Definitions

  • This patent relates to safety devices applicable to motor vehicles, and in particular to a new safety device applicable to motor vehicles to signal the presence of a child sitting on a child car seat.
  • Older children are able to unlatch their seat belts, open the car door, or draw attention to themselves with gestures and shouts.
  • the prior art contains safety devices to alert the driver who leaves a car that there is a child still secured inside the car.
  • Some safety devices include a belt or strap to hook between the child's seat and the vehicle's key or to hook between the driver's headrest and the driver's door lock handle. These devices have been found to be more damaging and dangerous to the driver than useful for the child's safety.
  • Some safety devices use the car's power, usually from the cigarette lighter socket, to be powered. These devices are constrained to the car's power supply and are not operational if a person, driver or other passenger, removes the plug from the cigarette lighter socket, for example, to plug in another device that needs the power supply.
  • Some devices are connected with a receiver inserted in the car's ignition key. These devices have the drawback that the receiver battery may be discharged when the receiver should alert the driver, resulting in ineffective devices.
  • One object of the new device is to eliminate the chances of unintentionally leaving a child alone in a car.
  • Another object of the new device is for it to operate safely, independently of the vehicle's power supply.
  • a further object of the new device is for it to operate safely without requiring transmitters and/or receivers.
  • Yet another object of the new device is for it to safely activate the signal only if there is a child sitting on the child seat and all other passengers leave the car.
  • Still another object of the new device is to intervene, in an extreme situation, on the motor vehicle, breaking a window, so as to enable the hot air inside the passenger compartment to leave the vehicle.
  • Another object of the new device is to intervene, in an extreme situation, on the motor vehicle, in order to allow a quicker and more effective intervention by any person to remove the child from the locked motor vehicle.
  • the new device applicable to a motor vehicle to signal the presence of a child sitting in a car seat which comprises a management and control circuit, at least one battery, at least one sensor to detect the presence of a driver and/or passenger, at least one child safety belt closure sensor, at least one electro- acoustic alarm device, an indicator light to indicate that the device is on, at least one device to break at least one window, at least one temperature sensor, at least one timer.
  • the child safety belt closure sensor subsequently called the child belt sensor, is comprised of a mechanism or element designed to electrically signal the properly latched status of the seat belt suited to secure the child in the child seat.
  • This child belt sensor is comprised of an element or mechanism able to close an electrical contact, such as a magnetic contact, a microswitch, a two- terminal metal element suited to close the circuit between two electrical contacts of a bipolar cable or, preferably, a REED switch.
  • an electrical contact such as a magnetic contact, a microswitch, a two- terminal metal element suited to close the circuit between two electrical contacts of a bipolar cable or, preferably, a REED switch.
  • the driver's and/or passenger's presence sensor is comprised of a mechanism or element to indicate the presence of a person sitting in the driver's seat or in the front passenger seat.
  • This adult seat sensor is comprised of an element or mechanism to detect pressure on the seat on which it is placed, or of an element or mechanism to detect the fastening of a seat belt and is preferably comprised of a pushbutton designed to be enabled by the pressure exerted by the passenger's weight suited to close an electrical contact or a magnetic contact, a microswitch, or a REED switch inserted in the two parts, locking buckle and latch plate, on each of the seat belts for the front seats.
  • the electro-acoustic alarm device consists of any element or device, typically an alarm or buzzer, suited to emit a sound when it is electrically powered.
  • the power on indicator light is comprised of a device to optically signal that the new alarm device to signal the presence of a child sitting in a child safety seat is on and operating properly.
  • this power on indicator light is comprised of a LED or similar element.
  • the temperature sensor comprises a sensor suited to close an electrical contact when the temperature exceeds a predetermined value.
  • the timer comprises a device suited to wait a predetermined period time from the initiation of an electrical signal and suited to close an electrical contact when that predetermined time has elapsed.
  • the window breaking device consists of a casing that can be applied in proximity to or in correspondence with a motor vehicle window, containing a mass, an elastic projection element, and an electromechanical release mechanism.
  • This electromechanical release mechanism is electrically connected to the temperature sensor and timer.

  • the electromechanical release mechanism, the mass, and the elastic projection element are arranged in the casing so that:
  • the elastic projection element is comprised between the inner wall of the casing and the non-pointed end of the mass

  • the window breaking device when it receives electrical power from the timer and temperature sensor, activates the electromechanical release mechanism allowing the elastic projection element to project the mass toward the window causing it to break.
  • the control and management circuit consists of an electrical and/or electronic circuit connected to all other parts of the new alarm device to signal the presence of a child sitting on the child seat by means of electrical cables.
  • the battery consists of at least one rechargeable battery, suited to supply all the electrical parts of the new alarm device to signal the presence of a child sitting on the child seat.
  • a cable with a plug suited for the cigarette lighter socket is provided to enable the battery to be recharged. It is preferable that this plug suited for the cigarette lighter socket have a serial socket, so that another device can be supplied with power even while the battery of the new device is being recharged.
  • a hold button is provided so as to temporarily change the sounding of the electro-acoustic signal.
  • This hold button can be useful when, for example, the adult stops the car at a gas station and gets out of the vehicle to refuel. In this case, the adult, exiting the vehicle, presses the hold button and the electro-acoustic signal, instead of issuing an alarm, will provide a relaxing melody for the child, and a reminder for the adult, for a pre-established amount of time. In fact, after that time, if the adult does not return to the motor vehicle, the electro-acoustic alarm device emits the alarm signal.

  • this first (4.1) and second (4.2) part of the child safety belt sensor (4.1, 4.2) are suited to close an electrical contact connected to the control and management circuit (1) only when the seat belt (Bl, B2) of the child seat (B3) is completely and properly latched.
  • the child safety belt sensor (4.1, 4.2) comprises a switch to switch the new child alarm device to signal a child sitting on the child car seat on and off.
  • the control and management circuit (1) is suitably enclosed in a casing or container, together with the battery (2), and is housed in a suitable position.
  • the control and management circuit (1), together with the battery (2) are located beneath the driver's seat (A), but they may be placed in another appropriate position.
  • the adult seat sensor (3a, 3b; 3al, 3bl) is comprised of a mechanism or element to indicate the presence of a person sitting on the driver's seat (A) or on the front passenger seat.
