  • Publication number: 20070095580
    Abstract: A power wheelchair includes a pair of clutches, each coupled to a respective drive power source and a respective drive wheel, and a clutch control device that includes a pair of rod pivoting units, a control unit, and a flexible linking unit interconnecting the control unit and the rod pivoting units. The rod pivoting units are coupled to rotary control rods of the clutches, respectively. By operating the control unit, drive power transmission of the clutches can be controlled accordingly.

  • Publication number: 20070057561
    Abstract: A leg rest device for a wheel chair includes a coupling base, a rotary frame unit, a positioning unit, and a footrest. The coupling base is to be fixed to one side of a chair frame of the wheelchair, and defines a rod hole that extends along a hole axis. The rotary frame unit includes a coupling rod that is extended rotatably into the rod hole of the coupling base, and a leg frame member that is connected to and that extends forwardly from the coupling rod. The rotary frame unit is rotatable relative to the coupling base between a first position, where the leg frame member is disposed frontward relative to the coupling base, and a second position, where the leg frame member is disposed sideward relative to the coupling base. The positioning unit retains releasably the rotary frame unit at one of the first and second positions on the coupling base. The footrest is coupled to the leg frame member.

  • Patent number: 7150463
    Abstract: A wheelchair includes a chair frame, two suspension arms, two clutches, two drive wheels, two shock absorbers, and two limiting units. The chair frame includes two lateral frame parts. Each of the suspension arms is connected pivotally to the chair frame adjacent to a respective lateral frame part. Each of the clutches is mounted on a respective suspension arm. Each of the drive wheels is coupled to a respective clutch. Each of the shock absorbers is mounted between a respective lateral frame part and a respective suspension arm. Each of the limiting units includes a mounting seat mounted on a respective lateral frame part and formed with a guide slot unit therethrough, and a connecting component that extends through the guide slot unit and that mounts movably a respective suspension arm on the mounting seat.

  • Patent number: 6979229
    Abstract: An electrical connector assembly is adapted for interconnecting first and second conductors provided respectively on first and second vehicle components that are coupled removably to each other, and includes first and second electrical connectors. The first electrical connector includes a first insulator seat to be mounted on the first vehicle component, and a plurality of first contacts mounted on the first insulator seat and to be coupled electrically and respectively to the first conductors. The second electrical connector includes a second insulator seat to be mounted on the second vehicle component, and a plurality of second contacts mounted pivotally on the second insulator seat and to be coupled electrically and respectively to the second conductors. The second contacts are biased such that, when the first and second vehicle components are coupled together, the second contacts are able to establish tight electrical contact with the first contacts, respectively.
