20080246251 | WHEELCHAIR ATTACHMENTS - 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 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. | 10-09-2008 |

20120175850 | Wheelchair Attachments - 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 belt support frame, at least two rollers mounted on the belt support frame and a belt mounted around the at least two rollers. The belt support frame is adapted for mounting on the frame of the wheelchair such that as the wheelchair descends from the upper surface to the lower surface, the belt engages an edge of the upper surface and rolls around the at least two rollers slowing a descent of the wheelchair from the upper surface to the lower surface. | 07-12-2012 |
