Vehicle seat with in itself rotatable back rest and switchable transmission unit for allocating a drive torque between two longitudinal sides of the backrest

The present invention relates to a vehicle seat (F) with - a seating surface defining seat underframe (U) and a seat back (L), wherein the seat back (L) along a backrest longitudinal axis (B) and the backrest longitudinal axis (B) in a use position of the seat back (L), in which a person ( P) F) intended (on the vehicle seat to take place, extends at an angle to the backrest of the seat surface, and - a drive means having at least one drive unit (1) comprising a power-operated rotation of the backrest located in the use position (L) with respect to its backrest longitudinal axis (B) allows, in which a backrest longitudinal side of the seat back (L) with respect to a pivot axis (A) more to the rear inclined than the other longitudinal side of the backrest. According to the invention, a switchable gear unit (2) is at least provided by means of a by the drive unit (1) generated driving torque between the backrest longitudinal sides can be divided in order to rotate the seat back (L) with respect to its backrest longitudinal axis (B).
