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.

A vehicle door handle for use on a motor vehicle includes a handle and a handle support, the handle being mounted in the handle support, the handle is configured in the form of an elongated body, with a first end section, a second end section and a gripping section. Bearing sections project into the handle support and are supported there. In a cavity of the handle, an antenna for UWB signal transmission is arranged and coupled with a control circuit. In a further development of the invention, it is coupled with a proximity sensor. An authentication system and the use of an inventive vehicle door handle in an authentication system is also disclosed.
