Height adjuster carriage for loop-around fitting, has forced coupling inducing tight-conditioned movement of locking bolt downwards to coupling, such that actuator loads bolt in direction of its engagement in locking opening

摘要

The carriage (12) has a locking bolt (22), an actuator (24) and a forced coupling that is provided between the bolt and the actuator to induce a tight-conditioned movement of the bolt downwards to the coupling, such that the actuator loads the bolt in a direction of its engagement in a locking opening of a height adjuster. The actuator is adjustably attached at the carriage. The actuator has a guideway (28), and the locking bolt has a pin (26) that is engaged in the guideway.
