Motor vehicle occupant e.g. child, retaining device, has transponder generating respective electromagnetic signals, when antenna parts are in contact and spaced apart from each other and when locking unit is in inactive and active state

摘要

The device has a transponder generating one electromagnetic signal, when antenna parts (44, 46) of the transponder contact each other and a locking unit is in inactive state. The transponder generates another electromagnetic signal, when the antenna parts are spaced from each other and the locking unit is in active state. A base receiver identifies the electromagnetic signals generated by the transponder. An independent claim is also included for a motor vehicle seat assembly comprising a vehicle occupant retaining device.
