Definitions

  • Field of the Invention This invention relates to safety seat belt and harness assemblies of the type used in vehicles for restraining occupants in their seated positions at the moment high rates of deceleration, such as those encountered in a collision, would otherwise throw them forward with respect to the vehicle.
  • Such seat belt and harness assemblies are generally locked into position about the occupant by means of a buckle to which a safety belt is attached, and a tongue, to which another safety belt is attached for joining with the first by insertion of the tongue into a slot in the buckle for locking engagement therewith.
  • the other ends of the belts are most frequently attached to the frame of the vehicle, either directly, or indirectly by attachment to retractors which keep them out of the way when not in use, and provide just the right length of belting when they are.
  • a latch member generally biased to extend through an opening in the tongue, is withdrawn by manually lifting a lever, depressing a button or otherwise depressing the latching mechanism.
  • This invention is directed to a tongue assembly for locking engagement with a seat belt buckle comprising the tongue and a biased tongue-ejecting member attached thereto, which is placed under tension with respect to the buckle by the act of inserting and latching the tongue within the buckle. When the tongue is released it is forceably ejected.
  • the tongue-ejecting member comprises a slideable structure extending from at least one side of the tongue with biasing means arranged for compressive action between the slideable structure and a point on the tongue, and positioned for contact with the buckle while the tongue is inserted therein, whereby when the tongue is inserted in the seat belt buckle, the slideable member is pressed so as to compress the biasing means and exert a force on the tongue in a direction away from the buckle to eject the tongue upon its release from the buckle.
  • FIG. 1 is an exploded isometric view of a preferred embodiment of the seat belt buckle tongue of our invention.
  • FIG. 2 is a cross-sectional view of the tongue of FIG. 1 taken along line 2-2 as assembled, including a representation ofa seat belt buckle as a means of illustrating the condition of the tongue when in locked position within a buckle.
  • This invention relates to a tongue for locking engagement with a safety seat belt buckle, comprising a metal structure shaped at one end for insertion into a seat belt buckle for latching engagement therewith; means for retaining the tongue in locking engagement with a latch of the buckle and an opening in an end of the metal structure, opposite to that shaped for insertion into a seat belt buckle, for the attachment of a seat belt.
  • a biased movable member slideably attached to the tongue for limited travel in a direction parallel to the motion of the tongue on insertion into the buckle, said movable member extending from both sides of the tongue, so that said member contacts the buckle when the tongue is inserted therein, but before it has been inserted a sufficient distance for locking engagement therewith, whereby when the tongue is inserted a sufficient additional distance for locking engagement, it is inserted in opposition to the bias of the movable member, thus leaving the movable member stationary with respect to the buckle throughout the remaining insertion operation, while maintaining a bias against the buckle in a direction to eject the tongue from the buckle when the tongue is released from locking engagement therewith.
  • a safety seat belt buckle so equipped carry an additional safety factor, but it adds a desirable snappy positive action to its operation.
  • the added part is inexpensive, and may be added as an ornament, thus combining attractive appearance with valuable function.
  • numeral 1 is a flat metal structure having an elongated portion 3 for insertion into the slot of a seat belt buckle for engagement with latch member 5 (FIG. 2), thus locking the tongue in the buckle.
  • Opening 8 is provided for the attachment of seat belt 9 (FIG. 2) and grommet ll, fabricated of a suitable polymeric material, such as nylon, serves to protect the webbing from undue wear at this point.
  • Slideable member 7 comprises two slideable portions 12 and 13, and spring 14. Portions 12 and 13 are centrally recessed at and 20, respectively, to produce a cavity when joined together through opening 6 in the tongue, said cavity including the sandwiched opening 6 between them. This cavity serves to contain and completely enclose spiral spring 14.
  • spring 14 is placed in the recess 10 of slideable portion 12, with one end placed against section 16 of the extending part 15, which serves as an end-wall for the spring.
  • Slideable portion 12 which is now holding spring 14 is brought to opening 6 with slideable face 17 toward the tongue, and end-wall 16 toward the tip of the tongue.
  • the end of the spring opposite end-wall 16 is slipped over protuberance 18.
  • This protuberance is centrally located on the edge of opening 6 most distant from the tip of the tongue and is of such size as to fit within the end of the spiral spring and of such length as to extend no more than about one-third of the length of the cavity.
  • the shoulders, where protuberance l8 joins the edge of opening 6, provides the point at which spring 14 acts against the tongue.
  • Slideable portion 12 is now positioned with its slideable face 17 in contact with the surface of the tongue, and with extending part 15, projecting into opening 6, with surfaces 19 being parallel to, and in slideable contact with sidewalls 21 of opening 6, for lengthwise travel within limits permitted by the length of the approximately rectangular opening.
  • the upper surface 22 of the extending part should now be substantially flush with the surface of the tongue opposite to that with which slideable face 17 is in contact.
  • slideable portion 13 is brought with its slideable face toward the surface of the tongue opposite that in contact with slideable portion 12.
