    摘要： A window balance assembly for installation in a window assembly can include a balance portion that is connected to a carrier that may have a first and second side. The balance portion may be arranged to be drawn out of the carrier on the first or second sides of the carrier. The balance portion may be a spring member or element. As the spring element is drawn out of the carrier, contact made between the spring element and the carrier may generate a friction that results in undesired chatter of the spring element and/or audible noise from the carrier. This friction may be reduced by controlling the contact made between the spring element and the carrier. Further, a reduction of friction between the spring element and the carrier may result in a reduction in spring chatter and a reduction in audible noise from the carrier.

    摘要翻译： 用于安装在窗户组件中的窗户平衡组件可以包括连接到可以具有第一和第二侧的托架的平衡部分。 平衡部分可以布置成在承载件的第一或第二侧被拉出承载件。 平衡部分可以是弹簧构件或元件。 当弹簧元件被拉出载体时，在弹簧元件和载体之间形成的接触会产生摩擦，导致弹簧元件的不期望的颤动和/或来自载体的可听见的噪音。 通过控制弹簧元件和载体之间的接触可以减小该摩擦。 此外，弹簧元件和载体之间的摩擦力的降低可能导致弹簧颤振的减小和来自载体的可听到的噪声的降低。

    摘要： A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier. The mounting bracket may include a first mounting surface disposed at a non-perpendicular angle relative to an exterior surface of carrier when the window balance assembly is in an uninstalled configuration. The first mounting surface may be substantially parallel to the exterior surface of the carrier when the window balance assembly is in an installed configuration and the mounting bracket is disengaged from the carrier.

    摘要： A counterbalance system for a window assembly having a window sash that moves in a guide track. The counterbalance system has a first stop mounted in the guide track. A spring housing is placed in the guide track above the first stop. The spring housing holds the counterbalance spring that provides the counterbalance force. The spring housing is free to move along the guide track above the first stop. The spring housing is incapable of passing the first stop and traveling below the first stop. A brake shoe is positioned in the guide track. The counterbalance spring has a free end that extends from the spring housing to the brake shoe. The brake shoe is capable of moving in the guide track past the first stop. In this manner, the brake shoe can be raised above the first stop.
