Definitions

  • the present invention relates to a vehicle body having a hinging device for a vehicle side door, in particular for the front doors of a motor vehicle .
  • the side doors of a motor vehicle are known to be attached to the body by means of pairs of hinges which are mounted at the level of the front post of the door opening occupied by each door ; the two hinges which support each door are normally fitted within the transverse bulk of the respective door opening, substantially coplanar with it, and within the longitudinal bulk of the door opening as well ; in practice, the hinges project internally cantilever within the door opening .
  • Such a position means that when the door is rotated to open the door opening, the door front edge , up to the waist line, enters the door opening ; this fact causes various drawbacks : first of all the wheather strip with which the door opening front post is equipped has to be interrupted over all the lower portion of the post, or below the waist line defined by the lower edge of the door windows ; otherwise, actually, the antifriction would interfere with the door front edge , preventing the door from opening . Moreover, this disposition forces to have a rather short distance between the hinges and consequently a body/door assembly of insufficient stiffness . On the other hand, the solutions known from DE-A-3537303 and DE-A-3341922 do not avoid these drawbacks.
  • the object of the present invention is to provide a vehicle body having a hinging device for the side doors which is of simple structure, which enables to use hinges internal to the vehicle body and obviates the aforesaid drawbacks and, in particular, which permits the extensive use of antifriction and is arranged to ensure a good structural stiffness .
  • the reference numeral 1 indicates overall a road vehicle of well-known type, in the present case a motor vehicle, of which only a portion of the front part is shown for simplicity ;
  • the vehicle 1 comprises a body 2 supported by wheels 3 ( of which only a front wheel, on the driver's side, is shown ), said body delimits within itself a passenger compartment 4, and respective side doors 5, of which only a front door, on the driver's die, is shown for simplicity, arranged to cooperate in the shutting with respective door openings 6 of the body 2, each being provided with a window 7 shut by a glass 8 a lower edge 9 of which delimits the " waistline " of the vehicle 1, ideal line which subdivides the glazed part delimiting the passenger compartment 4 from the rest of the body 2 .
  • Each door 5 is connected to the body 2 by means of a respective hinging device 10 which enables the door 5 to rotate, in relation to the body 2, towards the exterior of the vehicle ( and vice versa ) to let the door opening 6 free (occupy) in order to determine the opening ( shutting ) of the door to give ( prevent ) access to the passenger compartment 4.
  • the device 10 comprises a pair of internal hinges 12,14 of well-known type by means of which the door 5 is fastened to the body 2 ; said hinges 12,14 are fitted mutually coaxial in the transverse bulk (that is to say in the direction of the wheel gauge of the vehicle 1 ) of the door opening 6, substantially coplanar with said door opening 6, and are supported by a front post 18 of the door opening 6 by means of brackets 15, 16 .
  • the hinges 12, 14 are supported by the latter in an opposite position, that is to say placed outside the longitudinal bulk ( namely in the direction of the wheel base of the vehicle 1 ) of the door opening 6, laterally cantilever in relation to a front side edge 20 of the door 5 adjacent to the post 18 ; in particular, the hinges 12, 14 are fitted so as to present a relatively long distance between them and, to that end, the lower hinge 14 is fitted substantially flush with a lower edge 21 of the door 5, in an advanced position in comparison with the upper hinge 12, therefore the hinges 12, 14 are fitted at different distances from the door opening 6, the hinge 14 being closer to the front wheel 3 of the vehicle 1 in comparison with the upper hinge 12 .
  • the hinges 12, 14 are inclined in the plane of the door opening 6, so as to define a door rotation axis 25 which is oblique in relation to the vertical and downwardly diverging in relation to the door opening 6 and are placed forward in relation to the door opening 6, towards the front wheel 3, by an amount such as to determine ( Figure 3) the exit of the edge 20 out of the door opening 6, further to a rotation of the door indicated by the arrow, in such a direction as to translate said door from the position shown in full line to the one shown by a short dashes line, so as to let the door opening 6 open ; furthermore the hinges 12, 14 are also inclined in a plane perpendicular to the plane of the door opening 6 so that the axis 25 ( Figure 2 ) is inclined transverse to the door opening 6 ( and to the door 5 ), upwardly diverging in relation to said door opening, that is to say with the hinge 12 placed more towards the exterior of the vehicle in comparision with the hinge 14 .
  • the device 10 in accordance with the invention comprises, moreover, respective fastening brackets 32, 34 cantilever-fixed on the edge 20 to connect the door 5 to the respective hinges 12, 14, which obviously are of different length ; said brackets 32, 34 are housed, together with the hinges 12, 14, within an opening 38 provided in the body 2 alongside the post 18, on the side opposite the door opening 6, for example directly within the post 18, provided with suitable apertures to enable the brackets 32, 34 to pass through towards the interior of the door opening 6 .
  • the door 5 can be snap-locked and in a thrust-releasable manner in an intermediate position ( shown by short dashes ) and in an extreme position of maximum opening (show by dashes and dots ) by means of a stopping device 50, of well-known type, consisting of a cam lever 51 hinged on the post 18 and which is inserted into the door 5 through a slit 52, where it cooperates with a stopping roller 53 supported by a bracket 54 in a suitable position and arranged to snap-cooperate with two respective successive concavities 55 of the lever 51 .
  • the device 50 can possibly be integrated into the hinge 14 and the bracket 34 concerned which, owing to its oblong shape, lends itself to be substituted for the cam lever 51 .
