BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel chair, and more particularly, to an anti-collision wheel chair that prevents it from being turned on a ramp and an unpackaged road.

Generally, a wheelchair is a chair equipped with wheels on both sides so that a person who is inconvenient in behavior or inferior in function can move while sitting, helps to move to a desired place without help of another person.

Conventional wheelchairs, which are conventionally used, are easy to move on a flat ground, but can not be driven in an inclined environment such as a staircase, an escalator, and a ramp, or there is a risk of the wheelchair being turned over. Death or injuries are caused by the evacuation of the wheelchair. Therefore, a wheelchair is required to be used in a sloping environment such as a staircase and an escalator in order to prevent personal injury to the wheelchair.

Korean Patent Laid-Open No. 10-2010-0013892 discloses a technique relating to a wheelchair that can travel in an inclined environment as described above.

However, such a wheelchair has been developed to enable longitudinal attitude control to climb stairs or escalators. Thus, there is a risk of lateral conduction if the ramp is angled transversely or if the center of the occupant is disturbed.

On the other hand, in addition to the sloping environments such as stairways and escalators, there is a risk of falling on unpaved roads, uneven roads, and uneven roads. On uneven roads, the passengers' posture control is not smooth and the center is easy to be disturbed, causing the wheelchair to fall and causing personal injury. Also, since the terrain is not flat, the wheelchair can not be smoothly driven, resulting in difficulty in running. Therefore, a wheelchair that can be safely driven on all terrain is required.
