Abstract
The invention relates to a catch device of the type comprising a main casing that houses a hinge hook and a locking lever having one branch carrying a thrust wheel that co-operates with the hook and having its other branch connected by means of a linkage to the outlet from a driving motor and gear box assembly. According to the invention, the linkage (112) includes an oblong slot (122) for enabling the locking lever (106) to pivot in the event of the outlet shaft (113) of the motor and gear box assembly being jammed, and, in addition, an independent trigger (130) is associated with the locking lever (106) so that when triggered in an emergency it causes said lever to pivot far enough to disengage thrust wheel (109) from the associated camming surface (110.1) of the hinged hook (102), thereby releasing it.
