Abstract

The invention has as objet a signalling device in the case of the non-employing of the safety belt, formed of an infrared light flux source (SI), placed on the safety belt and of an electronic photocommanded switch (H), placed on the wheel or on the dashboard of the vehicle. The goal of the switch (H) is to supply a visual warning device (F) and an accoustic alarm (E), placed on the dashboard, and also to determine the feeding of the breakdown lights (L1, L2, L3, L4). In the case when it does not receive the infrared light flux from the infrared source (SI), which is fed by a contact (C) in the lock (IC) of the safety belt; (SI) generates an infrared light flux only as long as the safety belt is coupled in the lock and, therefore, the self locking key will keep the contact (C) closed.

Description

S I GNALL I NG DEV I CE I N CASE OF NON-EMPLOY I NG THE SAFETY-BELT

TECHNICAL FIELD

The invention refers to a device able to signal through turning on the damage lights or through other signals in case that the driver or the other passengers do not use the safety belt during the rolling.

BACKGROUND ART

There exist various devices (used for cars; which signal the lack of use of the safety belt by the passengers in the car. some or these devices are integrated in the structure of complex microelectronic systems of optical and acoustical report to drivers. These systems are Termed mainly of a microprocessor, a display device, a voice synthetiser and several transducers and sensors which are connected to the microprocessor access and which transmit to the system information about the state or the way of functioning of the car. In the specific case of safety belts the microelectronic system receives information from a sense, whose goal is to check whether the self-locking key of the safety belt is coupled in the lock. If the safety belts are not coupled and the driver wants to start the car, the microprocessor by means of the voice synthetiser or of the display device asks the passengers of the cat to couple in the safety belts. When this request is fulfilled., the engine can be started. These device presents the disadvantage that they allow the driver and the others no; to use the safety belts if they do not want to; they can only to couple in the safety belts behind their seats or can couple them in and then sit on them. DISCLOSURE DF INVENTION

According to our invention. the device removes the above mentioned drawbacks: it consists of a source of infrared light flux placed in the driver's safety belt, which is supplied through an electric contact places in the lock of the respective safety belt; in addition to this, there is also an electronic photocommanded switch which supervises the infrared light flux generated by the infrared source and which drives a relay which in its turn switches off a supply contact of an acoustic alarm and of a visual warning device on the dashboard. Thereafter, this relay operates another, which switches off the supply contact of the breakdown signals. Through the contact in the lock of the safety belt, which is switched off by the self-locking key of the safety bolt another relay is fed, which switches off a contact and a supply circuit of the starter.

BRIEF DESRIPTI0N OF DRAWINGS

Next, an example is given of the realisation of the invention in relation with the figures 1 and 2, which represent as follows: 1. T he fundamental circuit of the device

2. The place of the source of the infrared light flux on the safety belt

BEST MODE FOR CARRYING OUT THE INVENTION

The device is made of a source of infrared light flux SI placed on the safety belt of the driver and supplied through a contact C i n the lock device IC of the safety belt. The contact C is operated by the self locking key of the safety belt in the respective device arc. therefore closed only when the safety pelt is coupled. Through the contact C, a relay R is fed, which switches off a contact C1 on the supply circuit of the electric starter D . I n ca se that the contact D is not switched off, C1 will remain on and the c ar engine can riot be started through the starter D. In the case when the contact C switches off the source of the infrared light flux, SI will be supplied and the infrared light flux generated by the source will be received by the photosensitive element of the electronic photocommanded switch H placed either on the central part of the wheel or on the dashboard. (As long as the electronic photocommanded switch H receives the infrared light flux, it fulfils a similar role with that of an open switch, but as soon as the infrared light flux is interrupted the electronic switch H changes its function into that of a closed switch. Thus, it feeds a relay R2 with the nccessary time delay to prevent random interruptions of the infrared light flux. In its turn, RP closes a contact C2, which will supply an acoustic alarm E and an optical signal F on the dashboard and at the same time another relay R3, which feeds the breakdown lights of the car L1, L2 , L3, L4. In addition to this, the relay R3 is also meant to stop the feeding of the acoustic alarm E and the optical signal F on the dashboard when the breakdown lights are connected by the driver through a switch B.On the other hand, then relay R3 starts with a time delay, in order to give the driver time to couple the safety belt, after he has received the acoustic and the optical signals. The electronic photocommandcd switch H is supplied through a feeding contact A, which feeds the electric accessories of the car. This latter contact is operated by the switching key car; the contact A is still closed at the moment when the switching key puts on the contact CD through which is fed the starter D.

INDUSTRIAL APPLICABILITY

The main advantage of this device is that it Permanently checks whether the passengers have coupled on the safety belt. This thing is carried out with the help of the source of infra-red light flux and of the electronic photocommanded switch. In the case when the safety belt is not coupled or is coupled in a wrong way, the infrared light flux generated by the source will not arrive to the photocommanded switch and this will determine the lightening of the breakdown lights or will determine the Start of other devices which will force the driver and the others to use correctly the safety pelts.

Claims

PATENT CLAIMS

1) signalling device in case of the non-employing of the safety belt is formed by a source of infrared light flux (SI) placed on the safety belt, supervised by an electronic photocommanded switch (H), placed on the central part of the wheel or on the dashboard, which operates, in its turn, on a rel ay (R2). The relay (R2), commands an acoustic alarm (E) and an optical signal (F), through the contact (C2).

2) The device, according to the claim 1), contains another relay (R3). which stops the feeding of the acoustic alarm. (E ) and the optical signal (F) when the Breakdown lights (L1, L2, L3, L4) are connected by the driver.
