- a safety seat 1 for receiving an occupant and in particular a child, forming a high chair.
- This high chair comprises a seat 3a and a backrest 3b which are held at a desired distance from the ground by four feet 5.
- this high chair comprises means which are able on the one hand to control the good maintenance of an occupant on it by means of a harness and on the other hand to detect the events which constitute the first fruits a fall of the high chair so as to allow intervention to prevent this fall.
- the means for detecting the premices of a fall will be exerted on two levels, on the one hand, at the level of a detection of a disturbance manifested by the occupant of the high chair, and, on the other hand, at the level of an inclination of the latter which usually follows the agitation and which precedes the fall. It is thus understood that it is advantageous to measure a level of agitation which, combined with the absence of a change of inclination detection, makes it possible to trigger a warning in advance without waiting for the actual tilting of the high chair to begin.
- the seat 1 comprises a harness which mainly comprises a first central strap 7, called a crotch strap, which at one of its ends has a locking loop 9, and which through the seat 3a through an orifice 11 to be fixed, at its other end, to the upper part of the back of the backrest 3b, at a point of attachment 13 with the interposition of an elastic return strap 15.

- the holding harness also comprises two side straps 17a and 17b which are arranged symmetrically with respect to the backrest 3b. The ends of each of these two straps 17a and 17b through the upper part of the backrest 3b and the seat 3a to attach to the back of these two elements. Moreover these two straps are joined on a hook 19 adapted to cooperate with complementary means of the locking loop 9, so as to be able to lock in it in the immobilization position of an occupant on the high chair 1, as shown in FIG. 2.
- a sensor 21 adapted to detect the presence of the locking loop 9 when the latter is applied against the orifice 11 under the effect of traction applied to it by the strap elastic return 15, as shown in Figure 1.
- the presence sensor 21 of the locking loop 9 is connected to an electronic logic disposed in a housing 23.
- This electronic logic comprises a power supply battery 23a, in particular a lithium battery, which supplies a microcontroller or a microprocessor 23b which is in connection, by wired connection means 25, with the loop sensor 21.
- a switch 23c controls the power of the device and a buzzer 23d controlled by the microcontroller 23b can report any critical situation.
- This housing 23 may be placed for example under the seat 3a of the high chair, substantially in the center thereof, so as to be out of range of
- the safety seat 1 operates as described below.
- the harness of the high chair 1 is in the position shown in FIG. 1, that is to say that the elastic return strap 15 applies the locking loop 9 against the orifice 11 and that the switch 23c is in the open position, so that the control electronics contained in the housing 23 is not activated and the alarm is therefore inoperative.
- the user of the high chair deposits the occupant, for example a child, on it and loops the harness by inserting the hooks 19 in the locking loop 9. To do this it exerts a pull on the strap of The user activates the control electronics by switching the switch 23c to the "on" position.
- the Microcontroller 23b can then acknowledge the activation by controlling the generation of an audible signal via the buzzer 23d to the attention of the user who has therefore confirmed that the system is operational.
- the elastic return strap 15 due to the tensile force it exerts on the locking loop 9, brings it back against the orifice 11, so within reception range of the loop presence sensor 21, and the latter then sends the microcontroller 23b a signal.
- the microcontroller 23b Upon receipt, the microcontroller 23b then triggers, for the attention of the user, an alarm by means of the buzzer 23d. The user is thus warned that the child has partially dislodged and can intervene.
- the means for detecting the presence of the locking loop 9 can be of very different types.
- they may for example be constituted by a passive antenna of the "RFID tag” type which is arranged on the locking loop 9 and which will be detected by appropriate means complementary to the sensor 21. They may also consist of a magnet or a magnetized portion of the loop that will close an electrical circuit via an ILS-type device or a Hall effect sensor of the sensor 21.
- the control device comprises a detector 20 which is located in the extension of a housing 22 and comprises a flexible and deformable tongue 24, for example a compound polyamide, polyether, polyester, isocyanate, etc.
- This tongue has sufficient rigidity so that, in the absence of stress, it is able to resume its rectilinear shape as shown in FIG.
- the housing 22 and the detector 20 comprise two accelerometers 24a and 24b which are provided, in a known manner, with an inclinometer function which will be used in the present case.
- the first inclinometer 24a is disposed in the housing 22 and is connected to a microcontroller 23b.
