Multiple engagement locking device
First Claim
1. A locking device for a motor vehicle, the locking device comprising:
- a locking mechanism,a motor drive,an actuating lever comprising a pair of engagement lugs arranged in succession, wherein the actuating lever is operatively coupled to a handle,an unlocking lever operatively connected to the locking mechanism, wherein the unlocking lever defines a slotted hole,a coupling lever which includes a pin positioned in the slotted hole of the unlocking lever such that movement of the coupling lever moves the unlocking lever, wherein the coupling lever is, in an “
unlocked state”
, operatively coupled to the actuating lever by the pair of engagement lugs such that movement of the actuating lever moves the coupling lever and is, in an “
locked state”
, operatively decoupled from the actuating lever and wherein the coupling lever is operatively coupled to the motor drive such that actuation of the motor drive moves the coupling lever, for shifting between the “
unlocked state” and
the “
locked state”
,wherein each of such engagement lugs are formed by an element projecting from the base area of the actuating lever.

Abstract
The invention relates to a locking device, in particular for a motor vehicle, having a catch mechanism and a coupling device for connecting to a motor drive. The coupling device comprises a coupling lever, which by virtue of a plurality of engagement lugs is able to pivot a coupling lever. The engagement lugs can be detected in succession by the coupling lever and are arranged in this respect one behind the other. The invention further relates to a plastics component for the locking device. An engagement lug is formed by an element protruding from a main face of the coupling lever in order to simplify production and to keep material costs and installation space to a minimum.
