  • a spring anchoring portion 140 bent perpendicularly to the surface of the pawl 14 is provided Likewise. a lower part of the first latch member 13 is bent perpendicularly to the surface of the first latch member 13 thereby to provide a spring anchoring portion 13/1, and a coil spring 21 is stretched between the two spring anchoring portions 140 and 135;.
  • the first latch member 13 is urged to rotate in the counterclockwise direction. while the pawl 14 is thereby urged to rotate in the clockwise direction.
  • the pawl member 14 is further provided with a cam surface l4fon the left side edge of the pawl member at a portion between the second engaging portion 14a and the upper end of the pawl member l4). the cam surface 14f conforming to the locus of the tip of the tooth portion 13- as the first latch member 13 is rotated around the pivotal shaft 16.
  • the base plate 11 is also provided with mounting flanges lle and 11f on the right side and left side ends thereof as shown in FIG. 2.
  • the second latch member 15 is further provided with a cam surface 15d between the hooked portion 15b and the third engaging portion 150.
  • the cam surface 15:! contacts the striker 12 when the latter comes down into the U-shaped recess 11a of the base plate 11, whereby the second latch member 15 is rotated in the counterclockwise direction around its pivotal shaft 17.
  • the hood latch device of the above described structural organization according to the present invention operates as follows.
  • the rotation of the pawl 14 is transmitted through the catch portion 14d of the pawl 14 to the right side edge (or shoulder) of the second latch member 15, thereby rotating the second latch member 15 around the pivotal shaft 17 in the counterclockwise direction.
  • the catch portion 14d of the pawl 14 is separated from the right side edge (or shoulder) of the second latch member 15, and the torque applied to the second latch member 15 through the catch portion 14d of the pawl 14 is removed.
  • the above described clockwise rotation of the pawl 14 tends to rotate the second latch member 15 clockwise as a result of the action of the torsional spring 19, such a rotation is prevented because of the engagement of the cam surface 15d of the second latch member 15 with the lower end of the striker l2, and the second latch member 15 is thus held in the position shown in FIG. 3, wherein the hood of the vehicle is completely closed.
  • a lever (not shown) or a button (not shown; is operated at the vehicle driver's seat, thereby pulling the wire 20 to the right as viewed in FIG. 3.
  • the end piece 20a of the wire 20 is displaced rightward along the arcuate slot 14)), thereby rotating the pawl 14 to a position as indicated by the chain line in FIG. 3.
  • the engagement be tween the tooth portion 130 and the second engaging portion 14a of the pawl 14 is broken, and the striker 12 is thrown upward by the forces of the springs 18 and 21.
  • the catch portion 14d of the pawl 14 is at this time urging the shoulder of the second latch member to turn in the counterclockwise direction when the wire is pulled rightward, and the second latch member 15 is thereby held in the position indicated by the chain line in FIG. 3.
  • the first latch member 13 is rotated counterclockwise to a position as shown in FIG. 4 or FIG. 1, and the third engaging portion 150 of the second latch member 15 thereby engages the catch portion 130 of the first latch member 13 even after the wire 20 has been released.
  • the cam surface 14f of the pawl 14 conforms to the locus of the tip of the tooth portion 13(- of the first latch member 13.
  • the catch portion 14d of the pawl 14 holds the second latch member 15 at the position indicated in FIG. 3 by the chain line as long as the tooth portion 130 is contacting the cam surface 141' of the pawl 14.
  • the third engaging portion 15- of the second latch member 15 engages the second catch portion 130 of the first latch member 13, whereby the hooked portion 15b of the second latch member 15 is held at a position engageable with the striker l2, and further opening of the hood beyond this state is thereby prevented.
  • the first latch member 13 When it is desired to open the hood from the state indicated in FIG. 4 by disengaging the second latch member 15 from the striker 12, the first latch member 13 is rotated around the shaft 16 against the tension of only the spring 21 by manually depressing the lever portion 13f of the first latch member 13 because the free end of the spring 18 is sustained by an end of the arcuate slot 110, and the hole 13;; of the first latch member 13 is of an elongated configuration.
  • the second catch portion 130 of the first latch member 13 is thus disengaged from the third engaging portion 15c of the second latch member 15, and the second latch member 15 is rotated clockwise to the position shown in FIG. 1 by the force of the spring 19.
  • the second latch member 15 is thus disengaged from the striker l2, and the hood is thereby opened.
  • the hood latch ing device is so organized that when the pawl is disengaged from the first latch member, the movement of the pawl forces the second latch member to move into a position where the hooked portion of the second latch member is firmly held against any accidental release of the striker even in the cases where the pawl is disengaged from the first latch member by shock or vibration to which the vehicle body is subjected, whereby the possibility of the hereinbefore described loss of visibility due to full opening of the hood by wind pressure can be substantially eliminated.
  • a hood latching device for an automotive vehicle having an openable hood comrising: a striker secured to the hood; a base plate secured to the vehicle; a first latch member pivotally mounted on the base plate so as to be rotatable between an unlatching position and a latching position and having a first engaging portion engageable with the striker and a catch portion; a second latch member pivotally mounted on the base plate so as to be rotatable between a striker-arresting position and a non-arresting position and having a hook portion also engageable with the striker to arrest the same in said arresting position and a second engaging portion; a pawl member pivotally mounted on the base plate and having a third engaging portion engageable with the first engaging portion of the first latch member in said latching position of the same for assuring latching engagement between the striker and the first engaging portion of the first latch member; and catch means provided on the pawl member and being operative to abut against said second latch member to displace the same to said arrest
  • a hood latching device as set forth in claim 2 wherein said cam surface means provided on the pawl member is so shaped that it conforms to the locus of the tip of said first engaging portion of said first latch member when the latter member is rotated between its latching and unlatching positions.
