Definitions

  • This invention relates to the construction of safety belt buckles of the type actuated by a pivoted lever.
  • This type of mechanism is well-established, and the movement of the lever is normally used to disengage the locking mechanism to permit separation of the sections of the movement, in addition to establishing the normal locking buckle.
  • the lever positions a cam which normally maintains the lateral interengagement of abutments and recesses on the opposite sections of the buckle, respectively, for the transmission of forces resulting from belt tension.
  • lever-actuated buckle mechanism While the use of lever-actuated buckle mechanism is well known in this art, it has been the practice to mount the lever for pivot movement in such a direction that a large component of the manual release force tends to pull the buckle section containing the mechanism in the direction of normal belt tension, particularly when the lever is near the full release position. In other words, the buckle sections may be unlocked, but the release force on the lever continues to hold one belt section closely about the wearer. In normal release (as opposed to crash conditions), the relatively light belt tension is thus taken on one side of the belt. There usually is insufficient tension remaining in the opposite side to pull the unlocked buckle sections apart, and the result is to make disengagement of the belt a two-handed procedure.
  • a modified form of the invention provides for the desired alignment of the lever movement by eliminating the coaxial relationship between the cam and the bandle pivot, and providing for a torque transfer from the lever over to the rotatable cam.
  • applicant has found it desirable to separate the portion of the buckle serving as an adjustable belt terminal from that which contains the active locking mechanism of the buckle. By displacing the adjustable terminal to a position further down the belt section, the mass normally associated with that portion of the device is removed from the lap of the wearer. This is.
  • the invention also provides a counter-balancing of the lever which will tend to minimize the tendency for crash inertia to throw the lever to release position.
  • the counterbalance arrangement therefore may permit the use of a very light return spring without sacrifice of safety, and therefore further favor the use of the safety belt by persons who normally just dont care to manipulate this equipment.
  • FIGURE 1 is an exploded view showing the buckle sections disengaged.
  • FIGURE 2 shows a plan view of the buckles in the engaged condition, with the lever swung back beyond the normal release position to expose the interior mechanism.
  • FIGURE 3 is a sectional elevation showing the buckle sections in the fully engaged and locked condition.
  • FIGURE 4 shows the buckle sections released.
  • FIGURE 5 is a sectional elevation showing an intermediate position in the engagement of the buckle sections.
  • FIGURE 6 is a plan view of a separate adjustable belt terminal of a modified form of the invention.
  • FIGURE 7 is a sectional elevation of the terminal on the plane 77 of FIGURE 6.
  • FIGURE 8 is a plan view showing the engaged buckle sections of the modification of the invention associated with the separate belt terminal.
  • FIGURE 9 is a sectional elevation on the of FIGURE 8.
  • FIGURE 10 is a sectional elevation of a modified form of the invention in which the lever is mounted on a shaft plane 9-9 which is not coaxial with the locking cams, with the device in the fully locked condition.
  • FIGURE 11 is a view of the release position of the mechanism shown in FIGURE 10.
  • the bars 33 and 34 together form. an adjustable terminal whereby the length of the belt may be adjusted to suit the needs of the particular oc-- cupant.
  • the belt can be tightened by pulling on the free end 35.
  • the length can be increased by pulling on the: belt 21 while the opposite knurled, ends. of the bar 34- are grasped between. the fingers to. separate the bar 34- from the relatively fixed bar 33.
  • Application. of tension to the belt will then cause the bar 3,4 to move toward.
  • the buckle section 30 includes a central plate portion. 36 which contains the abutments 28 and 29, and is alsoprovidedwith a slot 36a for receiving the belt 37.
  • The: spaced side flanges 38 and 39 include the lanced portions. 40 and 41 providing offsets extending inwardly toward. the center of the device to function as stops for estab-- lishing the normal position of the handle lever 42.
  • Theflange 39 has the circular hole. 43 for rotatably receiving”.
  • the shaft 44, and the flange 38 has a D-shaped hole 45' which nonrotatably receives the shaft in one angular position.
