Patent ID: 8258417

Claim:
A seating detection switch comprising; a film-form substrate; and a plurality of contacts forming contact pairs to act as at least two switch elements actuatable by pressure generated by the seating of a person, the contact pairs including a first contact pair acting as a first switch element and a second contact pair acting as a second switch element and the contact pairs being allocated to a surface of a seat with a certain distance therebetween in such a way that the first contact pair is allocated to a first area of the seat and the second contact pair is allocated to a second area of the seat, wherein the first contact pair comprises a first contact provided at one end of a first conductor and a third contact provided at one end of a third conductor, wherein the first conductor comprises a first terminal provided at other end thereof, wherein the first contact and the third contact are insulated from each other, wherein the second contact pair comprises a second contact provided at one end of a second conductor and a fourth contact provided at the other end of the third conductor, wherein the second conductor comprises a second terminal provided at other end thereof, wherein the second contact and the fourth contact are insulated from each other, wherein the first contact, the third contact, the second contact and the fourth contact are fixed to the same surface of the film-form substrate, wherein detection of the seating of the person requires that the first contact becomes mutually conductive with the third contact and the second contact becomes mutually conductive with the fourth contact and the seating detection switch comprises AND circuits as a condition for the detection of the seating of the person, and wherein the contacts of the first contact pair and the contacts of the second contact pair are connected in series.
