<p>The device (4) has articulated arms (10) fixed at its ends over a joint (12) and around pivotable a hinge axis (G) of the joint against a spring force (Pf) in a folded position. A mechanical coupling (22) acts between the two articulated arms and is provided for synchronization of the pivoting movement of the arms. The articulated arms have inner- and outer arms (14, 16) pivotable to each other. The coupling has two rotary members i.e. gear wheels, connected with the respective articulated arms in a torque-proof manner.</p> |
