Description

Automobile rear seat device for handicapped persons

technical field

The invention relates to the field of automobile comfort and ergonomics, in particular to a fully automatic rear seat device for automobiles used by persons with disabilities.

Background technique

Automobile is one of the most convenient and efficient means of transportation at present. It is the most widely used means of transportation in the world and has a relatively large base. It will be irreplaceable at least in the next ten to twenty years. Traveling provides great convenience, but for the disabled and the elderly with inconvenient legs and feet, they often encounter great difficulties when getting on and off the bus. Therefore, there is an urgent need to add some humanized designs to better help disabled people return to society and participate in various social activities.

There are not many similar patents in China. Most of the existing patents are mechanically and manually pulling the seat out of the car door, or realizing the seat pushing function through hydraulic devices, chains and other mechanisms. Patent No. 200520136852.X discloses a car automatic However, the feasibility of this device is not high, because the seat back will interfere with the C-pillar of the car when the seat is pushed out entirely, and the push-out of a single seat brings great difficulties to the strength design, and the manual design is compatible with the electric control. Moreover, it is not convenient to operate. There are many designs for the seat itself, but the design for the seat to rotate is rare, and the research status at home and abroad is not optimistic. Although there are some patents, such as easy-to-reform steerable split car seats, mechanical barrier-free taxi seats, etc., the design of guide rails and bases is still not fine enough, and the general design is too idealized, so seldom get real patents.
