Automobile seat occupant sensing unit and vehicle seat fitted therewith
First Claim
1. An automobile seat occupant sensing unit with a sensor, said sensor comprising a sensor body and at least one resistance strain gauge said sensor body being provided with a main part and with at least one arm projecting from said main part, said main part being fitted with a fastening means for mounting the sensor, said main part having a supporting surface, the at least one arm a) being elastically deformable in a direction transverse to the supporting surface, b) having a bearing area pointed toward a direction opposite the supporting surface and c) carrying the at least one resistance strain gauge which strain gauge is accommodated between the bearing area and the main part and which strain gauge senses an elastic deformation of the at least one arm, said deformation being occasioned by the presence of an occupant in a vehicle seat equipped with said automobile seat occupant sensing unit.

Abstract
The automobile seat occupant sensing unit has a sensor. The sensor consists of a sensor body and of at least one resistive strain gauge. The sensor body is provided with a main part and with at least one arm projecting from said main part. The main part is fitted with a fastening means for mounting the sensor and has a supporting surface. The at least one arm is elastically deformable in a direction transverse to the supporting surface, has a bearing area pointed toward a direction opposite the supporting surface and carries the at least one resistive strain gauge which is accommodated between the bearing area and the main part and which senses an elastic deformation of the at least one arm, said deformation being occasioned by the presence of an occupant in the vehicle seat.
