Definitions

  • the present invention relates to a handle group for a vehicle door provided with a safety releasing system from the door locking means, for example consisting of a lock, so as to avoid the door from accidentally opening in case of side crash of the vehicle.
  • the grip In case of a side crash of the vehicle, however, the grip may be rotated by the inertia forces, thus releasing the lock and causing the door to open with severe danger for the passengers.
  • the grip In order to avoid this drawback, in the handle group according to EP 1950366, the grip is normally disconnected from the rotating body and integrally provided with a safety lever carried on the back of the grip so as to be pressed by the user during the manual rotation of the grip; the safety lever controls a coupling lever which only at this point, i.e. with the safety lever beign manually pressed, connects the grip to the rotating body, thus allowing the door locking means to be manually released, but not to be accidentally released due to a side crash.
  • the described handle group is however relatively complex and expensive to be manufactured, and may imply operating difficulties during manual opening.
  • the present invention thus relates to a handle group for a vehicle door, as defined in claim 1.
  • the handle group comprises a support fixable to the door, a grip carried by the support in a tilting manner between a resting position, in which the grip lays substantially parallel to the support, and a working position in which the grip is rotated with respect to the support, so as to be arranged with at least a first end thereof away from the support, a control body carried by the support so as to rotate between a locking position, in which it is adapted in use to keep the respective door locking means engaged, and an unlocking position in which it is adapted to disengage the door locking means; and one arm operatively connected to the first end of the grip to rotate the control body to the unlocking position when the grip is in the working position.
  • the control body is split into several elements and, in particular, comprises: a first and a second element pivotally mounted, independently of each other, on the same first axis and against the bias of first elastic means, one of the elements being operatively connected to the arm and the other being operatively connected in use to the locking means; and means for selectively constraining and releasing the first and second elements to/from each other, and comprising a mass pivotally carried by the first element about a second axis parallel to the grip, where said selective constraining/ releasing means are arranged so that the mass is free to rotate, in use, towards the grip to release the first element from the second element.
  • the mass is an eccentric mass with respect to the second axis.
  • the invention further relates to a vehicle door provided with the handle group according to the invention .
  • the grip which is made of synthetic plastic material, as well as the first and second elements of the control body, is normally always connected to the Bowden cable connected to the door lock, whereby the manual opening of the door is free from difficulties.
  • the eccentric mass particularly consisting of a third L- shaped element of the control body made of a metal alloy, is subjected to an inertial effect which is higher than that of the grip, the acceleration applied to the vehicle and therefore to the handle group being egual, transversally to the first and second axes, which are normally parallel; therefore, the mass rotates before the grip, disconnecting the first element of the control body from the second element; when the grip is also rotated by the inertia forces, it only rotates the element of the two elements of the control body to which it is operatively connected by means of the arm, while the other, connected to the Bowden cable which actuates the door locking means remains open, thus preventing the door from accidentally opening.
  • FIG. 1 shows an axonometric, three-quarters back view of a handle group for a vehicle door made according to the invention, depicted in a first configuration of use;
  • figure 2 shows the same view as figure 1, with parts removed, of the handle group of the invention depicted in a second configuration of use;
  • figure 3 shows a detail on enlarged scale, seen in the perspective three-quarters front view of the handle group in figure 1;
  • FIG. 4 and 5 show the handle group according to the invention, depicted in a third configuration of use, in a front perspective view and from different angles.
  • numeral 1 indicates as a whole a handle group for a door 2 of a vehicle, known and not shown.
  • Handle group 1 comprises a support 3, only diagrammatically shown in figure 1, mostly transparently, which may be fixed in a known manner to door 2, and a grip 4 carried by support 3 in a tilting manner between a resting position, shown in figure 1, in which grip 4 lays substantially parallel to support 3, and a working position, shown in figure 2, in which grip 4 is rotated with respect to support 3 so as to be arranged with at least a first end 5 thereof away from support 3, only one known element 6 of which is shown in figure 2, intended to accommodate a key latch (known and not shown for simplicity) in a through seat 7, adapted to prevent the rotation movement of grip 4, keeping its end 5 restrained to element 6.
  • a support 3 only diagrammatically shown in figure 1, mostly transparently, which may be fixed in a known manner to door 2
  • a grip 4 carried by support 3 in a tilting manner between a resting position, shown in figure 1, in which grip 4 lays substantially parallel to support 3, and a working position, shown in figure 2, in which grip 4 is rotated with respect to support 3 so
  • Handle group 1 further comprises a control body 8 carried by support 3 so as to rotate about an axis A defined by a pin 9 integrally carried by support 3 in a known manner: in particular, body 8 pivots about axis A between a locking position, shown in figure 1 and in which it is adapted in use to keep the respective (known) door locking means 10 engaged in a known manner, shown by a block only for simplicity, and an unlocking position, shown in figure 2, which is rotated with respect to the position in figure 1 in the direction of the arrow in figure 2, in which body 8 is adapted in use to disengage the door locking means 10, in this case due to pulling, upon the rotation of body 8, of a (known) Bowden cable 11, which connects in use the means 10 to body 8, tangentially thereto.

