Measuring device and method for measuring a seat mat for a vehicle seat
First Claim
1. A measurement apparatus for measuring a seat mat of a vehicle seat, the seat mat including two films provided with pressure sensors between which at least one cavity is present, a plastic layer arranged between the two films, and a venting conduit, the measurement apparatus comprising:
- a suction connector for connection to the venting conduit;
a pump for generating a negative pressure in the seat mat;
a controller for establishing a pressure difference between the negative pressure in the seat mat and an external air pressure;
a recording apparatus for reading the pressure sensors; and
an arrangement for at least one of optically outputting a reading of the pressure sensors and storing the reading.

Abstract
A measurement apparatus and a method for measuring a seat mat for a vehicle seat which serve to perform a function test or a recording of readings by way of a negative pressure that is generated in the seat mat. The negative pressure is established by way of a pressure difference between the negative pressure and the external atmospheric pressure. The method is thus independent of the external atmospheric pressure. The controller that establishes the pressure difference is embodied either electronically or mechanically.

4. A method for measuring a seat mat for a vehicle seat, comprising:
-
exposing the seat mat to a pressure load for at least one of;
i) performing a recording of a reading, and ii) performing a function test;
establishing a negative pressure in the seat mat in order to generate a pressure load; and
controlling a pressure difference in the seat mat between the negative pressure in the seat mat and an air pressure in an environment. - View Dependent Claims (5, 6, 7)
