Abstract

The invention concerns an impact sensor consisting of at least two deformable hollow bodies (2.a, 2.b) and at least one pressure sensor (1.2.a, 1.2.b) in each case for detecting the pressure change in the respective hollow body, wherein the pressure sensors (1.2.a, 1.2.b) are arranged on a common circuit carrier in a common housing (1), and a pressure supply region (1.3.a, 1.3b) which is sealed with respect to the other pressure supply region is provided for each pressure sensor (1.2.a, 1.2.b) in the housing (1).
