Abstract: The present invention relates to a hinge device for the articulated attachment of a hood to a vehicle chassis, the device comprising a lower bar and an upper bar attached to one another in an articulated manner; a retaining mechanism which, in a retaining position (R), maintains the angle ? formed by the lower and upper bars and fastens the assembly formed by said bars to a support body such that the device adopts a compact shape; and an actuator capable of moving the retaining mechanism to a release position (L), disabling the function of the mentioned retaining mechanism, the device being prepared for adopting at least two different collapsed shapes (A and B) without the actuator moving the retaining mechanism to its release position (L) depending on the location of the resultant of a vertical downward force (F) transmitted to the upper bar of the device, caused by hitting a pedestrian, for example.

Abstract: A door retaining device having a housing and a retaining rod which traverses it, the device including a brake housed in the housing having a brake body stressed by a corresponding compression spring towards the retaining rod. The housing is formed by several parts assembled to one another, including a guide body molded in plastic for guiding the rod, provided with a through hole which is traversed by the rod and with at least one side hole in communication with the through hole; and a receptacle, detachably plugged to the side hole of the guide body, which houses and guides the movement of the brake body towards the retaining rod through the side hole, and in which the compression spring is supported to exert its thrusting action on the brake body.
