AI Technical Summary

Technical Problem

Existing anti-opening devices in land vehicle side doors fail to reliably prevent door opening during side impacts due to vibration-induced unlocking of locking blades, risking passenger ejection.

Method used

A non-reversible anti-opening device with a locking piece mounted for rotation and translation, utilizing a protrusion and spring mechanism to maintain the locking piece in a position preventing the control lever's rotation, eliminating the need for locking blades and their fastening means.

Benefits of technology

Ensures the locking piece remains in a position preventing the control lever's rotation, effectively preventing door opening post-impact, thus enhancing safety by eliminating vibration-induced unlocking.

Abstract

An opening handle (PO) is fitted to a side door of a land vehicle and includes a control lever rotatably mounted on a bracket (EP) and a locking piece (PB) rotatably mounted on the bracket (EP) around a predetermined direction and under the restoring force of a spring to move from a first position to a second position preventing rotation of the control lever when the vehicle sustains a side impact. The locking piece (PB) is mounted in translation along the predetermined direction so that it is translated by the spring from the second position to a third position preventing rotation of the control lever, and after the impact to move into a fourth position in which a protrusion (PP) of the bracket (EP) constrains it to continue preventing rotation of the control lever.
