System of devices for emergency opening of vehicle doors
First Claim
1. A system of devices for emergency opening of vehicle doors, especially to open from inside the door(s) blocked or jammed following a traffic accident, including means for vehicle door displacement to opened position, with simultaneous unlocking of vehicle-door locking unit, wherein a door opening executing element of said system is a pneumatic servomotor (1) supplied with pressure from at least two pyrotechnical charges or cartridges (2) and (3), whereas an electrical signal for blowing up the first pyrotechnical cartridge (2), is given by an electric circuit of sensors (4), consisting of consecutively activated:
- crush sensor (5), shock or acceleration sensor (6), and tilt sensor (7), sending a signal to electronic cartridge-blowing unit (8) controlling the process of blowing up a pyrotechnical charge or cartridge (2), whereas the necessity to blow up a subsequent pyrotechnical cartridge (3) and any further cartridges is controlled by a sensor (9) of pressure inside the pneumatic servomotor (1), whereas a blowup time interval is govemed by an electronic cartridge-blowing unit (8), whereas the retraction of the rod of the pneumatic-servomotor (1) to its original position is executed by an electrovalve (10), which receives the electric signal from either a pressure sensor (9) or a displacement sensor, temperature sensor or time relay, depending on the sequence of events causing the respective signalization by these control sensors additionally mounted in the vehicle.
