Abstract
Abstract A front seat assembly for motor vehicles is supported at the front by a first support which includes two lower guides in which support members are mounted for longitudinal movement. The latter are, in turn, engaged at their upper ends for movement relative to upper guides fixed to the front part of the seat cushion. The support members can be locked in the lower guides in a rearwardmost position while the position with respect to the upper guides can be chosen from a plurality of fixed adjustment positions. The rear part of the seat is supported by two pivotable arms which, when the seat is moved towards a forwardmost position, cause the cushion to be raised gradually, so that the visual point is substantially maintained. To facilitate access to the rear seats, the backrest can be tipped forwards by disengagement of a retaining member which hold the backrest in a fixed position relative to the cushion and of the retaining member which hold the support members within the lower guide. As well as tipping the backrest forward, the whole set is thus displaced forwardly.
