Abstract
A buckle for a safety belt comprises a pair of opposed holes (5) receiving two balls (6) for locking engagement in two notches (11c) in the shank of a flat tongue (11). A spring biassed ejection member (13) is depressed by tongue (11). A rectangular sleeve (22a) is spring biassed to obstruct the holes (5) to prevent disengagement of the tongue. In order to disengage the tongue, an outer tubular housing (22) is manually displaced axially relative to the tubular support (10) to move tubular member (22a) from obstructing holes (5) whereby spring (14) moves ejection member (13) upwardly to eject the tongue with the balls (6) displaced outwardly. The member (13) is then in a position in which it obstructs holes (5) to return the balls (6) therein. Such a buckle provides a safe and reliable operation with a relatively simple construction. <IMAGE>
Description
SPECIFICATION
Improvements Relating to Safety Belts
The present invention relates to a buckle for safety belts, particularly for motor vehicles, of the type comprising a tubular support of rectangular section which is adapted to receive slidingly a flat tongue carried at the end of the belt and provided with locking notches, locking means carried by the said tubular support and adapted to engage the notches in the tail of the tongue when the said tail is inserted into the tubular support, buckle opening means adapted to be operated manually in order to disengage the said locking means from the notches in the tongue, and a resilient antagonistic member for expelling the said tongue from the said tubular support when the opening means are operated.
The essential aim of the invention is that of providing a buckle of the type specified which is of particularly simplified construction, safe and reliable in operation, and free from obstructions.
One particularly advantageous embodiment of the invention is in addition directed towards avoiding faulty fastening, by ensuring a firm connection between the buckle and the tongue of the safety belt even if the operation of inserting the tongue is effected in an uncertain manner.
Another important aim of the invention is that of providing a buckle equipped with positively acting tongue locking means; by "positively acting" is meant the action applied by direct contact between the locking members and the means for operating them, without the interposition of resilient means which limit the tensile strength of the coupling between the tongue and the buckle.
Yet another important aim of the invention is that of providing a buckle having a strong construction and connected directly to the body of the motor vehicle, together with tongue locking means by the said construction, which means, when in the operative position retaining the tongue, stabilise a direct, mechanically continuous connection between the said tongue and the said strong construction, which takes the tractive forces acting on the belt.
In a simplified embodiment of the present invention the buckle is characterised in that the tubular support has on its smaller faces two oppositely disposed holes in which are received two balls intended for partial engagement in the locking notches provided in the tongue for the purpose of locking the latter; these locking notches have a cam-like profile, in that the resilient antagonistic member is urged by the action of resilient means into a position in which it obstructs these holes, and in that a rectangular sleeve is mounted for sliding on the tubular support and is urged by resilient means into an axial position, in relation to the tubular support, in which it obstructs the aforesaid two holes and prevents the disengagement of the tongue, the internal surface of the said sleeve having a camshaped internal profile which acts with a tripping action on the balls so as to push them towards the interior of the support and to engage the locking notches of the tongue when the latter is inserted into the support, displacing the antagonistic member against the action of the respective resilient means.
In a modified embodiment of the invention, whose aim is to avoid all possibility of incorrect fastening, resulting from an uncertain operation of insertion of the tongue, the antagonistic member is in turn subjected to the retaining action of locking members which retain it in the position corresponding to complete engagement on the tongue and, only this position of the said antagonistic member, permit the tripping displacement of the sleeve which brings about the displacement of the locking members in the locking notches of the tongue.
In this modified embodiment of the invention the outer sleeve is provided with two pairs of notches corresponding to the locking members of the tongue and of the antagonistic member respectively, and its operation in the opening direction, freeing both these locking members, enables the antagonistic member to act as expulsion means for the tongue. Both the antagonistic member and the sleeve are reciprocally connected by resiliently yieldable connecting rods which selectively push and retain in the lowered position the antagonistic member when the sleeve is in the raised position, that is to say the closed position, and vice versa, and retain the antagonistic member in the raised position when the sleeve is in the lowered or open position.The dead centre of the connection formed by the connecting rods is selected to correspond substantially to the halfway position of the said sleeve and antagonistic member, so that the closing displacement of the sleeve is effected with a tripping action, because of the elasticity of the connecting rods, when the antagonistic member is pushed into the lowered position of complete engagement of the tongue.
