Abstract

A double-armed hinge for use in a motor vehicle, includes a first bar for fastening to a front bonnet of said motor vehicle, a second bar for fastening to a body of said motor vehicle, a first arm, a second arm, and a thrust piece. At least one of said first arm and said second arm is constructed in two parts and includes a first strut and a second strut. The thrust piece thrust piece is applied to one of said first strut and said second strut. The thrust piece includes a head configured to grip behind the first or second strut. The first and second struts are pivotably connected to each other by a connecting joint and rigidly braced to each other by a connection device. The connecting device yields under a given load so that, under a sudden load that exceeds the given load, the connection device breaks and the first and second bars come closer to each other substantially without resistance.
