the vehicle or using it in a sun lounger.
• the device is directly held by the belt, the correct positioning of which is mandatory for effective retention of the device. This means that, on a daily gesture, the user must exercise special care to ensure the safety of his child.
• the obligatory points of passage of the strap are not always easily accessible, thus requiring some efforts to install the device. In conclusion, in addition to the fact that repetition constitutes a constraint, it can also represent a danger.
• the devices provided with a base offer, for their part, better reliability of the installation, knowing that it should only be carried out the first time the device is used.
• the practical aspect is also supposed to be improved thanks to the base, since the installation is then limited to a simple nesting of the two elements one inside the other.
• the space for entering the device into the vehicle is limited by the presence of the base and necessarily requires the handle to be folded down before entering the vehicle.
• the operation then consists in positioning, with precision and at arm's length, a device weighing ten kilos, perpendicular to the seat of the vehicle, while this device no longer presents any real possibility of grasping, the handle having been previously folded down to reduce the size of the device.
• the invention relates to a child safety device, adaptable to a vehicle, comprising:
• the vertical locking means comprise, on one of the support or support surfaces, an anchoring piece provided with at least one locking branch, and on the other of the support surfaces or support, an opening opening into a cavity and having a passage section, said opening passage section making it possible to insert the locking branch through the opening, according to the engagement position, and then bringing the portable element into the locked position, by virtue of a relative rotation of the anchor relative to the opening.

• Fig. 5 illustrates the locking operation in rotation of the portable element.
• the fig. 1 shows, on a reduced scale, the security device 1 according to a non-limiting mode of the invention, this device comprising a portable element 2 placed on a base 3.
• the portable element 2 provides reception and protection functions for the child and includes either a single element constituting the seat and the back of the device, or several elements constituting, respectively, the seat, the backrest, the headrest ...
• the portable element 2 comprises a shell intended to receive a seat for a child.
• this portable element 2 is relatively rigid and light, in order to meet the requirements of standards and the convenience expected by the consumer. This is why their constitution is mainly based on:
• polyurethanes which can be reinforced by tubular, in particular metallic, reinforcements.
• the portable element 2 has a tilting handle 4 which provides, in particular, a carrying function.
• the design and ergonomics of the handle vary depending on the device. Depending on the model, the handle offers displacement parallel to the body, perpendicular to the body or both possibilities.
• the base of the portable element 2 can also have rails ensuring a swing function.
• the base 3 is fixed to the vehicle seat by any suitable means, in particular using a seat belt or a strap.
• the base 3 includes points for passing the safety belt, such as slides 5 and 6, a baffle 7 comprising a slide provided with a closure means 8.
• the slides 5 and 6 are, in agreement with the requirements of the European standard in force, located at least 150 mm from a point constituting the intersection of the backrest and seat of the vehicle seat on which the base 3 is fixed.
• the passage of the seat belt through the baffle 7 ensures a deflection of the path of the latter, making it possible to free the space necessary for the rotation of the portable element 2 on the base 3.
• the base can also include , a part 9 in the shape of a "U", intended to limit the risks of deformation of the portable element 2, the seat-back angle of which could be open.
• the part 9 in the shape of a "U” is directly in contact with the back of the portable element 2, which makes it possible to block any movement of the back relative to the base towards the front of the vehicle.
• the shackle 4 In preparation for installation in the vehicle, the shackle 4 can be folded down, from its vertical position towards the back of the portable element 2, in an intermediate position at around 45 °, which makes it possible to considerably reduce the bulk. of the portable element 2 and, thus, facilitate its entry into the vehicle.
• the first step in the installation consists in positioning or stacking the portable element 2 on the base 3.
• the portable element 2 and the base 3 are equipped with means allowing the centering and positioning of the portable element 2 on the base 3.
• the first installation step is simplified by these means, ensuring a centering and instant positioning function of the portable element 2, without position or locking search, as is the case for certain devices of the prior art.
• the centering and positioning means comprise, on the support surface 11, a cone or, preferably, a centralizing truncated cone 12, cooperating with the bearing surface 13 disposed under the portable element 2.
• This positioning step is therefore carried out simply and without blind search for the appropriate position, thanks to the cone or the truncated cone 12, located on the base 3, which allows automatic centering of the portable element 2 at the intended position. , i.e. the position of engagement.
• the support surface 11 and the support surface 13 have shapes having a symmetry of revolution with respect to an axis of rotation 14 of the portable element 2 with respect to the base 3. This makes it possible to obtain one of the characteristics of the invention which resides in the pivoting or rotation of the portable element 2 relative to the base 3.
• This pivoting characteristic allows, during the first installation step, to position the portable element 2 on the base 3, so that the portable element 2 is in a different position relative to a transport position , the latter being obtained by simple pivoting or rotation of the portable element 2.