- the second inclinometer 24b is arranged at the free end of the tongue 24 and is connected to the microcontroller 23b by a wired connection 28.
- the microcontroller 23b is able to easily determine the value f of the deflection of the detector, and therefore that of the lateral holding strap 17a, 17b on which it is mounted, by the simple difference of the values delivered by the two inclinometers.
- the microcontroller 23b compares this value f_ with a threshold value fs_ and if it is higher, it deduces that the curvature is sufficient for the child to be well strapped and, conversely, if it is inferior, he deduces that the The child is detached and gives a warning signal to the user.
- the high chair 1 is provided with means for detecting the presence of a child thereon, these means being in relation with the microcontroller 23b.
- the detection means and the communication means with the microcontroller 23b can also be of very different types. These means may, without limitation, be for example mechanical type such as in particular a pressure sensor or weight, electronic type such as in particular photocell, strain gauge or capacitive type.
- Such a sensor which is for example arranged in a cushion placed on the seat 3a of the high chair, may consist of a plate 27 on which a feeler 29 is rotatably mounted around an axis 31 and which, in the absence of stress, is positioned in a high position by a compression spring 33.
- a switch 35 is arranged on the plate 27 so that when the probe 29 is in the down position, it is activated.
- the sensor consists of a housing 37a enclosing a piezo crystal cartridge 37b and whose anterior portion is provided with a probe 37c which, when no stress is exerted on it, protrudes from the upper part of the housing 37a.
- This feeler 37c is mechanically connected to a rigid transmission element 37d with the piezo cartridge 37b, so that when a bearing force is exerted on it in the direction of the arrow A in FIG. piezo 37b is compressed and generates a pulse which is communicated via communication means, in particular of wired type, to the microcontroller 23b.
- communication means in particular of wired type
- a presence detector of the child by means of a capacitive antenna arranged in a housing that can be positioned under the seat 3a of the high chair as well as the housing 23 mentioned. previously and shown in Figure 1.
- Such a variant of the invention is particularly interesting in that it does not require for its implementation any modification of the high chair.
- This capacitive antenna will also be able to detect the presence of the child through the material of the seat 3a that it is particularly wood or a synthetic material.
- the capacitive antenna measurement can be done remotely and, depending on the setting of the parameters thereof, it will be able to diagnose, on the one hand the presence or absence of a child in the high chair and of on the other hand smaller variations corresponding to the fact that the child lifts slightly, for example by one centimeter, while its presence is detected, which will participate in the means implemented for the detection of a agitation as explained below.
- a capacitive antenna is a means for detecting and measuring a level of agitation of the occupant of the seat.
- the high chair 1 is thus equipped with means for detecting agitation.
- these means for detecting agitation of the occupant of the high chair there is, for example under the seat 3a thereof, particularly in the housing 23, at least one accelerometer 34, three-dimensional type, which is connected to the microcontroller 23b, and is able to detect any inadvertent movement of the high chair, that is to say any sudden movement resulting in significant agitation of the child who, if she continued, could cause the tilting outright of the high chair.
- the accelerometer 34 is arranged in such a way that, as shown in FIG. 1, its axis x is positioned towards the front of the high chair 1, its axis y is positioned transversely thereto and its axis z is positioned vertically.
- the stirring detecting means may comprise adjustment means making it possible, in particular during initialization, to correct by software a possible positioning error.
- Detection of the agitation can be carried out continuously with a measurement frequency of the order, for example 100 times per second.
- the microcontroller 23b performs a series of N measurements of the acceleration, for example of the order of 10 to
- microcontroller 23b realizes an average ⁇ ⁇ , Yym, Yzm of these different measurements and we have:
- Yxm (Yx1 + Yx2 + ... + Yxn) / N
- Yym (Yyl + Yy2 + ... + Yyn) / N
- the mean deviation that is to say the average of the absolute value of the deviation of each of these measurements with this average value.
- This value of the average deviation is thus representative of the movements made by the occupant of the high chair 1 along each of the three axes x, y, z.
- These characteristic values of the level of agitation along the three axes x, y, z are thus interesting in that they enable the microcontroller 23b, via appropriate management software, to be able to take into account very dangerous situations. variety.
- the mean difference will be of the order of the measurement noise of the accelerometer 34, that is to say of the order of + / 1 to 2 bits. that is, the least significant bits of the measurement contained in the registers of the accelerometer 34 which constitutes a first threshold value.
