  • Patent number: 4253537
    Abstract: An instrument panel cover is hingedly supported from opposite panel housing side walls by means of an unitary hinge rod having axially aligned out-turned ends respectively received in blind holes provided in the opposite side walls. The hinge rod is located and configured such as to be substantially hidden when the cover occupies an operative position blocking access to an instrument panel section and such as to guide the cover between its operative position and a stored position against a bottom housing wall extending orthogonally to the panel section at a lower edge of the latter. The cover is respectively releasably retained in its operative and stored positions by means of a key operated cam lock carried by the panel and having a lip engageable with an angled end of a locking rod fixed to the panel section, and by means of a clip provided with a resiliently expandable perforation for receiving the end of ball stud fixed to the lower housing wall.
