As can be seen in the fi gures, the perfected vehicle seat belt is of the three-point type with a shoulder strap portion 2 to adjust over the user's chest that extends between an upper point A1 of anchorage to the vehicle and an HC buckle. which can be coupled to an EC closure element fixed to a first lower anchor point A2 of attachment to the vehicle located below and to the side of the upper anchor point and an abdominal portion 3 to adjust over the user's waist that extends between said closing buckle and a second lower anchor point A3 to the vehicle located essentially arranged below the vertical of the upper anchor point A1.

The safety belt 1 according to the invention has two separate sections 20 and 21 in the shoulder portion 2 that are adapted to be joined or separated by means of a closing device 4 that can be opened freeing the user from the belt fastener, such so that a second seat belt opening point is more accessible than the traditional closing buckle.

Alternatively, the abdominal portion 3 of the safety belt 1 may be provided with two

separate sections 30, 31 that are adapted to be joined or separated by the closing device

Four.

As can be seen in greater detail in Figure 2, respective spaced portions 20 and 21 of the shoulder portion 2 have free ends 200 and 210 in the form of a clip. Alternatively, the separate sections 30, 31 of the abdominal portion of the seat belt are provided with free ends 300, 310 also in the form of a clip.

Referring still to Figure 2, it can be seen that the closure device 4 is provided as a carabiner-type closure with a general U arrangement with branches 40 and 41 that are inserted in the clips 200, 210 or alternatively in the clips 30, 310 and a locking lever 42 articulated on one of its branches 40 and which can be fixed releasably on its other branch 41.

As can be seen in greater detail in Figure 3, the closure device 4, alternatively, is provided as a clip type closure with general U-arrangement with a first and second branches 40 and 41 for engagement in the clips 200 and 210 or in the clips 300, 310 of the respective shoulder or 2 shoulder portions 3 of the safety belt and a closure element 43 with a lever arm 430 having a first end 4300 con fi gured in the form of a ring for coupling of a closure bolt 410 with a ball-shaped termination extending from the second branch 41 and a bushing 432 articulated in the first of said branches 40 by means of a pin 44 and lugs 45. Furthermore, it can be seen that the lever arm 430 is mounted inside the articulated bushing 432 supported by its second end 4301 on a replacement spring 46, so that said lever arm can move from a closed position with its first end 4300 in the form of a Nillo coupled to the closing pin 410 of the second branch 41 with the extended replacement spring.

For opening of the closing element 43, the lever arm 430 is pressed by compressing the replacement spring 46 in such a way that the first ring-shaped end 4300 will coincide with the closing pin 410 allowing it to swing around the first of said branches. 40

As will be readily understood by persons versed in the art, the foregoing is merely illustrative of a preferred embodiment of the invention so that technical modifications of all kinds are possible.

Sufficiently, the object of the invention has been described, it only remains to be noted that the embodiments derived from changes in shape, dimensions and the like, as well as those resulting from an application of the foregoing, should be considered included in its scope, so that the The invention will only be limited by the scope of the following claims.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement Document D01, which is considered the closest to the state of the art, discloses (the references in brackets are from this document) a seat belt for vehicles, of the three-point type, with a shoulder strap portion (6) to adjust on the user's chest, which extends between an upper point (2) of anchorage to the vehicle and a closure buckle (4) that can be coupled to a closure element fixed to a first lower point (5) of anchorage to the vehicle located below and to one side of the upper anchor point, and an abdominal portion (7) to adjust over the user's waist, which extends between said closure buckle and a second lower point (3) of anchorage to the vehicle, located essentially arranged below the vertical of the upper anchor point, it being provided that said belt, in its abdominal portion (7), has two separate sections (7a, 7b) that are adapted to be joined or separated by means of a device d e closure (15) that can be opened by freeing the user from the belt support. In addition, the separate sections (7a, 7b) of the abdominal portion (7) of the belt have respective free ends (10a, 10b; 13a, 13b, 13c) in the form of a clip. On the other hand, document D02 discloses (the references in parentheses are of this document) a seat belt (1) for vehicles divided into two parts (3, 3) at a specific point thereof, keeping the ends of said two parts by means of a connection element having a general U-shape with two branches (4, 4) for coupling in the clips (2, 2). In D02 no type of blocking element is described, as an articulated lever, located on one of its branches and that can be released in a releasable manner on the other branch, but by the teachings of document D01, and other State documents of the Technique on seat belts for vehicles, any person skilled in the art could think, without the need to make an inventive leap, of an opening and closing element that joins the two branches of the U that forms the closing device. As explained above, the technical object of the present invention, insofar as it can be interpreted, is not new, since the above documents, among others, are particularly relevant for said object, and therefore also lack inventive activity, all according to the requirements of Articles 6.1 and 8.1 of Patent Law 11/86.
