Definitions

• the invention relates to an adjusting mechanism for a motor vehicle lock arrangement according to the preamble of claim 1 and a motor vehicle lock arrangement according to claim 16.
• the adjustment mechanism in question is assigned to a motor vehicle lock system that has a motor vehicle lock.
• a motor vehicle lock is used in all types of locking elements of a motor vehicle. These include, in particular, side doors, rear doors, tailgates, trunk lids, front hoods, in particular engine hoods. These closure elements can be designed in the manner of pivoting doors or in the manner of sliding doors.
• the known adjusting mechanism (DE 202015 106321 U1), from which the invention is based, is assigned to a motor vehicle lock arrangement with a motor vehicle lock.
• the adjustment mechanism is used here to implement a motorized opening process and has an electric drive motor, an adjustment element in the form of a pulley and a drive cable between the drive motor and the adjustment element, which forms a drive train.
• a motorized forward movement and an opposing, spring-geared return movement of the adjusting element is provided in a movement cycle.
• the drive cable unwinds from a drive shaft of the drive motor.
• the adjusting element hits the return end stop in a spring-driven manner.
• the adjusting element can rebound here. It cannot be ruled out that this is associated with noise development that is perceived as a loss of comfort.
• the invention is based on the problem of designing and developing the known adjusting mechanism in such a way that the operating behavior with regard to the impact on an end stop is improved.
• the above problem is solved in an adjusting mechanism according to the Oberbe of claim 1 by the features of the characterizing part of claim 1.
• the proposed solution is based on the fundamental consideration that a bellows-like buffer element can optimally absorb the kinetic energy of the adjustment element during the spring-driven return movement and / or during the, in particular motor-driven, forward movement due to its elastic deformability.
• a bellows-like buffer element when it comes into contact with a contact surface of another component of the adjusting mechanism, is able to deflect in a defined manner and to brake the movement of the adjusting element in a targeted manner. This is preferably done in such a way that a rebound of the adjusting element in the course of its forward or backward movement is completely avoided or at least significantly reduced.
• a component with mutually foldable axial sections in particular wall sections, is meant, the material of which is only subjected to bending stress when axially compressed and is not, or at least not significantly, compressed or compressed in the axial direction. Due to the axial compression, the spatial position of some of the axial sections of the construction changes in part by folding them together. Each of the mutually adjacent portions of the mutually changing position are richly connected to one another in a connection area, the bending stress occurring in this connection area due to the folding. In order to cause such a folding when axially compressed, the outer contour has a meandering course in the axial cross section, that is, a course in which radially vorste existing sections and radially recessed sections alternate.
• the component can be configured as a hose in the axial area of the meandering outer contour, that is to say form the cavity extending axially along a plurality of the radially protruding sections and radially recessed sections.
• several hollow sections are axially aligned, these sections being axially separated from one another by the material of the component. In the area of two radially opposite, radially recessed sections, there is therefore a material bond between these sections in the radial direction and thus not axially continuous cavity.
• the term "bellows-like" is to be understood broadly in this respect.
• the respective end stop and / or the engagement element have a bellows-like buffer element which is axially deflected when the engagement element strikes this end stop.
• the Verstellme mechanism has a housing which is used to mount the adjusting element and to which the respective end stop, ie the back end stop and / or back end stop, is assigned.
• “Assigned” in this context means that the respective end stop is either formed directly by a housing section of the housing or by the buffer element, which in this case is fixed to the housing, ie is fixed to the housing (claim 3).
• Such a buffer element can additionally or alternatively also be part of the adjustment element, so it can be moved as a whole relative to the housing (claim 4), in which case the respective end stop is then formed directly by a housing section.
• Claim 5 defines a return spring, for example a leg spring, via which the adjusting element is pretensioned in the direction of the rear end stop and thereby causes the return movement.
• the buffer element initially springs in and then rebounds during the respective movement, that is to say the return movement and / or forward movement, of the adjusting element.
• the buffer element is constantly in contact with the respective contact surface with which the buffer element meets during the respective movement, both during compression and during rebound. The adjusting element then does not bounce back. After the rebound, further compression and rebound movements can follow until the kinetic energy of the adjusting element is completely absorbed, the contact between the buffer element and the respective contact surface preferably remaining throughout this period.
• Claim 7 defines particularly preferred length ratios between the maximally compressed state and the unloaded state.
• the unloaded state is the state of the buffer element in which it is not in contact with the respective contact surface.
• Preferred options for otherwise fixing the buffer element on the housing or on the adjusting element are defined in claim 13. This is particularly preferably done by means of a plug connection, in particular a plug connection between the buffer element and the housing.
• Claim 14 defines preferred configurations of the adjusting element.