Further characteristics of the present invention will be seen from the foliowing description given with reference to the accompanying drawings, which are supplied solely by way of example without limitation, and in which:

In the drawings, 1 indicates generally a buckle for safety belts which comprises a tubular support 10 of rectangular section provided at one end with a hole 3 for fastening with the aid of a connecting arm (not shown) of known type to the supporting structure of a motor vehicle. 11 indicates a tongue having a head 1 a provided with a rectangular eye suitable for permitting the fastening of a safety belt (not shown), and a shank 1 b intended to be inserted into the interior of the tubular support 10.The smaller faces of the tubular support 10 have two oppositely situated holes 5 receiving two balls 6 intended for tripping engagement in two corresponding locking notches 11 c provided in the shank 1 b of the tongue 11 in order to permit the locking of the said tongue inside the tubular support 1 0. Inside the tubular support 10 is mounted for sliding an antagonistic member 13 having an end surface 1 3a on which is engaged the free end of the shank 11 b when the tongue 11 is inserted into the interior of the tubular support 1 0.On the smaller faces of the tubular support 10 are formed two tongues 1 Oa folded over towards the interior of the support 10 so as to form a support for a spring 14 inserted inside the tubular support 10 and acting on the end surface of the antagonistic member 1 3 lying opposite the surface 13a.
The spring 14 tends to hold the antagonistic member 13 in such a position in relation to the tubular support 10 that its smaller side faces obstruct the two holes 5 in the tubular support
10. Fastened to the antagonistic member 1 3 is a transverse pin 9 whose ends are slidable in two guide grooves 9a formed longitudinally in the larger faces of the tubular support 1 0.
On the outside of the tubular support 10 is mounted for sliding a sleeve 22 of rectangular section, in the interior of which is fixed a tubular
member 22a, likewise of rectangular section, which has an end surface 22b in the form of a rectangular frame; the smaller sides of this frame are inclined towards the interior df the tubular member 22a, as shown in Figure 1. On the end surface of the tubular member 22a, which is opposite the surface 22b, acts the end of a spring 21 housed in the gap between the the tubular support 10 and the sleeve 22, the opposite end of the said spring being supported on two turned-back tongues 1 Ob formed in the smaller faces of the tubular support 10. The spring 21 tends to hold the tubular member 22 in a position such that its inner surface obstructs the two holes 5 of the tubular support 10.On its larger faces, adjacent its end which is turned towards the end of the tubular support 10, the sleeve 22 has two transverse fins 22c adapted to form a support for facilitating the manual operation of unlocking the safety belt according to the invention.
When the safety belt is in the locked position shown in Figure 1, the spring 14 is compressed and tends to push the antagonistic member 13 in the upward direction and consequently to push the shank 1 b of the tongue 11 in the same direction. Since however the tubular member 22a obstructs the holes 5 in the tubular support 10, the balls 6, being pressed against the locking notches 1 c of the tongue shank 11, prevent the displacement of the tongue and of the antagonistic member 13.
In order to unlock the safety belt it is necessary to apply pressure manually to the fins 22c of the sleeve 22 so as to bring about an axial displacement of the said sleeve in relation to the tubular support 10. Since the sleeve 22 is then in a position in which, the reaction of the spring 21 being overcome, the tubular member 22a no longer obstructs the two holes 5 of the tubular support 10, the balls 6 can be displaced radially outwards through the action applied to them by the cam profiles of the notches 1 c as the result of the expansion of the spring 14. The antagonistic member 1 3 can therefore be displaced axially in the direction of the balls 6, assuming the position shown in Figure 3 and bringing about the expulsion of the shank 1 1b of the tongue 11 from the interior of the tubular support 10.The guide grooves 9a cooperating with the pin 9 fastened to the antagonistic member 1 3 have the purpose of preventing accidental expulsion of the antagonistic member 1 3 from the tubular support 1 0.
When the safety belt is in the unlocked position shown in Figure 3, in order to bring about the locking of the tongue 11 inside the tubular support 10 it is simply necessary to insert the shank 1 b into the tubular support 10 and to apply manual pressure to the tongue 11 so as to bring about displacement of the antagonistic member 1 3 and the compression of the spring 14. When the coupling notches 11 c of the shank 1 b reach positions corresponding to the two oppositely situated holes 5 in the tubular support 1 0, the action of the inclined surfaces 22b on the balls 6 as the result of the expansion of the spring 21 effects the tripping engagement of the said balls 6 in the notches 1 c in the position shown in Figure 1.
