Abstract
Abstract A method for making an armrest or the like used in vehicles where the armrest is affixed to the vehicle door and also serves as a grab-handle to enable the passenger to pull the door closed. The method is an injection molded vinyl process that utilizes a two-piece insert in the main body of the armrest which allows foam to be introduced into the upper portion and inboard side where the user's arm rest. This method produces a more comfortable armrest that also is more visually pleasing and one that can be produced at a lower cost than known armrests of this type.
