Definitions

  • the present invention relates to an improved arrangement for actuating motor vehicle door locks whereby, a closure of one of the locks generally at the front, is automatically accompanied by a closure of all other locks.
  • This arrangement comprises a door lock actuation shaft projecting from a box housing and moving between the up and down positions.
  • the movement of the shaft is controlled by an electro-motor through a kinematic chain comprising a releasable flexible pawl connecting with the shaft, which is pinned to a slide integral with the shaft and operates in conjunction with a cursor through two operative faces co-acting with a respective pair of faces on the said cursor and a third face co-acting with two surfaces of the said slide.
  • End stop means operate in conjunction with the said cursor and the said slide.
  • the general purpose of the present invention is to achieve an arrangement able to satisfy the further requirements quoted above and, to that effect, according to the invention an actuation arrangement has been conceived for motor vehicle door lock closure centralised systems of the type comprising a shaft (13) actuating the door lock projecting from a box housing (11) and moving between the up and down positions, an electro-motor (16) controlling the movement of the said shaft (13) through a kinetic chain comprising a releasable flexible pawl (20) connecting with the shaft (13), characterised in that the said pawl (20) is engaged in a slide (12) integral with the shaft (13) and cooperates with a cursor (19) through a first pair of operative faces (27,28) co-acting with a respective pair of surfaces (29,30) on the said cursor, the said pawl (20) also having a second pair of operative faces (31,32) cooperating with a leaf spring (26) located between the pawl (20) and a seating (25) in the said slide (12), so that when the shaft
  • the actuating arrangement referred to here bears reference number 10 and consists structurally of a box 11 inside which is mounted a slide 12 integral with a control shaft 13, projecting through a guide channel 14, and connecting in a known manner with the door lock.
  • a screw 15 is also located so as to rotate under the control of an electro-motor 16 through a pair of gears 17,18.
  • the screw 15 and gear 18 are preferably (Fig.3) moulded as a single plastic material component with the advantage of precision and cost, and furthermore by means of the metal core 36, the diameter of the screw may be particularly limited in favour of the system performance which can develop a high thrust load.
  • the said screw 15 is functionally connected with slide 12, in a releasable manner as will be explained, by means of a cursor 19 and a pawl 20, which are respectively linked to screw 15 and slide 12.
  • the cursor 19 is coupled to the screw 15 by means of a lead screw 21 and its movement along the screw is guided by a tongue 22 coupled within a channel 23 (Fig.5).
  • the pawl 20 engages as a rider on pins 24 of one piece between a seating 25 for slide 12 and its rotation is typically braked by a leaf spring 26 acting between the pawl itself and the bottom wall of the seating 25.
  • the pawl 20 also has two operative faces 27,28 intended to cooperate with a respective pair of faces 29,30 on the cursor 19, and two surfaces 31,32 cooperating with the leaf spring 26, as will be explained, to define the two extreme positions of slide 12.
  • Operation of the arrangement described above may be controlled by means of a centralised unit to which are connected all the arrangements for the motor vehicle door.
  • the control circuit may be of whatsoever type suited to the purpose.
  • the system is also economical since the leaf spring 26 can be produced from sheet in an extremely simple manner.
  • pins 24 for pawl 20 recessed of one piece from the body of the arrangement eliminate a component and the relevant assembly operation.
