Abstract:
A seal providing a soundproofing effect for a motor vehicle opening leaf (19), said seal being fitted to said opening leaf or a surround of an opening in a vehicle bodywork operatively associated with said opening leaf, said seal comprising a tubular section piece (15) of an elastically deformable material which is securable to the opening leaf or to the surround while projecting outwardly therefrom so as to be compressed and deformed between the surround and the opening leaf (19) when the latter is in the closed position, at least one orifice (16) being formed in the side wall of the tubular section piece (15), a first flexible lip (17) projecting inwardly from the interior wall of said tubular section piece (15), at least one second flexible lip (18) projecting toward the inside of the tubular section piece in a direction towards the first lip (17) from an opposite portion of the interior wall of the tubular section piece, the dimensions of the first and second lips (17, 18) being such that, when the tubular section piece (15) is in a compressed position upon closing of said opening leaf (19), said lips (17,18) are in a substantially overlapping mutual surface contact or in contact with the opposite wall of the tubular section piece to form a sealed chamber having an outer surface thereof compressively contacted by said closed opening leaf (19) and producing a barrier in the path of any sound waves propagating towards a cabin of the motor vehicle.
