  • a hinge assembly for a door structure of an automotive vehicle comprising a door-side hinge bracket mounted on a body structure defining an Opening for f the door structure, a door-side hinge bracket mounted on the door structure, a hinge pin fixedly mounted-on the door-side hinge bracket and pivotally supported on the body-side hinge bracket, a cam member having recessed flanks which correspond respectively to closed, half-open and fully-open positions of the door structure, and a torsion spring which is anchored at its ends to the body-side and door-side hinge brackets 1 and which is engageable with any of the three recessed flanks of the cam member depending upon the rotational position of the door structure and accordingly the hinge pin and the cam member about an axis of the hinge pin.
  • the present invention relates generally to body structures of automotive vehicles and, particularly, to a door structure of an automotive vehicle. More particularly, the present invention is concerned with a hinge assembly for the door structure of an automotive vehicle and, still more particularly, with a door hinge assembly of the two-stage checking type which is capable of holding the door structure in two different positions, viz., halfopen and fully-open positions when the door structure is open.
  • a conventional door hinge assembly of the two-stage checking type usually comprises a body-side hinge bracket which is fixedly mounted on a vehicle body structure defining an opening for receiving the door structure.
  • the body-side and door'side hinge brackets are pivotally connected together by a hinge pin which provides an axis of turning of the door structure relative to the vehicle body when the door structure is being moved from a closed position to a half or fully open position or vice versa.
  • the door-side hinge bracket carries thereon two cam rollers of a cam member having two cam lobes, the cam rollers or cam lobes partly projecting beyond the foremost end of the door side hinge bracket.
  • a torsion spring is anchored at one end to the body-side hinge bracket and at the other to the door-side bracket and is engageable with either of the two cam rollers or of the two lobes of the cam member depending upon the rotational position of the door structure about the pivotal pin.
  • the torsion spring is thus operative to bias the door structure into the halfopen or fully-open position when the door structure is open and accordingly one of the cam rollers or one of the lobes of the cam member is brought into rolling or sliding engagement with the torsion spring.
  • the cam rollers or the lobes of the cam member on the door-side hinge bracket be located at considerably large spacings from the hinge pin so that sufficient moment of force will be imparted to the door structure about the hinge pin when the cam roller or the cam lobe on the door-side hinge bracket is in engagement with the torsion spring.
  • the body-side and door side hinge brackets, the hinge pin and the torsion spring are assembled together prior to the mounting of the door structure on the body structure and the hinge assembly thus constructed is bolted to the door and body structures of the vehicle when in assembling the door structure onto the body structure. Because of the limited space available between the door and body structures, extremely timeconsuming and laborious operations are involved in bolting the hinge assembly to the door and body structures.

  • an automotive vehicle has a door structure 10 is hingedly connected at its front end to a body structure 12 through door hinge assemblies 14 which are shown as two in number.
  • the door hinge assembly 14 of the prior art two-stage checking type comprises a body-side hinge bracket 16 having upper and lower flange portions 18 and 20, respectively and a door-side hinge bracket 22 having upper and lower flange portions 24 and 26, respectively.
  • the body-side hinge bracket 16 is fixedly mounted on, for example, an outer member 28 of a front pillar 30 forming part of the body structure 10 of the vehicle by means of bolts which are commonly designated by reference numeral 32, whereas the door-side hinge bracket 22 is fixedly mounted on a front end cross member 34 of the door structure 12 by means of bolts which are commonly designated by reference numeral 36.
  • the upper and lower flange portions 18 and of the body-side hinge bracket 16 are formed with apertures 38 and 40, respectively, and likewise the upper and lower flange portions 24 and 26 of the door-side hinge bracket 22 are formed with apertures 42 and 44, respectively. These apertures 38, 40, 42 and 44 are vertically aligned with one another and receive therein hinge pin 46, as seen in FIG. 3.
  • the door-side hinge bracket 22 is thus pivotally connected to the body-side hinge bracket 16 by the hinge pin 46 so that the door structure 12 is rotatable about the hinge pin 46 relative to the body structure 10.
  • the door-side hinge bracket 22 carries on its upper flange portion 24 .
  • two cam rollers 48 and 50 which are rotatable about axes which are parallel to the hinge pin 46 and which partly project forwardly of the front end of the upper flange portion 24.
  • the upper and lower flange portions 18 and 20 of the body-side hinge bracket 16 are further formed with recesses 52 and 54, respectively, which are vertically aligned with each other, s slot 56 which is located in the path of the revolution of the cam rollers 48 and 50 about the hinge pin 46, and a recess 58 which is in diametrically opposed relation to the slot 56 across the vertically aligned recesses 52 and 54.
  • a torsion spring 60 has a bar portion 60a which is received in the vertically aligned recesses 52 and 54 and end portions 60b and 60c which are turned in opposite directions and which are received in the slot 56 and the recess 58, respectively. The torsion spring 60 is thus carried on the body-side hinge bracket 16 in a preloaded condition.
  • the door structure 1S and the door-side hinge bracket 22 are rotated about an axis of the hinge pin 46.
  • the cam roller 48 is brought into rolling engagement with the upper turned end portion 60b of the torsion spring 60 against the preload force of the torsion spring 60.
  • the door-side hinge bracket 22 is in a position having the cam rollers 48 and 50 holding the upper turned end portion 60b of the torsion spring 60 therebetween so that the door-side hinge bracket 22 is biased by means of the torsion spring 60 into the position holding the door structure 12 in the half-open position.
