A SAFETY DEVICE FOR A VEHICLE SEAT. A FRAME FOR SAID SEAT AND A VEHICLE COMPRISING SAID DEVICE.

摘要

A safety device for a seat (100) of a vehicle (200), comprises a guide element (2) developing along a main axis thereof such as to define an operative direction (A) of the device and provided with rigid connecting means (5) with a platform (202) of the vehicle (200), an end stop (6) rigidly connected to an end portion (2a) of the guide element (2) and a slider (3) provided with rigid connecting means (7) to the seat (100), and slidably associated to the guide element (2) such as to slide with respect thereto along the operative direction (A), in a nearing to or distancing direction from the end stop (6). The device further comprises a damping body (4) operatively interposed between the slider (3) and the end stop (6) along the operative direction (A) and exhibiting a ductile structure configured such as to plastically deform following a displacement of the slider (3) along the guide element (2), in a direction nearing to or a distancing from the end stop (6), opposing said displacement in order to reduce a velocity thereof.
