摘要： Attachments for a manual wheelchair are provided for navigating a wheelchair over obstacles and uneven terrain, such as a typical curb on a street. The attachments provide for regulating the movement of the wheelchair as the wheelchair descends the curb and to prevent the wheelchair from flipping over during such movement. The attachments include a front caster wheel slider assembly on each side of the wheelchair, a follower wheel assembly and a track belt damping bar. The front caster wheel slider assembly includes a piston that will quickly push the front caster wheels down after they roll over the top edge of the curb. The follower wheel assembly acts as a sensor that will release the piston in the assembly after the front caster wheels roll over the top edge of the curb. As the back wheels of the wheelchair roll over and down the curb, the track belt damping bar slows the descent of the wheelchair.

摘要： The present invention provides a sensor for detecting the angle of an incline, such as a staircase, before it is reached by the wheelchair. A control signal is provided to a motor for tilting the seat to cause the seat to be tilted to a predetermined minimum safe angle before the wheelchair reaches the staircase. The minimum safe angle is an angle of tilt at which the wheelchair will not roll over if the tilting mechanism should fail to completely rotate the seat to a horizontal position and as the stairs are descended. The minimum safe angle is determined by the position of the center of gravity of the wheelchair which is affected by the users weight. If the seat does not achieve this minimum tilt, the wheelchair is prevented from going over the stairs.

摘要： A latch for each of a pair of cushioning arms, respectively, of a stair-climbing wheelchiar. The latch for each arm includes a first member coupled to the arm and a second member coupled to a fixed support of the wheelchair, with the second member being coupled to the armature of a solenoid which is energized to unlatch the arm from latched relationship with the support when it is desired to use the arm for cushioning purposes. An ultrasonic transducer coupled to the wheelchair adjacent to each latch, respectively, provides signals to energize the respecting latch solenoid when the arm is to be unlatched. To latch each arm, the adjacent edge margins of the two members are bevelled so that, during upward movement of the arm, such as by movement of the wheelchair from an inclined position to a horizontal position, the members are spread apart and a first spring biases the two members back together in coupled relationship to each other. When the latch solenoid is energized, the second member is moved away from the first member to allow a second spring to pull the arm down and into an unlatched position. A limit switch senses when each arm is latched.

摘要： A stair-climbing wheelchair having a sensor at the front end thereof for sensing the presence of a stair step or an inclined ramp. The sensor emits signals which reflect from a surface and to a receptor in the sensor, the receptor being coupled to a microprocessor which determines not only the linear distance traveled by the wheelchair in a forward direction, but also the height of a stair step. Thus, when the tracks are down, a microprocessor associated with the sensor will shut off the drive motors to the tracks if the slope of the stairway is too great when the tracks are down. In such a case, the wheelchair backs away from the stairway and does not go down it. If the slope is less than a predetermined value, such as 30.degree.-35.degree., the wheelchair can move down the stairway in the normal fashion.
