Abstract
A system for emergency opening of a door or window of a vehicle comprises an opening mechanism for forcing the door or window to open by means of pressure of hydraulic fluid, and an unlocking mechanism, which by means of hydraulic fluid is configured to unlock a lock of the door or window. The system may be connected to the brake system of a vehicle.
Claims13
A system for emergency opening of a vehicle access point of a vehicle, comprising:
- an unlocking mechanism configured to open a lock provided on the vehicle access point, the lock comprising a piston locking the lock, wherein the unlocking mechanism comprises a hydraulic unit configured, when activated, to exert a mechanical force onto the piston by introducing a pressure of hydraulic fluid into the hydraulic unit, thereby unlocking the lock;
- an opening mechanism with a hydraulic cylinder coupled to a cover positioned over the vehicle access point and the vehicle, the hydraulic cylinder having a first end coupled to the vehicle and a second end coupled to the cover such that upon expansion of the hydraulic cylinder the cover is urged outwardly from the vehicle access point;
- a first hydraulic opening valve provided on the inside of the vehicle, wherein the unlocking mechanism is configured to be activated by the first opening valve;
- a second hydraulic opening valve provided on the outside of the vehicle, wherein the unlocking mechanism is configured to be activated by the second opening valve;
- and
- a hydraulic blocking valve provided on the inside of the vehicle and configured to block the hydraulic fluid flow to the second opening valve, when activated.

A system for emergency opening of a vehicle access point of a vehicle, comprising:
- an unlocking mechanism operably coupled to a lock provided on the vehicle access point, the lock comprising a piston having a locked state and an unlocked state, wherein the unlocking mechanism comprises a hydraulic unit engaging the lock and positioned such that hydraulic pressure in the hydraulic unit urges the lock from the locked state to the unlocked state;
- an opening mechanism with a hydraulic cylinder and piston assembly coupled to a cover positioned over the vehicle access point and the vehicle, the hydraulic cylinder and piston assembly having a first end coupled to the vehicle and a second end coupled to the cover such that upon expansion of the hydraulic cylinder and piston assembly the cover is urged outwardly from the vehicle access point;
- a first hydraulic opening valve provided on the inside of the vehicle and coupled to the unlocking mechanism, wherein the first hydraulic opening valve has a first open state in which the first hydraulic opening valve couples a hydraulic pressure source to the hydraulic unit of the unlocking mechanism and a first closed state in which the first hydraulic opening valve does not couple the hydraulic pressure source to the hydraulic unit of the unlocking mechanism;
- a second hydraulic opening valve mounted to the outside of the vehicle and coupled to the unlocking mechanism, wherein the second hydraulic opening valve second a first open state in which the second hydraulic opening valve couples a hydraulic pressure source to the hydraulic unit of the unlocking mechanism and a second closed state in which the second hydraulic opening valve does not couple the hydraulic pressure source to the hydraulic unit of the unlocking mechanism;
- and
- a hydraulic blocking valve provided on the inside of the vehicle and positioned within a hydraulic flow path between the hydraulic pressure source and the second hydraulic opening and not positioned within a hydraulic flow path between the hydraulic pressure source and the first hydraulic opening valve, the hydraulic blocking valve having an open state in which the hydraulic blocking valve couples the hydraulic pressure source to the second hydraulic opening valve and a closed state in which the hydraulic blocking valve couples the hydraulic pressure source to the second hydraulic valve.
