Description

Technical Field

[0001] The present invention relates to the technical field of vehicle seats, and more specifically to a rotary separable vehicle seat. Background Art

[0002] At present, in the market, most vehicle seats used by the elderly, patients and disabled people with inconvenient mobility are directly fixed on a rotary lifting device. When the rotary lifting seat descends to the same level as the wheelchair, the user of the wheelchair is transferred from the seat to the wheelchair. It is inconvenient to use, and it is necessary to carry and place the user on the wheelchair.
