ACTIVE BOLSTER FOR PEDESTRIAN PROTECTION Russian patent published in 2018 - IPC B60R21/205 B60R21/2165 B60R21/36 

FIELD: motor industry.

SUBSTANCE: group of inventions relates to embodiments of a device for protecting a pedestrian during a collision with a vehicle. Vehicle instrument panel has a pedestrian protection zone along a forward side. Instrument panel generally has a low stiffness that avoids impact forces in the pedestrian protection zone greater than a predetermined force. Accessory component mounted on the instrument panel within the protection zone has a stiffness that could generate an impact force above the predetermined force. Cover providing a trim surface of the instrument panel has an annular wall region between inner and outer tear seams which encompass the accessory component. Annular bladder wall joined to the annular wall region forms a substantially toroidal expandable chamber. Inflator is arranged to supply an inflation gas into the expandable chamber during an impact of a pedestrian to tear the tear seams and expand the expandable chamber above the instrument panel body to intercept the pedestrian prior to impacting the accessory component.

EFFECT: higher safety.
