Abstract
An impact detection arrangement for a motor vehicle has at least one pressure body in a side door region of the motor vehicle. The at least one pressure body is connected to a pressure sensor via a connecting line. Additionally, the at least one pressure body is provided in an impact region that is relevant to a fixed pole side crash test, and is adapted to this region.
Claims15
An impact detection arrangement for a motor vehicle, comprising:
- a pressure sensor and at least one elongate pressure body connected to the pressure sensor via a connecting line, the at least one elongate pressure body being disposed in an impact region of a side door of the motor vehicle and extending diagonally across said region, the pressure sensor being operative to generate a signal to trigger a vehicle occupant protection device, a Y branching element in the connecting line between the at least one pressure body and the pressure sensor, the Y branching element having an output connected to the pressure sensor, a first input connected to the pressure body and a second input configured to communicate with a pressure volume between an inside door panel and an outside door panel of the side door, a valve configured to communicate with the at least one pressure body or the connecting line, the valve being operative to open at and above a predefined pressure to prevent an inward deformation of the inside door panel in a way that could prevent deployment of the vehicle occupant protection device.
An impact detection arrangement configured to detect an impact at a side door of a motor vehicle, the side door having inner and outer panels defining a pressure volume therebetween, the arrangement comprising:
- an elongate deformable pressure body extending diagonally across the pressure volume of the side door from an upper position to a lower position and abutting at least one of the inner and outer panels;
- a pressure sensor in the pressure volume of the side door;
- a connecting line having an output connected to the pressure sensor, a first input connected to the pressure body and a second input connected to parts of the pressure volume external of the pressure body, a non-return valve in communication with the output so that a change in volume of the pressure body or in the pressure volume generates a pressure change that is detectable by the pressure sensor;
- and
- a valve configured to communicate with the pressure body or the connecting line, the valve being operative to open at and above a predefined pressure, to prevent an inward deformation of an inner panel of the side door in a way that could prevent deployment of the vehicle occupant protection device.
