As a preference of the present invention, the wind umbrella cover that integrates is rigid plastics, and bevel angle is 120 ° ~ 150 °.
As a preference of the present invention, the portion that struts is covered in group on the reinforcing rib of circumference array distribution by flexible film
Into the portion of strutting struts rear outer surface and offsets with the collection wind umbrella cover inner surface, maximum distraction angle and the collection wind
Umbrella cover angle is identical.
The portion of strutting struts rear middle part and is played a supporting role by the collection wind umbrella cover as a result, is strutted described in reinforcement
The stability in portion will not turn over because wind-force is excessive.
As a preference of the present invention, covered with protective pad, the protective pad on the safety air cushion of the cage bottom
For soft material.
It will not directly be trampled on the safety air cushion when people walks in the car as a result, the safety will not be made
Air cushion friction and it is damaged.
As a preference of the present invention, fitting is installed on the car bottom surface, two sides during the safety air cushion unaerated
And medial surface, and side setting height(from bottom) is more than 1m.
In conclusion the invention has the advantages that：
The wind-force pressure generated when the elevator with safety air cushion is quickly dropped elevator using wind-drive device in the car of the present invention
Into the safety air cushion in car, the personnel in car are protected from shocking damage.
