A quick acting belt tensioning mechanism for securing a child safety seat into a vehicle has a tensioning member having a hook-like engagement structure rotatably mounted on the safety seat adjacent a belt path for a vehicle seat belt. The seat strap is engaged in the engagement structure and the tensioning member is rotated by movement of the lever, the seat strap being tensioned by wrapping the tensioning member with the seat strap. A lever is slidably disposed on the tensioning member to close the opening of the hook structure and prevent disengagement of the seat strap therefrom, and to prevent rotation of the tensioning member to the tensioned position unless the lever is properly positioned. A latch mechanism is provided to restrain the tensioning member and the lever in the tensioned and closed positions. The seat shell and rod may include structures to further limit tensioning of the seat belt unless the rod is properly positioned.
一种用于使儿童安全座椅固定到车辆中的快速作用的带张紧机构,其具有张紧部件,该张紧部件具有钩状接合结构,该钩状接合结构可旋转地安装在安全座椅上与用于车辆座椅带的带路径邻近。使座椅带接合于接合结构中并由杆的移动使张紧部件旋转,通过使座椅带包绕张紧部件来张紧座椅带。杆可滑动地设置在张紧部件上以闭合钩状结构的开口并防止座椅带从其脱离,且阻止张紧部件旋转到张紧位置,除非杆适当地定位。闩锁机构提供成使张紧部件和杆约束在张紧和闭合位置中。座椅壳和杆可包括结构来进一步限制座椅带的张紧,除非杆适当地定位。
