Motor vehicle seat with integrated occupation detector
First Claim
1. Motor vehicle seat with integrated occupation detector, comprisingan upper frame, said upper frame supporting a seat upholstery or a seat shell, and a lower frame, said lower frame being secured in the motor vehicle, at least one mechanical mounting element to support the upper frame in the lower frame and to introduce a weight force from the upper frame into the lower frame, said mounting element being designed so as to deform elastically under the weight of a seat user, said elastic deformation causing a vertical displacement between the upper frame and the lower frame, and at least one measuring sensor for measuring an elastic deformation of said mounting element, said measuring sensor comprising a switching element, said switching element measuring the vertical displacement between the upper frame and the lower frame as the exceeding of a predetermined threshold value.

Abstract
A motor vehicle seat with integrated occupation detector is featured having an upper frame, which supports seat upholstery or a seat shell, and a lower frame, which is secured in the vehicle, and mechanical mounting elements to support the upper frame in the lower frame. The mounting elements are designed in such a way that they are deformed elastically under the weight of a seat user, the occupation detector comprising at least one measuring pick-up, which measures the elastic deformation of the mounting elements.
