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 window balance assembly comprising an improved locking carrier mechanism is disclosed. The locking mechanism is actuated when the window sash is tilted. Cam surfaces on the receiver of the mechanism engage cam followers in the clamshell-type housing of the carrier forcing them apart outwardly to lock the carrier in the jamb channel of a window assembly and prevent movement of the carrier in the channel. The receiver incorporates two cams that engage two cam follower surfaces in the housing to improve the distribution of the locking forces of the carrier in the jamb channel. A dual-locking carrier expands in both the axial and lateral directions to contact both front and back surfaces and opposing side surfaces of the jamb channel.
摘要翻译：公开了一种包括改进的锁定载体机构的窗户平衡组件。当窗扇倾斜时，锁定机构被致动。机构的接收器上的凸轮表面接合载体的蛤壳型壳体中的凸轮从动件，使其向外分开，以将载体锁定在窗组件的侧板通道中，并防止载体在通道中的移动。接收器包括两个凸轮，其接合外壳中的两个凸轮从动表面，以改善载体在侧声通道中的锁定力的分布。双锁定载体在轴向和横向方向上都膨胀以接触前侧和后表面以及侧壁通道的相对侧表面。

摘要： The static air dam includes at least one mounting feature, which is preferably at least one hole or slot to allow a fastener, such as a screw, bolt, rivet, weld, or other similar attachment devices, to secure the air dam to a wall of a jamb channel. Air passage through the jamb channel is prohibited or at least substantially inhibited by the static air dam that is designed to approximate the size and dimensions of the cross section of the jamb channel. At least one side of the air dam includes a tab or similar structure for securing the free end of the curl spring of a curl spring balance. The air dam includes integrally formed reinforcing elements that either abut or are adjacent to the side walls of the jamb channel. The air dam preferably includes a pair of flexible projections for engaging ears on the curl spring carrier.
