ABSTRACT:
The latch comprises a pivotal fork member adapted to receive a keeper (4), an intermediate catch (6) adapted to cooperate with the fork member (1) for maintaining the latter in the latching position, and a main catch (14) cooperative with the catch (6) for maintaining the latter in its position for locking the fork member (1), these elements being biased by return springs. The main catch (14) is provided with an arm (19) which, at the beginning of the latch opening sequence, and if the latch is in a bad state of maintenance, comes to bear against the arm (8) of the intermediate catch (6) and urges the latter to pivot in the direction for releasing the fork member (1). The presence of the arm (19) on the main catch (14) guarantees the opening of the latch without difficulty throughout the life of the vehicle, notwithstanding the hindrance that the progressive disappearance of the lubrication and the accumulation of dust might create in respect of this opening.
