Abstract: A wind bulkhead device for motor vehicles provided with an open bodywork is described. The wind bulkhead can be pivoted between an erected bulkhead position and a rear folded-down position, and covers the space between the head restraints of adjacent seats, in particular adjacent rear seats. The wind bulkhead is stabilized via the head restraints in their extended position by an of elastic knock-over resistance element and, when the head restraints are lowered, can be automatically pivoted from its bulkhead position, in which it is preferably erected manually, into its folded-down position.
