Method for controlling adjustment devices of a motor vehicle seat for adjustment of the seat
First Claim
1. Method for controlling plural adjustment devices of a motor vehicle seat, which devices are assigned to the longitudinal movement of the seat and the tilting movement of the seat back and are activated by positioning switching elements so as to move the motor vehicle seat into specific, set positions in cooperation with switching apparatus operatively cooperating with the seat back to block the associated adjustment device before the seat back runs into an obstacle lying in a range of adjustment of the seat, comprising the steps of(a) initiating a rearward tilting movement of the seat back by one of the positioning switching elements;
- (b) blocking of the adjustment device for the rearward tilting movement shortly before the seat back runs into the obstacle;
(c) moving the seat longitudinally forward automatically via the switching apparatus;
(d) moving the seat back out of a switching range of the switching apparatus again and, in addition to the longitudinal movement of the seat, continuing the rearward tilting movement of the seat back either until the next time blocking occurs or until a set lowered position of the seat back is reached; and
(e) stopping the longitudinal movement of the seat.

Abstract
A method controls adjustment devices of a motor vehicle seat. The devices are assigned to the longitudinal movement of the seat and the tilting movement of the seat back and are activated by positioning switching elements to move the motor vehicle seat into predetermined set positions. A switching device corresponding with the seat back blocks the associated adjustment device before the seat back runs into an obstacle lying in its range of adjustment. In order to optimize the motion sequences when a rearward tilting movement of the seat back is initiated by one positioning switching element, shortly before the seat back runs into the obstacle, the adjustment device is blocked from further tilting movement of the seat back and a longitudinal movement of the seat forward is automatically initiated by the switching device. The seat back thereby moves out of the switching range of the switching device again, and, in addition to the longitudinal movement of the seat, the rearward tilting movement of the seat back is also continued again, either until the next time blocking occurs or until the set lowered position of the seat back is reached, in which position the longitudinal movement of the seat is then also stopped.
