VEHICLE ASSEMBLY

A trim panel is attached to an inboard surface of a door structure and includes an armrest and an armrest retaining structure. A portion of the trim panel defines an armrest opening with the armrest installed through the armrest opening. The armrest has an outboard portion with an outer peripheral flange that overlays a portion of an outboard surface of the trim panel. The armrest retaining structure is attached to the outboard surface of the trim panel at location adjacent to the armrest opening. The armrest retaining structure retains the armrest in position relative to the trim panel. The armrest retaining structure is further configured to release the armrest for movement in an outboard direction upon application of a predetermined first level of force to the armrest.
