US Patent 7637553 Head restraint for a convertible motor vehicle

A motor vehicle is disclosed having one or more seat assemblies each of which has an automatically stowable head restraint associated with it. Each head restraint is pivotally supported by a stowable rear roof panel and is biased into a stowed position in which it lies adjacent to the rear roof panel by a spring. A latch mechanism is used to hold the head restraint in a lowered position in which it depends downwardly from the roof panel for use by an occupant of the motor vehicle. The latch mechanism is automatically released by the process of stowing the rear roof panel or a front roof panel.
