Definitions

  • latching assemblies typically allow a vehicle covering assembly to adopt one of three positions; locked, ajar or latched; and open.
  • One prior art latching assembly is disclosed in US 5,738,393 in which a safety hook is released by a second movement of a release pawl. In order to achieve this, a lost motion mechanism is provided between a safety hook, a catch claw and the release pawl.
  • the safety hook comprises a first surface to constrain movement of the striker and an abutment surface
  • the catch claw comprises a recess to restrain movement of the striker, a surface to drive the striker, a first lug including an outer surface and an abutment surface
  • the release pawl comprises a recess for engagement with the first lug of the catch claw, a nose and a radially extending member.
  • Figure 2 shows a side sectional view of the latching assembly of Figure 1 in a second, latched or ajar position
  • FIG. 1 there is shown a side sectional view of a latching assembly according to the present invention in a first position.
  • the first bracket is provided with a spigot 14 on which the safety hook is mounted for rotation about a first axis.
  • a bushing may be provided between the spigot and the safety hook.
  • the spigot is mounted generally centrally on the first bracket.
  • the spigot may be mounted to the bracket according to any suitable means.
  • the safety hook 4 is biased to rotate in an anticlockwise manner as shown in the Figures. Conveniently the safety hook is biased by spring means 5 ( Figure 4).
  • the safety hook comprises first and second safety hook members.
  • the release pawl 8 comprises two members extending radially from the third axis.
  • a first release pawl member 54 extends radially from the second spigot 40, is generally hook shaped and includes a recessed surface 58 and a nose portion 60.
  • the second release pawl member 56 extends from the spigot such that it extends beyond the first and second brackets. It will be understood that the release pawl 8 extends in the second plane as the catch claw 6.
  • the release pawl 8 When it is desired to open the bonnet, the release pawl 8 is actuated.
  • the release pawl 8 is conveniently actuated by control means located within a passenger cell of the motor vehicle, but may also be actuated in any other suitable manner.
  • the second release pawl member 56 When actuated, the second release pawl member 56 is urged to in a clockwise rotational movement around the spigot 40 as shown in the drawings by arrow A.
  • the first release pawl member 54 is moved in a clockwise rotational movement around spigot 40, thereby releasing the first lug 51 of the second catch claw member 44 from the release pawl recessed surface 58.
  • the catch claw is now free to rotate in an anti clockwise manner, as shown by arrow B.
  • the release pawl is held against the release pawl biasing means by the outer surface 49 of the second catch claw member 44 abutting the nose portion 60 of the release pawl and is so unable to return to the closed position.
  • the driving surface 50 between the first and second catch claw members pushes the striker pin upwards.
  • This movement of the striker pin raises the curved surface 26 of the second safety hook member against the force of the biasing means.
  • This has the effect of causing the safety hook 4 to rotate clockwise about the first spigot 14 as shown by arrow C, moving the remote end 18 of the first safety hook member 16 clockwise about spigot 14 as shown in Figure 2.
  • This in turn displaces the safety hook release presenter 22 forwards to the left as shown in Figure 2.

Abstract

L'invention concerne un ensemble de fermeture destiné à retenir de façon libérable une gâche (2), lequel ensemble comprend un crochet de sécurité (4) sollicité pour avoir un mouvement rotatif dans une position fermée après être passé dans une position entrouverte à partir d'une position ouverte, un loquet (6) sollicité de manière pivotante pour avoir un mouvement rotatif à partir d'une première position dans laquelle la gâche (2) est empêchée de venir dans une seconde position dans laquelle la gâche (2) est entraînée dans une position prédéterminée, et un cliquet de libération (8) sollicité pour avoir un mouvement de rotation entre une première position dans laquelle le loquet (6) est maintenu dans la première position et une seconde position dans laquelle le loquet (6) est libéré pour passer dans la seconde position, caractérisé en ce que le loquet (6) et le crochet de sécurité (4) sont en aboutement mutuel de manière que, lorsque le loquet (6) est placé dans sa seconde position, le crochet de sécurité (4) soit placé dans sa position entrouverte et la gâche (2) soit maintenue dans une position partiellement retenue par le crochet de sécurité (4).
