The ditch molding clip can include a single piece body. The single piece body can include (1) an outer frame surrounding an interior opening, (2) a clip-to-molding retention coupling including a plurality of resilient arm members extending from the outer frame and designed to engage and retain a corresponding edge of the molding, (3) a clip-to-weld-stud retention coupling positioned within the interior opening and including an aperture designed to receive and retain the weld stud, and (4) an extensible member extending between the outer frame and the clip-to-molding retention coupling. A longitudinal length of the extensible member can be designed to lengthen to allow the clip-to-weld stud retention coupling to move within the interior opening to accommodate for variations in the positioning of the weld stud relative to the ditch. The extensible member can have a corrugated configuration.

A component for a vehicle interior configured to deform under a load is disclosed. An armrest for a vehicle interior configured to deform under a load is disclosed. A method for forming the armrest is disclosed. The armrest may comprise a substrate and base formed on the substrate. The base may comprise a core and a surface (or skin). The core may comprise a material configured to deform under a load (e.g. impact). The method for forming the armrest may comprise the steps of: (a) placing the substrate in a mold and (b) forming the base on the substrate. A coating may be provided in the mold. The substrate may be formed from a plastic material such as a thermoplastic material to provide a structure. The base of the armrest may be formed from a plastic material such as a polyurethane foam material to form the core with integral surface/skin.

A single piece retention clip for attaching a foam part to a substrate is disclosed. The retention clip includes a pair of spaced apart and opposed curvilinear retention clip arms, a planar foam part retaining member, and a bridge having first and second ends. The first bridge end extends from the planar foam part retaining member. The clip arms are flexibly attached to the second bridge end. The insulation part is captured between the planar foam part retaining member and the clip arms, prior to attachment of the clip to the substrate. An operator-usable handle to facilitate clip insertion and removal relative to the substrate may be formed on the foam part retaining member. Each clip arm includes a body having wide and narrow parts. The wide part of each of clip arm is attached to the bridge. A hook is formed at the narrow part of each arm.
