Abstract:
1. A backrest for a vehicle comprising: a lean-on surface having a subsection of the backrest defining an interfering structure movable between a blocked position and an unblocked position; a head restraint which can be adjusted to a higher position, the head restraint comprising: a head part and a support slidably received in the backrest, the head part being transferable from a use region, which is delimited by an upper use position and a lower use position, into a lower not-in-use position, wherein the support simultaneously moves the interfering structure forward relative to the lean-on surface upon transfer of the head part into the lower not-in-use position; and a lever arrangement between the interfering structure and the support configured to project forward relative to the lean-on surface of the backrest to force the interfering structure forward to the blocked position when the head part moves from the lower use position to the lower not-in-use position and simultaneously moves the support vertically within the backrest to act dynamically on the lever arrangement, wherein the interfering structure maintains the blocked position when the backrest is in a folded position proximate a seat cushion.
