ABSTRACT:
A pivoting mechanism having two lockable end positions, and comprising a stationary basic body having two first stop surfaces each defining an end position in cooperation each with a different one of first counter stop surfaces on a pivotable basic body drivable by means of a pivot shaft journalled in the stationary basic body. One of the basic bodies is further provided with two second stop surfaces directed oppositely to the first stop surfaces and each arranged, for locking one of the end positions, to cooperate with one of two second counter stop surfaces on a pawl member mounted for movement on the other basic body. The movement of the pawl member is controlled by a cam on a control body secured to the pivot shaft for rotation relative to the pivotable basic body.
