AI Technical Summary

Technical Problem

Existing door handle arrangements in vehicles can unintentionally open during critical situations like accidents, compromising occupant safety due to high transverse acceleration actuating the handle body.

Method used

A door handle arrangement with dual sensors and a control device that checks the operating speed of the handle body, preventing release of movable components if the speed exceeds a permissible limit, ensuring safety by locking the components during critical situations.

Benefits of technology

Enhances safety by preventing unintended movement of vehicle doors or flaps during accidents, maintaining occupant protection by locking components if the handle body's speed is impermissible.

Abstract

Door handle arrangement (1) for a movable component (2) of a vehicle (3), - with a handle body (4) which is movable between a rest position (5) and an actuating position (6) along a stroke path (7), - with a control device (13), - with a first sensor device (8) which can be triggered at a first trigger position (10) with respect to the stroke (7) when the handle body (4) moves from the rest position (5) into the actuating position (6), - with a locking device (14) for releasing or locking the movable component (2) of a vehicle (3), - wherein the locking device (14) is communicatively connected to the control device (13), characterized in that - that the door handle arrangement (1) has a second sensor device (9) which can be triggered at a second triggering position (11) with respect to the stroke (7) when the handle body (4) moves from the rest position (5) into the actuating position (6), - that the first trigger position (10) and the second trigger position (11) are offset by a predefined stroke distance (12) with respect to the stroke (7) of the handle body (4), - that the first sensor device (8) and the second sensor device (9) are communicatively connected to the control device (13) in order to transmit measurement signals to the control device (13), - that the control device (13) is designed and / or programmed to carry out an admissibility test of the operating speed of the handle body (4).
