Yet further, the length of the connecting rod of described pan frontward end is longer than the length of rear end link.
After taking above technical scheme, the invention have the benefit that
After colliding, due to inertia, the personnel on safety seat forwards fly out, owing to seat belt is by personnel and emergency seat
The base of chair is linked to be an entirety, and personnel travel forward together with the seat board of seat, and the spring in buffering slide bar passes through seat board
Slide-bar, to the personnel's buffering energy-absorbing on seat board and seat board, produces protection for the first time；During buffering, owing to personnel make at inertia
Dishing out forward under with, therefore base creates component forwardly and upwardly, component upwards is by the seat board slide-bar band on seat board
Dynamic buffering slide bar is relative to square tube generation relative movement, and swings forward under the effect of two end links, in swing process, slow
Rush the extension spring between slide bar and square tube to wobbling action buffering energy-absorbing, formation second time protection；After swinging to certain position, the end
Seat back segment limits, with ratchet Suo Neng mechanism, the amplitude swung and prevents resilience, and the lock-stopping hinge mechanism of pan frontward end ejects front
Connecting rod spacing, it is to avoid reach the limit of the recoil strength behind position and human body damaged, formed third time protection.
After this technical scheme, by the way of coiling machine active roll ejects, the momentum produced during to collision divides fully
Section ground buffering and absorption, it is ensured that the peak value of impact, in the scope less to human injury, more efficiently decreases injury.
