Abstract: A motor-vehicle armrest has a base fixed on the vehicle and defining an axis and an armrest part pivotal on the base about the axis and having a first concave surface turned radially inward toward a second convex surface of the base. A wedge-shaped sprag is slidable between the surfaces generally angularly of the axis between a locking position in which the armrest part is arrested relative to the base and a release position in which pivoting of the armrest part with respect to the base is possible. The sprag has a first contact face cooperating with the first surface of the armrest part and a second nonparallel contact face cooperating with the second surface of the base. The sprag is biased into the locking position and can be moved into the release position.

Abstract: The invention relates to an accessory for a motor-vehicle interior, in particular an armrest (10) for vehicle seats, wherein an accessory (11) is pivotal on a base element (19) solid with the vehicle by means of a pivot, wherein the accessory comprises a freewheel (18) with at least one sprag (24) that can be moved between a locking position, in which the accessory (11) is stopped relative to the base element (19), and a release position in which a pivoting movement of the accessory (11) with respect to the base element (19) is possible, wherein at least one sprag (24) with at least two contact faces (25, 26) is provided, whereof a first contact face (25) cooperates with a first counter-surface (22) associated with the accessory (11) and a second contact face (26) cooperates with a second counter-surface (23) associated with the base element (19).