  • the doorside hinge bracket 22 is rotated in a reverse direction about the axis of the hinge pin 46 so that the roller 48 or the rollers 48 and 50 are for a second time brought into rolling engagement with the upper turned end portion 60b of the torsion spring 60 until they ride past the turned end portion 60b and restore the initial positions shown in FIGS. 2 and 3.
  • the cam rollers 48 and 50 may be replaced with a cam member (not shown) having two cam lobes which project from the door-side hinge bracket 22 to provide a general configuration similar to the contour described by the front end of the door-side hinge bracket 22 and projecting portions of the two cam rollers 48 and 50.
  • the cam rollers 48 and 50 on the door-side hinge bracket 22 be located at considerably large spacings from the axis of the hinge pin 46 so that the door-side hinge bracket 22 is given a sufficient moment of force about the axis of the hinge pin 46 by the torsion spring 60, as previously mentioned.
  • Such arrangements of the cam rollers 48 and 50 result in an increased fore-and-aft length of the upper flange portion 24 of the door-side hinge bracket 22 carrying the cam rollers 48 and 50 and accordingly in an enlarged overall construction of the door-side hinge bracket 22.
  • the enlarged construction of the door-side hinge bracket 22 not only results in an enlarged construction of the hinge assembly as a whole but in a limited space available for accommodating the rotational movement of the door-side hinge bracket 22 about the hinge pin 46, imposing serious restrictions on the layout of the hinge assembly and accordingly on the design of the body and door structures 10 and 12 of the vehicle. From the view point of production of the hinge assembly, the increased length of the upper flange portion 24 of the door-side hinge bracket 22 will further result in an increased production cost of the hinge bracket 22.
  • the body-side and door-side hinge brackets 16 and 22, the hinge pin 46 and the torsion spring 60 are usually assembled together prior to the mounting of the door structure 12 on the body structure 10 during production of the vehicle.
  • the hinge assembly thus constructed by the hinge brackets 16 and 22, the hinge pin 46 and the torsion spring 60 is mounted on the body and door structures 10 and 12 by the bolts 32 and 36 when the door structure 12 is being assembled onto the body structure at a final stage of the vehicle production line. Difficulties are encountered in thus bolting the hinge assembly to the body and door structures 10 and 12 because of the limited space available between the body and door structures.
  • the goal of the present invention is to eliminate all the above mentioned drawbacks that are inherent in the prior art two-stage checking door hinge assembly having the construction thus far described.
  • the two-stage checking door hinge assembly embodying the present invention comprises a body-side hinge bracket 62 having upper and lower horizontal portions 64 and 66, respectively, and a door-side hinge bracket 68 having upper and lower horizontal portions 70 and 72, respectively.
  • the body-side hinge bracket 62 is formed with holes 74 (FIG. 6) and is fixedly mounted on, for example, the outer member 28 of the front pipper of the vehicle body structure 10 by means of bolts 76 passed through the holes 74 and nuts 78.
  • the doorside hinge bracket 68 is formed with holes 80 and is fixedly mounted on the front end member 34 of the door structure 12 by means of bolts 82 passed through the holes 80 and nuts 84.
  • the upper and lower horizontal portions 64 and 66 of the body-side hinge bracket 62 have outer end portions which are adjacent to inner faces of front end portions of the upper and lower horizontal portions 70 and 72, respectively, of the doorside hinge bracket 68.
  • the upper and lower horizontal portions 64 and 66 of the body-side hinge bracket 62 have apertures 86 and 88 formed in their respective outer end portions and, likewise, the upper and lower horizontal portions 70 and 72 of the door-side hinge bracket 68 have apertures 90 and 92 in their respective front end portions.
  • These apertures 86, 88, 90 and 92 are vertically aligned together as best seen in FIG. 5 and the aperture 90 in the upper horizontal portion 70 of the door-side hinge bracket 68, in particular, is formed with axial serrations for the reason to be explained later.
  • a hinge pin 94 is inserted through these vertically aligned apertures in the upper and horizontal portions of the body-side and door-side hinge brackets 62 and 68.
  • the hinge pin 94 has an axially serrated upper end portion 96 which engages the serrations of the aperture 90 in the upper horizontal portion 70 of the door-side hinge bracket 68.
  • the hinge pin 94 is thus splined to the door-side hinge bracket 68 through the engagement between the serrations of the aperture 90 in the upper horizontal portion 70 of the bracket 68 and the serrations of the upper end portion 96 of the hinge pin 94.
  • the hinge pin 94 is permitted to rotate about its axis relative to the body-side hinge bracket 62, the door-side hinge bracket 68 is prevented from being rotated about the axis of the hinge pin 94 or, in other words, the door-side hinge bracket 68 and the hinge pin 94 are bodily turned about the axis of the hinge pin 94 relative to the body-side hinge bracket 62 when the door structure 12 is turned about the axis of the hinge pin 94.
  • the hinge pin 94 is prevented from being axially moved relative to the body-side and doorside hinge brackets 62 and 68 by means of a generally C-shaped ring 98 which is received in a circumferential groove 100 (FIG. 6) formed in a lower end portion of the hinge pin 94 projecting downwardly from the aperture 92 in the lower horizontal portion 72 of the doorside hinge bracket 68 (FIG. 5).
