This vehicle seat control device is provided with a storage unit, a position detection unit, a control unit, and an operation order setting unit. The space on a seat occupied by a passenger sitting in the seat is a sitting passenger-occupied space, and during the execution of an automatic operation, the operation order setting unit is configured to set the operation order such that position adjustments of seat elements operated in the direction of advancing into the sitting passenger-occupied space are started at the same time as, or are started after, the starting of the position adjustments of the seat elements operated in the direction moving away from the sitting passenger-occupied space.

A seat adjustment apparatus for a vehicle includes: a set bracket having a rear part to which a back frame is rotatably connected; and a cushion frame disposed on an upper side of the set bracket and to be tilted by a link mechanism. In particular, the link mechanism includes: a first link member which is hinge-engaged with a front part of the set bracket, connected to a driving unit and supports a front part of the cushion frame to make the front part of the cushion frame ascend and descend by the driving unit; a second link member hinge-engaged with a rear part of the set bracket and the cushion frame to guide the rear part of the cushion frame; and a third link member hinge-engaged with the set bracket and the cushion frame to determine a tilting position of the cushion frame when the cushion frame ascends.

The invention relates to a vehicle seat arranged to be adjusted between a forward facing/rearward facing setup. The vehicle seat comprises a seat back and a seat cushion arrangement comprising a seat cushion arranged to be attached to a seat structure, a front pivoting notch and a rear pivoting notch. The seat back comprises a first and a second seat back connection arranged on a seat back side arranged to be releasably engaged with a first and second latch respectively. The first seat back connection is arranged to releasably engage with a first latch when the vehicle seat is in the forward facing setup, and the second seat back connection is arranged to releasably engage with a second latch the vehicle seat is in the rearward facing setup.

It is provided an adjusting device for the longitudinal adjustment of a vehicle seat, comprising at least one rail for defining a longitudinal seat axis along which a seat base of the vehicle seat is adjustable, and for supporting at least one adjusting unit of the adjusting device, and at least two shiftably guided adjusting units arranged one behind the other along the longitudinal seat axis, to which the seat base is to be fixed in order to be adjustable along the longitudinal seat axis. The at least two adjusting units are adjustable relative to each other along the longitudinal seat axis, and each adjusting unit is assigned a separate drive for the power-operated adjustment along the longitudinal seat axis.
