Abstract:
A mechanical neck rest retraction device with a memory function comprising:a movably supported locking member (26) which is designed to yieldingly be brought into engagement with one of several stop notches (30) of at least one neck rest rod (16); a bridge member (32) which is designed to be connected to the ends of the two neck rest rods (16, 18) and in which a detent member (68) biased by a first spring (70) is movably supported; an elongate actuator (38) adapted to be moved in a parallel direction with both axis of the neck rest rods (16, 18) downwardly against a second spring which biases the actuator upwardly a series of detent recesses on the elongate actuator (38) for the detent member (68), which extends in a longitudinal direction of the actuator (38) and has a spacing which corresponds to a spacing of the stop notches (30), the detent member (68) being located between two adjoining detent recesses (44) when the locking member (26) is in engagement with one of the stop notches (30); and a stationary guide (48) which interacts with the actuator (38) such that when the actuator (38) is in an upper position, the detent member (68) is out of engagement with the actuator (38), such that the actuator (38) is moved towards the detent member (68) from a given displacement path, which causes it to engage the next following upper detent recess (44) and an unlocking member (82) connected to the actuator (38), which actuates said locking member (26) for the release of the neck rest rod (16) when the actuator (38) is moved downwardly.
