ABSTRACT OF THE DISCLOSURE A buckle for a belt, including a first pivotally mounted lever member adopted to engage a tongue of a belt, biasing means for urging the first lever member in the direction of engagement of the tongue, a second pivotally mounted lever member coupled to the first lever member, and a cap member positioned over the first and second lever members and having an opening therein through which the second lever member is accessible so that the second lever member may be selectively pivoted to disengage the first lever member from the tongue.

This invention relates to a buckle for a belt, particularly a safety belt for use in an automotive vehicle or aeroplane.

Safety belt buckles commonly are of what could be referred to as a clam shell construction, commonly called lever type construction in the trade. In other words, they employ two members which pivot on each other in clam shell fashion. When the clam shell is opened, the tongue of the belt which is inserted and held in the clam shell is released from engagement with a catch within the clam shell. Commonly the two members forming the clam shell constitute the outer parts of the buckle. Such buckles suffer the disadvantage that they can be opened accidentally quite easily, since opening is achieved merely by lifting one part of the clam shel relative to the other, and this part of the clam shell can be lifted accidentally by catching on clothing, etc.

It is one object of this invention to provide a buckle which will meet the requirements of all government regulations, standards, etc., applicable to safety belts and in which all of the moving parts are enclosed in a housing in such a manner that forces exerted on the Housing itself cannot open the buckle.

In brief, in accordance with the broad aspect of this invention, there is provided a belt buckle that includes a base member, first and second lever members, a catch member carried by the first lever member, and means pivotably mounting the first lever member on and above the base member about a first pivot axis for movement of the catch member towards and away from the base member. When the catch member is moved towards the base member, it is adapted to engage a catch engageable part of a tongue of a belt when this tongue is inserted between the base member and the first lever member. The catch member disengages from this catch engageable part when the catch member is moved away from the base member. The second lever member is pivotably mounted on the side of the first lever member remote from the base member about a second pivot axis which is parallel to the first pivot axis. Parts of the first and second lever members are coupled together at a point which is spaced from but on the same side of both of the pivot axes of the lever members, so that movement of the end of the second lever member on the other side of the second pivot Re. 27,438 Reissued July 18, 1972 ice axis towards the first lever member lifts the part of the first lever member which carries the catch member. Spring means bias the aforementioned one end of the second lever member away from the base member and bias the aforementioned part of the first lever member towards the base member. A cap member is provided and has an opening therein. Means secure the cap member fixed in position on the base member with the cap member positioned over the first and second lever members, but with the aforementioned one end of the second lever member being accessible through the opening in the cap member.

This invention will become more apparent from the following detailed description, taken in conjunction with the appended drawings, in which:

FIGURE 1 is an exploded perspective view of a buckle embodying this invention with the cap member thereof shown in phantom outline,

FIGURE 2 is a section taken along the longitudinal axis of the buckle shown in FIGURE 1 when in assembled position and with the buckle closed, and 7 FIGURE 3 is a view similar to FIGURE 2 but showing the buckle opened.

Referring now to the drawings, a buckle embodying this invention includes a base member 10 which may be generally U shaped in configuration having spaceds'apart, upstanding,

parallel side walls

11 and 12 and a cross piece 10a extending therebetween, it being understood that

side wallls

11 and 12 and cross piece 10a are integral and may be formed, for example, by stamping a suitable sheet of a metal such as steel.

Towards the front end of base member 10 there are

openings

13, 14, 15 and 16 in

side walls

11 and 12,

openings

13 and 15 being aligned with each other, and

openings

14 and 16 being aligned with each other. Passing through

openings

13 and 15 is a pin 17 which is headed, as at 18, at both ends thereof and thereby is retained on base member 10. Passing through

openings

14 and 16 is a pin 19 headed, as at 20, at both ends thereof, and thereby retained on base member 10.

Pins

17 and 19 may be free to rotate, or they may be fixed to

side walls

11 and 12. It will be noted that pins 17 and 1-9 are spaced-apart and parallel to each other.

A lever member 21 is provided, and may be a metal stamping, for example. Lever member 21 includes a generally fiat portion 22, a generally Z shaped end portion 23, and an upwardly inclined end portion 24. Lever member 21 also has spaced-apart

cars

25 and 26 in which

openings

25a and 26a respectively are provided. Pin 19 extends through these openings in

cars

25 and 26 so as to pivotally mount lever member 21 above cross piece 10a about a pivot axis adjacent oneend of lever member 21. In flat portion 22 of lever member 21 there is formed a catch member 27, this catch member constituting a part of lever member 21 but being cut on three sides therefrom and bent downwardly out of the plane of fiat portion 22, as best shown in FIGURES 2 and 3.

A second lever member 28, which also may be a metal stamping, is provided. Lever member 28 is of generally Z shaped configuration but has a hook shaped end portion 29 which turns under and catches a part of the Z shaped end portion 23 of lever member 21, as best shown in FIG- URES 2 and 3. Lever member 28 also has spaced-apart ears 30 each provided with an opening 30a through which pin 17 extends so as to pivotably mount lever member 28 intermediate its ends on the side of lever member 21 remote from cross piece 10a but about a pivot axis which is parallel to the pivot axis defined by pin 19. It will be noted that lever member 28 has an opening 31 therein, the purpose of which will become more evident hereinafter. Attention is directed to the fact that

lever members

21 and 28 are coupled together (by means of hook haped end portion 29 and Z shaped end portion 23) at tpoint which is spaced from but on the same side, i.e., the efthand side in FIGURES 2 and 3, of both of pins 17 and L9.

