Description

Simulated occupation device for airbags vehicular.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a device simulated occupancy for vehicle airbags, intended for simulate a permanent occupation of, for example, the seat of the co-pilot of a vehicle.

The object of the invention is to transmit to conventional vehicle seat occupancy sensor module, in the disconnected position, the simulated occupation of said seat, in order that in case of an accident communicate to the system of airbag that seat is occupied and occur accordingly the activation of the airbags corresponding to such a seat, regardless of whether or not there may be a failure in the sensor circuit

Background of the invention

As is known, the airbag systems of vehicles include sensors that detect if the circuit is is in proper operating situation to transmit the appropriate activation orders to the airbags in case of accident, so that in case of detecting system failure, sends a warning or alarm signal to the control panel of the dashboard, indicating to the driver a possible system breakdown of airbags.

Now, it is very common to share the warning or alarm signal on the control panel of certain vehicles, indicating airbag system failure corresponding to a certain seat, with which the user of the vehicle goes to the corresponding repair shop to have your system checked and correct the anomaly.

As it is evident, the location and repair of this type of breakdown or anomalies is carried out by qualified personnel, and taking into account that a large number of the times that the workshop is visited (before the indication of failure of the airbag system), Due to a small connection failure or other easily rectifiable circumstance, there is no doubt that for the user it is a significant economic cost to have to attend the workshop and it is the qualified or specialized staff who is responsible for detecting the anomaly, and if necessary, repair the
same.

Well, considering that in the greater part of the occasions it is necessary to disassemble door panels, seats, etc., to detect the fault indicated on the panel control, there is no doubt that the economic cost of User is sometimes very important, regardless of inconveniences that the user has to carry and Leave your vehicle in the workshop.

However, documents are known in which describe systems to inhibit the error performance of means of protection and / or to detect the presence of an occupant in a particular seat of a vehicle, as well as to control the activation of the means of protection such as vehicle airbags.

Specifically, the European patent can be cited  2186051 in which an apparatus for detecting the presence of an occupant in a vehicle; European patent 2209009 in which a system is described to control the activation of a airbag in a vehicle; European patent 2157358 in which describes an arrangement for inhibition of activations by error of vehicle occupant protection systems; the European patent 2180516 describing a detection sensor of presence for intelligent airbag systems; The patent Spanish ES2172450 describing a control device of presence of people in the seat of a motor vehicle, and the European patent 2294440 describing a detection system of the presence of a passenger in a vehicle.

In all the cited patents, the objective that pursued is either inhibit the performance of for example a airbag in those cases where there is a failure in the electronic circuit, or ensure that the seat of a vehicle is busy, regardless of whether the sensor is right or wrong conventional associated with the airbag system, in order to ensure the Airbag activation in case of accident.

Now, in none of the cases is described a sensor with the characteristics and purpose or benefits that presents the one that is intended to be protected in the application of the utility that concerns us.

Description of the invention

The device of the invention is provided to establish a connection with the sensor module of the system airbag from the seat of a vehicle, after disconnecting it regarding the electronic system in charge of signaling optically and / or acoustically the failure or error status of the system Airbag corresponding to that seat.

The device in question is constituted by an electrical circuit formed by a resistor and a diode connected in series, with a plug that can be universal to allow its implantation in any vehicle, regardless of the model and / or brand of it.

Therefore, it is a device seat occupancy simulation sensor, intended for transmit to the occupancy sensor module (in operation) the simulated seat occupation, which in the event of an accident communicates to the airbag system that the seat is occupied so that the airbags in question are activated.

The device may be made depending of the type of car and its brand, although it can be complemented with a variety of pins, or with a universal plug for connection with the car electronic system connector as well as with different resistors in order to simulate a seat occupancy

The connection between the electronic system and the device can also be done through a connection direct, disregarding in that case the specific plug for Each car

Based on all of the above, the device of the invention offers the following features innovative:

-

Simulates permanent occupation

-

He airbag always works, preventing disconnection when there is a fault between the sensor circuit, always being activated regardless of the movements detected by the sensors

-

Possibility of supplying plug universal connection, allowing installation or assembly in Any vehicle regardless of brand.

-

They look reduced repair costs, since having to go is avoided to the workshop and review why those possible indications of Failure or errors that normally occur in vehicles.

-

He device always allows the connection of the airbag system, without be conditioned to any motion detector to activate, inhibiting the fault signal on the vehicle control panel, avoiding taking it to a workshop for review, with the consequent cost savings of repair.

Brief description of the drawings

To complement the description that then it will be done and are the object of helping a better understanding of the features of the invention, accompanies the present descriptive report, forming an integral part of the same, a set of drawings based on which more will be understood easily innovations and advantages of the device of the invention.

Figure 1.- Shows the scheme corresponding to  electrical circuit of simulated occupancy device for vehicle airbag made in accordance with the purpose of the invention.

Figure 2.- Shows the scheme corresponding to the practical application of the device itself represented in the previous figure.

Preferred Embodiment of the Invention

As you can see in the referred figures, the simulated occupation device object of the invention, provided specifically to establish a simulated seat occupation corresponding to a vehicle, so that in case of accident it activate the airbags attached to said seat, it is constituted by a circuit formed by an electrical resistor 1 and a diode 2 connected in series, with corresponding power electric 3.

Said arrangement determines a sensor module 4 equipped with a connection plug 7, which can be universal for its connection to the connector 5 of the sensor module 6 of occupation of a seat, when the plug that has been previously disconnected established the power supply of that sensor module 4 of seat occupancy

In figure 2, it is shown as the sensor module 6 of the vehicle seat presents its free connector 5, that is, no power supply from the corresponding airbag system to that seat, that connector 5 being destined to receive the connection of pin 7 corresponding to the sensor that constitutes the simulated seat occupation device, so that in case of accident and / or crash of the vehicle, be notified that that seat is busy and occurs, through the corresponding system, the activation of the airbags associated with it.
