  • FIG. 6 is a section view on the line VIIVII in FIG. 7, of another embodiment of a hinge according to the invention which is suitable for adjustable motor car seats.
  • FIG. 7 is a sectional view of the hinge on the line VI-Vl in FIG. 6.
  • the hinge comprises a pair of hinge members, I, 2 which are rotatable relative to each other about hinge axis XX and which are adapted to be secured to the load carrying seat part (not shown) and the adjustable back rest (not shown) of a motor vehicle seat.
  • Hinge members 1, 2 present plate-like, pivotally connected inner end portions la, 20, which are located face to face to each other, the inner end portion 2a of hinge member 2 being of annular formation with an axial bore therethrough.
  • Circular pivot ring 11 is located face to face with hinge member 1 and is rivetted to it by means of rivets 59.
  • Circular guide plate 4 has a diameter which is slightly smaller than the outer diameter of pivot ring 11 and is located face to face with pivot ring 11 in concentric relationship therewith.
  • Guide plate 4 is also rivetted to hinge member 1 by means of rivets 59 so that both pivot ring 1 l and guide plate 4 are fast with hinge member 1.
  • the outer peripheries of pivot ring 11 and guide plate 4 present radially outwardly directed bearing surfaces to form a spigot-like pivot formation A of stepped configuration as shown in FIG. 2.
  • Circular gear ring 6 presents around part of its inner periphery an arcuate toothed rack of concave configuration with a set of teeth 6a which are directed radially inwardly towards hinge axis XX.
  • Gear ring 6 is located face to face with the inner end portion 2a of inner end of hinge member 2 an annular mounting head B with a bore passing axially therethrough.
  • Gear ring 6 is therefore rotatable with hinge member 2 relative to hinge member ll about hinge axis XX.
  • the outer periphery of guide plate 4 is complementary with the inner periphery of gear ring 6 along the peripheral zone 58. Except in the region of radial slot 4a in guide plate 4, the tips of teeth 6a along the arcuate rack portion of gear ring 6, are also complementary .with and mates with the outwardly directed bearing surface presented by the outer periphery of guide plate 4 along peripheral zone 58.
  • the outer periphery of guide plate 4 is complementary with part of the bore 60 through mounting head B on hinge member 2.
  • the outer periphery of pivot ring 11 is complementary with and mates with the inwardly directed bearing surface presented by the bore through the annular, plate-like end formation 2a on the inner end of hinge member 2.
  • pivot ring 1 l is complementary to part of the bore through mounting head B on the inner end of hinge member 2.
  • Mounting head B on hinge member 2 with its stepped bore 60 is rotatably carried on pivot formation A which is fast with hinge member 1, so that the two hinge members 1, 2 are rotatable relative to each other.
  • Cover plate 3 which is located face to face with guide plate 4 and overlies gear ring 6, is also rivetted to hinge member l by means of rivets 59, thereby to hold the assembly firmly together.
  • Locking element 7 with a series of outwardly directed locking teeth 7a which are complementary to the locking teeth 6a of the arcuate rack presented by gear ring 6 and which extend circumferentially along the arc of a circle, is slidably mounted in radial guide slot 4a in circular guide plate 4 which is fast withhinge member 1.
  • Locking element 7 is thus radially but not circumferentially movable relative to hinge member 1 and is interengageable with the teeth 6a of the arcuate rack which is fast with hinge member 2, in any one of a plurality of circumferentially spaced positions, thereby to lock the two hinge members 1, 2 together in any one of a plurality of angular positions relative to each other.
  • Actuating means for locking element 7 comprises a single rotary actuating member 5 in the nature of a circular cam plate which is concentrically located within pivot ring 111 between hinge member 1 and guide plate 4 for concentric rotation about hinge axis XX and which is splined to operating shaft 12 at l2b (see FIG. ll) for rotation therewith.
  • Operating shaft 12 is co-axial with hinge axis XX.
  • Rotary cam plate 5 is operatively coupled to locking element 7 by means of a single curved cam follower 7b projecting from locking member 7 and engaging in curved slot 5a in cam plate 5.
  • Opposite sides of slot 5a present two opposed arcuate cam surface zones 61, 62 (see FIG.