Coiled about pin 17 are two coil springs 32 each

havng ends

33 and 34, although only one coil spring may )e employed, if desired. Ends 33 pass through opening l1 and bear against the part of lever member 28 on the efthand side of pin 17, while ends 34 bear against fiat portion 22 of lever member 21. Thus, it may be seen hat springs 32 bias the part of lever member 28 on the "ighthand side of pin 17 away from cross piece ltta vhile they also bias the flat portion -22 of lever memer 21 carrying catch member 27 towards cross piece a.

Securely fastened to base member 10 is a cap mem- I61 35 which may be formed of plastic or steel, for extmple. Cap member 35 has a generally rectangular openng 36 provided in an upwardly inclined front part 37 hereof. Cap member 35 is fixed in position on base memer 10 with the cap member positioned over lever mem- JCI'S 21 and 28 and cross piece 10a and with the side valls 36a of cap member 35 positioned outside of and :nclosing

side walls

11 and 12. As best shown in FIG- JRES 2 and 3, however, the part of lever member 28 )n the righthand side of pin 17 registers with and is .ccessible through opening 36.

Cap member 35 is secured to base member 10 by havng the front wall 38 of cap member 35 provided with L shoulder 39 that engages projections 40 extending forvardly from side walls 11 and 1-2, and also by means if pine trees 41 that extend into openings 42 in proections 43 formed integral with cap 35, the pine trees l1 biting into the side walls defining openings 42 to re- .ist any attempt to lift cap member 35 from base mem- 181' 10.

Base member 10, or more specifically, cross piece 10a hereof, is provided with a hook 44, the purpose of which vill become more apparent hereinafter.

Slidably mounted in inclined slots 45 in side walls 11 lIld. 12 is a knurled pin 46. One part 47 of the webbing )f a seat belt passes through an opening 60' in cross )iece 10a and is looped around pin 46. When this part l7 of the webbing is tightened, pin 46 slides to the posiion shown in FIGURES 2 and 3, thus clamping the vebbing between pin 46 and an upturned flange 46a so LS to prevent sliding of the webbing over pin 46. The ength of the webbing may be adjusted, however, by liding pin 46 towards the front of the buckle, thereby reeing the webbing for movement about pin 46. The means which have just been described and which serve o clamp webbing 47 and permit it to be adjusted in ength are conventional in nature and, per se, form no art of this invention.

The other part 48 of the webbing is shown in FIG- JRE 2 and is fixed to a metal tongue 49 having an openng '50 therein, tongue 49 being provided with a shoulder 1 that is adapted to engage catch member 27.

The normal position of the various components of a )uckle embodying this invention is as shown in FIG- RE 2. In order to fasten the seat belt, it is only necssary to insert tongue 49 between lever member 21 and :ross piece 10a. Upturned end 24 of lever member 21 ogether with front wall 38 of cap member 35 ensures hat tongue 49 will be inserted properly into the buckle. [be leading edge of tongue 49 engages catch member 57 forcing lever member 21 upwardly until tongue 49 s inserted to the position shown in FIGURE 2, at which oint springs 32 cause catch member 27 to drop into upening '50 and engage shoulder 51. The buckle now 5 closed, and the seat belt fastened securely. Because :atch member '27 is below pin 19, any attempt to pull ongue 49 from the buckle results in catch member 27 )eing forced even more strongly against shoulder 51.

It will be noted from FIGURE 2 that tongue 49 exends into hook When it is desired to open the buckle and release the seat belt, pressure is exerted on the part of lever member 28 to the right of pin 17 in the direction shown by the arrow in FIGURE 3. This is done by the operator inserting his finger through opening 36 and depressing lever member 28. Hook shaped end 29 of lever member 28 lifts lever member 21 and catch member 27, the latter being lifted above tongue 49, thereby freeing catch member 27 from engagement with shoulder '51 and permitting withdrawal of tongue 49. If the engagement between catch member 27 and shoulder 51 should result in lifting of tongue 49, this is overcome by hook 44- which restrains the tongue from movement away from cross piece 10a when catch member 27 is lifted.

By arranging the lever members and their pivot pins in the manner shown in the drawings, a mechanical advantage on opening of about 3 to 1 can be obtained. By rearranging the relative position of the pivot pins, the mechanical advantage can be varied at will, e.g., to 2.5 to 1 or 2 to 1.

Since springs 3-2 bear against both

lever members

21 and 28, rattling of these lever members is minimized. It will be appreciated, however, that springs 32. may be arranged other than about pin 17 as long as the springs bias catch member 27 towards cross piece 10a and the end of lever member 28 to the right of pivot pin 17 away from cross piece 10a.

It will be noted that cap member 35 is fixed in position and does not move when the buckle is opened or closed. Therefore, if cap member 35 becomes caught in clothing or forces are exerted thereon accidentally, this cannot cause the buckle to open.

It also will be noted that there is no fulcrum in cap member 35, as has been the case in prior art clam shell type buckles, so that the bearing pressure of a pivot pin on plastic or metal cap 35 is avoided.

It will be appreciated that base member 10 may be of a diiferent configuration than that shown. Indeed, it may just be a plate with projecting tabs on which

lever members

21 and 28 are pivotably mounted.
