    • The apparatus stabilizes loads beneath helicopters to prevent undesirable load movement while allowing in-flight optimization of the load's center of gravity to reduce drag and increase banking capability and top speed. An anchoring bracket secures the apparatus to the helicopter. The apparatus comprises an upper section that controls load pitch and lateral movement and a lower section that controls load height during unloading. A pitch regulator comprises a c-shaped yoke with upper and lower collars penetrated by a hollow shaft and elevator. A lateral movement regulator comprises a coupling and a y-shaped chassis. The coupling comprises a central sleeve captivated between the upper and lower collars and a motor permitting selective rotation about the elevator. The chassis secures to the coupling via a ball and socket and a middle suspension system captivated between coupling and suspension plates. Spaced apart terminal chassis arms support the load via a bearing wing. A winch spools a cable with an load stop resting on a foot. The foot front is pivotally secured to the pitch regulator while the back is pivotally secured to the wing. The wing and the elevator control load pitch. As the elevator retracts or extends, the wing moves arcuately upwardly or downwardly to move the load center of gravity longitudinally forwardly or rearwardly to control load pitch. An optional lower section controls load height during unloading. A hoist band passing through a pulley system with actuators that variably space the pulleys variably controlling effective band length.
    • 该装置稳定了直升机下的负载,以防止不期望的负载运动,同时允许负载重心的飞行中优化以减少阻力并增加银行能力和最高速度。 固定支架将设备固定在直升机上。 该装置包括控制负载俯仰和横向运动的上部部分和在卸载期间控制负载高度的下部分。 节距调节器包括具有由中空轴和电梯穿过的上和下轴环的c形轭。 横向移动调节器包括联接器和y形底盘。 联轴器包括一个中心套筒,该中心套筒位于上部和下部套环之间,允许围绕电梯选择性旋转的电机。 底盘通过一个球窝和一个中间悬挂系统固定在联轴器上,并夹在联轴器和悬挂板之间。 间隔的终端机架臂通过轴承座支撑负载。 绞车用一根脚踏的负载停止电缆。 脚前端可枢转地固定到俯仰调节器,而后部枢转地固定到翼。 机翼和电梯控制负载间距。 当电梯收起或延伸时,机翼向上或向下弧向运动,以便使负载重心纵向向前或向后移动以控制负载间距。 可选的下部控制卸载期间的负载高度。 通过具有致动器的带轮系统的起重带,其可变地空间使滑轮可变地控制有效带长度。

    • The invention relates to a force limiting unit for use in a motor vehicle, which is designed for setting the absorption of a force occurring in a dangerous situation in the motor vehicle between two parts moving relative to one another. The force limiting unit comprises a kinematic energy absorption device with a design that, in the event of a predetermined profile of the speed difference of the parts moving relative to one another during the dangerous instance, enables different force limiting levels to be realized according to the mass of the moving parts and the momentum occurring during the dangerous instance. The force limiting device for a self-locking belt retractor is comprised of a belt shaft, which holds the belt and is mounted inside a housing. The mass system, which responds to the rotation of the belt shaft in an unwinding direction, consists of a number of two-armed pendulum masses (16), which are distributed over the periphery of the belt shaft and which are mounted in a manner that enables them to swing around a center bearing point (17) fixed to the housing. The pendulum masses, in both final positions of their swinging movement, engage with a tooth (19) located at their ends inside the external toothing (15) of a toothed ring (13) that, during the dangerous instance, is to be coupled to the belt shaft and rotate therewith. The pendulum masses engage inside the external toothing in such a manner that the oscillation of the respective pendulum mass (16) is generated during the rotation of the toothed ring (13) relative to the pendulum masses (16) by the sliding of the tooth flanks of the teeth (19), which are formed on the pendulum masses (16), on the tooth flanks of the external toothing (15) of the toothed ring (13).
