ABSTRACT:
An arm-rest for a vehicle seat comprises an arm-rest carrier confined to substantially translatory vertical motion and an arm-rest member pivoted to the arm-rest carrier to tilt between a normal horizontal orientation and an out-of-the-way vertical orientation. A pawl and ratchet mechanism defines several positions of heightwise adjustment of the arm-rest carrier, at each of which it is held against descent, but is can be readily raised from a lower to an upper limit of its vertical motion. At said upper limit a pawl latch captivates the pawl, holding it away from the ratchet to permit descent of the arm-rest carrier. At said lower limit the pawl latch is disengaged from the pawl, which re-engages the ratchet. A locking element movable on the arm-rest carrier is biased to a locking position in which it engages the arm-rest member to hold the same in its horizontal orientation; but in a raised releasing position of the arm-rest carrier the locking element is disengaged from the arm-rest member to allow it to be tilted to its vertical orientation, from which it can be tilted back to horizontal in any position of the arm-rest carrier.