  • the shaft 44 has a flat along one side indicated at 46, and a notch 47 intersecting one edge of the flat 46, as new best in FIGURE 1. The functioning of this portion of the structure will be clarified as the description of the mechanism proceeds.
  • a cam unit 48 is rotatably mounted on the shaft 44, and includes the opposit end-sections 49 and 50 interconnected by the bar 51.
  • the normal functioning of the cam member 48 is best illustrated in FIGURE 3. In; locked position, the end portions 49 and 50, together with the cross bar 51, extend across the tongue 22 to maintain the interengagement of the apertures 25 and 26 with the abutments 28 and 29.
  • the normal position of the cam unit 48 is determined as a result of the interaction of the cam spring 52 and the engagement of the stops 53-54 on the lever 42 with the surfaces 5556 on the cam unit 48
  • the action of the relatively light spring 52 is to apply a gentle rotary biasing action to the cam member 48 with respect to the lever.
  • This rotative resilience of the cam member with respect to the lever in one direction permits the insertion movement shown in FIGURE 5.
  • the insertion is accompanied by a movement of the tonque 22 of the buckle section over the top of the abutments, and this must be accompanied by a counterclockwise rotation of the cam member (as shown in FIGURE 5) which is sufficient to permit the tongue 22 to pass underneath the bar 51 and the end portions 49 and 50.
  • the action of the spring 52 can rotate the cam member 48 from the displaced condition shown in FIGURE 5 to that of the fully locked position shown in FIGURE 3. This action can take place without displacement of the lever 42.
  • the fixed end of the spring 52 is a portion of constricted diameter shown at 57 which conforms to the D-shaped cross section of the shaft 44, and closely embraces it in a non-rotative relationship.
  • the remainder of the spring 52 is rotatable with respect to the shaft 44.
  • the end 58 of the spring engages the cross bar 51 of the cam member as best shown in FIGURE 2.
  • the spring 59 also surrounds the shaft 44, and functions to bias the lever to the position shown in FIGURE 3, applying a counterclockwise torque, as shown in the drawings.
  • the spring 59 is similar in construction to the spring 52, except that it will normally be made of heavier wire to apply a stronger biasing action.
  • the fixed end of the spring consists of a portion of reduced diameter shown at 60 which conforms to the cross section of the shaft 44, and holds it securely in nonrotative relationship.
  • the opposite end of this spring 61 engages the edge of the abutment 62 which is integral with the lever 42, and extends from the panel portion 63 to a position close to the shaft 44, with insufiicient clearance for the free end 61 to slip out of engagement.
  • the abutment 64 is also preferable in this arrangement, and fully embraces the shaft 44 with freedom of rotation.
  • the abutment 64 is primarily for the purpose of maintaining the relative position of the abutment 62 and the shaft 44, and this structure is readily adaptable either to a die-cast or molded construction of the entire lever handle 42.
  • the metallic bearing inserts shown at 65 and 66 are recommended for insertion into the ends 67 and 68, which establish the pivotal mounting of the lever with respect to the shaft 44 (in conjunction with the abutment 64).
  • the surfaces 69 and 70 at the opposite ends of the lever 42, respectively, operate in conjunction with the lanced offsets 4t) and 41 to establish the normal angular position of the lever shown in FIGURE 3, against the action of the spring 59.
  • Recesses as shown at 71 in FIGURE 1 are associated with each of these shoulder surfaces 69 and 70 to provide clearance for rotation of the lever so that the stops 40 and 41 will not interfere with rotation of the lever to the release position.
  • the handle forces will then easily overcome the resistance against the rotation of the cam member, and the device .can be moved to the FIGURE 4 position to permit release of the buckle section 20 from the buckle section 30, It should be noted that the full release position of the lever 42 shown in FIGURE 4 represents a swinging movement beyond the perpendicular to a line connecting the belt terminals on the opposite buckle sections. This movement exceeds ninety degrees, in the preferred form of the invention, and carries the lever beyond the position where inertia forces would conceivably bring it.
  • the assembly of the device is interesting in one particular, and this deals with the establishment of the necessary initial torsion in the springs 52 and 59.
