HIGHER VEHICLE SEAT SAFETY SYSTEM FOR SEAT USER Russian patent published in 2015 - IPC B60N2/42 B60R19/02 B60R21/08 

FIELD: transport.

SUBSTANCE: claimed system comprises the mechanism for control over limited displacement in direction of inertia forces and for locking at the seat initial and final positions. The seat is fitted by its bores at its lower props on two slide guides rigidly coupled with the body at the ends and provided with retainers of the seat initial and final positions with elastoplastic damping elements. Control mechanism is composed of two sleeves fitted on every guide in the thrust between the seat rear surface and attachment of the guide to the body. Said sleeves are made of the material destructing at stretching load magnitude corresponding to preset minimum magnitude of inertial overloads dangerous for seat user at emergent braking. Steel coiled helical spring is concentrically fitted in the body of every sleeve and rigidly connected by its ends with the seat rear surface and the body.

EFFECT: simplified design, higher safety at accident.
