Seat impact absorbing structure

Abstract

The utility model relates to a seat anti -impact energy -absorbing structure, including first protective pad, second protective pad, base and fixed plate, first protective pad fixed mounting is at the surface of base, the fixed plate is embedded in the surface of second protective pad. The utility model protects the neck of driver and passenger through first protective pad and second protective pad under normal circumstances, when the emergency brake, acceleration sensor senses the vehicle anomaly to drive the electric push rod action through the controller, makes the locking structure unlock, spring and torsional spring can drive second protective pad to move towards the direction close to the neck of driver and passenger through fixed plate at this moment, make the neck of driver and passenger be able to contact with second protective pad first when moving back, to play the role of buffering energy -absorbing, then can drive spring and torsional spring deformation through second protective pad and fixed plate, further play the role of buffering energy -absorbing, to protect the neck.
