Energy absorbing device with torso displacement limiter
First Claim
1. An energy absorbing device with torso displacement limiter to be applied to any seatbelt (C) model characterized bya laminated plate (2) fastened to a retractor body (R) of a seatbelt, presenting predetermined resistance and malleability characteristics and provided with a plurality of folds (3) arranged parallelly among themselves and transversally in relation to a longitudinal axle of said laminated plate;
- said plurality of folds, when submitted to a certain traction strength resulting from strong collision or sudden deceleration of a vehicle, are gradually unfoldable, causing a gradual increase in the length of said laminated plate (2);
further characterized by an additional element (4), wired type and with restraint effect, conveniently installed in the retractor body (R), having predetermined resistance and malleability characteristics and provided with a plurality of turns (5) that, when submitted to a certain traction strength resulting from strong collision or sudden deceleration of said vehicle, are gradually unfolded, causing a gradual increase in length of said additional element (4).

Abstract
An energy absorbing device with torso displacement limiter to be applied to any seatbelt model is characterized by a laminated plate conveniently fastened to a retractor body of a seatbelt. The device presents predetermined resistance and malleability characteristics and is provided with a convenient number of folds arranged in parallel with respect to each other and transversally with respect to the longitudinal axis of the plate. The folds, when submitted to a certain traction strength resulting from a strong collision or sudden deceleration of a vehicle in which they are being used, are gradually unfolded, causing a gradual increase in the length of plate.
