Longitudinal adjuster for a vehicle seat
First Claim
1. A longitudinal adjuster for a vehicle seat, the longitudinal adjuster comprising:
- a first seat rail fixed to vehicle structure and arranged on a vehicle floor, the first seat rail having a flat area comprised of at least one of an integral first rail flat area, which is adjacent to the floor and extends along a longitudinal direction of the rails to an end corresponding to an end of the first seat rail and a connected flat area, which is connected to the first seat rail and positioned adjacent to the floor and extends along the longitudinal direction of the rails to an end corresponding to an end of the first seat rail;
a second seat rail fixed to the seat and displaceable in relation to the first seat rail and guided in same;
a position detection means with a sensor having a magnet and a Hall element, wherein;
the sensor is arranged in the interior of the second seat rail fixed to the seat;
the sensor is aligned in a direction of a flat area of the first rail;
the flat area forms a detection area;
the sensor detects an end of the detection area, the sensor having a detection range including a certain detection range and an uncertain detection range; and
the distance between the sensor and the detection area lies within the certain detection range of the sensor; and
the distance between the sensor and the vehicle floor lies outside of the certain detection range and outside the uncertain detection range of the sensor.

Abstract
A longitudinal adjuster for a vehicle seat (3) has a first seat rail (5) fixed to the vehicle structure and arranged on a vehicle floor (10) and a second seat rail (8) fixed to the seat and displaceable in relation to the first seat rail (5) and guided in same. A position detection device (20) is provided with a sensor (24), having a magnet and a Hall element. The sensor (24) is arranged in the interior of the second seat rail (8) and aligned with a flat area associated with the first seat rail (5) in which one end of the flat area corresponds to the end of the rail and the flat area forms a detection area. The sensor (24) is used to detect an end of the detection area. The sensor (24) has a certain detection range and the distance between the sensor (24) and the detection area lies within the certain detection range of the sensor (24). The distance between the sensor (24) and the vehicle floor (10) lies outside of the certain detection range of the sensor (24).
