摘要： A power wheelchair with front anti-tip wheels for substantially eliminating partial tips of the wheelchair is described. The anti-tip wheels are attached to the end of an extension arm which is attached to the frame of the wheelchair. A spring connects the anti-tip wheels with the frame at a second point. The spring tends to hold the anti-tip wheels in a neutral position at a predetermined height above the ground. A lowering mechanism is provided which positions the anti-tip wheels in a position engaged with or just above the ground. A retaining system holds the anti-tip wheels on or near the ground until the user or a release trigger device releases the retaining system, at which time the anti-tip wheels return to the neutral position. While the retaining system is disengaged, the wheels are free to rise in response to an upward force in order to climb over an obstacle in the wheelchair's path of travel.
摘要翻译：描述了具有用于基本上消除轮椅的部分尖端的前防倾斜轮的电动轮椅。反头轮附接到附接到轮椅的框架的延伸臂的端部。弹簧在第二点将反尖端轮与框架连接起来。弹簧倾向于将防倾斜轮保持在地面上方预定高度的中立位置。提供一种降低机构，其将反尖端轮定位在与地面接合或刚好在地面上方的位置。保持系统将防倾斜轮保持在地面上或附近，直到使用者或释放触发装置释放保持系统，此时反尖端轮回到中立位置。当保持系统脱离时，轮子响应于向上的力而自由上升，以便爬过轮椅行进路径中的障碍物。

摘要： A power wheelchair is provided having one or more anti-tip wheels for stabilizing the movement of the frame about the drive wheels. An anti-tip wheel is attached to the end of a suspension arm which is pivotally attached to the frame of the wheelchair. A spring resiliently supports the anti-tip wheel in a neutral position relative to the ground upon which the drive wheels of the wheelchair normal ride. A retaining system selectively fixes position of the anti-tip wheels relative to the frame. The retaining system employs a plurality of teeth, with one portion disposed in combination with said suspension arm, and at least one other tooth disposed for engaging said one portion to provide unidirectional retention of the position of said suspension arm relative to the frame. The engagement of the teeth to lock the position of the suspension arm may be responsive to the torque generated by the motor.
摘要翻译：电动轮椅设置有一个或多个防倾斜轮，用于稳定框架围绕驱动轮的运动。安装在轮椅的框架上的悬挂臂的端部安装一个反头轮。弹簧弹簧地将反尖齿轮支撑在相对于地面的中立位置，轮椅的驱动轮正常行进。保持系统选择性地固定防倾斜轮相对于框架的位置。保持系统采用多个齿，其中一个部分与所述悬架臂组合设置，并且至少一个其他齿设置成用于接合所述一个部分，以提供所述悬架臂相对于框架的位置的单向保持。齿的接合以锁定悬架臂的位置可以响应于由电动机产生的扭矩。

摘要： A stabilizing system for a reclinable wheelchair connects anti-tip members to the wheelchair seat such that pivoting of the seat causes pivoting of the anti-tip members. In one embodiment, the stabilizing system includes cables connected at opposite ends to the seat and to the anti-tip members. The cables may be connected to the seat bottom or, alternately, to the seat back. The anti-tip members may incorporate a pivoting suspension member that includes a drive motor for the wheelchair. Pivot control mechanisms connected to the cables can be used to permit a predetermined amount of seat pivot without corresponding pivot of the anti-tip members. The stabilizing system alternatively includes axially compressible link members connecting the seat back to the anti-tip members to provide controlled pivoting of the anti-tip members based on pivoting of the seat.
摘要翻译：用于可倾斜轮椅的稳定系统将反尖端构件连接到轮椅座椅上，使得座椅的枢转引起反尖端构件的枢转。在一个实施例中，稳定系统包括在相对端部处连接到座椅以及连接到防顶部构件的电缆。电缆可以连接到座椅底部，或者可以连接到座椅靠背。防顶部构件可以包括枢转悬挂构件，其包括用于轮椅的驱动马达。连接到电缆的枢转控制机构可以用于允许预定量的座椅枢轴，而不具有反尖端构件的相应枢轴。稳定系统可选地包括将座椅靠背连接到防顶部构件的轴向可压缩连杆构件，以基于座椅的枢转来提供防顶部构件的受控枢转。
