Definitions

  • the disclosure relates to a chair frame, and more particularly to a chair frame of a wheelchair.
  • an impact force may suddenly be generated during operation of the pneumatic cylinder, which may send bounces to the chair frame, so the user sitting in the wheelchair may be startled or feel unsafe.
  • disposing the pneumatic cylinder at the rear side of the base portion reduces the space for accommodating the user's personal belongings and adversely affects operation of the pneumatic cylinder as the personal belongings may block the pneumatic cylinder.
  • the base unit 1 includes a base frame 11 and two pivot seats 12.
  • the base frame 11 includes two front rod portions 111 that are elongated in a front-rear direction (Y), two first rear lower rod portions 112 that are connected respectively to the front rod portions 111 and that extend rearwardly, and two second rear lower rod portions 113 that extend rearwardly and respectively from the front rod portions 111 and that are located respectively under the first rear lower rod portions 112.
  • the base frame 11 further includes a first transverse rod portion 114 that is connected between the first rear lower rod portions 112, a second transverse rod portion 115 that is connected between the second rear lower rod portions 113, and a third transverse rod portion 116 that is connected between the front rod portions 111.
  • the operating rod 31 is a pneumatic linkage or a hydraulic linkage
  • the first articulating set 32 is movable relative to the second articulating set 33 during operation of the operating rod 31.
  • the chair frame of the wheelchair is capable of buffering the impact force generated during operation of the driving unit 3 that drives the seating unit 2 to pivot, and reducing bounces to thereby provide a relatively comfortable seating experience.
  • the driving unit 3 is disposed at the front side of the base unit 1, better utilization of a space near a rear side of the base unit 1 for accommodating other components of the wheelchair or personal belongings of the user may be achieved.
