An apparatus (10) includes a molded portion (60) associated with an inflatable vehicle occupant protection device (14). The molded portion (60) is molded as a single piece of plastic material. The molded portion includes a base portion (64) and a reinforcing portion (100). The base portion has a first thickness measured between a first class A surface (42) and an opposite second surface (80). The reinforcing portion (100) includes a main wall portion (126) spaced from the second surface and at least one side wall (110, 112, 114, 116) extending from the main wall portion, merging with the second surface, and having a second thickness about equal to the first thickness. The main wall portion (126), base portion (64), and at least one side wall (110, 112, 114, 116) define a chamber (170) in the molded portion.
