Definitions

  • This invention relates to a safety device for an automobile front hood, formed from a hook provided in addition to the hood fastening system.
  • hood fastening systems For safety reasons it is known to provide in front hood fastening systems further devices for restraining the hood.
  • the hood fastening system can be operated from the interior of the passenger compartment, whereas the safety device which restrains the hood and retains it in a semi-open position is operated from the exterior of the automobile. This is desirable to prevent the front hood rising while the automobile is moving, due to either an erroneous manoeuvre or a strong accidental impact.
  • the object of the present invention is to provide a safety device for the opening of the front or engine hood, which comprises a lever for its operation but which has the advantage of maintaining the lever hidden when the hood is closed whereas is able to automatically move the safety hook operating lever into an easily accessible region when the engine hood opening control is operated from the interior of the passenger compartment.
  • a front hood opening safety device of the type operable from outside the passenger compartment, comprising a support on which there is pivoted a safety hook which is retained by the force of a spring in a first predetermined position corresponding to complete closure of the hood, said hook having at one end the shape of a ramp which blends into a suitably shaped wall, on opening the hood said hook assuming a second position in which said ramp comes into engagement with a catch element, said hook being operationally connected to a control lever provided with a handgrip, said lever being characterised by being provided with at least one arm formed from at least one preloaded elastic element.
  • said control lever consists of at least one wire spring which is pivoted to said hook and of which the ends form arms, a first end being secured to the hook itself and a second end being secured to said handgrip.
  • said second end of said control lever with the relative handgrip remains constantly in contact with a wall on the front of the automobile.
  • said lever consists of a pair of wire springs, of which those ends secured to the handgrip are formed from a single wire.
  • the reference numeral 10 indicates overall a front or engine hood formed from an external sheet metal portion 11 with a relative internal stiffening sheet metal portion 12, and a radiator protection grille 13 which is also rigid with the hood 10.
  • the reference numeral 14 indicates a front bumper (partly shown), and 15 and 16 indicate sheet metal portions forming a front cross-member 17.
  • the sheet metal portion 16 comprises an aperture 18 provided with a catch element 19, the reference numeral 20 indicating a rivet which fixes the catch element 19 to the edge of said aperture 18.
  • the sheet metal portion 12 carries a support 21 which is fixed by a threaded pad 22 and a screw 23. With the support 21, which is of double-T shape in the figure, there are rigid two lugs 24 which are disposed perpendicular to the intermediate portion of said double-T and are provided with a hole 25. A pin 26 is inserted through said hole 25, and on it there is rotatably pivoted a hook 27 having an end ramp 41 which smoothly joins into an inclined wall 42.
  • Said hook 27 is retained in a predetermined position by a spiral spring 28 centrally wound about said pin 26 and having two arms 29 and 31 which engage respectively in a hole 30 provided in one of the lugs 24, and in a hole 9 in the hook 27.
  • Two seats 32 and 33 are provided in the hook 27, there being inserted in the seat 33 a pin 34 which by means of a split ring 35 retains coil turns 36 of a control lever indicated overall by 37.
  • the control lever 37 consists of a preloaded spring to which a handgrip 38 is rigidly connected.
  • the reference numeral 39 indicates two arms of the spring, which are engaged in the seats 32 of the hook 27, and the reference numeral 43 indicates further arms which are rigidly connected to the handgrip 38.
  • the reference numeral 40 indicates holes provided in the support 21 and used for fixing the support to the hood 10.
  • the hood 10 At the moment in which the hood 10 is released, an elastic system (not shown) tends to raise the hood and consequently also the safety device which comes into operation at this point. In this respect, in its upward movement, the hood 10 also carries with it the hood 27 which is retained against the catch element 19 by the action of the spring 28.