- the microcontroller 23b detects a higher threshold value which corresponds to a state of the high chair 1 not immobile and then triggers the signaling means.
- a higher threshold will allow microcontroller 23b to make a difference between a normal level of agitation corresponding to the presence of an occupant in the high chair and a much higher level of alarming agitation.
- the present invention makes it possible to detect, for example, a situation in which a person, and in particular a child, moves the high chair with a child already present without such a displacement modifying his inclination since, in such a situation, the value of the difference mean along the z axis, the value ⁇ ⁇ , will be weak or non-existent and that the values ⁇ ⁇ and 5 y will have significant values characteristic of the movement of the high chair in a plane.
- the microcontroller 23b will favor a lateral movement.
- means for analyzing the N samples of the chair will be used. Measurement done more accurate. Instead of a simple determination of a mean difference, we will use a method, well known in itself, namely the so-called least squares method, to define the linear function that approaches the physical measurement of the N samples the most:
- the distance to the linear regression line will be the measurement of the agitation along one of the axes
- the slope of the line of linear regression will characterize if it is weak a simple translation, if the slope is strong a significant growth / decrease of the successive values diagnosing the combination of a stirring and a rotation leading to a monotonous variation increasing / decreasing accelerations values.
- the microcontroller 23b When agitation above a threshold level is detected the microcontroller 23b then triggers an alarm via its warning means.
- the alert can be relayed by a local signal by an audible and / or visual signal sent on a remote RF receiver, or a smart smartphone-like terminal as well as on any device equipped with a bluetooth technology, especially low energy type, or any other standard of transmission of information, including a stereo, a computer, TV, stand-alone speaker etc.
- transponder in certain contexts of collective surveillance, for example maternal kindergarten, it is possible to implement a solution by transponder or similar antenna anti-theft systems.
- the transponder In the absence of an alert, the transponder is enclosed in a metallized housing acting as a Faraday cage. In case alarm or alarm one of the faces of the housing is physically open allowing the detection of the transponder.
- the planar antenna solution is also possible, the antenna being opposite or not a metallized case preventing detection of the antenna similar to the anti-theft systems.
- the present invention also takes into account the situation in which the high chair begins to tilt and provides means capable of detecting a variation in the inclination thereof.
- an inclinometer 36 disposed on the seat for example under the seat 3a thereof, particularly in the housing 23, as shown in FIG. 4, which will send the microcontroller 23b the value I_ of inclination instant seat.
- the microcontroller 23b Upon receipt, the microcontroller 23b will compare this value I_ to a reference limit value _I_i and if the latter is reached it will then trigger an alarm procedure.
- the invention it is also possible to provide, in particular for teaching purposes, to implement means capable of emitting an early warning, for example in the form of an ultrasound emission, which only the child can hear, and this before issuing the warning intended to alert the user. Then, if the agitation of the occupant becomes such that it causes an inclination of the high chair, it will then be detected by one inclinometer and sent to the microcontroller 23b which, via the warning means, then emit another characteristic signal of seat inclination. The user will thus be warned of the pre-eminence of a serious and imminent risk of falling from the high chair.
- an early warning for example in the form of an ultrasound emission
- the inclinometer function can be provided, in known manner, by an accelerometer and in particular a three-axis accelerometer or an inclinometer of the type using one or more gyroscopes.
- the safety seat according to the invention may comprise analysis means constituted in particular by electronic means comprising for example logic gates or means consisting of a microcontroller that will perform this type of analysis by software means.
- the analysis means may, by way of example, detect various configurations that present a danger and in particular the following cases:
- a child whose high chair is placed near a table and who pushes it away from the table at the risk of tipping it is identified by the detection of a level of agitation mainly along the longitudinal axis y and variations of angle of inclination of the high chair by the accelerometers,
- a child who is poorly strapped or who has detached and is trying to get out of the high chair at risk of tipping is diagnosed by the detection of a level of agitation and the detection of incorrect strapping, including at the level of the shoulder by the means of detecting a correct strap as described with reference to FIGS. 6 to 8.
- a child who is poorly strapped and who is at risk of slipping and strangulation is diagnosed by the detection of a level of agitation and the detection of incorrect straps, especially at the level of the crotch strap, by the children. detection means of the type described with reference to FIGS. 1 to 4.