  • cam follower 7a presents an arcuate bearing surface zone 63, 64 for each cam surface zone 61, 62 respectively.
  • Shaft 12 is rotatably located in central apertures in hinge member 1, guide plate 4 and cover plate 3. Shaft 12 is fast with manipulating knob 19. Rotation of knob 19 causes rotation of shaft 12, thereby to rotate cam plate Sand cause radial movement of locking element 7.
  • the teeth 6a of the arcuate rack of concave configuration presented by I gear ring 6, extend round part of the periphery of the bore 60 through mounting head B on hinge member 2. It will be seen that the toothed arcuate rack lies along a circumferential zone disposed radially in the vicinity of the outwardly directed bearing surfaces presented by pivot formation A on hinge member 1.
  • Pivot ring 11 also acts as a spacing or locating element which is located face to face with guide plate 4 and locking element 7 contained in radial slot 4a, to ensure that the toothed locking element 7 lies in the same plane as the toothed arcuate rack presented by gear ring 6, thereby to ensure smooth engagement and disengagement between locking element 7 and the arcuate rack. It will be appreciated that by utilizing pivot ring 11 to constitute a pivot formation and also to act as spacer means, the number of different parts required for the hinge can be reduced, thereby to simplify construction and improve compactness. Compactness is improved further by locating the rotary actuating cam plate 5 and its follower 7b in the bore through pivot ring 11.
  • Circular guide plate 4 not only guides locking element 7 for radial movement into and out of engagement with the arcuate toothed rack presented by gear ring 6 and restrains locking element 7 against circumferential movement relative to hinge member 1, but also constitutes a pivot formation on which hinge member 2 is rotatably mounted. This improves the rigidity and strength of the hinge.
  • guide plate 4 By locating guide plate 4 within gear ring 6 and rotatably mounting gear ring 6 on guide plate 4, a compact construction with a minimum number of parts can be obtained.
  • the arcuate rack presented by gear ring 6 By arranging for the arcuate rack presented by gear ring 6 to lie along a'circumferential zone disposed radially in the vicinity of the bearing surfaces between the two hinge members 6 l, 2, certain parts can'be utilized to serve pose.
  • camsurface zone 61 and the associated bearing surface zone 63 which are engaged when locking element 7 is urged into engagement with the arcuate rack are complementary to one another. This prevents binding of the engaging parts and permits smooth and positive operation. If required, the cam surface zone 62 and its associated bearing surface zone 64 which are engaged when locking element 7 is urged out of engagement with the arcuate rack, may also be complementary to one another.
  • Locking element 7 is resiliently biased towards engagement with the teeth 6a of gear ring 6 by means of coil spring 53 embracing shaft 12.
  • the one end 53a of spring 53 is located in a slot or kerf 65 extending diametrically through shaft 12.
  • the other end 53b of spring 53 engages anchor 54 fast with cover plate 3 which, in turn, is fast with hinge member 1. This biases shaft 12 and actuating cam plate 5 for rotation relative to hinge member 1 to urge locking element 7 radially outwardly into engagement with the arcuate rack.
  • Anchor 54 comprises a formation stamped out of cover plate 3 to extend away therefrom.
  • the two hinge members 1, 2 are resiliently biased by coil spring 17 towards a position in which their angular displacement is zero.
  • the outer end of spring 17 engages anchor 55 fast with hinge member 2.
  • the inner end of spring 17 engages anchor formation 66 stamped out of cover plate 3 and extending away therefrom. Since cover plate 3 is fast with hinge member 1, the inner end of spring 17 is in effect anchored to hinge member 1.
  • FIGS. 6 and 7 the embodiment illustrated in these two drawings is similar in construction to that illustrated in FIGS. 1 to 5 with theexception of the actuating means for locking element 7.
  • the actuating means for locking element 7 comprise a single rotary actuating member 50 in the nature of a circular plate which is eccentrically mounted on shaft 12 for rotation about hinge axis X-X and which is splined to shaft 12 at 12b for rotation therewith.
  • Eccentrically mounted actuating member 50 is operatively coupled to locking element 7 by means of a single cam follower comprising annular coupling link 51 which is rotatably mounted on actuating member 50 and which is pivotally connected to locking element 7 by means of pivot pin 52 which is rotatably connected to projection 51a on coupling link 51.