In the improved embodiment shown in Figures 4 to 6 (in which like or corresponding parts to those previously described are given the same reference numerals), the support 10 likewise contains the slidable antagonistic member 13 urged by a spring 14 in the direction of expulsion of the tongue 11. The support 10 has a first pair of seats 1 5 for receiving locking members 1 6 adapted to cooperate with the corresponding surfaces 1 c of the tongue for the purpose of retaining the latter.The locking members 1 6 are composed of small cylinders disposed with their axes perpendicular to the plane of the support 1 0 and shaped to be displaced transversely in relation to the longitudinal axis of the buckle, so as to pass from a position of engagement of the tongue, in which position the cylinders are displaced towards the central axis of the support 10 (Figure 4), to a position of disengagement in which the cylinders are displaced towards the outside (Figure 6). A second pair of seats 18 is in addition provided on the support 10, in a position below the seats 1 5 previously described.In the seats 1 8 are accommodated corresponding locking members 19, which are likewise adapted to be displaced transversely for the purpose of engaging and disengaging corresponding locking notches 20 provided on the antagonistic member 13. The locking members 19 are preferably in the form of balls. The locking notches 20 are provided at the end 1 3a of the antagonistic member 13 which is intended to come into contact with the tongue 1 and the seats 1 8 are disposed in such a manner that the balls 19 engage the said notches when the antagonistic member is situated in the completely lowered position against the action of the spring 14corresponding to complete engagement of the tongue 11. The sleeve 22 is mounted for axial sliding on the support 10 against the action of springs 21.In the sleeve are provided a first pair of recesses 23 shaped substantially as inclined planes and intended to cooperate with the cylinders 16, as previously described, and a second pair of recesses 24 intended to cooperate similarly and coorespondingly with the balls 1 9.
Between the first and second pairs of recesses is provided a rectilinear portion 25 spaced apart from the support 10 with minimum clearance. A similar rectilinear portion 26 is also provided as continuation of the recesses 24, so that the latter are positioned between the rectilinear portions 25 and 26. The reciprocal arrangement of the recesses and of the aforesaid rectilinear portions is such that when the sleeve 22 is in the closed position shown in Figure 4, corresponding to the extended position of the springs 21, the rectilinear portions 25 and 26 are in alignment with the cylinders 1 6 and with the balls 19 respectively, so that the said cylinders and balls are prevented from being displaced transversely into the position of disengagement of the tongue and of the antagonistic member respectively.
Conversely, when the sleeve is displaced into the opening position corresponding to the compressed position of the springs 21 , the recesses 23 and 24 respectively are situated in alignment with the cylinders 1 6 and balls 19, so that they are able to make the transverse disengaging displacement towards the outside support 10. This disengagement is effected with a tripping action through the effect of the spring 14.
The latter, acting on the antagonistic member 13, applies to the latter an axial force to which corresponds (as the result of the profile of the locking surfaces 1 7 of the tongue 11 and of the notches 20 of the member 13) a transverse force tending to bring about the aforesaid transverse displacement of the locking members. On the other hand, as soon as this displacement takes place the antagonistic member 13, being freed, acts axially on the tongue 11, which has likewise been freed, so as to bring about the expulsion. As clearly shown in Figure 6, the axial displacement of the antagonistic member resulting from the expulsion brings the rectilinear portion of the said member into contact with the balls, which, being held in the extracted position, are firmly held in engagement with the the recesses 24 of the sleeve so as to retain the latter correspondingly in a secure open position.It will readily be understood that when the tongue is then completely inserted, pushing the antagonistic member as far as it will go, will bring the notches 20 into a position corresponding to the balls 1 9 which, because in turn of the action of the springs 21, will be pushed transversely into engagement with the said notches so as to lock the antagonistic member and at the same time to free the sleeve 22. The latter, under the thrust of the springs 21, will slide axially on the support 10 and assume the position shown in Figure 4, i.e. the closed position. When this displacement takes place the inclined planes of the recesses 23 will displace the cylinders 1 6 into the seats 1 5 of the support in order to bring about the engagement of the said cylinders with the locking surfaces 11 c of the tongue.
In the modified embodiment shown in Figures
7 and 8 it can be seen that the antagonistic
member 1 3 and the sleeve 22 are connected together by resiliently yieldable connecting rods
30. Each connecting rod is for example composed
of two casings 31-32 telescopically connected
together, with a compression spring interposed
between them, so that the connecting rod in
question is resiliently yieldable in the axial
direction. Each casing has an end seat 34, 35
adapted to engage with a hinge action a
corresponding articulation head 36, 37
respectively, disposed on the antagonistic
member 13 and on the sleeve 22; the seats and
articulation heads are preferably spherical in
shape. The spring 14 also acts on the antagonistic
member, as previously described.
From Figures 7 and 8 it can also be seen that the dead centre of the connection formed by the connecting rods 30 is selected so as to be substantially in a position corresponding to the halfway point of the said antagonistic member and sleeve, so that, because of the compressibility of the said connecting rods, the antagonistic member and the sleeve selectively assume and retain, in the case of the former, the raised expulsion position (Figure 7) when the latter is pushed into the open position (downwards in the drawing), and in the case of the latter the raised closed position (Figure 8) when the former is pushed into the position corresponding to complete engagement of the tongue.
It is also obvious that, because of the arrangement of the dead centre of the articulation, in the intermediate position of the movement of the sleeve and antagonistic member the selective passage from one position to the other of the said members will take place with a tripping action; the sleeve is in fact subjected to the resilient action of the connecting rods 30 and the antagonistic member is subjected to the same action and to the extending action of the spring 14 so as to act as expulsion means for the tongue 11.
