Sensor system for detecting the adjustment position of a vehicle seat
First Claim
1. A sensor system for detecting the adjustment position of a vehicle seat, by which a relative adjustment of an at least partially ferritic upper rail, moveable lengthwise along a longitudinal extension of an at least partially ferritic stationary lower rail, at least in two adjustment positions, namely a forward adjustment position and a rearward adjustment position, will be detected, the sensor system comprising:
- a Hall sensor, and a first preloaded magnet, free of flux concentrators and shielding sheets, whereby the Hall sensor and the first preloaded magnet are arranged along a longitudinal extension of the upper rail that is moveable lengthwise in such a way that during an adjustment of the upper rail relative to the stationary lower rail, passage of a free longitudinal end of the lower rail will be monitored and will result in a change of an output signal of the Hall sensor corresponding to a change from the forward adjustment position to the rearward adjustment position of the vehicle seat and vice versa, the sensor system being configured in such a way that in the unmounted state, and output signal corresponding to a reatward adjustment position of the vehicle seat will be generated at the Hall sensor.

Abstract
A sensor system for detecting an adjustment position of a vehicle seat, the sensor system having a Hall sensor and a first preloaded magnet, and it is free of flux concentrators and shielding sheets. The Hall sensor and the first preloaded magnet are arranged along a longitudinal extension of the upper rail that is movable lengthwise such that during adjustment of the upper rail, passage of a free longitudinal end of the stationary lower rail will be monitored and result in a change of an output signal of the Hall sensor.
