Problems solved by technology

[0012] In fact, in the event of a crash of the repairable frontal type, defined as a 40% coverage, facing a rigid wall with an angle of 10°, at 16 km / h, the bonnet's Lateral displacement (along the vehicle's transverse axis Y) will cause deformation of the wing, which results in additional maintenance costs associated with replacing or repairing the wing

Embodiment Construction

[0034] refer to figure 1 , the area D bounded by the dot-dash line locates the possible placement area on the vehicle 1 of the hinge of the openable part 2, which is advantageously used to protect such as the front wing 3 in the event of a collision between the vehicle and an obstacle. Other parts around the body.

[0035] The openable part 2 is the closure cover of the engine compartment at the front of the vehicle, which is a body part extending transversely through the left and right front wings. exist figure 1 Only the right front wing 3 is shown in , which is known to exist by symmetry with respect to a median plane extending parallel to the vehicle longitudinal axis x.

[0036]In the following, the terms "left", "right", "front" and "rear" are understood according to the normal movement of the vehicle. This is non-limitative and for the sake of clarity in the following only one side of the vehicle is described, it being understood that by virtue of symmetry the same t...

Abstract

The invention relates to a hinge (4) of a leaf such as a bonnet for closing an engine compartment on a motor vehicle body, said hinge (4) comprising a stationary part (5) and a movable part (6), the movable part (6) being mounted such that it can be rotated about a pivoting axis (A) of the stationary part (5), between an opening position and a closing position of the hinge (4), the movable part (6) having a retaining element (7) that protrudes from said movable part (6) towards the stationary part (5) in the pivoting plane of said hinge (4). According to the invention, the stationary part (5)comprises a complementary retaining element (8) along which the retaining element (6) of the movable part extends in the closed position of the hinge (4).

Description

technical field [0001] The invention relates to a hinge for an openable part of a motor vehicle comprising a body structure on which a body part such as an openable Assembled together, the openable part is hinged on the vehicle body structure through the at least one hinge. Background technique [0002] Articulation hinges are known comprising a fixed part defining an axis of rotation about which a movable joint is adapted to pivot in order to move an openable part such as a hood for closing an engine compartment between an open position and a closed position . [0003] The articulation hinges of the bonnet closing the nacelle are usually made of a material which has little resistance to deformation, which allows easy molding and has the advantage of being cheaper. [0004] Such hinges are insufficient to adequately maintain the bonnet, which is hingedly connected to the body structure of the vehicle, in the event of a vehicle collision with an obstacle, which leads to veh...
