Car seat with an adjustable surface area

摘要

The seat comprises several swivelling pins parallel with each other and about which the seat nose pivots successively from a given position to a following one, while the seat nose has the general shape of a polygon, the successive sides of which have increasing lengths. The position of said pins in relation to said sides is such that the seat nose surface facing upwards in each one of said positions is substantially in prolongation of the top surface of the cushion and in close proximity to it.
