Definitions

  • ABSTRACT A seat belt buckle which can be readily assembled by serially arranging its component parts in an open-faced buckle housing, then pressing a cover plate into locking engagement with the buckle housing to complete the assembly.
  • An apertured tongue inserted into a slot in the buckle housing depresses a biased latching member having a wedge shaped latch until said latch coincides with the aperture and is urged into it by the biasing means, thus locking the tongue in place.
  • Release of the tongue is achieved by means of a manually actuated United States Patent [191 Lohr SAFETY BELT BUCKLE Thomas E. Lohr, Warren, Mich.
  • This invention relates to seat belt and harness assemblies of the type utilized in automobiles for retaining an occupant in a seated position within the automobile.
  • Such seat belt assemblies usually include at least two straps or belts anchored to the vehicle body with one of the straps being connected to a tongue and the other to a buckle, whereby two of the straps may be disposed over an occupants lap and the tongue inserted into the buckle so as to be retained therein until manually released by manipulation of the buckle mechanism.
  • buckle assemblies are found in the prior art and practically all incorporate some type of latching means which co-acts with a tongue and is movable between latched and release positions whereby the tongue is retained within the buckle in the latched position and may be removed from the buckle in the release position.
  • the buckles employ various sub-assemblies, device's, linkages, etc. for attachment or co-action with latching means.
  • the assemblies normally include a support structure such as a housing. Quite frequently the housing takes the form of a flat metal plate wrapped into a channel-like member having a substantially rectangular or similarly enclosed cross section. Examples of such prior art assemblies are shown in vU.S. Pat. No. 2,995,792 and 3,203,065.
  • the tongue of the buckle disclosed is released by pressure on a push button in the top center of the buckle.
  • Releasing a safety buckle by the operation of a push button such as that of the last cited patent generally requires the use of two hands, one to hold the buckle while the button is pushed. This can become a time consuming operation, and might be a problem for arthritics or others who lack the full facility of both hands.
  • the push button of US. Pat. No. 3,522,640 occupies a small fraction of the total area of the face of the buckle; hence, in an emergency, the user might have difficulty in quickly locating the actuating area.
  • the push button in hinged, so that should the user press at a point near the hinge, he would actuate the release mechanism at a considerable mechanical disadvantage.
  • the buckle of the present invention is designed for easy assembly by arranging its component parts in an open-faced buckle housing, then pressing a cover plate into substantially permanent locking engagement with the buckle housing to complete the assembly of the buckle as a functional unit.
  • the design of the buckle permits ready release of the tongue by either one or two handed operation.
  • FIG. 1 is an exploded perspective view of one embodiment of the present invention.
  • FIG. 2 is a perspective view illustrating the manner in which two elements of one embodiment are themselves, assembled into the last component to be fitted into the housing at the time of assembly.
  • FIG. 3 is a plan view of a complete assembly, representing one embodiment.
  • FIG. 4 is an enlarged cross-sectional view taken substantially along line 4-4 of FIG. 3.
  • FIG. 5 is an enlarged longitudinal half section through line 5-5, FIG. 3, illustrating the locked position of the buckle.
  • FIG. 6 is the same as FIG. 5 with the exception that it illustrates the release position of the buckle.
  • FIG. 7 is an enlarged longitudinal section through line 7-7, FIG. 3, differing only in that the buckle is shown in the release, rather than in the locked position.
  • FIG. 8 is a plan view of the partially assembled buckle, all components being present with the exception of that of FIG. 2, which serves as a cover for the opening of the housing when the buckle is completely assembled.
  • FIG. 9 is a plan view of the assembled component of FIG. 2, which when pressed into place as the. cover of the partially assembled buckle of FIG. 8, completes the assembly.
  • FIG. 10 is a partial section through line 10-10 of FIG. 9.
  • FIG. 11 is a partial section through line 11-11 of FIG. 8.
  • FIG. 12 combines the partial sections of FIG. 10 and 11 to illustrate how they cooperatively and permanently lock together when the component of FIG. 9 is pressed into place as the cover of the partial assembly of FIG. 8 to provide the final complete assembly.
  • FIG. 13 is an enlarged perspective view of the preferred type of fastening hooks accompanied by four partial perspective views of other possible variations. These hooks are common to all embodiments of the present invention.
  • FIG. 14 is a perspective view of the tongue, illustrating the opening into which the latching member is urged, when the buckle is in locked position. The twodimensional taper of the leading edge is also shown.
