Coextruded root ditch molding with hard and soft components including associated fastener system
View Patent ↗A coextruded molding for mounting within a vehicle roof ditch having an elongated trim defining component constructed of a first material and a structurally supporting component constructed of a second harder material coextruded along a surface of the first material. The structural supporting component includes a main body terminating at inwardly angled ends so as to define an extending track. A plurality of fasteners are seated within the track for mounting the molding to the vehicle roof ditch.
1. A coextruded molding assembly for mounting within a vehicle roof ditch, said molding assembly comprising:
an elongated and flexible trim piece exhibiting a generally rectangular shaped profile and having an interconnected and angled lower lip;
a structurally supporting harder material coextruded with an inside surface of said flexible trim material, said structurally supporting material including inwardly angled ends in end profile so as to define an extending track;
additional softer plastic components coextruded along each of an inside surface as well as opposing and inwardly projecting edges of said structurally supporting harder material;
said trim piece further having an inwardly curled upper edge and a spaced and inner protuberance defining therebetween a support surface against which is coextruded said structurally supporting material;
a plurality of fasteners each including a main body dimensioned to seat within the track and adapted for mounting the molding to the vehicle roof ditch; and
a pair of spaced apart recesses defined within an underside surface of said main body associated with each of said fasteners, said recesses aligning and seating said inwardly projecting coextruded softer components in combination with said softer plastic component coextruded along said inside surface of said structurally supporting material in contact with an outer surface of said fastener main body in order to provide for misalignment deflection during installation of said fasteners within the track.
2. The molding assembly as described in claim 1 , further comprising a film material applied over exposed surfaces associated with said trim piece.
3. The molding assembly as described in claim 1 , further comprising a sealing cap for closing off each of opposite ends of an inner track profile established by the structurally supporting harder material.
4. The molding assembly as described in claim 1 , said softer plastic component coextruded along said inside surface of said structurally supporting harder material further comprising an elongate rectangular strip material exhibiting at least one projecting location.
