    • A position adjusting apparatus for a back of a stroller includes an engaging rod, a controlling slide member, and a positioning block. The positioning block is fixedly connected to at least one handle support rod of the stroller, and has several engaging protrusions each having a positioning gap formed adjacent thereto. The engaging rod is movably received in a lower tube portion of a frame of the back, and is connected to the controlling slide member movable along an outer side of the lower tube portion. A pivotal rod is connected to the positioning block and the lower tube portion, and passes through an elongated hole of the engaging rod to pivot the back frame on the positioning block. The engaging rod is biased by a spring to extend outward from the lower tube portion such that an engaging lower part thereof engages a selected one of the engaging protrusions to fix the back frame in position. The controlling slide member may be pushed to withdraw the engaging rod into the lower tube portion so as to disengage its engaging lower part from the engaging protrusion of the positioning block, freeing the back frame for position adjustment.
    • 用于婴儿车背部的位置调节装置包括接合杆,控制滑动构件和定位块。 定位块固定地连接到婴儿车的至少一个手柄支撑杆上,并且具有几个接合突起,每个接合突起具有与其相邻形成的定位间隙。 接合杆可移动地容纳在后部的框架的下管部分中,并且连接到可沿着下管部分的外侧移动的控制滑动构件。 枢转杆连接到定位块和下管部分,并且穿过接合杆的细长孔以将后框架枢转在定位块上。 接合杆被弹簧偏压以从下管部分向外延伸,使得其接合下部接合所选择的一个接合突起以将后框架固定就位。 可以推动控制滑动构件将接合杆缩回到下管部分中,以使其接合下部与定位块的接合突起脱离,释放用于位置调节的后框架。
