The invention relates to the technical field of seats, and discloses a stepless armrest assembly which comprises a bottom plate, a shell installed on the bottom plate and a center shaft, a one-way assembly, a shifting piece and a rotating ring are sequentially installed in the shell, the one-way assembly comprises a one-way rotating block, at least two protruding parts are fixed to the side wall of the one-way rotating block, and an elastic piece and a friction column are installed between every two adjacent protruding parts. A notch is formed in the shifting piece, and a stop block which penetrates through the notch and then is inserted between every two adjacent protruding parts is fixed to the rotating ring. The stepless handrail assembly has the following advantages and effects that the one-way assembly is provided with the one-way rotating block, the friction column, the elastic piece and the stop block, when the friction column abuts against the inner wall of the shell through adjustment of the position of the stop block, the one-way assembly and the center shaft can rotate forwards at the moment, and the guide slope guides the friction column to continuously get close to theinner wall of the shell when a reverse rotation trend exists; the one-way assembly and the central shaft are limited to turn over, stepless adjustment of the position of the handrail connected with the central shaft can be achieved, and adjustment noise is low.

    本发明涉及座椅技术领域,公开了一种无级扶手组件,包括底板、安装在底板上的外壳、中心轴,外壳内依次安装有单向组件、拨片、转环,单向组件包括单向转块,单向转块侧壁固定有至少两个凸部,相邻两个凸部之间安装有弹性件、摩擦柱,拨片开设有缺口,转环固定有穿过缺口后插到相邻两个凸部之间的挡块。本发明具有以下优点和效果:单向组件通过设置单向转块、摩擦柱、弹性件、挡块,通过挡块位置的调整使摩擦柱抵接在外壳内壁时,此时单向组件及中心轴能正向转动,有反向转动趋势时导向斜面导向摩擦柱不断靠近外壳内壁,限定单向组件及中心轴翻转,能实现与中心轴相连的扶手位置的无级调节,调节噪音小。
