The invention relates to a device for distance measurement, comprising a transmission element ( ) for emitting pulsed acoustic or electromagnetic waves. Said transmission element is provided at a first end of a distance (L) or at a known distance from said first end. The device contains a receiving element ( ) for the emitted waves. Said receiving element ( ) receives said waves at a second end of the distance (L) or, after reflection at the second end, at the first end. An evaluation and control unit ( ) calculates the distance (L) from the running time and the signal speed. According to the invention, a telescope tube ( ) with two engaging tube elements ( ) is used between the first and second end. The transmission element ( ) and the receiving element ( ) are arranged on the tube elements ( ) respectively or are coupled thereto via waveguides. One of the tube elements can also be coupled to a displaceable element which can change location.

Device for measuring distance

The invention relates to a device for monitoring the locking position of a connecting device especially the locking position of a device for fixing a child seat in a motor vehicle, with a base body which can be connected with a support component capable of being locked with a locking component a slider arranged in the base body which when the base body is joined with the support component can be impinged at time of transfer of locking component to the locking position by the locking component and displaced from an initial position into an end position corresponding to the locking position, and with a detection device provided in or at the base body for detection of the correct locking position of the locking component and the support component by detection of the position of the slider whereby the detection device registers, in addition to the locking position, at least one additional position of the slider at a distance from the locking position.