  • actuating member 50 constitutes two adjacent arcuate cam surface zones 67, 68 each of which is disposed about hinge axis X-X and is complementary to its own associated bearing surface zone 69, 70 respectively presented by the inner periphery of coupling link 51. It will be seen from FIG. 6 of the accompanying drawings that actuating member 50 and coupling link 51 are located in the same plane as hinge member 2 and pivot ring 1 1 and are both located within the bore of pivot ring 11 and the bore in hinge member- 2, in a position between hinge member 1 and guide plate 4.
  • the teeth 7a on locking element 7 may be moved into and out of engagement with the teeth 6a of the arcuate rack presented by gear ring 6, by rotation of shaft 12 in opposite directions.
  • Rotation of shaft 12 causes rotation of eccentrically mounted actuating member 50 within coupling link 51, thereby to displace coupling a dual purlink 51 in a radial direction and move locking element 7 radially into or out of engagement with the arcuate rack.
  • Shaft 12 can be rotated by manipulation of knob 19 which is fast with the outer end of shaft 12.
  • eccentrically mounted actuating member 50 engages either one of the two adjacent cam surface zones 67, 68 presented by the outer periphery of actuating member 50 with an associated bearing surface zone 69, 70, respectively presented by the inner periphery of coupling link 51.
  • Each of the two cam surface zones is complementary to its bearing surface zone. It will be seen that the two arcuate cam surface zones are presented by a single surface.
  • the configuration and/or dimensions of the inner periphery 11a of pivot ring 11 are such as to permit radial movement of coupling link 51 in the same direction as the required radial movement of locking element 7 within guide slot 4a, as well as radial movement in a transverse direction.
  • Coupling link 51 is located within pivot ring 11 with sufficient clearance to accommodate the radial movement of the coupling link 51 which is necessary to cause the. required radial displacement of locking member 7 into and out of engagement with the arcuate rack presented by gear ring 6, when actuating member 50'is rotated.
  • Pivot ring 11 is open at its upper end at 11b in registration with guide slot 4a in guide plate 4, to accommodate projection 51a on coupling link 51.
  • a hinge according to the invention is simple in construction yet effective in operation. Once the two hinge members 1, 2 are locked together, they can only be unlocked by a radially inward displacement of teeth 7a on locking element 7 away from teeth 6a on gear ring 6. In the arrangement illustrated in FIGS. 1 to of the drawings, disengagement of locking teeth 6a, 7a can only be effected by rotation of cam plate 5. Pressure on the hinge members 1, 2 cannot cause unlocking, as the angle of curved slot 5a in cam plate 5 is such that it resists radially inward displacement of locking element 7, thereby to prevent accidental disengagement of the locking teeth 6a, 7a. This enhances the safety of a hinge according to the invention.
  • a hinge according to the invention can be made very compact and is relatively inexpensive to produce. Rattling of the component parts can be eliminated altogether or at least reduced to a minimum, particularly where biasing springs such as 17 and 53 are provided.
  • a pair of hinges according to the invention may be provided on opposite sides of a seat with an adjustable back rest.
  • a single handle, knob or other suitable manipulating means may be provided at one of the hinges, such manipulating means being suitably coupled, such as by means of a common operating shaft, to both of .the hinges so that operation of the common manipulating means causes actuation of both hinges.
  • each hinge may be provided with an axially extending bore of rectilinear cross-sectional configuration as shown in FIGS. 6 and 7, the bore being adapted to receive a complementary coupling rod 56, which, in turn, is

It is contemplated that there might be applications where the actuating member and the cam follower do not lie wholly within a bore in one of the hinge members but only partially in a bore in at least one of the hinge members. It is also possible for only the rotary actuating member to be located at least partially within a bore in at least one of the hinge members.
  • the bearing surface presented by pivot ring 11 is slightly larger in diameter than the bearing surface presented by guide plate 4, so that the bore 60 through the mounting head B on hinge member 2 is stepped. This relationship may be reversed. It is also possible for the two bearing surfaces to be of substantially the same diameter so that the bore 60 through the mounting head B is of constant diameter throughout its length in an axial direction.
