Antiblocking vehicle door edge protector
An assembly of a vehicle door ( 3 ) and of a panel ( 1 ) surrounding the door in which an edge protector ( 4 ) extends along a skin ( 3 a ) of the vehicle door facing the skin ( 1 a ) of the panel and has a portion disposed between the skins ( 1 a, 3 a ) following when in a nominal position the geometric alignment of their exterior faces. This edge protector ( 4 ) has in a median portion ( 4 b ) a profile that is adapted to evolve and is made of an elastic material so that it has sufficient flexibility in a direction parallel to the distance between the skins ( 1 a, 3 a ) and a transverse stiffness in the internal-external direction and its contact with the skin ( 1 a ) of the panel does not block opening of the door or damage the skins ( 1 a, 3 a ).
1 . A door ( 3 ), panel ( 1 ) protection assembly comprising:
a vehicle door ( 3 ) and a panel ( 1 ) surrounding the door ( 3 ), the door ( 3 ) having a skin ( 3 a ) with external faces and the panel ( 1 ) having a skin ( 1 a ) including external faces, the external faces of the door and the external faces of the panel have a same profile that are aligned when the door ( 3 ) is in a closed position, the door ( 3 ) having a centering abutment ( 3 d ) and the panel ( 1 ) having a centering abutment ( 1 d ), the abutments face each other with a predefined clearance, the door ( 3 ) having an edge protector ( 4 ), the edge protector:
extends along a perimeter of the door skin ( 3 a ) facing the panel skin ( 1 a ) separating an interior (INT) and an exterior (EXT) of the vehicle,
includes an anti jamming portion disposed between the skins ( 1 a , 3 a ) in a geometrical alignment position of the respective exterior faces, and
is made of an elastic material with a profile adapted to evolve in the anti-jamming portion having sufficient flexibility in a direction parallel to the clearance between the skins ( 1 a , 3 a ),
the edge protector ( 4 ) has a clearance ( 5 c ) between an edge face of the edge protector and an edge face of the skin of the panel ( 1 a ) less than the clearance ( 5 b ) between the centering abutments ( 1 d , 3 d ),
wherein in the event of a minor accident, the skins ( 1 a , 3 a ) remain at a distance from each other greater than a minimum distance when the centering abutments ( 1 d , 3 d ) come into contact while having a transverse rigidity in the internal-external direction limiting deflection of this edge protector ( 4 ) to less than or equal to 2 mm under a local external aerodynamic pressure of 1 psi (69 mBar),
wherein the clearance ( 5 c ) is ≤75% of the clearance ( 5 b ) between the centering abutments ( 1 d , 3 d ).
2 . The door ( 3 ), panel ( 1 ) protection assembly as claimed in claim 1 , wherein a gap is preserved between the edge protector ( 4 ) and the facing skin of the panel ( 1 a ) while externally assuring the geometric continuity between the external faces ( 10 a , 30 a ) of the skins ( 1 a , 3 a ) so that the edge protector ( 4 ) is referred to as open under nominal door closure conditions.
3 . The door ( 3 ), panel ( 1 ) protection assembly as claimed in claim 1 , wherein the edge protector ( 4 ) is installed on an entire perimeter of the door ( 3 ), on a portion of or on a plurality of portions of the perimeter.
4 . The door ( 3 ), panel ( 1 ) protection assembly as claimed in claim 1 , wherein the edge protector ( 4 ) is made of a hyper-elastic material chosen from rubber or silicone.
5 . The door ( 3 ), panel ( 1 ) protection assembly as claimed in claim 1 , wherein the edge protector ( 4 ) includes on one edge a flat ( 4 a ) for fixing it to an internal face of the skin of the door ( 3 a ) inside the vehicle.
6 . The door ( 3 ), panel ( 1 ) protection assembly as claimed in claim 5 , wherein a door closure seal ( 1 f ) is mounted on the fixing flat ( 4 a ) when the door ( 3 ) is closed.
7 . The door ( 3 ), panel ( 1 ) protection assembly as claimed in claim 5 , wherein the edge protector ( 4 ) includes a lip ( 4 c ) formed on another edge that extends transversely inward.
8 . The door ( 3 ), panel ( 1 ) protection assembly as claimed in claim 1 , wherein the edge protector ( 4 ) includes an exterior antifriction coating.
