Definitions

  • This invention relates to a seat belt buckle with three branches, for example for a safety seat for children carried in cars.
  • One known buckle is fixed to one end of one branch of a seat belt which is made to pass between the legs of a child who is carried in a car and seated in a safety seat.
  • the other two branches of the seat belt are disposed in the form of braces on the body of the seated child and each of them carries, fixed to its free end, a rigid tongue, made for example of metal, which is selectively inserted into and fixed in the buckle to form a substantially Y-shaped set of straps capable of securing the body of the child carried in the car with respect to the seat.
  • the branches of the belt are made to open by unlocking the tongues from the buckle by means of a push button provided in the buckle.
  • the principal object of the present invention is to provide a seat belt buckle with three branches, for example for a safety seat for children carried in cars, which can be used to secure a child carried in a car with respect to the seat in a rapid and certain way, while also making the safe condition visible when it is present.
  • a further object is to provide a seat belt buckle as indicated which has a simplified structure, operates in a certain and reliable way and is relatively inexpensive.
  • the present invention provides a seat belt buckle with three branches, for example for a safety seat for children carried in cars, whose essential characteristic forms the subject of the principal claim which shall be understood to be provided as an integral part of this document.
  • the number 10 indicates as a whole the seat belt buckle with three branches, for example for a safety seat for children carried in cars, according to an example of an embodiment of the present invention.
  • the said buckle 10 is used to connect together three branches, R1, R2, R3 of a seat belt of a safety seat (not illustrated) for a child carried in a car, to form a substantially Y-shaped harness to hold the child in the seat.
  • the said buckle 10 comprises a shell 11 of plastic material, for example heat-resistant ABS, formed by the permanent joining of two half-shells 11.1, 11.2, which together form a void 11.3.
  • a shell 11 of plastic material for example heat-resistant ABS
  • the said shell 11 is fixed by means of a slot 11.4 to one end of the branch R1 of the seat belt (Fig. 1).
  • Each of the other two branches R2, R3 of the belt carries at its free end a fixed rigid metal fixing tongue 12.
  • Each of the said tongues 12 has a straight portion 12.1 with a locking notch 12.2 and a loop 12.3 for connection to the corresponding branch R2, R3 of the belt.
  • the said loop 12.3 has a plastic coating (Fig. 6), of heat-resistant ABS for example, which provides, next to part of the corresponding portion 12.1, a guide projection 12.4 (see also Fig. 10), complementary to the guide projection 12.4 provided on the loop of the other tongue 12.
  • the two tongues 12 may be correctly placed adjacent to each other before insertion into the buckle 10, with the corresponding portions 12.1 brought together and parallel with each other and the locking notches 12.2 opposite each other, to facilitate the correct and secure operation of insertion into and locking in the buckle 10, as will be made clearer in the following text.
  • a spring locking mechanism indicated as a whole by the number 13 (Fig. 2) and comprising:
  • the bolt 17 Conversely, by manually pressing the button 18, the bolt 17 is returned, by reverse oscillation of the catch lever 17.4 about its fulcrum, to a retracted position, in opposition to the action of the spring 17.3, thus releasing the carriage 15.
  • the carriage under the elastic force of the return spring 15.2, is automatically returned to its rest position.
  • the bolt 17 also releases the tongues 12.
  • the button 18 is depressed in the aperture 18.1 which indicates to the user the condition of release of the buckle 10, in which the tongues 12, being no longer secured, may be withdrawn from the buckle 10.
  • the opposing means may have a technical configuration different from that described above.
  • FIGs 11 to 13 show a variant embodiment of the buckle according to the present invention, indicated here by the number 20. (In the said figures, similar parts are identified with the same reference numbers as those used in Figures 1 to 10).
  • the opposing means consist of a rocker 22 with equal arms, fitted on the carriage 15 by means of an intermediate pin 23 with its axis orthogonal to the carriage and disposed in its said plane of symmetry.
  • each arm of the rocker 22 is opposite a corresponding slot 14.3 so that the end can be engaged by a portion of the tongue 12.1 when this is inserted into the buckle 10 through the said slot.
  • Fig. 13 clearly illustrates the inoperative condition of the buckle 20 in the case of insertion of only one securing tongue 12.
  • the operative condition of the buckle 20, with portions 12.1 of the buckles 12 correctly inserted fully as a pair, is similar to that of the buckle 10 illustrated in Fig. 7.
  • the opposing rocker 22 directly transmits the simultaneous and balanced thrust exerted by the tongues 12 to the carriage 15, which is thus made to complete its operating movement in opposition to the action of the spring 15.2.
  • the operation of the buckle 20 corresponds exactly to that of the buckle 10, and therefore reference should be made to the explanation of the operation of the buckle 10.
