METHOD FOR ACTIVATION OF A SAFETY ARRANGEMENT IN A VEHICLE

摘要

The invention relates to an arrangement for activation of a safety arrangement in a pedal arrangement for vehicles, comprising a pedal arm (2) and a push rod (8) which connects the pedal arm (2) with means (9) arranged to act upon the pedal arm (2), actuation means (6, 7, 10; 21; 31) for releasing the push rod (8) from the pedal arm (2) and a sensor device (14, 15; 25; 37) for activation of said actuation means (6, 7, 10; 21; 31) in the case of detection of a condition generally corresponding to a collision. The invention is characterized in that said sensor device (14, 15; 25; 37) and said actuation means (6, 7, 10; 21; 31) are arranged to release the push rod (8) from the pedal arm (2) before any part of the engine of said vehicle or any other component in the engine compartment acts upon the push rod (8). The invention also relates to a method in connection with such a release of the push rod (8). By means of the invention, an improved pedal arrangement is obtained which is mainly intended for vehicles and which comprises a pedal arm, which for example forms part of a brake pedal and which can be released from a push rod in a quick and effective manner in the event of a collision.
