    • A safety harness to restrain the operator of an earthmoving vehicle. The harness includes a pelvis belt connected to respective shoulder belts, each end of the pelvis belt and the shoulder belts are connected to belt retractors lockable by means responsive to both belt speed and the inclination of a vehicle. The vehicle inclination response of each retractor is similar, so that they act simultaneously, and a device is provided for adjusting the vehicle inclination response independently of the belt speed response to give the operator freedom of movement with safety restraint. The device may be coupled by cables to respective levers for locking the retractors, disabling the vehicle inclination response or for making the vehicle inclination response effective or by a double-acting solenoid having an armature for achieving the same effect.
    • 用于限制土方工程车辆操作人员的安全带。 线束包括连接到相应的肩带的骨盆带,骨盆带的每个端部和肩带连接到能够响应于皮带速度和车辆倾斜度的装置而可锁定的带收缩器。 每个牵开器的车辆倾斜响应是相似的,使得它们同时作用,并且提供了一种用于独立于皮带速度响应来调节车辆倾斜响应的装置,以使驾驶员具有安全限制的运动自由度。 该装置可以通过电缆耦合到相应的杠杆,用于锁定牵开器,禁止车辆倾斜响应或使车辆倾斜响应有效,或通过具有用于实现相同效果的电枢的双作用螺线管。
