Abstract
A device for fastening a first member such as a head rest relative to a second member such as a head rest supporting member in an inclining adjustable manner, including a one-way ratchet and pawl mechanism incorporated between the two relatively rotatable members, wherein the pawl is driven out of engagement with the ratchets when the two relatively rotatable members have been brought to an extreme relative position allowed by one-way sliding engagement of the ratchets and the pawl, and a control member which catches and holds the driven up pawl at the extreme relative rotational position and releases the pawl when the two relatively rotational members have been brought to the other extreme relative rotational position so as to make the pawl again engage the ratchets at the second mentioned relative rotational position.