  • FIG. 15 is a perspective view of the complete assembly in lock position with the tongue secured in place, and the seat belting attached.
  • FIG. 16 is an exploded perspective view of a second embodiment wherein release of the tongue is achieved by actuating a push button rather than by raising a lever.
  • the tongue illustrated as FIG. 14 is equally applicable to this embodiment, and the operation of the moving parts, the latching member (latch bar), biasing means, and apertured cover plate are sufficiently similar so that their cooperative action can be readily visualized by reference to FIGS. 4-8, 10-13 and 15.
  • the buckle assembly comprises a housing 22, a slideably arranged latch bar 24, biasing member 26 for urging the latching bar into latching engagement with a tongue 58, guide members 28 for guiding the latching bar, a lift lever 30 manually operable and pivotally arranged with one arm constituting a lifting member outside the buckle housing and the other comprising two cams 50 and the fulcrum or pivot points 52, within the buckle housing; a housing cover-plate 32 having means 34 for essentially permanent attachment to the housing, lugs 36 extending into the cavity of the housing to which the lift lever is pivotally attached by pivoting pins 38, thereby locating the fulcrum of the lift lever, and an aperture 40 through which one arm of the lever extends downwardly into the housing.
  • Housing 22 further includes a flange 42 and an opening 44 therein, for attaching a seat belt thereto.
  • the housing 22 is recessed on one face 46 (the front) to accommodate the cover-plate 32 so that it may lie flush with the front surface of the buckle, when assembled.
  • the housing includes surfaces 60 in the cavity 48 which extend from the wall toward cavity section 57 for receiving the latch bar 24, and for limiting movement of the latch bar to movements substantially parallel to the surfaces 60.
  • Extended surfaces 60 also serve to shape the cavity into essentially three interconnected cavity sections, two small sections 54, one near each wall of the buckle to accommodate lugs 36 of the cover-plate and earns 50 of the lifting-lever. They are sufficiently commodious to permit free motion of the cams as well as of cam followers 56 of the latch bar 24.
  • latch bar 24 which includes latch bar guides 28 and ramp latch member 64. Connecting these three cavity sections are the parallel sided openings 60.
  • an opening 62 which extends through a thickness of material comprising the wall of the buckle at this point. It presents at the surface a large, substantially rectangular, opening taking up most of the end of the buckle housing, but it funnels down to a long narrow rectangular opening 66, sized to accommodate tongue 58. This rectangular opening continues through an appreciable thickness of material to thus communicate with cavity section 57 within. Rectangular opening 66 has parallel walls and thus serves to guide tongue 58 into the cavity, limiting the motion to an inward thrust or to its removal without appreciable side play.
  • the leading edge of tongue 58 has a two-dimensional taper 90 (FIG. 14) for easy entrance into the opening, and the funnel-like entrance further facilitates the rapid introduction of the tongue without need of searching or probing for the slot.
  • FIGS. 1, 2, l0, l1, l2 and 13 there are, as shown, a plurality of fastening hooks or catches which extend from the under surface of the cover-plate and preferably constitute an integral part of said coverplate.
  • Each of these fastening hooks comprise a somewhat flexible shank perpendicular to said cover-plate,
  • FIG. 13 presents an enlarged perspective drawing of the preferred design of an individual hook, with shank 94 and head or barb 96.
  • Sufficient flexibility is required of the shank, as illustrated by the dotted lines, so that when force, having a horizontal vector in a direction opposite to that in which the barb extends, is applied to said barb, the shank will bend sufficiently to bring the tip of the barb directly over the base of the shank, and when said force is removed, the barb will spring back to substantially its original position.
  • hooks are preferably positioned on the under surface of the cover-plate, so that the substantially right angled barb of each of the hooks is directed approximately toward another hook, either adjacent or diametrically opposite.
  • they should be paired, that is the barbs of a pair, whether adjacent or diametrically opposite should be directed approximately toward each other.
  • the barbs of the pairs may be directed away from each other, in fact the direction of the barbs is not critical as long as they do not all face in the same direction, linearly or circularly.
  • shafts or bores 70 equal in number to the fastening hooks, perpendicular to the face of the buckle, which begin in the recessed surface 46 of the buckle housing, and extend perpendicularly through to an inner surface, said surface preferably defining a section of the irregularly shaped cavity 48 of the housing 22.