• the engagement position corresponds to a position of the portable element 2 relative to the base 3 for which the child is arranged pe endicularly to a driving direction of the vehicle or parallel to a seat of said vehicle.
• this arrangement corresponds to a perpendicular arrangement of the portable element 2 relative to the base 3, obtained during the first step of installing the portable element 2 in the vehicle.
• This first installation step is carried out simply, since the portable element 2 is generally placed inside the vehicle, lengthwise, which allows a reduced bulk. This position then allows the adult to control the installation of the child in the hull and, if necessary, to replace it with ease or to easily adjust the harness, since the child and the hull are facing to the adult and not perpendicular as it is the case commonly, in particular for devices not having this pivoting characteristic.
• the adult can pivot the portable element 2 on the base 3 and lock it relative to the base 3, which constitutes a second installation step.
• the locking of the portable element 2, with respect to the base 3, constitutes a characteristic of the invention which is ensured, initially, with respect to a substantially vertical direction, by means of vertical locking.
• the vertical locking means comprise, on one side, an anchoring part 15 provided with at least one locking branch
• the passage section of the opening 17 allows, firstly, to insert the locking branch 16 through the opening 17, according to the position of engagement and, secondly, to bring the element portable 2 in the locking position, by virtue of a relative rotation of the anchoring part 15 relative to the opening 17.
• the anchoring part 15 has the shape of a "T", the upper part of which constitutes two locking branches 16.
• the anchoring part 15 is arranged on the support surface 11, in particular on the truncated cone 12, and an opening 17 is provided on the bearing surface 13 so as to receive said anchoring part 15 when the portable element 2 is in the engagement position.
• the anchoring part 15, inserted in the opening 17 of the bearing surface 13 of the portable element maintains said element portable 2 plated on the base 3.
• the vertical locking position corresponds, in turn, to a position of the portable element 2 relative to the base 3 for which the child is disposed parallel to a driving direction of the vehicle or perpendicular to a bench of said vehicle.
• this arrangement corresponds to a parallel arrangement of the portable element 2 relative to the base 3, obtained during the second installation step.
• the means for vertical locking of the portable element 2 relative to the base 3 further comprises at least one stop 18, disposed on the portable element, and at least one tab 19, arranged on the base, the stop 18 and the tab 19 being arranged so that the stop 18 comes to be inserted under the tab 19 during the rotation of the portable element 2 relative to the base 3 in the locking position.
• the upper face of the stop 18 comes into contact with the lower face of the tab 19, so as to lock and vertically wedge the portable element 2 relative to the base 3.
• the stop 18 and the tab 19 are, respectively, arranged on the portable element 2 and on the base 3, so that the stop 18 comes to be inserted under the tab 19 when the portable element 2 is arranged parallel to the base 3, that is to say when it has undergone a rotation of approximately 90 ° relative to an engagement position, corresponding to an arrangement of the portable element 2 perpendicular to the base 3.
• the stop 18 is added to the anchoring part 15 for the vertical blocking, or in translation, of the portable element 2.
• These two points constitute an effective and sufficient attachment of the portable element 2 compared to the base 3, guaranteeing the solidarity of these two elements in the event of an accident.
• the means constituted by the stop 18 and the tab 19 make it possible to reinforce the vertical locking of the portable element 2 relative to the base 3.
• the disassembly of the portable element 2 can then only be carried out by a reverse rotation movement and not by a vertical translation.
• the advantage of the rotary lock according to the invention lies in the elimination of the jerk often necessary on current devices for actuating a lock. Indeed, this sudden movement has the disadvantage of shaking the child and, if necessary, of waking him.
• the vertical locking is effective from the start of the rotation of the portable element 2 relative to the base 1.
• a third step in the installation consists in locking the portable element 2 in rotation relative to the base 3.
• the locking in rotation of the portable element 2 is ensured by a rearward inclination of the tilting handle 4, on either side of bosses located on the base 3 .
• the tilting handle 4 is generally fixed by two attachment points, on either side of the portable element 2, so as to provide a movement parallel to the child's body and around an axis passing through these two attachment points. Locking in rotation of the portable element 2 with respect to the base 3 is therefore ensured by the tilting handle 4, which the adult inclines backwards or decreases horizontally, when the rotation is effective, that is to say when the portable element 2 is in the locked position. The handle 4 then presses against the bosses 20 and thus condemns the rotation of the portable element 2.
• the portable element 2 is provided with two lateral handles 22 to ensure easy transport, with a studied grip, even when the handle is inclined.
• the tilting handle 4 can be folded down, without the portage being penalized, since the handles 22 then take over from the tilting handle 4.
