Patent number: 8114034Abstract: A walking aid apparatus comprising a sitting member which a user sits astride and leg links each coupled to a connection provided on the undersurface of the sitting member in such a way as to be free to swing in the forward/backward direction, which improves the stability of the sitting member. The connection is adapted in such a way that a forward/backward swinging fulcrum of the leg links is located above the sitting member. More specifically, the connection is provided with an arc-shaped guide track longitudinal in the forward/backward direction and having the center of curvature above the sitting member, so that each of the leg links swings along the guide track in the forward/backward direction. If the leg links are allowed to swing freely also in the lateral direction, preferably the lateral swinging fulcrum of the leg links is also located above the sitting member.Type: GrantFiled: May 29, 2006Date of Patent: February 14, 2012Assignee: Honda Motor Co., Ltd.Inventors: Yasushi Ikeuchi, Tatsuya Noda, Jun Ashihara, Yutaka Hiki
