Abstract
A motor vehicle lock, in particular a motor vehicle door lock is provided with an actuation lever chain for a locking mechanism. The actuation lever chain has at least one actuation lever and a coupling element. A mass inertia element is also produced, which acts on the coupling element at least in the event of a crash. As well as a spring acting on the mass inertia element. According to the invention, the spring is designed to be double-acting, with a crash spring part and an engaging spring part.
Claims16
A motor vehicle lock comprising:
- a locking mechanism,
- an actuation lever chain for the locking mechanism, the actuation lever chain having at least one actuation lever and a coupling element,
- a mass inertia element which acts on the coupling element at least in the event of a crash, and
- a spring acting on the mass inertia element,
- wherein the spring is double-acting that comprises a crash spring part that holds the mass inertia element in a predetermined position relative to the actuation lever and an engaging spring part that preloads the mass inertia element toward a locking position, and
- wherein the coupling element comprises a locking region for a temporary coupling of the mass inertia element during a crash, and a pin receptacle for receiving a locking lever of the actuation lever chain.
A motor vehicle lock comprising:
- a locking mechanism,
- an actuation lever chain for the locking mechanism, the actuation lever chain having at least one actuation lever and a coupling element,
- a mass inertia element which acts on the coupling element at least in the event of a crash, and
- a spring acting on the mass inertia element,
- wherein the spring is double-acting that comprises a crash spring part that holds the mass inertia element in a predetermined position relative to the actuation lever and an engaging spring part that preloads the mass inertia element toward a locking position, and
- wherein the mass inertia element has a first mass inertia lever and a second mass inertia lever, wherein the second mass inertia lever is rotatably connected to the actuation lever, and wherein the first mass inertia lever is equipped with a winding portion as the engaging spring part.
A motor vehicle lock comprising:
- a locking mechanism,
- an actuation lever chain for the locking mechanism, the actuation lever chain having at least one actuation lever and a coupling element,
- a mass inertia element which acts on the coupling element at least in the event of a crash, and
- a spring acting on the mass inertia element,
- wherein the spring is double-acting that comprises a crash spring part that holds the mass inertia element in a predetermined position relative to the actuation lever and an engaging spring part that preloads the mass inertia element toward a locking position,
- wherein the mass inertia element is rotatably connected to the actuation lever with the interposition of the spring,
- further comprising a bearing pin passing through the actuation lever for the rotatable connection of the mass inertia element, and
- wherein the crash spring part of the spring engages around the bearing pin with a first winding portion.