  • These bores are positioned to essentially correspond with the position of hooks 34 of cover plate 32, when said plate is positioned above recess 46 of housing 22, except that in the case of each hook and its corresponding bore, the side of the bore adjacent to the barb of the hook is aligned in touching relationship with the shank of the hook.
  • the bore is of sufficient diameter to accommodate the barb of the hook, but as positioned, the barb extends beyond the edge of the bore.
  • the barb is so shaped, however, that when the hook is pressed downwardly toward the bore, the wedge shaped forward end of the barb causes the shank to bend under stress, sufficiently to admit the barb into the bore.
  • the depth of the holes, between the surface of the recess area 46, and the surface of the cavity with which they communicate, is shorter than the shank of the I hooks by an almost imperceptible amount (no more than a few thousands of an inch).
  • the attachment means or hooks 34 have limited flexibility, with the hook ends being tapered or shaped to permit entry into the holes, so that the cover-plate may be pressed into the recess. The hooks are thereby caused to bend or give sufficiently to enter the holes. The hooks are then under considerable side stressbut as the barb of each hook reaches the surface of the cavity to which the opening communicates, it snaps over the edge of the surface of the cavity, thus relieving most of the stress and permanently locking the cover-plate in place, see FIGS. 8, 1 0 and 12.
  • the depth of the bores may exceed the length of the hooks, and their walls may be threaded or ribbed. With this alternative, the bore need not enter a cavity. When the hooks are forced into the bores, and
  • the cover-plate is pressed into the recess, the barbs snap from thread to thread or rib to rib until they snap into the last one that each of the hooks full length will permit.
  • Other means for attaching the cover, rather than hooks may be substituted, particularly when the holes are threaded or ribbed.
  • projections, threaded or ribbed to fit the corresponding bores, but longitudinally split one way or two, and rounded or pointed so they may be pressed in and permitted to expand to fill the threads or ribs, may be employed.
  • the hooks are preferred since they cannot pull free and are self-tightening.
  • the undersurface 76 of barb 96 of hook 34 is not parallel to coverplate 32. Rather, the undersurface 76 of the barb slants slightly away from the surface of the cover-plate as it leaves shank 94. In other words, the vertical distance between the barb 96 and cover-plate 32 is somewhat less, when measured perpendicularly from the point where the barb joins the shank to the undersurface of the cover-plate 32 (distance A), than when measured from the tip of the barb to the undersurface'of said cover-plate (distance B).
  • This construction of the barb is preferred, for when the length of the corresponding bore between the surface with which it communicates is more than the distance A, but less than distance B, and is preferred, then when each hook is pressed into its corresponding bore, and the barb snaps over the inner surface, it will pull the cover-plate tight into its recess in the housing. The barb will be stopped in its lateral motion across the inner surface when it reaches the point where the distance between the undersurface 76 of the barb and the surface of the cover-plate precisely equals the length of the bore between the surfaces with which it communicates. Further, the shank will still have residual stress, so that should there be a tendency for any space to develop between the coverplate and the recessed surface against which it lies, due
  • the assembly of the buckle is easily achieved (FIGS. 1 and 16), since the components are essentially added to the housing serially, and locked into place.
  • the biasing means shown as a spiral spring 26 is placed in cavity 48 of housing 22.
  • the bottom wall of the buckle is recessed or otherwise designed to prevent horizontal slippage of the biasing means.
  • the two guide members 28 are placed, one each in the two cavities 54, with their backs 72 adjacent and parallel to the outer wall of each cavity 54.
  • the parallel open channels of the guide members 28 face each other, and their outer surfaces fit snugly within parallel sided surfaces 60 of cavity 418.
  • the latching member 24 is placed in the cavity, essentially centered over the biasing means 26, with cam followers 56 facing upward, slideably positioned within guides 28, with each cam follower extending into its corresponding cavity 54. Pressure on the latching member 24 will now cause it to freely move downward in a direction parallel to surfaces 60 against the action of the biasing means, while remaining parallel to the back of the buckle at all times.
  • cover-plate/lift-lever assembly of FIG. 2 is placed over the cavity of the buckle housing which now contains the biasing means, the latching member and the two latching member guides.
  • the cams 50 of the lift-lever 30 in pivotal cooperation with lugs 36 of cover plate 32 are dropped into their respective cavities 54 in the buckle housing.
