Vehicle seat assembly comprising a removable seat assembled on guide rails

A vehicle seat assembly comprising:

• at least one first guide rail including a fixed section which is intended to be integral with a vehicle floor and which extends in a longitudinal direction, said fixed section comprising a longitudinal edge, and a seat having at least one first foot which is assembled in a removable manner on the guide rail to enable the seat to be vertically detached from the guide rail, said first foot comprising a coupling lock which is movable between a locked position where said coupling lock engages with the guide rail and a withdrawn position where said first foot can separate vertically from the guide rail, said seat having a control device for moving said coupling lock between said locked and withdrawn positions, wherein the coupling lock includes a first jaw part which extends downward from said foot to form a coupling claw, the first jaw part being pivotally mounted about a jaw rotation axis parallel to the longitudinal direction, said coupling lock engaging under said longitudinal edge of the fixed section when the coupling lock is in the locked position, thus preventing vertical separation of said first foot and the fixed section, and said coupling claw being sufficiently separated from the fixed section when the coupling lock is in the withdrawn position so that the coupling claw does not interfere with said fixed section during vertical separation of said first foot and said fixed section, and wherein said longitudinal edge of the fixed section delimits an open space which is situated underneath said longitudinal edge, said open space being arranged to enable said coupling claw to move in said open space during longitudinal movement of the seat.
