Abstract: This vehicle (2) usable by a physically handicapped or able-bodied person, in particular for athletic or recreational activities, comprises a seat (4) made from monobloc plastic material and at least two main wheels (6), the seat (4) comprising a seat bottom (40), a backrest (42) and lateral rims (43). The seat (4) has a cavity (18) extending below the backrest (42) and the seat bottom (40) and an opening passing through the seat (4) between the cavity (18) and a rear part of the backrest (42), the cavity (18) and the opening being intended to accommodate a backrest of a seat (4) of a second identical vehicle positioned below said vehicle (2), such that at least two identical vehicles (2) are stacked stably one on top of the other.

Abstract: The invention relates to a vehicle (1) including a user seat comprising a backrest (3), a seat portion (4) and lateral edges (5) provided on both sides of the seat portion. The vehicle has a reduced production cost and a structure that facilitates the adaptation thereof to a plurality of activities, in particular owing to the fact that the seat, which is made from plastic, is produced in the form of a single piece, the lateral edges (5) being extended downwards such as to form two rear conduits intended to receive at least one rear movement member (26, 27, 28). The invention also relates to a vehicle production method in which rotational molding is used to form an ergonomic seat.
