A hole 53 having a constant diameter extends through the top cover 50 and the base plate 51 to the portion of the hole provided in the base plate to form an inner rim 54. The outer peripheral surface of the cylindrical inner rim 54 projects with respect to the release ring 55 having a central opening 56 having a diameter corresponding to the diameter of the hole 53 and the upper cover 50, and both ends change according to the diameter of the hole 53. A rotation axis of rotation of a pair of annular ledges 57 forming the bearing surfaces 58, 59 is defined.

The latch member is a substantially fixed blade 60 extending between opposing ends of the base plate 51, such as a chord to the hole 53. A blade spring 61 having a curved contour is substantially fixed at a midpoint in the longitudinal direction with respect to the base plate. The opposing flared fingers 62, 63 cooperate with the edges of the adjacent blade 60 such that the blade 60 meshes with the holding surfaces 58, 59. In this position, the curved surfaces 64, 65 at the opposing ends of the blade 60 cooperate with the complementary holding surface (not shown) of the top cover 50 to retain the striker pin inside the latch. In position, the recess 67 traverses the hole 53 at a substantially midpoint along the length of the blade 60.

The helical spring 70 surrounds the release ring 55, and the opposite ends of the spring 70 project from the base 57 toward the upper cover 50 and are fixed to the holding receivers 71, 7.
Fixed to 2. The helical spring 70 holds the release ring 55 in a neutral position in which the holding surfaces 58, 59 are spaced apart by the diameter of the hole 53 and are parallel to the side of the base plate 51.

7 is connectable by a cable pull which exits through openings 77, 78 at the end of the cover through complementary grooves 75, 76 in the cover. Usually only one puller is provided. When pulling the cable pull out through the opening 78 to release the latch, the pulling force from the cover 50 will force the inner rim 54 as a shaft against the force of the helical spring 70. It operates to move the release ring 55 at a certain angle around it. The movement of the release ring 55 subsequently pulls the recess 67 from the hole 53 and causes the curved surface 64 of the blade 60 to pivot about the complementary bearing as an axis. 59 is activated. Thus, the blade 60 operates as a lever that pivots about the holding surface 59 as a fulcrum for the force on the blade spring 61. The hood is thus releasable with a striker pin pulled from the latch.

When the puller is released, the spring 63,
The energy stored in 70 is released to return blade 60 and ring 55 to the holding position shown in the drawing. The latch is releasable by using a pull in one of two opposite directions.

To close the hood, the hood is simply moved against the latch using a striker pin. The striker pin moves the blade 60 so that the head of the striker pin generally moves the blade 60 away from both carrying surfaces in the cover 50 until it is held under the blade past the blade leaf. Act on.
