Device and method for recognizing the occupancy of a seat
First Claim
1. A device for recognizing the occupancy of a seat in which for detecting a force acting on a seat surface a sensor installation is provided so that the force can be classified for recognition, characterised in that the sensor installation comprises two sensor mats which each independently of one another detect the pressure exerted on them, wherein said two sensor mats are juxtaposed and shaped to cooperatively encompass a substantial portion of the seat surface,wherein said two sensor mats comprise a generally U-shaped outer mat including a main portion and two spaced leg portions extending therefrom, and a generally U-shaped inner mat including a generally square main portion and two spaced arm portions extending therefrom towards the main portion of said outer mat.

6. A method for recognizing the occupancy of a seat in which:
-
two sensor mats located in the seat each emit a pressure signal, wherein said two sensor mats are iuxtaposed and shaped to cooperatively encompass a substantial portion of the seat, wherein said two sensor mats comprise a generally U-shaped outer mat including a main portion and two spaced leg portions extending therefrom, and a generally U-shaped inner mat including a generally square main portion and two spaced arm portions extending therefrom towards the main portion of said outer mat; and the pressure signals are evaluated singly. - View Dependent Claims (7, 8, 9)

10. A device for recognizing the occupancy of a seat in which for detecting a force acting on a seat surface a sensor installation is provided so that the force can be classified for recognition, characterized in that the sensor installation comprises two sensor mats which each independently of one another detect the pressure exerted on them,
wherein said sensor mats are characterised by an inner and an outer sensor mat, wherein the inner mat has a substantially closed surface area and is surrounded by the outer mat in semicircular or U-shaped manner including a main portion and two spaced leg portions extending therefrom, wherein said inner mat is generally U-shaped, having a square main portion and two spaced arms extending therefrom towards the main portion of the outer mat, and wherein said outer mat leg portions and inner mat arms are substantially parallel and extend in opposed directions.