  • the attachment means, shown here as hooks, four in number, attached to the under surface of the cover plate, are then placed into their respective bores 70 and the cover-plate/lift-lever assembly is pressed firmly against the housing containing the remaining parts as in FIG. 8 until all the hooks snap into place and the cover plate is flush with the buckles surface, thus easily and permanently locking the entire assembly tightly together without the use of nuts, bolts, rivets or the like.
  • FIG. 16 is an exploded view of a second preferred embodiment wherein the mechanism is actuated by a push button rather than a lever.
  • the buckle assembly comprises housing 22, a slideably arranged latching member 24, biasing member 26 for urging the latching member into latching engagement with tongue 58, and guide members 28 for guiding not only the latching member 24, but in the case of this second preferred embodiment, the manually actuating member as well.
  • the manually actuating member comprises push button 102, positioned on bridge 104 which spans latching member 24 and therefore the channel into which the tongue is inserted.
  • legs 106 slip down over the upward extending legs 108 of latching member 24, and surfaces 110 bear on the surfaces 112 of the legs of the latching member, so that pressure applied manually to push button 102 will be transmitted through surfaces 110 to the latching member 24, thus opposing the upward pressure of biasing means 26.
  • Guides 28 fit snugly into the pockets formed by surfaces 60 and 75 in the housing, and provide channels for the linear movement of legs 108 of the latching member and legs 106 of the manually operable member or push button assembly 100. It can be seen according to the illustration of FIG. 16, that the outer surfaces 114 and the end surfaces 116 of push button assembly 100 will be in slideable contact with the back 72 and inner side surfaces 122 of the guide members and that the side surfaces 120 of the latching member 24 will also be in slideable contact with the inner side surfaces 122 of guides 28.
  • the biasing means presses the latch member upwardly from the wall into the latched position and indirectly, through contact surfaces 112 of the latching member and 110 of the push button assembly, presses push button 102 into aperture 40 of the cover plate.
  • the dimensions of the push button are preferably a little less than those of the aperture 40 of the cover plate but the surface of said push button is kept substantially flush with the surface of the cover plate by flange 124 below the cover plate. The dimensions of this flange slightly exceed those of the aperture. Preferably, this flange is an integral part of the push button.
  • shoulder 104 of the push button assembly or other means may be used to retain the push button within the housing.
  • the legs of the push button assembly may be tapered so that pressure manually applied unevenly to one side of the button can cause the push button to rock toward the point of pressure without binding and without adversely affecting its operation.
  • This feature of the present invention coupled with the large area of the preferred button relative to the area of the top of the buckle permits ready release of the tongue with only one-handed operation.
  • the manually operable member or push button assembly may comprise an assembly of components but preferably it is fabricated in one piece and preferably of polymeric materials, reinforced nylon being especially preferred. This construction contributes to the ease of operation as well as to the lightness of the buckle. A smooth action is obtained, because of the self-lubricating quality common to certain polymeric substances and particularly to nylon.
  • tongue 58 to which one section of seat belt is attached is inserted and thrust all the way into opening 66 of the seat belt buckle, to which the other section of seat belt is attached, until it seats in groove 68.
  • the tapered end of tongue 58 encounters sloping latch member 64, and thereby urges the latch bar downward toward the back of the buckle against the lesser force of the biasing means 26.
  • centrally located aperture or recess 72 is aligned with latch member 64 which is then urged upward by the biasing means, into said opening.
  • the slope of the wedge-shaped latch member Because of the slope of the wedge-shaped latch member, it does not restrict the forward movement of the tongue into the buckle, but since the sloping wedge ends in an abrupt shoulder, perpendicular to the buckle and the inserted tongue, no amount of pull on the tongue can release it, once the latch member has snapped up into place, as shown in FIG. 5.
  • Lift lever 30 permits one hand operation of the buckle and provides a mechanical advantage, so that the buckle may be readily unlatched with a minimum of force, and without resort to a complicated intermediate structure.
  • pressure on any portion of the push button 102 is transmitted to the latching member 24 through surfaces of the former which are in direct contact with surfaces 112 of the latching member. Release of the tongue 58 is obtained exactly as in the case of the first embodiment.
  • the introduction of the tongue 58 and the latching thereof by the latching member is also identical to the action of the first embodiment.
  • the buckle and tongue are preferably made of metal.
  • the housing may be steel or die cast aluminum.
  • the latching member may be of steel or sintered iron.
  • the latching member guides are preferably of stainless steel to insure smooth operation of the latch bar. It will be understood that the guides may be made of various metals, alloys, plastics, or other materials to facilitate the movement of the latching member.
