Patent ID: 7077416

Claim:
A locomotion device for physically disabled persons, characterized in that it comprises: a chassis ( 10 ) mounted onto a pair of rear wheels ( 11 ) and a pair of front swiveling wheels ( 12 ), said chassis ( 10 ) carrying a motor assembly for the selective drive of the rear wheels ( 11 ); a seat frame ( 20 ) frontally articulated to the chassis ( 10 ), so as to be displaced between a substantially horizontal first position and a second raised position that is markedly downwardly forwardly inclined; a backrest frame ( 30 ), which is inferiorly articulated to a rear portion of the seat frame ( 20 ) and to the chassis ( 10 ), in order to be displaced between a first position, which is substantially orthogonal to the seat frame ( 20 ), and a second position, which is substantially coplanar to said seat frame ( 20 ), when the seat frame ( 20 ) is displaced between the first position and the second position, respectively; an impelling means ( 40 ), which is operatively coupled to the chassis ( 10 ) and to at least one of the seat frame and backrest frame ( 20 , 30 ), in order to provide the selective displacement of the seat frame ( 20 ) between its first position and its second position; a movement locking means ( 50 , 50 ′), which is mounted to the chassis ( 10 ) to allow the selective locking of the rear wheels ( 11 ); a position locking means ( 60 ), which is mounted to the chassis ( 10 ) and operatively associated to the seat frame ( 20 ), in order to maintain the latter in any operational position between the first position and the second position, and a raising structure ( 80 ) carrying a respective armrest ( 83 ) and which is provided lateral and external to each adjacent seat frame ( 20 ) and has a rear end ( 81 ) articulated to the backrest frame ( 30 ) and a front end ( 82 ) articulated to the chassis ( 10 ) at a point backward of the articulation point of the seat frame ( 20 ) to the chassis ( 10 ), the impelling means ( 40 ) being operatively associated with the backrest frame ( 30 ) through the pair of raising structures ( 80 ).
