Abstract: In an arrangement for releasably mounting pivotable arm rests of seats, especially center arm rests of motor vehicle rear seats, pivot pins which engage on both sides in a support placed on the back rest of the seat are attached to the arm rest.The support is split so that it has a metal support part with two bearing arms, placed on either side of the arm rest, which have slot-like bearing recesses open at one side and form a first bearing part. The slot-like bearing recesses can each be closed by plastic caps which can be fitted onto the bearing arms. The plastic caps form a second bearing part and simultaneously serve as covers for the bearing points.

Abstract: A mounting or locking device, the latter especially for use with foldable, lockable seat backs for motor vehicle rear seat assemblies, includes a mounting or locking housing for accommodating a bolt or other latching element to be retained therein, an arresting element which is mounted for movement on the mounting or locking housing, and which is actuable against a spring force in the direction of the "release position", and an actuating element acting on the arresting element. The mounting or locking housing and the arresting element are combined into one integral, unitary structure which is made of plastics, with the arresting element being formed onto the mounting or locking housing through a bracket. The bracket also serves as a pivot bearing and a resilient element for the arresting elment.A mounting or locking assembly of this type is characterized by the sparsity of parts required for its manufacture. It is simple in design, economical to manufacture and easy to assemble.
