2.8 Brief about Invention A longitudinal adjuster for a vehicle seat includes a displacement sensor , which can interact with a seat rail, and a control signal emitter , which can be displaced in relation to the displacement sensor . The relative movement of the signal emitter  in relation to the displacement sensor reproducing, from a starting position, the longitudinal displacement carried out. The control signal emitter  is subjected to a control torque, at the latest once the stored longitudinal position of the seat has been reached, and then controls at least one blocking element which interacts with the seat rail by way of a control spring . A control bearing  is arranged between the control signal emitter and the control spring, which guides the control signal emitter  and which supports the control spring
