Description

OBJECT OF THE INVENTION The aim of this invention application is to register a vehicle seat belt fastening device which incorporates noteworthy innovations and advantages with respect to the techniques used hitherto. More specifically, the invention proposes the development of a vehicle seat belt fastening device which, due to the particular arrangement thereof, allows for a simple, effective and safe fastening of a vehicle seat belt and, at the same time, in the event of an emergency and/or accident, allows for the usual strap of a vehicle seat belt and/or the windows of the same vehicle to be broken if the normal opening and closing mechanism of the same seat belt is locked and does not allow for a conventional opening thereof, the same being the case for the doors of the same vehicle, thereby allowing a user to be released and to exit the vehicle in the event of an emergency and/or accident. BACKGROUND OF THE INVENTION Seat belts intended for and used by the driver and other occupants of a vehicle are known in the current state of the art. Despite the very good safety features known and provided by said known seat belts, circumstances may occur in which during an emergency and/or accident, the opening and closing mechanism of the seat belt fails and is locked, unable to be opened, and furthermore, the doors of the same vehicle could be locked as well, also being unable to be opened. Accordingly, it could be that in the event of an accident an occupant of a vehicle is trapped inside the same after an accident or emergency for a period of time which may be decisive in saving the person's life. This circumstance can become especially dangerous in extreme situations for the user, such as the vehicle falling or sinking into water, a vehicle fire, etc., in which it is necessary for the user to quickly release the seat belt and immediately exit the vehicle. In other words, the seat belt can become a death trap for a person who is unable to release it. The present invention contributes to solving the present problem by allowing for a simple, effective and safe fastening of a vehicle seat belt and, at the same time, in the event of an emergency and/or accident, allowing for the usual strap of a vehicle seat belt and/or the windows of the same vehicle to be broken if the normal opening and closing mechanism of the same seat belt is locked and does not allow for a conventional opening thereof, the same being the case for the doors of the same vehicle, thereby allowing a user to be released and to exit the vehicle in the event of an emergency and/or accident. The document WO03/089278A1 discloses a seat belt fastening device according to the preamble of claim 1. DESCRIPTION OF THE INVENTION The present invention has been developed with the aim of providing a vehicle seat belt fastening device, said seat belt being equipped with a strap and a closing mechanism, said closing mechanism being simultaneously linked to the vehicle floor and also enabled to be linked in a sliding manner to the strap, the seat belt thus being suitable for holding said strap in relation to the closing mechanism, and therefore in relation to the vehicle floor, which comprises a tool that is enabled to be attached and removed in relation to said closing mechanism, said tool also being enabled to be manually manipulated, and to be manually attached and/or manually removed in the attachment and/or removal position thereof from the closing mechanism, said tool being provided with means for cutting the strap and/or with means for breaking the windows of the vehicle. According to the invention, the vehicle seat belt fastening device further comprises a first part and a second part, both of which are enabled to be comprised in the same closing mechanism, in which the first part is enabled to be linked in a sliding manner to the seat belt strap, and the second part is enabled to be comprised in the closing mechanism such that it is linked to the vehicle floor, the first part and the second part being mutually couplable, the first part remaining linked in a sliding manner to the strap and the same second part remaining linked to the vehicle floor, the first part, the second part and the tool being mutually enabled for a simultaneous insertion and/or passage of said tool through the first part and through the second part in the coupling of the latter two, the tool therefore being able to be attached to the closing mechanism by means of the insertion and/or passage thereof through the second part; the first part and the second part also being able to be attached to each other in the coupling thereof by means of the simultaneous insertion and/or passage of the tool. In the vehicle seat belt fastening device, the tool preferably has an extension by way of a pin enabled for the simultaneous insertion and/or passage thereof through the first part and the second part. In an alternative embodiment of the vehicle seat belt fastening device, the first part has a
