First Claim
Patent Images
1. A motor vehicle seat arrangement comprising:
- at least one seat having a seat cushion with a seating surface and a lower side facing away from the seating surface; and
a measurement arrangement includinga carrier fastened to a structural body element of a vehicle body, the carrier being formed by plastic and having a first modulus of elasticity;
a support layer positioned on the carrier on a carrier side opposite the structural body element and being formed by an elastomer, the support layer having a second modulus of elasticity, the first modulus of elasticity being at least twice the second modulus of elasticity; and
at least one sensor formed as a foil-like measurement layer on the support layer on a support layer side opposite the carrier and configured to detect a loaded state of the seat cushion by detecting at least one of a deformation or a force loading of the lower side of the seat cushion.

Abstract
The present invention relates to a measurement arrangement for detecting an occupancy of a motor vehicle seat arrangement with at least one seat, which comprises a sensor arrangement with at least one sensor (10) for detecting a deformation of a lower side (21) facing away from the seating surface or of a force loading by a lower side (21) facing away from the seating surface of a seat cushion (20) of at least one seat of the motor vehicle seat arrangement, which is fastened on a structural element (40) of the motor vehicle.

15. A motor vehicle, comprising:
-
a vehicle body including a structural element that is an integral element of a BIW (body in white) body of the motor vehicle; and a motor vehicle seat arrangement comprising at least one seat having a seat cushion with seating surface and a lower side facing away from the seating surface, the seat cushion having an unloaded state when not occupied and a loaded state when occupied by an occupant; and a measurement arrangement including a carrier fastened to the structural element, the carrier being formed by plastic; a support layer positioned on the carrier and being formed by an elastomer; at least one sensor formed as a foil-like measurement layer on the support layer and contacting the lower side of the seat cushion during the unloaded state and the loaded state, the at least one sensor configured to detect the loaded state of the seat cushion by detecting at least one of a deformation or a force loading of the lower side of the seat cushion. - View Dependent Claims (16)
