The perambulator has a seat support (20) with a rear end articulated based on two degrees of freedom with respect to a backrest post (2). A front linkage (8), rear linkage (4), backrest linkage (1) and the support are articulated with respect to each other and jointly ensures tilting towards front of a lower end of a rear leg (5), tilting towards rear of a lower end of a front leg (9) and folding of the backrest against the seat during movement of the perambulator to a folded position. An upper edge of the backrest is located opposite to a support's front end and an upper end of the leg (9). |
