| 摘要 |
The present invention concerns an apparatus for adjusting the vertical and longitudinal position and the inclination of a pivotable seat part ( 2 ) of a vehicle seat ( 1 ) relative to a floor structure ( 4 ) of the vehicle, having a linkage that encompasses a linkage part, constituted by at least one articulated rectangle (ABCD), that has a base (AB), two rockers (BC, AD), and a coupler (CD). The base (B)is arranged in a plane extending substantially parallel to a longitudinal seat axis (X-X).The rockers (BC, AD)are pivotable about rotation axes extending substantially parallel to transverse seat axis. The linkage encompasses two linkage parts, each constituted by at least one articulated rectangle (ABCD;CDEF), that each have a base (AB,CD), two rockers (BC,AD;DE,CF),and a coupler (DC,EF). The base (AB)of the first linkage part is fixed with respect to the floor structure ( 4 )of the vehicle, the coupler (CD)of the first linkage part constitutes the base (CD)of the second linkage part, the coupler (EF)of the second linkage part is fixed with respect to the seat part ( 2 ), and a rocker (DE,CF)of the second linkage part is coupled in constrainedly kinematic fashion to a rocker (AD)of the first linkage part.
