Abstract
A door handle for vehicles includes a connecting member adapted to act on a lock when the handle is actuated, and a normally inactive crash locking unit for the connecting member. A crash sensor is connected to the crash locking unit so as to activate the crash locking unit in the event of a crash, so that the crash locking unit blocks the connecting member and the inertia forces which act to actuate the handle are not transmitted to the lock. The connecting member includes a drive member movable together with the connecting member, and the drive member is mounted in a liquid medium so as to be moved in this medium when the connecting member is moved. The viscosity of the medium changes in dependence on an electrical field acting in the medium. The crash sensor controls the electrical field prevailing in the medium.