  • Handle group 1 finally comprises one arm 12, operatively connected to the first end 5 of the grip 4, in this case integrally obtained in one piece with the same, so as to protrude towards and through support 3, perpendicularly to grip 4, for rotating, as explained below, the control body 8 to the unlocking position, i.e. to the position in figure 2 starting from the position in figure 1, when grip 4 is in the working position, i.e. is manually subjected by a user to a direct traction in the arrow direction in figure 2.
  • control body 8 is divided into several elements which are independent of one another and in particular comprises a first element 13 and a second element 14 pivotally mounted, independently of each other, on the same axis A, being idly engaged, side-by-side, on pin 9, and opposed in their possibility of rotating from the position in figure 1 to that in figure 2, by first preloaded elastic means 15, adapted to normally keep both elements 13 and 14 in the position in figure 1, in which the Bowden cable 11 is not pulled.
  • any one of the elements 13 and 14 of body 8 is operatively connected to the arm 12 and not to the Bowden cable 11, while the other element is operatively connected, in use, to the locking means 10 by means of the Bowden cable 11 and is not directly connected to arm 12 in any way.
  • the first element 13 has a first fork- shaped end 16, which is engaged by the arm 12, and a second end 17, opposite to end 16, pivoted to the support 3, in particular to pin 9, so as to rotate about axis A.
  • the second element 14 is operatively associated, in a known manner, with the Bowden cable 11 connectable in use to the door locking means 10, in particular by means of its ears 18 (figure 5), radially and overhangingly protruding from element 14 with respect to axis A.
  • Control body 8 further comprises means, indicated by numeral 19 as a whole, for selectively constraining and releasing the first element 13 and the second element 14 to/from each other, comprising a mass 20 (figure 3) pivotally carried by the first element 13 about a second axis B parallel to grip 4, and in this case shown, to the first axis A: the selective constraining/releasing means 19 are further arranged, as explained below, so that the mass 20 is free to rotate in use about axis B and towards grip 4 for releasing the first element 13 from the second element 14.
  • mass 20 is an eccentric mass with respect to the second axis B and consists (figures 3, 4, 5) of a third L-shaped element 21, made of a metal alloy (e.g. ZAMA) , while grip 4, elements 13 and 14, and support 3 are all made by molding a synthetic plastic resin .

  • the second axis B is parallel to the first axis A and is arranged between the latter and the arm 12, while the length of the first arm 22 of the third L-shaped element 21 is such that the second arm 23 thereof is always arranged further away from the arm 12 than the first axis A defined by pin 9.
  • second elastic means 25 operatively associated with element 21, which are arranged at the second axis B and having a preset stiffness such as to normally make element 21 angularly integral with the first element 13 while allowing, due to elastic yield, a relative rotation between the elements 21 and 13 when element 21 is subjected to an acceleration T (indicated by the arrow in figure 4) of preset entity and transversal to the second axis B, e.g. because of a side crash experienced by the vehicle, the door of which is provided with group 1.
  • the second elastic means 25 may comprise a Belleville washer mounted to pin 24 so as to elastically press element 21 against a lateral side of element 13 opposite to element 14, so as to normally keep the elements 21 and 13 angularly integral by friction.
  • element 21 if element 21 is urged to rotate with respect to element 13 in the arrow direction in figure 4, if the stress exceeds the force exerted by spring 25, element 21 may rotate with respect to element 13 about axis B against the bias of the elastic means 25, which elastically yield, indeed, thus allowing such a movement.