  • the male members 23 of one portion are mated with the female members 24 of the other, so that extending part 15 now becomes a con necting bridge between the two portions, thus forming the slideable member 7, positioned for guided slideable lengthwise travel, limited by the longitudinal dimension of opening 6.
  • the shape and arrangement of the male and female members is not critical. Both male members may be placed on either portion, or each portion may contain both male and female members to accommodate those oppositely arranged on the other.
  • the male members may be cylindrical, or they may consist of one or more rectangular extensions with matching recepticals.
  • the two slideable portions enclosing the spring be permanently bonded together, this can easily be done by using an appropriate cement, by heat sealing or by designing the male and female members so they cannot be separated, such as by including tapered heads or other extensions on the male members and splitting their ends a sufficient distance to permit forcing them into the matching openings.
  • the female members would in such a case have corresponding enlargements into which the heads could expand when tension is relieved.
  • Spring 14 may be fabricated of steel, brass, phosphor-bronze, stainless steel or other alloys having the necessary degree of flexibility.
  • the movable member 7 (FIG. 2) comprising the two slideable portions 12 and 13 may be cast from metal, but preferably these two portions are composed of polymeric material such as nylon.
  • grommet H is forced into elongated opening 8 of the tongue.
  • numeral 25 represents any typical safety seat belt buckle.
  • tongue 1 has been inserted into slot 26, and urged forward until the forward surfaces of slideable member 7 come in contact with the seat belt buckle in the area of the slot 26.
  • the tongue has not been introduced far enough for latch 5 to move into opening 4 of the tongue, and, in fact, the tip of the tongue has forced the latch downward against the opposition of spring 27, where it remains, pressed against the tongue.
  • the sliding member 7 is held stationary with respect to the buckle by its contact with the buckle at 26, but the tongue continues to advance toward locking engagement, as it slides past moving member 7. As it does so, it compresses spring 14 between the shoulders of protuberance l8 and the end wall 16, thus storing potential energy in the spring until finally, opening 4 in the advancing tongue reaches latch S. The latch is then urged upwardly by spring 27 into opening 4, thus locking the tongue against withdrawal. Compresses spring 14 pressing against the shoulder of protuberance l8 acts in a direction to eject the tongue, which, however, re mains locked by latch member 5.
  • spring 14 ejects the tongue as a consequence of the force of the spring against the tongue, specifically by pressure against the wall of opening 6 most distant from the tip.
  • the reaction is against the buckle casing by virtue of the fact that the spring acts against wall 16, a part of movable member 7, which is pressed against the buckle housing at point 26.
  • the ejected tongue slides in relation to the movable member 7 until the spring has expanded to substantially fill the cavity within which it is contained.
  • the potential energy stored in spring 14 by the act of inserting the buckle is thereby released as kinetic energy in expelling or ejecting the tongue.
  • the buckle would be held in one hand of the wearer and the tongue in the other, but the tongue is ejected well away from the latching mechanism, thus preventing inadvertent re-latching of the tongue. it also provides a distinctive snappy separation of the tongue from the buckle which is noticeable and impressive to the user.
  • a tongue assembly for locking engagement with a seat belt buckle comprising:
  • a tongue and a biased tongue-ejecting movable member attached thereto which is placed under tension with respect to the buckle by the act of inserting and latching the tongue within the buckle, whereby, when the tongue is released, it is forceably ejected therefrom;
  • the biased tongue ejecting member is slideably attached to the tongue for limited travel thereon in a direction parallel to the motion of the tongue on insertion into the buckle, said movable member extending from at least one side of the tongue so that said member contacts the buckle when the tongue is inserted therein, but before it has been introduced a sufficient distance for looking engagement therewith, whereby when the tongue is inserted a sufficient additional distance for locking engagement, it is inserted in opposition to the bias of the movable member, thus leaving the movable member stationary with respect to the buckle throughout the remaining insertion operation, while maintaining a bias against the buckle in a direction to eject the tongue from the buckle when the tongue is released from locking engagement therewith;

  • tongue assembly has a tip at one end for insertion into the buckle and one portion of the movable member has an extending part projecting from its contacting face and integrated therewith, said part being adjacent to the end nearest the tip of the tongue, said part extending through the opening in the tongue to form a connecting bridge between the two portions comprising the movable member, by means of which they may be attached, said part having parallel sides for slideable lengthwise travel,
  • each portion of the movable member has a centrally located recess which, together with the opening in the tongue with which it cooperates to form a cavity for totally enclosing the biasing means, and wherein said recess in the portion of the movable member containing the projecting part, extends partially through said projecting part thereby forming an end wall to the cavity for containing the biasing means.
  • means for the substantially permanent attachment of the two portions constituting the movable member comprise male structures in one portion and mating female structures in the other portion for engagement therewith.
  • the biasing means comprises a coiled spring having cylindrical outside dimensions such as to fit within the cavity formed by the opening in the tongue and recesses in the movable member so that by forcing the movable member, in a direction away from the tip of the tongue, the spiral spring is compressed between the end wall of the cavity, and the edge of the opening in the tongue most distant from the tip of the tongue.
