Publication number: 20110046524Abstract: A passive exercise apparatus in this invention comprises a base, a seat, a driving unit, and a pair of footrests. The seat is disposed on the base. The driving unit is configured to reciprocate the seat past its neutral position relative to the base. A pair of the footrests is arranged on the base at a front of the seat and is spaced from the seat by a predetermined distance. The feature of the invention resides in that the each of the footrests has a top face for contact with a user's foot. Each of the footrest is configured to move the top face between a raised position and a lowered position. The top face is elastically urged toward the raised position.Type: ApplicationFiled: April 17, 2009Publication date: February 24, 2011Inventors: Izumi Mihara, Wataru Sanematsu, Taketora Nakamura, Toshio Nakano, Yutaka Yamada, Youji Kawamoto, Yukihiko Kitano
