    • An adjustable armrest for a vehicle seat in which a ratchet mechanism is provided to resist downward movement of the armrest and allow upward movement to adjust the armrest position relative to the seat back. The ratchet mechanism is released upon raising the armrest passed the upper end of its adjustment range enabling the armrest to be lowered to the lower end of its adjustment range wherein the ratchet mechanism again engages to hold the armrest in place. Attachment of the armrest to the seat back is provided by sliding the armrest over a mounting stud extending laterally from the seat back. A wire spring clip attached to the armrest seats in a groove in the stud to hold the armrest axially on the mounting stud. When assembled, the spring clip will be positioned at the interface between the armrest and the seat back enabling a flat tool such as a screw driver to be inserted between the armrest and the seat back to manipulate the clip to remove the armrest.
    • 一种用于车辆座椅的可调式扶手,其中提供棘轮机构以阻止扶手的向下运动,并允许向上运动以相对于座椅靠背调整扶手位置。 棘轮机构在将扶手通过其调节范围的上端升高时释放,使得扶手能够降低到其调节范围的下端,其中棘轮机构再次接合以将扶手保持在适当位置。 通过将扶手滑动到从座椅靠背横向延伸的安装螺柱上,将扶手安装到座椅靠背上。 安装在扶手座上的电线弹簧夹座位于螺柱的凹槽中,以将扶手轴向保持在安装螺柱上。 当组装时,弹簧夹将位于扶手和座椅靠背之间的接口处,使得能够在扶手和座椅靠背之间插入诸如螺丝刀的平面工具来操纵夹子以移除扶手。
