Car detachable disabled seat

technical field

The present invention relates to the technical field of disabled seats, in particular to a vehicle-mounted detachable disabled seat.

Background technique

Wheelchairs are chairs with wheels that can help replace walking, and are divided into electric and manual folding wheelchairs. It is an important mobile tool for the wounded, sick, and disabled at home, for home rehabilitation, turnover transportation, medical treatment, and outings. Wheelchairs not only meet the needs of the physically handicapped and the disabled, but more importantly, they are convenient for family members to move and take care of patients. Allow patients to use wheelchairs for physical exercise and participation in social activities.

Ordinary wheelchairs are generally composed of a foldable frame, front and rear wheels, left and right knee pads and footrests, left and right detachable armrests, handle brakes, seats, backrests with medical imaging data bags, bedpans, urine bag hooks, and electric standing. On the basis of ordinary wheelchairs, the hand-cranked wheelchair adds a hand-cranked device. On the basis of ordinary wheelchairs, the electric wheelchair adds an electronic power assist system, which reduces the physical exertion of the user. Based on the electric wheelchair, the intelligent wheelchair adds positioning movement, standing movement, remote control movement and related Internet + assisted living.
