Abstract s7 The mechanism is designed so that when the backrest (3) is reclined, the respective inclination changes may be transmitted in synchrony to the seat cushion (2). The seat as a whole rests upon a pair of parts (7) and (8) with the assistance of respective hinge pins (9) and (10). The pin (9) is positively fixed to a support (11) to which a gas spring (13) is hinged, its other end being linked to the backrest (3). When the backrest (3) is tilted back the rear cushion (2) area is lowered because the pin (18) hinging the backrest to a rod (17) linked to the pin (10) cannot rise, which is why the said backward and downward inclination tipping seat cushion (2) takes place.
- A mechanism for adjusting the inclination of a vehicle seat cushion, essentially characterised in that the said cushion structure, hinged to the backrest structure, rests its lower area upon a fixed and likewise front body, through a support and a pin that allows the said cushion to be tilted, whereas through its rear area it "hangs" from the lower end of the backrest structure, which in turn rests upon another fixed rear body, in particular through a rod that is hinged to the lower end of the backrest structure and a crankshaft mounted with freedom of rotation upon the fixed rear body, all so that when the gas or mechanical spring used to adjust the backrest position is released and the said backrest is folded back, the point at which the backrest structure is hinged to the said rod shall be tilted, which shall cause the rear cushion area to be lowered, in proportion to the degree of reclination of the backrest and in proportion in relation to the turning radius of the said rod.