  • the procedure initially involves placing the lever so that the inserts and 66 are in axial alignment with the holes 43 and 45, and the shaft 44 may then be inserted through the hole 43 and the insert 65. At this point, the shaft 44 is engaged with the spring 52, with the end 58 properly hooked over the cross bar 51 of the cam unit. The angular position of the shaft 44 is selected for proper engagement with the fixed end 57, and the shaft is then forced through this portion of the spring and through the beari-ng hole in the abutment 64.
  • the shaft can then be given sufiicient turns in a clockwise direction to establish the desired initial torsion in the spring 52, with an additional amount of turns in a clockwise direction corresponding to the amount of initial set of the spring 59.
  • the shaft 44 may then be axially engaged with the end 61 of the spring 59, with the end 61 properly positioned with respect to the abutment 62.
  • the shaft Prior to the engagement of the shaft 44 with the flange 38, the shaft is rotated in a counterclockwise direction an amount corresponding to the initial torque of the spring 59.
  • the flat 4-6 of the shaft is then aligned with the D-hole 45, and the shaft 44 moved axially into engagement with the flange 30 to the point that the notch 47 will embrace the thickness of the flange.
  • the shaft is then released, and is thereby fixed against axial displacement in either direction.
  • the adjustable terminal assembly generally indicated at 75 is dissociated from the tongue 76 which is releasably locked to the buckle section 77.
  • the tongue plate 76 is connected to the adjustable terminal unit by a fixed length of belting shown at 78. It is preferable that a spacing of approximately eight inches be established between the terminal assembly 75 and the tongue plate 76, which normally places the terminal assembly far enough off the lap of the wearer so that it is no longer objectionable.
  • the fixed cylindrical bar 79 and the movable bar 80 correspond to the bars 33 and 34, respectively, shown in FIGURE 1.
  • the side flanges 81 and 82 serve the same function as the flanges 23 and 24 of the FIGURE 1 assembly, respectively.
  • the tension portion 83.0f the belt and the free end 84 are arranged in the same relationship as previously described.
  • the buckle section 77 is normally connected to the belt section 85, and contains a cam-type locking mechanism of the type shown and described in FIGURE 1 and the related views, with the exception that the handle lever 86 has a counterbalance feature in which a balance Weight 87 is added to bring the centerof gravity as close as possible to a plane containing the axis of the shaft 83, and which is perpendicular to the central plate portion '89 of the buckle section 77.
  • a balance Weight 87 is added to bring the centerof gravity as close as possible to a plane containing the axis of the shaft 83, and which is perpendicular to the central plate portion '89 of the buckle section 77.
  • the lanced portions '90 and 91 serve the same purpose as the portions 40 and 41 in IFIGURE l.
  • the flanges 92 and 93 are equivalent to the flanges 38 and 39, respectively, in FIGURE 1.
  • FIGURES l0 and 11 illustrate a modified form of the invention in which an aligned movement of the lever is provided by using a non-coaxial relationship between the cam member and the lever pivot.
  • the buckle section 94 has spaced side flanges 95 which position the D- shaped lever shaft 96, together with the lever-return spring 97.
  • the cam member 98 is rotat-ably mounted on the shaft 99, which is also positioned by the flanges 95, with the shaft 9'9 carrying the cam spring 100. In the position shown in FIGURE 10, the cam prevents the disengagement of the tongue plate 101 of the opposite buckle section from the abutments 102cm the plate portion 193 of the buckle section 94.
  • the handle 104 has spaced s-idefi-anges as shown at 105 received between the flanges 95, and a rod 106 is fixed with respect to the flanges 105.
  • Rotation of the handle 104 in a clockwise direction about the shaft 96 will carry the rod 106 upwardly, and the engagement of this rod with the extensions 107 on the cam member 98 will induce counterclockwise rotation to the release position shown in FIG- URE 11.
  • the edges 108 of the flanges 105 can be used as stops to establishing the full release position of the lever, with these edges disposed to engage the plate 103 in the release position.
  • Slots 109 may be provided in the flanges 95 to accommodate bars for an adjustable belt terminal, as described in connection with the views discussed previously.
