VEHICLE SEAT

The invention relates to a vehicle seat having a seating portion and a backrest portion being pivoting connected with one another via a seat recliner mechanism, the vehicle seat comprising an angle measurement system including a sensor assembly by means of which the tilt adjustment of the backrest portion in relation to the seating portion can be determined. The invention provides that the angle measurement system is provided with a shifting mechanism on the seating portion and one on the backrest portion, where the shifting mechanism on the seating portion is provided with a shifting element which is supported movable along a first shifting direction, and the shifting mechanism on the backrest portion is provided with a shifting element which is supported movable along a second shifting direction, where the shifting elements are swiveling coupled together in a pivot point so that in the event of a tilt adjustment of the backrest portion an angle (α) between the two shifting elements changes, and the sensor assembly is configured to put out a sensor signal depending on the angle (α).
