Abstract
The invention relates to a motor vehicle lock, in particular a motor vehicle door lock, which is equipped with a locking mechanism (1, 2) composed, essentially, of a rotary latch (1) and a pawl (2). Furthermore, a securing device (5, 6, 7, 8) and and an emergency actuation element (9, 10, 11) for the securing device are realized. The securing device (5, 6, 7, 8) has at least one securing lever (5), which can be acted upon both by a first motor drive (7) and by an emergency actuation lever (10) as part of the emergency actuation element (9, 10, 11). According to the invention, the first securing lever (5) has a spring (5a) for positioning the first securing lever.
Claims16
A motor vehicle latch comprising:
- a locking mechanism having a catch and a pawl,
- a securing device, and
- an emergency actuation element for the securing device, the securing device having a first securing lever acted upon both by a motor drive and by an emergency actuation lever component of the emergency actuation element,
- wherein the first securing lever has a guide groove formed in the first securing lever shaped for receiving a housing pin formed on a lock housing of the motor vehicle latch and a spring, wherein the quide groove moves with respect to the housing pin such that the first securing lever is positioned in any one of functional positions including “anti-theft device ON” and “anti-theft device OFF,” and
- the securing device further having a second securing lever, the first securing lever being designed as an anti-theft securing lever and the second securing lever being a central locking lever, the two securing levers being mounted on a same axis of rotation.
A motor vehicle latch comprising:
- a locking mechanism having a catch and a pawl,
- a securing device, and
- an emergency actuation element for the securing device, the securing device having a first securing lever acted upon both by a motor drive and by an emergency actuation lever component of the emergency actuation element,
- wherein the first securing lever has a spring for being positioned in any one of functional positions including “anti-theft device ON” and “anti-theft device OFF,” and
- the securing device further having a second securing lever, the first securing lever being designed as an anti-theft securing lever and the second securing lever being a central locking lever, the two securing levers being mounted on a same axis of rotation,
- wherein the first securing lever has a guide groove for a housing pin,
- wherein the guide groove has an enlarged cross section in a region of each of two end positions of the first securing lever,
- wherein the guide groove is delimited in its longitudinal extension on one side by a radially inner stop wall with respect to an axis of rotation of the securing lever and, on an opposing side, by a radially outer spring wall, and
- wherein the spring wall, in a region of the two end positions of the securing lever, is reinforced with material thickening in comparison with a connection region between the two end positions.
A motor vehicle latch comprising:
- a locking mechanism having a catch and a pawl,
- a securing device, and
