Adjustable seat device for a vehicle, comprising: -a base portion (10), -a seat portion (20) that is movable with respect to the base portion (10) between a first position, referred to as retracted, and a second position, referred to as extended, -an articulation system (30) forming a deformable parallelogram, which is connected to the base portion (10) and to the seat portion (20) and comprises at least one diagonal support arm (31) connected diagonally to the deformable parallelogram, characterized in that the diagonal support arm (31) is designed to have a first length when the seat portion (20) is in the first position and a second length when the seat portion (20) is in the second position.

A bench seat assembly that includes a first seat that includes a seat portion and a back, a second seat that includes a seat portion and a back, and a center portion positioned between the first and second seats. The first seat is bifurcated by a first vertical plane, the second seat is bifurcated by a second vertical plane, and the center portion is bifurcated by a center vertical plane. The first seat is angled outwardly such that the first plane defines a first acute angle with the center plane and the second seat is angled outwardly such that the second plane defines a second acute angle with the center plane. The first acute angle and the second acute angle are approximately the same.

A child car seat is selectively movable between a stowed configuration in a storage area defined by a base portion of a rear passenger seat of an automobile and a deployed configuration positioned against the rear passenger seat.

The service door is connected to one of the seat base and the seat back at a first hinged connection. The center seat back is configured to have a fold down, service position where the service door pivoted at the first hinged connection is located above the seat base to provide access to an area rearward the seat back in a front-rear direction of the vehicle seat. The service door is prevented from moving to the fold down, service position with the panel located beneath the service door.
