1. A door handle module for a vehicle, comprising:
- a door handle, movably mounted in a support frame for the opening of a door or hatch by a user, the door handle having at least one rest position and one working position,a mechanical coupling unit, through which a movement of the door handle from the rest position to the working position can be transferred to a lock,a crash lock, which prevents movement of the door handle and/or coupling unit during action of an acceleration force, so that activation of the lock is avoided,a securing element, andan additional spring;
wherein the crash lock activates the additional spring by cooperating with the securing element during the action of the acceleration force, in which case the additional spring exerts a spring force in the form of an additional force on moving door handle, in order to force the door handle into the at least one rest position, wherein the crash lock remains activated after a first activation, and the door handle can be fully activated,wherein (a) the securing element comprises a snap-in device and the crash lock comprises a mating snap-in device, and during the action of the acceleration force the snap-in device is structured to cooperate with the mating snap-in device for activation of the additional spring, or(b) the securing element is a switch spring, wherein one end of the switch spring cooperates in shape-mated fashion with the crash lock and the other end of the switch spring cooperates in shape-mated fashion with the support frame, in order to provide a first and a second stable position to the securing element.

Abstract
The invention concerns a door handle module for a vehicle with a door handle, which is mounted to move in a support frame for the opening of a door or hatch by a user, the door handle having at least one rest position and one working position, a mechanical coupling unit, through which movement of the door handle from the rest position to the working position can be transferred to a lock, a crash lock, which prevents movement of the door handle and/or coupling unit during the action of an acceleration force, especially during an accident, so that activation of the lock is avoided.

13. A method for securing a door handle module, comprising:
-
mounting a door handle to move in a support frame for an opening of a door or hatch by a user, the door handle having at least one rest position and one working position, transferring a movement of the door handle to a lock from the rest position to the working position, through a mechanical coupling unit, preventing movement of the door handle and/or coupling unit with a crash lock during action of an acceleration force so that activation of the lock is avoided, activating an additional spring by the crash lock, during the action of the acceleration force, the additional spring exerting a spring force in the form of an additional force on the moving door handle, in order to force the door handle into the at least one rest position, wherein the crash lock remains activated after a first activation, and the door handle can be fully activated, wherein the door handle module comprises; a securing element, and the additional spring, wherein the crash lock engages during the action of an acceleration force so that activation of the lock is avoided, wherein (a) the securing element comprises a snap-in device and the crash lock comprises a mating snap-in device, and during the action of the acceleration force the snap-in device is structured to cooperate with the mating snap-in device for activation of the additional spring, or (b) the securing element is a switch spring, wherein one end of the switch spring cooperates in shape-mated fashion with the crash lock and the other end of the switch spring cooperates in shape-mated fashion with the support frame, in order to provide a first and a second stable position to the securing element.

14. A door handle module for a vehicle, comprising:
-
a door handle, movably mounted in a support frame for the opening of a door or hatch by a user, the door handle having at least one rest position and one working position, a mechanical coupling unit, through which a movement of the door handle from the rest position to the working position can be transferred to a lock, a crash lock, which prevents movement of the door handle and/or coupling unit during action of an acceleration force, so that activation of the lock is avoided, the crash lock further comprising; a beveled pin, a cam with a cutout arranged to receive the beveled pin, a first spring, and an additional spring; wherein the crash lock activates the additional spring by slidably engaging the beveled pin with the cam during the action of the acceleration force, in which case the additional spring exerts a spring force in the form of an additional force on moving door handle, in order to force the door handle into the at least one rest position, wherein the crash lock remains activated after a first activation, and the door handle can be fully activated.

15. A method for securing a door handle module, comprising:
-
mounting a door handle to move in a support frame for an opening of a door or hatch by a user, the door handle having at least one rest position and one working position, transferring a movement of the door handle to a lock from the rest position to the working position, through a mechanical coupling unit, preventing movement of the door handle and/or coupling unit with a crash lock, comprising; a beveled tipped securing pin, a cam with a cutout arranged to receive the said beveled pin, a first spring, and an additional spring; the crash lock slidably engages during action of an acceleration force so that activation of the lock is avoided, activating the additional spring by the crash lock, during the action of the acceleration force, the additional spring exerting a spring force in the form of an additional force on the moving door handle, in order to force the door handle into the at least one rest position wherein the crash lock remains activated after a first activation, and the door handle can be fully activated.
