Bucket seat with changing kinematics
First Claim
1. A seat for a vehicle, comprising:
- a bucket comprising a seat base and a backrest integral with or rigidly fixed to the seat base;
a supporting structure on which the bucket is fixed;
fixings to fix the supporting structure to a vehicle structure, a height of the bucket on the supporting structure being adjustable;
the supporting structure comprises;
a lower sub-assembly which forms a seat subframe and of which at least one bucket support is mounted movable in height in a substantially vertical direction determined by at least one lower guide rail, fixed in a seat reference system, of a lower structure;
an upper sub-assembly assembled with the lower sub-assembly and movable in rotation relative to the lower sub-assembly around a pivot axis which is substantially perpendicular to a plane of symmetry XZ of a seat assembly, the pivot axis is situated on the lower sub-assembly in a zone close to a lower end of said at least one lower guide rails and the pivot axis is situated on the upper sub-assembly in a zone close to a lower end of the upper sub-assembly;
the upper sub-assembly comprises at least one upper guide rail which is substantially vertical and situated above said at least one lower guide rail;
the bucket is fixed to the bucket support in an articulated manner at the seat base around an axis perpendicular to the plane of symmetry of the seat assembly; and
the bucket comprises at least one guide element fixed to the backrest and sliding in said at least one upper guide rail.

Abstract
A seat having a bucket and a supporting structure on which the bucket is fixed. The height of the bucket on the supporting structure is adjustable. A lower sub-assembly of the supporting structure forms a seat subframe and of which at least one bucket support is mounted movable in height following at least one lower guide rail. An upper sub-assembly of the supporting structure is assembled movable in rotation relative to the lower sub-assembly around a pivot axis which is situated close to a lower end of the lower guide rails and situated close to a lower end of the upper sub-assembly. The bucket is fixed to the bucket support in an articulated manner at the seat base and has at least one guide element fixed to the backrest and sliding in an upper guide rail of the upper sub-assembly situated above the lower guide rails.
