Hinge device for the articulated attachment of a hood to a vehicle chassis

摘要

The present invention relates to a hinge device (1) for the articulated attachment of a hood to a vehicle chassis, the device comprising a lower bar (3) and an upper bar (5) attached to one another in an articulated manner; a retaining mechanism (8) which, in a retaining position (R), maintains the angle ± formed by the lower and upper bars (3,5) and fastens the assembly formed by said bars to a support body (2) such that the device adopts a compact shape; and an actuator (9) capable of moving the retaining mechanism (8) to a release position (L), disabling the function of the mentioned retaining mechanism (8), the device (1) being prepared for adopting at least two different collapsed shapes (A and B) without the actuator (9) moving the retaining mechanism (8) 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 (1), caused by hitting a pedestrian, for example.
