VEHICLE PROTECTIVE DEVICE Russian patent published in 2006 - IPC B60R21/16 

FIELD: transport engineering; passive safety devices.

SUBSTANCE: invention relates to vehicle passive safety devices designed for protection of passengers at collusion causing sharp reduction of speed. Proposed device has collision detector 1, compressed air source 2, mode selector unit 3, controlled reducer 4, pneumatic collectors 5 and 19, electromagnetic valves 6-9, 20, air bags 10-13 of front left-hand, front right-hand, rear left-hand and rear right-hand seats, respectively, diffusers 14-17, vehicle cab 18, pneumatic system forced pressure bleeding switch 21, foot switch 22, switches 23-26 connected with doors, push-button switch 27-30 connected with seats, OR gate 31, sound alarm 32, pilot lamp 33, coding unit 34, high-frequency generator 35, phase keyer 26, power amplifier 37 and transmitting antenna 38. Check point contains receiving antenna, high-frequency amplifier, mixer, search unit, heterodyne, intermediate frequency amplifier, phase-shift keyed signal detector, spectrum width meters, frequency doubler, comparator unit, threshold unit, delay line, switch, phase-shift keyed signal demodulator, multipliers, narrow-band filter, low frequency filter and recording unit.

EFFECT: enlarged functional capabilities of device owing to remote transmission of distress signal to check point in case of collision of road or attack of deliberate criminals-passengers of drive.
